IPC: H01H31/00
Filed: 1990-04-19
Abstract: 2.1 Load interruptor switch installations are used virtually universally in medium-voltage distribution networks. In this case, compressed-gas-insulated installations are preferred. However, because of complicated busbar arrangements, it is not possible to house such switch installations in a very small space. 2.2 In order to achieve this object, it is proposed that a plurality of load interruptor switches be arranged in a gas tank (1) such that the switching blade (2) of one phase of the "on" position makes contact with a common contact piece (3) which is constructed functionally as a busbar. In this case, the contact piece (3) is equipped with extinguishing devices (6) for the switching blade (2). Furthermore, the earthing devices are constructed as earthing contacts (7) connected to a switch shaft (8). 2.3 Such switch installations can preferably be used in compact network stations in a very small space. <IMAGE>
Patent DE-4013980-A1 (DE)
Inventor: BODE BERTHOLD
IPC: G01N11/16
Filed: 1990-05-01
Abstract: A device is disclosed for measuring the viscosity of fluids by means of a measurement sensor (3) having a cylindrical piezoelectric base body (2) with four electrodes (5, 5<1>, 6, 6<1>) mutually separated by the same angular distance and arranged on the cylinder envelope in a direction parallel to the cylinder axis. The measurement sensor (3) is retained in a holding device (34) and is linked to an alternative voltage source, the voltage of which is supplied to the electrodes of the measurement sensor in order to generate torsional oscillations. An evaluating unit detects the electric reaction of the measurement sensor to the applied alternative voltage and deduces therefrom a characteristic value to determine the viscosity of the fluid that surrounds the measurement sensor. On each front face of the cylindrical base body (2) of the measurement sensor are arranged two mutually opposite electrodes interconnected by a metal film (7, 8) applied on the front face. A metallic holding element (9, 10) that projects axially outwards is embedded in each front face of the piezoelectric base body. An electrically conductive connection between the metallic holding element (9, 10) and the metal film (7, 8) is ensured by a layer that contains a metal and that is baked at a higher temperature in the connecting zone between the holding element and the metal film.

Title: Synthetic yarn false twister appts. - passes untwisted yarn through a heating stage directly followed by false twisting and cooling
Inventor: MARTON ERICH ARPAD
IPC: D02G1/20
Filed: 1990-08-16
Abstract: The appts. to apply a false twist, for texturising yarns of synthetic and other thermoplastic materials, has a heater where the yarn passes through without a twist.

The yarn is fed into the machine where it passes one or more times round a heated roller assembly, to be brought to the required temp.. The yarn can be drawn between the initial feed and heating. On leaving the heated rollers, the yarn is false twisted to be taken out and wound.

Patent DE-4110411-A1 (DE)
Inventor: KEMPE ACHIM DIPL ING
IPC: H01H47/08
Filed: 1991-03-29
Abstract: The heavy requirements made of hinged-armature relays for use in motor vehicles, which have to provide increasingly heavier switching powers with high inductive loads, more compact construction and lower losses, can no longer be met with the desired reliability  and operational safety by conventional hinged-armature relays. Even the contact gap can no longer be perceptibly increased although such is decisive for switching high inductive loads. These problems are avoided by arranging two coil windings (10, 11) wound and with current flowing through them in the same direction but  with different dimensions as the attraction (10) and holding (11) windings in parallel, and fitting a time-delayed electronic switch-off for the attraction winding (10) when the hinged armature (4) has reached the attracted position. A transistor stage with delayed switch-off may be used for this. In addition, the switching contacts (5, 6) are actuated via a special switch lever system so that the contact gap is considerably increased for the same installation dimensions.
