Patent DE-4204351-A1 (DE)
Title: DC supply driving circuitry for three=phase sync. motor - feeds stator with overlapping blocks of square wave current pulses modulated by exponential wave
Inventor: ALBRECHT JOERG DIPL ING
IPC: H02P6/14
Filed: 1992-02-14
Abstract: To drive a three-phase sync. motor from a DC supply, the individual stator phases are connected to the supply by semiconducting switches controlled by a commutating device. Depending on rotor position, phase shifted signals are generated to trigger the opening and closing of the switches. The leading and trailing edges of the stator current pulses are adjusted in a pulse shaping circuit so that there is an overlap (in time) between one pulse switching off and the next one switching on. The modified pulses then modulate the output of a square wave pulse generator before it is passed to the switches. The switching is executed by using the unmodulated output of the pulse generator. ADVANTAGE - Inexpensive circuit giving reduced commutation noise and good speed control.

Title: Determining time ot heat melt in furnace to casting temp. - by comparing actual heating parameters with those obtd. during previous heating process, using full melt holding vessel
Inventor: GASCH HORST DIPL ING
IPC: B22D2/00
Filed: 1992-03-19
Abstract: Determining the temp. rise during the heating of molten metal in a vessel inside a heating furnace consists of comparing the actual working parameters which exist during heating with those parameters measured during a previous heating process using a full holding vessel and calculating the temperature rise per unit time to enable the time required to heat to a predetermined temp. to be calculated. Calculating of the temp. rise is started once the initial temp. of the melt has been determined. At this point the heating by the furnace is started and the calculated heating rate used to determine the time required to reach the casting temperature. After this determined time the furnace heating is stopped. USE/ADVANTAGE - Heating melts to the required casting temperature. There is no need to monitor temperatures with traditional measuring devices e.g. measuring lances.

Title: Prodn. of plastics=processing tool with microtextures - by making flat die with microstructures forming thick metal plating on the die, fixing to backing plate and then removing
Inventor: KALB HELMUT
IPC: B29C33/42
Filed: 1992-12-04
Abstract: A metal tool with micro-textures for use with plastic materials is produced by starting with a die plate with microstructures which include gaps on an electrically conducting base and which complement the microtextures; with the conducting base used as cathode the plate is treated electrolytically until the gaps as well as the microstructures are coated with a layer of the metal, and the metal is then removed from the plate. In the process the microstructures are covered with metal 0.5 to 4 mm thick; before removing the metal from the die the side of the metal opposite to the microstructures is fixed to a backing plate. ADVANTAGE - The method shortens times for the electrolysis. It produces a smooth tool. It minimises any risk that stressed areas of the product will split off, despite the short times concerned.

Title: Warp-knitted fabric with pile and process and warp-knitting machine for producing it
Inventor: WEILAND JAKOB
IPC: D04B23/08
Filed: 1993-04-20
Abstract: A warp-knitted fabric with pile is produced. The basic fabric is produced by means of a first basic knit, in which each thread (11) forms stitches (18) at a spacing of n stitch wales (19), and by means of a second basic knit, the threads (10) of which form a uniform weft knit. The pile is formed by a pile knit, in which each thread (12) forms stitches (18) at a spacing of m stitch wales (19). Here, n is at least equal to 1 and m at least equal to 0. In a process for producing a warp-knitted fabric, the weft knit is guided in such a way that its knitting movement has reversal points at a spacing of approximately (n + 1) needle divisions. A warp-knitting machine possesses a first basic-knit bar (L2), a second basic-knit bar (L1), a pile-knit bar (L3) and a pile-sinker bar (PB) with associated racking control devices (14 to 17) which work with the effect of the abovementioned racking movements. <IMAGE>

Title: Mini-disc recorder-player with high speed copying - provides magneto=optic recording with error correction and copy protection
Inventor: ENDO KAZUHITO
IPC: G11B27/00
Filed: 1993-04-15
Abstract: The mini-disc system has an intermittent record mode in which input signals are digitised and compressed to 1/5 of their volume, and error detection codes are added. In copy mode, a switch is set to receive an input data stream from a replay signal processor which delivers an error corrected data stream. The controlling microprocessor switches the mode to continuous output at the disc data rate so that no gaps in the stream are present. The signal passes through an ECC encoder (5), a modulator (6) for EFM (e.g. from eight to fourteen) modulation and to the magnetic record head (8). A copy protection code detector in the replay circuit prevents this transfer when copy protect is set. USE/ADVANTAGE - High speed copying of data at multiple of normal replay rate.

Title: Sensor device
Inventor: BENDICKS NORBERT
IPC: G01N21/43
Filed: 1993-06-01
Abstract: A sensor device is proposed for measuring the degree of wetting of a transparent screen, made of a plurality of layers and preferably consisting of glass, with, in particular, drop-shaped precipitation, which device is provided with a beam-guide body having two mutually associated beam windows and cooperating with a beam emitter and a beam receiver. In order to prevent interference beams produced by a very thin intermediate layer located in the screen from having a tangible (nominal-value) influence on the signal used for controlling the screen wiper system, it is proposed for the beam-guide body to have an additional beam-output window in the central region, located between the two mutually cooperating beam windows, of its rear surface remote from the screen, which beam output window being assigned to the measurement path and cooperating with an additional beam detector, such that only the interference beams reflected at the very thin metallic intermediate layer located in the screen leave this window and such that the signal, from the additional beam detector resulting from the emerging interference beams is employed for correcting the signal delivered by the actual beam detector. <IMAGE>
