Title: Projectile loom - has checking mechanism which measures pressure in gap beneath bottom swell with pressure sensor
Inventor: GREGER WOLFGANG
IPC: D03D49/54
Filed: 1988-10-03
Abstract: On a projectile loom the checking mechanism control has pressure measurement during the time the projectile is in the swells. This is operated in conjunction with the loom shaft angle. The projectile pref. enters the checking mechanism, and the amount of control depends on the measurement of pressure in the gap beneath the bottom swell by the pressure sensor.  The position to the extractor mechanism is measured by sensor. The information is relayed to a logic circuit, programmable to retain the correct distance, by picking up information from the indicator on the loom shaft, in addition to the two sensors, so that output from the controller to the motor can adjust the swell mechanism.  The logic circuit is also connected to the loom circuitry.  This means that there is constant feedback, and instantaneous monitor in the system. This is necessary on account of the various factors affecting the loom, i.e. temperature, or oil on the projectile. ADVANTAGE - damage to projectile, or the braking system is avoided. weft is not released prematurely.

Patent CH-647335-A5 (CH)
Title: Circuit arrangement for the intrinsically safe monitoring of a voltage
Inventor: DZAMKO OLEG
IPC: H02H3/24
Filed: 1979-05-08
Abstract: The intrinsically-safe monitoring circuit continuously compares a stabilised threshold (U1) and a threshold (U2) fluctuating proportionally to the value of the voltage to be monitored (U0) with the magnitude of sawtooth pulses (22). A following coincidence circuit (28) outputs output pulses when the sawtooth pulses reach both comparison thresholds approximately at the same time. The output pulses activate an evaluating circuit (33) via a DC-isolation stage (31). This evaluating circuit extinguishes the alarm lamp (35) as long as it is reached by pulses. If one of the comparison thresholds (U1, U2) drifts away, the sawtooth pulses no longer reach both thresholds at the same time. They thus output their output pulses shifted in time and the coincidence circuit (28) no longer responds. This leads to the alarm lamp (35) being switched on. <IMAGE>

Title: Process for reclaiming reusable components from synthetic polymer wastes
Inventor: KURISU SHINGO
IPC: C10G1/02
Filed: 1975-06-20
Abstract: An industrially applicable utilisation, which is as complete as possible, of synthetic polymer wastes is made possible by a method in which, in four process steps, the wastes are, in a first step, heated in a decomposition unit (14) to their molten state, the gases thus obtained being led off via a cooling apparatus (10). In a second step, the melt is thermally decomposed at 350-500 DEG C in a decomposition unit (5). The liberated gas is led off via a condensation apparatus (11). The third step represents the cooling of the led-off gases to room temperature and the separation thereof into gaseous and liquid components which are collected in vessels (21, 22). Finally, the separation of the residues from the unit (6) into liquid and solid material takes place, a centrifuge (9) being used for this purpose. The liquid material is fed back to the decomposition unit (6). The solid components are used together with a part of the gaseous or volatile hydrocarbons for heating the blast heater (25) which serves as the heat source. <IMAGE>

Title: Method for the selective setting of operating characteristics and operating modes of an electromechanical multi-function relay
Inventor: HAUSSENER HANS
IPC: H01H50/14
Filed: 1976-07-01
Abstract: In switching installations of an industrial concern, for example in which motors or other electrical operating installation parts are switched on and off by means of multi-function relays via electromechanical switches, it is desirable that those relays which have become defective or otherwise unusable can be made serviceable again or replaced quickly and without long interruptions in operation. A simple method is expedient, in the case of which only wire connections between closely adjacent terminal connections of a fixed-position plug and connection device need to be made by hand. This time-saving method for selective setting of a desired operating characteristic or operating mode of a relay is particularly expedient in the case of repairs or operating mode changeovers which are linked to the relay in operation, since they can be carried out without any major interruptions in operation.
