Title: Compressed-gas circuit interrupters
IPC: H01H33/56
Filed: 1961-07-03
Abstract: 923,075. Gas-blast switches; circuit-breakers. WESTINGHOUSE ELECTRIC CORPORATION. July 3, 1961 [Aug. 17, 1960], No. 23971/61. Class 38 (5). A re-circulating gas-blast switch has a source 18 of high-pressure gas having a higher arcinterrupting ability than air, blast valve means (33... 35) for applying blasts of gas to the switch contacts 11, 12 during an opening operation, and piston means 15 which are supplied with gas from the same source 18 to close the switch contacts. In a multi-pole arrangement, each pole is housed in a separate tank 2 and the poles are controlled by common mechanism in a housing 5. To close the switch, a closing valve 17 is operated to admit gas above the piston 15 which is moved downwardly to close the contacts and to stress an opening spring 70. The piston 15 is held in the closed position by a latch 69 and the compressed gas in the cylinder 16 is dumped through a dumpvalve 16a to a low-pressure reservoir 19. To open the switch, the latch 69 is released and the blast valves 33... 35 are opened to cause, in each pole, gas to flow through a pipe 37, a lift rod guide 39, a lift rod 10, a cross-bar 9 and movable contacts 12 into the arc-extinguishing units 8. The gas discharged into the tank flows through an activated alumina filter 64 and pipe 47 to the low-pressure reservoir 19. A compressor 20 pumps gas from the reservoir 19 to the high-pressure reservoir 8 which may contain sufficient gas for five closing and opening operations. The gas may be sulphur hexafluoride, selenium hexafluoride, a mixture of these gases or a mixture of one of these gases with carbon dioxide, nitrogen, helium, or argon. Heaters may be provided to prevent liquefaction of the gas, and flap valves 45 may be provided in the high-pressure manifold 29.

Filed: 1975-06-04
Abstract: 1507929 Ultrasonic mixing and spraying MITSUBISHI PRECISION CO Ltd 4 June 1975 [4 June 1974] 24087/75 Headings BIC and B2F [Also in Division F4] A device for finely dividing a liquid, for combustion, spray drying or humidifying, comprises a nozzle 124b for passing a high pressure gas G, a sonic generator 170 including a cavity resonator 134 to generate an impulsive sound wave when the gas emerges from the nozzle, and conduit and port means 128, 128a and 130, 130a, for introducing the liquid into the nozzle. The tanks 142, 144, for different liquids are connected to a high pressure tube 122 as well as to nozzle 124b and generator 170 includes an impulse-wave generator 140 having a concave surface 140a. In operation, gas under pressure G flows through nozzle 124b, generator 170 and out through a nozzle 132, so as to vibrate resonator 134 to thus generate an impulsive wave at generator 140. Due to a pressure differential between tube 122 and tanks 142, 144, and a reduced pressure in nozzle 124b, the liquids from the tanks are sucked into the nozzle to be finely divided and mixed with each other and with gas G, and the mixing is further improved due to sound waves at resonator 134. Valves 146, 148 may be adjusted to vary the mixture. A single liquid may be divided and mixed with the gas, or more than two liquids may be used.

Title: Anodes for use in the electrolytic evolution of chlorine
IPC: C25B11/10
Filed: 1960-07-11
Abstract: Anodes made of, or coated with, a platinum group metal are protected from attack in the electrolytic production of chlorine by applying thereto a layer of magnetite.  The magnetite is formed by first applying a layer of iron by electrolysis, sputtering or spraying, or a layer of an iron compound such as the hydroxide, carbonate, or oxalate by chemical or electrophoretic precipitation, spraying, rolling or brushing, and then oxidizing this layer by heating at 600 DEG -900 DEG C. in carbon dioxide, air or water vapour, either under reduced pressure or in admixture with inert gas.  Before and after oxidation, the layer may be heated in an inert amtosphere or in vacuo: in the case of an iron compound the layer is heated before oxidation in a reducing atmosphere, e.g. hydrogen.  Reference is made to platinum-coated titanium anodes.ALSO:Anodes made of, or coated with, a platinum group metal are protected from attack in the electrolytic production of chlorine by applying thereto a layer of magnetite.

