Patent DE-3238106-A1 (DE)
Title: Pressure-regulating valve
Inventor: SCHLOTT WALTER ING GRAD
IPC: F02M69/54
Filed: 1982-10-14
Abstract: A pressure-regulating valve which serves for the temperature-dependent and time-dependent regulation of the pressure of a fluid is proposed. The pressure-regulating valve comprises a diaphragm (10), on which a valve spring (18) acts in the closing direction of the valve (1) towards a fixed valve seat (6) via a transmission pin (16) and a spring plate (17). The transmission pin (16) has a U-shaped connecting part (19), to which a stud (20) engaging on the spring plate (17) is connected. Provided coaxially with the stud (20) on the connecting part (19) is an actuating part (21) which acts on the diaphragm (10) via a support (13). A head (23) projects into the connecting part (19) and is aligned coaxially with the stud (20). Between the legs of the U-shaped connecting part (19) projects the free end (28) of a bimetallic spring (27) which is fastened at the other end to a bolt (25). The bimetallic spring (27) can be heated by an electrical heating element (30). Below a specific temperature, the free end of the bimetallic spring (27) bears against the head (23) and reduces the force of the valve spring (18) on the diaphragm (10). <IMAGE>

Title: Motor vehicle with a payload space and an internal combustion engine
Inventor: STOLZ ALBERT DIPL ING
IPC: B60H1/24
Filed: 1983-02-08
Abstract: In motor vehicles with a payload space and an internal combustion engine, the exhaust air is normally conducted out of the payload space into the open air so that its heat content is lost, whilst the combustion air which is sucked out of the engine space is too warm in the summer and too cold in the winter. In order to avoid these disadvantages, according to the invention, the exhaust air from the payload space is fed to the internal combustion engine as combustion air, the exhaust air which is heated in the winter and often cooled in the summer corresponding to the requirements with respect to the temperature of the combustion air. If the exhaust air is heated up by the exhaust gases of the internal combustion engine and subsequently heats the air fed to the payload space, it serves additionally as an intermediate carrier for the heating of the payload space.
Patent DE-3307176-A1 (DE)
Title: Control method for withdrawing a cast strand from a mould in horizontal continuous casting and a device for carrying out the method
Inventor: SKORMIN ALEKSANDR F
IPC: B22D11/20
Filed: 1983-03-01
Abstract: The control method for withdrawing a cast strand from a mould in horizontal continuous casting consists in monitoring the wall temperature of the mould (2) in the initial formation zone of the shell of the solidified strand, which changes periodically with the frequency of the withdrawal cycle. The withdrawal process is interrupted if the wall temperature of the mould (2) does not fluctuate at the frequency of the withdrawal cycle as the mould wall temperature simultaneously drops. The interruption time of the withdrawal process is in this case prolonged by a factor of at least two relative to the time period of the preceding withdrawal cycle, in order to reestablish the shell of the strand (3). The control device for the withdrawal of a cast strand from a mould in horizontal continuous casting contains a temperature sensor (1) for the mould wall, which is arranged in the initial formation zone of the shell of the strand (3) and is connected electrically, via a recorder (4), to a control unit (5) of the drive of the withdrawal means. The device furthermore contains a transmitter (10) for monitoring the condition dependent on the change in the mould wall temperature, which is connected by one terminal (11) to the temperature sensor (1) for the mould wall temperature and with the other terminal (12) to the control unit (5) of the drive of the withdrawal means. <IMAGE>

Title: Track circuit for track monitoring in railway safety systems
Inventor: BRECHMANN GERHARD DIPL ING
IPC: B61L1/18
Filed: 1983-03-07
Abstract: Track circuits, in conjunction with an evaluation circuit for two voltages, one of which varies as a function of the clear and occupied state of the respective track section (GS), serve to monitor tracks in railway safety systems. Synchronously controlled switching devices (G1, G2) are provided which draw the alternating voltage of a transmitting device (T1) and the comparison alternating voltage (T2) with predetermined period duration from the alternating voltage sources (T34, T35, T36 and T37, T38, T39, respectively) in such a way that the two voltages remain in a constant relationship with one another with respect to their phase angle. However in comparison with the phase angle of another alternating voltage, the phase angle varies with the predetermined period duration. Using electronic load relays (G11, G12, G13 and G21, G22, G23, respectively) and voltage detectors (U1 to U6), a satisfactory, correctly sequenced switching of the load relays (G11, G12, G13 and G21, G22, G23, respectively) is ensured. <IMAGE>

Title: Circuit arrangement for increasing the operational reliability during the exchange of information between control devices of telecommunication, particularly telephone, switching systems
Inventor: WEISENBERGER FRANK DIPL ING
IPC: H04Q3/545
Filed: 1983-04-27
Abstract: The present circuit arrangement provides that a central control device is connected via at least two interfaces to the star point provided for the exchange of information. These interfaces are continuously in operation because they are alternately used in dependence on the address of the decentralised control device which has to be transmitting or receiving. In the case of a fault, the exchange of information is exclusively carried out via an undisturbed interface. It is furthermore provided that there are several central star points. In this arrangement, individual part-star points are formed which in each case have their own bus line for the exchange of information and have their own system bus control. Using majority decision logic arrangements, faults are found and in the event of a fault, the part-star point which is defective in each case, or parts thereof, are switched off.

Patent DE-3334522-A1 (DE)
Title: Sheet feeding device
Inventor: KAMEYAMA TOSHIAKI
IPC: B65H3/06
Filed: 1983-09-23
Abstract: A sheet feeding device has a drawing-off roller for feeding a sheet using the friction which is generated between the sheet and the drawing-off roller which rests under a certain amount of pressure on the sheet, a feeding roller for feeding the sheet and a separating roller which exerts pressure on the feeding roller at a contact point. The separating roller is driven in a direction opposite to the direction of rotation of the feeding roller, but it rotates in the same direction as the feeding roller, and together with it, once a load exerted on the separating roller has exceeded a predetermined value, so that the feeding of two sheets, with one covering the other, can be avoided. The pressure exerted by the pressing roller on the sheet is increased by a pressure exerting device when a sheet feeding action is started, and the pressure exerted on the drawing-off roller by the pressure exerting device is removed once the front end of the sheet has at least been taken over between the feeding and the separating roller.
