Title: Improvements in and relating to golf balls
Inventor: HARRISON STANLEY RICHARD
IPC: C08K3/26
Filed: 1965-02-10
Abstract: Golf balls comprise a core and a cover for said core formed from a composition comprising a copolymer of at least one mono-olefin and at least one unsaturated mono- or di-carboxylic acid.  The copolymers may be derived from ethylene and acrylic, methacrylic, itaconic, crotonic or sorbic acid.  The copolymers may also comprise units of metal salts of such acids, e.g. sodium or zinc salts, to provide thermolabile cross-linkages; and units of other monomers such as vinyl alkanoates, alkyl acrylates and alkyl methacrylates.  The copolymer may be a random copolymer, or a radiation induced graft polymer of the acid on a polyolefin base. Instead of using an acid salt monomer a cross-linking agent which supplies metal ions, e.g. a metal acetate, oxide, carbonate or hydroxide, may be incorporated. Fillers, e.g. metal oxides, may also be present.  In examples golf ball covers are prepared from compositions comprising (I) ethylene/acrylic acid copolymers and titanium dioxide, with and without zinc oxide; (II) ethylene/acrylic acid/sodium acrylate copolymers and titanium dioxide, with and without zinc oxide; (III) a polyethylene/acrylic acid graft copolymer, with and without zinc oxide; and (IV) an ethylene/methacrylic acid/sodium methacrylate copolymer, or ethylene/acrylic acid copolymers reacted with sodium acetate, and titanium dioxide.ALSO:Golf balls comprise a core and a cover for said core formed from a composition comprising a copolymer of at least one mono olefin and at least one unsaturated mono- or dicarboxylic acid. The copolymers may be derived from ethylene and acrylic, methacrylic, itaconic, crotonic or sorbic acid.  The copolymers may also comprise units of metal salts of such acids, e.g. sodium or zinc salts, to provide thermo-labile cross-linkages; and units of other monomers such as vinyl alkanoates, alkyl acrylates and alkyl methacrylates.

Abstract: 1405333 Air cushions SINGER CO 8 Feb 1973 [9 Feb 1972] 6175/73 Heading A4M [Also in Division B7] A seat for a vehicle simulator comprises a plurality of first inflatable air cells 13 covering the seat pan and back portions of the seat, and a plurality of second inflatable air cells 23 secured to the cells 13 so as to be between them and a seat occupant, and controlled means for inflating the air cells and the cells 23. These latter are pancake air bladders with internal partitions (26), Fig. 3 (not shown), to maintain some stiffness while permitting free air-flow. The cells 13 and 23 are supplied with air, through servovalves 77-80, to simulate the forces on a seat occupant due to acceleration. Thus for an upward acceleration the cells 13 are deflated, so that the occupant sinks into the seat, but the air supply to the cells 23 is increased so that the occupant feels the seat become harder. At the same time lap belt 19 and harness 21 are slackened by pistons 81, 83. Alternatively there may be rigid boards 85 between the air cells 13 of the seat pan and the cells 23, hardness of the seat then being increased by decreasing the air supply to the cells 23. The simulation may be enhanced by providing the seat pan with heat exchanger pads (27), Fig. 4 (not shown), since it is stated that the application of increased heat to the body gives a similar sensation to increased pressure. These pads (27) comprise tubes (31) and heating elements (33), the temperature of liquid flowing through the tubes being controlled by mixing liquid from reservoirs (51), (53), (55), Fig. 6 (not shown).

Abstract: 1,190,672. Semi-conductor devices. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 7 Feb., 1969 [9 Feb., 1968], No. 6476/68. Heading H1K. Many devices in each of which the distance between the opposite boundaries of a depletion layer where it emerges at the surface of the body is considerably greater than the corresponding distance within the body are produced from a single semi-conductor wafer. The body shown is one severed from an N-type wafer 7 into which a plurality of separate P-type regions 8 had been diffused, these being subsequently linked by a shallower second diffusion of acceptor material. The thickness of the deep part of the P-type region is made to be larger than the extent of the depletion layer at the point of avalanche breakdown, whereas the thickness of the shallow part of the region is made to be smaller than the extent to which the depletion region would otherwise extend; this results in the boundary of the depletion region being of the shape shown by dashed line 11 (rather than being of the shape shown by line 10 if the shallow region were of sufficient thickness). In other embodiments each body may contain one or more (plane) further junctions produced before or after division of the wafer, and each body may be produced with tapered sides (the top being narrower than the bottom) by the use of a knife-edged blade to divide the wafer.
