Title: Press for dewatering stacked asbestos cement plates - has sandwiched water draining grooved plate with perforated cover and fabric
Inventor: EXNER GUENTER
IPC: B30B9/10
Filed: 1977-04-27
Abstract: The press is used for dewatering of plates made from fibrous materials. Fibres are bonded by hydraulic bonding agents. The press is used especially for asbestos cement plates which are stacked with sandwiched intermediate layers. Pressing operation is rapid and plates can be separated soon after pressing. The intermediate layers (1) have dewatering channels (4) on their top surfaces. These channels of plate are covered with a perforated plate (6).

Title: Two=stage turbocharger for IC engine - has turbines in parallel and compressors in series for independent operation
Inventor: FUHRMANN ERNST PROF DR
IPC: F02B37/18
Filed: 1978-04-27
Abstract: The engine (1) has an air inlet (2) and an exhaust gas outlet (3). Branches (17, 18) from the exhaust lead to two turbines (11, 8). The exhaust flows through these in parallel and the flow is controlled by valves (19, 20) in the exhaust pipe (3). Each turbine drives a compressor (5, 10) which delivers air to the engine inlet. The air flows through the two compressors in series. The second stage compressor (10) is smaller than the first stage compressor and its driving turbine (11) is smaller than the other turbine (8). Each turbine and therefore each stage of the compressor can thus be controlled independently.

Title: Swirl control for intake of radial blower - obtained by use of different rings of fixed intake vanes
Inventor: WIESER RUDOLF DIPL ING DR
IPC: F04D27/02
Filed: 1978-07-01
Abstract: A radial blower, driven by a constant-speed asynchronous motor, is intended esp. as main blower in the prim. circuit of a helium-cooled, high-temp. nuclear reactor.

Title: Sport shin-bone guard of polyurethane foam - is roughly semicircular shell moulded with closed surface bonded to core
Inventor: BRUECKNER GEORG F
IPC: A63B71/12
Filed: 1978-11-03
Abstract: A half shell moulded in one piece from soft, integral polyurethane foam, forms a shinbone guards for sportsmen. The contour of the guard suits that of the lower leg, and the thin-walled shell is attached by burr-fabric fastenings. The cross-section of the moulding is approx. semicircular with a radius at the upper end which is slightly larger than that at the lower end. It reaches from the ankle to the knee and has internal grooves for draining any perspiration. The guard has optimal absorptive capacity for blows and impacts and whilst being capable of withstanding rough treatment over a long period without sustaining any damage it can be produced easily and cheaply. The mode of manufacture of the foam with a practically closed surface skin blending into the cellular core results in a high degree of elasticity.

Title: Medical measuring cell attachable to syringe - measures electrical conductivity of blood by electrode in sampling chamber connected to resistance bridge
Inventor: ROEDEL EGON DIPL CHEM
IPC: G01N33/49
Filed: 1978-11-22
Abstract: The cell measures the electrical conductivity of blood and can be inserted in a syringe. The cell consists of transparent glass or plastics and has a central sample chamber whose walls are smooth and cannot be wetted by blood. The chamber diameter is kept between 2 and 3 millimetres to minimise the sample quantity while permitting stable, reproducible measurements. Two gold electrodes are inserted in the chamber and the electrical conductivity of the blood between them is measured by an a.c. resistance bridge. The cell is inserted on to a syringe by a cup and cone fitting and the blood is put under pressure by moving the plunger. The blood conductivity is then used to determine the cell volume density of blood.

Title: Regulator to control liquid level - has resistive probe coupled to regulator to allow tank discharge to be controlled
Inventor: GEISLER RUDOLF
IPC: G05D9/12
Filed: 1979-03-01
Abstract: A liquid level controller to maintain a constant flow discharge from a tank is designed to provide high accuracy and to be unresponsive to transients caused by surface wave action. A resistive probe (1a) mounted on an insulated bracket (3) provides an accurate value for the height of the liquid (N) in the tank. The regulator circuit (4) operates on a sampling time base selected to ensure that any short duration transients are ignored. Liquid level is maintained at the required value by the regulator output being used to control the setting of a valve (6) located in the discharge line (7). When operating in this mode the pumped supply operates at a preset value. An alternative mode uses the regulator signal to control the pump.
