Ravens Win the Super Bowl: Win Today and We Will Walk Together Forever

Ravens Win the Super Bowl:  Win Today and We Will Walk Together Forever

Normally, this is where you would "crow" about predicting that the Ravens would win the Super Bowl--something we did the day after the AFC and NFC championship games.  Two weeks ago.  On this blog.  We predicted, prognosticated and told you they would win.  

Except maybe "rave" or "raven" about it would be a better word.  

CROW v RAVEN.  We can "Crow" about our "Ravens" pick now.


Giving us a 9-2 record overall, and a weighted record that was unbelievable throughout the playoffs, as we predicted both the NFC and AFC championship games as well as the the Super Bowl, correctly.  We only made two mistakes along the way.  

The Ravens were huge underdogs and no one would pick them.  Nearly everyone picked the Niners, and the line in Vegas was hugely to the Niners' favor.  

The actual game was pretty interesting.  Baltimore got off to a big lead.  Then for some reason the power went out in the SuperDome.  

This reminded us of the time the power went out on the Ford-Carter Presidential Debate in 1976 in Philadelphia, although to be honest, that debate was so boring, many people were relieved the power had gone out.

Engineer JACK LEMMON warned them this could happen--the CHINA SYNDROME could result in a  COMPLETE LOSS OF POWER DURING THE SUPER BOWL not to mention a nuclear catastrophe.  


The power outage was definitely a help to the 49ers, who up until that point had been exhausted by the physicality, intimidation and brutality of the Ravens' defense.  Colin Kaepernick, who appears to be a lineal descendant of Copernicus (their names seem to be the same) (ok, he's adopted, but it's working for us) had, up until the break, performed exactly as we predicted a neophyte QB might perform in a Super Bowl--wretchedly and miserably.  

COLIN KAEPERNICK.  Unlike his namesame Kopernikus, Kaepernick likely believes the Solar System, and indeed, the entire Universe, revolves around the Super Bowl.  Gravity is held in force by a number of Super Balls with a coefficient of elasticity of .92 which bounce around between planets holding them close to the Super Bowl.  The theory is explained in detail in his tattoos but can be summarized as Super Bowl = Super Ball x mc (squared).


The power outage and interruption of the game for thirty minutes--a longer break than the halftime--and wasn't Beyonce really good--along with Destiny's Child?  really gave the 49ers a chance to catch their breath, their wind and their second wind.

BEYONCE DELIVERED AN AMAZING HALFTIME SHOW.  SHE DOES NOT APPEAR TO EVER SUFFER FROM AN ENERGY SHORTAGE.  SHE ALSO REUNIFIED WITH DESTINY'S CHILD.  NOT ONLY BOOTYLICIOUS, BUT SINGLE LADIES, PUT A RING ON IT.  BE A MAN ABOUT IT.  PUT A RING ON HER IF YOU'RE SERIOUS.  And seriously, never, ever, bring back the Black Eyed Peas ever again.  Please.


The result was a furious comeback by a now rested 49ers team that very nearly stole Ray Lewis and Joe Flacco their glorious moment of triumph.  The Niners stormed to several scores, and would have taken over the game but for several key stops by the Ravens' stellar defense, including stopping the Niners for a FG on one drive and stopping them at the last in a goal line stand with the game on the line, four downs and out with first and goal at the five yard line, a goal line stand that will live in Super Bowl (and Ray Lewis) glory.  

NIKOLAUS KOPERNIKUS, FAMED ASTRONOMER.  He theorized the solar system revolved around the sun and therefore reaffirmed the heliocentric theories of Aristarachos of Samos of antiquity, which had been rejected by Ptolemy in favor of a system in which everything revolved around the Earth.  Ptolemy was Church-approved doctrine.


At 34-31, it was a glorious and magnificent game, and very similar to the glorious Pittsburgh-Dallas Super Bowl XIII played at the Orange Bowl in Miami in 1979, where Terry Bradshaw and the Steelers edged Dallas and Roger Staubach in the game, 35-31.  

