Title: Device for transformers and inductors, connected to a voltage, for measuring the clamping force for windings
Inventor: MATTHES WOLFGANG DR ING
IPC: G01L1/22
Filed: 1985-10-16
Abstract: This clamping force is frequently taken by tension elements which bear against core limbs (3), for example by tensioning cover plates (11) or by tie-rods, and transferred to the windings (5). In order to measure the clamping force, use is made according to the invention of strain sensors (17) mounted in the tensioning direction on a tension element (11) on both sides of at least one core limb (3) and of strain sensors (18) mounted at right angles thereto. In each case the four strain sensors (17, 18) mounted on the tension elements (11) of the same core limb (3) are electrically interconnected to form a quadrilateral bridge circuit. Measuring leads (19) connected to the corner points of the quadrilateral bridge circuit are led out in an electrically and magnetically screened (20) fashion from a tank surrounding the core (3) and the windings (5). The device according to the invention is chiefly suitable for use in generator transformers and line transformers and guarantees timely detection of a readjustment of the clamping force for the windings possibly rendered necessary following a series of short circuits. <IMAGE>

Title: UNIMOT electrical two-motor drive having a hybrid reversible-pole drum winding
Inventor: VARGA JOZEF DIPL ING DR
IPC: H02K16/04
Filed: 1986-06-03
Abstract: The invention relates to a drive solution for fully automatic washing machines having a high rotation speed in the spinning process. The "UNIMOT" drive combines a capacitor/induction motor for the washing mode, having a relatively high number of pairs of poles, and a universal commutator motor, having a small number of pairs of poles, for the spinning mode in only one stator and rotor core. The stator contains a multistrand winding which is normal in the case of single-phase capacitor motors and has a high number of poles (2 P1 > 2), and a single-strand, two-pole (2 P2 = 2) winding. Located in the rotor slots is a hybrid, reversible-pole drum winding having P1/P2 pairs of poles. This winding acts on the one hand on the stator field having P1 pairs of poles, in a similar manner to a multiphase squirrel-cage rotor winding, and secondly acts on the stator field having P2 pairs of poles, like a normal drum lap winding. The novel feature in comparison with "SIMODOM" from Siemens is the new and cheap, complete rotor design.

Title: Transformation element for converting the field width of the fundamental mode of single-mode optical fibres
Inventor: NEUMANN ERNST-GEORG PROF DR
IPC: G02B6/26
Filed: 1986-06-21
Abstract: The invention relates to a transformation element for converting the field width of the fundamental mode of single-mode optical fibres, which is constructed as a short, optically conductive element which is homogeneous in the direction of radiation and whose index of refraction in the core region deviates from that in the surrounding cladding region. The solution succeeds due to the fact that the refractive indeces in the core region and in the cladding region have essentially uniform characteristics in the radial direction and change in a stepwise fashion upon transition from the core region to the cladding region, and that the axial length of the transformation element is smaller than 15 times its thickness or its diameter. <IMAGE>

Title: Flame-resistant, halogen-free resin filling mixture as fire protection medium
Inventor: KRESTEL WILHELM ANDREAS DIPL C
IPC: C09K21/14
Filed: 1986-11-06
Abstract: The invention describes a flame-resistant, halogen-free plastic filling mixture as fire protection medium in the form of sheets, tapes or profiles, where the mixture contains a polymer which is substantially gas-impermeable when exposed to heat (5-10% by weight), fillers (70-85% by weight) and a plasticizer (10-20% by weight), which mixture, on contact with flames or heat (750-1050@C), tends to form a crust, by the KRECROSS effect. In the patent claims, the flame-resistant resin filling mixture is surrounded by a glass silk fabric tape which has been surface-treated, preferably on one side, with metal oxyhydrates. Tucks divide the glass silk fabric tape bag produced into chambers. The time delay of energy (break-through of heat at the level of 900@C on one side to 140@C on the other side) is greatly reduced via the mat thickness and/or the number via the KRECROSS effect.
