Title: Interference-proof proximity switch
Inventor: SOYCK GERNO
IPC: H03K17/945
Filed: 1996-07-17
Abstract: The proximity switch comprises an oscillator circuit (1) which operates via a useful signal analysis circuit (2,4). Parallel to the analysis circuit and via an interference signal generator (6-10) a lockable latch circuit (5) is connected before the end stage. A far field probe (R) couples the negative terminal of the voltage supply of the switch at the position of the interference signal generator via a resistor to the output (22) and via the diode with the input (20) of the latch stage of the latch circuit. The far field probe is preferably an electronic sensor or a magnetic field dependent rest contact. The probe is preferably reaction sensitive with respect to its response and switching time, as the sensing element of the proximity switch.

Title: System for controlling self-clocked stepping motor e.g. of printer
Inventor: MOELLER SIEGFRIED
IPC: H02P8/04
Filed: 1996-08-22
Abstract: A method for controlling a self-synchronising stepping motor which reacts to the braking effect of an imposed load is regulated by a controller to ensure that after starting it accelerates to a required preset speed/stepping frequency. The motor (1) drives the take-up rollers (10) in the sheet stacker (7) of a printer or copier (6) which ejects each printed sheet (12) via the exit rollers (8) to the guide (14) and sheet sensor (16) en route to the take-up rollers (10) and finished output (8). The running speed is continuously monitored and if observed to remain below a certain threshold for a limiting period, a revised (higher) speed/stepping frequency is automatically adopted pending load reduction.

Patent DE-19651626-A1 (DE)
Inventor: WARNER REUBEN BROWN
IPC: B29C70/02
Filed: 1996-12-12
Abstract: Honing tools (90) and methods of making such tools utilize a compact bundle (92) of abrasive containing plastic monofilaments projecting a relatively short distance from the holder with the compacted tips forming the working face (93) of the tool. The bundle may be secured to the holder by a thin layer of the adhesive or by a clinched or swaged girdling lip or rim on the holder which embraces the bundle. In addition, the bundle is further infused with an elastomer, preferably foamed. The bundle is enclosed in a mold (94, 95) which may be part of the clinching process and an elastomer is injected into the mold to infuse and encapsulate the bundle. The encapsulation fills the interstices of the bundle and form an integument around the bundle in effect making the tip action tool into a solid yet elastic block. This enables the abrasive monofilaments to have a higher abrasive loading since they are additionally supported by the matrix, and the tool to be applied at higher pressures. The matrix may be injected through the working face, the bottom of the holder or through the mechanical anchor holes in the sides of the holder.

Patent DE-19711529-A1 (DE)
Inventor: BACH HANS FRIEDRICH PROF DR
IPC: B01D53/68
Filed: 1997-03-19
Abstract: The invention relates to a two-stage method for removing harmful acid substances from the waste gases produced by furnaces or fusion processes. In the first stage, a fine-particle additive consisting of calcium carbonate or calcium hydroxide is added to the waste gas at temperatures of 800 to 1250<o>C. The pre-cleaned waste gas is then re-treated in a self-cleaning reactor located downstream, optionally by adding water or water vapour, by means of intensive mixing at temperatures of 60 to 300<o>C. Said additive consists preferably of 80 to 95 weight per cent precipitated calcium carbonate and 5 to 20 weight per cent graphitic carbon and can also contain up to 5 weight per cent organically bonded nitrogen. This technique of combining a dry-additive and dry-sorption process and using a self-cleaning reactor provides a reliable means of eliminating the additive/fly ash deposits in installations which have been the cause of so much concern until now, with overall separation efficiency rates of up to 90 %.
