Title: High strength aggregate - obtd. by pelletising and baking clay-silicate raw materials, used for road-making, normal concrete, or lightweight concrete
Inventor: NEUMANN-VENEVERE PETER PROF DR
IPC: E01C7/14
Filed: 1979-03-21
Abstract: Clay-silicate raw materials are highly compacted to make pellets or briquettes which are subjected to a brief baking process is which the pellets are exposed to mechanical stresses due to thermal shock. The raw materials pref. consist of clay or loam used to make dense or porous aggregates. The clay etc. is pref. compacted in a press using ca. 7 t/m2, so the pellets have a high green strength and do not crumble during rapid baking in furances with a short length. Baking pref. results in either a sintered aggregate, or grains with a molten skin on their surface; in either case, baking produces material with a desired bulk density, abrasion resistance and water-absorption.

Title: Removing carbon di:oxide from protective furnace atmos. - derived from part of fume gases
Inventor: MINKLER WERNER ING GRAD
IPC: F27B9/04
Filed: 1979-07-27
Abstract: In a continuous metal-treating furnace with a protective atmos. formed by partial combustion of gas, wherein a heating chamber for the moving stock is followed by a cooling chamber, the protective furnace atmos. is formed by reducing the CO2 content of a recycled portion of fume gas. This portion is washed in a tower by cleansing fluid which then passes through a circuit for expelling the absorbed CO2. This circuit includes a heat exchanger which is located in the cooling chamber and hence utilises the heat from the travelling stock which would otherwise be wasted. Many metallurgical heat treatments require a low CO2 content in the furnace atmos., e.g. to prevent take-up of carbon. This generally involves separate units and extra energy consumption, which the present plant obviates.