SUPER BOWL XIII 1979 THE STEELERS BEAT THE COWBOYS 35-31 IN A GAME REMARKABLY SIMILAR TO THE ONE JUST PLAYED BETWEEN BALTIMORE AND SAN FRANCISCO.  THE STEEL CURTAIN OF PITTSBURGH AND THE AMAZING DEFENSE OF BALTIMORE AND RAY LEWIS HAVE WON SIX SUPER BOWLS BETWEEN THEM.  THEY ALSO SAID TERRY BRADSHAW COULDN'T PLAY QB.  LIKE JOE FLACCO, ALL HE DID WAS WIN, BABY.


The HOFers who played or coached in that Super Bowl?  How about SEVENTEEN!    Start with coaches Tom Landry for the 'Boyz and Chuck Noll for the Steel Curtain.  For the Cowboys, Roger Staubach QB, Tony Dorsett RB, Jackie Smith TE, Randy White Defense, Rayfield Wright.  On the Pittsburgh side of the ledger, Terry Bradshaw, Mean Joe Greene, Franco Harris, Jack Ham, Jack Lambert, John Stallworth, Lynn Swann, Mike Webster and Mel Blount.  

It may well be that one day both Jim and John Harbaugh will be in the HOF, and we already know Ray Lewis has a chair waiting for him in Canton, OH.  Frank Gore, yes.  Several other Niners have shots.  Andre Reed and Ray Rice may get their turn, and several others in the Baltimore Defense.  

A special shout out to Michael Oher, whose life story inspired "The Blind Side".  He was on the Ravens, and now from Ole Miss to the Super Bowl.  Could a sequel be in the works?  Please make a sequel.

MICHAEL OHER, the actual player who inspired THE BLIND SIDE, plays for the  Baltimore Ravens and has won a Super Bowl championship.  If you're going to have a movie mom from Ole Miss, it surely should be Sandra Bullock.


Joe Flacco, you are the pride of Little Audubon NJ, and the pride of the University of Delaware Blue Hens, whose football coach Tubby Raymond was one of the greatest.  You made us all proud. In the great tradition of Rich Gannon, you showed America that QBs from small schools can compete on the NFL's biggest stage with the QBs from big schools and big conferences, and that heart is as important as money and talent.  He's just average Joe, from Delaware and Jersey, like our own VP, Joe Biden, of Delaware and Scranton.  You have to like them.

UNIVERSITY OF DELAWARE FIGHTING BLUE HENS


Bernard Pierce of Temple, of the Ravens, who was a key element of the Ravens' success as a rookie.  We saw him rush for like 250 yards in a Temple game a couple of years back, and he was the entire Temple offense.  Temple was going 8-3, 7-4 and making bowl games with Pierce.  That's how good he was--he dragged a very average program into the stratosphere.  They beat Buffalo in the game we saw at the Linc something like 45-0 and Pierce just ran wild all the day long.  We're not suprised to see Bernard Pierce succeed in the NFL.  He's like Brian Westbrook, only better.  Kudoes to Bernard Pierce.  

BERNARD PIERCE OF TEMPLE RUSHES FOR AMAZING AMOUNTS OF YARDS WHILE PLAYING FOR TEMPLE FOOTBALL.  HE PLAYED A KEY ROLE FOR THE BALTIMORE RAVENS AND NOW HAS A RING.


Finally, here's to the Harbaugh brothers.  Jim and John, you honored us all.  Someone had to lose, but in victory and in defeat, both of you were honorable and exemplary, and most of all, you brought honor to your family of a kind that was unbelievable.

FRED SHERO, LEGENDARY PHILADELPHIA FLYERS COACH.  "IF YOU HAVE BACON AND EGGS FOR BREAKFAST, THE CHICKEN IS MAKING A CONTRIBUTION, BUT THE PIG IS MAKING A COMMITMENT"  VOTED THE GREATEST COACH IN PHILADELPHIA SPORTS HISTORY BY THE PHILLY DAILY NEWS 1999.
  


