Abstract: 1,243,484. Heating particles in suspension. SELAS CORP. OF AMERICA. 11 June, 1970 [19 June, 1969], No. 28411/70. Heading F4B. Clay particles to be expanded are fed as a sheet like stream from feed roller 7 down through chamber 2 of rectangular cross-section, to be collected at the chamber bottom either individually after chilling, or as shown on a sand or ground soap foam covered movable belt 9, thereby forming an insulating cellular ceramic slab. The fuel supply to each row of opposed horizontal rows of diffused non-turbulent flame burners 14 in the furnace side walls, is so controlled that the smaller lighter particles are deflected along paths 25 by the combustion gases to land on the belt 9 to the left of the larger particles. The smaller particles are thereby exposed to the expansion temperature of 1900 F. for a longer time than the larger particles and so may expand up to the same final size. Some combustion gases are withdrawn through ducts 17 to preheat the fuel supply to the burners, the remainder exiting via vent 5 or cooling section 12 of the furnace. In a modification (not shown) all four furnace walls are provided with burners.

Inventor: THOMAS ALBERT
IPC: G05D13/08
Filed: 1958-09-04
Abstract: 866,555. Jet propulsion plant. BRISTOL SIDDELEY ENGINES Ltd. Aug. 28, 1959 [Sept. 4, 1958], No. 28432/58. Class 110 (3). An exhaust cone for the jet pipe of a gas turbine engine, of the kind having radially outwardly directed hollow struts of appropriate aerofoil cross-section for slidably engaging radially inwardly directed pins fast with the jet pipe, has at least the radially outer portion of each strut formed as a casting which is relatively thick at its radially outer end and tapers, in the radially inward direction, to a thickness approximately equal to that of radially inward, sheet metal structure to which it is butt-welded. The jet pipe 10, Fig. 1, and exhaust cone 11 are formed of sheet metal. The exhaust cone is located in the jet pipe by hollow struts cast in one piece having relatively thick roofs 14 and side walls 15 of faired cross-section which diverge at their radially inner ends to form flares 16. The side walls taper in thickness from that of the roof to that of the sheet metal of which the main body of the exhaust cone is formed. A boss 18 integral with each strut receives a locating pin 19 attached to the jet pipe. The jet pipe is provided with an annulus 20 of thicker material to which are welded the flanges 23 of hollow pin holders 24. The underside of the head 26 of the pin 19 engages a flange 25 of the holder 24 and held thereon by two half-rings 27. In a modification, Fig. 4 (not shown), the major part of the side wall of each strut is formed of sheet metal and only the radially outer end is cast. In this case the pins 19 are held in position by cap nuts.

Abstract: 662,312. Powder metallurgy; extruding. DOW CHEMICAL CO. Nov. 7, 1949 [Nov. 12, 1948], No. 28508/49. Class 83 (iv). [Also in Group II] A method of making an extruded article of a magnesium-base alloy (see Group II) comprises atomizing the alloy into microinhomogeneous particles of from 0.001 to 0.02 inch in diameter, heating to a temperature within the range of plastic deformation of the alloy and applying pressure to compact and extrude the alloy, the reduction in cross-section being at least 80 per cent. Molten metal is atomized (see Group II), fed into a heated container 20 and extruded through a die 21 by a hydraulic plunger 25. Before extruding, the die opening 22 is temporarily plugged with a piece of magnesium alloy 29. The container and die are maintained at a temperature within the plastic deformation range of the alloy and preferably about 600‹ to 800‹ F. The charge should be compressed and extruded before its microinhomogeneous structure is adversely affected by the heating. Suitable ratio of extrusion are 2 to 20 feet per minute. The waste 31 left after extruding forms a temporary seal while the container is being re-charged.

