Title: Activated sludge purificn. plant for domestic effluent - is compact packaged unit with sludge recycling and capacity for excess sludge
Inventor: DAUNAY JACQUES
IPC: C02F3/12
Filed: 1976-12-31
Abstract: Waste water is purified first by contact with aerated, activated sludge and then by removing sludge by decanting. The plant comprises a vertical, cylindrical decanting chamber with convergent, conical base. The decanting chamber is located coaxially within a vertical, cylindrical tank to leave an annular space between inner chamber and outer tank; activated sludge treatment takes place in this annular space. The annular space is now divided into two compartments by a vertical, diametral, partition. One compartment is devoted to aeration treatment and the second is internally baffled to serve as an excess sludge silo as well as a supplementary decanting space. The second compartment baffles pref. include lamellar flow chicanes for horizontal currents over the full length of the compartment. Used as an activated sludge plant for biological purificn of domestic waste water, partic. for the treatment of effluent from an individual house. Provides an compact, inexpensive design with efficient sludge recycling and capacity for excess sludge awaiting periodic evacuation. There is no danger of incoming waste water contaminating treated effluent.

Title: Computer processing of ground formation diagraphic data - uses statistical model to supply corrections for data from sensors
Inventor: SUAU JEAN
IPC: G01V11/00
Filed: 1977-09-21
Abstract: Probes traverse the ground formations in bore holes in the search for fossilised fuel or minerals. The characteristics of the formations are studied by combining data with that from a statistical model to replace missing data. A probe assembly (12) contains probes and sensors to measure porosity (18a) and density (20) as well as an acoustic sensor (16) to determine acoustic transit time. The sensor outputs are applied to amplifiers (42,36,24,26) and calculators (28,38) to determine the density and porosity. These values with the transit time data (delta-t) are applied via analogue-digital converters (46,48,50) to a transmission unit (52). The received (56) information is correlated (58) for probe depth and processed to effect zero shifts and to group the data. A CPU (64) provides a statistical model for use in applying corrections to the data.

Title: Prodn. of carbon black with increased yield - using hot gas stream from combustion of fuel in oxygen-superheated steam mixts. (PT 15.11.78)
Inventor: SUROVIKIN VITALY FEDOROVICH
IPC: C09C1/48
Filed: 1977-12-08
Abstract: Furnace carbon blacks are made by complete combustion of fuel in mixts. of oxygen and superheated steam with vol. ratio 1:1.5-10 and introduction of a hydrocarbon raw material into the hot combustion gas stream, with subsequent cooling and sepn. of the product. Used in reinforcement of rubbers, plastics, etc. Temp of the combustion gas stream is reduced by presence of steam, preventing reaction of the carbon formed with CO2, H2O, etc. and giving better control of the process. Yield of black and its physical-chemical properties are improved. Lower temps. in the combustion chamber eliminate the need for water-cooling of the walls.