Ray Lewis, we give you the words the late Fred Shero, aka Freddie "the Fog" Shero, legendary coach of the Stanley Cup Champion Philadelphia Flyers, wrote on the chalkboard before the Flyers went out and beat the Boston Bruins as huge underdogs in Game Six of the Stanley Cup Finals in 1974.

WIN TODAY AND WE WILL WALK TOGETHER FOREVER.

Ray Lewis and the Ravens--CHAMPIONS.

NFC & AFC Title Game Predictions for Sunday January 20, 2013

NFC & AFC Title Game Predictions for Sunday January 20, 2013

Well, we're down to the "final four" of our annual NFL Super Bowl tournament.  

Last Week's Picks

We did very, very well again with last week's picks--we picked every game correctly, and only missed the Denver-Baltimore game, which was decided by a FG in a second overtime, 38-35.  But for the Baltimore upset, we would have been 4 for 4.

Taking the prior weekend's picks into account, we are 6 for 8 or batting .750.  Not too shabby.  

The Super Bowl was Named for the Wham-O "Super Ball".  See Discussion, Below.  I had one of these when I was a kid. As you can plainly see, SuperBalls were made of "amazing Zectron".  


Before we get to Denver-Baltimore, let's go over the other games.  SF-Green Bay played out like we saw it in the first half, a very close game.  In the second half, Green Bay seemed to play tired, like a team coming off a wild card round, while SF seemed like the rested team they were, and SF steadily pulled away in the second half.  While it was surprising that QB Aaron Rodgers did not provide more offense in the 2d half, it's also true that he was slightly missing on some throws while SF seemed to make all the big plays.  Again, fatigue has to play a role in things like that, and Rodgers, for Green Bay to win, has to toss it up there @50 times a game.    

The Seahawks-Falcons game also played out like we thought through @ 2 1/2 quarters, with the Falcons in firm control and up twenty points.  Then, the Seahawks, as with last week, mounted a furious comeback, eventually taking the lead 28-27 with less than a minute to go.  This again shows how evenly matched those teams were,and how very good a coach Pete Carroll is--his team never quit, even though they were on the road and they were tired.  You had to love the way Seattle played.  But even better was the way Atlanta responded--by going fifty yards in less than 20 seconds and then kicking the GW FG--showing that Matt Ryan's experience--something we touted last week--together with the home field advantage--kicking in a dome is FG friendly--would prove very helpful to the Falcons when it came down to it.  So we got that one right.  Barely, but right.

Finally, we got the Pats-Texans game exactly right.  The Texans are a fine team, but they can't keep up with the Pats' offense, and they can't hold them defensively.  That was not even a close game, and we didn't think it would be, so we picked that one correctly and for the right reasons.  

So where did we go wrong with Denver?  What is the lesson?  Never pick Peyton Manning against Ray Lewis in a playoff game?  Well actually Peyton Manning was 2-0 vs Baltimore in prior playoff games.   

Here's a stat worth considering:  Jake the Snake Plummer and Tim Tebow each have more playoff wins in a Denver Broncos jersey as starting QBs, than Peyton Manning.  This has to be embarassing to Peyton Manning, whose little brother Eli Manning of the NY Giants has two Super Bowl wins against the NE Pats on his resume to Peyton's one win in the Super Bowl.

Well, we said Ray Lewis was a warrior, and in the end, the Baltimore Defense made Peyton Manning look awful.  They won the game by forcing him to roll right in OT, and make a terrible off balance throw that resulted in an interception, a throw that Peyton Manning never makes, normally speaking.  This results in an INT, Baltimore gets the ball, goes down and kicks the GW FG, game over.  

This is really the story.  

PREDICTIONS FOR AFC CHAMPIONSHIP AND NFC CHAMPIONSHIP THIS WEEKEND


Ravens at Pats 3 PM Sunday AFC Championship

First, we have the Baltimore Ravens at the New England Patriots in the early game, scheduled for 3 pm in New England, in a rematch of last years AFC title game.  There are three games we can look at here.

