Title: Mobile spinning station maintenance unit - has sensor to register proximity of following unit to move on and prevent bunching
Inventor: HARTMANNSGRUBER MAX DIPL ING
IPC: D01H13/00
Filed: 1980-10-23
Abstract: Each mobile maintenance unit travelling round the assembly of spinning or twisting stations, such as to repair yarn breakages etc., is fitted with a sensor. On the approach of the second maintenance unit, registered by the sensor, the maintenance operation is suppressed for an interval at least as great as the next spinning station where a service need is detected. The sensors are located at the rear of each maintenance unit. The maintenance operation is suppressed by a number of following spinning stations identified as in need of service, calculated by the number of stations statistically needing attention on one circuit of a maintenance unit, and the number of maintenance units provided for the assembly. The counter in each unit is preset by the calculation, and a service need signal is carried from the monitor through the counter to the service operations unit if activated by the sensor, after which it is deactivated and the counter register erased. The mechanism ensures that a proper interval is maintained between the maintenance units, so that each can function irrespective of the operating speed of each unit.

Patent DE-3123493-A1 (DE)
Inventor: KNUETTEL BERTOLD DIPL PHYS
IPC: H01F7/20
Filed: 1981-06-13
Abstract: An electromagnet for producing the constant magnetic field required for use in NMR tomography consists of a cylindrical field coil and a stable cylindrical shell made of iron encompassing and simultaneously supporting the coil. The field coil may comprise constituent coils, including error coils, and is capable of producing an at least approximately homogeneous magnetic field within the space defined by the field coil for receiving the object to be examined. Due to the strictly symmetric geometry of the coil assembly, the homogeneity of the magnetic field is not adversely affected by temperature fluctuations, even if the dimensions of the apparatus are such that the coil will admit a human body. The cylindrical shell, however, does not only serve as an extremely stable supporting means, but also forms the vehicle for a magnetic reflux by which the energy requirements of the magnet are considerably reduced, and further, also constitutes shielding means both against external magnetic fields and electromagnetic interference and radiation from the high frequency field produced in NMR tomography. The cylindrical iron shell may be provided at its end portions with operational members such as annular discs and tubular studs and may be closed by iron covers, so that its effectiveness may even be further enhanced.

Title: Method and press for the reduction, in particular deep-drawing of workpieces composed of metal
IPC: B21D22/22
Filed: 1982-03-03
Abstract: The invention relates in general to metal forming and is directed, in particular, to a method and a device for the extremely high-percentage reduction of metal during a metal forming operation. The method comprises the insertion of a metal shape under pressure by the exertion of pressure on its peripheral edge faces and simultaneous engagement of the metal with a drawing punch. The device used to carry out the method contains a hold-down device and a drawing punch, which are carried by a movable spar of the press, and a die supported by the press foundation, the spar being movable towards and away from the foundation. The foundation furthermore supports an annular body or a matrix which supports a multiplicity of iris plates which are arranged in a circle around the centre axis of the drawing punch and can move towards and away from the centre axis of the drawing punch, allowing them to be brought into engagement with the peripheral edge faces of the shape when the press moves into the closed position and the drawing punch comes into engagement with the workpiece. In this way, the workpiece is put under radial compression simultaneously with the exertion of the forming pressure by the drawing punch and hence an extremely high-percentage reduction of the metal is achieved.

Patent DE-3213680-A1 (DE)
Title: Method and device for electrical heavy-current generation by activation and accumulation of an electricity plasma which is regenerated atomically from matter
IPC: H02K44/08
Filed: 1982-04-14
Abstract: Electrical heavy-current generation takes place by the efficiency-dependent use of heat and flow energy in prime movers for an electrical generator drive. Considerable outlay in terms of power economics is required for this purpose. An immeasurable power potential is available in matter. At absolute zero, matter is electrical plasma sublimated to form elementary solid particles. As a primary power generator, the atom is able to regenerate matter into energy-carrying electrical plasma. The magnetism force for impressing matter, from which that of atom nucleuses is derived, was powerful with respect to mass at zero Kelvin. The free elementary particles which circulate as electrons through the atom nucleus sink pole to the source pole determine the voltage potential by their rotation speed. During every nuclear magnetic passage, one electron mass quantum resublimates via the state form of magnetic plasma in a speed-conformal manner into energy-carrying electricity plasma. As a result of the electric field and/or the radiation influence, the electron speed is accelerated and the potential raised. The introduction of the nuclear magnetic force at the original state of zero Kelvin by means of cryogenic temperature insertion produces excitation with the same effect. In a large atom stack, that is to say numerable electron-rich, polarity-rectified metal conductor atoms, the individual lines are added. By connecting the power network return line to the large atom sink pole, the lower-voltage plasma current is technically prepared to supply the power network with voltage on the way to the source pole. Electron-rich metals of high atomic weight are preferably suitable as metal conductors as well as for potential excitation by large-atom external irradiation. The radioactivity of these materials is reduced by the cryogenic temperature, and their electrical resistance is reduced by superconductivity.
