Abstract: A foamed elastomer is presented, manufactured from a foam precursor composition comprising at least one elastomer resin, preferably an ethylene-propylene-diene resin, at least one thermoset resin, preferably a melamine-formaldehyde resin, a curing agent, and a blowing agent. The elastomer composition optionally further includes cure activators, polymerization accelerators, and a filler material. An important feature of the present invention is that the foamed elastomer has a low density and a high modulus, making it particularly suitable as a shock absorber for a bicycle suspension apparatus.

Abstract: In an electroluminescent lamp having a phosphor layer disposed between corresponding lamp electrodes adapted to apply an excitation potential to cause the phosphor layer to emit light, a front lamp electrode which, in addition to being light transmissive to radiation from the phosphor layer, consists of a thin layer of light-transmissive binder containing a distribution of discrete particles that are characteristically light-reflective and electrically conductive. The electrode particles provide aggregate diffuse outward reflectance sufficient to serve as a reflector behind an LCD display for ambient light that falls upon the LCD display to illuminate the display under light ambient conditions.

Abstract: The invention provides electroluminescent lamps that contain light-emitting phosphors and covering layers which have unusual durability, light transmissivity and resistance to moisture using simple screen printing and doctor blade coating techniques. It is discovered that a liquid dispersion of thermoplastic polymer powder particles, e.g. predominantly of polyvinylidene fluoride, simultaneously: (a) can suspend electrical property additives, such as crystalline, hard, dense particles of generally spherical shape, uniformly in desired concentrations (b) while containing a useful concentration of any of a wide range of such particles, can be deposited by high shear transfer to a substrate in accurately controllable thickness and contour; (c) when so deposited can be fused into a continuous uniform film which has low absorptivity, e.g.

Abstract: An improved fiber reinforced material for use in the manufacture of gaskets is produced by impregnating a nonwoven fabric with an aqueous dispersion of a rubber and filler. The water is then evaporated out of the impregnated fabric. The final product is formed by curing the rubber under heat and pressure.
