Patent DE-2639760-A1 (DE)
Title: Rotary piston hydraulic pump or motor - has two pistons with interlocking helically spiralled faces
Inventor: NEHRING ANDREAS
IPC: F01C3/06
Filed: 1976-09-03
Abstract: The machine has two pistons (1, 2) each of which is a section of a sphere. Each has a helical thread (4, 6) on its internal face. The thread on one piston has one more turn than the thread on the other piston. The two pistons are fitted together with their axes (9, 10) at an angle to each other and with the threads mating together. This leaves gans (20, 20') between the end teeth of the threads and these gaps form variable volume working chambers as the pistons revolve. This construction provides high power for small working masses with high volumetric efficiency. This pistons can be made of materials of different hardness to facilitate slip between their mating parts.

Title: Removal of sulphur di:oxide from flue gases - by water scrubbing with neutralisation using alkaline fly ash
Inventor: JUNKERS GERD DIPL ING
IPC: B01D53/50
Filed: 1976-09-21
Abstract: Furnace flue gases are water-scrubber removing dust and sulphur oxides, and the wash liquid is neutralised and pptd using the alkaline fly ash removed from the gases. Process is for the cleaning of stack gases from furnace and boilers where coal, in particular brown coal, is the furnace fuel. The cost of a scrubbing and neutralisation unit is less, in both capital and operation, than for an electrofilter. The use of fly ash lenssens the cost of neutralisation.

Title: Dispensing pump head for aerosol containers - has cylindrical sleeve with flange as non return valve for cheap manufacture
IPC: B65D47/34
Filed: 1977-03-18
Abstract: The head for an aerosol container pump has a casing (10) with a cylindrical bore reducing in diameter in three steps (11 12 13). An outer piston (22) sliding in the top bore has a projection (23) with a discharge channel (27) in it. The entry (30) to the discharge channel forms a valve seat for the upper end (33) of an inner piston (31).

Title: Adjustable brake pressure system for agricultural trailer - has master cylinder push rod formed with pivoted lever to selectively limit travel
Inventor: MUNCKE LUDWIG
IPC: B60T8/18
Filed: 1977-04-28
Abstract: The tractor and trailer brake system consists of a master cylinder (1) actuated by a foot pedal.

Title: Fibres drafting system - having work roll and arcuate block, both with card clothing, coacting to blend and draft
Inventor: LIVINGSTON EMMETT SHERWOOD
IPC: D01G15/02
Filed: 1978-01-27
Abstract: Fibres drafting system for staple slivers includes a work roll about 35/16" dia. carrying card clothing with about 400 teeth per sq. inch. and coacting with an arcuate under-roll block carrying similar card clothing. The roll teeth are forwardly raked, oppositely to those of the block, and sliver infeed and outfeed roll pairs are of less dia. than the work roll, which runs faster than the infeed rolls and slower than the outfeed rolls. System efficiently parallels short fibres, present esp. in cotton slivers, and thereby eliminates conventional combers from textile mills.
Patent DE-2809121-A1 (DE)
Title: Connector penetrating insulation board - uses cylindrical split insert acting as locking spring in board bore
Inventor: MATHY LUDWIG
IPC: H01R4/36
Filed: 1978-03-03
Abstract: A secured bolted electrical connection is made through an insulation board. The board is drilled to accept a metallic bush (11). The connecting bolt passes through the bore of the bush. The bush is split (13) axially, and the radial face at each end of the split is deformed to give a projecting barb (14, 17). The dimension over the barbs (h) is about 0.5mm greater than the panel thickness. When the bolt tightens a connector against the bush the barbs dig into the metal to give good contact. Simultaneously, the split bush acts like a spring washer to prevent any loosening of the bolt.

Title: Circuit measuring telephone line capacitance - periodically switches line between voltage source and detection circuit receiving discharge voltage
Inventor: KAISER WOLFGANG
IPC: G01R31/02
Filed: 1978-07-25
Abstract: The capacitance-measuring circuit determines whether a telephone line or similar is functional by periodically switching between a constant voltage source and a discharge circuit at a constant frequency. The voltage appearing in the discharge circuit is passed via a filter to an evaluator that determines line capacitance. The point in time at which measurement occurs is chosen so that it is synchronized with the change-over frequency and is also determined by the edge of the voltage profile resulting when switching back to the voltage source. Measurements are almost independent of ripple.

Title: Solar cell combination covered with glass-fibre-fabric-binder plies - whose fibre:binder ratio is closely controlled to ensure same heat expansion as cell material
Inventor: WEINERT MANFRED DR
IPC: H01L31/048
Filed: 1978-08-05
Abstract: Coated solar cell assembly is covered by layers that have about the same coefft. of thermal expansion as the assembly itself. The covering layers pref. comprise a glass-fibre-reinforced binder with the glass-fibre ply made of criss-crossing glass-fibres. The ratio of glass-fibres: binder is pref. calculated to ensure that the heat-expansion coefft. is equal to that of the cell assembly. The covering layer is pref. itself covered by a UV-absorbent PVF film. Solar cell assembly may be based on conventional Si-material but close control of glass-fibre: binder ratio of covering layers minimises risk of delamination caused in prior articles, by thermal stresses.
