Patent DE-4311219-A1 (DE)
Title: Method and circuit arrangement for protection against uncontrolled acceleration of an electronically regulated drive motor for fully automatic washing machines
Inventor: PATZIG JUERGEN DIPL ING
IPC: D06F34/08
Filed: 1993-04-05
Abstract: The invention relates to a method for protection against uncontrolled acceleration of a drive motor for fully automatic washing machines resulting from failure of the control electronics, the actual value of the rotation speed obtained from a tacho alternating voltage being compared with a desired value of the rotation speed, and the drive motor being turned off if the rotation speed is exceeded. In addition, an actual value which rises with the motor running time is compared with a threshold value. However, this threshold value is not reached during a reversing cycle of a washing or rinsing process, and the actual value is set to zero again. However, the threshold value is reached during the smooth starting phase of a spinning process as a result of the resetting remaining off, and the drive motor is still prevented from being turned off before the acceleration. The advantages achieved by the invention are, in particular, very extensive, reliable and cost-effective protective turning off. The invention is not linked to a specific regulator module but, since it operates completely separately, is suitable for retrofitting to complete washing machine regulators, in the form of a safety module (Fig. 1). <IMAGE>

Title: Brush making machine with aperture position inspection appts. - uses programmed control of translation and elevation of stuffing tool to compensate for positional tolerances of apertures in brushes
Inventor: BOUCHERIE LEONEL
IPC: B23Q15/24
Filed: 1993-04-14
Abstract: A stuffing tool (1) is used to insert bundles of bristles into apertures of a brush body (2) which is positioned w.r.t. the tool by a drum (3) carrying four bodies at a time and rotating in steps under the control of an electric motor (15). The position of the apertures w.r.t. the outer edge of each brush is checked by a mechanical or optoelectronic measuring device (26) (using e.g. laser, camera, etc) wired to the programmable controller (13) of orthogonal movements (X, Y) of the tool carrier. ADVANTAGE - Exact position of apertures in brush bodies is much less critical and injection moulding need not be so precise.
Patent DE-4312095-A1 (DE)
Title: Permanent laser marking of object - is used to produce invisible marking on non-metallic, valuable or important object e.g. IC housing, optics, currency or artwork for security and/or identification
Inventor: FISUN OLEG IVANOVICH
IPC: B44C1/22
Filed: 1993-04-08
Abstract: Permanent laser marking of an object is carried out by irradiating a sample of the material of the object with coherent radiation over a frequency band region which includes the expected spectral absorption region of the material. The region of max. spectral absorption of the material is determined within the frequency band region. The desired object region is locally irradiated with coherent energetic laser light of a wavelength near the resonant wavelength of the material and of an intensity high enough to produce a permanent marking. The appts. exhibits a modified optical effect in the visible and/or non-visible light region, but does not produce permanent thermally induced change in the object material. ADVANTAGE - Markings, which are invisible and which cannot be destroyed or easily copied, can be produced on almost any non-metallic object without any chemical or mechanical pretreatment.

Title: Inductive sensor
Inventor: HAAGEN THOMAS
IPC: G01D5/20
Filed: 1993-07-22
Abstract: In an inductive sensor having an approximately tubular coil former (1), pieces of wire with square cross section are inserted as contact tabs (10, 11) into receptacles (12, 13) of the coil former (1) which in each case have a bent-away end (19, 20) and on the opposite side a connecting end (8, 9).

Title: Device for making common electrical contact between a plurality of units, which can be excited (energised) electrically, of internal combustion engines
Inventor: ROMANN PETER DIPL ING
IPC: H01R12/77
Filed: 1993-08-03
Abstract: In the case of known devices for making common electrical contact between a plurality of units which can be excited electrically, in the case of which units printed circuit boards are used, an increased cost results from the design of a multi-piece housing and from the incorporation of conical contact fingers into holes in the printed circuit board, into which holes contact pins of the inserted units engage. The physical height of the device in the direction in which the units extend is further increased by the bending-off of the printed circuit board in the region of a connecting plug. As a result of the small physical volume of the printed circuit board (1), the housing (3) and the plug (7), the new device has only a comparatively small space requirement. The units, in this case fuel injection valves (2), are directly connected to the printed circuit board (1), via their contact pins, without any additional components. The plug (7) is designed such that it is not located, or is only insignificantly located, above the plane of the printed circuit board (1) so that the device has a physical height which is very small, seen in the direction in which the fuel injection valves (2) extend. The device is particularly suitable for making common electrical contact between fuel injection valves which can be operated electromagnetically. <IMAGE>

The bore surface 17) is extended in a radial extension (23) whose region (23b) parallel to the bore surface (17) is removed from it by a distance (d) corresponding to the cutting stroke in the insulation material (13). At the start of the cutting process, the bore surface (17) is covered by a guide part (2) which can be removed from the cable. This part (2) has a bore (20) of the diameter of the insulation (13), centred about the fibre bore (16) axis. The guide part (2) guides the cable (11) until the cutting body (1) is driven by a rotation. The cable is securely guided by the bore.

Title: Heating resistance control device for thermal process printer
Inventor: OBSTFELDER GUENTHER
IPC: H04N1/40
Filed: 1994-02-18
Abstract: The device has a processor chip which prepares control information and data, and an output driver block (7) to drive the heating resistances in the print head. A stepping transport mechanism moves the information carrier (paper) through the printer. A bit storage block (1) in the processor chip contains a register (1.0-1.5) for each binary grey level or colour value. Data lines (D1N1-D1N5) feed binary grey scale or colour values into the bit storage block registers. An external system clock (SYSCLK) and a control block (2) are used to process a factor which is decoded from a command word and combined with the system clock to determine the unit time period for the lowest grey level. A bit evaluation block (3) uses this time period with the contents of the registers to drive the heating resistances via the drive block for the appropriate length of time.
