Patent GB-1074788-A (GB)
Title: Method of and apparatus for repairing thread breakage in a spinning machine
IPC: D01H4/50
Filed: 1965-04-15
Abstract: In spindle-less spinning when the spun yarn is conducted from a rotating spinning-chamber by a tube, a break occuring in the yarn is detected, and the return of an end for piecing is initiated, while the yarn is still in the tube.  The fibres are delivered into the chamber (1), in which sub-atmospheric pressure is generated by channels in its cover, by rollers (6) driven by a motor (7) through a tube (4a); the spun yarn is drawn out of the chamber through a tube (9) by rollers (12) and is taken up on a drum-wound package (27), the rollers and the drum being also driven at related speeds by motor (7).  In the tube (9) is a detector (10); when the yarn breaks, the detector closes contacts to energize a reversing-clutch (17) whereby the direction of rotation of the drum and the rollers (12) is reversed to feed back into the tube a length of yarn determined by an adjustable rotating cam (24).  The contacts also move the tube (4a) so that the fibres are delivered to another tube (4b) which directs them outside the spinning chamber.

Title: Improvements relating to Steam Heating Systems for use with Railway and like Vehicles.
Inventor: CHEVILLOT ALFRED
IPC: B61D27/00
Filed: 1918-10-11
Abstract: 129,180. Chevillot, A. Oct. 11, 1918. Heating by circulation of fluids.-Relates to steam heating systems for railway and like vehicles of the type in which an injector nozzle is arranged to circulate any uncondensed steam from the heaters through the system again. According to the invention, each injector nozzle 12, Fig. 3, is located in a connexion 13 leading between the steam distributing pipe 5 and a pipe 9 leading to each radiator or heater 10, Fig. 2, and the exhaust outlet pipe 11 is arranged adjacent to the nozzle 12 in such a way that the uncondensed steam is projected again into the pipe 9, while the water of condensation escapes to the atmosphere. The arrangement shown comprises a union 14 at. tached to the connexion 13 and projecting into the open end of the pipe 11. In addition to the distributing pipes 5 for each carriage, a main steam pipe 1 is provided extending the entire length of the train, and both pipes are mounted on a common support of which the connexion 13 forms a part. By this arrangement, heat is readily conducted from the pipe 1 through the support to the injector nozzle, pipe 5 and outlet 11, thus preventing freezing of the system, the transfer of heat being facilitated by the provision of a chamber 16 in the support 13 in free communication with the pipe 1. Reducing valves 7 may be arranged in the branches between the main steam pipe 1 and the pipes 5 so that a uniform pressure may be obtained in all the pipes 5.

Title: Improvements in radio transmitting receiving system

Abstract: 613,217. Combined radio transmitting and receiving systems; valve modulating circuits. DEHN, S. G. (Collins Radio Co.). June 6, 1946, No. 17231. [Class 40 (v)] A combined transmitter and receiver has a common oscillator whose frequency, when used for reception, can be displaced from the transmission carrier frequency by an amount equal to the I.F. of the receiver. With the ganged switches A<1>, B<1>, C<1> in the " transmit " position, shown in dotted lines, the fixed capacitor 13 is connected across the variable tuned circuit of the oscillator A, whose output passes to the multiplier B, modulated power amplifier C, and through a filter circuit D to the antenna. On switching to " receive," shown in full lines, the condenser 13 is disconnected from the oscillator and the resultant oscillations at a displaced frequency are passed via the multiplier B to a tuned filter circuit F, which passes only the displaced frequency to the mixer H of the superhet receiver shown as G, H, J, K and L. The difference between the previously transmitted frequency and the now displaced frequency is arranged to be equal to the I.F, of the receiver, so that for any given setting of the tuning controls, transmission and reception are effected on the same frequency. The output of the modulator stage E is applied from separate circuits to both the anodes and the screens of the parallel-connected power amplifier valves, Figs. 2a, 2b (not shown).
