Title: Ball-type transformer
Inventor: DUERING JUERGEN
IPC: H01F30/08
Filed: 1987-02-06
Abstract: A large amount of heat is released in the iron core of conventional transformers. Instead of this, I wind two wires like a ball and omit the iron core. In accordance with Coulomb's law, the first wire produces an opposing electrical field in the second wire. The wires are located physically with respect to one another such that their cross-section produces a pattern like a chessboard; black being the one wire, and white the other. I can produce different voltages by connecting individual turns of the one wire in parallel instead of in series.

Title: Method and device for measuring an angular offset
Inventor: GENTER JOACHIM
IPC: G01R31/34
Filed: 1988-03-17
Abstract: The present method and the device which operates in accordance with it relate to the determination of the angular offset of commutators and armatures of the rotor of electric motors which are arranged in a rotationally fixed fashion on the same shaft. The angular offset is expressed as that of the longitudinally extending slots arranged in the lateral surfaces of the commutator and armature. Such an angular offset severely impairs the output of the relevant electric motor and should therefore be more rationally tested as early as during mass production of the rotors. This testing has previously been conducted mechanically by pressing in of test mandrils, test feelers or the like, and this has been correspondingly time consuming and yet inaccurate. In the present case, the rotor is inserted in the device and driven, and preferably optical or other contactless sensors arranged at right angles to the rotor are used to record the instant when the slots of the commutator and armature pass and to compare them with one another. From this, a connected computing unit determines the average as well as the maximum and minimum, optionally absolute or also relative angular offset of the slots of the commutator and armature, and indicates them.

Patent DE-3810991-A1 (DE)
Title: Sectional sign having a fastening plate
IPC: G09F7/18
Filed: 1988-03-31
Abstract: A sectional sign is known in which a support plate 2 and a fastening plate 1 are joined and provided with a passage hole 10 for a fastening screw 22 to be plugged through. It is in this case desirable if the fastening screw is provided, in a simplified way in terms of assembly, in an area of the support plate which is remote from the reinforced edge area of the support plate, while the support plate and fastening plate support each other. This is achieved in that the passage hole 10 of the support plate 2 is provided in an area of the support plate which, due to a dome 19, is at a distance from the fastening plate 1, in that a distance bush 24, which is penetrated by the fastening screw 22, can be inserted between the area surrounding the passage hole 10 of the support plate 2 and the area of the fastening plate 1 provided with the dome 19, and in that the distance bush 24 is formed in an opening 25 of a transverse web 27 and is connected to the remainder of the transverse web 7 via tear-off (pull-off) bridges 26. Despite the dome and because of the distance bush a hollow space is avoided between the support plate and fastening plate so that neither of the two plates can bend through when the fastening screw is tightened. <IMAGE>