Initially, we have this years game between the two teams, which the Ravens won 31-30 on a GW FG as time expired, in week 3 of the season, back in September, in Baltimore.  The Baltimore defense essentially held Brady in check while Flacco & the Baltimore offense scored 10 unanswered points in the last five minutes of the game to beat the Pats.  Strong stuff.  

Second, you have last years AFC championship game, which the Pats won 23-20.   However, as everyone knows, Baltimore had a chip shot FG to tie, which Billy Cundiff missed with barely any time left on the clock, and Baltimore had numerous other opportunities in the 4th Quarter to come back from a 23-20 deficit.  The Pats were very lucky to escape out of that game as victors.  

Third, you have the 2009 wild card round game, wherein Baltimore came into New England and soundly whipped them, 33-14.  

Baltimore is the one team in the AFC that really gives Tom Brady trouble.  

Baltimore will be motivated to win because they lost last year, because Ray Lewis is looking at his last year, and because they know they can beat this New England team.  

On paper, this matchup strongly favors the Patriots, and they are at home, but the pick here is the Ravens in an upset.  

Ray Lewis is going to the Super Bowl.  

49ers at Falcons - NFC Championship

This is a very closely matched game on the stats.  Common opponents don't really say much--the 49ers beat the Saints, while the Falcons split with the Saints, winning one and losing one.  The 49ers split with the Seahawks, winning one and losing one, while the Falcons hung on to beat the Seahawks in the playoff game this past weekend.  All this tells us is that both teams can play against very good opponents like the Seahawks and Saints and beat them on a given day.  It also tells us on any given Sunday either of them might lose to the Saints or the Seahawks, which we probably already knew, and therefore, there's no 100% probability that if these guys played three games, one team would sweep all three--much more likely that there would be a split and then a deciding game.  

However, they only play one, and in this one, we pick the 49ers. The Falcons have much going for them--the home field, Matt Ryan being due, and Atlanta being ripe for a trip to the Super Bowl.  But on the other side you have a very tough SF 49er team, which features the rushing attack of one day HOFer Frank Gore (U. Miami Hurricane), who is 3d among career RBs in career rushing, just behind Adrian Peterson and both trailing Steven Jackson.  Gore is supplemented by a running QB in Colin Kaepernick, and a fervent defense.  

David Akers, who is a veteran kicker, should be an advantage, but he presents some weakness from beyond 40 yards, especially compared to Atlanta's kicker Bryant.  If it comes down to FGs, there is an edge somewhat to Atlanta, though the dome will help both kickers.    The pick is still the 49ers.  

Postscript

We mentioned great RBs last week--but we forget to mention Emmitt Smith and Tony Dorsett among the greatest ever.  Smith is obviously among the greatest RBs ever to play the game, and a true champion, while Tony Dorsett, also a Dallas Cowboy great, could also do it all.  Both were great rushing as well as receiving, and both were durable and versatible backs who were at their best in the playoffs and in the biggest games.  No one could possible leave them off their teams.  Another mention has to be made of Franco Harris, the powerful and durable back of the Steelers dynasty of the 1970s.  

We were once (several of us) at a Penn-Princeton football game  many years back and sitting right in front of us, was Franco Harris, who was watching his son with the Princetonians.  He looked pretty much as he did during his playing days, and on his fingers were the four Super Bowl rings--quite a sight, mind you.  

We were not worthy.  

In fairness, you'd want a Franco Harris or an Emmitt Smith or a Tony Dorsett on your team any day of the week.  They were winners, and I can't count how many Super Bowls, Conference Championships, playoff games, they all won  collectively, but it has to be a ton.  

