Title: Method and device for the isolated measurement of direct current and alternating current
Inventor: FIEBIG ARNIM
IPC: G01R19/22
Filed: 1987-04-08
Abstract: A method for the isolated measurement of direct current and alternating current with the aid of a toroidal core exhibiting at least two windings, through a first winding of which the current to be measured flows, is proposed which is characterised in that a magnetising current changing about a zero point is conducted through a second winding, the toroidal core being saturated both with the positive and with the negative magnetising current, and in that the value of the magnetising current is detected for determining the current to be measured. The magnetising current is generated by a squarewave voltage present at the second winding and is sampled in each case immediately after the change in polarity of the squarewave voltage before the toroidal core reaches saturation, and the current to be measured is determined in this fashion. <IMAGE>

The latter seal should be of simple construction, producible at low cost and have a long life expectancy. According to the invention, the carrier ring (1) is provided with a plurality of recesses (3) in which projections (4) on the sealing lip (2) are arranged. The sealing ring according to the invention can be used with particular advantage particularly in circular self-cleaning (spike) harrows. <IMAGE>
Patent DE-3812097-A1 (DE)
Title: Electrical plug connector coupling
Inventor: HESS ANTON-JOSEF
IPC: H01R13/629
Filed: 1988-04-12
Abstract: An electrical plug connector coupling is proposed which, inter alia, consists of a first plug connector part and a second plug connector part as well as a slide which is held on the first plug connector part such that it can be displaced at right angles to the insertion and withdrawal direction of the plug contact parts. The two plug connector parts are separated and joined together by a displacement movement of the slide between two limit positions. To this end, the slide is held by means of its base, which is constructed as an operating element, along the head side (facing away from the second plug connector part) of the first plug connector part such that it can be displaced essentially parallel thereto, the two limbs of the slide partially engaging around the longitudinal sides of the first plug connector part, originating from the base. This ensures that the slide does not project beyond the ends of the plug connector coupling in either of the limit positions of the slide, and that the overall space requirement for the plug connector coupling is increased only insignificantly by the slide.

Title: Transfer gearbox arrangement in motor vehicles
Inventor: MARTIN HARRY
IPC: B60K17/346
Filed: 1988-05-25
Abstract: A transfer gearbox arrangement (1) in four-wheel drive motor vehicles for variable torque distribution and lockable differential action is described. For this purpose two planetary gear trains (6, 4) are provided with different torque transmission. The internal gears (11, 12) assigned are each connected to an output-side primary shaft (15) by way of a hydraulically shiftable and pressure-controlled friction clutch (13, 14). The torque distribution and the locking action for the primary shaft (15) and a secondary shaft (10) can thereby be steplessly adjusted over a wide range. In addition, a one-way clutch (16) is situated in a parallel drive connection to the friction clutch (13). In this way, engagement of the friction clutches (13, 14) is changed smoothly. For controlling the friction clutches (13, 14), vehicle signals are used, which indicate the traction and the driving stability. <IMAGE>

IPC: H04Q9/14
Filed: 1988-08-08
Abstract: In known systems of the aforementioned type, the individual elements are in each case very highly adapted to their intended application and therefore offer little flexibility in use. This results in high development and production costs. The new signal transmission device is intended to be more flexible to use and cheaper to develop and manufacture. The new system is characterised by a main transceiver module designed as a separate master module (1) and a plurality of secondary transceiver modules in each case designed as slave modules (2, 3, 4), the modules (1, 2, 3, 4) in each case containing all the components required for two-way transmission and reception of addresses, commands and signals and their serial/parallel and parallel/serial conversion. The modules (1, 2, 3, 4) represent standard elements which can be used in a versatile and flexible manner and which communicate with one another via a bus line, preferably comprising four wires only. The master module (1) and a central control unit (100) or each slave module (2, 3, 4) and at least one setting and/or signalling component (200, 300, 400) communicate with one another via standard interfaces. The new telecontrol and/or telecommunications system is suitable, for example, for alarm and monitoring systems, heating and air conditioning system controllers or fire alarm and extinguisher systems and similar applications. <IMAGE>
