Patent DE-4203175-A1 (DE)
Title: Channel selection circuit esp. for telecommunication satellite - has ring of switches interconnected with bridging by one out of every three four-position rotary switches
Inventor: SCHUFF HERBERT DIPL ING
IPC: H04B1/74
Filed: 1992-02-05
Abstract: The circuit establishes k connections free from branching and combination between m inputs and n outputs with four-position waveguide switches arranged in a ring, every third switch serving as a bridge.

Title: Reel transport - has a bar to doff heavy reels which has an end catch to prevent the reel slipping off the bar
Inventor: ADENHEUER FRANK
IPC: B65H67/06
Filed: 1992-11-26
Abstract: A transporter bar for reels is loaded in one direction, and the free end of the bar has a barrier to prevent reels sliding off in the other direction. The bar (10) has suitable support for doffing the full reels of yarn or tap (20,22,24,26). A catch (32) has a lever (28) with spring (34) attached and hinged at (30) inside the end of the bar. By means of a rod or cable (36), and the attachment (38) at the control point, it is possible to remotely control the end of the bar, so that none of the reels can slip off the end. It is also proposed that the catch should be operated electromagnetically, with a cable connection to control it. Alternatively, by use of compressed air, the catch can be forcibly operated. This may be remotely operated with cable connection to a hook style lever which protrudes from the end of the bar (10), thus forming an end catch which prevents the reel slipping off, once in position. The catch retracts during loading. ADVANTAGE - The mechanism prevents any reel from being dropped off the bar and damaged, which may then be unusable.

Patent DE-4334911-A1 (DE)
Title: Method and device for peeling cooked vegetables or fruits
Inventor: SEIFERT FRANK
IPC: A23N7/02
Filed: 1993-10-13
Abstract: The consistency of the cooked product is critical above all. Even slightly exceeding the permissible forces leads to destruction of the product and to soiling of the operating elements. It is therefore the object of the invention to develop a method and a device of high productivity for peeling cooked vegetables or fruit, in which method the goods to be prepared are not destroyed, the degree of soiling is significantly reduced and the cleaning of the operating elements is easily possible. This object is achieved in that the goods to be processed have in each case simultaneous contact at least at three different points with a delivery element and in that the delivery elements are operated at speeds which differ from one another, so that shear stresses occur in the outer layer of the goods to be processed and a relative movement occurs between the peel and the body, which leads to separation of the peel. Peeling of cooked vegetables or fruit, in particular boiled potatoes.   <IMAGE>
Patent DE-4339099-A1 (DE)
Title: Speed regulation and torque control of electrical machine for vehicle testing
Inventor: BENDEL REINHOLD DIPL ING
IPC: H02P7/28
Filed: 1993-11-16
Abstract: The procedure involves setting the current of the electrical machine so that it creates a shaft moment, via the air gap moment of the machine, which corresponds to the required positive or negative limiting moment of an overlaid speed control, or the target moment of the selective torque control. A switch (6) selects as input either a value calculated from the target speed and existing speed of the machine (12), or the output of a circuit which generates a target torque. The output of the switch (6) is processed by an adder (3.2) and a torque calculator (10). This takes into account the frictional losses of the machine and its flux to generate the appropriate armature current in the machine (12) via a divider (7) and a current regulator (11).
