Patent number: 5664774Abstract: A softball has a high end synthetic leather stitched cover formed from a low density non-woven fiber mat impregnated with polyurethane. The softball, which can be formed to meet association specifications, has a circumference of 11 or 12 inches and a cover to core weight ratio significantly less than 0.1, typically in the range of 0.08-0.16, while meeting durability requirements. The cover preferably has a thickness of 0.045-0.065 inches. Because a greater weight concentration is in the core of the ball, the ball has improved playability characteristics over conventional balls having heavier synthetic leather covers, while exhibiting a sound comparable to that of a leather covered softball when struck with a bat.Type: GrantFiled: December 15, 1995Date of Patent: September 9, 1997Assignee: Lisco, Inc.Inventors: Alan D. Walker, John Uaszek

Patent number: 5647590Abstract: A game ball having a softer core and abrasion resistant cover is particularly well suited for play on hard pavements and cement in inner city areas. The ball has a polyurethane foam core formed from a mixture of 100 parts polyol and 33-40 parts isocyanate. The core has a compression of 0.06-0.07 inches when subjected to a force of 10 lbs. and a coefficient of restitution at 88 feet per second of less than 0.45, and preferably 0.30-0.40. A molded polyvinyl chloride plastisol cover is formed over the core, resulting in a game ball for which the ratio of the coefficient of restitution of the ball to the coefficient of restitution of the core is in the range of about 0.90-0.99. The cover preferably is a durable molded cover having a Shore A hardness of about 60-70 and a tensile strength of about 1,400-1,800 psi. The ball of the invention has restricted flight characteristics and is particularly well suited for use on smaller ball fields.Type: GrantFiled: November 21, 1994Date of Patent: July 15, 1997Assignee: Lisco, Inc.Inventors: Alan D. Walker, Ron LaLiberty

Patent number: 5423088Abstract: An improved game glove including a front portion and a back portion defining a hand space therebetween and forming a major region for receiving the fingers of the wearer and a minor region for receiving the thumb of the wearer; an opening at one edge of the glove for the passage of the hand of a wearer into the hand space; a bladder positioned in the hand space, the bladder having a major portion in the major region of the glove and a minor portion in the minor region for the glove; and an inflation system to selectively inflate the bladder the inflation system including a pump system having a diaphragm for selectively inflating the bladder to improve the fit of the glove on a wearer's hand, the pump system also including a tube coupling the diaphragm and the bladder.Type: GrantFiled: October 1, 1992Date of Patent: June 13, 1995Assignee: Lisco, Inc.Inventors: Alan D. Walker, David P. Chastain, Harvey A. Koselka, Andrew Jones

Patent number: 5091265Abstract: A coating composition for game balls, such as baseballs and softballs, is provided. The coating composition is comprised of a specific film-forming binder system, a fluorescent pigment, at least one compatible solvent and additional components including texturizing and leveling agents. The various constituents of the coating composition are combined together in predetermined, relative proportions to produce a composition which, when applied to a game ball such as a softball, provides a coating having qualities including a bright fluorescent color, excellent durability and weather resistance, as well as a soft leathery texture.Type: GrantFiled: February 19, 1991Date of Patent: February 25, 1992Assignee: Lisco, Inc.Inventors: Thomas J. Kennedy, Alan D. Walker

Patent number: 4416225Abstract: The invention provides an internal combustion engine, such as a diesel engine, set to run on an emulsion of fuel and water, supplied to an emulsifier through separate fuel and water lines. The water feed preferably is under gravity, and the water line has a metering orifice to control the flow of water. If the engine is provided with emulsion overspill, this is returned through a return line for the overspilled emulsion, and said return line has a surge tank with a vent enabling the venting of air and/or the breaking of vacuum in the return line.Type: GrantFiled: August 7, 1981Date of Patent: November 22, 1983Assignees: Albert Constantine, Cadbury Schweppes Transport Services Ltd.Inventors: Albert B.
