Title: Improvements in or relating to vapour generating and superheating units
IPC: F22B29/08
Filed: 1947-06-13
Abstract: 633,381. Forced flow steam boilers; superheating. BAILEY METERS & CONTROLS, Ltd. June 13, 1947, No. 15614. Convention date, June 14, 1946. [Classes 123(ii) and 123(iii)] In a forced-flow steam boiler 1 comprising serially-connected steam generating and superheating sections 13, 14 in the form of parallel helically-wound tubes lining a combustion chamber above a furnace 2, an economizer 10 constituted by one or more parallel conduits, and a steam separator 37, the separator is adapted to be connected to one of a number of pre-selected locations along the sections 13, 14 so as to enable the ratio of steam generating surface to superheating surface and, hence, the final superheat temperature, to be varied. The invention is shown applied to an installation including ahead and astern turbines 42, 43 utilizing steam at 900‹F. and 750‹F. respectively from the outlet 16 of the boiler through throttle mechanism 44, in which case the sections 13, 14 are provided at two locations with outlet and return conduits 48, 49 and 50, 51 which have interposed valves Q, S respectively and are connected to the separator 'by conduits 52, 54, 53, 55 with valves P, T, R, U. With the valves P, T, S, open and the valves Q, R, U closed, wet steam will flow through the conduits 48, 52 to the separator and dry steam return through the conduit 54, 49 to be superheated to the higher temperature, but with the valves Q, R, U open and the valve P, T, S closed, the conduits 50, 51 will be in communication with the separator and the steam from the latter will be superheated to the lower temperature. The several valves may be actuated automatically by a switch 45 connected to the throttle mechanism 44 in such a manner that, with the throttle admitting steam to the ahead turbine 42, the switch 45 is in the position shown, closing circuit with a contact 900 to energize a relay 46; the latter closes a contact 56, and solenoids associated with the valves P, T, S will be energized to open these valves. When the throttle is actuated to direct steam to the astern turbine 43 the switch 45 moves to the dotted line position-750, whereupon the relay 46 is de-energized and contact 56 opened, the valves P, T, S are closed and the valves Q, R, U opened. A normally-closed hand switch 47 may be provided for cutting out the automaticcontrol, both turbines then operating at the lower temperature. Specifications 410,091, 410,102, 481,921, and 482,611, [both in Group XXIX], are referred to.

Title: Improvements relating to metallic alloys, and the processes for their production
IPC: C22B9/00
Filed: 1930-05-21
Abstract: In the production of homogeneous alloys the melting pot in which the fusion takes place is positioned in an electrostatic non-oscillating field between two insulated metallic electrodes which are connected to a source of high tension electricity.  For example 90 per cent of commercial iron and 10 per cent of electrolytic copper are introduced into a melting pot arranged in such a field in a furnace, and the mixture is stirred with a refractory stick.  Fusion is prolonged for 5-10 minutes and the alloy is cast in a mould preferably arranged in the electric field.  A third metal, for example tin, may be added to the alloy.

Abstract: 1,025,384. Seals. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 4, 1963 [April 25, 1962], No. 15700/62. Heading F2B. A sealing device for controlling leakage of fluid between a casing and a rotatable shaft or collar secured to the shaft comprises a soft packing ring held by means of a jacket or an open-cage-like member, a sealing member between the casing and the jacket or cagelike member, and a connection for applying pressure medium to the packing ring to vary its sealing contact with the shaft or collar. In Fig. 1, the packing ring 1 is held in a non-rotatable jacket 3 of plastic material contained in a recess 4 in a stationary casing 5 and floatingly supported by a spring 6. The fluid being sealed enters the chamber 4 and acts on to the jacket to press the packing ring 1 against a shaft 2. In a modification, Fig. 2 (not shown), the spring is dispensed with and the jacket 3 is sealed on both sides to the casing, pressure medium, which may be the fluid being sealed or fluid under manual control, being supplied to the recess in the casing. In a further modification, Fig. 3 (not shown), the packing ring 1 is normally loose on the shaft 2 and is forced thereon, when required, by supplying fluid to the recess 4 by means of a pump 7, the pressure being controlled by a relief valve 8. In another embodiment, Fig. 4 (not shown), two spring-loaded packing rings 1 are held by an open-cage-like member 9 to which grease is supplied from an hydraulic intensifier 10. In a modification, Fig. 5 (not shown), the spring 6 is dispensed with and a cage-like member 9 is provided for each packing ring, a part of each member 9 forming a bearing surface against the shaft 1. In a further modification, Fig. 6 (not shown), the middle spring loading the rings is also dispensed with and the two cages are joined by a waist which forms a bearing against the shaft. In a further embodiment, Fig. 7 (not shown), a mechanical sealing arrangement is formed by two soft packing rings 1 loaded against a collar 11 on the shaft by grease supplied to a recess 4 in an axially floating member 13 which is movable against a spring 6 so as to act on the packing rings 1 via the cagelike member 9. A plastic pad 12 is carried by the member 13 to engage with the collar 11 when the packing rings 1 are worn. In a modification, Fig. 8 (not shown), only one packing ring 1 is provided and the cage-like member is an integral part of the member 13. In a further modification, Fig. 9 (not shown), the mechanical sealing arrangement is normally effective but in the event of its failure or replacement, a jacket-type sealing device 1, 3 comes into operation.

IPC: H01J25/12
Filed: 1964-04-17
Abstract: 1,038,258. Transit-time tubes; electron multiplier tubes; cathode-ray tubes. STANDARD TELEPHONES & CABLES Ltd. April 17, 1964 [April 19, 1963], No. 15987/64. Heading H1D. An electron discharge device has bunches of electrons which form a beam generated by multipacting between secondary electron emissive surfaces forming part of a cavity resonator, electromagnetic energy being imparted to an electromagnetic field in a further cavity resonator. In one form, Fig. 2, the bunches are formed by multipacting between two curved secondary electron emissive surfaces 23, 24 which forms the end faces of a re-entrant resonator 4, Fig. 1 (not shown), a central aperture in one surface allowing annular bunches of electrons to be accelerated through a hollow cylinder 26, Fig. 1 (not shown), acting as an anode towards a further resonator. In another form, Fig. 7, the electron emissive surfaces 39, 43 are coaxially disposed around the tube axis, one, 39, being formed on the re-entrant portion of the resonator which extends through an aperture in the opposite end face, the relatively large diameter electron rings formed being electrostatically focused to a smaller diameter before they are incident upon a gap in a second resonator. Both cavities may be tuned by a differential screw and flexible bellows arrangement. Multipacting between the emissive surfaces is obtained by making the transit time between the surfaces equal to an odd number of half the period of the R.F. field applied to the cavity; this produces phase-focusing in which the time of arrival of electrons at the surfaces becomes closely synchronized after several transists. The annular bunches of electrons are emitted from the gap by a combination of space charge forces, applied anode field penetrating the gap, and the geometrical shape of the surfaces.
