Title: Activated sludge tank for fluctuating influx - automatically lowers weir sill and stops revolving bridge/aerators
Inventor: SCHREIBER BERTHOLD DIPL ING
IPC: B01D21/00
Filed: 1973-05-23
Abstract: An activated sludge tank in a biological sewage treatment has near the efflux an adjustable weir sill.

Title: Gas-fired cupola furnace - using rows of water-cooled tubes across bottom of shaft for uniform melting conditions
Inventor: TSCHERNYJ ANATOLIJ A
IPC: F27B1/24
Filed: 1974-05-22
Abstract: The cupola consists of a shaft mounted above a hearth used for additional heating of the molten metal, the shaft and the hearth being sepd. by transverse, water-cooled tubes covered with a refractory and located at a sufficient distance from the side walls so that the hot gases can travel upwards and the molten metal can flow downwards. The novelty is that the water-cooled tubes are arranged as pairs, forming a "bridge", and at least two rows of bridges are used, the upper row being staggered so it covers the bridges in the lower row and rings of refractory matl. are used as the coating for the tubes. The amt. of stagger used in one row of bridges w.r.t. the underlying row is pref. 0.3-1.5 times the vertical distance between the rows. The arrangement gives even distribution of the hot gases across the entire cross section of the cupola and longer life of the bridges; more efficient operation of the cupola is achieved.
