IPC: F23R3/30
Filed: 1951-10-16
Abstract: 709,452. Generating combustion products under pressure. NAPIER & SON, Ltd., D. Oct. 15, 1952 [Oct. 16, 1951], No. 24160/51. Class 51 (1). [Also in Group XI] Liquid-fuel combustion apparatus particularly for a gas turbine plant comprises one or more fuel distributing members C, Fig. 1, for maintaining layers of liquid fuel on at least some of the surfaces of a series of annular, radially spaced, substantially coaxial bodies B, B1, and which are rotatable about an axis coincident with or adjacent and parallel to the axis of the bodies B, B1 and comprise a radially extending fuel passage leading to a number of radially spaced fuel delivery nozzles C2 or the equivalent for delivering fuel on to the said surfaces, and means such as an air compressor for producing a flow of combustion air over the bodies B, B1. In the apparatus illustrated in Fig. 1 two fuel distributing conduits C are carried by the rotary inner wall A1 of an annular combustion chamber A2 at a point to the right of a diaphragm D extending across the interior of the wall A1, along which fuel flows axially from a supply point to the right of the conduits C to be discharged by centrifugal action through the latter. The fuel thus receives heat from and cools the wall Al and any fuel vaporized within said wall may escape through apertures D1 in the diaphragm D and may be led into the combustion chamber A2 through further holes in the wall A1 upstream of the conduits C. Each of the latter 'is formed with discharge orifices C3 and tubular nozzles C2 having metering inlet orifices C4, Fig. 3, or with either orifices C3 or nozzles C2. The bodies B, B1 are of oval cross section and are formed as incomplete annuli to avoid distortion due to thermal expansion, being supported from the outer wall A of the combustion chamber by radial bars A4, the bodies B1 being disposed downstream of the bodies B and in the paths of the air stream passing between the latter. Alternatively each of the bodies B, B1 may be of streamline cross section or of V-section so as to provide a sharp upstream edge and a concave rear surface. According to the Provisional Specification the rotary fuel distributing member or members may pass through one or more circumferential slots in a stationary inner wall of an annular combustion chamber.

Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: B01J37/20
Filed: 1949-09-22
Abstract: <PICT:0697227/III/1> In the autofining of petroleum hydrocarbons the catalyst, a mixture of the oxides of cobalt and molybdenum deposited on or incorporated with a support (preferably alumina), is pre-treated with hydrogen sulphide or hydrogen sulphide-containing gases. Conveniently the hydrogen sulphide-containing gases obtained in the autofining process may be used.  The treated distillate may be cooled at plant pressure to separate the recycle gas rich in hydrogen and containing traces of hydrogen sulphide.  The liquid product may then be stabilized by being reduced to atmospheric pressure to release the bulk of the hydrogen sulphide, the remainder of the hydrogen and a proportion of light hydrocarbons. This gas may contain approximately 50 per cent hydrogen sulphide, and if desired this may be recovered and used in substantially pure form.  The autofining process may be operated by allowing the pressure to rise to an equilibrium pressure at which the hydrogen evolved equals the hydrogen consumed.  Two reactors may be used in the process, the hydrogen sulphide-containing stabilizer gas being passed through a reactor immediately after regeneration while the catalyst is still hot.  As shown, the feed is introduced through line 10 through a preheater 11 to one of two reactors 12 held under autofining conditions of temperature and pressure.  The product is passed through line 13 and cooler 14 to the separator 15 from which recycle gas is removed through line 16 and mixed with preheated feed.  The liquid product from the separator 15 is passed to the stabilizer 19. The overhead gas is passed through cooler 20 to a separator 21 from which the hydrogen sulphide rich gas may be vented through line 22. The hydrogen sulphide free product is removed from the base of stabilizer column 19 through line 24.  While one reactor is on stream, the other is being regenerated with steam and air admitted through line 25.  As soon as regeneration is complete and while the catalyst is still hot, hydrogen sulphide rich gas is passed through lines 25 and 27 and leaves through line 26.  The reactor is ready to put on stream when the regenerated catalyst in it is sulphided.  The application of the process to the autofining of a wax distillate containing 1.74 per cent of sulphur is described in the example. Specifications 654,152, 663,038, 669,536, 669,552, 669,553 and 697,083 are referred to.

Filed: 1927-09-16
Abstract: 282,629. I. G. Farbenindustrie Akt.- Ges. Dec. 23, 1926, [Convention date]. Pyranthrone dyestuffs.-Vat dyestuffs giving orange dyeings from an alkaline hydrosulphite vat are produced by treating Bz: Bz<1>- diarylpyranthrones with acid condensing agents. When the latter are not oxidizing agents the reduced derivative of the dyestuff is first obtained. In an example, Bz : Bz<1>-diphenylpyranthrone is condensed by means of manganese dioxide in the presence of sulphuric acid whilst cooling, and the resulting dyestuff is separated by pouring into water. It may be purified by means of sodium hypochlorite solution. The same starting material is condensed in a second example by means of aluminium chloride in fused common salt. Oxidation of the resulting hydro compound commences during the operation and is completed by aeration.

