Title: Improvements in electric discharge devices
IPC: H01J17/40
Filed: 1927-03-28
Abstract: 271,419. Raytheon Manufacturing Co., (Assignees of Smith, C. G.). May 24, 1926, [Convention date]. Low - pressure metallic-vapour apparatus. - In a gaseous discharge tube such as a rectifier, having a non-incandescent cathode whose active surface comprises an alkali metal such as caesium, or potassium, or other material with a low work function, the cathode surface is roughened or coated so as to cause the material to adhere, and the anode is arranged to operate at a temperature high enough to drive off material deposited from the cathode, so that the potentiallowering function of the material is confined to the region of the cathode. As shown, the cathode consists of a cylinder 2 having closed ends and of large surface so that a portion only of its interior surface is active at a time, and the discharge shifts continuously over the surface, alkali metal vapour being adsorbed by the inactive portions while being driven off from the portions momentarily active. The surface of the cathode should preferably be rough, and for this purpose flanged rings 12 may be mounted on the cathode. and the cathode may be formed of carbon or of metal coated with carbon; a layer of chromium, or the oxide of an alkaline earth metal may be applied, or a metallic cathode may be oxidized, before coating with the electropositive metal. The reduced ends of the anodes 3 extend inside flanges on the lower ends of the cathode, and the lower parts of the anodes are surrounded by shields 6, the flanges and shields being spaced from the anodes at a distance equal to the mean free path of electrons in the gas. The anodes may be heated independently of the discharge. The bulb 1 is exhausted and caesium vapour and neon admitted. A deposit of caesium in the bulb may be obtained by mounting in a tubular extension of the bulb a metallic capsule 17, Fig. 6, containing caesium chloride and calcium in excess, the ingredients being separated by a wad 18 of steel wool through which they pass when heated by current induced from a winding around the tube. Caesium is' condensed on the bottom of the bulb and the tubular extension is sealed off at 19. Magnesium may be used instead of calcium. In a modification the capsule is mounted inside the cathode and heated by induced current or by a discharge between the cathode and anodes. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of an alkaline earth metal as coating material for the cathode. This subject-matter does not appear in the Specification as accepted.

Title: Hydrodynamic gas bearing
Inventor: SLATTER BRIAN HUDSON
IPC: F16C33/10
Filed: 1961-03-09
Abstract: 927,900. Fluid-bearings. BRISTOL SIDDELEY ENGINES Ltd. Feb. 28, 1962 [March 9, 1961; Sept. 2, 1961], Nos. 8606/61 and 31634/61. Class 12 (1). In an hydrodynamic gas bearing of which the non- rotary one of the two coacting elements includes two complementary part-cylindrical portions with their longitudinal edges spaced apart, one portion supports the load and provides an anchorage for adjustable means acting radially on the other portion to hold it floatingly in a position for causing the rotating rotary element to be urged towards the load-carrying portion so that the gas in the clearance between them is so affected that the onset of half-speed whirl is raised above the maximum operating speed of the bearing. The said one portion may be a stationary tube which at one side has a part-cylindrical portion 10 acting as an hydrodynamic loading pad and an opposite portion 11 for supporting the load, i.e. the rotary shaft 12 (Figs. 1 and 2). The tube may have an opening to accommodate the loading pad 10 floatingly held by a sphere 17 supported from structure radially outside the tube, e.g. a screw 18 in a hole 19. The portion 11 may be supported by a flange 13 from one side of a diaphragm 15, with a clearance opening 22, to the other side of which a ring 16, providing the anchorage for the pad 10, is made coaxially fast, through the sphere 17, a screw 18 (in the hole 19) clamped by a screw 21 in a cheek 20 (Fig. 3). In a modification the positions of the flange 13a and ring 16a are reversed (Figs. 5 and 6), the diaphragm 15a is between the ring 16a and a part ring 25. A clamping plate 24 is held to the ring 16a by screws 29, 31 to hold the screw 18a as adjusted and the hole 19a is formed by the plate 24 and ring 16a. Instead of an opening the stationary tube may have an internal recess on one side associated with a bleed hole. The load-carrying portion 11c may be formed with a window and assembled within a tube 39 (Figs. 9 and 11), located by a dowel 40, the gaps 38 being vertical and parallel (not radial). The tube 39 has a flange 41 to engage a ring 16c to which is held a ring 16cc to clamp the diaphragm 15c therebetween. The pad 10c is adjusted by a screw 18c in a hole 19c in the ring 16c extending through a hole in the tube 39 to engage the pad 10c through the sphere 17c, the rings 16c and 16cc being gapped near the screw 18c, and a slot 16d is in the ring 16c to split the hole 19c so that a screw 42c can be tightened to hold the screw 18c as adjusted. The recess 37a is vented by a bleed hole 35a. In another form (Fig. 12), the rotary cylindrical bore 44 has a stationary hollow shaft 11d extending therethrough and the sphere 17d is adjustable radially of the shaft by a screw 18d threaded in a cross-bar 45 welded to the bore of the load-carrying portion 11d, the loading pad 10d being in an opening 23d therein. Instead of bearing centrally of the arc of the loading pad, the ball may be made to bear on the pad at a distance from the leading edge which is about two-thirds of the arc.