The Name of the Super Bowl Derived from the Wham-O Super Ball, as Shown by This Exhibit in the Pro Football HOF in Canton, OH.  The fact that Lamar Hunt coined the name is recited therein.  The owners had decided to call it the "AFL-NFL Championship Game".  Well, you see how well that worked.  No .92 resiliency coefficient.  "After watching his children play with a Super Ball, Lamar Hunt, founder of the American Football League, coined the term Super Bowl. In a July 25, 1966, letter to NFL commissioner Pete Rozelle, Hunt wrote, "I have kiddingly called it the 'Super Bowl,' which obviously can be improved upon." Although the leagues' owners decided on the name "AFL-NFL Championship Game," the media immediately picked up on Hunt's "Super Bowl" name, which would become official beginning with the third annual game.[8][17][18]"  http://en.wikipedia.org/wiki/Super_Ball


Final PS point:  

The Super Bowl was named after the Wham-O toy, the "Super Ball"

It's true.  Lamar Hunt and his fellow owners were sitting around one day figuring out what to call the new championship game back in the mid-60s and they got the name from the "Super" of "Super Ball".  It's told right here at: http://sports.yahoo.com/nfl/blog/shutdown_corner/post/Is-the-Super-Bowl-really-named-after-a-1960s-chi?urn=nfl-317028.

Here's the Yahoo article: 

"Is the Super Bowl Really Named After a Children's Toy?"
It seems too much like an urban legend to be true that the Super Bowl was named after a children's novelty toy that was popular in the mid-1960s.
But strange as it sounds, it is. The name of America's biggest sport event got its name from a Wham-O toy called "Super Ball." The story was recounted in Michael MacCambridge's book, "America's Game."
Once the NFL-AFL merger was announced, discussions began about the inaugural championship game between the winners of the two leagues. A group of seven men were tasked with the specifics. During the course of the meetings, it became confusing when the men referred to "the championship game" because the others didn't know whether he was referring to the league championship games or the finale, which still didn't have a name. To end the mix-ups, Kansas City Chiefs founder Lamar Hunt jokingly referred to the final championship game as the "Super Bowl." He had come up with the name while watching his children play with the toy pictured above.
"Super Bowl" is how the game was referred to for months, even though Hunt himself said it was "far too corny" to ever be used on the big stage. In the middle of 1966, he wrote commissioner Pete Rozelle and said the group needed to come up with an official name for the game. "If possible," he wrote, "I believe we should 'coin a phrase' for the Championship Game. [...] I have kiddingly called it the 'Super Bowl,' which obviously can be improved upon."
Rozelle agreed. The league's publicity director recalled that the commissioner despised the word "super," because it didn't have any sophistication. Rozelle was evidently a "stickler on words and grammar." The game would be known as the "AFL-NFL World Championship Game."
That bulky title didn't last. People caught wind of Hunt's name and soon everyone, from media members to players, were calling the title game "the Super Bowl." The NFL was slow to adapt, though. It wasn't until the third game that the words "Super Bowl" appeared on the official game program and the fourth game when the phrase appeared on tickets.
As mentioned above, Michael MacCambridge's excellent "America's Game: The Epic Story of How Pro Football Captured a Nation" was the main reference for this blog post.

The Original Patent for the SuperBall aka "Highly Resilient Polybutadiene Ball" Patented by Wham-O Corp 1965.

