Abstract: 893,860. Rotary pumps. KILLEN, D., and BLACKWELL, J. B., [trading as VIKING ENGINEERING CO.]. June 23, 1960 [July 28, 1959], No. 25787/69. Class 110 (2). A metering unit comprises a plurality of annular cylinder pumps 11, 12, i.e. each pump comprising three or more pistons which move in one direction around the annulus of the cylinder, with adjacent pistons constrained to close up and separate to produce a series of compressions and expansions in the space between them, appropriate inlet and outlet parts connecting with the cylinder, connected to meters 41, 42 and driven by an electric, or air-powered, motor 38, through an overload clutch 36 and a constant mesh gear train 32, 33, 34, the pumps being driven respectively by the individual gears 32, 33, through couplings 30, 31, and the pump outputs being variable by manual operation of respective adjusting-levers 15. The components are mounted on platforms which are relatively secured by stays, as shown in Fig. 1, and the unit is enclosed by a sheet-metal casing 46.

Title: Improvements in or relating to well-flow control devices
IPC: E21B43/14
Filed: 1962-07-05
Abstract: 1,008,383. Wells. SUN OIL CO. July 5, 1962 [Oct. 4, 1961], No. 25859/62. Heading E1F. A flow control device comprises an outer housing 16 adapted to be retrievably locked at a predetermined position in a well tubing string 13, and an inner housing 31 adapted to be retrievably fastened in the housing 16. The string is contained in casing 10 perforated at 11, 12 to communicate with production zones A, B. A landing nipple 15 included in the string is perforated at 17 above lower packing 14 and below upper packing (not shown). The housing 16 is latched to the nipple by a wire line tool, and carries packing 21, 22 on either side of perforations 19. The latches are associated with keys adapted to engage and fit within a groove in the nipple, the arrangement being that the keys stop the housing 16 at the nipple so that the latches may be set. A pressure equalizing member 25 may be operated by jars when it is desired to remove the housing 16 from the string. The housing 31 is latched to the housing 16 by a wire line tool, and carries packing 33, 34 on either side of perforations 38. Fluid from zone A follows a path 30 to pass through a choke 39 into the string above the device, a non-return valve 23 within the housing 16 preventing fluid flowing back into the zone. Fluid from the zone B follows a path 26 to pass through a choke 37 into the string above the device to mix with the fluid from the zone A, a non return valve 24 being incorporated within the housing 16. The string is plastic coated, and an abrasion resistant ring 28 which is opposite the zone A forms the lower connection of the nipple. In a modification for producing from a single zone, the member 25 is dispensed with, the fluid from the zone passing axially upward through the housing and discharging through a choke into the string above the device.

Title: Improvements in or relating to filament supports for electric lamps or like devices
IPC: H01K1/18
Filed: 1933-09-20
Abstract: 425,694. Thermionic valves. ISMAY & SONS, Ltd., J., Roden Street Works, and ISMAY, J., 10, Warwick Gardens, both in Ilford, Essex. Sept. 20, 1933, No. 26024. [Class 39 (i)] [See also Group XI] The filaments of electric incandescent lamps and like devices, for example thermionic valves, are supported by metal wires or rods 5 which, at their ends, are formed into polygonal or multi-sided loops 6 having straight or curved sides to provide a substantially point contact with a filament 8 passing therethrough. Preferably the sides of the polygonal loops do not lie in the same plane, thereby enabling any part of the filament to be inserted into a loop without threading it therethrough. The extremity 7 of the wire 5 may be bent or offset to form a tail to facilitate the insertion of the filament within the loop. In the example a series of radial filament-supporting wires 11 are provided in addition to the wires 5 projecting radially from the button 4 on the stem 3, so that two independent filaments 8, 14 can be mounted within a lamp, or a single filament can be looped alternately between the two rows of supporting-wires.

Abstract: 473,382. Mirrors. HARVEY, W. Sept. 28, 1936, No. 26240. [Class 52 (iv)] [Also in Groups XVIII and XV] A flexible mirror, of sheet metal, silvered pliable transparency, &c., is periodically bent alternatively about axes at right-angles to one another to give a changing distorted image of the observer. The mirror 2 is mounted in a casing 1, and is held at its corners by universal pivots 3, 4, 5, 6 which also allow one end and one edge to move inwardly. The buckling of the mirror is effected by bifurcated lugs 9, 10, 11, 12 which are thrust and pulled in turn by rods 91, 101, 11<1>, and 121, the rods 91 and 11 being coupled together by a link 21 and bellcranks 20 and 20<1>, and the rods 10<1> and 12<1> by a link 14 and bell-cranks 13, 131. A motor 30 rotates a mutilated pinion 35 to engage in succession pinions 29 and 19, which respectively swing the cranks 20, 201 and 13, 13<1> to and fro, to bend the mirror 2 alternately in directions at right-angles to one another. In modifications, the flexing may be effected by Bowden wires, by blasts of air, or by magnetic means. The mirror may have a design on the back and be illuminated from the rear, and the device may be controlled by coin-release mechanism.

Abstract: 519,171. Vapour-pressure engines; elasticfluid turbines. DOCZEKAL, R. Sept. 13, 1938, No. 26663. [Classes 110 (iii) and 122 (iii)] In a vapour-pressure engine a mixture of vapours generated in a boiler K is utilised as the working fluid, the vapours being obtained from a mixture of two or more liquids (a) which are insoluble or only partially soluble one in the other, or (b) which show a maximum or minimum boiling point at one particular ratio of the components. Examples of (a) water and one or more hydro carbons such as benzole; (b) acetone and chloroform; water and formic acid; phenol and alcohol all show maximum boiling points at particular ratios; and minimum boiling points are shown by alcohol and water; alcohol and benzole, or acetone and methyl alcohol. The mixed vapours from a generator K may be led to a turbine, or as shown to the cylinder M', of a reciprocating engine via a valve 1 Fig. 2, or the vapours may pass through a superheating coil U Fig. 3. Starting with a mixture of water and benzole after the expansion of the mixture in the cylinder M<1> the exhaust is led to a separating tank B<1> which separates out the condensed water, and the mixed vapours pass on to a compressor M<2> which causes condensation of part of the benzole. This benzole is separated by a tank B<2> and the remaining mixed vapours are again submitted to the same cycle and after three or more cycles a new supply of mixed vapours is admitted from the generator, and the contents of the separators B<1>, B<2> may be returned to the generator by pumps P<1>, P<2> via valves 12, 15. The condensed vapours may accumulate and be drawn off as liquids through valves 11, 14. In the modification, Fig. 3, the compressor M<2> is connected direct to the generator via a non-return valve R, and a pump P' returns liquid to the generator from the separator B, which is fluid-cooled. In a further modification the compressed mixture from the cylinder M<1> is led back direct to the generator K via a non-return valve.
