Title: Hospital bed with a resting surface with adjustable height and inclination
Inventor: DEHNE HEINZ
IPC: A61G7/015
Filed: 1985-05-04
Abstract: In a hospital bed the resting surface is adjustable in height and inclination relative to the subframe, and for this two lifting linkages are used which each engage on one of two parallel shafts in the subframe. The two shafts are normally connected to one another so as to be jointly rotatable via a toothed rack, one bearing end being pivotably mounted on a connecting arm connected to the first shaft, whereas the other adjusting end which has the toothing can selectively be introduced with a gap into a bearing pin sitting on a connecting arm firmly connected to the other shaft. The inclination of the resting surface is adjusted using a decoupling lever which can be twisted via a Bowden cable. The decoupling lever engages so as to be displaceable in the longitudinal direction over a sliding piece on a guide rail fixed along the toothed rack, and lifts the effective gap out of the bearing pin. In order to achieve a wide range of adjustments and to permit troublefree decoupling of the toothed rack on the bearing pin it is proposed that the bearing pin forming the coupling be used at the same time for rotational mounting of the decoupling lever.

Patent DE-3543353-A1 (DE)
Title: Clamping device
Inventor: ANTONI HERBERT DIPL ING
IPC: B25B5/14
Filed: 1985-12-07
Abstract: The invention relates to a clamping device with a multiplicity of clamping elements, arranged in at least one clamping plane and movable or operable independently of one another, for clamping extremely thin-walled workpieces with little deformation, in particular channels and tubes. In order to be able to clamp such deformation-sensitive workpieces in a compensative manner without considerable deformation, two alternative solutions are proposed. In the first solution, a sensor is allocated to each clamping element. Upon operation of the clamping elements, the sensor detects an approach of the individual clamping elements to the workpiece or contact, virtually without force, of the individual clamping elements with the workpiece and cuts off the respective clamping-element drive before all clamping elements are subsequently actuated simultaneously for building up the clamping force for the clamping of the workpiece. In the second solution, each clamping element is divided into a base part, which can be operated by a central drive allocated to all clamping elements, and into a clamping part which can be displaced against the force of a spring by a predetermined compensating distance relative to the base part and can be clamped to the base part in any position within the compensating distance.

Title: Method and device for monitoring electrical loads
Inventor: FORTKORT KARL-HEINZ
IPC: H05B37/03
Filed: 1986-05-16
Abstract: In the case of a method for monitoring electrical loads, in the case of which the voltage drop across a control resistor which is connected in series with the parallel circuit of at least two electrical loads is compared with limit values and in the case of which display means are operated, the electrical loads are briefly and successively switched off and switched on again in order to monitor a large number of electrical loads having very different power consumptions once a predetermined time interval has elapsed after the connection of an electrical load and in the event of a deviation of the first voltage drop from a first limit value. A second voltage drop is then compared with a second limit value with the first load switched off, a third voltage drop is compared with a third limit value with the second load switched off and display means are operated in the event of a deviation of the second voltage drop from the second limit value and/or in the event of a deviation of the third voltage drop from the third limit value.
Patent DE-3616703-A1 (DE)
Title: Apparatus for treating, in particular fining, juices and wine
Inventor: PAULY DIETMAR
IPC: A23L2/70
Filed: 1986-05-17
Abstract: Three vessels with lines and valves and an electrical control box and a frame having an electric motor and stirrer are arranged on a base plate. In the vessels, the finings are stirred with the automatically precisely meterable amount of water for the exactly required times. The contents of the vessels are successively emptied into the tank and there mixed with the fruit juice or wine to which enzymes, if required, were previously added. The emptying of the vessels is controlled by the control box via a program controller. The tank stirrer is automatically switched off after a preset time and the tank contents are subjected to a standing time. After being emptied into the tank, the vessels can be flushed immediately and refilled with finings and water. The compact association of all associated devices, the exact metering of the water, exact control of the times etc., achieves an economical water consumption with simultaneous fault-free separation of the finings, optimum finings consumption etc.
Patent DE-3618481-A1 (DE)
Title: Method for optimising passive safety in the operation of a nuclear reactor
Inventor: SCHUBERT WERNER DR MED
IPC: G21C1/00
Filed: 1986-06-02
Abstract: Particularly given incalculable accidents due to the physicochemical principle of the nuclear reactor in conjunction with the release of considerable energy, there is a need, above all, to optimise passive safety in the region of the nuclear reactor. In order to avoid very severe accidents at a nuclear power station accompanied by secondary damage over wide areas, relatively small nuclear reactor units are to be as far as possible inserted in the ground distributed in spatially offset bunkers, and the openings of each bunker are to be permanently sealed. It is possible within the bunker itself to provide further protective devices against eruption and explosion - depending on the internal system of the reactor. These devices absorb forces due to the effects of pressure flushes. Gas-filled bags or cushions, for example, are to be used for this purpose, and can be mounted on the side walls of the bunker. Such a device is mostly useful only in the case of a single pressure flush. Additional walls with numerous wall penetrations are also suitable for reducing numerous pressure flushes which are not too strong. Dry sand raised above the bunker in a suitable container is to be held ready for the most serious accident with a nuclear reactor which is in an MCA, so that a runaway nuclear reactor which is no longer capable of repair can be "buried" in a few seconds.

Patent DE-3625421-A1 (DE)
Title: Ventilating fan arrangement
Inventor: SCHMIDT MARTIN DIPL ING
IPC: F24F7/013
Filed: 1986-07-28
Abstract: An axial fan (L) is fixed from the outside of the housing to a wall (W) of a housing by attaching the fan motor in the centre of a web plate (SP), which is of circular construction, the radius of the web plate (SP) being grater than the radius of the fan blade. Provided at the edge of the web plate (SP) are two sets of tab-like projections (V1, V3, V5 and V2, V4, V6, respectively), each set of which can be inserted into an opening (OE) in the wall (W) accommodating the web plate (SP) with a shape adapted therefor, the respective other set limiting the penetration depth so that in a subsequent rotation of the web plate (SP) into a locking position, the respective first set causes the web plate (SP) to bear against the wall (W). The mounting or dismounting of the axial fan thus takes place with little technical complexity, in the same way as with a bayonet catch. <IMAGE>
Patent DE-3629016-A1 (DE)
Title: Peristrophic engine
Inventor: KOUTSOUPIDIS THEODORE
IPC: F02B75/32
Filed: 1986-08-27
Abstract: The invention is intended to increase the output power of an internal combustion engine by increasing the torque and reducing the friction and the masses in the engine. The torque is increased by increasing the distance between the masses (webs) and the main journals by arrangement of these on the outermost ends of the connecting rod and a triangular ball bearing (lower part of the piston). The friction is reduced by using ball bearings (>>peristrophic balls<<) in all moving parts. The weight of the engine is reduced by replacing the weight of the crankshaft with ball bearings (peristrophic balls I, II, III >>). The sole function of the crankshaft in the engine lies in holding the connecting rod of the piston. The inertial weight is necessary for a uniform rotary movement of the piston and is transmitted to the connecting rod and the <<triangular ball bearing>> (lower part of the piston). A partial transmission of the inertial weight from the crankshaft to the connecting rod and the lower part of the piston has the effect of increasing the torque of the engine. An <<Eso cylinder>> and <<Exo cylinder>> are intended to replace existing cylinders. Their function is to increase the life of the cylinders themselves and to reduce the heat loss through the cylinder after combustion.