3,241,834
HIGHLY RESELIENT POLYBUTADIENE BALL 
Norman H. Stingley, Garden Grove, Calif., assignor to
Wham-0 Manufacturing Company, San Gabriel, Calif.,
at corporation of California
Filed Aug. 25, 1965, Ser. No. 432,584
3 Claims. (Cl. 273--58)
This is a continuation-in-part of application Serial No. 462,081 filed June 7, 1965, and now abandoned.
This invention relates to a toy and more particularly to a ball or sphere having extremely high resilience and a high coeflicient of friction.
The resiliency of rubber balls is one of their most important characteristics. This is because the resiliency of the ball material determines the “liveliness” and “bounce” of the ball and hence its utility in various sporting games and attractiveness as a toy for children. The resilient material normally used for making rubber balls is a polymer such as natural rubber or some synthetic analog of natural rubber such as polyisoprene.
The present invention is concerned with a material other than rubber and -polyisoprene as the base polymer in rubber toys and sporting articles. It has been found that this new material imparts some highly unusual qualities to articles fabricated with it. Such articles have been found to have a substantially greater resiliency than those manufactured from more conventional materials. This greater resiliency is thought to be due to the nature of the base polymer used in the mixture and the unique quality -of the mixture which comprises the article of being able to conserve the energy which is imparted to it rather than dissipating a substantial portion of it in the form of heat. The higher resilience means that balls made from the material of this invention have a resilience factor in excess of 90%. This resilience factor is the resilience of the material as measured by the Yerzley method, ASTM D945-59.
Another unusual quality of balls and toys of this invention is their coeflicient of friction. In this instance the coefficient friction is substantially higher than in other
similar items. This quality combined with the significant
ly higher resilience causes a ball to react in an extraordinary and unpredictable manner when bounced or struck. This higher coeflicient of friction also provides a means whereby the spin or “English” on a thrown, struck or dropped ball can be accentuated resulting in unusual reactions by -theball whenever it rebounds from a hard surface. This novel combination of qualities means that one natural application for ‘balls manufactured with the base polymer with which this invention is concerned is in trick ball uses. In addition, as a sports implement a ball of this invention presents -a greater challenge -to the user. As an article of play, the eccentricity of reaction makes the ball highly entertaining and amusing toy.
The invention in the present case contemplates a molded, vulcanized, highly resilient ball comprising a mixture of polybutadiene, a sulfurous vulcanizing agent and a polybutadiene reinforcing agent.
In addition to the inherent resilience of the base polymer, the degree of cross linkage between -polymer chains is important in optimizing the bounce or liveliness of balls fabricated with it. The -degree of cross linkage is primarily determined by the amount of vulcanizing agent used. By limiting the amount of vulcanizing agent introduced into the mixture to the quantities specified below, a ball having a Yerzley resilience in excess of 90% is obtained. Such a resilience factor is substantially higher than that found in balls manufactured from natural rubber or polyisoprene.
In addition to resilience and cross linkage, the ability

In the formulation above polybutadiene is the base polymer of the mixture. To produce cross linkage between polybutadiene chains, that is, to vulcanize or cure the polymer, sulfur is added to the mixture. A greater amount of vulcanizing agent is used in this mixture than in such products as tires thereby producing a greater degree of vulcanization. Put another way, the degree of cross linkage relative -to saturation (hard rubber) is increased over tires and the like. The more complete vulcanization is believed to result in the improved resilience of the finished product. The addition of sulfur in the range indicated will result in balls having a Yerzley Resilience in excess of 90%. Oil extended polybutadiene having as much as 50 parts by weight of oil per hundred parts by weight of polybutadiene can also be used as the base polymer.
Because the natural curing rate of a mixture of polybutadiene and sulfur is quite slow, certain other additives are combined with this basic mixture to initiate the curing cycle and accelerate the rate of vulcanization. The zinc oxide and stearic acid are added to the basic mixture to provide this activation function. Acceleration accomplishes two purposes, one, it shortens the length of the molding cycle, and two, it equalizes heat throughout the mixture during the curing cycle. In the preceding formulation, the accelerators are N-oxydiethylene benzothiazole 2 sulfenamide, di-orthotolylguanidine and bismuth dimethyldithiocarbonate. For ease of reference, the trade names AMAX, DOTG and Bismate respectively will be used to designate the accelerators.
The activation of these accelerators occurs as the mixture reaches a specific temperature. For Bismate and DOTG the activation temperature is approximately 230° F. while that of AMAX is -approximately 260° F. By insuring that t-he heat of reaction is equalized throughout the mixture a more uniform rate of vulcanization and improved consistency in the end product is obtained.
Hydrated silica is added to the mixture as a filler. A specific hydrated silica suitable for use in this mixture is marketed under the trademark Hi-Sil 233. This material and certain other materials perform the function of providing tear and abrasion resistance. The basic criteria for selection of the filler material is its ability to improve the durability of polybutadiene without unduly increasing the specific gravity. Carbon black and lithium oxide have also been found to fill these requirements and are satisfactory substitutes for the hydrated silica.