Title: Improvements in follow-up mechanisms
IPC: G05D3/12
Filed: 1938-10-01
Abstract: 503,127. Electric control systems. ANSCHUTZ & CO., GES. Oct. 1, 1938, No. 28583. Convention date, Oct. 21, 1937. [Class 40 (i)] Hunting of a follow-up device is prevented by an eddy current brake associatcd with the motor of the device und operated, when the follow up device approaches the position determined by the control, by the anode current of a valve the grid voltage of which is dependent on the control voltage applied to the motor. The invention, as shown, is applied to the system described in Specification 230,111, [Class 40 (i)], comprising a transmitter 1 and receiver 2, voltages due to want of correspondence of which are amplified by valve 4 and fed to one phase 12 of the follow up motor 13. Part of the output of valve 4 is rectified and used to bias valve 9 the anode circuit of which includes the winding of an eddy current brake 11 mounted on the motor shaft. The arrangement is such that want of correspondence between receiver and transmitter causes valve 9 to be paralysed and the brake ineffective, but when the receiver approaches correspondence, flow of anode current energizes the braking winding and prevents hunting. Specification 252,060, [Class 38 (iii)], also is referred to.

Title: Improvements in and relating to the formation of flux layers on galvanizing baths
Filed: 1945-10-29
Abstract: A floating flux layer is formed on a galvanizing bath by injecting a flux-forming agent into the bath to a depth such that substantially all of the reagent reacts with the metal prior to its subsequent arrival at the atmosphere surface of the bath.  A flux of zinc ammonium chloride may be formed on a zinc bath by dropping or throwing briquettes of ammonium chloride through the surface of the zinc.  A saturated aqueous solution of ammonium chloride may be injected below the surface by a pipe or through the surface by a jet from a nozzle.

Title: Improvements in or relating to absorption refrigerating machines
IPC: F25B15/10
Filed: 1927-10-29
Abstract: 279,898. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Oct. 30, 1926, [Convention date]. Refrigerating, absorption machines and systems for.-In continuous-cycle systems of the kind described in Specifications 251,251 and 259,985, wherein the refrigerant is evolved from low temperature solution in a vessel 1, Fig. 1, to produce cold, mixes with an inert gas and passes to an absorber 12, while the gas evolved in the heated generator 15 is passed to a re-absorber 7 to provide a rich solution for the low-temperature generation, the injector nozzle 10 for increasing the gas circulation is supplied with inducing-gas from a source 20 separate from the main generator. This source may be at a higher pressure than the main generator, due to its location below liquid columns, and may receive separate heat from outside or be heated by the weak liquor or expelled gas flowing from the main generator. Gas evolved in the generator 15 raises the liquor with it to a separator 18, whence the weak liquor flows to the vessel 20 and the gas passes through a pipe 6 and serves to lift the liquor flowing through pipe 3 from the vessel 1 into the re-absorber. The enriched liquor flows from the reabsorber through pipe 2 to the vessel 1. The vessel 20 is heated by an electric element 22, and the gas evolved passes to the nozzle 10 to induce circulation of gas mixture in the direction shown by the arrows, while the liquor rises through pipe 13 to the top of the absorber. Since the liquid column in pipe 13 is higher than that in the return pipe 14 from the absorber to the generator, the pressure in vessel 20 and of the gas passing to the nozzle is greater than that in the generator 15. The quantity of gas evolved in vessel 20 is regulated automatically, since when little liquor is present the heatirg element is partly uncovered and less effective. In a modification, the vessel for generating the gas for the nozzle is supplied with liquor from the pipe conveying liquor to the re-absorber, and is heated by a pipe conveying warm weak liquor from the generator to the absorber. In the arrangement shown in Fig. 3, gas from the seperator 79 above the generator 77 is passed through a coil 81 and serves to heat liquor in a vessel 65 for generating the gas supply for the nozzle 55. After passing through the coil 81 the gas enters a rectifier 74, supplied with strong liquor from the absorber 53, and then flows through a pipe 83 to a collecting vessel 59 and to the pipe 57, returning liquor from the cold generator 50 to the re-absorber 62. The pipe 57 leads to a collector 60 which supplies liquor to the re-absorber through a pipe 61 and to the vessel 65 through a pipe 64. A liquid trap 70, 67 prevents flow of gas from the vessel 65 direct to the collector 59. The various liquor pipes may be arranged as heat interchangers.
