1	Long life, low air permeable pressurized articles such as play balls	US438674	1995-05-10	US5593157A	1997-01-14	William J. Koros; I. G. Hargis; Richard A. Olson; Jason S. Harris
Low air permeable, pressurized articles such as play balls, e.g., a tennis ball, have a thin barrier layer formed on the vulcanized rubber core. The barrier layer is chemically bonded to the internal and/or external surface of the core, e.g., by the reaction of a Lewis acid, e.g., sulfur trioxide, with the core rubber. The thin barrier layer permits the tennis ball to be flexible and have good rebound life and yet extends the play life thereof before ball rebound or softness changes to undesired levels.
2	Elastic spheroid structure	US15379644	2016-12-15	US09855468B1	2018-01-02	Sheng-Mou Huang
An elastic spheroid structure includes a hollow elastic spheroid body having an elastic spheroid shell, a receiving space formed inside the elastic spheroid shell, and a through opening passing through the elastic spheroid shell and being in air communication with the receiving space. The through opening has a first predetermined shape, the through opening has a first middle portion and a plurality of first extending portions extended outwardly from the first middle portion, and the first predetermined shape of the through opening is formed by connecting the first middle portion and the first extending portions. The elastic spheroid structure further includes a solid elastic cover body disposed inside the through opening of the hollow elastic spheroid body and a connection layer disposed inside the through opening and connected between the elastic spheroid shell and the solid elastic cover body.
3	DPS Sport Ball	US15159899	2016-05-20	US20170304685A1	2017-10-26	Jahangir Iqbal
A DPS (dual pressure system) sport ball incorporating a special, environment friendly casing that forms an exterior surface of the ball, which is bonded to a multiple lining layers to form a laminated sheet. The laminated sheet is sized, printed, and cut out into specifically designed panels using highly optimized and automated specifically developed machines. The panel cut outs are stitched together using a special stitching machine and a specific, compatible bladder is incorporated in the ball. The partially machine stitched ball is then finally closed by manual stitching and the seams are protected with a special adhesive. Resultantly, due to unique construction materials, their unique arrangement, innovative technology, and highly automated manufacturing processes, the DPS sport ball has advantageous durability, playability, controllability and excellent flight characteristics. The DPS sport ball qualifies under the international standards of match/professional balls at a very competitive price.
4	Golf ball	US3637220D	1968-10-30	US3637220A	1972-01-25	FRALEY THOMAS E
A game ball such as a baseball, tennis ball or golf ball containing an impact-responsive explosive charge. Upon being struck by a bat, racket or club, the ball is somewhat deformed and the impact energizes the explosive charge which instantaneously generates internal pressure within the ball. The internal pressure causes the deformed ball to instantly resume its initial shape against the impacting club, thus assisting in imparting a propelling force to the ball. The ball remains internally pressurized after the first impact and the benefits of its pressurization are thus available for subsequent uses.

6	DRUCKGEFÜLLTER TENNISBALL	EP93914698.0	1993-06-23	EP0652793A1	1995-05-17	GIES, Werner; HEITZENRÖDER, Hans-Friedrich
The invention relates to a pressurised tennis ball with a wall consisting essentially of a natural rubber mix. In order to reduce the natural diffusion of the pressurised air inside the ball from the raw ball core, its wall has a thin diffusion blocking layer of a plastic or rubber, the permeability of which to N2 or O2 is lower than that of the natural rubber mixture of the wall.

8	Rubber material for tennis balls	JP26591984	1984-12-17	JPH072865B2	1995-01-18	KIKUCHI MICHITSUGU; YOKOYAMA TOORU

9	Rubber material for gas-filling use	JP26591984	1984-12-17	JPS61143455A	1986-07-01	KIKUCHI MICHITSUGU; YOKOYAMA TORU
PURPOSE:To obtain the titled material capable of effectively preventing gas permeation without having any adverse effect on various rubber characteristics, suitable for tennis balls, etc., by incorporating feedstock rubber with flaky or plate-like filler. CONSTITUTION:The objective material can be obtained by incorporating (A) 100pts by wt of feedstock rubber (e.g., natural rubber, synthetic rubber such as butadiene rubber or isoprene rubber) with (B) 1-150 (pref. 3-80) pts by wt of flaky or plate-like filler (e.g., sericite, kaolin chlorite, aluminum silicate) and (C) as optional ingredients, sulfur, curing accelerator, deterioration inhibitor, dye, etc. Curing of this material under high pressure during molding process will orient the filler (B), the material thus acting as a shielding material preventing gas permeation.