In addition to the ingredients just previously discussed, 4 methyl-6 tertiary-butyl phenol is also added to the mixture. This substance has been given the trade name of Antioxidant 2246 and prevents discoloration and staining and inhibits aging of the finished product. Examples of substitutes for Antioxidant 2246 are phenyl B naphthylamine, alkyl diphenylamine, and hindered alkyl phenols. Pigmenting agents for obtaining the desired color of the end product are optional additives.
The mixture and molding of the constituents of this formulation proceeds according to the following steps. The various elements of the formulation are brought together in a mixing machine and agitated thoroughly to insare uniform mixing and distribution of the elements throughout the mixture. The result is a plastic mass ready for insertion in a mold.
To complete the process, the mixture is placed in a nold and subjected to a pressure of between 500 and 3,000 p.s.i. for a period of approximately 10 to 30 minutes. Simultaneously, the temperature of the mixture is raised to approximately 285-340° F. To a certain extent the length of the molding operation, the pressure, and the temperature to which the formulation is subjected are co-variant and one may be adjusted to compensate for a variation in the other. Preferably the time and temperature for the molding operation is 15 to 20 minutes at approximately 320° F. and 1,000 p.s.i.
An alternate formulation to the one outlined above is as follows:
[graphic][graphic][merged small][graphic][graphic]
The above formulation is mixed in the same manner as the preceding formulation. To insure a good dispersion of all ingredients in the mixture, the batch is normally given a two-pass mix. In the above formulation, the zinc oxide and the stearic acid perform the same functions, viz., activation of polymer curing, as they did in the first formulation. Akron 544 Red and Akron 626 Blue are trade designations for organic coloring agents manufactured by Akron Chemical Co. Titanium dioxide is also a coloring agent. These three constituents in combination are the pigmenting agent for the mixture.
Zeolex is a proprietary brand name for a series of precipitated, highly hydrated sodium silico-aluminates and sodium calcium silico-aluminates. Its function is to strengthen the finished product and to act as a filler in the same manner as the Hi-Sil 233 does in the preceding formulation.
Sulfur is the vulcanizing agent. Vandex is a proprietary name for finely ground selenium. Its function is to supplement sulfur as a vulcanizing agent.
As in the first formulation, several constituents of the mixture (AMAX and M. Tuads) are added to serve as accelerators for the polymerization.

As is normal in molding tehniques, the curing temperature must be carefully selected in order to prevent imperfections in the finished product. Too high a molding temperature will contribute to a condition designated “backrind.” This condition is characterized by an indented fracture around the body of the molded product defining the point where the two halves of the mold are brought together and is due to thermal expansion in this area during and after the molding cycle.
Subject to the proper choice of injection pressure, injection time, and the combination of mixture constituents, preheat, and mold temperature, this mixture can also be molded by means of a conventional injection-molding technique.
Combinations of ingredients of which the two formulations listed above are representative have been found to result in a product with a specific gravity of approximately 1.0 to 1.3. For greatest resilience, it has been found that a sufficient amount of filler should be added to produce a product having a specific gravity of 1.02.
What is claimed is:
1. A highly resilient solid ball in the form of a sphere, the ball material having a specific gravity of from about 1 to about 1.3, and comprising in combination a vulcanized polymer characterized by the use of 100 parts by weight of polybutadiene and 0.5 to 15 parts by weight of a sulfur vulcanizing agent, and further comprising, in addition to any activators and accelerators used for vulcanization, 5 to 15 parts by weight of an inorganic reinforcing material.
2. A ball in accordance with claim 1 in which the reinforcing material is selected from the class consisting of hydrated silica, carbon black and lithium oxide.
3. A ball in accordance with claim 2 in which the sul
' fur vulcanizing agent is approximately 5.25 parts by
weight and the reinforcing material is approximately 7.5 parts by weight.
