The method is intended to provide a bead in which, as shown in Fig. 4, dimension b exceeds a. The weld preparation may be I, V, U, H, or X. Preferably, the filler is 3-20 mm thickness and of width 1-3 times non-consumable electrode diameter. The gas shielding may comprise the inner shield of at least 50% (e.g. 100%) He and an outer shield, preferably of higher specific gravity than that of the inner shield, e.g. 100% A. In the H joint of Figs. 6(a)-(d), (i) a straight polarity TIG arc at both sides, at 4, penetrates the plate centre, (ii) filler 5 is driven into the groove, the filler being elastic or pre-heated (by flame or induction) to fit any curved surface of the weld at 4, (iii) the filler is subjected to TIG arc to provide a deposited metal 5<SP>1</SP>. Such welding is effected on both sides. The filler may be aluminium alloy, of round, oval, square or rectangular cross-section, and may be zinc plated. The electrode may be tungsten containing thorium and may be woven. Example fillers are slit, to facilitate insertion, Figs. 7(a), (b) (not shown); aluminium foil wrapped fibrous or powdery or granular filler, Figs. 7(c) (d) (not shown); aluminium wrapped separate or combined triangular-section-solid and fibrous or powdery filler, Fig. 7(e) (not shown); solid fillers sandwiching powdery, granular or fibrous filler, Fig. 7 (f) (not shown); and magnesium plated aluminium alloy, Fig. 7(g) (not shown). In Figs. 8(a) (b) (not shown), beads of filler material are inserted by MIG welding. In TIG welding, electrode weaving may be transversely of the seam, and, for a wide groove, in and out of the groove. Weaving is preferably 10-100 cycles/min and less than 100 mm width. In tandem TIG welding with two or more electrodes, the distance between electrodes should be 30-200 mm and the time interval for passing of successive electrodes 4-60 seconds. In Figs. 9(a), (b) (not shown), in horizontalvertical position welding, both horizontal and inclined, initial MIG welding effects fusion of the upper portion of the groove and subsequently TIG welding fuses the lower portion. In vertical or inclined vertical position welding, TIG welding may be effected downwardly or, with upwardly effected MIG, upwardly.

Abstract: 1,043,644. Fluid-pressure servomotor systems. ROLLS-ROYCE Ltd. Jan. 30, 1964, No. 4078/64. Heading G3P. A pressure responsive diaphragm 12, Fig. 1 is moved against a datum pressure P d  on its upper surface by a variable input pressure applied through a restriction 20 from a conduit 15, the diaphragm operating a valve member 22 that variably interrupts the flow of fluid from a high pressure nozzle 24 to a receiver 25. The output pressure in the receiver 25 is applied as feedback through a restriction 21 to the lower surface of the diaphragm 12 so that a change of input pressure is accompanied by a related but inverse change of output pressure. The valve member 22 may, alternatively be mounted on a lever actuated by the diaphragm, or a leak valve instead of an interrupter may be lever actuated by the diaphragm. Three inputs 15 with restrictions 20 may be connected in parallel to the chamber below the diaphragm so that the output is functionally related to the sum of the inputs. In another arrangement, in which the output is a function of the difference between two inputs, one input is fed to a device as in Fig. 1 and the output of this device is combined with the other input and fed to a second, similar device the output from which gives the desired function. Figure 6 shows a device in which a servopiston 101 is positioned as a function of Mach No., or P s /P o  where P s  and P O  are pitot and static pressures respectively, the servopiston actuating a valve 120, which may control a jack, and a push rod 124 which may work a trigger for switching on or off a starting cycle mechanism. Pitot pressure acting on a bellows 75 actuates a valve 82 through a lever 76 which is also acted upon by a datum pressure P d  and the output pressure in a line 85. Flow in the output line 85 passes through a needle valve 100 adjusted by the servopiston to provide the input to a device 10f of the kind in Fig. 1. The output from this device acts on a piston 115 bearing against a hinge valve member 113 which controls the servo-piston 101 and is also subject to the action of a piston 114 receiving the output pressure of a device having a valve 82a subject to the effect of static pressure on a bellows 75a.

Title: Removal of sulphur compounds from industrial gases
IPC: C10K1/16
Filed: 1946-02-12
Abstract: <PICT:0620307/III/1> A process for removing sulphur compounds from gases comprises scrubbing with a solution of a reaction product of a phenol and a secondary organic amine in an oil absorption menstruum, heating it to decompose the amine-sulphur complex, distilling off the sulphur compounds and reforming the scrubbing solution for return to the scrubber.  Coke oven gas is scrubbed in a packed tower 1 with piperidine and phenol dissolved in refined creosote oil, absorbing carbon disulphide, carbonyl sulphide, carbon hydrogen sulphide, mercaptans, &c. from the gas which is then scrubbed with water in a superposed tower 4 to remove traces of piperidine by combining with contained carbon dioxide.  If this is not present, hydrochloric or sulphuric acid, ammonium sulphate solution, &c. may be substituted for water.  When the scrubbing medium in tower 1 contains about 8 gm. per litre of organic sulphur, part of the medium is passed through a heat exchanger 14 to a still section 16 and subjected to steam admitted through a pipe 17.  Or all or a part may flow through a heated delay tank 19.  From still 16, piperidine, phenol and compounds thereof, dissolved in oil, return through the heat exchanger 14 and a water separator 25 to the scrubber.  Volatile products from the still are treated in a still 28 with an acid or ammonium sulphate &c. solution, inert, e.g. coke oven, gas also being admitted to assist in evolution of organic sulphur which is separated from condensate containing phenol in a dephlegmator 32.  A piperidine salt solution from still 28 may be subjected to steam in a still 36 to expel phenol and is mixed in a still 39 with piperidine carbonate from scrubber 4 and treated therein with caustic soda or lime to separate free piperidine which is carried off by steam and is passed to still 16.  The process may be used to remove inorganic sulphur compounds such as hydrogen sulphide from gases.  Suitable scrubbing compounds comprise morpholine and its homologues, hydrogenated tar base fractions prepared from a fraction originally including pyridine, quinoline, isoquinoline and may comprise piperidines, pipecolines, lupetidines, copellidines, tetramethyl piperidines and hydro-derivatives of quinoline.  Specifications 617,780 and 618,507 are referred to.  The Specification as open to inspection under Sect. 91 describes also the use of primary amines and weak acids including hydroquinone alamine and inorganic acids, e.g. boric acid, which are displaceable from the amine-acid reaction product by organic sulphur, also the use of water, aliphatic alcohols and ketones as scrubbing medium.  This subject-matter does not appear in the Specification as accepted.
