Title: Video recorder with helical-track recording
Inventor: KLUTH HANS-JUERGEN ING GRAD
IPC: G11B15/473
Filed: 1981-04-18
Abstract: In a video recorder with helical-track recording, a synchronisation track is recorded along one tape edge. The invention provides for recording without this synchronisation track. The speed of the head wheel (1) is regulated from the vertical synchronisation pulses (14) scanned from the helical tracks (28). The necessary distinction between the odd-numbered and the even-numbered fields is obtained either by utilising the structure of the composite synchronisation signal (Figure 2), which differs from field to field, or by utilising the azimuth angle between the direction of the gap of the video head (2, 3) and the transverse direction of the helical tracks (28), which angle differs from helical track to helical track. <IMAGE>
Patent DE-3117147-A1 (DE)
Title: Road tunnel with forced ventilation
Inventor: FLEISCHER HORST
IPC: E21F1/00
Filed: 1981-04-30
Abstract: The invention relates to a road tunnel with forced ventilation, with an extraction duct (2) connected to a fan (3) and running along the tunnel. The extraction duct (2) is connected to the tunnel interior via a multiplicity of openings which are arranged one behind the other and can be opened and closed individually by servo-actuated flaps, shutters (louvres) or the like. A multiplicity of vehicle sensors (8, 8') arranged one behind the other is provided in the tunnel itself. Each time a vehicle (13, 13') coincides with one of them, the vehicle sensors (8, 8') transmit a signal so that each time one or more of the openings can be automatically opened towards the extraction duct and after a certain time can be automatically closed again. Thanks to this forced ventilation passing through the tunnel together with the vehicle, the equipment for this need only be designed for relatively light duty. Nonetheless, no special arrangements, for example track-guide measures or exhaust-gas snorkels, are to be made at the vehicles. The road tunnel of this type force-ventilated in an economical manner can readily be used not only by vehicles in public passenger service but also by taxis or ambulances. <IMAGE>

Title: Electrical switching device
Inventor: SCHOENEMANN OTTO
IPC: H01H13/703
Filed: 1981-07-24
Abstract: The invention relates to an electrical switching device, for example having a printed circuit board (1) and a switching element (6) which is arranged on a so-called switching mat (3) and which bridges conductor tracks (2) during its operation. A switching button (10) which can pivot and on which a switching piece (8) is supported such that it can pivot is used as the operating means for the switch. This switching piece engages over an attachment (5) on the switching mat (3) so that, when the switching button (10) is operated, the switching element (6) is moved parallel to itself with respect to the conductor tracks (2) of the circuit board (1). During the operation of the switch, in order to keep the relative movement between the switching piece (8) and the attachment (5) as small as possible, the plane of the pivoting axis (11) halves the switching movement (A) of the switching piece (8) from the quiescent position into the switching position. The switching button (10) can also be constructed as a switching rocker (12) so that it can optionally be operated on each side of the pivoting axis (11). The switching state of the downstream-connected devices can be indicated by a lamp (13). <IMAGE>

IPC: B60B33/02
Filed: 1981-09-12
Abstract: The castor according to the invention for movable objects such as rubbish containers or the like, is composed essentially of a connection plate, a rotary plate which is connected thereto in a manner such that it can rotate via rolling-contact bearings and supports the wheel fork as well as of an axially movable adjusting pin which penetrates through the centre of the connection plate and the rotary plate. This adjusting pin has locking means which are secured against rotation and can be brought by at least one of the components which are rotatable with respect to the connection plate into engagement blocking the rotatability of the wheel fork with respect to the connection plate. In order, on the one hand, with secure total blocking of the castor, to be able to arrange the locking means at a location facilitating installation and, on the other hand, to permit easy exchange, the locking means are formed by a locking star which is held non-rotatably on the adjusting pin and by a locking ring secured under the back of the wheel fork. When blocking is required, the locking star can be brought into positive engagement with the locking ring.
