Title: Activated sludge treatment of waste water - using recirculating tank with aeration point and sensors for max. and min. oxygen levels to regulate degree of aeration
Inventor: SCHREIBER AUGUST DR ING
IPC: C02F3/00
Filed: 1979-03-14
Abstract: O2 is introduced into an activated sludge process for treating waste water by using a recirculating aeration tank. The sludge-water mixt. is circulated round at a velocity of 20-30 cm/sec. In one sector of the tank there is an aeration point, where purification due to nitrate formation occurs. The O2 content of the mixt. is monitored straight after the aeration zone by means of a first probe which serves to keep O2 content at that point above a certain min. Second probe is mounted on the opposite side of the tank to the first and serves to limit O2 content to a max. value. Used for long term treatment of waste water. Allows a denitrification plus purificn. process to be carried out by allowing nitrate build up followed by breakdown in the tank. This avoids high nitrate levels passing over to the settling system where they would cause accelerated sludge growth.

Title: Closed cycle heat engine - has heat exchange between isothermal compression and expansion to allow use of low temp. energy source
Inventor: COENEN LOTHAR
IPC: F01K25/10
Filed: 1979-03-30
Abstract: In the system air drives a turbine, or engine. The turbine is surrounded by a heating jacket so that the air expands isothermally. The expanded air passes to a compressor which is surrounded by a cooling jacket and by which it is compressed and cooled to below atmospheric temperature. The compressed cold air passes to a heat exchanger in which it is heated at constant volume by indirect heat exchange with the atmosphere. This also raises its pressure, and it then passes to the turbine to repeat the cycle. The turbine drives the compressor and an external load. The heat extracted from the compressor is added to the turbine.

Title: Cell smear microscopic evaluation - by filtration of cells from suspension using a porous plastic membrane which is rendered transparent and applied to a microscope slide
Inventor: ASEIKENS BERNHARD DR MED
IPC: G01N33/483
Filed: 1980-06-25
Abstract: New process is claimed for recovery of cell prepns from liq. media for subsequent evaluation, in which the cells are applied to a transparent microscope slide, fixed, stained, and examined and evaluated in the laboratory. Starting from solid cell prepns. the cells are suspended in a suitable liq. medium and the suspension is filtered by means of a porous plastic membrane filter having a pore size such as to retain the cells under prepn. The cells are fixed while on the membrane filter, simultaneously with or subsequent to the filtration. Before or after laying on the microscope slide, the membrane filter is chemically converted into a transparent state, and the cells are stained using one or more staining baths before or after application to the microscope slide but after the chemical treatment to render the membrane filter transparent. The new process allows the procedure of parent patent DE2928790 to be extended to cells not originating from a homogeneous liq. medium, e.g. cells from a smear test.

Title: Fuel injected IC engine - passes liq. fuel via heated capillary nozzle to give explosive evaporation producing complete mixing with compressed air
Inventor: BAENTSCH ERICH
IPC: F02B1/02
Filed: 1980-07-18
Abstract: The i.c. engine injects pressurised liquid fuel via a nozzle with capillary gap which is heated by the combustion in the cylinder. Explosive evaporation occurs on injection to produce an intimate mixture with the air compressed in the cylinder rather than this air being displaced by the fuel as it enters. The size of the miature volume so produced in the cylinder depends on the engine load-dependent amount of fuel injected. It also depends on the pressure and temp. differences between the air in the cylinder and the fuel in the gap, which should be kept at a pressure to ensure it remains liquids at that point.
