Patent DE-3504268-A1 (DE)
Title: Valve with pilot control
Inventor: MUELLER PETER
IPC: F15B13/04
Filed: 1985-02-08
Abstract: The valve has a main piston displaceable against the force of a spring. The spring surrounds an axially extending actuator arranged on the main piston and is supported on two spring plates. The spring plates are each supported on the valve housing. The first spring plate additionally bears against the main piston and the second spring plate bears against the actuator. In addition, the second spring plate bears against a stop which is mounted on the valve housing, is adjustable relative to it in the axial direction of the piston and can be locked in any setting position relative to the valve housing. The bracing of the spring can be set merely by axially displacing the stop and re-setting the actuator.

Title: Biological ventilation of rooms
IPC: F24F7/007
Filed: 1985-07-12
Abstract: There must be ventilation, but how? For a time, it was believed that air should be supplied to the person by heating wires and pipes until this turned out to be a fallacy. This makes a person ill. For this reason, by means of electronically controlled flaps, the air is to flow in directly from outside and be drawn off at the floor at the wall, the drawing-off is to be interrupted on opening a door or a window leaf, the rate of the drawing off is to be so weak that no annoying draught arises, the drawn-off air is to be compressed in a rotating funnel with a thread and cooled on the outside and the air, which cools again on relief, is to be used for cooling purposes.

Title: Pressure-operated brake cylinder
Inventor: SIEBOLD MANFRED
IPC: B60T17/08
Filed: 1986-02-01
Abstract: The proposal is for a pressure-operated brake cylinder, the piston rod (6) of which has a stop which ensures that the end (9) of the piston rod always protrudes by a certain amount from the cylinder. The stop is formed by a continuous annular washer (11) anchored in the circumferential surface of the piston rod (6) and by a longitudinally split guide screw (13) which is mounted on the piston rod (6) after the assembly of the brake cylinder and is anchored in the cover hole (10). This makes it possible to produce an inexpensive stop which makes it easy to cope with the length tolerances for the protruding length. <IMAGE>

Title: Arrangement for knowledge-based classification of datasets
Inventor: KELLNER ALBRECHT DR RER NAT
IPC: G06V30/194
Filed: 1986-06-06
Abstract: An arrangement for parallel and therefore time-saving processing of data of any kind. In this arrangement, individual features of the data-capturing sensors (10) to (19) are present, and communicate by means of a knowledge base consisting of a matrix Mik with those elements (20) to (27) of a global classification level which contain the corresponding features. From the number and/or intensity of the signals which are output by the sensors, relative cumulative intensities or pulse counts are formed in registers (30) to (37) with the matrix Mik, and the register contents are compared to each other in a comparator (40). A signal output device (50) displays the address of the register which has reached the highest value. The arrangement is capable of learning, because the Miks are set or activated according to the recognition event which has previously been carried out. The arrangement is suitable, for example, for image recognition for diagnostic systems, and for observing sizes which change with time. <IMAGE>
Patent DE-3622760-A1 (DE)
Title: Diving apparatus for model submarines
Inventor: SCHAFFER ANNI
IPC: A63H23/04
Filed: 1986-07-07
Abstract: An apparatus is described for the problem-free diving and surfacing of model submarines, especially for models with a low space requirement, which apparatus moreover has the advantage that, because of the simple structure of the apparatus, it is possible to dispense with additional electronics for trimming the model submarine. The diving apparatus is so designed that two water tanks can be flooded or blown with the aid of two gear pumps. An ascending pipe regulates the necessary volume of water in order to achieve a predetermined depth of dive. Switching off the gear pumps is not necessary, since excess water passes back to the outside through the overflow pipes, as a result of which no excess pressure can arise in the interior of the boat. During surfacing, non-return valves close the overflow pipes, the flexible water tank contracts somewhat, and as soon as the model reaches the surface of the water with the top of its conning tower air flows into the water tanks and the pressure balance in the interior of the boat is again restored.

Patent DE-3628299-A1 (DE)
Inventor: OPPER MANFRED DIPL ING
IPC: G06F11/16
Filed: 1986-08-21
Abstract: In normal operation, the two loop buses convey data in opposite directions in parallel and in a redundant manner, one channel of each computer being allotted respectively to one bus by means of active bus couplers. In the event of an anomaly the buses are interrupted cyclically in sections in order to locate the faults, and transverse connections are established with the other respective bus. After the defect has been located, the adjacent sections are transferred continuously to a single-loop structure without redundancy, the faulty section being separated. At the same time, for the control of the two buses, an active control station is planned which hierarchically manages the rights to access to the bus for the other bus sharers who have their own computer, and compares in a cross-manner by means of appropriate monitoring functions, the data circulating in one bus in relation to the transmission data in the other bus and vice-versa. Non-agreement reveals an anomaly which results in switching to the test mode, in which the control station cyclically calls up the sub-stations; activated bus couplers grouped respectively in pairs in bus control units progressively effect breaks and transverse connections, until a non-agreement between the data emitted and data received inside the control station indicates the location of the fault, which leads to switching into the ''FAULT'' mode.
Patent DE-3635329-A1 (DE)
Inventor: DIJKHUIZEN OKKO K
IPC: A61H33/00
Filed: 1986-10-17
Abstract: The invention relates to a cleaning device for a piping system of a whirlpool tub where one or more outlet valves supply water and/or air into the interior of the tub. The outlet valves branch off from a cleaning-fluid circulation system using a delivery pump to circulate the cleaning fluid. When the cleaning fluid is circulated the outlet valves are in a closed position, receiving a flow of the cleaning fluid, but preventing the issuance of the cleaning fluid into the tub interior. The outlet valve has a water-supply line connecting into a water-distribution chamber disposed in a valve body, from which a water-outlet channel branches toward the tub interior. The water-outlet channel guides, in a watertight and axially movable manner, a sealing member passing through the water-distribution chamber. The sealing member has a smaller cross section than the water-distribution chamber, and an end face of the sealing remember, when in a closed position, is precisely flush with or bulges just slightly beyond an adjoining end face of the valve body.

Title: Device for dosing liquid
Inventor: VAEYRYNEN JAAKKO DIPL ING
IPC: G05D7/01
Filed: 1987-02-03
Abstract: This invention relates to a device for dosing liquid. The device comprises a closed container (1) which contains liquid (2) and in which a feed pipe (3) extends from the bottom of the container into an open vessel (4) situated below the container. When the liquid surface (6) in the vessel falls below the lower end of the feed pipe (3), new liquid can flow from the container (1) into the vessel. Such known devices cause disturbing noise if air is sucked into the container (1) between the lower edge of the feed pipe (3) and the liquid surface (6). Disturbing noises can be avoided by the feed pipe (3) being surrounded by an outer pipe (7), the lower end of which is at a lower level than the lower end of the feed pipe (3) and by the air space (8) between the pipes being separated from the environment by means of a piece (9) made of porous material which has a great air-flow resistance. <IMAGE>
