Abstract: An antistatic polyester polyurethane foam containing substantially uniformly incorporated therein as an antistatic material a combination of a particulate, electrically conductive material, such as carbon black, and a haloacetic acid, such as dichloroacetic acid. The combination of conductive material and haloacetic acid which is incorporated into the polyurethane foam during its in situ preparation is believed to be tied into the foam through reaction of the haloacetic acid and at least the diisocyanate used in the foam formulation. The polyurethane foams of this invention have excellent antistatic properties while retaining the desirable features of a good polyurethane foam including uniformity of cell size, no pinholing, and good structural stability.

Abstract: Polyurethane foams having a particulate resin carrying a fragrance incorporated therein during formation of the foam are described. The physical characteristics of the foams are not detrimentally affected by the incorporation of the resin while providing a foam which will release fragrance over an extended time period.

Abstract: An improved method for manufacturing a foam-filled polyurethane foam bun from foam particles having uniformly dispersed therewith large amounts of solid material bonded together with new polyurethane foam is described. The method comprises uniformly applying a liquid flexible polyurethane foam-forming material to a dispersion of foam particles and solid material to provide a blend, distributing the blend within a mold, and foaming and curing the foam-forming material by a plurality of steaming steps wherein the mold is flipped from a first to second position between steaming steps. The foam buns have a uniform density gradient. Foam buns are disclosed having a variation in density across the foam bun. There is also disclosed an improved char-forming foam obtained as a result of using boric acid in the foam-forming formulation.

Abstract: Flame retardant, char-forming, flexible polyurethane foams are described which include, in addition to suitable diisocyanates and other basic foam-forming components, a flame retardant material and a polyol which has substantially non-reactive hydroxyl groups with respect to the diisocyanate component under the conditions of the foam-forming reaction. Accordingly, the polyol remains in the finished polyurethane foam substantially unreacted. When the finished foam product is subjected to combustion conditions the flame retardant material and unreacted polyol combine to retard flame formation and to provide a dripless char. In addition to the flame retardant and char-forming characteristics, the flexible polyurethane foam is firm, permitting the manufacture of clickable foams.

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.
