Title: IC engine optoelectronic ignition system - has photodetector apertured opaque element and transistorised ignition circuit with several Darlington pairs
Inventor: FORD ERIC HAROLD
IPC: F02P3/04
Filed: 1976-07-24
Abstract: Opto electric ignition system for IC engine for use with an ignition coil includes a photo-detector which will conduct when exposed to radiation; a radiation source; an opaque element having apertures or slots therein positioned between the radiation source and the photo-detector. Means for rotating the opaque element in timed relation to the engine revolutions and a transistorised ignition circuit having a several switching Darlington pairs connected between the photo-detector and the ignition coil, and switching in inverse relation to the one another are provided. The first Darlington pair of the circuit also switches in inverse relation to the photo-detector. On the energisation or de-energisation of the photo-detector, the transistorised ignition circuit causes fast switching of the primary winding of the ignition coil to induce the spark voltage in the secondary winding.

Title: Auto-thermal coal gasification - by plunger pumps compressing fuel portions to high reactor pressure and extracting ash portions
Inventor: LANGHOFF JOSEF DIPL CHEM DR
IPC: C10J3/30
Filed: 1977-01-05
Abstract: In an autothermal process of gasification under pressure for solid fuels, e.g. granular hard coal with a gasifying agent, separate portions of fuel are displaced by a plunger pump and compressed to the active pressure in the reactor. The portions are then injected in a continuous stream into the pressurised space of the reactor. Similar pumps are used to release the pressure of the ash in portions to atmospheric pressure and to discharge it. Process simplifies the feed of fuel and the discharge of ash for a gasifier and creates the preconditions for a pressure rise in the reactor space. Both the fuel throughput and the quality of the production gas can be improved considerably.

Title: Vertical pressure spring element assembly - has spring support of two concentric, axis-parallel rod groups, each coacting with pressure disc and inner rod coupling disc to form cage
Inventor: HUTT HELMUT
IPC: F16F1/32
Filed: 1977-07-05
Abstract: A compression coil spring, or a stack of plate springs (1), is located inside a telescopic housing (15, 16). Circular end plates (2, 3) at each end of the spring pack transmit the axial compression force to the spring elements. An internal cage, formed by cylindrical rods (4, 5) provide radial support for the spring. Sliding plates (6, 7), attached to opposite end plates by alternating rods (4, 5), move axially apart when the spring stack (1) is compressed. A central spacer bar (8), attached to one slider plate (6) acts as spacer between the plates, thus it controls the maximum and minimum axial length of the spring assembly.

Title: Domestic sewage treatment - in two biological stages with self-induced sludge recycling
Inventor: RENNER HELMUT DIPL ING DR
IPC: C02F3/12
Filed: 1977-09-13
Abstract: A domestic sewage treatment plant consists of a pre-clarification tank and two biological stages, each consisting of an aeration section and a reclarification section. The turbulence produced by aeration is utilised to convey activated sludge against the general flow direction from the second stage back to the first stage. This saves the necessity for any recycling pumps and the power consumption for their drive. The reflux taxes place during periods of little main flow. The risk of sludge being washed out by impact loads is greatly reduced.
