Title: Door or window drive
Inventor: SOHNS PETER
IPC: E05F15/77
Filed: 1987-01-13
Abstract: The invention is based on a known door or window drive with a motor, controlled with the aid of a computer, and with a plurality of operator control units for controlling the drive from various remote positions. A disadvantage of this prior art is that the mechanical switches used as operator control units cannot be operated independently of one another. The aim of the invention is to simplify the control device of the drive and the operating of the control. This is achieved according to the invention by the operator control units being designed as electronic input units 6 which are connected in parallel and have a keypad (a-f), by means of which control signals in the form of control pulses can be input into the computer, the computer being controllable from any desired input unit 6 by means of the control signal last input in each case. <IMAGE>

Patent DE-3720107-A1 (DE)
Title: Covered blown surfaces for lift production
IPC: B64C39/00
Filed: 1987-06-15
Abstract: As an improvement to the aircraft by Thomas R. Lane from Ohio/USA, but independently of it as well and on my own behalf decades ago (to be precise since 1957) (as evidenced by my documents), I propose covering the blown lift planar surfaces from above, as a result of which an internal flow is produced if the input and output are also connected to the environmental air in an open manner. However, there must be two internal flows, one close above the blown planar surface or curved surface and a second decelerated and slower flow, that is to say underneath the cover, since the effect would otherwise amount to zero internally. There must be suction differences. In addition, no uncontrolled vortexes may occur. This is achieved by fitting a large number of, for example, open chambers, which are positioned slightly obliquely, on the inner surface of the cover. The distance between the suction blowing surface and the cover should be so large that it weakens the flow influences on its own. A compressed-air outlet can be fitted between the chambers and the outer surface of the cover, which compressed-air outlet is fitted in a constricted manner, has a large number of bends and deflections and consists, for example, of a large number of channels of a wound type. This decelerated air, restricted and constricted, is dissipated through channel ends which lead downwards to the underneath of the aircraft. The aircraft of my type is independent of wind and weather and can also continuously change its direction of motion without impeding the suction while additionally having a ram-air pressure and being relatively invulnerable to being fired at.

Patent DE-3735677-A1 (DE)
Title: Rotary resolver
Inventor: WEBER KARL-HEINZ
IPC: G01P3/486
Filed: 1987-10-22
Abstract: Known rotary resolvers for determining the rotational speed and/or the rotational angle of a rotatable part have a rotatably supported shaft on which a pulse disc is mounted. Inside the rotary resolver, a light source and a light receiver are provided. The rotational movement of the pulse disc generates an aoptical signal which is proportional to the rotational speed. The current-conducting components arranged in the interior of the known rotary resolver are sensitive to interference from electrical fields. In the novel rotary resolver, the light source, the light receiver and the electronic evaluating unit are arranged in a separate housing spatially separated from the rotary resolver. The rotary resolver is connected to the light source and/or the light receiver via optical fibre cables. The rotary resolver is particularly suitable for use in locations where there is an explosion hazzard. <IMAGE>

Title: Multi-disc brake subjected to full pressure
Inventor: BAEHRLE FRIEDRICH
IPC: F16D65/853
Filed: 1987-10-28
Abstract: The invention relates to a multi-disc brake for vehicle wheels, especially aircraft wheels, which is subjected to full pressure and is cooled by heat tubes arranged essentially axially. For this purpose, the rotor discs, which, for their part, can likewise be designed as heat tubes, are mounted on a hub, projecting radially inwards beyond the stator discs, which are fixed at the outer circumference. The axial heat tubes lead from the individual rotor discs, to which they are connected so as to conduct heat, to the outside of the wheel, which is exposed to the air. For better heat removal, heat tubes are also arranged in the hub. In addition, the rotor discs and the associated heat tubes can form a single freely communicating heat tube system. In a second proposed solution, the heat tubes are arranged between the stator disc and the inside of the rim and thus, at the same time, prevent heating up of the wheel body. By means of such arrangements of heat tubes, it is possible to remove the large quantities of heat which occur rapidly and effectively from the brake.

Abstract: It is intended to specify a method and a device for testing the reliability of an energised switching operation, it being intended to carry out the testing for conformity with predetermined conditions quickly, with high accuracy and good operational reliability (high operational safety). This object is achieved in that two mutually independent enable signals F1 and F2, which are formed using different methods, are linked to form a switching enable, one of the enable signals also being sufficient for reversionary operation in the event of a defect. The required accuracy is achieved by means of a digitised method, and a high operating speed by rapid recognition of a tendency towards increasing or decreasing correspondence with the specified conditions. Such methods and devices are used in automatic changeover apparatuses for switching over incoming feeders to busbars of switching installations. <IMAGE>

Patent DE-3826750-A1 (DE)
Inventor: LOPEZ VERA LUIS
IPC: A47L15/42
Filed: 1988-08-05
Abstract: A hinge mechanism for attaching a panel 9 to an electrical appliance, for example the door 15 of a dishwasher, comprises a pair of hinges 16, 17 for attachment to the panel 9 at spaced apart points thereon. Each hinge is coupled to the other via a foldable linkage which comprises a connecting rod 5 and angled members 6. The linkage is configured for pivotal attachment to the appliance. The connecting rod 5, angled members 6 and hinges 16 and 17 are pivotally coupled to one another so that an opening force applied to one of the hinges 16 is transmitted by the connecting rod 5 to the other hinge 17 thereby opening the other hinge. When the door is thus opened, the hinge mechanism expands so as to cause the panel to move outwardly and laterally in relation to the door thereby avoiding obstruction of the door during the opening operation. A spring 30 urges the panel 9 towards a closed position. <IMAGE>
