Abstract: 1,181,220. Separating gases by diffusion. ATLANTIC RICHFIELD CO. 31 Jan., 1967 [16 Feb., 1966], No. 4763/67. Heading B1L. [Also in Divisions H1 and C7] A fuel cell anode 1 comprises an electrically conductive porous substrate 2, with pores with an average diameter of 10 microns or less, and a non-porous membrane 4, of a metal through which hydrogen can selectively diffuse, from 1000Š to 5000Š thick. Hydrogen produced by, e.g. a steam-methane reaction on the uncoated side of the substrate, passes through the membrane to an electrolyte which may be molten sodium hydroxide. The substrate 2 may be of carbon, nickel, iron or copper and the membrane 4 of palladium, palladium silver alloy, vanadium, iron or nickel. Preferably the membrane 4 is produced by vapour deposition of the metal onto substrate 2. Palladium-silver alloys used contain 20% to 40% by weight of silver. Evaporation may be brought about with an electron beam or with a hot filament of, for example tungsten wire.

Title: Improvements in piston sealing rings, piston assemblies, and hydraulic devices incorporating such assemblies
IPC: F04B1/14
Filed: 1957-02-12
Abstract: 861,876. Liquid-pressure engines. WAHLMARK, G. A. Feb. 12, 1957 [May 9, 1956], No. 4776/57. Class 69 (2). [Also in Groups XXVI and XXVIII] In a swash-plate type liquid-pressure engine 20, Fig. 1, the pistons 54 are each provided with a sealing ring 74 (see Group XXVI) which has a spherical outer rim surface whose spherical diameter is substantially equal to the external diameter of the ring. The pistons are mounted in cylinders 41 provided in a.cylinder block 33 which is rotated by a shaft 48 connected by splines 51 and 47, 47a with a driving sleeve 40 and the cylinder block. The swash-plate 32 is rotated by splines 39 engaging with a universal joint 38 mounted in a piston socket ring 35 carried in a non-rotatable control ring 34 ; the control ring may be pivotally moved to vary the piston stroke. The swash-plate ends of the pistons are provided with ball ends 55 having a primary ball segment 78, Fig. 3, of the same effective diameter as the cylinder so that when the working fluid is transmitted through a bore 80 in the piston-rod to act upon the spherical surface, a pressure balance is obtained. The spherical surface is maintained in contact with the socket 59 by a member 59a engaging with a smaller ball segment 78a. A groove 78b separates the two segments and, together with the clearance between the ball segment 78a, and the socket, forms a lubricant reservoir. In a modification, each piston may comprise two piston-rods, one within another, each provided with a head and sealing ring arrangement as shown in Fig. 2 (Fig. 12, not shown). The pump may also be of the type as shown in Fig. 13, in which the cylinder block 181 is stationary and the pistons are reciprocated by the rotary swash-plate assembly 182 ; alternatively, the swash-plate assembly may be fixed and the cylinder block rotated. A valve plate 196 is attached to an eccentric end 197 of the driving shaft 195 and opens or closes inlet ports 201, outlet ports 199 being provided in the plate for co-operation with a central outlet port 202.

Title: Apparatus for compensating for variations in gas pressure in the space above the liquid in an expandion tank
IPC: B65D90/44
Filed: 1968-01-30
Abstract: 1,200,692. Pressure compensating system. COMPAGNIE GENERALE D'ELECTRICITE. Jan.30, 1968 [Feb.21, 1967], No.4834/68. Heading F1P. Variations in the volume of a dielectric liquid, such as oil, contained in a vessel 1 and surroundi an apparatus 2, such as an electrical cable, which apparatus is subject to thermal and hence volumetric changes, are compensated for by the provision of a buffer tank 3 which is connected to a cylinder 6 of pressurized inert gas. Upon the oil in the vessel 1 being displaced into the tank 3, the consequent pressure rise of the inert gas in the tank actuates a pressure contact 7 which in turn actuates a sealed motor compressor unit 4 as a result of which, the excess pressure in the tank is relieved with the gas so displaced being compressed and returned to the cylinder 6. Conversely, in the event of oil being returned to the vessel 1 from tank 3, the consequent decreased gas pressure within the tank 3 de-activates the pressure contact 7 and hence the compressor, and opens an expansion valve 5 so permitting gas to flow from the cylinder 6, via the valve 5, to the tank 3. In an alternative arrangement, the connection between the tank 3 and cylinder 6 is effected by means of a capillary tube and the compressor is rotated at a constant speed, the gas pressure within the tank determining whether the resultant flow is from or to the cylinder 6.

