Patent DE-2028960-A1 (DE)
Title: Yarn false twist unit
IPC: D02G1/04
Filed: 1970-06-12
Abstract: The false twisting unit features a heater followed by a cooling zone in front of the roller with rubber cover offering a high friction to the yarn.

Patent DE-2034485-A1 (DE)
Title: Warp monitor - using divided laser beam under the warps for breakage to be converted to a stop signal
IPC: D03D51/28
Filed: 1970-07-11
Abstract: A laser beam is split by mirrors into two parallel narrow beams under the warp yarns. Each beam is received by a photo-electric cell, both linked to a detection unit. If a warp yarn breaks, it falls and breaks the two beams in rapid succession, this pattern being converted by the detector into a stop signal to the loom. The use of fine laser beams allows yarn break detection when the warps are of fine-gauge yarns.

Title: Electric aquarium heating control - varies gate pass factor by photoresistor aligned with glowlamp controlled by thermistor
Inventor: SCHLOEMP REINHARDT
IPC: G05D23/24
Filed: 1973-07-05
Abstract: The electronic temperature control for aquarium heating systems is inexpensive to produce. It has small dimensions and combines a reliable temperature monitor with a heating power control. The thermistor which has a negative temperature coefficient and acts as the temperature probe is linked to a glow discharge lamp which emits radiant energy when the temperature drops below a certain value. This is sensed by a photoresistor which increases, with increasing radiation energy, the pass-through factor for a stepless variable gate, consisting of a triac and a diac. The gate in turn governs the heating power of the heating element.

Title: D.C. HV generator with diode and capacitor HV cascade - is supplied from mains via input transformer over triac controlled by comparator
Inventor: RAAB KLAUS
IPC: G05F1/455
Filed: 1973-07-26
Abstract: The Hv generator for 1000V from a 50 Hz mains supply, has its input transformer secondary coupled over a triac power switch to a HV multiplier cascade consisting of diodes and capacitors. The cascade HV output is divided and passed back to a comparator, where it is compared in amplitude with the output of a sawtooth generator. The sawtooth generator is synchronised with the supply frequency and that of the oscillator at twice the latter frequency, i.e. 100 Hz. The comparator output produces control pulses whose width depends upon the amplitude difference between the sawtooth and HV output waveforms. The control pulses are applied to the triac gate.

Title: Control for driving simulator - has two variable speed orthogonal drives for camera over model depending on model scale
Inventor: WAND ALBRECHT DIPL ING
IPC: G03B15/00
Filed: 1973-11-14
Abstract: The driving simulator has a TV camera mounted on a special support so that it can move in two orthogonal directions using a travelling gantry system. An optical extension is mounted in front of the camera objective with a mirror at the bottom. This enables the camera to view the scale model of the simulator in any direction and in simulated positions for drivers and pedestrians. The simulated image is displayed on a video monitor, while the movement of the camera is controlled by a control console. The speed control for the two orthogonal directions is derived from sine-cosine function generators, with the electric drive motors coupled to variable resistors to alter the scale of the drive w.r.t. scale of the model.

Title: Sack mouth closing machine - has swing frame with arm delivering and pressing mouth into die
Inventor: DOBBERT ARNOLD EDWIN
IPC: B65B51/00
Filed: 1973-12-06
Abstract: The machine presses and clamps the edges of the sack mouth together before fitting a fastener. A die on a support accommodates the mouth and a frame swings on the support between an open position and a closed one near the die. A long arm mounted near one end of the frame swings to and from the die so as to move the mouth onto it, and a rucking unit on the arm has an edge by which the mouth is forced in a direction at right angles to that in which the arm moves it. The rucking unit can pivot on the arm on placing the mouth in the die, and can move under gravity from the outer to the inner position. The arm can actuate an ejector plate removing the mouth from the die after the fastener has been fitted.
