Title: Welding
IPC: C25B9/19
Filed: 1974-07-22
Abstract: 1475549 Controlled electrolytic hydrogen/ oxygen production Y BROWN 22 July 1974 [20 July 1973 3 Aug 1973 2 May 1974]  32283/74 Heading C7B [Also in Division B3] A mixture of hydrogen and oxygen useful for producing a neutral oxy-hydrogen welding flame is produced by electrolysis of water in an undivided cell provided with means for progressively reducing the electrolysis current in response to increasing gas pressure in the cell. As described, cells 70 (for main electrolysis) and 71 are combined in a common housing and inter-connect via a passage between walls 77, 78. The conical electrodes of cell 71 and the terminal electrodes of the bi-polar series in cell 70 are connected in series. Excess gaspressure generated in cell 70 causes the electrolyte level in cell 71 to be lowered (by passage into reservoir 81) whereby less area of electrodes 74 is immersed, providing automatic monitoring and regulation of the rate of electrolysis. 82 is a pressure relief valve. Electrodes 73 are mounted in an insulating tube leaving perforations for passage of electrolyte and gas. A flash-back arrester 83 is provided in the pipe connecting with burner 80. A porous plug, capillary tube or water-bath arrester may be used. An auxiliary generator for separate H 2  or O 2  generation may be provided for producing an oxidizing or reducing flame if required. The burner 80 may include electrodes for arc welding using atomic H/O mixture. The oxygen in the mixture may be separated magnetically or the hydrogen may be stored by absorption in Pd. The electrolyte may be KOH, using A.C. or D.C. current.

Title: Process for recovering sulphur compounds of ammonia in the form of salts from gas mixtures containing sulphuretted hydrogen and ammonia
IPC: C01B17/16
Filed: 1925-12-23
Abstract: 268,024. Siemens Akt.-Ges., F., and Bõhr, H. Dec. 23, 1925. Purifying processes.-Gases containing sulphuretted hydrogen and ammonia are purified by bringing the gas, in the presence of oxygen, into contact at elevated temperature and at ordinary or higher pressure with a catalyst consisting of at least two metals, one being iron, nickel or copper and another tungsten, vanadium or chromium, whereby the sulphur dioxide produced by the oxidation of the sulphuretted hydrogen combines with the ammonia. The metals may be used as an alloy in the form of a coating or as a wire or netting which may be heated bv the passage of an electric current. The resistance alloy of nickel, iron and chromium may be used for this purpose. For the metals may be substituted the corresponding oxides, or salts producing oxides, such as the carbonates, nitrates or oxalates. The gases, which may be heated instead of the catalyst, are preferably freed from tar before use, a heat exchanging apparatus being used to reheat the tar-freed gas. The mist of ammonium salts is condensed at a temperature above the dew-point by electric means or by washing or filtration.

Title: Piezo igniters
IPC: F23Q3/00
Filed: 1973-07-09
Abstract: 1432685 Piezoelectric igniters BRALIN AG 9 July 1973 [6 Sept 1972 19 Jan 1973] 32629/73 Heading H2A In a piezoelectric igniter, a hammer is normally held at rest in a position where it forms part of a closed magnetic circuit which includes a permanent magnet. In the embodiment shown, the hammer comprises a permanent magnet 9 and a pot-shaped yoke 8, and is normally held against a fixed yoke 10. If, however, a cap 15 is pressed, the magnetic forces acting on the hammer are eventually overcome, and a compressed spring 18 is then free to drive the hammer on to a piezoelectric unit 2. A spring 19 returns the hammer after impact. In the embodiment of Fig. 2 (not shown), the cap (15) is magnetic and surrounds a return spring (31); in addition, a compression spring (18) is joined to both the cap and the hammer. In the arrangement of Fig. 3 (not shown), a yoke hammer (27) normally completes a circuit comprising a permanent magnet (26) and an L- shaped yoke (25), but if a leaf-spring (29) is pushed at one end the yoke hammer is eventually released and is propelled on to a piezoelectric unit (2). The hammer is returned to its rest position by stray lines of flux in the magnetic circuit. In the system of Fig. 4 (not shown), a compression spring (66) acts on a pressure transmission element (63) to release a permanent magnet/yoke hammer (59, 58/68) from a fixed yoke (60) when a cap (67) is pressed. In that of Fig. 5 (not shown), the hammer comprises a ring magnet (72) and a pair of yokes (73, 71), and is normally held against a fixed yoke (74), but a cap (77) and spring (76) are operable to cause the hammer to strike a piezo unit (53).

Abstract: 1, 066, 517. Electrophysical measurement. F.W. BELL, Inc. Aug. 2, 1965 [Aug. 13, 1964], No. 32899/65. Heading G1N. The invention relates to electromagnetic non- destructive testing apparatus using a Hall plate detector, for e. g. detecting flaws, measuring thickness, or contour following. Several probe constructions are illustrated Figs. 3, 8, 10, 11 (not shown); in Fig. 8 astatic magnetizing coils are used, so that there is zero flux at the Hall plate in the absence of a  test specimen. Measurement may be made in terms of the amplitude of the Hall plate signal, and this may be summed with a voltage derived from the coil drive (representing the magnetizing field), to remove the magnetizing component from the resultant field signal, leaving the amplitude of the reaction component Fig. 12 (not shown). Alternatively, measurement may be made in terms of drive-oscillator-frequency by comparing the output signal with a reference voltage, and using the error signal due to variations in the test piece to control the oscillator frequency to restore a null output.

Abstract: 1,093,914. Deflecting propulsive jets. ERNST HEINKEL A.G. Aug. 2, 1965 [Aug. 8, 1964], No. 32928/65. Heading B7G. [Also in Division F1] An aircraft jet propulsion engine having an after-burner with mechanically controlled jet deflecting apparatus has the deflecting surface cooled, when in the deflecting position, by water injected into the after-burner chamber. The engine 1 has a rigidly attached after-burner 2 with a bevelled end wall 3 which co-operates with a cowl member 5 mounted on a fixed pivot 4 and formed with a propulsion nozzle 14. The cowl may be swung forwardly about pivot 4 to partially enclose after-burner 2 whereby nozzle 14 is aligned with engine 1 for forward propulsion of the aircraft in which the engine is installed. When in the deflected position shown the hot gases impinge on surface 8 and deposit an amount of unburnt fuel. To cool the deflecting member and also to cause burning of the unburnt fuel, water is discharged into the after-burner and the deflecting member through fixed nozzles 7. Another arrangement is described in which the deflecting member comprises a plurality of pivoted sections. There is a prior art reference to injection of cooling air into the jet deflecting apparatus.

Abstract: 429,273. Spray carburetters. POLLAK, L. O. A., 61, Victoria Road, Whalley Range, Manchester. Nov. 25, 1933, No. 32985. [Class 7 (iii)] Within the casing a is axially moved by manual means a piston h connected by an extension h<1> to a pear-shaped member i coacting with a choke tube n to serve as a throttle valve. The piston is bored to receive a fixed fuel pipe e mounted in a part d to which fuel is supplied from a pipe f through an interchangeable nozzle g mounted in a securing bolt f<2>. Packing is provided at k. The largest diameter of the pear-shaped body is greater than the diameter of the throat of the choke tube, and radial fuel discharge passages lead from a recess in the member i to a point rearwardly or on the air inlet side of the part of the largest diameter. When the throttle is opened, the air sweeps past the fuel outlets at an angle of from 30 to 45‹. The throttle is actuated through links o, and a stop r limits the inward movement to provide for slow running.
