Abstract: 664,098. Heating air. FOSTER WHEELER, Ltd. May 27, 1949 [June 9, 1948], No. 14239/49. Class 64(iii) In a vapour generator, heat is extracted from the hot gases and is transferred to a fluid (e.g. combustion air), by a liquid circulated through two heat exchangers, one located in the hot gas stream and the other in the stream of fluid to be heated, means being provided to prevent boiling of the circulating liquid and the rate of circulation of the liquid being controlled in response to the flow of the vapour in the vapour outlet of the vapour generator. In the form shown the circulating liquid, e.g. water, diphenyl or diphenyl oxide is circulated by a pump 50 and passes from a reservoir 29 to a heat exchanger 25 located in the fiue 23 of a steam generator which includes steam and water drums 11, 14, a bank of steam generating tubes 13 and a superheater 15. From the heat exchanger 25 the liquid is circulated through a second heat exchanger 45 located in the air duct leading to the burners 12 and thence through the pump 50 and conduit 52 back to the reservoir 29. To maintain the pressure in the circulating system above the vapour generating point a relatively small quantity of the circulating fluid above a baffle 29<SP>1</SP> in the reservoir is heated by a steam coil 34 provided with a control valve 71. The flow of circulating fluid through the system is controlled in accordance with the amount of steam passing through the outlet conduit 18 of the superheater, by means of a pressure responsive device 55 which, through a rheostat 61, regulates the amount of circulating fluid by varying the speed of the pump 50. In a modification, Fig. 4 (not shown), the baffle 29<SP>1</SP> is omitted, the return conduit 52 communicates directly with the outlet 27 from the reservoir and liquid returning to the reservoir is mixed with the outflowing liquid to avoid substantial mixing at the liquid level in the reservoir.

Title: Improvements in and relating to gyro-verticals and to erecting means therefor
IPC: G01C19/44
Filed: 1944-07-31
Abstract: 601,447. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. July 31, 1944, No. 14590. Convention date, July 31, 1943. [Class 97 (iii)] In a gyro vertical in which electromagnetic erecting torques are provided by a pendulous universally mounted magnet acting on a conductor mounted on the rotor case and spinning about a normally vertical axis, the conductor is so shaped that the amount of magnetic flux passing through the conductor diminishes as the angular displacement between the conductor and magnet increases and the magnitude of the erecting torques is thereby kept substantially constant. The invention may be applied to a gyro vertical of the type described in Specification 591,400. As shown, in Fig. 3, the rotor casing 27 pivots about a transverse axis in a U-shaped gimbal ring 28, having an elongated trunnion pivoting about a fore and aft axis at the rear of the instrument. An electromagnet 33 normally coaxial with the rotor spin axis is carried by a pendulous bail 35 pivoting about a transverse axis 56 in a second U-shaped gimbal ring 34 which in turn is pivoted coaxially with the gimbal 28. The electromagnet 33 co-operates with a copper or aluminium conductor 36, which is fixed on and spins with the rotor axle. As shown in Fig. 3, the conductor is of conical shape with a cylindrical boss at the apex. To disable the torque existing means when the supporting aircraft is diving, a projection 55, Fig. 6, on the bail 35 is adapted to engage a spring arm 53 on the gimbal 34 and open a switch 49 in the circuit of the electromagnet 33. Alternatively, a shield fixed to the underside of the gimbal 34 near its pivotal support is adapted to be interposed between the magnet and conductor when the aircraft dives. The movement of the pendulous magnet 33 is limited about the transverse axis by the engagement of an arm 60, 61, on the bail 35 with spring stops 58, 59, on the gimbal 34 and about the fore and aft axis by the engagement of a rubber or felt bumper 62<1> on an arm 62 fixed to the trunnion of the gimbal 34 with a pair of stops 64 fixed to the outer casing 20. A pair of pivoted dash-pots 66 damp the oscillations of the gimbal 34 about the fore and aft axis. Fig. 9 shows a modification in which a conductor 36 in the form of a cap of a sphere is provided with perforations 73 increasing in size with distance from the spin axis so as to decrease the flow of eddy currents in proportion to the angular displacement between the magnet and conductor. Fig. 10 shows a further modification in which the thickness of the cap decreases with distance from the spin axis.

