Patent DE-2532435-A1 (DE)
Title: Positioner for electronic engine speed regulator - has spring element with steep characteristic at low and flatter characteristics at higher engine load
Inventor: WALLBAUM HELLMUT ING GRAD
IPC: F02M7/08
Filed: 1975-07-19
Abstract: Positioning element (1) is intended for an electronic speed regulator of a combustion engine and has a spiral spring acting on the carburettor or injection pump. The spring (6, 7) has a force versus stoke characteristic which, in the region of low engine load, is steep, whilst in the subsequent higher load regions, it is flatter. The characteristic may be linear, at least in the first, steep region. The injection pump may act on the positioning element in the sauce direction as the spring, which is then so arranged that the maximum force of spring and pump combined acting on the positioner does not exceed the force which a spring with the steep characteristic would exert at that point.

Title: Signalling system between main and PBX telephone exchanges - prevents loss of secondary signalling signal information by repeating it
Inventor: JAEGER HORST
IPC: H04Q1/44
Filed: 1975-07-23
Abstract: The signalling system, for signalling between a main telephone exchange and a PBX ensures that secondary signalling signals are easy to transmit whilst guaranteeing that signals have through-access in certain directions. 50 Hz ac is used for main signalling and AF multiple-freq. signals for secondary signalling. The secondary signalling signal (denoting type of connection and/or authorisation) that follows the main signalling immediately after a subsequent second main signalling signal which is the same as the first has been transmitted. This ensures that no information is lost if the first secondary signal is distorted.

Title: Combustion of comminuted distillation residues - preventing formation of slag, and allowing heat recovery
Inventor: BRAUN BERND
IPC: F23G5/46
Filed: 1975-07-25
Abstract: Burning distillation residues is carried on by comminuting them, filtering off non-comminutable fractions, then preheating, atomising and burning the comminuted residues, and converting the heat of combustion to utilisable energy. Pref. the residues are kept in continuous motion to prevent lump formation, and the waste gases of combustion are detoxicated. Appts. comprises a pipe leading from the outlet of a distillation plant to a grinding mill, a filter, a preheater, and a burner with a nozzle and connected heat exchanger. In the nozzle is a longitudinally slidable clearing needle. At least one pump delivers the residues from the outlet of the distillation plant to the burner. Upstream of the grinding mill may be a mixing vessel with a motor-driven agitator for the residues.

Title: Snap fastening pivot for windscreen wiper blade - is constructed with pivot end slotted to slide over tag in wiper arm
Inventor: DEUTSCHER HANS-CHRISTIAN
IPC: B60S1/40
Filed: 1976-07-01
Abstract: The wiper blade mounting (10) is secured to the pivot bolt (21) with a lateral mounting to reduce the height of the wiper linkage over the windscreen. The end of the bolt is wider (24) and has a slit (23). This locates over a tag (16, 17) inside the wiper arm so that the bolt can only be pushed through the wiper arm in one angular setting. The blade is then swivelled to its operating setting and a secure fitting is abtained. The slot positioned is such that the wiper blade is set at right angles to the arm. a position which is impossible to achieve under normal wiping. The tag is part of a stamped tag into the top of the blade mounting so that no other fittings are required.

Title: Farm yard manure gas plant - with main and secondary fermentation tanks covered by fixed and floating tarpaulin domes
Inventor: WEBER FRITZ
IPC: C12M1/107
Filed: 1977-03-15
Abstract: A plant for the recovery of farmyard manure gas consists of a main and a secondary fermentation tank, both not heated and covered by a floating layer. Both the main tank which has a fixed gas tarpaulin dome, and the secondary tank which has a floating dome, have a gas extraction hoses leading to a gas filter.

Title: Frames connected edge to edge by fish plate - are held by screws and system includes eccentric for drawing frames together
Inventor: HAU DIETER
IPC: F16B5/02
Filed: 1977-07-20
Abstract: In a frame construction, two frames (3, 4) are connected edge to edge by a fish plate (6) across their adjacent sides. The plate is secured to each of the frames by a respective screw (7) and one of the screws passes through an eccentric (8) which is supported for rotation in a hole (9) in the plate.
