Title: Device for measuring the circumferential speed of a vehicle wheel
Inventor: FINKE JUERGEN DIPL ING
IPC: G01S13/60
Filed: 1988-04-08
Abstract: The knowledge of the wheel circumferential speed which is required for controlling braking slip (skidding) (ABS, ABV) and/or drive slip (ASR) is normally determined indirectly by measuring the wheel rotation speed or by inductive detection of the wheel angular velocity. This speed determination is dependent on the wheel diameter and is subject to certain interference influences. Furthermore, it is necessary to match the design to the vehicle wheels and to the associated axle parts. In order to be able to measure the circumferential speed of the vehicle wheels independently of variations in the wheel diameter and, furthermore, to be able to use mass-produced components, which do not need further matching, for vehicle wheels and for the axle parts, the circumferential speed of the vehicle wheel is measured with the aid of a microwave Doppler sensor which is mounted on the vehicle structure itself in the plane of the circumference of the vehicle wheel and whose horn antenna is directed at tread of the vehicle wheel. The novel device for measuring the circumferential speed can advantageously be used for controlling braking slip and/or drive slip. <IMAGE>

Title: Field-effect controlled, bipolar power semiconductor component, and method for producing it
Inventor: BAUER FRIEDHELM DR
IPC: H01L29/423
Filed: 1988-06-18
Abstract: In a field-effect controlled, bipolar power semiconductor component of the IGR (Insulated Gate Rectifier) type, the latch-up problems associated with the parasitic thyristor elements are solved by limiting the periphery of the n-regions (5a...e) of the n-emitter layer (5) by means of low-resistance p<+> zones (9), on the one hand, and by arranging the gate electrodes (7) in trenches, on the other hand. A critical voltage drop of the lateral hole current in the p regions (4a, b, c) of the p base layer (4) is avoided in this way. <IMAGE>

Title: Process for the preparation of hexafluoropropene
Inventor: SCHOETTLE THOMAS DR
IPC: C07C17/26
Filed: 1988-07-09
Abstract: A process is described for the preparation of hexafluoropropene by thermal cleavage of chlorotetrafluoroethane and perfluorocyclobutane at 600 to 1000@C under pressure of 1 to 1000 kPa. The thermal cleavage reaction is carried out in the presence of at least 0.05 mol of tetrafluoroethene per mol of chlorotetrafluoroethane and perfluorocyclobutane. This allows hexafluoropropene to be obtained with relatively little additional equipment but in good selectivity and with an improved space-time yield; an azeotropic mixture of chlorotetrafluoroethane and perfluorocyclobutane, which is obtained during work-out of the products of chlorodifluoromethane pyrolysis, can be used in an advantageous manner.

Title: Method of producing an individual nose mask for the artificial respiration of a patient
Inventor: LAIER-GROENEVELD GERHARD DR
IPC: B29C33/38
Filed: 1988-12-01
Abstract: For the production of an individual nose mask for the artificial respiration of a patient, a mask body (8) which bridges the nose, especially in the region of the nostrils, and rests sealingly against the neighbouring region is individually shaped. Two holes for insertion and connection of two respiration tubes (9) are drilled in the mask body, and eyelet-like perforation (11) for the attachment of retaining straps (12) are formed. This entails an impression model of the nose of the patient being made, and this is used to form a positive, non-resilient nose model. The nose model is used to shape the mask body (8) and to connect, permanently as regards direction and projection, the respiration tubes (9) sealingly to the mask body.   <IMAGE>

Title: Ink-ribbon device for typewriters or office machines of similar design
Inventor: WITTKE SVEN
IPC: B41J35/36
Filed: 1989-01-18
Abstract: The subject-matter of the invention is an ink-ribbon device in typewriters or similar office machines, wherein, after the ink ribbon has been used up, either a new ink-ribbon cartridge or else only a new ink-ribbon supply reel is inserted. In this case, it is now also possible for duplicated ink-ribbon cartridges or ink-ribbon reels to be inserted, whose ink ribbons do not have the quality required by the manufacturers of the machines. For example, such duplicated ink ribbons can cause rapid soiling of the machine or else cannot guarantee uniform printing quality. According to the invention, these disadvantages are avoided in that the ink ribbon is a carbon ribbon which is coated on one side and the start of whose ink ribbon has coded markings which can be scanned by the scanning device to trigger control signals in a control member. It is thus ensured that only ink ribbons approved by the manufacturer of the machines can be used. At the same time, the step width of the ink-ribbon transporting step can also be controlled by means of the coding at the start of the ink ribbon. The end of the ink ribbon can likewise be indicated to the operator at an early stage by means of a coding at the end of the ribbon. <IMAGE>
