The invention relates to a heat-accumulating and heat- equalizing stone, plate, element or equalizing mass, which are intended for building construction and which consist of a binder, a base material and possibly other additives. The accumulation and equalization of heat are combined here with mechanical strength, because a substantial part of the base material consists of steatite and/or a magnes...

A cooling unit for automobile air conditioners includes a pair of scroll-shaped blower cases each composed of an upper case member integrally formed with the upper case member of a cooling case, a lower neck portion integrally formed with the lower case member of the cooling case, and a removable lower case portion detachably disposed between the upper case member and the lower neck portion. The c...

An apparatus for cooling a hot product gas, the latter is passed through a tubular zone. The product gas contains particles which, on entering the tubular zone, are tacky, but lose their tackiness through cooling in said zone. Within said zone a cooling gas flow forms a gas wall, which prevents contact between the product gas or the tacky particles contained therein, and one of the fixed walls in ...