Abstract: 1456308 Switchboard conductor supports WESTINGHOUSE ELECTRIC CORP 27 Feb 1974 [1 March 1973] 8814/74 Heading H1N A switchgear unit, including a bus-bar section and a circuit breaker enclosure, is provided with support blocks for the load-side extensions from the circuit breaker, the blocks and extensions being mutually adapted to obtain a rigid assembly. The load terminals of the circuit breakers are connected to extension conductors 42 each of which comprises a flat strip 52 with a conductor 50 (which in the embodiment is tubular) brazed on to one end and at right-angles to it. These extension conductors are rigidly clamped by a support assembly comprising a mating pair of insulating blocks, each block 48 having laterally extending openings to receive the conductors 50, and associated pockets parallel to the flat mating faces to receive the end of the flat strip portion 52, the assembly being clamped together by a bolt 62 and secured to the frame of the unit by bolts through the slots 58. For circuit interrupters of lower rating with conductors of smaller diameter, clamping is obtained by displacing the blocks of a pair relative to one another so that the holes in one block are off-centre with respect to those of the other.

The outer section 19 of an articulated boom 15, 19 mounted at the rear of a vehicle and carrying a load support 20, is capable of rotation through 360 degrees relative to the inner section 15. A ram 26 is pivotally connected between a pivot 27 on the inner boom section and a pair of links 29, 30. The link 29 is pivotally mounted on the inner section and the link 30 is pivotally mounted in one of four holes in an index plate, Fig. 4 (not shown), secured to the outer section 15 coaxially with the pivotal connection 24 between the sections. The arrangement is such that the ram and linkage can cause rotation of the outer section relative to the inner section through 180 degrees.

Title: Improvements in or relating to the regulating and governing of rotary air motors
IPC: G05D13/00
Filed: 1926-04-06
Abstract: 275,690. Lithgoe, J., and Richardson, D. E. April 6, 1926. Compressed-air engines.-The supply of air or like pressure-fluid to a rotary fluid-pressure motor is regulated by a valve automatically controlled by a rise in pressure of the pressure-fluid in front of the valve to cause a restriction in the fluidsupply passage. The valve is independently operated by a speed governor when a certain speed is exceeded. The pressure in front of the valve acts on an area equivalent to that of the valve spindle c<1> of a hollow cylindrical valve and lifts the valve against a spring c and so reduces the effective area of the port c<2> in the valve. The speed-governor consists of a spring-restrained loaded plunger e mounted in a member d carried on the end of the engine shaft and surrounded bv a ring e<3> which moves to an eccentric position when a certain speed is reached and acts on a lever F connected with the valve so as to move the latter angularly to effect a reduction of the area of the port c<2>. The lever F is formed with a piston f to give a dash-pot effect.
