Title: Pressure medium brake system
Inventor: GRAUEL INGOLF DIPL ING
IPC: B60T15/14
Filed: 1981-11-12
Abstract: A pressure medium brake system is proposed in which a relay valve (8, 9) preconnected to the brake cylinders (10, 11, 12, 13) is used to transmit the brake pressure directly and by a short route from a pressure medium source (storage reservoir (5, 6)) into the brake cylinders (10, 11, 12, 13). The relay valve (8, 9) has two possible means of actuation, one by means of a solenoid valve (18, 19), which receives a current when the pedal is operated, and the other by means of control pressure from a pedal-operated brake pressure transducer, for example in the case of compressed air as pressure medium from a pedal-operated brake valve (7). The pressure medium brake system is preferably used on commercial vehicles. <IMAGE>
Patent DE-3146824-A1 (DE)
Inventor: REUTTER HEINRICH
IPC: B65D51/00
Filed: 1981-11-26
Abstract: In order to place a sealing cap, which is to be placed in particular on a filler neck of a gasoline tank, on the neck so as to preserve the seal with little actuation force but so that it seals securely, the sealing cap is equipped with a turning lifting apparatus (24, 43) which effects a pressing of the sealing ring (4) at the free neck end (5) when the turning stop (26) of the sealing cap encounters the counter stop (27) of the filler neck (1). A pressing member (23) is displaced in the axial direction against the resistence of a compression spring (25) in the turning stop (26) via the turning lifting apparatus and simultaneously moves a radial outer collar which is coupled with the turning handle (2) in the displacement direction and which is contacted by the sealing ring (4) against the free neck end (5), whereby the sealing ring is pressed together. By means of an indicator window (54) one can read off the fully closed position of the sealing cap with certainty. An interior pressure which is too high or a vacuum can be prevented by means of pressure and vacuum relief valves.

IPC: H04Q9/16
Filed: 1981-12-18
Abstract: An interrogating device (3) is connected to a number of signalling devices (1) which are each allocated to a switch (S) to be monitored. Each signalling device is provided with an address and outputs direct-current pulses of different width after having been selected by the interrogating device for identifying the position of the associated switch. The signalling devices are connected to the interrogating device in parallel connection via a two-wire line (2) which is used both for supplying the signalling devices with current and for transmitting the information signals. The number of the interrogating pulses output by the interrogating device corresponds to the highest address. Each signalling device is provided with a rechargeable power supply which is fed via the connecting line and disconnects its load from the line after having received each interrogating pulse. <IMAGE>

Patent DE-3215448-A1 (DE)
Title: Time-division multiplex system
Inventor: BADER EDGAR DIPL ING
IPC: H04J3/14
Filed: 1982-04-24
Abstract: In time-division multiplex systems with data channels, a data user which uses a 64 kbit/s channel in a pulse frame corresponding to CCITT Recommendation G.732 or G.738 can stimulate unintentionally or even intentionally the frame alignment signal. A failure of frame synchronisation occurring at this time can therefore lead to the channels being wrongly allocated in the demultiplexer. To prevent this, the multiplexers of the multiplexing devices insert a confirmation signal into the time-division multiplex signal if frame synchronisation exists in the associated demultiplexer. In addition, channels containing user signals are blocked in the multiplexers if their associated demultiplexer does not receive a confirmation signal from the remote multiplexer.

Patent DE-3220738-A1 (DE)
Title: Thermally operated switch
Inventor: RAY WILLIAM A
IPC: H01H37/48
Filed: 1982-06-02
Abstract: The switch which can be operated thermally comprises an active unit which comprises an element (60) which responds to heat and is a component of a sheath (72) into which electrical heating resistance elements (78, 79) are inserted. Heat is released internally from the sheath (72), while cooling takes place by heat dissipation on the outside of the sheath (72). The element (60) which responds to heat has the shape of a flat plate which can expand in the longitudinal direction. This plate engages with the shorter arm (104) of a lever (100) which is supported such that it can pivot, is bent at right angles and engages via a leaf spring (141) with the operating element (50) of a switch (40) which is to be operated. <IMAGE>

Title: Pressure-operated volume exchanger of compact design
Inventor: TUTTASS EDMOND ING GRAD
IPC: E21F3/00
Filed: 1982-07-16
Abstract: A pressure-operated volume exchanger, in particular for exchanging high-pressure cold water and low-pressure warm water in underground air conditioning systems, consists of a plurality of tube chambers which are connected in each case via valves to the assigned feed and discharge lines. The tube chambers are arranged vertically and are to be connected at top and bottom by a multiway valve. This multiway valve is constructed as a disc lock and successively connects all the tube chambers to the cold water or hot water line. The disc locks are rotatable and can be controlled via an actuator. However, it is also possible to connect the disc locks rigidly to the feed lines, and instead of this to construct the tube chambers arranged therebetween in a rotatable fashion. This results in a very favourable compact design of the entire pressure-operated volume exchanger.
Patent DE-3231309-A1 (DE)
Title: Bromine-vapour gas engine
Inventor: KIRRWALD HEINRICH DIPL ING
IPC: F01K25/08
Filed: 1982-08-23
Abstract: The medium of bromine is heated, compressed and expanded after leaving the turbine nozzle. Thereafter, renewed liquefaction of the medium of bromine is performed in a special condensing region. The condensate runs back under the influence of gravity to the bottom trough and is once again heated and evaporated there. This is performed by a permanent circuit similar to that of water. The energy required for heating is supplied to the bottom trough with the aid of heat exchangers. After working dissipation to the turbine, this energy is once again completely destroyed after the expansion and condensation. The essential components of this drive system are 1. spec. weight = 3.14 and 2. boiling point at approx. 59 DEG C. A pressure of 9300 bar can be generated given a design height of 30 m. 1. Energy production without primary energy. No stress on environment. No costs for transport and delivery of oil, coal, gas, uranium or the like. The drive is performed using solar energy, collector greenhouse with large energy roofs - 25 km<2> - waste heat from coal-fired and atomic power stations or, e.g., the heat from refuse incineration plants. Hot springs and geothermal energy are also possible. 2. The plant is suitable in particular for installation in updraught power stations. 3. A further decisive "plus" is the possibility of installation at the site of very expensive large cooling towers. Instead of the destruction of energy in cooling towers, in bromine gas turbines the exhaust heat is forced to do further work and thus converted in an environmentally kind and profitable fashion. <IMAGE>

Title: Cylinder head gasket for internal combustion engines
Inventor: MAUS KARL HEINZ
IPC: F16J15/12
Filed: 1982-11-18
Abstract: In cylinder head gaskets preferably made of relatively deformation-resistant materials, such as sheet-metal plates or possibly impregnated plates of soft material, the collecting channels surrounding the combustion space openings on one or both sides and the diversion channels leading from there radially outwards to the sealing edge and intended for taking up and carrying away combustion gases passing over from the combustion space are formed from layers of elastomers or plastics. The channels are reinforced by depressions or beads stamped in between the layers, the interaction of the layers and the depression thus preventing the compression of the channels under the sealing pressure in an effective manner. <IMAGE>
