Title: Improvements in lighting fittings
IPC: F21V17/00
Filed: 1926-03-31
Abstract: 256,528. General Electric Co., Ltd., and Randall, E. L. March 31, 1926. Globe holders; securing globes to holders.-In an electric or other lighting fitting a support for a glass globe or the like is connected by flexible means to a rotatable member adapted to be turned to coil and uncoil the flexible means so as to raise and lower the globe for cleaning and inspection, a frictional or positive locking device being provided to secure the globe in the raised position. In the form shown in Fig. 1, a globe 1 is removably supported by a ring 2 having lugs 15 provided with holes 14 engaged by caps 16 on the lower ends of two flexible plaited copper suspension wires 3. These wires pass through guide eyelets 21 in a canopy 9 which is carried by a twoarmed spider 10 screwed on to a central spindle 5 which is carried by means of a ring 4 and a locking screw 6. The upper ends of the wires are secured in brass tubes 13 fastened to the upper part of a drum 7 which may be rigidly attached to a cover 8 which is rotatable relative to the canopy 9. This cover 8, together with the drum 7, may be rotatable on the spindle 5 and be secured in position by being clamped against a sleeve 12 by means of a locking nut 11, or it may be rigidly fastened to the spindle and the canopy 9 made rotatable. Alternatively the drum may be connected at or near the top of the canopy in which case the wires 3 pass through a portion of the canopy and are secured to the cover. Ventilation is obtained by means of a space 23 between the cover 8 and the canopy 9 and the spindle may be made hollow to take the conducting wires. The wires 3 mav be in the form of a single length of wire having its centre portion fastened to the drum. In the form shown in Fig. 2, the cover 8 is clamped between the ring 4 and a three-armed spider 17 carrying the canopy 9 which has a downwardly projecting flange 18 and a hoop 19 between which is rotatably mounted a lip 20. The guide eyelets 21 are formed in the lip 20 and the tubes 13 are fastened to the lower end of the canopy so that the wires may be wound on to the lip, the lip being secured in position relative to the canopy by a clamping screw 22. Alternatively the wires may be arranged to pass through the canopy and be fastened to the lip. The ring 2 may comprise two parts 24, 25, Fig. 3, hinged at 26 and fastened together bv a screw 28 passing though the part' 24 and a lug 29 on the part 25.

Title: Apparatus for the storage and distribution of carbon-bisulphide and other liquids
IPC: C01B31/26
Filed: 1946-03-21
Abstract: 621,127. Forcing liquids by liquid pressure. BYWATER, D. March 21, 1946, No. 8817. [Class 102(ii)] Apparatus for storing and dispensing carbon bisulphide or other liquid heavier than water comprises a tank 1 in which the carbon bisulphide 2 is stored beneath water 3 which is connected to a pipe 9 and static head tank 8. The carbon bisulphide is discharged through the pipe 6 and the pipes 6 and 9 are fitted with float valves 11, 12 respectively that float in water and sink in carbon bisulphide and prevent carbon bisulphide and water entering the pipes 9 and 6 respectively. Carbon bisulphide is forced into the tank 1 through a pipe 18 from a container that is connected with the pipe 9 through a pipe 21 and valve 17. The connection between the pipe 9 and the tank 1 is closed by a valve 10 and the water in tank 1 is connected to drain by a valve 26 so that water admitted to the container forces carbon bisulphide into the tank 1 through pipe 18. The tank is fitted with a float indicator 16 and an indicator 27 is fitted to the pipe 18 to indicate whether water or carbon bisulphide is entering the tank 1. Specification 518,346 is referred to.

