Title: Automatic paper sheet cutting for laser printer-plotter - obtaining data regarding lengthwise cutting from plotter, and using sensor for transverse markings and processor contg. memory and  converter to activate cutter
Inventor: BAY OTTO DIPL ING
IPC: B26D11/00
Filed: 1992-11-28
Abstract: The sheets are cut according to markings on the conveyor corresp. to the cross-section of the sheet. A control unit (64) with an electronic memory and a converter picks up the information concerning the format to be cut. This information is lengthwise cutting data from the plotter (1). When the control unit receives and processes the signals, the cutting device is activated. A digital counter is provided so that the length cutter is only activated after a predetermined number of pulses. This ensures that the length cutting takes place only after cross-section or width cutting. Light barriers (10,12) connected to the control unit detect the start (10) and end (12) of the paper. USE/ADVANTAGE - For plotter or laser printer. Simple and secure coding for length cutting device.

Title: Power supply unit
Inventor: IRMLER WOLFGANG ING GRAD
IPC: H02M3/158
Filed: 1993-02-25
Abstract: In order to avoid power supply disturbances in the case of rapidly switching devices, in particular in the case of clocked converters, a power supply unit which reduces the disturbances can be inserted between the power supply and the switching device. A power supply unit of this type for a three-phase power supply has a three-phase bridge, to which two symmetrically interconnected step-up converters are connected on the output side. The inductors (5, 6) of the two step-up converters have a very low inductance so that the phase shift between voltage and current is kept small. Since the inductors (5, 6) are demagnetised very rapidly, the switches (11) of the step-up converters must switch correspondingly rapidly. Irrespective of the load on the terminals (12) and (13) at the output of the power supply unit, it is ensured that virtually no phase shift caused by the load occurs between current and voltage at the feeding phases of the three-phase power supply. <IMAGE>

Title: Process for the anisotropic etching of an aluminium-containing layer
IPC: H01L21/3213
Filed: 1993-05-27
Abstract: Aluminium-containing layers having a flank angle >/= 0 are produced by addition of a volatile hydrocarbon to the etching gas mixture in a plasma etching process. In this process, the hydrocarbon assists the side wall passivation so that even very fine structures can be anisotropically etched. Furthermore, in the case of aluminium-copper alloys, the formation of sparingly volatile, copper-containing etching residues is prevented.

Patent DE-4334959-A1 (DE)
Inventor: THIGPEN JAMES L
IPC: B05D3/02
Filed: 1993-10-13
Abstract: There is disclosed a method and apparatus for coating an electromagnetic coil, particularly stator coils (14) for an electric motor, with an insulating catalyzed resin material. The catalyzed resin material is a two component material comprising an epoxy resin and a catalyst. The catalyzed resin material is a free flowing liquid at a first temperature and begins to cure rapidly at a second elevated temperature. The stator coils (14) are first heated by supplying current to the stator coils (14) to raise the temperature of the stator coils to the first temperature. The free flowing liquid catalyzed resin material is dispensed through nozzles (56, 60) onto the stator coils (14) as the stator coils (14) and the nozzles (56, 60) move relative to each other. After the liquid catalyzed resin material has been dispensed in a predetermined amount, at predetermined locations, for predetermined times, the catalyzed resin material is allowed to penetrate the stator coils (14). The temperature of the stator coils (14) is then raised to  the second temperature at which the curing of the catalyzed resin material occurs rapidly. As the curing continues, heat is produced by the curing process, and the current to the stator coils (14) is shut off at a predetermined temperature.

Title: Winding former for fuze links
Inventor: DROTHEN MICHAEL
IPC: H01H85/18
Filed: 1993-10-22
Abstract: The invention relates to a winding former (10) for a fuze link having a housing for the accommodation of fuze link conductors and two electrical connections. According to the invention, a groove (14 to 20) which runs in a helical shape is provided on the circumference of the winding former (10), in which groove a fuze link conductor can be arranged. In consequence, the axial separation between the turns of the fuze link conductor can be reduced, and the size of the winding former overall in the axial direction can thus be reduced. On the other hand, the length of the fuze link conductor can be correspondingly increased with the length of the winding former remaining the same. <IMAGE>

Filed: 1994-07-10
Abstract: An automatic revolving-door drive is described which has a hydraulic piston/cylinder unit 7, 8 with closing spring 10 and an opening motor 5 and a hydraulic pump 4. The piston 7 is displaceably guided in the hydraulic cylinder 8 while forming a pressure space 12 and a pressureless space 11 with a hydraulic connection 44 in which a stop valve 40 is arranged which is closed during the opening action and open during the closing action. This function of the stop valve 40 is the precondition for the opening action to be hydraulically effected via the pump 4 and for the closing action to be hydraulically damped via the closing spring 10. Provision is now made in a novel way for the stop valve 40 to be hydraulically controlled. For this, the stop valve 40 is connected to the pressure side of the hydraulic pump 4. It has a piston-shaped valve member 41 controlled via the hydraulic pressure. <IMAGE>
