Abstract: Polyurethane foam products comprising a foam filled with a foam and a large amount of solid material inert to the foam products are described. The foams are prepared by foaming a polyurethane foam-forming diisocyanate and polyol around pre-formed polyurethane foam chips having incorporated therein or therewith solid materials inert to the foam. The inert material can be a fire- or combustion-retardant material; a material such as graphite or the like to render the foam conductive; or a filler material to impart various other characteristics. The polyurethane foam-filled foams can be tailored to have excellent physical characteristics and are particularly suitable for furniture upholstery, cushioning applications including in mattresses, and where special properties are required.

Abstract: Polyurethane foam products comprising a foam filled with a foam and a large amount of combustion retardant materials are described. The foams are prepared by foaming a polyurethane foam-forming diisocyanate and polyol around pre-formed polyurethane foam chips having incorporated therein solid combustion retardant materials. The polyurethane foam-filled foams have excellent physical characteristics and, because of their combustion properties, are particularly suitable for furniture upholstery and cushioning applications including in mattresses.

Abstract: A putter having a soft elastomeric striking face is described. The elastomer of the striking face has a hardness of at least 70 Durometer A and a hardness less than the hardness of a golf ball, and a high resiliency with controlled dampening. This hardness permits penetration of a golf ball into the elastomer when a ball is stroked with the elastomeric face, and the resiliency and controlled dampening causes the stroked ball to rebound from the face at a distance at least as great as the distance of the rebound of the ball when the ball is stroked with an equal force with a metal putter head of equal mass. Additionally, the resilient face imparts to the putter an improved sense of touch and feel without sacrificing distance.In FIGS. 1-5 of the drawing different species of the golf clubs of the present invention are disclosed. In FIG. 1 resilient face 6 extends across the front of the club head; in FIG. 2 the resilient face 6 is partially indented in the club head; in FIGS.

Abstract: Rebonded polyurethane foams having incorporated into the foam urea and/or melamine are described. The rebonded foams have excellent resistance to smoldering combustion and flaming combustion. The rebonded foam is highly suitable, inter alia, for cushioning and seating structures.

Abstract: A lacrosse stick having a tubular metallic handle with knurling at the surface of the handle to provide improvement in grip and handling characteristics under all weather conditions. The metallic handle is preferably of aluminum alloy and elliptical in cross section, with the major axis of the elliptical shape being normal to the general plane of the lacrosse stick head. Dimensions and physical properties of the handle material are interrelated to provide desired balance of the lacrosse stick from the standpoint of handling by players, durability, freedom from failure by fracturing, and standardization in production.

Abstract: Flexible polyurethane foams having low resistance to air flow and, in addition, having good load bearing characteristics and high strength comprising the reaction product of polyisocyanate, a polyol blend including about 40-60 percent by weight of a polyether triol having an average molecular weight of about 4500-6500 and about 60-40 percent by weight of a reinforced polymer polyol having an average molecular weight of about 4500-5500 for the base polyol, and a low molecular weight cross-linking agent, such as 1,4-cyclohexanedimethanol or 4,4' methylene-bis (2-chloroaniline). Preferably the air flow characteristics are improved by crushing the reaction product before it is fully cured.

Abstract: A double-wall, synthetic lacrosse stick including tab means for attachment or formation of the web on the head of the lacrosse stick is described. Preferably the tabs, molded integral with the end and side walls of the head, project inwardly from the extreme upper surface of the walls of the head and are substantially flush with this upper surface. Improved durability and enhanced play characteristics are realized.
