Patent DE-2656134-A1 (DE)
Title: Single phase asynchronous machine - has auxiliary phase capacitor connected to resonant circuit blocking current flow when machine is stationary
Inventor: AKBAR SAMY DIPL ING
IPC: H02P1/44
Filed: 1976-12-10
Abstract: The auxiliary phase for starting and operation is in series with a capacitor. It is connected as a variable voltage source to an oscillating circuit. Its voltage is min. when the machine is stationary, and max. when running without load. Its inductive and capacitive reactances have a blocking effect at min. voltage, when a certain saturation of the inductor iron core is produced. It is due to the adjustment of the reactances causing the current from the auxiliary phase capacitor being nearly zero. At high speed, when iron core saturation is high and the resonance effect abruptly disappears, no more blocking effect is produced. The capacitor (4) can now discharge through the oscillating circuit (5, 6) or through its inductance, so that control of its charge permits the capacitor to retain its capacitive properties. It behaves like a capacitor during starting and normal operation.

Title: Communications cable with HV overhead line - is optical fibre and/or insulated copper conductor inside hollow line conductor
Inventor: RAMONAT DIETER
IPC: H01B11/00
Filed: 1977-07-26
Abstract: The high voltage overhead line has individual wires laid around a central tensile load carrying core. The insulated communications cable is threaded through one of the wires which is hollow. It can be pulled clear at points where it is necessary to make a splice or terminal. The cable may be an insulated copper wire or an optical fibre. Alternatively a metal core may be included with a light fibre for supplying power to optical repeater amplifiers along the cable.

Title: Crystal fault reduction - in semiconductor single crystal layers by coating rear with non:monocrystalline layer
Inventor: BURTSCHER JOACHIM DR
IPC: H01L21/203
Filed: 1977-08-24
Abstract: Crystal defects can be reduced during the mfr. of semiconductor devices and integrated circuits in the monocrystalline Si wafers below the surface where the switching systems are introduced. Before process operations such as high-temp. oxidn. of diffusion, a not monocrystalline (polycrystalline or amorphous) semiconductor layer, 0.5-5 mu thick, is applied to the reverse side. This is a technologically much simpler process than phosphorus doping and achieves at least the same reduction rate of crystal defects as the former.

Title: Automatic fluid metering equipment - has inflowing air jet with anemometer circuit resistance controlling fluid outlet valve
Inventor: LEIFERMANN WALTER
IPC: A47J31/40
Filed: 1977-10-27
Abstract: The equipment automatically meters quantities of fluid, having a vessel accommodating the fluid with a bottom outlet and valve. The vessel (10) has a top cover (15) with an inlet union (21) for pressure equalisation by means of inflowing air. There is a jet-type opening (20) of predetermined cross-section in the union. It contains the resistance unit (30) of an anemometer circuit (40). At the output of this a voltage appears proportional to the flow speed and thus to the quantity of air, and is fed to the input of an analogue/frequency converter, emitting an alternating voltage or a succession of impulses of frequency proportional to this voltage. This is supplied toa counter circuit (60) for comparison with a reference value predetermined by an adjuster (70). The output of the counter circuit supplies a circuit (80) controlling the electrically-operated outlet valve (12).

Title: Supermarket transporter trolley with lockable wheels - locks one pair of wheels and then releases them for easy manoeuvring of stack
Inventor: WENCK REINHARD
IPC: B62B5/04
Filed: 1978-01-20
Abstract: The transporter trolley for supermarkets is operated by a walking person. Trolley wheels are pivoted about a vertical axis. Trolleys are nested for stowing. The trolley has reliable wheel tracks. The trolley wheel vertical pivot axis has adjacent pivoted bar (8) which prevents a pair of wheels (3) from pivoting about vertical axis. This mechanism, however, is released when the trolleys are pushed into each other. Hence the horizontally stacked trolley assembly is highly manoeuvrable. The pivoted bar mechanism can be fitted to both rear wheels of a trolley.

Title: Piston with wear-resistant coating - consisting of molybdenum applied by flame spraying with gun at angle to form sloping sides
Inventor: BEYER HORST DR ING
IPC: F16J9/00
Filed: 1978-01-27
Abstract: An anti-friction and wear resistant surface is deposited onto components such as pistons by the flame spraying of atomised molybdenum. A groove (10) with sloping sides (7) is machined in the component and the molybdenum is then flame sprayed by holding the spray gun at an angle so that the sides of the molybdenum layer (2) slope away from the sides of the groove (10). This gap reduces the tendency of the molybdenum to break away from the surface of the component. The component may be copper plated before spraying in order to increase the adhesion of the molybdenum.

Title: Packed foodstuff automatic roasting process - simultaneously perforates sealed bag, which is pref. of polyester
Inventor: SCHMIDT HENNING
IPC: A23L5/10
Filed: 1978-02-03
Abstract: The process is for automatic roasting of packed foodstuffs, such as toast or sandwiches. In conjunction with the roasting operation a perforation is effected of the hermetically sealed bag in which the food is packed. This can be done immediately before starting the roasting operation. The food is pref. packed in roasting sheet of polyester material and heated to a temperature at which the sheet tears and shrinks to expose the contents, which are then further heated to complete the roasting. This heating can be carried out in a first phase to a maximum level, followed by a second one at a reduced level, radiant heat being used, combined with hot air.

Title: Fork lift truck - has engine driven battery powered auxiliary drive for quiet short operations
Inventor: ZOLLMEYER WILLI
IPC: B60W20/00
Filed: 1978-02-10
