Patent DE-2414726-A1 (DE)
Title: Combustion reactor for IC engine exhaust components - has cylindrical chamber with tangential inlet and offset outlet
Inventor: WILL PETER DIPL ING
IPC: F01N3/26
Filed: 1974-03-27
Abstract: Reactor burns unburnt components in exhaust gases of an internal combustion engine, and has a jacketed, heat-insulated chamber into which inlet connection(s) open tangentially extending through the jacket and connected to the outlet channel of the engine, for throughflow of exhaust gases plug secondary air. The chamber also has an outlet connection, and is cylindrical. The inlet connection conventionally opens tangentially into the chamber; the outlet connection is offset in the flow direction w.r.t. the inlet connection, and is conducted tangentially from the reactor chamber. Space is saved, the gases have a long residence time in the chamber, flow resistance is low, and there is good mixing of the gases with the secondary air.

Title: Low loss logic cct. - has series cct. containing collector resistor transistor collector-emitter path and emitter resistor
Inventor: WILHELM WILHELM DR ING
IPC: H03K19/013
Filed: 1974-04-23
Abstract: The series circuit is inserted between the terminals of a supply voltage source. The transistor is a switching type controlled by a first logic input signal, and its collector is connected to an emitter follower output stage. Its emitter is connected to SC components controlled by further input signals. The switching transistor emitter resistor consists of the collector-emitter path of a saturable transistor whose base is connected to an approx. constant bias voltage. A diode is in parallel with the collector resistor, whose forward direction corresponds to that of the conducting transistor. Further input signals are applied through Schottky diodes to the junction point between the emitter of the first switching transistor and the collector of the saturable transistor.
Patent DE-2420011-A1 (DE)
Title: Passive metal electrode for electrochemical cells - made with porous titanium/titanium oxide base coated with fused titanium and noble metal
Inventor: BRANDMAIR FRANZ DIPL CHEM DR R
IPC: C25B11/04
Filed: 1974-04-25
Abstract: An electrode is manufactured by fusing a mixt. of Ti and TiO powders to give a base matl. of TiOx where x is between 0.25 and 1.5. This fused mixt. is porous and so fairly light and is coated with a layer of titanium powder fused again to give good adherence, then finally coated over at least 5% of its surface with a noble metal, e.g. platinum. The pores of the base matl. act as gas evacuation passages. To keep the bottom of the electrode free of gas bubbles, inclined channels are formed which allow the gas flow to the surface of the cell. The electrode can be used in e.g. mercury or diaphragm cells for prodn. of chlorine; for the oxidn. or org. prods. and for cathodic protection. The electrode is not consumed during the electrolysis but offers little electrical resistance. Helps prevent build up of gas bubbles on the surface which affect efficiency and the rough surface allows greater current density to be used.

Title: Supply cct. for incandescent lamps in battery-driven vehicle - has astable multivibrator reducing supply to power low-rated lamps
Inventor: RATZEL RUEDIGER
IPC: H02M3/156
Filed: 1974-06-29
Abstract: The supply circuit for incandescent lamps in a battery-driven vehicles has the lamp (13) supplied from an astable multivibrator (10) whose duty cycle is determined by the lamp rated voltage and the supply voltage, the latter being generally greater than the lamp rated voltage. The multivibrator consists of two complementary transistors (20, 21), whose one collector is coupled over a capacitor (27) to the other transistor base. A protection circuit (14) is connected across the lamp and blocks the astable multivibrator transistors in case of a short circuit. Using a multivibrator as voltage divider avoids providing the battery with a tapping.

Title: Compensating system for press tension rods - compensates thermal and other deformations by direct hydraulic pressure
Inventor: LANGER MANFRED
IPC: B29C45/17
Filed: 1974-07-01
Abstract: The compensating system is used for compensating dimensional changes cuased by applied loads and thermal effects in tension rods.

Title: Free wheel drive roller cage mfr - using pressing and internal pressure to increase bearing dia.
IPC: B21D53/10
Filed: 1974-11-15
Abstract: The standard free wheel roller cage is manufactured by a pressing operation and normally has an axially central roller location band (2) with a larger diameter internal bearing seating (4) at the open-end and a smaller diameter seating (3) at the other, internally flanged, end.

Title: Mechanical handling system with air heated suction grips - minimises condensate in suction units by passing heated compressed air during stand-by phase
IPC: B65G47/91