Abstract: 861,714. Photographic cameras. PAILLARD S.A. April 30, 1959 [June 4, 1958], No. 14732/59. Class 98(1) A camera having a device for the securing of a detachable release cable, comprises a seating adapted to receive the end of said cable and a release pusher located in said seating characterised in that the said pusher is shaped so that its front end closes the opening of the said seating against the entry of foreign bodies, and the release mechanism has an idle stroke permitting of the mounting of the cable after the pusher has been pushed axially against the action of yielding means which maintain it in an advanced position in the absence of the cable. As shown, the release pusher 7 has a cylindrical end portion 2 adapted to close the opening of seating 1, and is urged into its forward position by the action of spring 10 on pivotable lever 8. On attachment of a cable release in seating 1, the pusher is displaced inwardly and lever 8 is rotated an amount corresponding to the idle stroke e. When the cable release is depressed, the pusher is displaced further, and lever 8 is pivoted against a spring urged locking member 12, the resultant movement of which actuates release of the shutter driving mechanism. In an alternative embodiment (Figs. 7 and 8), the seating is drilled in the normal release knob of the shutter, and the slide pusher actuates the same release lever as this knob. In modifications, the screw-thread connection between the seating and cable may be replaced for example by a bayonet joint.

Abstract: 514,858. Extracting zinc, lead, and cadmium. AMERICAN ZINC, LEAD & SMELTING CO. May 17, 1938, Nos. 14734 and 14735. Convention dates, June 1, 1937, and June 28, 1937. Drawings to Specification. [Class 82 (i)] [Also in Group III] Lead and cadmium are recovered from the sinter fumes of calcined zinc concentrates by precipitating the fumes, oxidizing them, and treating with sulphuric acid, whereupon the lead sulphate is separated by filtration, and the filtrate is then treated with zinc dust to precipitate the cadmium. When the raw concentrates are calcined the fumes, rich in lead and cadmium, are electrically precipitated and mixed in desired proportions with the solid calcine and with fuel. The mixture is sintered yielding a solid product which is then reduced to zinc, and fumes which are electrically precipitated. This precipitate is roasted at 200-450‹C. and treated with sulphuric acid. The roasting may be omitted if an ixodizing agent such as sodium chlorate is added to the acid. The precipitated lead sulphate is filtered off, and the filtrate is treated with zinc dust and sulphuric acid. The precipitated cadmium sponge is filtered off and the remaining zinc chloride liquor is used to moisten the mixture fed to the sintering machine. The cadmium sponge is dried, mixed with lime and fuel and distilled.

Filed: 1945-06-12
Abstract: 593,119. Electromagnetic relays. AUTOMATIC ELECTRIC LABORATORIES, Inc. June 12, 1945, No. 14818. Convention date, June 12, 1944. [Class 38(v)] A relay of the slowrelease type, and with a release time which does not vary with reasonable variation in voltage or contact spring pressure, has a copper sleeve surrounding the core 12 and of such dimensions that if the relay were energized by a voltage of one third the normal operating voltage the current flowing in the copper sleeve immediately after the breaking of the relay winding circuit would be sufficient to saturate the magnetic circuit. The time of release may be varied by rotating a selflocking nut 47 which determines the position of an armature stop spring 29 having a rounded end portion 43 adapted to be engaged by the right hand end of an extension arm 17 of the armature 15. The air gap between armature and core when armature is in the attracted position is thus varied. The extension arm 17 also engages a stud 41 on a contact spring 27 moving two contacts on this into engagement with contacts on a forked contact spring 26. The spring 27 thus serves to bias the armature away from the core and when the relay is de-energized the arm 17 engages a projection on the heel piece 14 which is out of line with the stud 41 so that the armature is subjected to a twisting movement which takes up any play between the armature pivot pin 20 and its bearing surfaces of which the surface 19 is constituted by the bottom plate of the contact spring pile up.
