  • Halocarbon and azeotrope refrigerant compositions containing offensive warning component
    Patent number: 4294716
    Abstract: This invention deals with the identification of materials which can be used as an odorant for halocarbons and azetropes, primarily chlorofluorocarbons, commonly used as refrigerants in refrigeration, airconditioning and process cooling systems. Refrigerants containing less than 2% by weight of an inert volatile compound having an offensive odor unobjectionably attracts the attention of the human olfactory senses when a refrigeration system containing such a refrigerant develops a leak. The offensive odor acts as a warning signal and permits the refrigerant leaks to be detected and remedied as they occur, thereby decreasing the quantity of refrigerant that would otherwise be lost, as well as preventing loss of perishables, uncomfortable or unworkable surroundings, damage to sensitive equipment, increased use of electrical energy, and possible incremental damage to the stratosheric ozone layer.

  • Upholstered furniture having improved flame resistance
    Patent number: 4294489
    Abstract: Flame resistance of upholstered furniture is significantly improved by interposing between the cover fabric and the padding or applying to the top side of the cover fabric a layer of neoprene foam capable of forming when exposed to a burning cigarette or under the conditions of a standard flame spread test, a thermally insulating char which does not smolder, and which maintains its structural integrity. The neoprene foam must be so formulated that it also is capable of evolving at combustion temperature sufficient amount of water to efficiently cool the affected area. Normally, the latex from which the foam is prepared is formulated with a char promoter and a hydrated inorganic compound. Upholstered furniture of this invention passes a burning cigarette test and performs extremely well in the flame spread test.
