Abstract: 356,454. Electrolytic transmission of substances through glass. VEREINIGTE GLœHLAMPEN UND ELECTRICITATS AKT.-GES., Ujpest, near Budapest. Aug. 27, 1930, No. 25568. Convention date, Aug. 28, 1929. [Class 41.] In the oxidation of cathodes of vacuum or gas - discharge tubes, photo-electric cells, &c., wherein oxygen is introduced into the discharge tube or into a glass vessel connected therewith by heating the glass wall to render it con. ductive and passing an electrolytic current therethrough, a gas filling in the tube is ionized so that the electrolytic current may flow between internal and external electrodes. The gas filling may be ionized by the electrolytic current, or by a continuous or alternating-current discharge between internal electrodes, or by means of external annular electrodes connected to a high-frequency supply, or by placing the tube in an electromagnetic high-frequency field. A photo-electric cell 1, as shown in the Figure, is partially immersed in a bath of fused sodium nitrate and an electrolytic current is passed from a battery 7 through the bath 10 and the glass wall to a ring-shaped electrode 3. A temporary gas filling is used for vacuum tubes.

Abstract: 684,959. Elastic fluid turbines. SOC. RATEAU, and ANXIONNAZ, R. Oct. 5, 1949 [Oct. 6, 1948], No. 25624/49. Class 110(iii) Relates to a power plant including a gas turbine power set having an air compressor C and a gas turbine and a steam turbine power set having a steam producer Ch provided with a . furnace and a steam turbine TvAV wherein each set is adapted to provide useful power. According to this invention such a plant comprises valve controlled pipe means for supplying compressed air to the gas turbine and the furnace in inverse ratio and pipe means for feeding the gas turbine with combustion gases from the furnace. The compressor is driven by gas turbines TgHP, TgBP arranged in series, the exhaust gases from which heat the compressed air in a heater R and an economizer E for the feed water. The steam and gas turbine sets drive a shaft A<SP>1</SP> through gearing E<SP>1</SP> which is driven in reverse through stages TvAR of the steam turbine in which case the gas turbine TgBP is disconnected at A and by-passed by a valve O. In a modification the gas turbines drive the gearing E<SP>1</SP> through an electric transmission comprising a generator and a motor whereby the shaft A<SP>1</SP> may be reversed and the valve O and clutch A dispensed with. The gas turbines may then constitute a single unit. In a further modification, the high-pressure turbine and the compressor normally rotate in the opposite direction to that of the low-pressure gas turbine which is driven at no load by opening the valve O and coupling it to the high-pressure gas turbine. The high-pressure gas turbine, or an independent intermediatepressure gas turbine, drives an electric generator and a feed pump for the steam producer.

Title: Boiler for the recovery of the heat of a fluid under pressure
IPC: F22B1/18
Filed: 1961-07-14
Abstract: 909,557. Water-tube steam boilers; superheaters. BABCOCK & WILCOX Ltd. July 14, 1961 [July 16, 1960], No. 25686/61. Classes 123 (2) and 123 (3). A tubulous boiler in which the heating fluid e.g. the coolant gas from a nuclear reactor, is under pressure comprises a pressure vessel through which the fluid passes and has a lower part enclosing an economiser and steamgenerating tube bank, an intermediate steam and water separating drum, part of the wall of which forms part of the wall of the pressure vessel, and an upper part enclosing a steam superheating tube bank, the connections to the drum from the tube banks being enclosed within the vessel. Fig. 1A shows the upper part 4 of a cylindrical pressure vessel together with a spherical steam and water drum 6 and Fig. 1B the lower part 7 of the vessel. Water enters the boiler by a pipe 17 and rises through a helicoidal economiser tube bank 23 into a bulbous chamber 27 in which it mixes with water returned from the steam and water separating drum 6. The mixed water enters a helicoidal steam generating tube bank 35 through risers 32 and headers 33 and 34, the emergent steam and water passing through headers 41 and 42 and riser pipes 43 into an outer annular compartment 44 of the steam and water drum 6. The mixture of steam and water passes into a number of centrifugal separators 46 the water being discharged into the lower part of the drum 6 and returning via pipes 74 and downcomer pipe 37 to the mixing chamber 27. The steam passes through primary driers 47, secondary driers 52 and enters a helicoidal superheating tube bank 50 through riser pipes 53 and headers 54 and 55. Superheated steam leaves the boiler by pipes 61 at its upper end. The heating gases enter the pressure vessel at this end through an opening 64, flow downwardly past the superheating tube bank 50, through a duet 68 which extends through the drum 6, frusto-conical plates 65 and 65A funnelling the gases respectively to and from the duct 68, past the steam generating and economiser tube banks 35 and 23, and leave the vessel through an opening 14 at the lower end. External connections to the steam and water drum 6, e.g. for a level gauge and for balancing pipework between drums when operating boilers in parallel, may be made without passing through the wall of the pressure vessel itself.

