  • Heat absorber
    Patent number: 4432413
    Abstract: In ambient-air heat absorbers composed of many heat exchanger elements arranged one above another, the flowing air often flows too smoothly through the intermediate spaces, so that the heat exchange takes place only incompletely. As a result of the insertion of lattice grids onto the (smooth) surface of the heat exchanger elements, this uniform flow is varied. The result of this is a greater absorption of heat by the absorber.

  • Plaster mixture consisting of an aqueous polymer dispersion containing pigment and filler
    Patent number: 4010134
    Abstract: The sound absorbing properties of plasters, based on synthetic resin emulsions as binders, are improved, if as binder dispersions are used the polymer content of which has a dilatometrically determined second order transition temperature of between -20.degree. C and +10.degree. C, and if the fillers consist of at least 70% of material having a grain-size of from 0.35 to 1.5 mm.
