Title: Stratified charge carburation for wankel engine - with supply of rich mixture to preliminary chamber independently of induction stroke
Inventor: FRACKE KARL DR
IPC: F02B19/10
Filed: 1974-07-22
Abstract: Stratified charge carburation system for Wankel engine or for in-line engine, as shown in the drawing, comprises a rotary single or twin-vane compressor which draws a rich mixture from the carburettor and passes it via a non-return valve at the end of the induction stroke and during the compression stroke into a preliminary chamber in which the sparking plug is mounted. One compressor is provided per preliminary chamber. In the case of a reciprocating-piston engine, a single-cell compressor is used with a slide and driven at half the speed of the crankshaft, filling the preliminary chamber one during each revolution.

Title: Multiple station grinding machine - controls grinding wheels so all have same surface speed
Inventor: SCHALLER ROBERT L
IPC: B24B5/38
Filed: 1974-11-06
Abstract: Each centreless grinding station has a grinding steel (10) and a regulating wheel (11) with a through feed support for a workpiece (W). The grinding wheel speed is set by a control unit (20) passing an analogue signal to a summing unit (21) which also receives a grinding wheel surface velocity signal from a multiplier (22). The latter receives a signal from a wear sensing mechanism (32) and a signal from a convertor unit (31) which multiplies the wheel size and velocity signals. The wheel speed is increased as the wheel diameter is reduced and the wheels all operate at the same given speed. As the wheels are worn they are moved towards the workpiece to compensate for this wear.

Title: High power transmission cable - has copper or aluminium ring-shaped hollow conductor with cooling agent
Inventor: BIRNBREIER HERMANN DIPL PHYS
IPC: H01B7/30
Filed: 1974-11-23
Abstract: The high power cable has a cross section that is approximately ring shaped with a hollow inner conductor whose coating seals in the cooling agent. The cooling agent flows through the hollow conductor. The cable is designed to transmit direct or alternating current. The skin effect of the hollow conductor is eliminated by designing the internal radius according to a specific formula relating to the external radius of the hollow conductor. The dimensions of the hollow conductor are optimised and are independent of the cooling agent or the cooling requirements. The hollow conductor can be made from copper or aluminium. An empirical formula has been derived to give the relationship between the internal and external radius of the hollow conductor with the dimensions given in mm.

Title: Piston actuated valve with blocking element - has blocking element sealing disc moving freely in perforated guide
IPC: F16K31/122
Filed: 1975-01-14
Abstract: The piston actuated valve, has a blocking element in valve housing which is actuated by a spindle connected to the actuating piston. The hollow piston-shaped blocking element slides in a perforated cylinder in the valve housing and this piston is correctly sealed in closed position regardless of the number of times this piston has travelled past perforations. The circumferential sealing disc which slides past the perforations (6) of the guide cylinder (5) is fitted and clamped on the blocking element (4). This sealing disc contacts by its circumference the guide cylinder (5) bore. The width of the circular groove edge area (25) for the sealing disc is greater than the thickness of the sealing disc (22). The gaps formed between the sealing disc edge and the groove allow free movement of the sealing disc edge.

Title: Oil change device for heavy lorries - using automatically reversible pump controlled from cab by driver
Inventor: KAPELLAS ANTONIOS
IPC: F01M11/04
Filed: 1975-10-29
Abstract: The engine sump has two connections to an electrically driven pump which has connection to exchangeable oil containers. When the pump is energised in one direction by a switch it sucks oil from the sump through one connection and delivers into one container. A float switch operates a potentiometer which gives visual indication on the dashboard of how much oil has been taken out. When the pump is energised in the other direction by another switch it fills the sump from the other container which holds fresh oil. A float switch in this container gives visual indication on the dashboard of the quantity of oil put in. The system enables drivers to carry out oil changes in regions with few garages.

Title: Table ice hockey game - has toy figures rotated through slipping clutch drive to prevent damage
Inventor: GAUSELMANN PAUL
IPC: A63F7/06
Filed: 1975-12-08
Abstract: The table ice-hockey game has a rectangular playing surface (10) with a goal (11) at each end. The toy figures (12) are mounted on spindles (27) supported in bearing brackets (26).

Title: Safety valve preventing damage by domestic machine leakage - is actuated by monitor responding to presence of water
Inventor: KLEIN HARTMUT
IPC: D06F39/08
Filed: 1976-02-19
Abstract: A safety valve for protection against the failure of a hose or a pipe, esp. against damage by water, is installed in a line to a point of consumption, and is partic. applicable to domestic machines connected permanently to the water supply. In the event of any undesired release of the medium in the line, a monitor initiates an electrical, mechanical, pneumatic or hydraulic sequence which energises or releases the spindle of the supply valve, so that the valve returns to its seat and the supply is cut off. This rules out the possibly of serious damage following uncontrolled leakage of the hose to a washing or other machine. The system can be applied by modifying the monitor to the protection of lines carrying other media than water.

Title: Rotary piston IC engine with 2 annular working chambers - has wave form surfaces face to face with two mounted on rotating flange
Inventor: NEHER HANS HELMUTH
IPC: F01C9/00
Filed: 1976-03-29
Abstract: The rotary piston IC engine has 2 annular working chambers formed between the regular wave form inner end faces (21', 22') of 2 co-axial hollow cylinders (21, 22) and matching surfaces (27', 27") of a flange (27) on a rotor (24) fitting closely inside the cylinders.
