Title: Improvements relating to high pressure electric lamps
Inventor: BEESON ERIC JOHN GEORGE
IPC: F21V15/00
Filed: 1955-07-12
Abstract: 793,636. Housings for high-pressure electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. July 11, 1956 [July 12, 1955], No. 20180/55. Class 75(4) An electric lamp containing a gas at above atmospheric pressure is mounted in a container having means for connecting the lamp to the electric supply and one or more apertures for emission of light covered by shutters when the lamp is not in use. In a lamp comprising a glass or quartz bulb with electrodes a few millimeters apart and having a filling of e.g. Xenon at 3 or more atmospheres for use with an optical system, the container 1 has two relatively small opposed apertures 2 and is covered by a sliding casing 3 which supports an insulating member 5 bearing a metal plate 9 engaging contacts 10 connected to the contact pins for the lamp so that current cannot flow to the lamp until the cover is raised. To prevent the cover being raised until the electric supply is switched on, the container may carry a pin in locking engagement with the casing and connected to a plunger working in a solenoid so as to withdraw the pin against the action of a spring when the current is switched on.

Abstract: 1,184,544. Hydraulic reciprocating motors. MOLINS MACHINE CO. Ltd. May 3, 1967 [May 6, 1966], No.20186/66. Heading F1A. In a hydraulic servomotor system comprising a radial ball piston motor, Fig. 3, controlled by a slide valve 1, Fig. 1, a hydrostatic bearing is formed between the rotating cylinder block 103 of the motor and the stationary pintle valve 115 by grooves 118, 119, 120, 121 in the pintle valve, which are connected to the high-pressure liquid supply line 15 of the motor upstream of the control valve 1. The motor ball pistons 104 engage an eccentric groove 102 in the motor casing, drive being transmitted through a shaft 107 on the cylinder block. Vent holes 105, 106 are formed in the cylinder block, holes 105 registering with grooves 122, 123 in the pintle. Distributing ports 124, (125, Fig. 4, not shown), in the pintle communicate via connections 112, 114 with ports 3 and 5 in control valve 1, Fig. 1. Movement of control valve spool 16 in either direction causes corresponding movement of the motor output shaft, downward movement of the valve spool acting to reduce the pressure at port 3 and increase the pressure at port 5 from the supply pressure at port 4. Exhaust liquid from the motor passes through valve port 2 when the valve spool is moved downwardly, and port 6 when moved upwardly. Hydrostatic bearing grooves 118, 119, 120, 121 comprise three segmental portions on either side of distributing ports 124, (125), each portion being connected through a passage in the pintle to connection 113 and highpressure line 15. The motor casing is vented through connection 111.

A device for detecting failure in the supply of oil-mist to points of application in a lubricating system comprises an expansion or condensing chamber 5 (the only Figure, not shown) for oil-mist passing through a pipe 3 and a nozzle 4, a chamber 9 into which oil-condensate drains from the chamber 5 through a conduit 8, a float 2, a switch 12 actuated by a permanent magnet 10 on said float, and an outlet channel 6 for air separated from the oil-mist in the chamber 5.

Abstract: 814,188. Valves. BRITISH OXYGEN CO. Ltd. July 2,1957 [July 9, 1956], No. 21217/56. Class 135. A valve assembly comprises a pair of valves 11, 12 each adapted to be actuated by plungers 14, 16 respectively, through a common operating lever 18 by means of an operating member 24 resiliently mounted on the lever 18 and having limited floating action relative to the lever, such that movement of the lever towards the valves causes the arm 25 of the operating member 24 to depress the plunger 14 to actuate the valve 11, while continued movement of the lever 18 causes the operating member 24 to float relative to the lever about the top of the plunger 14 so that the arm 26 of the operating member depresses the plunger 16 to actuate the valve 12. The operating member 24 is clamped to the lever 18 by a split collar 21 and torsional movement is provided by a sleeve 23 of rubber or like material. Alternatively, the sleeve may be replaced by a suitable spring. The lever 18 may be formed to support an oxyfuel gas blowpipe, such that the weight of the blowpipe will depress the lever to close the valves in sequence, the valve which is closed first being the fuel gas supply control valve while the other valve is the oxygen supply control valve.

Abstract: 181,265. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Aug. 11, 1921. Automatic starters. - In motor-starters of the sequentially-acting electromagnetic contactor type, the current limit and time-limit intervals between successive contactors are controlled by one or more automatic relays 5, 6, 7 permanently biassed to their operative positions and each having a winding 11 connected to the motor circuit and a short-circuited winding 13 mounted on a separate limb of the magnetic core and inductively related to the winding 11. During the period of rising current immediately after closing a main switch 1, the induced effect in the shortcircuited winding increases the force with which the core holds up a contact-carrying armature 9 and thus virtually adds a time-limit delay to the winding 11. The fall of the armature brings the winding of the next contactor into circuit, and the action is repeated to the end of the sequence. In a modification, a single time and current limit relay controls all the contactors of a group.

Abstract: 781,818. Mixing fluids in flow. BURLAGE, K. M. July 25, 1955, No. 21427/55. Class 86  In apparatus for mixing various grades of oil, disposed in containers 9, 10, with petrol, disposed in a container 13, the containers are connected by conduits 4, 5 and 6 to a distributer 3 disposed at the -top of a mixing 'chamber 1. Each oil conduit 4, 5 is closed by a manually operable stop valve, 19, 20 and a valve 61 controls the supply of petrol through the conduit 6 connecting tank 13 with the mixing chamber 1. The position of a piston 2 in the cylinder 1 determines the quantity of oil to be mixed, this quantity being varied by a control device comprising a cylinder 21 having an inclined slot 18 which is engaged by a pin 53 on the end of the piston rod 17. The cylinder 21 also carries a cam 22 which operates on a rod 23 and lever 24 for opening the petrol supply valve 61. A scale is associated with the cylinder 21. After a predetermined quantity of oil has been admitted to the measuring chamber 1, the cylinder 21 is rotated with the aid of a handle 54, causing the piston 2 to descend and uncover ports 15, 16 connecting the cylinder 1 with a collecting chamber 14. The rotation also causes the cam 22 to actuate the petrol supply valve 61 whereby the chambers 1 and 14 are filled to the desired amount. The lower end of the rod 23 is hinged to allow it to pass over the cam 22 when the cylinder 21 is returned to its original position. The mixture is discharged through a valve 63 in the bottom of the chamber 14, the valve being operated by a bowden cable 65, 66, the sheath 65 of which is attached at one end to a tube 67 and the outer end of the wire 66 is attached to a spring pressed flanged member 68. -When the member 68 is pressed, for example on to a petrol tank, relative movement between it and the tube 67 causes the Bowden cable to open the valve 63. Each holder for the oil cans 9, 10 comprises a knife-like rim 45, 46, for cutting open the bottom of the can, and a needle like projection 51 attached to toggle mechanism 48, 49, 50 for piercing the lid of the can for the supply of air.
