Title: Rear wheel steering system for motor vehicles
Inventor: MATSCHINSKY WOLFGANG
IPC: B62D7/15
Filed: 1987-08-27
Abstract: A steering mechanism for the rear wheels of a motor vehicle is described which, when the front wheels are steered out of the straight-head position, initially permits, using simple means, the rear wheels to steer in the same direction, changing, as the front wheels are steered further into steering of the rear wheels in the opposite directions. For this purpose, a steering arm shaft (2) is provided parallel to the rotary shaft (1) and at a distance therefrom. A control link (7) is coupled to the free end of a radial steering arm (5) of the steering shaft (2) by means of a ball-and-socket joint (6). The control link (7) is connected via a first rotary joint (8) with rigid corners to an articulated axle (10) which extends transversely with respect to the axis (9) of the rotary shaft by one end of an intermediate lever (11). This intermediate lever (11) is connected at the other end to the steering arm shaft (2) via a further rotary joint (12) which is parallel to the first rotary joint. In the straight ahead position of the front wheels, the ball-and-socket joint (6) is located between the axes (9, 13) of the rotary shaft (1) and of the steering arm shaft (2). <IMAGE>

Title: Circuit arrangement for monitoring a low-resistance electrical component for interruption
Inventor: GRIESBAUM WILHELM DIPL ING
IPC: G01R31/02
Filed: 1987-11-04
Abstract: In automation systems, binary signal outputs, which are applied in great numbers, are protected by fuses in the output circuits. A circuit arrangement for determining blown fuses consists in that a potential-free test current source generates a test current, which flows through the fuse (SI) and an optocoupler (OK) connected in series with it. A reporting device is connected to the output of the optocoupler (OK). In the event of the blowing of a fuse, the secondary side of the optocoupler (OK) is blocked and the reporting device responds. The circuit arrangement works independent of whether a load current flows through the fuse. Main field of application of the invention is binary signal output modules of automation systems. <IMAGE>

Patent DE-3742319-A1 (DE)
IPC: B29D99/00
Filed: 1987-12-14
Abstract: A protective angle (1) made of a glass fibre woven mesh (2) connected to a plastic angle (3) is useful for reinforcing the corners and edges of external walls, in particular in connection with complete thermal insulation of buildings. The plastic angle has passages such that no continuous bridge extends along its whole length. For this purpose, a plurality of adjacent and offset equidistant slits arranged one behind the other are cut into a flexible plastic strip (6) using a cutter disk (7a). The plastic strip is stretched by means of a stretching device in such a way that the slits open to form passages. Next, the perforated plastic strip so obtained is folded by a shaping device (13) to form a profile cover strip angle (18, 3), and the perforated plastic angle is glued to a glass fibre woven mesh strip (2) to form a protective angle (1).

Patent DE-3811472-A1 (DE)
Inventor: MOEBIUS ANDREAS DR SC NAT
IPC: C25B11/03
Filed: 1988-04-06
Abstract: In a method of processing metal chlorine solutions by electrolysis, generation of chlorine at the anode is avoided, and the anode potential is reduced, by using as the anode a tungsten carbide-catalysed hydrogen diffusion electrode. The tungsten carbide-catalysed hydrogen diffusion electrode is preferably encased in a diaphragm in order to restrict the access of anodically formed hydrogen ions to the cathode. Metal chlorine solutions arising from the picking of metals with hydrochloric acid may be treated. The process may also be used to produce alloys or for the direct hydrometallurgical recovery of metal.

Patent DE-3837628-A1 (DE)
Inventor: BROESAMLE PETER DIPL ING
IPC: A01C3/00
Filed: 1988-11-05
Abstract: The invention relates to a process and apparatus for treating organic sludges, in particular liquid manure, with at least one electrode located in the liquid manure and at least one counter electrode, by applying a direct voltage source, a migration of ions in the liquid manure being excited by the use of any desired electrodes. The invention is based on the object of achieving a marked improvement in the homogeneity of the liquid manure within the shortest possible time at the end of intermediate storage periods inherent in the process. In process engineering terms, this object is achieved when a constant base voltage is built up and maintained in the liquid manure, superposed by a periodically interrupted overvoltage. In terms of apparatus, a basic appliance with a circuit for supplying the electrodes with base voltage and in addition a step transformer with rectifier are provided, which transformer is secured by current/voltage interlocks against controlling the base load and operates equidirectionally and whose overvoltage can be superposed upon the base voltage by means of an adjustable interrupter.
