Patent DE-2358915-A1 (DE)
Title: Digital signals transmission system - suppresses interference signals between impulse or breaking up impulses even when rapidly appearing
Inventor: RIEWE FRANZ-JUERGEN
IPC: H03K3/013
Filed: 1973-11-27
Abstract: Front flank of an incoming pulse releases a gating pulse delayed by a specified time with respect to the flank. The gating pulse width, together with the above delay time, is shorter than the useful pulse width. A gate between signal input and output is open only when the gating pulse is present. The delay time is about 50% and the gating pulse width about 25% of the useful pulse width. When two parallel channels are used, with a coupling circuit at their outputs, one channel consists of a differentiating element and a digital delay line generating the gating pulse. Outputs of the two channels are connected to the inputs of a coincidence circuit delivering the output signal. The digital delay line consists of an oscillator followed by a frequency divider.

Title: Catalyst prodn - in an evacuated chamber, with deposition by ion bombardment of the substrate
Inventor: CAIRNS JAMES ANTHONY
IPC: B01J37/34
Filed: 1973-11-29
Abstract: In a process for the production of a catalyst, a material is dispersed onto a substrate in a layer of practically atomic thickness. The dispersed material may be a catalyst or may be a component of a catalytic system. Where several components are distributed onto the substrate the substrate is later treated in such a way as to cause the components to react and form the catalyst. The catalyst is applied to the substrate by ion bombardment in a vacuum. Production of catalysts for general applications excluding electro-catalysis. Only small quantities of catalytic material are required.

Title: Two stage combustion by suspended compressor - has piston and non-return valve for each combustion chamber of engine
Inventor: FRACKE KARL DR
IPC: F02B47/00
Filed: 1974-03-12
Abstract: Two stage combustion by suspended compressor is reciprocating and rotary piston engines, where a compressor has a piston and a non-return valve for each combustion chamber of the engine, and is driven by the crankshaft via toothed elements. It produces the combustion of the second stage, in which it presses its hot compressed air through the non-return valve directly into the combustion chamber, when the combustion of the rich mixture terminates so that the combustion of the accumulated monoxide and hydro-carbons results with the excess air as the second stage. Several bores pass into the combustion chamber, to which the compressor is connected. Consequently there is maximum turbulence through the entering compressed air so tht combustion in the second stage is accelerated and improved.

Title: Temperature-sensitive item fireproof safe - has core enclosed by thermal insulating material
Inventor: GILBERT ALWIN ING GRAD
IPC: E05G1/024
Filed: 1974-03-21
Abstract: The safe is for the storage of items such as magnetic tapes, films etc. and comprises a core (3) accommodating the items, enclosed in a high-efficiency temperature resistant thermal insulating material (2).

Title: Torsional vibration damper - has rotary and sliding components with machined faces spring loaded together
Inventor: ZELLINGER HERMANN ING GRAD
IPC: F16F7/00
Filed: 1974-11-08
