Patent DE-2931770-A1 (DE)
Inventor: HUSER GUIDO
IPC: H01H1/38
Filed: 1979-08-04
Abstract: The plug contact consists of a connecting part (16), a contact part (1) and a plurality of spring-loaded contact elements (13). The contact element (1), which is equipped with an inclined plane over which the projecting end (5) of the spring elements (6) slides, the spring elements producing the necessary force-fit of the plug contact, results in the insertion and removal intrinsically being possible manually, because the insertion force to be absorbed has been very considerably reduced by the measures taken. In addition, the quality of the refined contact surfaces is no longer adversely affected, even as a result of continuous insertion and withdrawal, because the contact surfaces slide on one another without any pressure while the plug contact is being made; the spring-closure force is temporarily bridged and does not become effective again until the insertion force is reached. <IMAGE>

Title: Fluid surface detector and indicator - determine relative position in inaccessible tanks using contact, reference sensors and transfer mechanism to measurement unit
Inventor: BOYSEN MOGENS BREDAHL
IPC: G01F23/00
Filed: 1979-10-09
Abstract: A measuring device is for the surface level of a fluid or other medium from a given point in a tank. A measurement probe is used with a scanner generating a signal when it touches the medium. It gives rapid accurate measurement and can be used for applications where manual access is restricted, e.g. for underground petrol tanks. A calibrated roller forms part of a transport system moving the probe vertically in the tank and coupling it to the recording circuits. Signals passing to the latter have frequency proportional to the vertical probe speed. A reference sensor produces a reference signal when the probe is at a defined upper position. The recording circuits produce a tank contents indication from reference, measurement, and contact signals.

Patent DE-3013061-A1 (DE)
Title: Bi-directional rail vehicle with redundant control units - has direction selection switch to couple alternative unit to controlled device
Inventor: DRESSLER HELMUT DIPL ING
IPC: B60L3/00
Filed: 1980-04-03
Abstract: The control system uses two identical control units either one of which is in use at one time, with the other unit switched into operation if the first unit fails. The selection of either unit is made in dependence on the direction in which the vehicle is to travel, e.g. using a travel direction selection switch (6) between the control units (1,2) and the controlled device (7), determining which of the output signals (4,5) is fed to the latter. Both units (1,2) are tested by alternately activating them for selected operating times using the selection switch (6), so that a failure of the stand-by system can be detected. The coupling between the selection switch (6) and the direction selector (8) can be interrupted when one unit (1,2) is faulty to allow the other to be coupled to the controlled device independent of the direction of travel.

Adjustable bars (e.g. 17) position the mould (30) with its gate opposite the nozzle (31) of the wax injector. Uniform quality of wax models is maintained and high output obtd. It is applicable to all existing wax injection equipment.

Title: Capacitive sensor detector circuit with stable response threshold - has reference capacitor periodically connected to oscillator circuit
Inventor: ULRICH HELMUT DIPL CHEM
IPC: H03K17/955
Filed: 1980-07-08
Abstract: A detector circuit with a capacitive sensing element contains an oscillator whose frequency is affected by the sensor capacitance and an evaluation circuit controlled by a frequency measurement circuit. It maintains a very stable response threshold, and thus is very secure against circuit faults and unahtorised interference. The frequency measurement circuit contains a comparison capacitor periodically connected to the oscillator circuit instead of the capacitive sensor element by a changeover device. A counter controlled by the changeover device counts in one direction whilst the reference capacitor is connected to the oscillator and in the opposite direction whilst the capacitive sensor is connected. A counter status detector controls an evaluation circuit after each connection of the capacitor or sensor according to the contents of the counter.

Title: Connecting clamp for ensuring continuity with cable screen - uses toothed metal section inserted beneath tongued flap, formed at cable end, by screen and sheath
Inventor: LAAR HANS ING GRAD
IPC: H01R4/64
Filed: 1980-07-08
Abstract: The cable sheath clamp consists essentially of a contact plate (1-2-1) which can be easily bent to suit the form of the cable. The middle section (2) has spiky projections (3) which point upwards and are intended to bite into the cable screening (8), which has a tongue (7) cut to accept the width of the middle section (2). The outer two sections (1) of the contact plate (1-2-1) have similar spiky projections (4), which remain uncovered by the cable sheath (6), and point downwards. The contact plate (1-2-1) is formed with the middle section the same depth as the thickness of the cable sheath (7,8) and is inserted beneath the tongue (7,8) formed by the screen (8) and cable covering (7), a metal jubilee-type clamping band being placed around this part of the cable and tightened. This ensures a good electrical connection to the screen and can also be used as a retaining device inside the cable bushing.

Title: Input circuit for hearing-aid amplifier - has changeover switch short-circuiting either microphone or induction coil
Inventor: SKOV ERLING PETER
IPC: H04R25/00
Filed: 1980-09-26
Abstract: The hearing and amplifier input circuit has a change-over switch (S) to select either an electret capacitive microphone (M) or a tele-induction coil (T)(for receiving l.f. signals via a magnetic field). The change-over switch short circuits whichever device has not been selected and thereby reduces cross-talk from the unselected device. The circuit can be attached directly to a telephone loop and used in theatres, lecture-halls, cinemas, churches etc., for the hard-of-hearing. The microphone is coupled via a resistor and capacitor to the input (base) of an amplifier (Q) whose output passes to the hearing aid's main amplifier. The induction coil is connected to the amplifier's emitter. The change-over switch effectively alters the configuration of the amplifying transistor from an earthed emitter (with high negative feedback and low output impedance) to earthed base (with high output impedance).
Patent DE-3038305-A1 (DE)
Inventor: SIEPMANN FRIEDRICH WILHELM DIP
IPC: G01N33/18
Filed: 1980-10-10
Abstract: A process and apparatus for measuring the degree of pollution, the degradableness, and the level of toxicity of aqueous liquids such as effluent. A partial stream is withdrawn from the liquid undergoing examination and diluted with biologically neutral water. The diluted partial stream is oxygenated and continuously flows through a biological bath in a reaction vessel having a constant living mass. The dilution of the partial stream is regulated in such a manner through measurement of the oxygen content upstream and downstream of the reaction vessel, that with constant volume flow through the reaction vessel, the difference between the measurement values obtained remains essentially constant at a predetermined value, so that the amount of dilution serves for the indication of the level of pollution. Additional reaction vessels connected in parallel or in series with the first reaction vessel and having associated oxygen electrodes allows measurement of the toxicity and degradableness of the pollution.