Title: Improvements in or relating to a method of building up rails and to the built-up rails formed thereby
IPC: B23K31/02
Filed: 1934-08-27
Abstract: 435,953. Rails. OXWELD RAILROAD SERVICE CO., 230, North Michigan Boulevard, Chicago, U.S.A.-(Assignees of George, H. S.) Aug. 27, 1934, No. 24636. Convention date, Sept. 6, 1933. [Class 104 (ii)] [See also Group XXII] The ends or intermediate parts of new or substantially unworn rails may be built up by first removing original rail metal to form a depressed tread surface and then depositing metal capable of hardening upon cooling from an elevated temperature on a part of the surface and after cooling, depositing such metal on the remaining part, so as to obtain a built-up rail in which the last deposit is the hardest. A rail 13 of weight amounting to 130 lbs. per linear yard and having a depressed area 11 of average depth of 0À02-0À06" at the extreme end and more than three inches in length, e.g. five inches, is first built up by an air-hardening steel such as an alloy steel containing 0À5 per cent of carbon, 0À9 to 1À1 per cent of manganese, 0À9 to 1À1 per cent of chromium and 0À4 to 0À6 per cent of silicon at the portion 16, and is allowed to cool to black heat or atmospheric temperature and a second deposit 17 is then applied, which may extend ¢" back at the outer edge and 2" at the inner edge. The hardness of the deposits after cooling is at least 50 to 52 Scelerescope or 350 Brenell before service or 60 Scelerescope after service. The deposit 17 may be trapezoidal as shown, or triangular, and in the latter case need not extend to the outer side in cases where the rails are lighter, or where greater hardness is to be obtained. Deposition is effected by welding. The Specification as open to inspection under Sect. 91 states also that to avoid large worn areas on rails, new rails may have a part removed to 0À04 to 0À06" and a single deposit of an hardening steel of greater hardness than the rail metal applied corresponding in size to the part 17. This subject-matter does not appear in the Specification as accepted, but forms the subject-matter of Specification 437,248.

Abstract: 1,193,342. Making electrical contact assemblies. TELEFUNKEN PATENTVERWERTUNGS-G.m.b.H. 30 May, 1967 [28 May, 1966], No. 24773/67. Heading B3A. [Also in Division B5] In a method of making an electrical contact assembly particularly for a sliding switch, a plurality of spaced apart wires or strips 1 are simultaneously shaped to form contact elements, a portion of each of which in the same spaced apart position is subsequently embedded in a linking insulating support 2. In one embodiment, wires 1 fed from supply reels are embossed and firmly held in position by dies 3, 4 whereupon plastics is introduced via opening 6 into a mould cavity 5 to form the insulating support 2. After moulding which is by injection or compression, the assembly is advanced and cut off by knife blades 7. In another embodiment (Fig. 2, not shown) wires 1 are first embossed by dies 3, 4 and guided into a mould (8, 9) where the insulating support 2 is formed around the contacts after the dies 3, 4 have embossed and closed on a subsequent set of contact elements. In a further embodiment (Fig. 3, not shown) two opposing rows of contact elements are mounted in a common support 2. An embossed array of wires 1 is fed from dies 3, 4 into the mould (8, 9) to which a second array (1<SP>1</SP>) is fed, preferably from the opposite side, from dies (10, 11). The two sets of contacts are then embedded in a common support 2 and the assembly severed by blades (7, 7<SP>1</SP>). Prior to embedding the two arrays in a common insulating support, each array may first be embedded in a small plastics support whilst it is still positioned in the embossing dies (Fig. 4, not shown).

Title: In-service bushing testing
IPC: G01R27/02
Filed: 1971-04-19
Abstract: 1338445 Measuring capacitance: testing insulation bushings DOBIE ENG CO 19 April 1971 [8 April 1970] 24854/71 Heading G1U A high voltage bushing 10 containing a number of potential-distributing conductive foils is tested whilst "live" by examining the voltage across an impedance connected between one of the outer foils 32 and earth, the impedance being of such a value that substantially all the capacitive and leakage currents I 1  in the bushing flow through but are unaffected in magnitude by, the impedance. The impedance is permanently connected to the bushing and to a socket 40-42 to which a measuring circuit may be connected at any time. In Fig.4 there are two such impedances 80, 81, either of which may be selected according to the test to be made, the unused impedance being short-circuited by the measuring circuit. Measuring bushing capacitance and loss angle In Fig.4 the resistive impedance 80 is used, and an output voltage E 21  is adjusted in magnitude (88) and phase (96) relative to the voltage across the impedance 80 until it balances (120) a reference voltage E s  derived from the high voltage supply E h  to the bushing. The amount of the respective adjustments 88, 96 give direct indications of the bushing capacitance C 1  and loss angle (or power factor). A gain control 104 is pre-set in accordance with the known ratio between the reference voltage E s  and the h.v. supply E h . In a modification Fig.8, (not shown) capacitors (130, 132) perform the functions of resistors 80, 88 in Fig.4. In another embodiment Fig.1, (not shown) a capacitor (34) constitutes the impedance connected to the bushing, and the voltage across it is amplified (48) and compared with a voltage E' s  which is an adjustable fraction of the reference voltage E s . The amount of the adjustment which has to be made to the voltage E' s  to reduce the difference between E' s  and the amplified capacitor voltage E 1  to a minimum is a measure of the bushing capacitance C 1  and the loss angle can be derived from the remaining voltage difference. Testing for partial discharges in the bashing insulation The inductive impedance 81 of Fig.4 is used Fig.7, (not shown) and the power supply frequency components in the voltage across it are suppressed in a high frequency amplifier, the remaining high frequency components due to partial discharges being examined on an oscilloscope.
