Abstract: Modified or filled rebond polyurethane foam structures having desired plushness and compression without adversely affected tensile strength at a given density as compared to unfilled rebond polyurethane foams are formed from an admixture of shredded or chopped polyurethane foam particles and a finely divided inorganic mineral filler, such as barium sulfate or calcium carbonate or mixtures of these and like mineral fillers, that is further mixed with a substantially non-foam forming liquid prepolymer binder that is free of surfactants in foam-stabilizing amounts. A portion of the polyurethane foam particles, from about 10 to about 60 parts by weight based upon 100 parts by weight, is replaced with filler. For each 100 parts by weight of the combined foam particles and filler, about 10 to about 30 parts by weight of prepolymer is added. After the wetted admixture is compressed to the required density, the prepolymer binder is cured with heat and/or steam.

Abstract: A wafer for use in the selective connecting and disconnecting of plastic tubes incorporates a fuse in an aperture. The fuse is made of a three layer laminate having light transmission characteristics which change after the wafer and its laminate have been heated. The three layers comprise two outer transparent layers and an intermediate layer having limited light transmission characteristics. When the wafer is heated the intermediate layer shrinks thereby changing the light transmission characteristics by providing a path for light to pass through the laminate without passing through the intermediate layer.

Abstract: Rubber mixtures prepared from at least one styrene/butadiene rubber gel and at least one rubber which contains double bonds and optionally further fillers and rubber auxiliary substances are in particular suitable for the preparation of vulcanizates having unusually high damping at temperatures of from -20 to +20.degree. C. as well as unusually low damping at temperatures of from 40 to 80.degree. C. The rubber mixtures may therefore be used, for example, to manufacture vehicle tires which grip in the wet and have low rolling resistance.