Title: Improvements in or relating to electron discharge devices for the production of trapezoidal or saw tooth potential variations
IPC: H01J43/02
Filed: 1941-06-13
Abstract: 553,403. Cathode-ray tubes. INTERNATIONAL TELEVISION CORPORATION, Ltd., NAGY, P., and GODDARD, M. J. June 13, 1941, No. 5234/43. Divided out of 553,370. [Class 39 (i)] A beam deflection valve for the production of trapezoidal or saw-toothed potential variations, compries two output electrode systems X, Y, X1, Y1, which have a secondary electron emission co-efficient greater than unity. Coacting with these electrodes are collecting electrodes E, E1 and a suppressor grid S. The capacity CO in which a varying potential difference is built up about a fixed mean potential, as for example the deflection plates in a cathode-ray tube for line scanning, is connected between the electrodes X, Y1. As the strip beam from the cathode C, and first and second anodes A1, A2 is deflected across the electrodes by the signals applied electromagnetically or electrostatically between the plates PI, P2, the electrode X becomes progressively negatively charged by the beam as secondary emission is suppressed by the grid S, while Y1 becomes positively charged by secondary emission which is collected by the collector E1. At the end of a line, the beam impinges on the part Y of the electrode XY which is then discharged by secondary emission which is collected by the electrode E, while Y1 is discharged by secondary emission from X1, the grid S1 preventing the secondary emission from reaching the electrodes E1, E. The degree of charging the electrodes is varied by shifting the position of the beam by suitable potentials applied to pairs of plates P3, P4, P5. In a modification for line and frame scanning, Fig. 2, two similar electrodes XL, YL and XF, YF with suppressor grids SL, SF and a common collector electrode E are used, and are displaced laterally relatively to the path of the beam. An auxiliary electrode Q is connected to the plate P3 through a resistance R3. The parts XL, XF produce the line and frame scanning potentials. During each line synchronizing pulse, the electron beam is deflected to fall on the positive charging electrode XL producing the fly-back of the line deflection, but the deflection necessary to reach the YF is produced only by the longer frame synchronizing pulses. The rate of charging XF is slower than that of XL, and is effected by making the area in contact with the beam less or the capacity C.O.F. greater than C.O.L. Specification 553,370 is referred to.

Title: Improvements in and relating to a damping device for a suspension and suspension incorporating this device
IPC: F16F7/08
Filed: 1955-02-22
Abstract: 771,392. Frictional vibration-dampers. USINES DES RESSORTS DU NORD. Feb. 22. 1955 [Feb. 26, 1954], No. 5293/55. Class 108(3). In a damping device for a spring suspension connecting two members b, c, in which two friction elements d and e<SP>1</SP>, e2 are applied against one another by a pressure-applying device f. the element d being unitary with the.member b and the element el, e<SP>2</SP>, and device f being supported between the members b, c, by two opposed springs g<SP>1</SP>, g2, the device f is indeformable on compression of the suspension and does not engage any surface unitary with the member c. In the construction shown in Fig. 2, a main suspension spring a is disposed between the members d, c. The friction element d is in the form of a sleeve rigid with the member c. The element el, e2 is in the form of two separate rings, each of which is radially split into three segments so as to be contractible. In operation, on deflection of the member b relative to the member c, pressure applied to the rings e<SP>1</SP>, e2, f, causes the rings e<SP>1</SP>, e<SP>2</SP> to be contracted into engagement with the sleeve d. In a modification, Fig. 6 (not shown), the springs g<SP>1</SP>, g2, and the rings e<SP>1</SP>, e<SP>2</SP>, f, are disposed within the interior of the sleeve d. There may be one friction ring e, and two pressure applying rings f<SP>1</SP>, f<SP>2</SP>, Fig. 7 (not shown). Instead of the sleeve d being unitary with the member b, it may be held rigid therewith by the action of the spring a, Fig. 8 (not shown). The sleeve d may be replaced by spaced flat plates the rings being superseded by wedge-shaped elements. In a diagrammatic illustration of the principle of the invention, Fig. 1 (not shown), the friction rings e are replaced by flat plates which are adapted to be outwardly urged by the action of a parallelogram linkage connected to the springs g<SP>1</SP>, g2. The length and/or stiffness of the springs g<SP>1</SP>, g<SP>2</SP> may be different. Springs g<SP>1</SP>, g2, may alternatively be of rubber. The length of the springs a may be different from the combined length of the springs g<SP>1</SP>, g2. The working surfaces of the friction members d, e<SP>1</SP>, e<SP>2</SP>, may be provided with a layer of bronze or steel. The apex angles of the rings e<SP>1</SP>, e<SP>2</SP>, f<SP>1</SP> and f<SP>2</SP>, may be different.

