Title: High-voltage switching chamber having an arc centring device
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/915
Filed: 1981-09-22
Abstract: The short-circuit current switching-off capability of a high-voltage autocompression compressed-gas switching chamber is intended to be increased by centring the switching-off arc in the axis space especially of stationary or movable double-nozzle arrangements. To this end, an arc centring device is proposed which is characterised essentially by the structural connection of the following components: a current conducting and/or gas outlet tube (7) and a tube (47) consisting of ferromagnetic material are connected without any spacing between the tube sections to form a double tube arrangement. A nozzle is inserted into the double tube arrangement. In the region of their ends facing the nozzle, the tube sections of the double tube arrangement are electrically conductively connected to one another. Outside this region, an insulating layer prevents current transfer between the tube sections. The insulating layer advantageously consists of potassium silicate or sodium silicate (water glass). The ferromagnetic tube is protected against arc erosion by an inserted tube consisting of erosion-resistant material. <IMAGE>

Title: Method for driving a digital display of traffic lights and arrangement for carrying out the method
Inventor: SAHORSCH JOSEF
IPC: G08G1/096
Filed: 1981-12-05
Abstract: In a method for driving a digital display of traffic lights, the light signal of the red lamp is received and used to resolve two counting operations, which alternate with the same clock frequency in opposite directions starting from the initial state zero in the forward direction or, starting from the final state reached during the preceding red light phase, in the reverse direction. The intermediate states of the reverse counting operation are continuously displayed on the digital display. The reverse counting operation is set to the initial state zero upon extinction of the red lamp at the latest, and the digital display is extinguished, while the forward counting operation is terminated upon extinction of the red lamp and the final state achieved is stored during the following green light phase. Furthermore, in order to increase traffic safety the light signal of the amber lamp is received and used to reset the instantaneously running counting down operation to the initial state zero and to extinguish the digital display.

Title: Seal arrangement
Inventor: DANNENFELD JUERGEN
IPC: F16K41/02
Filed: 1982-02-10
Abstract: The invention relates to a seal arrangement for a reciprocating rod, in particular a valve spindle, which is arranged in a bore of a fixing body and is surrounded by a sealing element. A seal arrangement of this kind is intended to seal off from the environment an interior space around which a medium flows, in particular an interior space of a valve, there being particular requirements nowadays with regard to low emission rates. This applies especially in the case of a gaseous medium with a high creeping ability, and hydrogen may be mentioned in particular. There is furthermore a requirement for a long life or long maintenance intervals. It is therefore proposed according to the invention that the sealing element, which is preferably composed of an elastomeric material, be allocated an adjustable seal which surrounds the rod. By readjusting the adjustable seal, it is possible to maintain low emission rates even over a long period without the necessity of expensive assembly work. <IMAGE>

Title: Closed energy system No. 1
Inventor: SCHOEPPLER KLAUS-WERNER
IPC: H02K53/00
Filed: 1982-06-03
Abstract: Closed energy system No. 1, apparatus having a function which is similar to perpetual motion. In this case, an electric motor and a current store or a plurality of motors with or without current stores are incorporated in an arrangement within which the motor is switched to generator operation in order to brake the rotational movement of the motor, whereupon its motion is braked and a current is produced. This current is stored and is reused for acceleration, or is just as well used for accelerating another motor. In order to clarify the effect resulting from this, and in order to extend the time duration over which the system works, the motors are located inside a vacuum, their moving parts being supported magnetically in order to overcome the frictional resistance. Current pick-offs on the motor must operate in a particularly low-friction manner, or without touching contact. The energy supply takes place non-recurrently. Since the energy is reused, the apparatus operates for a rather long time without any energy supply, specifically until the input energy has been lost to the system as a result of the small amount of conversion into heat etc.

Title: Method and device for measuring the surface temperature of moving objects, in particular for the intermediate monitoring of the temperature of filamentary products, preferably wires
Inventor: KISS LASZLO DIPL ING
IPC: G01K13/06
Filed: 1982-10-12
Abstract: The invention relates to a method and device for measuring the surface temperature, which serve in particular for the intermediate monitoring of filamentary products, preferably wires, during production. They are suitable, in particular, for measuring the temperature of ribbons, fibres and objects moving at a speed of 0 to 65 m/s, and ensure the possibility of measurement independently of the material and of the surface quality. The essence of the method and the device is the use of two concentric sheath surfaces whose corresponding parts can be heated or if necessary cooled, in order to achieve an identical temperature value on the entire surface. The desired temperature value is identified with the temperature of the central region of the inner sheath. The method and the device can also be applied in the range of values, the measurement of the thermal radiation being complicated.
