Abstract: 417,036. Valve generating and amplifying circuits. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. April 18, 1934, No. 11695. Convention date, April 18, 1933. [Class 40 (v).] In a valve circuit of the kind in which the cathode is heated by alternating current but is not grounded as regards the signal or operating frequency, means are provided in the primary and secondary circuits of the heating transformer for preventing variations in the transformer constants from affecting the operation of the circuit. As shown, an oscillation generator comprises a tetrode valve 1 with inner and outer grids 4, 3 and cathode connected to a tuned circuit 5 to set up oscillation therein. The anode 2 is coupled to the load or output circuit. The outer grid 3 is grounded at 8 as regards the operating frequency, and the cathode is oscillatory. Condensers 10 are connected across the cathode and the two halves of the secondary coil of the supply transformer 12, a condenser 19 across the primary of the transformer, and condensers 20, 21 between each end of the primary coil and the adjacent end of the secondary coil. All these elements are at oscillatory voltage, whilst the supply source 11 is grounded by two condensers 26 and is isolated from the rest of the circuit by chokes 22. These need only be of small current-carrying capacity as they are on the high-voltage side of the transformer 12. Thermostatic arrangements 24, 25 may be provided in association with the casing 23. In a modification (Fig. 2, not shown), a triode oscillating valve is employed.

Abstract: 864,013. Stuffing-boxes. BROWN FINTUBE CO. April 14,1958, No. 11770/58. Class 122 (5). [Also in Group XXVIII] A rubber-like sealing-ring 28, Fig. 1, is radially expanded by a gland nut 29 into sealing engagement with concentric tubes 10, 11, the side of the ring away from the gland nut being provided with means 38, Figs. 2, 3, forming fluid passages permitting pressure fluid from the space 14 to exert pressure over the whole of said side of the ring. The sealing-ring 28, which is substantially round in cross-section and has a serrated flange 38 extending axially is engaged in a groove 27, formed between a bushing 20 fixed to the inner tube and the end face of a nut 29, which is in threaded engagement with the bushing. After radial expansion of sealing-ring 28, the nut 29 may be locked by a screw 36 and fluid-pressure can, because of the serrations, be applied to the entire serrated side of the sealing-ring 28 to increase the sealing pressure. The sealing-rings may have serrations of rectangular or U-shape, formed in the high-pressure face. In a further embodiment, Fig. 12, the groove may be formed in the inner surface of an extension 54 of the shell tube 10, the ring 63 being radially expanded by a nut 59.

Title: Improvements in or relating to Electric Transformers.
IPC: H01F27/40
Filed: 1916-08-19
Abstract: 108,727. British Electric Transformer Co., and Mount, S. C. Aug. 19, 1916. Transformers.-In transformers, particularly for use with welding-apparatus and furnaces, the secondary coils are connected to concentric terminals h, i, the inner terminal projecting beyond the outer at both ends. When used with oilcooled transformers, the tubes are perforated to permit a flow of the oil; or tubes slit along their length may be used. The tubes are spaced by suitable insulating-blocks, which also are perforated. The circulation of the oil may be made to take place along the tube in two parts by dividing the oil spaces by insulating-stops h<1>, Fig. 5. The upper parts of the terminals are cooled by air circulating through them. The device may be used with aircooled transformers.

Title: Improvements in or relating to controlling arrangements for motor vehicles
IPC: B60K23/00
Filed: 1947-05-02
Abstract: 630,516. Propelling ships. STANLEY ENGINEERING CO., Ltd., HEWSON, R. P., and REARDON, J. C. May 2, 1947, No. 11834. [Class 114] [Also in Group XXXI] In a motor vehicle having a hydraulic transmission from an internal-combustion engine, the driver operates a cam mechanism so that rotation of the mechanism in one direction controls forward speeds while rotation in the other direction controls power braking and reverse speeds. The invention may be applied to invalid tricycles as shown, or to motor boats, where a hydraulic transmission is employed. In the example shown, the steering tiller 2 of the invalid tricycle has the control mechanism housed in a casing 1 pivoted at 3 to an.upright support 4 which is rotatably mounted on an upright frame-piece 5, thus enabling the steering tiller to be swung in both vertical and horizontal planes. Pivoted within the casing are sprung levers 6, 7 which control the engine throttle and the oil flow of the hydraulic transmission through cables 15, 16. The end portions of the levers 6, 7 have rollers 17, 18 which are contacted by a cam 8 which is mounted on the tiller 2, so that rotation of the tiller in one direction controls progressively forward speeds and in the other direction power-braking, 7, reverse speeds. Horizontal swinging of the tiller 2 effects steering control and downward swinging about the pivot 3 effects application of a suitable brake through a control wire 20, and the tiller can be locked in position by a spring-loaded pawl 21 engaging a ratchet 23, the pawl 22 being controlled by a lever 24 disposed within a handle 11 on the steering tiller. In a modification, when the invention is applied to motor vehicles having other forms of steering control, the throttle and oil flow of the hydraulic transmission are controlled through the levers and cam being actuated by an elongated pedal disposed transversely in the vehicle pivoted in the centre and spring-loaded at either end so that depression of the pedal in one direction provides forward speeds and in the other direction power-braking and reverse speeds. Alternatively, the actuating means for controlling the levers may be mounted on the dashboard of the vehicle or in any other suitable position.

Endwise movement of the locking sleeve in one direction is prevented by a ring 19 disposed in a groove 18 and in the other direction by a lip 16 on the coupling head ; the end of the sleeve is bevelled for engagement with the lip 16 and the bevelled portion serves to limit radial movement of the balls when the sleeve is in its retracted position. Fluidtightness between the parts is secured by a washer 15, and the nipple inlet may be provided with a spring-pressed check valve 8. The invention is applicable also to hose connections, draw-bar couplings, &c.

In modifications the supports 4a, 4b, 4c and secondary shafts 7a, 7b, 7c are carried on a two-piece support journalled on anti-friction bearings about the main axis of the transmission, the springs 13 act on the rings 10 through a cupshaped member, and the ratio control mechanism comprises a spiral slot face cam disc. The stationary member 1 may be replaced by a spring-loaded member to render the transmission ratio responsive to the resisting torque. Reference has been directed, by the Comptroller to Specification 713,820.

Projectiles; projectile fuses.-Relates to projectiles containing propellant cartridges in recesses in their bases, as described in Specification 12478/15 [Class 92 (i), Ordnance &c. mountings], and consists in means for ensuring tnat the fragments of the cartridge shall leave the gun with the projectile. In the form shown in Fig. 1, the base c of the cartridge a is of substantial thickness and is connected by a core or webs e to a shoulder f, which is retained in the projectile b by a ring g when the propellant cartridge is fired. In the form shown in Fig. 3, the base c is connected by wire loops It, i to a disk j, which is normally held in the projectile by friction, but is bent to the dotted-line position by the pressure of the gases of explosion of the propellant cartridge; this pressure holds the cartridge parts to the projectile until they have left the gun, whereupon air resistance makes the cartridge parts fall behind. The rear face of the base c is made with annular grooves to prevent adhesion of the base to the standing breech of the gun. The disk y may be made to ignite a time-fuse for the projectile when bent out by the pressure of the propellant gases.
