Title: Improvements in or relating to heat exchangers
IPC: F28D19/04
Filed: 1946-06-17
Abstract: 613,283. Heat-exchangers. RICARDO, H. R. and GRAHAM, I. E. June 17, 1946, Nos. 18141/46 and 4852/47 [Class 64(i)] Relates to heat-exchangers of the regenerative type in which a rotatable member having a matrix of heat-conductive material is traversed alternatively by two fluid streams. According to the invention, a heat-exchanger is provided with a spherical or near-spherical rotor rotatably mounted in a casing having an internal shape conforming to that of the rotor, passage ways leading through the walls of the casing parallel to the rotor shaft so that gases can flow in opposite directions through the matrix carried by the rotor. In addition, radial partitions in the rotor are equally spaced circumferentially and heat-absorbing material is placed between the partitions. Into grooves along the shaft A are inserted the straight edges of approximately semicircular discs forming radial partitions B. Curved plates C are placed between the partitions B to form an annulus surrounding the central portion of the axial length of the rotor. Radial pins D between the plates C and rotor shaft hold in place heatabsorbing elements E. The edge of each partition B is grooved to accommodate a sealing strip which itself has a groove and spaced pockets filled with a graphite composition or other anti-friction substance. The matrix elements E may comprise corrugated plates alternating with plain plates or ceramic material. The casing is made in two parts G, H bolted together, each halfcasing having two passage-ways G<2>, G<3>, H<2>, H' projecting on opposite sides of the shaft A, each passageway having a flange for the attachment of piping. The passage-ways of the two halfcasings are aligned to provide two passages through the heatexchanger, hot gas passing through one passage G<2> H<2>, and cold air through the other H<3> G<3>, the hot gas giving up heat to the matrix elements and the cold air being heated by the matrix element as they sucessively pass through the two media. The shaft A is mounted in a free bearing J at one end to allow for expansion and at the other end is a locating bearing K this end being connected through reduction gearing to the drive. Spaces J<1>, K' are provided around each bearing for circulation of a coolant. The sealing strips effect sealing in two sealing zones G<x> formed by the casing. These zones limit the cross-sectional area of the passage-ways and are of such a width that at least one sealing strip is always passing across each zone. A modified form of rotor is described in which the matrix elements are built up into an oblate spheroidal shape. In this form a bi-metallic strip may be placed behind each sealing strip to maintain sealing pressure under operating temperatures. A modified casing is also described.

Abstract: 1,129,753. Producing circular polarization. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 31 March, 1967 [26 April, 1966], No. 18294/66. Heading H1W. A circularly-polarized wave is produced by feeding two waves in time and space quadrature and of equal amplitude to a cruciform waveguide E which is coupled by a transition section (not shown) to an output waveguide of circular section. The two waves are fed respectively through rectangular waveguides A, B whose corresponding axes lie in orthogonal planes. The necessary 90-degree phase difference between the waves may be ensured by deriving them from the output ports of a directional coupler, e.g. a multihole broadwall coupler, fed from a common source. The bandwidth of the circuit is determined by the bandwidth of the coupler.

Title: Improvements in or relating to Relay Motors.
IPC: G05D13/00
Filed: 1917-12-13
Abstract: 119,951. Marks, E. C. R., (Lang, L. A., Lang, W. G., and Roberts Bros.). Dec. 13, 1917. Starting-engines.-In relay-motors with followup mechanism such as used in reversing the valvegears of locomotives &c., poppet exhaust valves 21, 22 are arranged in a housing 18 on the piston 14 and are actuated by a control-rod 10 which operates a rook-lever 33 pivoted on a shaft 34 and which has arms 38, 39 with tappets 40, 41. Lugs are provided to prevent excessive movement. The valve pockets 25, 26 communicate with opposite ends of the cylinders through the hollow piston 14. Fluid is supplied to the cylinder-ends through a passage 53 and lift valves 50, 51 which are controlled by differential pistons 54, 55 the upper ends of which move in equalizing-chambers 57, 58 communicating with opposite ends of the cylinders. Operation of one or other of the valves 21, 22 by the rod 10 or the movement of the piston causes a reduction of pressure in the corresponding end of the cylinder, and thereby a supply of fluid to the oposite side of the piston through one of the valves 50, 51. Any movement of the piston in either direction due to external forces will cause a building up of the pressure on one side to oppose such movement. A permanent unbalanced load on the piston can be allowed for by having different sized pistons, or, if springs are mounted above the pistons, springs of different strengths.
