Patent DE-3006207-A1 (DE)
Inventor: SPIRK FRANZ
IPC: H02K17/42
Filed: 1980-02-15
Abstract: The laminations of a laminated stator of a slowly running electrical machine having a high number of poles are composed of grain-oriented sheets, each of which has a preferential magnetic direction that extends substantially longitudinally along the teeth of that sheet. This permits the excitation current to be reduced, and, as a result, the air gap of the machine can be enlarged so that, on the whole, approximately the same excitation is required as for a laminated stator in which the laminations consist of normal, non-oriented sheets. As a result, the mechanical stability of the machine is increased. The invention is especially useful in asynchronous tube generators.

Title: Wiegand wire - with alternating ferro and paramagnetic lengths produced by direct current passage and cuffs
Inventor: WEIGL ANDREAS
IPC: H01F1/03
Filed: 1980-04-19
Abstract: A WIEGAND wire, made of 37% Fe, 52% Co and 11% V, produces in its ferromagnetic state in an alternating field the so-called Barkhausen jumps. For use as displacement pickups, the wire should have a sequence of ferromagnetic with paramagnetic zones which exhibit no such jumps. This is best achieved by heating the wire in the paramagnetic zones to a dark red heat by passing a current of high density through them. The ferromagnetic zones are kept cool by applying heat dissipating cuffs.
Patent DE-3018373-A1 (DE)
Title: Warping process - uses warping action to cold-draw quickly-spun filament yarns
Inventor: BOGUCKI-LAND BOGDAN DIPL ING
IPC: D02H5/02
Filed: 1980-05-14
Abstract: Drawn multifilament synthetic yarns are taken individually from their spools, as warps to be wound on a warping beam. All the warp yarns are subjected to a common draw tension before winding or during warping, to give them a final cold-drawn final structure. The final cold drawing imposes a 30 - 40% stretch, which can be effected in two or more phases, using the actual winding on the warp beam as the final stretching phase. There is a common yarn drive with at least two rollers for all the warps drawn from the creel. The yarn drive has a significantly slower speed than the following drive unit for all warps. A number of drive units can be in the warp yarns' path, with an increasing speed rate in successive units, with the warping stage giving the highest speed in the chain. The process reduces fabric costs, as quickly-spun filaments can be used with little prepn. as the warp yarns.

Title: Figured weft-knit stretch fabric - using uncovered elastomeric yarn supported alternately by two non-elastomeric yarns
Inventor: WILSON DAVID
IPC: D04B1/18
Filed: 1980-07-03
Abstract: A stretch fabric knitted from an uncovered elastomeric yarn and a non-elastomeric yarn which are fed together to the needles has a figured pattern produced by floating the non-elastomeric yarn on a base of the elastomeric yarn, which continues to knit without the non-elastomer. To support the elastomer in the figured regions, a second non-elastomeric yarn is knitted with the elastomer at least in these areas. The use of a separate support yarn in the figured regions allows the use of an uncovered, in place of a covered, elastomeric yarn, which reduces the raw material costs and gives a lighter fabric.

Title: Monitoring system for digital regenerators - avoids use of addresses by counting telemetry signals sent cyclically from regenerators
Inventor: BRAUN EWALD ING GRAD
IPC: H04B17/40
Filed: 1980-07-22
Abstract: A telemetry signal is sent via the same path as the digital signals but in a different frequency band. Monitoring is performed separately for each direction of transmission. Each regenerator, beginning with the first, sends a telemetry signal comprising several data blocks describing the state of the digital signals received at the regenerator concerned and the functioning of that regenerator. The receipt of the telemetry signal from one regenerator initiates the transmission of the telemetry signal from the next regenerator. At the receiver the regenerators are identified by counting the telemetry signals. The data contained in the telemetry signals are evaluated at the receiver. Each regenerator has its own built-in monitor, which monitors its functioning during the transmission of one or more data blocks. These results are then transmitted in at least one following data block. The telemetry signals consist of a start block, an error block for monitoring the section of transmission line and the regenerators, a test block for the built-in monitoring of the regenerators and their test circuits, and at least one end block.
