The frequency of the excitation source (11) is higher than that of the primary supply to the rectifier (3) of the converter (1) providing motor power. The excitation transformer winding (10b) has a higher number of poles than the damping winding (13a,13b), but is wound in the same slots. Pref. the windings lie side by side near the slot opening. By short chording the winding with the low oole number the actual coil span of both damper and transformer windings can be made equal. The use of three-phase excitation gives better utilisation of active material in the machine. A typical application for the motor is in electric traction for railways.

Patent DE-3003958-A1 (DE)
Title: Compensation of radioactive radiation sinks - by covering soil with radioactive material of suitable intensity
Inventor: KLEIN GERALD DIPL ING
IPC: G21H5/00
Filed: 1980-02-04
Abstract: Radioactive radiation which is emitted from rocks and soil is not uniformly distributed but depends on the type of rock and on the screening by underground water or geological faults. This weekened radiation can be balanced by burying in the ground radioactive material in sand, gravel, paper or textile material which have been sprayed. Plants which can absorb radioactive substances can also be used in these sinks. It is thought that the deficit of radioactive radiation leads to illness and indisposition for some persons. The suggested procedure eliminates these possible causes.

Title: Semiconductor impurities gettering - by interference producing element in ray path from pulsed laser
Inventor: KRIMMEL EBERHARD DR
IPC: H01L21/268
Filed: 1980-05-07
Abstract: A device for gettering impurities in semiconductor crystal wafers, pref. from the rear of the wafer, includes a radiation source which produces energy pulses and is arranged in axial alignment to a wafer holder. An element, introduced in the path of the rays between them, produces on the semiconductor crystal wafer fine interference figures in the order of magnitude of the applied wavelength. A radiation source (1) is pref. a giant pulse laser with an emission duration in the nanosecond area. It can be a gas laser on the basis of helium, neon, argon, CO2, iodine or eximer, or a solid laser based on ruby or Nd-YAG. The interference producing element can be a biprism, an optical parallel reticle or a transparent plate (3), lined with glass beads (4) of a greater diameter than the wavelength of the light used, e.g. 5 mu. This produces light sources, capable of generating interference lines on the semiconductor wafer (6) on the holder (5). Using for silicon an energy density of 10 Joule per sq.cm. and a pulse duration of 20 n sec, produces a getter layer of 1-2 mu. This creates a simple and fast method for the gettering of impurities which is compatible with the mfg. process stages.

Title: Shield driven tunnel tube site concrete lining - has reinforcement under shield tail protection and offset outer concrete shell
IPC: E21D9/06
Filed: 1980-06-20
Abstract: The advantages of monolithic and sectioned assembly methods are combined in a process for constructing cladding made of site concrete for a tunnel tube opened up by shield forward driving. Reinforcement (5) is introduced into the site concrete cladding already prepared, within the protection of the shield tail. The transposable inner formwork is then mounted and filled with concrete. Concrete for an additional, outer concrete shell (4) is then applied, offset from this in time and space, between the inner shell and rock, while the shield is travelling. This makes it possible to provide both reinforcement and a sealed finish.
