Title: Method of signalling faults in quick-change tap chucks by means of an infrared remote control system
Inventor: MEINL GERHARD DIPL ING
IPC: B23G1/26
Filed: 1987-09-28
Abstract: To signal faults in quick-change tap chucks, a battery-powered infrared transmitter fitted into the chuck is used instead of the hitherto realised method via limit or proximity switches, with the cable feeds put at risk by chip formation, or the transmitters, which can only be screened at great expense, in the method by means of radio signals. It is distinguished by battery-saving operation, low manufacturing and part costs on the one hand and low inventory and spare-parts stockkeeping costs on the other hand (both at the manufacturer's and the customer's), the latter owing to the fact that in standard application a single frequency of all chucks of an automatic production machine is sufficient.

Title: Method for measuring the attenuation changes in optical fibre cables during manufacturing processes
Inventor: SITTIG KONRAD DIPL ING
IPC: G01M11/00
Filed: 1988-01-04
Abstract: The method for measuring the attenuation changes in optical fibre cables during manufacturing processes relates to the optical fibre cable production industry and to the reduction of waste production. According to the invention this method is realised in that the material to be measured is transilluminated in such a fashion that a constant luminous flux is received on the receiver side. The transmitter is controlled by a control loop such that variations in attenuation are compensated for by means of corresponding changes in the transmitter power. In the control loop, a luminous flux desired value is specified, which is compared with the receiver flux, integrally evaluated and fed to the current source controlling the transmitter. The transmitter flux at the time of beginning manufacture is stored and, during the production process, divided by the instantaneous transmitter flux and the ratio is indicated in decibels.

Title: Thermal printer with a thermal print head arranged on a movable carriage and an ink-ribbon cartridge
Inventor: LANGE HEINZ
IPC: B41J33/52
Filed: 1988-03-05
Abstract: In thermal printing mechanisms with thermal print heads which have individually heatable heating elements for producing individual printing dots on the recording medium by means of a thermal transfer ink ribbon (7), it is necessary for the ink ribbon (7) to be guided tautly in the printing region. For this purpose, in known thermal printing mechanisms, a ribbon tensioning device serving as a brake is arranged before the thermal print head in the running direction of the ink ribbon (7), which ribbon tensioning device has a pressing-on plate which presses the ink ribbon (7) against a guide. Since this pressing-down plate (56) interacts with the side of the ink ribbon (7) having the meltable ink, it must be exchanged from time to time for reasons of soiling. This exchange of the pressing-on plate (56) is facilitated according to the invention in that it is arranged releasably by means of a bearing arm (58) of a swivel lever (49) by means of resilient catch arms (63, 64) which can be engaged with catch lugs (59, 60) in catch notches (61, 62) of the bearing arm (58). The catch arms (63, 64) have actuating handles (75, 76) which are arranged so that they can be pressed together to disengage the catch arms (63, 64). The pressing-on plate (56) can be exchanged without any particular skill by any operator of the machine. <IMAGE>

Patent DE-3818079-A1 (DE)
Inventor: RUNGE ERICH
IPC: B28D1/14
Filed: 1988-05-27
Abstract: A milling tool is proposed, in particular for powered hand drills and hammer drills, for underreaming drilling holes while forming conical widened portions or undercuts, in which milling tool the milling head, displaceable in the axial direction, is connected to the tool shank suitable for accommodation in a drill chuck, and in which a movably arranged cutting tool, which in the normal position of the tool is completely sunk in a longitudinal groove, emerges from its circumferential surface in a radial direction transversely to the longitudinal axis of the milling tool as soon as the axially displaceable parts, namely the shank and the milling head, are moved towards one another. This ensures that conical widened portions or undercuts of cylindrical bores formed previously in a conventional manner, with regard to their location and their geometric form, are formed completely irrespective of actions of the tool user. Furthermore, this ensures that heavy-duty anchors carrying a cone can be inserted in an accurately fitting manner into the conically widened or undercut bores thus produced. The proposed method is characterised by the use of the milling tool according to the invention. <IMAGE>

Title: Method and device for the removal of soot deposited in an exhaust-gas filter of an internal combustion engine
Inventor: HENKEL DIETMAR ING GRAD
IPC: F01N3/30
Filed: 1988-05-28
Abstract: The invention relates to a method including a device for the removal of soot deposited in an exhaust-gas filter of an internal combustion engine, the exhaust gas in the area of the filter experiencing a temperature increase as a result of adiabatic changes in state (compression), such that the soot deposited in the filter is brought to combustion. In order at the same time to avoid unwanted reactions of the generated counterpressure on the charge cycle and the exhaust work of the engine, the adiabatic temperature increase is produced by the forcing of a pulsating pressure working in the resonance state. In this, a resonance system is connected upstream of the filter and the excitation pressure for the resonance system is generated either by a pulsating burner flame or by periodic opening and closing of the exhaust outlet passage by means of a flap.
