Patent DE-4208164-A1 (DE)
Inventor: ESTERL ROBERT
IPC: H01H51/22
Filed: 1992-03-13
Abstract: A relay has a static core arranged inside the coil (12), and a swivelling armature arranged at one end of the coil that forms, together with two pole shoes (31, 32) at the other end of the coil, working air gaps with respect to one end of the core. The armature has two pole plate sections (31a, 32a) arranged in the extension of both pole shoes in a common plane outside of the coil and parallel to the axis of the coil, where they are coupled to one side of a four-pole permanent magnet. Both opposite poles of the permanent magnet are coupled to a flux plate which in turn forms a feedback to the core. With this system a polarized relay is obtained whose magnetic cross-sections can be very easily optimized and whose switching characteristic can be easily adjusted by balancing the permanent magnet. In addition, it is possible to easily separate the magnetic system from contact systems by means of appropriate insulating walls.

When the sun is high the rays may be reflected at a near horizontal angle into the room. ADVANTAGE - Makes a more effective use of natural daylight.
Patent DE-4214949-A1 (DE)
Inventor: REIME GERD
IPC: H03K5/12
Filed: 1992-05-06
Abstract: Two edge detectors (12, 13) at the input (10.1) and at the output (10.2) of a delay line (10) of the edge detector arrangement (11) generate detection signals with identical shape at the detected signal edges of a signal passing through the delay line. The delay time of the delay line is selected in such a manner that the two detection signals partially overlap in time. A subtracting arrangement (16) generates from the two detection signals a difference signal which contains in the overlap region a zero crossing which can be detected by a zero crossing detector (17). At the time of this zero crossing, the zero crossing detector generates the switching edge of an edge detection signal which, for example, controls a signal switch (9). <IMAGE>

Title: Method for exchanging information between control devices in a digital switching system
Inventor: MAIER KLAUS
IPC: H04L12/40
Filed: 1993-04-14
Abstract: The connection structure for exchanging information between control devices in a digital switching system is intended to remain constant irrespective of the number of switching systems or parts thereof. The transmission characteristics of the connection network are intended to remain unchanged if upgrades are carried out. Furthermore, uniform interfaces are intended to be used even when a plurality of system parts are interconnected. The control devices of all the components of one module are connected via uniform bus interfaces to a parallel bus running exclusively within one module. For the interconnection of a plurality of modules, a further parallel bus is provided which is designed in the same manner as the first parallel bus which is located within one module. The second parallel bus is connected via connection lines, which are in each case unidirectional and serially operated, to an associated first parallel bus. The uniform module structures and the selected transmission method allow a wide range of switching systems of different sizes to be covered. The principle of the arrangement remains applicable even when upgrades are carried out in a switching system.

Title: Tow bar support wheel for vehicle trailers in particular with a high body and caravan, with steering system, drive and free wheel
Inventor: STROBEL FRIEDRICH
IPC: B60D3/00
Filed: 1993-07-15
Abstract: Tow bar support wheels with steering systems offer considerable advantages in manoeuvring vehicle trailers with a high body or caravans in the uncoupled state. By virtue of the individual adjustability of the steering rod of the steering system according to the invention working positions can be assumed which permit the path to be travelled to be viewed even when the vehicle is being pushed backwards. Thanks to the provision of a drive acting on the steering rod on the wheel via a hand crank, even difficult paths can be travelled through with full manoeuvrability. In particular over long distances, e.g. in halls with narrow paths or densely occupied locations with small radii of curvature steerable tow bar support wheels with electric drive, supplied from a battery mounted on the device, offer further advantages since even gradients can be overcome effortlessly.
