Patent DE-2555314-A1 (DE)
Title: Adhesive strength testing equipment - indicates efficiency of bonding by detection of electrical impedance variation between layers
Inventor: OTT ALBERT DIPL ING
IPC: G01N27/82
Filed: 1975-12-09
Abstract: The tester consists of a ferro-magnetic ring (8) with an exciter winding (10). The winding is energised with AC to produce an alternating magnetic field. The magnetic ring is surrounded by an electrically conducting sheath (12) which is in contact with the surface of the material (13). A cylindrical rod of plastics material (14) passes throught the centre of the test head, the lower end being in contact with the material. The upper end is fitted with a piezo-electric transducer (15) energised by an AV of lower frequency than that of the electromagnet. In areas of poor bonding, the varying resistance due to the vibration produced by the transducer, amplitude-modulates the exciter winding. The degree of modulation is proportional to the efficiency of the bond.

Title: Speed controlled DC motor protection circuit - has diode switching in ballast resistor when motor acts as generator
Inventor: KOSTMANN HANS
IPC: H02H7/08
Filed: 1976-02-21
Abstract: The protection circuit, for a speed-controlled dc motor supplied via a thyristor rectifier with energy return, has a diode (2) connected between the motor (3) and the rectifier (1) and forward biased when the motor is acting as a motor. The ballast resistor (4) used when the motor is working as a generator is therefore only effective when the motor is actually generating current. The rectifier consists of two antiparallel thyristors and is coupled to the ac supply. The ballast resistor, shunted by the diode, protects the generator from short circuit currents.

Title: Electromechanical beam deflection system - directs beam to two parallel mirrors to obtain parallel shift by changing mirror spacing
Inventor: MATTHAEI RALF
IPC: G02B26/10
Filed: 1976-03-04
Abstract: An i.r. visible or u.v. light beam is directed at an angle to the reflecting plane. It reaches two parallel mirrors or reflecting plates which are spaced opposite one another or at an angle. These anges are such that by changing the spacing of the mirrors by a certain amount of parallel shift of the emergent beam is achieved. The change is made by movement caused by electrostatic, electro-mechanical, hydraulic, acoustic or thermal forces or by a combination of several such forces. This light spot control can be used in projectors, image displays, t.v. and oscillograms.

Title: Slatted blind for irregularly shaped windows - has unequal length slats pivotally mounted in brackets, and tilted by cord passing over top pulley
Inventor: BRUEGGEMANN MANFRED
IPC: E06B9/24

Title: Digital reproduction of two=dimensional curves - uses integrated circuit counters and logic enabling optional abscissa intervals
Inventor: HAVEL JIRI DIPL ING
IPC: G01R13/02
Filed: 1977-07-27
Abstract: A device (1) is designed for digital reproduction of two-dimensional curves using integrated circuitry. It enables optional abscissa intervals within defined limits to be used. It may be produced considerably more cheaply than computer or storage devices. A first digital counter for the curve abscissa variable receives generator pulses on its count input and its output activates two pulse generating circuits contg. logic gates. The first counter outputs are decoded and recombined such that the pulse generator logic circuits are each associated with successive counter condition regions. The pulse generating logic circuits are only activated when the corresp. counter condition prevails. An ordinate variable counter is controlled by the logic circuit pulses and is connected to an evaluation unit.

Title: Meter showing fuel used at various vehicle speeds - consists of manometer connected to fuel supply via T=junction to measure under-pressure in suction lead
Inventor: BUMILLER WALTER
IPC: G01F9/00
Filed: 1977-08-10
Abstract: The 'optimeter' shows the smallest amt. of fuel used in a motor vehicle at all possible speeds so that the optimum use of fuel can be ascertained. A low pressure is produced in the suction lead by a fuel pump. This low pressure is more pronounced the more fuel is needed. This under-pressure is measured by a manometer which is connected to the fuel supply via a T junction piece. This can be inserted by the layman on any type of vehicle without the necessity of changing either the carburettor or the fuel lead.
