A frost resistant glycol-free coolant composition or process for cooling apparatus is used for cooling, with such composition, which comprises an aqueous solution of a water soluble alkali metal salt, or a mixture of two alkali metal salts. Particularly suitable alkali metal salts are alkali metal acetate and alkali metal formate. Depending on the nature of the particular alkali metal salt or salts, and the extent of frostproofness that is required, the compositon can further contain urea and/or a glycol antifreeze, such as ethylene glycol. Optionally a corrosion inhibitor can also be used.

Apparatus for the classification or separation of solid materials

The present invention relates to a priming or body paint having active anti-corrosive and surface cleaning effect containing binding material, pigment and optionally solvent, filler and/or additives, characterized in that said pigment, optionally in addition to other known pigments, comprises:

Priming and body paint having an active anti-corrosive and surface

According to the process the grains are led to the surface or ducts of a rotary element farther in than the flange of the rotary element, thus the coarse grains are led to the flange of the rotary element in a counterflow to the sizing medium. In a housing on an impeller deflecting elements are arranged, the carrier medium and the mixture of material to be sized are fed into the housing by medium inlet tubes, and led out by coarse and fine fraction outlet tubes or nozzles, and one inlet disc is arranged above the impeller so that they form an annular assorting space which is divided by deflecting elements into segments, and a passage connected to the inlet tube of the sizing medium is formed between the mantle of the inlet disc and the inner wall of the housing at its upper end, where ducts leading into the assorting space are arranged in the inlet disc farther in than its flange, and which are connected to the carrier medium inlet tube.

Method and apparatus for sizing grains smaller than 300.mu.

An improved process for accelerating the digestion process in the Bayer alumina process is provided which promotes both the goethite-hematite conversion and a more perfect and quick dissolution of the diaspore. The above is achieved by carrying out the digestion in the process of 5-20% by weight calculated on the dry weight of the bauxite of a novel hydrogarnet catalyst.
