Title: Method of and apparatus for deriving hydrogen from dissociated liquid ammonia
IPC: C01B3/04
Filed: 1964-06-22
Abstract: <PICT:1022521/C1/1> In the preparation of hydrogen by the catalytic cracking of ammonia followed by separation of hydrogen by selective diffusion, the temperature and pressure during cracking are such that the product gas mixture may be passed directly to the diffusion apparatus, the pressure therein being governed by the pressure at which liquid ammonia is supplied to an evaporator and the rate at which hydrogen-depleted gas leaves the diffusion apparatus.  Suitable cracking conditions are 1100-1500 DEG  F. and 50 to 1000 p.s.i.g.  In the drawing, pump 13 pumps liquid ammonia from reservoir 10 via lines 12 and 14 to evaporator 20, relief valve 15 maintaining the pressure in the feed line 14 at, e.g., 200 p.s.i.g. Ammonia vapour passes via line 21 to cracker 23 containing catalyst 25, which may be 0.5% rhodium on alumina, iron oxide, potassium oxide activated iron or nickel.  Pressure within the cracker is maintained by valve 28a.  The cracked gas mixture passes to diffusion unit 30, having diffusion element 34 formed of, e.g. a palladium silver alloy, and closed at end 34a. Hydrogen is withdrawn through line 35 by pump 36, while the hydrogen-depleted mixture leaves chamber 31 via outlet 32, variable restriction 33, in co-operation with valves 28a and 15 mani-taining the pressure within the diffusion chamber.

Title: Improvements in or relating to a method and apparatus for the manufacture of finned tubing
Inventor: MADDOCKS JOHN LEONARD
IPC: B21C37/22
Filed: 1963-06-28
Abstract: 1,080,874. Making finned tubes; welding by pressure. INTERNATIONAL COMBUSTION (HOLDINGS) Ltd., and PHOENIX STEEL TUBE CO. Ltd. June 22, 1964 [June 28, 1963; July 31, 1963], Nos. 25883/63 and 30452/63. Headings B3A and B3R. A method for the formation of externally finned metal tubing comprises feeding strip 1 into a tube forming machine 3 cutting the tube into desired lengths and at an intermediate stage thereto, securing fin stock in position on the tube. The formed tube 4 passes through a cooling device 5 and a sizing device 6 after being formed and its abutting edges welded by electrodes in the machine 3 and may be fed to a machine 7 to he rolled to an oval cross-section. Wire for the fins is supplied from reels 8 and is welded to the tube by electrodes located slighty in advance of pressure rolls 10. The welds are scarfed by tools (not shown) which are mounted such that they can be withdrawn quickly by means of a mechanism interlocked with a weld power control. Tube movement is maintained by pull-out rolls 12, the tube passing through a cooling device 13, a fin trimming device 14, forming rolls 15 to restore it to a round crosssection, if required, and flying cut-off machinery 16. Welding current of 400-450 kc/s. per second flows from one electrode to the other via the surface of the tube. The area of contact between fin and tube at the rolls 10 and the fin wire to the other electrode raises the temperature sufficiently to enable the rolls 10 to forge the fin wires to the tube.

Title: Improvements in or relating to braking systems for aircraft
IPC: B64C25/48
Filed: 1932-09-17
Abstract: 407,392. Aircraft wheel-braking systems. VICKERS (AVIATION), Ltd., PIERSON, R. K., and DUNCAN, T. S., Byfleet Road, Weybridge, Surrey. Sept. 17, 1932, Nos. 25919/32 and 6357/33. [Class 4.] A fluid-pressure braking system for aircraft, capable of differential operation, includes a parking control which is arranged to override the normal functioning of pressure-reducing governor-valves and, when operated, to apply to the brakes the full pressure available from the source. As shown, a compressed-air cylinder 10 is connected by a conduit 11 with inlet ports 12 of the governor valves 13, the outlets 114 of which are connected bv conduits 14 with inlet ports 15 of two, one for each wheel, parking valves 16 connected by conduits 17 with the brake cylinders 18 which control the brakes. Conduits 21 connect the valves 16 through valves 125 to the cylinder 10 so that, on throwing the lever 116 over into the position shown in dotted lines, cam means at its pivot causes the member 128 to descend to close inlet valves 115 and open the valves 125 to the full pressure obtaining in the cylinder 10. Each governor valve is provided with an inlet valve 112 and an exhaust valve 122, the stems of which are connected to a rack-plate 24 articulated on a diaphragm 28. Actuation by the pilot of a control 30 against the action of a spring 35 depresses through Bowden-wire mechanism and a lever 33 a slide 40 carrying a rocking- lever 37, which in turn, through springs 29, depresses the diaphragms 28 to close the exhaust valves 122 and open the inlet valves 112. In order to obtain differential application of the brakes, movement of the rudder bar 26, after the control 30 has been actuated, turns the rocking-lever 37 thus causing unequal pressure on the two diaphragms and in consequence unequal opening of the valves 112. In a modification the governor and parking valves shown diagrammatically in Fig. 1 are combined in a single unit ; in this case, a control 61, Fig. 5, actuates a pair of levers 60, each of which forces a rod 63 into contact with a member 44 engaging a spindle 45 on the diaphragm 28 thereby maintaining the exhaust valve 122 closed and the supply valve 12 open. The movement of the rudder bar is communicated to the rocking-lever 37 through an Oldham's coupling 55 .. 58. The connection from the rudder bar includes a lost-motion device so that no turning movement is imparted to the rocking-lever 37 during about the middle third of the rudder movement and lost motion is provided between the rocking-lever 37 and the springs 29 to prevent application of the brakes until the control 30 has been actuated. Specification 398,892 is referred to in the first Provisional Specification.

