A weft 14 held between a clamp 17 and a suction tube 15 is pulled into and through a dummy shuttle 12 by a pivoted hook 16 that is moved by a cam 53 as the sley comes forward to beat-up. In a second embodiment (Fig. 8, not shown) the shuttle passes around a stationary forked member (42) from which the weft is removed by a cam operated hook (43). As the shuttle is picked the weft 14 is is drawn out of the suction tube 15, the lower leg of the weft loop passes under a beak 20 of the shuttle and the upper leg passes over the beak into a spring loaded clamp 22, 23 in the shuttle. The clamp 17 is then released and the shuttle carries the weft through the shed until shortly before its exit where upon the clamp 17 is again closed and the weft is pulled out of the shuttle. Shuttle race: A vertical back plate (30) (Figs. 3 and 4, not shown) guides the shuttle at the moment of picking and has slots (31), (32) to avoid trapping the weft. A plate 35 is also provided to guide the weft. Reference has been directed by the Comptroller to Specification 1,091,314.

Title: Thermostat circuits

Filed: 1973-12-27
Abstract: 1450927 Thermostat circuit SIEMENS AKSJESELSKAP 27 Dec 1973 [29 Dec 1972] 59760/73 Heading H2H A thermostat circuit comprises a temperature sensitive resistor 4 in or in parallel with the igniting circuit of a triac 2, is arranged with other components on a heatsink and is connected so that the currents through the temperature dependent resistor when the triac is on and off cause the circuit to exhibit thermal hysteresis. As shown, 4 is a NTC resistor and is mounted with resistors 5 and 9 on a heatsink. The load 1 is a heating element. Terminals 13 and 16 are supplied with A.C. With the triac off and the NTC resistor hot flow resistance, current flow is via resistors 5, 4, 6 and 8. As the NTC resistor cools, the voltage across it rises until it is sufficient to fire diac 3 and the triac. The current path through 4 now becomes 7, 6, 4, 2 and this current is arranged to be greater than that with the triac off. The triac stays on until the NTC resistor resistance drops sufficiently for the diac to turn off. The 90 degree phase shift introduced by capacitor 7 (which could be replaced by an inductor) minimizes radio interference by firing the triac at the zero crossings. The series circuit of resistor 9 and potentiometer 10 allows variation of the thermostat setting. The circuit may be used in a refrigeration system with a PTC resistor. Several variations including placing the potentiometer 10 in series or parallel with the temperature sensor to control its operating point are described.
