Title: Device for subsequently fitting (retrofitting) a measurement connecting stub to a cable on which compressed air acts
IPC: H02G15/26
Filed: 1983-06-16
Abstract: In the case of a device for subsequently fitting a measurement connecting stub on a cable on which compressed air acts, having a baseplate which can be fixed on the cable surface (possibly via a shrink sleeve) and has a connecting stub for a manometer, and has a valve within the connecting stub, it is intended to create a solution by means of which, on the one hand, the subsequent fitting of a measurement connecting stub is simplified, the fitting being selected such that the measurement connecting stub can remain where it was fitted all the time, the amount of air released when the measurement connecting stub is fitted and used continuing to be negligibly small. This is achieved in that it is equipped with a penetration channel (10) in order to penetrate the outer cable sheath (3), and in that the penetration channel (10) is guided in the connecting stub (5) such that it is sealed with respect to compressed air. <IMAGE>

Title: Interference suppression element in particular for ignition systems in internal combustion engines
Inventor: MARTH DETLEF
IPC: H04B15/02
Filed: 1983-10-08
Abstract: An interference suppression element, in particular for ignition systems in internal combustion engines is proposed, which serves to prevent the propagation of interference influences in the ignition system and additionally, in an electronic ignition system, protects the components from damage which can be caused by negative voltage peaks which arise when the ignition system is switched off. The said element contains a polarity-reversal protection which limits the current to a harmless value even when there is negative voltage in the system caused by reversal of the polarity of the battery. The interference suppression element (9) comprises a capacitor (10) which is located in the shunt (8) to the primary winding (3) of an ignition coil (4) and is combined with a diode (14) and a resistor (18) to form an assembly. The diode (14) and a resistor (18) form a series circuit which is in turn connected in parallel to the capacitor (10).   <IMAGE>

Title: Processing machine for webs of material
Inventor: KAMPF EBERHARD DIPL ING
IPC: B26D7/26
Filed: 1983-12-28
Abstract: A processing machine for webs of material, especially webs of film, which has guide rails extending inside a guide over the width of the machine and individual slots which are used for the reception of individual processing stations such as a cutting station, a pressure roller, a winding device and the like and which can be moved on the guide rails and can be clamped in an operating position. The technical problem lies in reducing the conversion times for adjusting individual slots on a guide on a processing machine of the given type and also in clamping of the individual slots which is load- and torque-free with regard to the guide rails. Clamping rails (5) with two clamping surfaces (6) which are aligned parallel to one another and opposite one another are provided inside the guide. Clamping devices (9) with brake cheeks (10) aligned opposite one another in pairs are assigned to the two clamping surfaces (6). Each clamping device (9) is coupled with a switching device, which places the clamping device in clamping and release positions. <IMAGE>

Title: Dental synthetic materials enriched with fluoride for caries prophylaxis
Inventor: MIETHKE RAINER-REGINALD PROF D
IPC: C08F2/44
Filed: 1984-02-09
Abstract: The invention relates to the use of modified dental synthetic materials in various areas of odontology. By combining the use of synthetic materials in dental appliances and the principle of fluoridation for caries prophylaxis, the intention is that the risk factor of caries susceptibility in debris niches is substantially eliminated. The practical procedure in the claimed invention comprises admixing up to 20% (% by weight) of fluoride salts, for example 10% CaF2, with the commercially available synthetic material prepolymer, which is in solid form, for the purpose of processing and hardening together on polymerisation with commercially available monomer liquids which are present. When slightly soluble fluoride salts (e.g. calcium fluoride) are used it is moreover possible to ensure a fluoride concentration in the saliva which is required for caries prophylaxis (e.g. for CaF2 10 ppm for several months).

Patent DE-3427465-A1 (DE)
Inventor: HELMREICH DIETER DIPL ING DR
IPC: C30B11/00
Filed: 1984-07-25
Abstract: A process and apparatus for the manufacture of silicon blocks having a columnar structure comprising monocrystalline crystal zones having a crystallographic preferred orientation. In a casting process, each mold filled with molten silicon is transferred, before the silicon has solidified completely, to a separate crystallization station where the silicon can then crystallize completely. During this process, the exposed surface of the silicon is maintained in a molten state until the end of the solidification process has almost been reached. The process allows the various, necessary steps to be carried out simultaneously and yields high-quality solar cell base material.

Title: Method for producing plug contacts having a large number of contact wires which are fitted on a carrier part in such a manner that at least one molecular fusion has taken place at the junction point
Inventor: MUELLER MICHAEL
IPC: H01R43/16
Filed: 1984-08-29
Abstract: The invention relates to a method for producing plug contacts having a large number of contact wires, which are fitted on a carrier part in such a manner that at least one molecular fusion has taken place at the junction point between the contact wire material and the carrier part material. In this case, the length of the contact wires is greater than the distance between the attachment points. A loop is thus produced. The wire loops thus formed can be fitted both parallel and at a specific angle in the axial direction. By means of this production technique, very thin wires can be used, for example having a diameter of less than (<) 0.008 mm.

Title: Thyristor with turn-off capability having an improved emitter region, and processes for the fabrication thereof
Inventor: TEMPLE VICTOR ALBERT KEITH
IPC: H01L29/74
Filed: 1984-12-22
Abstract: A thyristor comprises, in a semiconductor material wafer (106), a number of N<+>-type main emitter elements (142, 142'), generally parallel to one another, and, doped more weakly, N-type channel emitter elements (128) oriented transversely to the main emitter elements. The N<+>-type emitter elements can be formed without a critical alignment step, as they need only be oriented transversely to a number of gate electrode fingers (108, 108') in the upper part of the wafer. The N-type channel emitter elements are preferably brought into coincidence with the gate electrode fingers in such a way that narrow elongated regions are enclosed which make it possible to provide more N-type channel emitter elements for a thyristor of a given size. This increases the number of turn-off channels in both sides of the channel regions, as a result of which the level of the current which the thyristor can turn off by suitable biasing of the gate electrode fingers is increased. A P-type base region comprising a layer of increased conductivity relative to the upper surface of the P-type base region further increases the level of the appliance current which can be turned off by the thyristor. Processes for fabricating a thyristor having the abovementioned features comprise a process for forming the N<+>-type main emitter elements without a critical alignment step, a process for forming the narrow, elongated N-type channel emitter elements, brought into coincidence with the gate electrode fingers, and a process for forming the P-type base region comprising a layer of increased ...
