Patent DE-3227154-A1 (DE)
Title: Positive rail
Inventor: QUANTE HEINRICH
IPC: B66C7/08
Filed: 1982-07-21
Abstract: A positive transmission of the drive force from the monorail conveyor drive to the rail is provided in particular in the case of the so-called European standard rails 140 E if the bottom flange in these rails is designed at the side like a toothed rack. By the formation of the toothed rack on or in the bottom flange of the conventional rail, it is possible to use these rails with the conventional rails without a toothed-rack design, since the same connecting elements are used in both. In addition, the rail enables drives to be used only with positive drive, for example via a rotating chain which engages in the teeth or tooth gaps in the bottom flange, or else combined drives of friction and positive drive. The effective area between the teeth or tooth gaps and the chain can be increased by the bottom flange of the rail being strengthened, though with the otherwise conventional dimensions of the rail retained. <IMAGE>

Title: Centrifugal-force switch for limiting or switching-off an internal-combustion engine
Inventor: STIPEK THEODOR DIPL ING DR
IPC: H01H35/10
Filed: 1982-09-06
Abstract: A centrifugal-force switch for limiting or switching-off an internal-combustion engine has, on or in a shaft (1) of the same, a bush (4) which is screwed into a radial threaded hole (3) and in whose longitudinal direction a flyweight (7) is guided in a movable manner, which flyweight (7) is pretensioned, with its centre of gravity, by means of a spring (10) in the direction towards the axis of the shaft (1). The movement capability of the flyweight (7) in the bush (4) is limited by stops. In order to adjust the response sensitivity, the eccentricity of the centre of gravity of the flyweight (7) located in its inner position can be adjusted by rotating the bush (4) in the threaded hole (3). When the flyweight overcomes the force of the spring (10), under the influence of the centrifugal force, and reaches its outer position, it operates an electrical switch (12). <IMAGE>

Patent DE-3237208-A1 (DE)
Inventor: TANNHAEUSER ROLF DIPL ING
IPC: G01R31/319
Filed: 1982-10-07
Abstract: When testing a unit under test, for example, a card module, check characters must be transmitted to the unit under test from the tester via connector elements. One selection device per connector element is provided in order to be able to transmit the correct check character over the correct connector element. Each selection device contains addresses of the check characters which are to be transmitted over the allocated connector element in an address register. During the test event, the assistance of a comparison device is employed in order to determine whether the addresses contained in the address register coincide with the addresses of check characters which are supplied by an input bus. Given equality, the allocated test signal is transmitted to the connector element. When a plurlity of check characters are allocated to one address, one of the check characters can be selected and transmitted to the connector element with the assistance of a multiplexer given equality of the addresses. Since respectively those check characters which are to be transmitted over the connector element are selected by a changeable address stored by the associated selection device, the check characters allocated to one address can be selected by a plurality of selection devices. The number of machine words comprised of address and allocated check character required per test operation is therefore considerably reduced.

Title: Method for optimising the contrast of field-effect liquid crystal cells
Inventor: CREMERS ROLF A DR
IPC: G02F1/1335
Filed: 1983-03-23
Abstract: A method for optimising the contrast of field-effect liquid crystal cells without having to depart from the technically proved, cost-effective technology for the production of large-area liquid crystal display devices having negative contrast representation, such as are applied, in particular, for motor vehicle instrumentation, consists in measuring for a given cell with liquid crystal filling that transmitted light wavelength at which the cell driven electrooptically to block passes through a minimum in its characteristic of the residual transmission over the light wavelength, that is to say experiences maximum absorption. The transmission operation of the liquid crystal cell is then performed by means of light in the spectral region about this wavelength, which light is filtered out from the light of an illuminating arrangement by means of a colour foil. The temperature dependence of the residual transmission is decisively reduced if a dichroitic dye is added at low concentration to the liquid crystal material, being chosen in accordance with the transmitted light colour. Pole filter pairings which optimally block for the light wavelength previously determined can be selected experimentally for the purpose of further contrast optimisation.

Title: Low-temperature heater
Inventor: LEVACHER FRIEDRICH KARL DR
IPC: F28D1/02
Filed: 1983-10-25
Abstract: The invention relates to a low-temperature heater having flat profiled bodies intended for transporting a liquid heat carrier, and having a number of heat exchanging parallel tubes. The object consists in optimising the flat profiled bodies of the low-temperature heater to such an extent that thermal conduction to the upright heat exchange tubes is improved, and in the process the use of further operating modes is made possible. The solution is seen in a flat profiled body (1) having a rhomboid profile, whose maximum height (h) is dimensioned such that it is possible in this region to introduce a further longitudinally extending bore (3) in the flat profiled body (1) so that an additional use, e.g. as an electric heater or as a cooling unit for room air conditioning, is possible with the aid of this bore (3). Low-temperature heaters are operated with a heating medium temperature of approx. 45 DEG C, and can thus be used in economic energy supply systems such as combined heat and power, industrial waste heat, heat pumps or solar collectors. <IMAGE>
