Title: Improvements in or relating to thermionic converters
IPC: H01J45/00
Filed: 1962-10-05
Abstract: 947,281. Thermionic converters. GENERAL DYNAMICS CORPORATION. Oct. 5, 1962 [Oct. 20, 1961], No. 37870/62. Heading H1D In a " plasma thermocouple using e.g. caesium vapour, a further work-functionreducing gas, e.g. hydrogen, is controllably released into the envelope during operation to reduce the anode work-function from about 1.8 volts to 1 volt, i.e. the converter efficiency (expressed as voltage output over ¸ maximum potential level) is increased from about 45% to 70%. As described, the converter operates in a nuclear reactor and comprises a nuclear fuel material/cathode 26 surrounded by an anode container 14 mounted on ceramic insulators 16, 18 and-housed in a nuclear fuel-can 10. The fuel material/cathode may be uranium dioxide encased in an electron emitter such as tantalum, or uranium carbide or a uranium carbide - zirconium carbide mixture which itself acts as the electron emitter, in addition to providing the necessary heat for electron emission. At the base of the converter two reservoirs 44, 46 contain respectively caesium, and a hydrogen releasing material such as zirconium hydride, uranium hydride or calcium hydride. The hydride container 46 is isolated from the converter by a sheet of e.g. palladium or tantalum 54 which -becomes permeable to hydrogen at operating temperature but is opaque to larger molecules, e.g. caesium. The hydrogen concentration is controlled by heating coils 52 surrounding the hydride container 46. The permeable sheet 54 may rely on the converter heat or be provided with heating means 64. Operating figures quoted.-Anode temperature 0-1000 C., e.g. 300 C.; cathode temperature 1000-2000 C.; caesium concentration 10<SP>-6</SP> to about 1 mm. Hg, e.g. 10<SP>-5</SP> mm. Hg; hydrogen concentration to result in back currents of 5 to 15% of the cathode current, e.g. 10%; cathode current 1 amp. per square centimeter.

Title: Process for decreasing the action of transverse currents on an immersed pipe or group of pipes and a device for carrying out said process
IPC: F16L1/16
Filed: 1963-09-26
Abstract: 1,007,996. Supporting pipes. SOC. D' ETUDE DU TRANSPORT ET DE LA VALORISASATION DES GAS NATURELS DU SAHARA S.E.G.N.S. Sept. 26, 1963 Oct. 8, 1962], No. 37898/63. Heading F2P. The action of transverse currents on an immersed pipe or group of pipes is decreased by placing the pipe within a casing of polygonal section. The upper and lower faces of the casing may be put into mutual communication by means of spaced passages 7. The profile of the casing 2 is trapezoidal with its base 4 resting on the sea bed. The base has slight projections 4b, 4c which reduce the tendency of the casing to slide on the sea bed because of transverse currents, e.g. F. Metal lattice strip 6 covers the top part of the casing to give the surface a roughness which creates turbulence that tends to divert upwards the current leaving the surface and so reduce the lowering of pressure on the side of the casing remote from that subject to the currents F. Vents 7 are situated between the two pipes la, 1b, protected by the casing and, by putting the top and bottom surfaces in communication with each other, decrease the pressure gradient between them. Thus the lattice 6 tends to reduce drag and the vents tend to reduce lift.

As shown the bottom 15 of the inner shell acts as a diaphragm and lifts valve member 21 off a valve seat 22 surrounding an aperture 12a in the bottom 8 of the outer shell when the air pressure between the shells increases. The interspace is filled with foam plastics 20 and the two shells are secured together by a snap fit at 14. Wire handles 25 are received in socket members 24 at opposite sides of the dish. The lid of the dish also comprises inner and outer plastics shells 28, 29 connected by a friction fit at 31 and filled with foam plastics. A lug 33 upstanding from the inner shell projects through an opening in the outer shell of sufficient size to constitute a permanent vent, and a knob 34 is screwed on to the lug. As applied to a double-walled plastic tumbler, Fig. 2 (not shown), the valve member 21 seats on the top of a tubular outlet projecting upwardly from the base of the outer shell. The inner shell has a depending peripheral flange at its upper end circumferentially serrated to engage serrations on the upper rim of the outer wall.

Abstract: 346,808. Discharge apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Foulke, T. E. ; 30, Evelyn Place, Nutley, New Jersey, U.S.A.) Dec. 19, 1929, No. 38945. Convention date, Dec. 19, 1928. [Class 39 (i).] In discharge devices operating with a negative glow and used as lamps, as rapidly modulated sources of light or as voltage regulators, two sheetmetal electrodes 9, 10, Figs. 2 and 3, are arranged parallel to the axis of the envelope 1 and are bent so that their longitudinal edges are parallel and separated by small gaps 16, a backing 5 of insulating material for the opposed inner faces of the electrodes being shaped, for example, grooved adjacent to the gaps 16, so that the backing is clear of the gaps. Easy starting and reduced disintegration of the backing results, the attraction of positive ions from the gaps by the backing being reduced by the grooves. The cylindrical backing 5 of lavite, porcelain or glass may be hollow, or may have a recess for the pinch and holes for the leads 6, 7 as in Fig. 3. The leads 6, 7 are welded to transverse ends 91, 101 of the electrodes and disintegration at the gap between these ends is reduced by grooving the backing or by getter material 14 serving also to purify the gas filling. The electrodes may be of 5 mil sheet nickel and the getter 14 of a mixture of magnesium and aluminium or of other metal of lower atomic weight than the electrode or of oxide of such metal. The electrodes may also be of iron, copper, brass, zinc, aluminium, magnesium or calcium. The lower ends of the electrodes have securing tabs 9a and carry internally at diametrically opposite points magnesium, calcium, barium, strontium, lithium, potassium, rubidium, caesium or alloys acting to purify the gas and to reduce the starting and operating voltages. Compounds yielding these metals on heating may be used. A further gas-purifying getter 17 is produced by painting the stem with a mixture of lime, red phosphorus and amyl acetate or water and heating. The envelope is of lead glass, lead borosilicate glass, quartz, &c. and is filled with gas at 30-50 mm., preferably at 36 mm. The gas may be a neonhelium 70-30 mixture and 0À1-2À0 per cent of argon may be added to reduce the starting voltage. The proportion of neon may be reduced to 5 per cent or less to reduce electrode disintegration whilst retaining the neon colour. Fillings of hydrogen or the vapour of mercury, lithium, cadmium, caesium, &c. may also be used. A lamp for operation at 110-220 volts is provided with a resistance 8 in its base.

Liquid is applied to the surface of the drum, and thence to the plants, by a number of rollers 23 &c. mounted between arms 21, 22, pivotally attached to the frame member 2, and resting on, and driven by the drum. Each roller 23 &c. is hollow and provided with a covering of spongy material 41 which absorbs the liquid, which is contained in the rollers, through holes 40 in the roller wall; end wheels 36, 37 on the rollers prevent excessive compression of the spongy material 41. In another embodiment, Fig. 3, the liquid is fed by a wick 55 from a supply 54 to an endless plant-contacting belt around two rollers 51, 52. Alternatively a wick may be used to interact directly with a single applicator drum. The rollers 23 may be suspended from chains 46 when not in use and a gutter may then be positioned under the drum to catch drips therefrom.
