Patent DE-4302788-A1 (DE)
Inventor: WALCZAK BRUNO
IPC: B21C1/30
Filed: 1993-02-02
Abstract: The invention is concerned with the translational movement of components (21) with the aid of an enclosed cam (40), arranged on a peripheral cam carrier (33), for mechanically carrying along the components which are to be moved backwards and forwards by means of the cam in a working direction and a return stroke direction, the said components being carried along by means of drivers (34) which rest on cam faces and preferably have rollers (26, 27) or drums as components which interact with the cam, at least one of the components resting on a cam face which is to be movable under force. It is proposed that the contact force exerted by the components be changed during one cycle of the cam in such a way that in the region of the reversal points (UT, OT) the contact force of at least the component which transmits the respective direction of movement is increased to such an extent that it corresponds at least to the mass force resulting from the braking and accelerating of the part to be moved, the component being held in contact with the cam faces with a minimum force outside the area of the reversal points. <IMAGE>

Title: Freewheeling diode for a GTO thyristor
Inventor: BRUNNER HEINRICH DR
IPC: H01L29/861
Filed: 1993-02-18
Abstract: In freewheeling diodes loaded with direct voltage which are connected in antiparallel with GTO thyristors in static converters, spontaneous failures due to loss of the blocking capability occur even when the diodes are operated distinctly below the rated blocking voltage. These failures, which are presumably attributable to cosmic radiation, can be reduced considerably when the doping and the thickness of the centre zone are selected in such a manner that when the maximum blocking capability is reached, the field strength at the nn<+> junction is at least 0.2-times the field strength at the pn junction. <IMAGE>

Title: Device for controlling blades of vertical-axis rotors
Inventor: JUERGENS DIRK DIPL ING
IPC: F03D3/06
Filed: 1993-02-24
Abstract: The devices presently used to control the blades of vertical-axis rotors have a mechanical basis and are connected to the main drive of the rotor. They do not permit flexible adaptation of the setting angle to changed flow conditions. The novel device can change the setting angle characteristic in a variable way. The device for controlling the blades of vertical-axis rotors consists of a separate drive (1) which can change the setting angle of the rotor blades (3) via an appropriate mechanism (2). In order to generate a setting angle characteristic in accordance with the hydrodynamic (fluidic, flow-technical) requirement, the drive is connected to an electronic controlling system (5). The device for controlling the blades of vertical-axis rotors can be used for cycloidal propellers (Voith-Schneider propellers) and paddles of watercraft (vessels), as well as for wind wheels and water turbines with a vertical axis. Representation of the control system attached to the rotor for a rotor blade on the basis of a linear motor. <IMAGE>

Title: Fabric for the production of airbags
Inventor: KRUMMHEUER WOLF DR
IPC: D03D1/02
Filed: 1993-03-19
Abstract: For the production of fabrics for airbags, it is proposed to use synthetic hollow-fibre filament yarns with a hollow-area fraction of 10-40% in relation to the total cross-sectional area of the fibre. The use of hollow fibres makes it possible not only to reduce the production costs, but also to produce lighter fabrics.