Title: Improvements in or relating to Internal Combustion Engines.
Inventor: HENRI JEAN BERRUET
IPC: F02G5/04
Filed: 1919-04-08
Abstract: 125,395. Berruet, H. J. April 9, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Motor power plant. - Steam generated in the water jacket 3 of an internal-combustion engine 1 is dried and superheated by the exhaust gases of the engine and used in a steamengine 11 or turbine. Heat is also transfsrred from the piston through an oil reservoir 25 to water circulated through coils 24 and supplied to the said jacket 3. Steam from the jacket 3 passes by way of a collector 4 surrounding the exhaust pipe 5 for the exhaust gases to a dome 6 and port 7 leading to a pipe 8 arranged coaxially within the exhaust pipe 5. Hence the superheated steam is led through a pipe 9 to the jacket 10 and valve 12 of the steam-engine 11, which discharges through a pipe 15 to a condenser 16 and radiator 17. The condensed water is returned partly to the condenser 16 and partly through a pipe 19 and floatoperated valve 20 to a reservoir 22, whence it is circulated by a pump 23 through the heating coils 24. A circulating pump 26 forces oil from the reservoir 25 through a pipe 27 into the piston of the internal-combustion engine. Water from the reservoir 22 is supplied to the jacket 3 according to requirements by a feed pump 28 driven by a donkey engine 29, the supply of steam to which is controlled by a float 32 positioned by the level of the circulating water. In a modification, the steam is arranged to expand on the other side of the piston of the internal-combustion engine, and water is conveyed from the reservoir 22 to the jacket 3 by an injector supplied with steam from the pipe 30. Where the steam-engine is a turbine, the fly-wheel of the internal-combustion engine may constitute the rotor of the turbine.

Title: Improvements in and relating to submarine mines
IPC: F42B22/18
Filed: 1916-06-24
Abstract: 160,181. Skipwith, H. L. d'E., and Sturgeon, R. A. June 24, 1916. Mines,marine. - Relates to mines of the kind in which the mine body is released from its anchor after sinking with it to the bottom, and is subsequently stopped at a given depth by means of a hydrostat which releases a short slack length of mooring-rope, whereupon the change or changes of tension in the mooring-rope cause the mooring-rope drum in the anchor to become locked. According to the invention, the hydrostat is arranged outside the mine and is released therefrom when the locking operation is performed. As shown in Fig. 2, there is a slack length 1<2> of mooring-rope adjacent to the mine 3, the end 13 of the rope being fixed to the mine or provided with a stop which prevents its escape through an eye 11 on the mine. The hydrostat 10 is carried by a pair of tongs 5, 7 which holds the mooring-rope 1 to one eye 8 on the mine. At the appointed depth, the stem 9 of the hydrostat trips a locking catch 6 and falls off with the tongs 5, 7. In one arrangement, Figs. 3 and 4, the sudden release of tension in the mooring-rope 1 allows the mooring-drum carried by a lever 16 in the anchor 13 to fall on a stop 22 which locks the ratchet-wheel 14 of the drum; unlocking, when the tension is restored, is prevented by spring arms 18 which move out of recesses in a plunger 17 at the end of the lever 16. The spring arms 18 are locked before the launching operation by a collar 21 which is displaced out of action to the position shown in dotted lines in Fig. 4 when the mooring-rope is tensioned and lifts the drum and lever 16 at the beginning of the mooring operation. In a modification, it is the sudden excess of tension that occurs when the slack of the mooring-rope is taken up that overcomes a spring in the anchor and locks the drum, a spring stop again preventing subsequent unlocking.

Abstract: 433,164. Valve circuits for wireless reception. COLE, Ltd., E. K., Priory Crescent, Southend-on-Sea, and MARTIN, A. W., 1, Thames Close, Leigh-on-Sea. March 23, 1934, No. 9106. [Class 40 (v)] In a receiver in which a carrier frequency valve feeds a demodulator which is rendered inoperative for signals of below a predetermined amplitude by a potential derived from a subsequent low frequency amplifier whose impedance is dependant on a signal-supplied muting diode, voltage for A.V.C. is derived from the cathode circuit of said carrier frequency valve. As shown the carrier frequency amplifier V1 feeds a demodulator diode V2, the low frequency output of which is fed from its load resistance 7 through condenser 27 to a low frequency amplifier V3. The cathode resistance 26 of the valve V3 is included in the circuit of the diode V2 and the potential thereacross disables the demodulator until the grid bias of valve V3 is rendered more than a predetermined amount negative by the rectified output in the load resistance 23 of an auxiliary diode rectifier V5 fed from a sharply tuned circuit 21, 22 coupled to the anode circuit 3 ... 6 of the valve V1. The diode V4 provides A.V.C. potentials for the valve V1 in known manner, amplified control potentials for previous valves being derived from the cathode resistance of the latter.
