Title: Speed controller for rotary cutter - has thyristor responsive to speed command, follow up error and acceleration signals
Inventor: SAITO MINORU
IPC: B23D36/00
Filed: 1977-11-10
Abstract: In the rotary cutter speed control system a function is generated in response to the material travel pulses which are counted up or counted down in accordance with the acceleration/deceleration coefficient and the rotary cutter speed control pattern. In addition, the speed control function is multiplied by a material travel speed obtained by converting the material travel pulses. The material travel speed is then added to the resulting product to generate a rotary cutter operating speed command signal. A cutter follow-up error signal and an acceleration signal are generated and used with the speed command signal to control the cutter-driving DC motor via a thyristor Ward-Leonard arrangement.

Patent DE-2822426-A1 (DE)
Title: Decorative self extinguishing wax candle - with tongs gripping spiral wax strand near wick end
Inventor: SCHAMBERGER HUBERT
IPC: C11C5/00
Filed: 1978-05-23
Abstract: A decorative candle consists of a disc with feet and a central column, around which a long thin strand of wax with a wick in the centre is wound in a multilayer steep-pitched spiral. The end of the strand is held at a certain distance from the protruding wick by two thin arms of spring-loaded tongs. The distance from the free end to the tong application fixes the length of time before the candle extinguishes itself because the heat softens the wax and the arms pinch together thus preventing further wax from having access to the flame. Such a candle is simple and safe to use. The desired lighting time can be readily set.

Title: Mixing stage with oscillator frequency coupling via reactance - has FET and capacitance diode between secondary circuit of input band filter and mixer input
Inventor: ENGLMEIER MARTIN DIPL ING
IPC: H03D7/12
Filed: 1978-10-25
Abstract: The mixer is formed by a F.e.t. in a stage with a capacitively coupled oscillator. The stage is provided with coupling of the oscillator frequency, via a reactance element, and is intended for a receiver input circuit which can be tuned in a greater frequency range. A capacitive diode is between the secondary circuit of the input band filters and the mixer input. Across a resistor, a tuning voltage is supplied to the diode, while an inductance is incorporated between the oscillator output and the mixer input. The oscillator circuit is pref. tunable by voltage dependent capacitive diodes, for which the tuning voltage serves simultaneously as the control voltage. This mixing stage enables improved coupling of lower oscillator frequencies. When using a f.e.t. the high input capacity restricts considerably the tuning range, while at lower circuit capacities the amplification is highly increased by the high ohmic character of the circuit.

Title: Tape prodn. by broadloom with hot-wire slitter - using heated temple-bar to set broad fabric at reed-width
Inventor: MAROWSKY RUTHARD
IPC: D03J1/08
Filed: 1979-02-14
Abstract: A loom for the prodn. of synthetic tapes by hot-wire slitting of a broad fabric has a temple-bar extending across the full width of the loom immediately behind the fell which incorporates an adjustable heater.

The fabric is sufficiently set by the heated bar to retain a flat, straight form despite a relatively long gap between it and the slitter. The slitting produces long, straight cuts, perpendicular to the weft, right to the edges of the broad fabric.
