Title: Arrangement for monitoring the completeness of trains
Inventor: FUENTE PEDRO DE LA DR ING
IPC: B61G7/14
Filed: 1981-03-28
Abstract: In an arrangement for monitoring the completeness of trains, in which a radiation emission is exchanged under the train between the two ends of the train, the intention is to eliminate the risk that, when additional wagons are coupled on, the part of the arrangement located at the end of the train remains at the old point and thus some wagons are carried along in an unsecured fashion. For this purpose, the aforesaid part (4) is coupled with a coupling device (2) into the coupling hook (1) of the last wagon. The coupling device (2) fills, with one part (3), the coupling hook (1) in such a way that a coupling can no longer be hooked into the said hook (1); when the coupling is hooked into the free hook of a subsequent wagon, the coupling part (7) forces the arrangement out of the hook (1). <IMAGE>

Patent DE-3138957-A1 (DE)
Title: Brake pressure control unit for a motor vehicle hydraulic or pneumatic brake system
Inventor: KEINER KARL ING GRAD
IPC: B60T8/28
Filed: 1981-09-30
Abstract: In the case of a brake pressure control valve (10) for a motor vehicle hydraulic or pneumatic brake system a pressure relief valve (74, 90), connected into the pressure medium line between brake master cylinder and the wheel brake cylinders of the rear axle, comprises a differential piston (70) and a first flexible element in the form of a control spring (56), which on the one hand acts on the differential piston in the opening direction of the valve and on the other hand is supported on a clamping piston (50), the cross-sectional area (A1) of which is greater than the sealed-off area (A2) of the smaller piston stage (72) of the differential piston (70). The clamping piston (50) can be acted upon by the master cylinder pressure against the spring force of the first flexible element, and the master cylinder pressure acting on the clamping piston is limited by a valve (40, 44) closing as a function of the vehicle deceleration. According to the invention a second flexible element (94) is provided which acts on the differential piston (70) in the closing direction of the pressure relief valve, its spring force being less than the spring force of the first flexible element. As a result the switching pressure of the pressure relief valve does not always exceed the closing pressure of the deceleration-dependent valve by the same amount, but in the event of an increase in the closing pressure the switching pressure of the pressure relief valve is increased by a greater amount. Consequently a very close approximation to the ideal brake pressure distribution for the particular load condition of a vehicle is achieved by simple means without the need for a mechanical actuation between the rear axle and the vehicle chassis. <IMAGE>

Patent DE-3205293-A1 (DE)
Title: Device for sealing the gaps between the stones of stone pitching
IPC: E02B3/12
Filed: 1982-02-15
Abstract: The invention relates to a device for sealing the gaps between the stones of stone pitching on slopes and beds of stretches of water with a setting or hardening binding agent, with a distributor head which sweeps over the sealing area and on which at least one discharge nozzle of a binding-agent feed line is arranged. So that the desired penetration of the binding agent into the gaps is not left to the random automatic inflow of binding agent applied to the stone pitching, the free end of the discharge nozzle is always to penetrate as deep as possible into the gaps and is to be held there during operation with the device. According to the invention, this is achieved in that a section of the discharge nozzle projecting towards the stone pitching is hung in a freely oscillating manner on the distributor head. The discharge nozzle held deep in the gaps can avoid stones protruding into the feed path and in the process, in the gap to be sealed, is passed around the stone lying as an obstacle in the feed path.

Title: Thermodynamic drive for a liquid-metal MHD generator
Inventor: BOESE FRIEDRICH-KARL DR RER NA
IPC: F01K25/06
Filed: 1982-05-14
Abstract: The present invention relates to a thermodynamic drive for a MHD generator in a liquid-metal circuit. The invention proposes an improvement to a driving-gas circuit which serves for the acceleration of the liquid metal in the MHD generator. This improvement permits the use of a noncondensable driving gas at high temperatures. For this purpose, it is proposed, after the separation of the liquid metal in a separator (5), to bond the driving gas with a carrier in an absorber (8). The bonded driving gas is transported by a pump (9) to an expeller (1) together with the carrier, where the bonding process is reversed by the supplying of heat. The expelled gas passes to a mixer (2) and then accelerates the liquid metal through an MHD channel (4). The carrier is passed back from the expeller (1) to the absorber (8) via a throttle valve (11). The energy system comprises three circuits: the liquid-metal circuit, the driving-gas circuit and the carrier circuit. The efficiency of the plant is increased by suitably arranged heat exchangers (6, 10, 12). <IMAGE>

Title: Screwdriver for the defined tightening of screws by means of a tool operated by auxiliary force
Inventor: NUSSBAUMER DIETMAR DIPL ING
IPC: B25B23/14
Filed: 1982-06-12
Abstract: Torque and rotary angle are measured in a screwdriving tool. Several "windows" through which in the normal case the torque/rotary angle characteristic has to pass are in each case predetermined by maximum and minimum torque and maximum and minimum rotary angle. A computer checks step by step whether the characteristic curve runs through all these windows. If the characteristic curve does not run through all the windows, the screwdriver is switched off and an error signal is transmitted. After the last step, the screwdriver is switched off and a check is made as to whether the characteristic curve ends in the last window after the after-running due to inertia. The behaviour of the characteristic curve is shown on a monitor.

Title: Wind-power machine
Inventor: GASAFI ANTON
IPC: F03D3/06
Filed: 1982-06-25
Abstract: The wind-power machine possesses a wind wheel (16) of vertical axis (18), on which vanes (27) are arranged pivotably about a vertical axis. The vanes (27) are so retained on the side of the wind wheel running with the wind that they present an engagement surface to the wind. However, they are suspended in such a way that they can set themselves into the wind on the side of the wind wheel running counter to the wind and therefore present no engagement surface to the wind.