Title: Improvements in and relating the anodic coating of aluminium and aluminium alloys
IPC: C25D11/24
Filed: 1932-09-16
Abstract: A sheet or other article of aluminium or an aluminium alloy having thereon an oxide film or coating produced by chemical or electro-chemical means is further treated to form thereon a semi-colloidal layer of the sulphide or arsenite of lead or antimony and is thereafter treated, for example, by agitation in a liquid, in such a way that the semi-colloidal layer is broken through in an irregular manner.  In an example, the oxide-coated article is first dipped in a solution of an organic red dye.  It is then washed and immersed in a 20 per cent. solution of lead acetate at 65-80 DEG  F. It is then immersed in a 50 per cent. solution of ammonium sulphide at 65-85 DEG  F. and oscillated therein.  It is finally washed and gently brushed, leaving a pattern of dark brown on a red background. The dyeing may be effected after formation and local removal of the semi-colloidal film.  The local removal of the film may be effected in several stages with intermediate treatment by different dyes.  The lead sulphide finally remaining may be treated for modification of its colour, for example, by immersion in a 1 per cent. solution of chromic acid.  The production of a variegated pattern in black, gold and red is described.  The semi-colloidal films may be produced by successive immersion of the article in solutions of lead acetate and sodium arsenite, or in solutions of a salt of antimony and of a soluble sulphide or arsenite.  Patterns of different scale may be produced by these means.  Specifications 290,901, 290,903, [both in Class 41]; 378,521, 391,903; 395,390 and 396,743, [both in Group XXXVI], are referred to.

Abstract: 1,048,656. Testing cigarettes. K. KORBER. Aug. 13, 1962 [July 5, 1962], No. 25780/62. Divided out of 1,048,653. Heading A2C. In a cigarette producing machine in which wrappers are provided around double length filters interposed between the cigarettes arranged end-to-end a device provides advance mutilation or marking of faulty wrapper sections, while still in strip form, to ensure definite rejection at a late testing stage of the cigarettes which receive the wrappers. The wrapping material is supplied as a continuous strip from a reel 124a and is guided by pulleys 126a to pass between suckers 71, 71a and perforation rollers 79a, 79b. When reel 124a expires and the end of the strip passes through the device, a lamp 74a illuminates a photoelectric cell 75a which sends an impulse to control apparatus 77, 82 and thence to switching devices 78, 83 which cause magnets 73, 84 respectively to lower sucker 71a and bring the perforation rollers together to join and perforate the double wrapper layer at the connecting point. Reel 124 then proceeds to supply the strip and a fresh reel 124a placed in position for the next charge. Joins in any reel are detected by scanning cells 80, 80a in which case only the perforating rollers 79a, 79b are moved and the suckers remain stationary.

