Title: Monitor for electrical systems, esp. in motor vehicle - operates for low supply voltage using led for failure indication
Inventor: MAUSNER EBERHARD DIPL ING
IPC: F01M5/00
Filed: 1980-11-18
Abstract: A device produces an optical signal when a deviation occurs from a predefined designed voltage level. The use of a liq. crystal display means than an error signal can always be given when the supply voltage is low, since the signal requires hardly any voltage. The liq. crystal display (14) is the monitoring device and is held in a first state as long as the demanded voltage value is maintained. When the voltage level deviates from the demanded level the display control signal is set to null and the display held in a second, inactive state which indicates the presence of a fault in the monitored facility (11), e.g. oil pressure.

Inventor: ZOOR REINHOLD
IPC: A63C9/02
Filed: 1981-03-02
Abstract: A ski binding includes a retainer for confining and supporting a ski boot. The retainer is pivotally mounted on a ski via a pivot located near the front of the binding. The retainer has a plate which is positioned near the front of the binding and serves to support a ski boot. The plate has a recess which accommodates a pair of springs. One end of each spring bears against a wall of the recess while the other end of each spring bears against a rod which extends into the recess. The end of the rod which is located outside of the recess is secured to a pivot which is located above or below the pivot for the retainer. The arrangement is such that the springs are stressed in tension or compression as the retainer is pivoted away from the ski thereby exerting a restoring moment on the retainer. The arrangement makes it possible to maintain the restoring moment essentially constant over the angular range which occurs during use. The springs are preferably stressed in compression in order to obtain increased life.

Title: Contact system for gas-blast power circuit breakers
Inventor: HESS RUEDIGER DR RER NAT
IPC: H01H33/915
Filed: 1981-08-25
Abstract: In the case of a contact system for gas-blast power circuit breakers having two stationary contact elements (1, 2) which are arranged on one axis, said stationary contact elements (1, 2) are connected in the switched-on position by means of a moving bridging switching element (3). The bridging switching element (3) consists of a multiplicity of spring-loaded contact fingers (4) which are arranged in an annular shape and continuously rest against a contact element (2) (guide contact element). The bridging switching element (3) furthermore consists of a sleeve (6) which surrounds these contact fingers and is electrically conductively connected, on its side (3a) facing the other contact element (1) (interrupter contact element) to an arcing ring (7) which is mounted in front of the contact fingers (4). In order to increase the life of the contact fingers (4) in that the contact fingers (4) are removed from the effects of the arc in the region of the interruption path (T), the invention consists of the contact fingers (4) being electrically insulated from the sleeve (6) and being capable of being moved (in the course of the switching-on movement) into an insulating region (14) of the guide contact elements (2) before the bridging switching element has separated from the interruption contact element (1), in that, under load, an arc is struck with a burning voltage which exceeds the ignition voltage between the interrupter contact element (1) and the arcing ring (7). <IMAGE>

Title: Method and apparatus for the horizontal continuous casting of metals, especially steel
Inventor: KUBON ACHIM ING GRAD
IPC: B22D11/10
Filed: 1981-09-18
Abstract: In a method of this kind for the horizontal continuous casting of metals, especially steel, the molten metal for casting flows into an uncooled storage container (1) and from there through a restriction (10) into a cooled horizontal continuous casting mould (3), and the cast strand (4), which has a solidified region (11) in the form of an annular crust, is pulled intermittently out of the horizontal mould (3). In order to avoid the unclean, non-uniform and cracked surface which arises when the cast strand is withdrawn continuously from the horizontal mould and, in particular, to improve the inadequate welding of the successively formed shells which occurs upon the backward jerk of the cast strand, leading to surface cracks, and in order moreover to increase the output of continuously cast material, it is proposed that, in addition to the intermittent withdrawal movements of the cast strand (4), shock-like pulses in the strand withdrawal direction be transmitted to the molten metal (1a) in the storage container (1) and/or to the molten metal (1a) or molten core (4a) within the horizontal mould (3). Apparatuses of two different designs are proposed for carrying out the method. <IMAGE>

Patent DE-3142272-A1 (DE)
Inventor: KROENER KLAUS
IPC: H04N5/06
Filed: 1981-10-24
Abstract: In magnetic video-tape equipment of the helical-scan type the vertical synchronizing information is situated at the beginning of a track near the edge of the magnetic tape. When the edge portion of the magnetic tape does not cooperate correctly with the head in the case of a faulty magnetic tape or apparatus, the vertical synchronizing information is not scanned and the resulting picture will roll in a vertical direction. However, since the beginning of a track coincides with the edges of the head-change signal, the vertical synchronizing information, in accordance with the invention, is always derived from the head-change signal, i.e. even during normal undisturbed operation, and is added to the CVBS signal, the signal scanned from the magnetic tape being blocked during this time. For this purpose the edge of the head-change signal is delayed and this delay is controlled so that normally the generation of the vertical synchronizing information from the line-pulse signals which are synchronized with the preceding track starts halfway between two such line-pulse signals or their active edges. Also when the permissible phase shift to the head change signal relative to the line-pulse signal upon each head change is taken into account the vertical synchronizing information always starts an equal number of half-line periods after the beginning of a track, thereby precluding a vertical picture jump, not even by half a line period.
