Abstract: 467,045. Registering-mechanism for meters. GLOVER & CO., Ltd., T., WILSON, J. S., and KLEIN, J. F. Feb. 1, 1936, No. 3098. [Class 106 (i)] In a gas meter in addition to the mechanism for registering the total amount of gas passing through the meter, a mechanism is provided for registering the quantity passing during a definite period of time, e.g. during the night. As shown in Figs. 3 and 4, the meter drives a spindle 6 which actuates the usual registering mechanism. On the spindle is mounted a worm 6<a> that gears with a worm wheel 11 loose on a short shaft 9. The worm wheel 11 carries one element 12 of a clutch, the other element 14 of which is formed on a sleeve 13 slidably mounted on the shaft 9 and provided with slots engaging a pin 15 passing through the shaft. To the lower end of the shaft is secured a worm 18 engaging a worm wheel 8 that drives the second registering mechanism. On the sleeve 13 is mounted a ring 16 with a helical spring bearing on the ring and the clutch element 14. The ring 16 is formed with a groove that is engaged by the bifurcated end 21<a> of a bell-crank 21 connected by a link 22 to the operating member 23 of the clock controller 19. The controller is of known construction and as shown in Figs. 6 and 7, comprises a toothed operating member 23 gearing with a wheel 24 carrying a stop pin 24a normally held by a projection 25b on a pivoted trip member 25. An adjustable trip release arm 26 is provided which is arranged to release the trip member 25 at any desired time. On release, the wheel 24 is rotated by the clockwork one revolution to impart a half revolution to the member 23. At the end of the period the parts are again released and the member 23 is restored to normal position. In a modified arrangement shown in Fig. 10, the registering mechanisms are arranged side-by-side, the meter spindle 6 drives the main register 1 and through worm gearing 27 drives a spindle carrying the clutch element 12. The other clutch element 14 is mounted on a shaft 9 which is displaceable by the fork 21a of the clock operated bell-crank. The fork engages a groove in a sleeve 16 with a spring 17 bearing on the sleeve and on a washer 33 on the shaft 9. In the position shown, the clutch is operative to transmit movement to the registering mechanism 30. When the sleeve is displaced to free the clutch it engages a collar 34 on the shaft 9 so as to move the shaft to the right.

IPC: B29D7/00
Filed: 1924-02-11
Abstract: 211,162. Soc. Anon. la Cellophane. Feb. 12, 1923, [Convention date]. Drying materials in long lengths.-A process of drying celluloid and like. films particularly those produced from aqueous solutions of cellulose, consists in passing the films over a series of spaced rolls which serve to support and guide the films without exerting pressure thereon, the amount of shrinkage of the films being predetermined by the spacing of the rolls, which are arranged within a heated chamber and may be heated internally. The film 5, Fig. 1, passes from a roll or direct from the film-producing machine over superposed rolls, which are spaced apart by means of changeable rings 2, 4, Fig. 5, and thence to a rotary receiving roll. The lower rolls are rotated through a pulley drive and countershafts 9 from a shaft 8, each pair of rolls being driven from a single countershaft, and the upper rolls are frictionally driven through the rings from the lower rolls. The pulley belts are adapted to slip to adjust the speed of the lower rolls to compensate for shrinkage of the film. After a part of the film has been wound upon the receiving roll the pulley drive can be disengaged from the lower roll by a clutch. The lower rolls may be heated internally by a fluid introduced through pipes 15 from a main 14.

Title: Improvements in and relating to automatic voltage stabilizing circuits
IPC: G05F3/06
Filed: 1946-02-06
Abstract: 624,423. Automatic voltage regulation. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 6, 1946, No. 3745. Convention date, Feb. 13, 1945. [Class 38 (iv)] A voltage stabilizer comprises an input circuit 1, 1 with a normally unsaturated inductance 5, serially connected therein, a normally saturated inductance 3 with a condenser 4 connected across a winding thereof, and an output circuit 2, 2 which includes a series connected condenser 7 and is connected to have the major part of its voltage supplied by a winding of the normally saturated inductance, the effective reactance of the condenser 7 being small in comparison with the reactance of the series connected inductance 5 under all normal conditions of operation. The volt-ampere value of the series condenser 7 is less than 15 per cent, preferably 12 per cent, of the voltampere value of the series inductance 5 in the input circuit. As shown in Fig. 1, the inductances 5 and 3 each form a separate unit, and an inductive winding 6 of a few reversely wound turns on the unsaturated core of the inductor 5 provides means for compensating the stabilizer for its inherent regulation between zero and full-load unity power factor. The condenser 7 provides compensation for the increased regulation caused by wattless components of load current. The winding of the saturated inductor 3 may be in the form of either a voltage step-up or step-down auto-transformer with tappings to which the junction of windings 5 and 6 may be connected. In a modification, Fig. 4, the stabilizer comprises a single core 15 of the shell type with a centre leg provided with magnetic shunts 16, one portion of the leg which carries a primary winding 17 being of greater cross-section than the portion which carries the secondary winding 18. A condenser 19 is tuned in the neighbourhood of resonance with the secondary winding 18 when normal voltage is applied across the primary winding. The load circuit 2 is connected across a suitable portion of the winding 18 through a compensating winding 20 on the magnetic shunts 16. The series condenser 7 is connected in the load circuit by way of a series transformer 21.
