Title: DC power switch with two fixed contacts and bridging element - has power driven bridge acting as slider
Inventor: KATZMAREK EGON
IPC: H01H33/59
Filed: 1973-10-30
Abstract: An electrical power switch has two fixed contact pieces and a movable bridging element, which results in a shorting of the arcing time, a suppression of the arc and an increased breaking speed. The peak power is also reduced when the switch is opened simultaneously with a lengthened operating time. One of the contact elements is used as a sliding contact with the moving contact acting as the slider. It is power driven and can be accelerated during a relatively long period of time. When in the open position, the slider will no longer be in contact with the fixed element, which will be indicated by a signal. The signal comes into operation before the break and operates the commutator system.

Patent DE-2411627-A1 (DE)
Title: Electrical compensation of mechanical quantity - uses method of superposition of several harmonics of fundamental wave
IPC: G01B7/28
Filed: 1974-03-11
Abstract: The electrical quantity is amplified, and consists of superposition of several electric signals, being the harmonics of a fundamental wave. The fundamental wave necessary for compensation, corresponding mechanically to a circle, consists of two voltages, sin alpha and cos alpha generated by a sine-cosine test value generator. Compensation voltages for higher harmonics are produced from the fundamental wave electronic multiplication and addition. Instead of the analogue sine-cosine generator an incremental pulse generator for forward and backward counting is used. Compensation voltages for the fundamental wave and its harmonics are derived from the pulse train as above. A mechanical quantity received or scanned over a certain length is after conversion into an electrical quantity stored in an analogue or digital store, and then cyclically read out, and its fundamental wave and its harmonics are compensated, using electronic multipliers and adders.

Patent DE-2424597-A1 (DE)
Title: Automatically registering sphygmometer of improved sensitivity - to reduce uncertainties and inaccuracies in detection of diastole
Inventor: SPEIDEL BLASIUS
IPC: A61B7/04
Filed: 1974-05-21
Abstract: The equipment registers blood pressure by stopping two manometer needles in turn. Systolic pressure (at the appearance of sound in the microphone) is registered satisfactorily, but the original equipment has proved to be sometimes indecisive and sometimes premature in detecting diastole (when the sound disappears) and to register diastolic pressure wrongly in consequence. The modification now made consists in providing an additional amplifier (9) and coupling it to the original circuit by shining a light bulb (7) on a photo diode (10). The modified equipment is more sensitive and so more reliably detects the last of the sequence of sounds. The light bulb (7) is exposed to view on the meter, so as to give visual indication of any irregularity in the patient's pulse.

Title: High voltage capacitor - has insulating backing foils interleaved between partly overlapping conducting foils which form winding
Inventor: LAGEMAN HUBERT DR
IPC: H01G4/32
Filed: 1974-12-05
Abstract: A high voltage capacitor consisting of a number of partly overlapping conducting foils to form a winding, with insulating foils interleaved between the turns. Each conducting foil (31, 32, 33) is stuck onto an insulating backing foil (3) to form a long strip. Two such strips are used to manufacture the high voltage capacitor, with another insulating foil interleaved between the two. This design produces a larger capacity for a given high voltage rating. The improvement is brought about by the fact that the strips with the conducting foils are allowed to overlap in the direction of winding. This will eliminate the formation of individual capacitances in series.

Title: Pressure gasification gases scrubbing - by high boiling tar oil combined with alkaline earth dust injection for hydrogen sulphide removal
Inventor: HOELTER HEINZ
IPC: C10B53/00
Filed: 1975-03-07
Abstract: Gases produced during the gasification of coal under pressure are purified by using a hard coal tar oil with a high boiling curve to scrub the tar-containing and dusty components. This system can be expanded and combined with an H2S absorption by introducing in the scrubbing circuit a venturi section where fine alkali earth dust is injected, and a heat exchanger. This recovers heat for any desired purposes and cools the gas so that it lies within the range of the boiling curve of the tar oil. The oil prevents incrustation in the heat exchanger. The gas product is free from hydrogen sulphide.

Patent DE-2519855-A1 (DE)
Title: Electronic voltage regulator for electric motors - comparator generates square wave with frequency and mark space varied to adjust average value
Inventor: KUPFER HANS-JUERGEN
IPC: H02M3/10
Filed: 1975-05-03
Abstract: An electronic voltage regulator for electric motor drives uses digital switching output stage to minimise power boss. The constant voltage source delivers an output dependent upon the reference voltage setting. A comparator stage compares the reference with the actual voltage supplied to the motor and the difference signal controls the power stage. The comparator output is digited, with zero output level if the difference is positive and a one output level of the difference is negative. The power stage output is therefore in the form of a square wave. The regulation is achieved by generating an average of the signal that is varied by frequency and mark/space ratio changes. To protect the output stage against overload a cut-out stage (14) is provided.

Title: Gear change linkage for tipping cab - with conical sprung self locating coupling and sprung catches for vibration protection
Inventor: MAYENBURG MICHAEL VON
IPC: B62D33/073
Filed: 1975-06-20
Abstract: The tipping cab of a vehicle is fitted with a gear selector lever (1) pivoted in the floor using a universal joint. It is coupled to the gear selector linkage under the floor by a detachable catch. Both the lever and the linkage are held in a centralised setting by springs when the connection is opened. This enables the coupling to be re-connected accurately when the cab is dropped, without requiring complex telescopic links. The coupling has conical self locating surfaces which engage slots in the gear linkage, with the slots fitted with springs which secure the coupling. The coupling is thus protected against vibration, especially in heavy vehicles.