Title: Resuscitation apparatus
Inventor: BAILEY RONALD ARTHUR
IPC: A61H31/00
Filed: 1962-06-22
Abstract: 1, 040, 753. Resuscitation massage apparatus. APPLIED CONTROLS Ltd. June 14, 1963 [June 22, 1962], No. 24156/62. Headings A5R and A5T. A cardiac massage device comprises a pressure applicator including a piston and cylinder 6, bellows or capsule (not shown) connected to a source of pressure fluid through a valve 8<SP>1</SP>, the valve being operated under the control of a timing mechanism including interconnected relay valves 11, 12 and associated pilot valves 13, 14, 15 and 16 to cyclically vary the pressure at heartbeat frequency. A pressure pad 7 is reciprocated at heartbeat frequency to repeatedly apply mechanical pressure to the chest to effect massage of the heart. The pad is connected to a piston reciprocated in a cylinder 6 which receives pressure fluid supplied through a main pressure regulator 18, an adjustable secondary pressure regulator 19 and a control valve 8. Each relay valve 11, 12 is controlled by two pilot valves 13, 14, 15, 16 each including a needle valve which determines the frequency of its associated relay valve. A pilot fluid pressure supply to the valves of the timing mechanism is received through the main pressure regulator and a pilot fluid pressure regulator 17. One relay valve 11 is set to operate at heartbeat frequency and the second relay valve 12 operates at respiration frequency. The arrangement of the valves is such that for one half cycle of each cycle of the second relay valve, with the shut-off valve 21 in the pilot fluid supply to the second relay valve open the first relay valve is inoperative to enable the patient to breathe normally and for the other half cycle of the second relay valve the first relay valve operates normally. Thus the pressure pulses applied to the pad 7 are interrupted periodically at respiration frequency. When the shutoff valve 26 is closed both relay valves are inoperative. Supply of gas at respiration frequency to a face mask or intratracheal tube for assisting the breathing of the patient may be derived from a bleed connection in a line between the second relay valve and one of its pilot valves. The components of the device are mounted on a beam 4 (Fig. 1 not shown) adjustably supported over the patient by uprights 2, 3 interconnected by a base plate 1 placed beneath the patient.

Abstract: 749,905. Gripping forks for fork lift trucks. EASTWOODS, Ltd., and PAISLEY, J. Dec. 29, 1953 [Sept. 29, 1952], No. 24383/52. Classes 78 (3) and 78 (4). In a lift truck fork for handling stacked articles, gripping members are extruded from the side faces of the tines by relative movement between the tines and. load plates arranged on the tops thereof. As shown in Fig. 1, the fork comprises an I- beam 12 having a top flange 13 to which the load gripping arms 21 are pivoted. These arms are moved outwardly when the forks are inserted between a bottom layer of bricks by a load-plate 23 engaging the second layer and being displaced thereby. A shank 24 secured to the plate depresses one end of a bell-crank lever 18 which passes through a hole 10 in the web. The arm 19 of the lever presses the associated arm 21 outwards to grip the load. The other arm 21 is extended similarly and a spring 22 restores the arms when the load is removed. In one modification two channelled members comprise the forks and the arm 19 of the bell-crank lever has a horizontal extension passing through one wall of the channel. In another modification, Figs. 4 and 6, the load gripping members 51 are pivoted on a top plate 50 provided with pins 8 which pass through holes in the fork and springs 58. Shafts 60 supported on springs 67 each carry two groups of three bearings 68. When the plate 50 is depressed by engaging the second layer of bricks, plates 59 extending in two groups of three from the load-gripping arms, are engaged by the bearing 68 and rotated outwards until a predetermined pressure is reached when the springs 67 give and the forks and load plate move in unison on further raising the forks.

In a station which includes a loud-speaker, off-normal contacts of an impulse sender put a calling condition on the line. As illustrated, each station of a system is connected to a switchboard where it controls a single wiper selector SEL with hold and stepping relays 311, 312. When the dialling mechanism 13 at station S2<SP>11</SP> is off-normal, contacts 1 energize a relay 14 which locks up over a ringing key 204 and a release key 12. Relay 14 operates relay 15 which locks up to light a lamp 203 and connect earth to wire L of the line over coil 222 to operate hold relay 311 at the switchboard. Impulses from contacts 2 of the dialling mechanism operate relay 312 to step the selector SEL to the wanted station which is called by operating key 204, connecting wire L of the line to earth over a resistor 220 to operate a buzzer, and releasing relay 14 to connect positive potential to amplifiers 211, 218, associated with a loud-speaker and microphone connected to the line over a junction J and capacitor 216. To release the connection the key 12 is moved to its off position to release relay 15, and to release relay 14 if still operated, to disconnect the hold relay 311 at the switchboard which is only released when both stations have cleared. A call received by station S2<SP>11</SP> is announced by buzzer 239 and reply is effected by putting key 12 to the answer position energizing relay 15 to light the lamp 203, disconnect the buzzer and provide power for the amplifiers 211, 218, while connecting junction J to the line. A call to station S2<SP>11</SP> may be taken over by a station S2<SP>1</SP> by operation of a cradle switch 306<SP>1</SP> which diverts the line and operates a relay 208 to release station S2<SP>11</SP>. A call established by station S2<SP>1</SP> may be transferred to S2<SP>11</SP> by restoring cradle switch 306<SP>1</SP> and operating key 12 to the answer position. As a connection is held until both stations have cleared conference connections may be set up by asking a called station to dial to connect with a further station.
