摘要： Improved tennis racket in which an inverted chevron shaped yoke is provided having downward sloping side portions which match the curvature of the arcuate top portion of the racket head to provide vertical strings extending between the yoke and arcuate top portion which are of the same length. The equal length of vertical strings provide uniform elastic response to ball impact. The particular design of the chevron provides added structural strength to the neck of the racket. An improved racket made from a polycrystalline metal oxide fiber and resin matrix is also disclosed. In addition, an improved string protection system involving elastomer inserts which are molded into the head portion of composite material rackets is described.

摘要： A skip rope for exercise and fitness conditioning includes a length of polypropylene rope threaded through two handle members disposed at opposite ends of the length of rope. After the rope is threaded through each handle member, the free ends of the rope are knotted to prevent it from pulling back through the two handles. Each handle is constructed of a tubular section of polyvinylchloride which has nylon end plugs press fit into the open ends of the tube. The outside diameter surface of each end plug coincides with the outside diameter surface of the polyvinylchloride tubing and each end plug includes a rope-receiving clearance aperture just slightly larger than the outside diameter of the rope. The material combination of nylon for the end plug and polypropylene for the rope provides a type of self-lubricating interface which enables the rope to turn and twist completely independent of the handle. Further, this self-lubricating characteristic enables the rope to slide relative to the end plugs without wear or abrasion to any significant degree.
摘要翻译：用于运动和健身调理的跳绳包括穿过设置在绳索长度的相对端处的两个手柄部件的一长度的聚丙烯绳索。在绳索穿过每个手柄部件之后，绳索的自由端打结以防止绳索通过两个把手拉回。每个手柄由聚氯乙烯的管状部分构成，其具有压配合到管的开口端的尼龙端塞。每个端塞的外径表面与聚氯乙烯管的外径表面重合，并且每个端塞包括稍大于绳的外径的绳索接收间隙孔。用于端塞的尼龙和用于绳索的聚丙烯的材料组合提供了一种自润滑界面，其使得绳索能够完全独立于手柄转动和扭转。此外，这种自润滑特性使得绳索相对于端塞没有磨损或任何显着的程度滑动。

摘要： Prepolymerized resins are applied to wooden articles to coat them and impart a tough and abrasive resistant surface which protects the articles from deterioration and delamination due to shock, impact and abrasive forces. The resins are applied by contacting the articles with a prepolymerized resin which has been dissolved in a readily vaporizable solvent to form a resin solution, coating the article with the resin solution, vaporizing the solvent from the resin coating and drying the resin coating. The coated articles find particular utility in high shock and impact uses such as hockey stick blades.

摘要： A hockey stick is made as a unitary, injection molded product from foamed nylon mixed with glass fibre. The use of foamed nylon results in a relatively lense shell on surface and a core having reduced density. There are no cavities in the stick such as in known hockey sticks or the like made of plastic material. The stick maintains its shape after molding due to a relatively low stress caused by molding pressure which is low in comparison with that required in the production of known plastic hockey sticks. The stick is generally identical to a regular wooden stick from the standpoint of weight and that of weight distribution. An embodiment of the stick with aluminum reinforcement of its blade portion is also disclosed.
摘要翻译：曲棍球棒是由与玻璃纤维混合的发泡尼龙制成的整体注塑产品。使用发泡尼龙导致表面上相对较强的外壳和密度降低的芯。在棒中没有空腔，例如在由塑料材料制成的已知的曲棍球棒或类似物中。由于与生产已知的塑料曲棍球棒所需的成型压力相比较低的成型压力引起的相对低的应力，棒材在模制之后保持其形状。从重量和重量分布的观点来看，棒通常与普通木棍相同。还公开了其刀片部分具有铝加强件的棒的实施例。

摘要： Apparatus for decelerating bowling balls on ball return track systems by snubbing them with the aid of resilient leather belts under tension are widely used. The invention disclosed herein is of an improved apparatus for use in decelerating bowling balls on ball return track systems. The improvement comprises employing as the belt component, a resilient but stiff belt fabricated to offer greater frictional surface than prior art belts and having an inside arc smaller than the arc defined by the balls to be snubbed, thereby to grip the moving balls in a pincer-like grip. The improved apparatus of the invention is more efficient, requires less maintenance, has a longer life and offers economic advantages over prior art devices.