Title: Improvements in or relating to the colouration of textile materials
IPC: D06P1/32
Filed: 1936-09-25
Abstract: Aniline-black dyeing; cellulose esters or ethers, dyeing; regenerated celluloses, dyeing.-Colourations of the aniline black type are produced upon textile materials, e.g. regenerated cellulose, cellulose esters or ethers or cotton, in wound package form, by impregnating with a liquor, of which at least 60 per cent is a volatile organic liquid, containing a suitable aromatic amine and subsequently oxidizing the amine upon the material.  The organic liquid, which should have a boiling point approximately equal to or less than that of water, may be, for example, acetone, lower boiling alcohols and ethers, dioxane or methylene ethylene ether or a mixture of two or more of such liquids may be used. Some water may be included to aid in the solution of the ingredients.  The oxidizing-agents may be chlorates and as catalysts copper sulphate, cupric chloride, potassium ferrocyanide and ammonium vanadate are specified.  When cellulose acetate or other cellulose derivatives are being dyed the processes described in Specifications 332,624, [Class 15 (ii)], and 390,819 may be applied.  In an example regenerated cellulose yarn wound on a bobbin with a perforated barrel is impregnated with a liquor containing acetone (69 per cent), water, aniline hydrochloride, sodium chlorate and cupric chloride by circulating it through the windings on the bobbin; excess liquor is removed by centrifuging, the bobbin dried and oxidation effected by drawing damp air through it at 40 DEG  C., it is then subjected to the usual afterchroming and washing.  Other specified amines are p-phenylene-diamine, p-amino-diphenylamine and p-amino-phenol. According to the Provisional Specification petroleum or aromatic hydrocarbons may be used in admixture with the organic liquid.

Title: Method of making pellets coated with a finely divided material
IPC: B01F33/40
Filed: 1956-08-28
Abstract: 813,552. Making coated pellets. G. & A. LABORATORIES Inc. Aug. 28, 1956 [Sept. 21, 1955], No. 26319/56. Class 87(2). A method of making coated pellets comprises rotating a mass of finely divided coating material, e.g. clay particles, by means of blades attached to a horizontal shaft, adjusting the speed of rotation of the shaft so that the top surface of the mass is above the axis of rotation but below the top arc of travel of the blades, distributing liquid droplets, of molten material e.g. rosin, over the mass and maintaining the temperature of the mass below the solidification point of the droplets to form coated pellets. The liquid droplets and the coating may be of the same material. Rosin, clay, thermoplastic resins, asphalts, waxes and ammonium nitrate are mentioned. The method may be performed in an open topped container 10 having a rotating shaft 11 with spiral blades 12, an outlet 15 with a valve 16 leading to a further container 22, and a liquid supply pipe 17 with nozzles 18. The container 22 has an inclined screen 19 leading to a receptacle 24 and an outlet 25 leading to two screw conveyers 26, 28 arranged to discharge into a funnel 29 on the first container 10. In operation, the container 10 is loaded with a mass of particles 30 and the shaft 12 rotated, thus resulting in a "beating" of the mass 30 by the blades 12 and causing air to be trapped in the mass and the mass to expand so that its top level is between the axis of the shaft 11 and the top arc of rotation of the outer edges of the blades 12. Liquid droplets emitted from the nozzles 18 fall onto the agitated mass, rotate with it and become coated with a film of the particles. Opening of the valve 16 causes the pellets to fall onto the screen 19 from whence they are removed to the receptacle 24, excess particles passing through the screen and being returned to the container 10 by the screw conveyers 26, 28. Specification 812,166 [Group III] is referred to.

Abstract: 895,264. Thermal switches; cam-operated switches. PROCTOR - SILEX CORPORATION. July 29, 1960 [July 31, 1959]. No. 26427/60. Class 38 (5). [Also in Group XXXV] The co-operating contacts 37, 38 of a switch are carried on bimetal strips 39, 47, respectively, the former being the main strip and being heated by a winding 40 controlled by a sensor element responsive to the temperature of a surface heating unit being controlled. In order to speed up the opening of the contacts to reduce arcing, the bimetal 47 is of low thermal mass and is heated partly by conduction through the contacts and partly by the current through the contacts. Thus when the contacts separate a fraction, heating of the strip 47 ceases and it moves rapidly to the right, Fig. 3, thereby increasing the contact gap. The cooling of strip 47 is speeded by heat flow into a supporting member 50 and an ambient temperature compensating bimetal 49. The operating temperature is set by a cam track 54 on a cam 53 which forces contact 38 to the left (Fig. 3); contact 37 is adjustable to a small extent by a screw 45 acting on a member 44 connected to bimetal 39 at 42. The cam 53 has a further track 53a acting on a forked spring arm 26, one fork 25 having an on-off contact 22 co-operating with a fixed contact 21, and the other fork 31 having a contact 31a co-operating with a contact 32 in an indicator circuit.
