Patent DE-3118353-A1 (DE)
Title: Thyristor having turn-off emitter short circuit
Inventor: PLATZOEDER KARL DR RER NAT
IPC: H01L29/745
Filed: 1981-05-08
Abstract: The thyristor is provided with a number of strip-type emitter zones (1a...1d) between which there are strip-type first electrodes (6, 7, 8, 9) which make contact to the base zone (2). Contact is made to the emitter zones by second electrodes (10...13). In order to switch on the short circuit, the first and second electrodes are interconnected by a field-effect transistor (14) whose source-drain section is situated directly between the said electrodes without the insertion of a voltage source. The thyristor can therefore be turned off by switching on the FET. <IMAGE>

Title: Process for joining thermoplastic materials and metals
Inventor: KAEUFER HELMUT PROF DR
IPC: F16B11/00
Filed: 1981-06-04
Abstract: The invention relates to a process for joining thermoplastic materials and metals by means of a self-hardening adhesive, the adhesive bonding taking place not only via an end abutment, but at the same time by means of a two-sided overlapping of the thermoplastic part around the metal counterpart. Preferably the groove is delimited by hook-shaped or U-shaped legs, the inner leg surfaces of which are inclined towards one another, so that a groove which tapers towards the groove opening is formed. In one embodiment, sealing elements are present on the inner wall parts of the hook-shaped legs which enclose the groove, which sealing elements are embedded in the adhesive on adhesive bonding. The groove or groove opening of the thermoplastic part contains sealing elements and/or forms them itself by means of one or more groove constrictions in the vicinity of the groove opening or between the groove centre and groove opening. The space formed from the groove base, sealing element and inner wall parts of the hook-shaped or U-shaped legs serves as a receptacle for an adhesive or an adhesive component.

Patent DE-3133238-A1 (DE)
Title: Compression cuff for haemostasis
Inventor: DUFNER HELMUT
IPC: A61B17/132
Filed: 1981-08-22
Abstract: Place the compression cuff on to the haemorrhage site (see figure). Then, to seal the haemorrhage, place the perforated strap around the arm, for example, and insert the corresponding hole of the tightening strap into the intended retainer. This compression cuff has the following advantages:     1) no more compression bandages which are often painful,   2) no painful compression of the artery, 3) on use of the compression cuff it is no longer necessary to ligate an injured limb because the compression cuff ensures continued flow of blood. At the same time, the limbs below the injury are still supplied with blood, so that they are spared from becoming necrotic, 4) quicker, simpler application as compared to a compression bandage,   5) a wider field of application, e.g. in shot wounds, arterial rupture and stab wounds. In shot wounds and stab wounds in the abdominal region the vacuum can be retained due to quick and tight application, 6) it can even be used by laymen without any problems and without harm to the injured person.   <IMAGE>
Patent DE-3135799-A1 (DE)
Title: Method of electric heating of cooled surfaces
Inventor: JOEST ULRICH
IPC: F25D21/04
Filed: 1981-09-10
Abstract: The invention relates to a method of electric heating of cooled surfaces to avoid condensate formation. In refrigerators and freezers, it is usual to design the heating in such a manner that, in the most unfavourable case, the temperature of the surfaces is higher than the dewpoint temperature, as a result of which, in the case of corresponding weather conditions, the electric heating is overdimensioned. In order to avoid this, the heating current is regulated depending upon the dewpoint temperature of the surfaces.
Patent DE-3137179-A1 (DE)
Title: Process for the production of an abrasive wheel
Inventor: NEUMANN HARRY DR ING
IPC: B24D18/00
Filed: 1981-09-18
Abstract: The invention relates to a process for the production of an abrasive wheel used, in particular, for grinding graphite electrodes for the electroerosion process. In this production process, a model evenly coated with an adhesive-repellant release layer is cast using a settable adhesive containing abradant particles. In order to avoid sharpening of the abrasive wheel, it is proposed that the abradant particles are allowed to settle in a compacted manner adjacent to the release layer due to the action of external force and some of the abradant particles are allowed to penetrate the release layer.

Title: Multi-part universal joint shaft of adjustable length
Inventor: ARNTZ MANFRED ING GRAD
IPC: F16D3/38
Filed: 1981-11-11
Abstract: It is the object of the invention to improve a universal joint shaft as regards the connection of the profile tube to the yoke in such a way that maximum strength with optimum use of materials is achieved. This object is achieved by the fact that the beads (4) of the lemon-shaped joint tube are placed in the axial centre plane of the yoke arms (3) as the zone of maximum strength. To produce the yoke (1) according to the invention, the yoke arms (3) can be formed in a first operation in a plane perpendicular to their plane of action, for example by extrusion, forging or a similar process, and brought into their angled plane by a bending operation towards the inside. In another method, the yoke arms (3) can be attached to the yoke shank (2) in a known manner by welding. <IMAGE>
Patent DE-3148533-A1 (DE)
Title: Device for measuring the level in a vessel containing a liquid
Inventor: HEYWANG HERMANN DR
IPC: G01F23/24
Filed: 1981-12-08
Abstract: A device for measuring the level in a vessel containing a liquid comprises a measuring resistor (WI) and a reference resistor (WII), which are formed from metal layers (2 and 5, respectively) on an insulating film (3). The metal layer (2) of the measuring resistor (WI) has a number of constrictions (4). No warming of the measuring resistor (WI) takes place below the liquid level (7), and above the liquid level (7) the measuring resistor (WI) is chiefly heated at the constrictions (4). Since the metal layer (2) has a high temperature coefficient, the change in the resistance value is a measure of the level. The reference resistor (WII) serves to compensate the fluctuations in the ambient temperature. The device is particularly suitable for measuring the level in a fuel tank in motor vehicles. <IMAGE>
