Abstract: PCT No. PCT/DE88/00085 Sec. 371 Date Jul. 19, 1989 Sec. 102(e) Date Jul. 19, 1989 PCT Filed Feb. 18, 1988 PCT Pub. No. WO88/07257 PCT Pub. Date Sep. 22, 1988.A high-frequency transformer is proposed in which at least one elastic carrier (18, 20) is constructed with openings (22 to 29, 52, 69, 73, 74) and also with cutouts (30 to 33, 53, 70, 71, 75, 76, 77) in such a way that the regions on the carrier (18, 20) delimited by the cutouts form a tongue (72, 78), which may be lifted to insert a magnetic core (13 to 16). Around the cores (13 to 16) in the openings (22 to 29, 52, 69, 73, 74) conductor tracks (51, 57, 58, 80, 81, 92) are mounted on one or both sides of the carrier (18, 20), and are completed as a turn or as a continuous winding by conductor track parts (64, 66, 67) mounted on bridges (17, 19, 21). At definite locations, the conductor tracks (51, 57, 58, 80, 81) have bonding pads (85, 89, 91) for surface mounted devices (38 to 41, 86, 87). In common with the insulation spacings between the conductor tracks, the conductor track widths are adjusted to the dimensions of the surface mounted devices (86, 87). Because of the construction of alternating layers of carriers (18, 20) and bridges (17, 19, 21) it is possible to realize a pre-set number of coil turns. Consequently, with the high-frequency transformer it is possible to realize all electronic circuits, especially such as have high-quality repeating coils, up to a high operating frequency and with a high packaging density of the components.

Title: Field-effect induction apparatus using the magnetic semiconductor properties of superconductive materials for converting magnetic energy into electrical energy
Inventor: PRIEBE KLAUS-PETER DIPL ING
IPC: H01F6/00
Filed: 1987-03-19
Abstract: The field-effect induction apparatus uses the energy which is available in magnetic fields for conversion into electrical energy. The apparatus consists essentially of a given, largely homogeneous magnetic field, a screen, which is formed by superconductive materials, of induction coils which changes between states where it conducts magnetic fields and states where it screens magnetic fields, by the use of additional induction coils. In the event of suitable materials and suitable geometries for the individual components of the field-effect induction apparatus being selected, a positive energy balance can be represented with respect to the cooling outlay for superconductive materials which is still required and the excitation outlet on the one hand, and the induced electrical energy on the other hand.

Title: Short-circuit protection for current-source inverters
Inventor: SCHENKE GREGOR DR ING
IPC: G01R31/02
Filed: 1988-01-12
Abstract: Electrical equipment, particularly also in underground mining, must be protected against the effects of short circuit currents by means of short-circuit protection elements in accordance with VDE 0118/part 2/draft 1/82. This short-circuit protection cannot be achieved by using currently conventional short-circuit protection elements in current-source inverters. Together with commercially available voltage and current transformers, an electronic module which is installed into a plug-in housing is provided as short-circuit protection for current-source inverters. The electronic module consists of the respective adapter in accordance with the delta circuit, followed by a fast RMS-forming circuit for the voltages and currents and analog IC dividers for the determining the respective conductances. The currents and conductances are evaluated by means of comparators and processed further in the subsequent logic which then drives a relay. This relay switches a latching relay which can only be energised when the inverter is ready for operation. The latching relay indicates the short circuit and triggers the disconnection via the main contactor.

Title: Method and device for the germicidal treatment of free-flowing goods
Inventor: BOEHNENSIEKER FRANZ
IPC: A61L2/10
Filed: 1988-09-15
Abstract: In a method for the germicidal treatment of free-flowing goods the goods are exposed to the UV radiation of UV radiation sources (2) during movement along a transport path. Transport of the goods is effected on a support surface (1) which defines a slope along which turning elements (9) having a plough blade-like configuration are moved in a direction opposite to the flowing direction at a rate matched to the inclination of the support surface (1), so that the goods are transported along the support surface (1) opposite the flowing direction at a rate which is smaller than the rate of movement of the turning elements (9). The goods thus treated can then be conveyed further in layers in the flowing direction along conveying belts (10) lying on further slopes and at the same time exposed to the radiation of further UV radiation sources (11). The conveying belts (10) can be driven in a direction opposite to the flowing direction, and this results in successive thinning of the layer thickness of the goods present thereon. <IMAGE>