Title: Improvements in and relating to static inverters
IPC: H02M7/515
Filed: 1963-06-28
Abstract: 998,119. Inverting. UNITED AIRCRAFT CORPORATION. June 28, 1963 [Oct. 30 1962], No. 25803/63. Heading H2F. The invention relates to inverters which have one or more main static switching devices, which may be semi-conductor controlled rectifiers or gas tubes, and a commutating arrangement including at least one capacitor and control static switching device. According to the invention the commutating capacitor is charged independently of the direct current source. In Fig. 3, the inverter circuit comprises transformer 22 whose centre tapped primary 20 is connected to a direct current source 18 through a smoothing inductance 28 and two semi-conductor controlled rectifiers 10, 12. The commutating arrangement includes control device 14 and commutating capacitors 34 and 36 which are charged by rectifiers 46, 48 supplied from the winding 42 of the transformer. In operation the controlled rectifiers are fired in the sequence 10, 14, 12, 14, 10 and so on. A conventional commutating capacitor 38 is connected between the anode of controlled rectifiers 10 and 12 to commutate the inverter if the commutating arrangements just described fails to work. In another embodiment (Fig. 2, not shown), there is no extra winding and rectifier circuit. The junction of capacitors 34 and 36 is connected through a diode and resistance or inductance to the negative line of the supply, so that when controlled rectifier 10, is fired and the anode of controlled rectifier 12 reaches twice the supply voltage, then capacitor 36 is also charged to twice the supply voltage. Consequently a smaller capacitor is required than in the known arrangement (Fig. 1, not shown), in which the junction point of capacitors 34 and 36 is joined to the centre tap of winding 20. In a further embodiment (Fig. 4, not shown), the current pulse which occurs in the smoothing inductance 11 when the controlled rectifiers 10, 12 are fired is used to induce a voltage in a secondary winding on the smoothing inductance. This voltage is rectified and fed to the junction point of capacitors 34, 36 to charge them.

Filed: 1954-09-08
Abstract: 805,463. Liquid, gaseous or pulverulent fuel burners. FUEL FIRING, Ltd., and WEBB, E. F. D. Nov. 2, 1955 [Sept. 8, 1954], No. 26078/54. Class 75(1) [Also in Group XXIX] For varying the flow of fluid through a conduit e.g. a burner, a series of radially disposed juxtaposed flexible vanes mounted at their leading and trailing edges transversely of the direction of fluid flow in the conduit are operably controlled during the fluid flow for varying the curvature of the vanes. The arrangement shown in Figs. 1 and 4 comprises a series of resilient radial vanes 11, attached at their trailing edges to pins 21 mounted in ball and socket joints 22 in a housing 20 and at their leading edges to radial arms 10 of a spider 9 attached to a slidable sleeve 7. The curvature of the vanes 11 is altered by moving the sleeve 7 towards or away from the burner mouth by fluid pressure acting on pistons 14 attached by rods 13 to a plate 12 connected to the rear end of the sleeve 7. 'The vanes 11 on movement in the direction of arrow A, Fig. 4, are bent from the form shown at B to the form shown at C thus varying the area of discharge of secondary air and altering from B to a the angle at which the air is discharged into the cambustion zone. The air supply to the burner enters through openings 25 in a casing 23 attached to the furnace wall 24 and is divided into two streams one stream, the primary air, passing through slots 8 in the sleeve 7 and slots 5 in an inner sleeve 1 to a position where it is deflected towards the burner tube 2 by a conical flange 6 on the sleeve 1 and the other stream, the secondary air, passing between the vanes 11. Axial movement of the sleeve 7 also varies the primary air supply to the cambustion zone by altering the alignment of the slots 8, 5. The housing 20, slidably mounted within the casing 23, is supported on a tube 18 attached to a back plate 17 normally held against the casing 23 by suitable locking means so that when the locking means are released the housing 20 can be drawn into the casing 23. A fuel control valve 27 mounted at the rear of the sleeve 1 is operated by a control lever 30 which lever when in the operative position engages a collar 3 on the tube 2 to lock the tube 2 in position and when in the inoperative position shuts off the fuel supply and disengages the collar 3 so that the tube 2 can be removed. A pre-set primary-secondary air ratio can be effected by rotating the sleeve 1 by a handle 32 to vary the alignment of the slots 8, 5. In a modified arrangement, shown in Fig. 5 a set of fixed radially disposed vanes 11a are aranged at the forward end of the sleeve 1 and the adjustable vanes 11 are aranged around the fixed vanes 11a.
