Abstract: A refreshment rack is constructed of structural material formed into a stable base having an inclined planar rod loop extending from the base. The rod loop defines an opening for inserting a long, narrow neck bottle, as in a wine bottle, and supporting the bottle essentially horizontally in cantilever fashion upon release. The base is adapted to receive a plurality of service trays for food that compliments the bottled beverage. The rack also includes a plurality of drinkware holders for holding beverage-related drinkware.

Abstract: A combination visual aid and protective device for use on the string end of a game racquet frame, the device being constructed of a thin, light-weight, brightly colored vinyl material that is predisposed to assume an arcuate shape that intimately conforms to the complex curved surface of the game racquet frame, in a manner to prevent the device from slipping relative to the frame.The device includes a plurality of stress relief holes that function to permit the device to conform to the racquet frame surface and to reduce its weight as much as possible.The visual aid and protective device is attached to the string end of the game racquet frame by a plurality of plastic coated wire-like attachment devices having generally rectangular cross-sections.

Abstract: A load-responsive variable diameter pulley in a drive system using a driving pulley and a driven pulley functionally connected by a belt. The basic pulley assembly includes two spaced apart parallel sideplates concentric to a hub. One plate is fixed to the hub while the other is movable angularly about the pulley axis relative to the fixed plate. Slots are provided in the surfaces of both plates and a plurality of arcuate belt-engaging segments located between the plates are provided with laterally extending pins that are received in the slots. In the basic pulley a spring normally urges the movable plate to bias it and belt-engaging segments to the position defining maximum pulley diameter. The slots in the fixed plates are in pairs and the individual slots are not parallel to each other. The slots are designed so that the chord of the effective arc of the arcuate segment guided in the slots is always perpendicular to a radius of the pulley.