Thermionic amplifiers, detectors, and heterodyne receivers; undesired signals, eliminating.- The incoming signals are multiplied in frequency or are combined with currents of approximately multiple frequency, and the resulting oscillations are then re-combined with the incoming oscillations. As shown in Fig. 1, the incoming signals (for example, of frequency 100,000) are applied to the grid of a valve V<1> arranged to produce harmonics in its plate circuit B, which in the example shown is tuned to the frequency 300,000. The incoming signals are also amplified by a valve V<2>, giving a frequency 100.000 in the circuit C. The circuits B, C are coupled to similar circuits D, E arranged in series in the grid circuit of a valve V<3>, which produces currents of the difference frequency 200,000 in the circuits F, G. After heterodyning with a local source H of frequency 201,000, beats of frequency 1,000 are produced in the telephone. In a modification, the multiple frequency 300,000 is combined with a local frequency of 199,000 producing a frequency of 101,000 which is re-combined with the original signals to produce audible beats of frequency 1,000. In another modification, shown in Fig. 3, the incoming signals are amplified by the valve V<1> and are then combined in the valve V<2> with local currents of frequency 201,000, producing a difference frequency 101,000 in the circuits E, F. This is re-combined with the original signals in the valve V<4> and produces audible beats in the plate circuit of this valve.

Filed: 1956-02-21
Abstract: 810,662. Supplying fuel to burners. BRITISH THERMOSTAT CO. Ltd. Jan. 29, 1957 [Feb. 21, 1956], No. 5392/56. Class 75(1) [Also in Group XXVI] Fuel oil is alternately supplied to two areas of a burner through the operation of a pivoted deflector plate 11, Fig. 1, which is intermittently actuated by a heat operated motor comprising an air-tight assembly having chambers 1, 2, 3. The assembly is partially filled with water, &c. and is mounted on a pivot 4 so that the chambers may alternately contact a hot-plate 5 which heats and vaporizes the liquid within the chamber in contact at any given time. An ensuing see-saw motion is caused by the repeated vapour transfers and condensation. An adjustably secured weight 8 accelerates the assembly movement in both directions once dead centre has been passed. Each burner area has a fuel inlet pipe, either 16 or 17, and oil flowing into a chamber 10 is diverted to one or the other in dependence upon the position of the plate 11. The hot-plate may be heated by conduction or radiation from the burner. In another motor, the hot plate 18, Fig. 3,-alternately heats and expands metallic bellows 19, 20, carried by a pivoted member 23. An arm-andspring assembly 25, 28, 29, form a toggle mechanism which imparts a snap action to the movement of the member 23. By adjusting the mechanism, or varying the mass of the bellows, or changing the contact areas between the bellows and the hotplate the interval between each see-saw movement of the member 23 may be altered. In a further motor a member 34, Fig. 4, is axially reciprocable between hotplates 37, 38, by the expansion of metallic bellows 30, 31. The member 34 is carried by bearings 35, 36 and a toggle mechanism 39, 40 gives a snap action to the assembly's movement. Bellows 19, 20, 30, 31, may be replaced by bi-metallic elements.
