Abstract: 1530146 Gas turbine combustion chambers UNITED TECHNOLOGIES CORP 12 Dec 1975 [18 Dec 1974] 51084/75 Heading F1L [Also in Division F4]  To reduce NOx emissions from a combustion chamber, e.g. of a gas turbine engine, a pilot combustion zone is established and into the products therefrom is introduced a rich fuel/air mixture, thus vaporizing the fuel, main combustion air then being added to the mixture to raise its oxygen content sufficiently for self-ignition to occur. In one arrangement, air from the engine compressor flows via swirl vanes 30 into an annular duct 28 where a substantially stoichiometric quantity of pilot fuel is added by nozzles 32. The swirling pilot mixture then flows through perforated flame stabilizing baffle 24 into a pilot combustion zone 22 where it is ignited by ignitor 34. To the downstream region of zone 22 is added via radial ports 44 a rich fuel/air mixture derived by the injection through secondary nozzles 42 of at least three times the stoichiometric amount of fuel into annular air duct 40. The pilot combustion products vaporize the secondary fuel but selfignition does not occur until the mixture enters the main combustion chamber 18 where the oxygen content is raised by the addition through swirlers 46 of main combustion air. In a modification Fig. 2 (not shown) corrugations (82, 88) at the  downstream ends of the duct walls assist mixing. Figs. 3, 4 (not shown) illustrate modified fuel injectors.

In the manufacture of an electrode comprising "a titanium support" and an electro-deposited coating of "a platinum metal" thereon, at least the outermost layer of the platinum metal coating is electro-deposited from a plating bath which contains an admixture of an aliphatic polybasic hydroxy acid, e.g. citric acid. "A titanium support" means a support consisting of Ti alone or an alloy based on Ti and having anodic polarization properties similar to those of Ti. Examples of suitable Ti alloys are Ti with Zr, Pt, Rh, Ir, Nb or Ta. "A platinum metal" means Ru, Rh, Pd, Os, Ir, Pt or an alloy of at least two of these metals. The titanium support may be electroplated with a platinum metal from a conventional bath before being electro-plated using the bath containing the admixture. Electrodes produced by the process may be employed as anodes in electrolytic cells wherein Cl 2 , hypochlorites or chlorates are produced by the electrolysis of alkali metal chloride solutions, as anodes in cells for the electro-dialysis of brackish water and as anodes for the cathodic protection of iron and steel structures immersed in sea water. In an example, a sheet of Ti is etched in HC1 and then electroplated with Pt from a bath containing HC1, chloroplatinic acid and citric acid using a current density of 0À3 A/dm<SP>2</SP> and a bath temperature of 70‹C. During plating, the Ti sheet is moved in a circular path within the bath.

Abstract: 1,246,292. Discharging different kinds of articles from a conveyer. L. G. DAHLQUIST. 1 Nov., 1968, No. 51926/68. Heading B8A. [Also in Divisions B2 and G1] In a method of sorting objects of two or more kinds which are fed in a stream along a feeding path where the stream is divided into two or more different streams, each of which only contains objects of the same kind, a plurality of sorting means 3 are mounted on an endless conveyer 2 and moved synchronously with the objects (not shown) to be sorted, each sorting means being displaceable in a lateral direction with respect to the feeding path of the objects from a laterally idle position along the path, each object being allotted a sorting means of its own, in which the occurrence of a certain property of the objects is detected, and in which objects in respect of which this property has been detected are laterally transferred a predetermined distance by means of the allotted sorting means. As described, the objects are coloured and plain bottles which are to be sorted according to colour. They are fed on to an endless conveyer 1 and are uniformly spaced by a feed screw 9. The coloured bottles cause a photo-electric gate 7, 8, to energize an electromagnet 5. This attracts an arm 6 which latches on to a guide rail 4. The latter is spaced progressively nearer to the conveyer 2 in the downstream direction of the latter. Thus coloured bottles are progressively deflected to the far side of the conveyer belt 1 while plain bottles remain in their original lane. There may be a single conveyer in place of the two separate conveyers 1, 2. The ratio between the speed of deflection and lateral conveyer speed is preferably 1 : 5 but may be in the range 1 : 2 to 1 : 50. The sorting belt 2 may alternatively be mounted above the belt 1. The stream may be divided into more than two streams in dependence on different properties of the bottles. Different kinds of objects may be displaced laterally in opposite directions.

Abstract: 1504557 Wear adjusting in drum brakes DBA SA 18 Dec 1975 [23 Jan 1975] 51926/75 Heading F2E Relative rotation of two threadedly engaging parts 42, 34 of an extensible strut connecting two shoes is effected by relative axial movement of the two parts 72, 48 of a control member connected to one shoe and, through a one-way coupling 54, 56, to part 42 of the strut. As shown, ratchet teeth 54 formed on the nut 42 are engaged by pawl 56 carried by a ring 60. The latter is now rotatably located in a slot 62 in a sleeve 48 joined to a connecting piece 72 by a pin-in-inclined-slot coupling 52. Piece 72 and the screw member 34 are respectively pivotally connected to one shoe and a handbrake lever on the other shoe so that when the shoes separate, piece 72 moves relative to nut 42, and coupling 52 rotates sleeve 48 to cause the panel to ratchet over teeth 54; a spring 84 frictionally prevents rotation of the nut during such movement. If the pawl has jumped a tooth because of wear return movement of the shoes rotates the nut to increase the strut length. The ratchet may be formed on the screw rather than the nut and the strut may be connected the opposite way round between the shoe and handbrake lever. Spring 84 may be replaced by a friction washer.

Abstract: 1,129,961. Voltage ratio measurement. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec.15, 1965 [Dec.29, 1964], No.52686/64 Heading G1U. Apparatus for indicating the ratio of the amplitudes in two different parts of the cycle of a repetitive signal comprises an amplifier 19-25 having a. g. c. to hold constant its output during the portion of the cycle having the larger amplitude, and a circuit to derive the difference between the amplifier output during the portion of the cycle having the lower amplitude, and half the peak-to-peak output. The signal is derived from an infrared pyrometer and produces at the output of amplifier 19 a two level step waveform Fig. 2 (not shown) having a peak-to-peak amplitude V1, and a lower amplitude V2. This signal is fed to positive and negative D.C. restorers C2, D1 and C1, D1 the outputs from which are fed to two resistors R1, R2. If the values of these resistors are suitably chosen, the current in meter M is proportional to V 1 /2 - V2 which, if V 1  is maintained constant by the a. g. c. action, is proportional to the required ratio. Modified D.C. restoring circuits giving difference signals which swing above and below zero are given in Figs. 4, 5 (not shown) and further circuits in which the signals swing about a mean D.C. level are given in Figs. 6, 7 (not shown). In order to compensate for variations in the peak-to-peak output from the amplifier the backing off circuit of Fig. 3 (not shown) may be employed in which a capacitor (C3) is charged to the voltage V 1 , and a portion of this is applied from a potential divider (R3, R4) to the meter.

With a main valve 3 and a pilot valve 11 in the closed position shown the gas flowing in the direction of the arrow 2 passes through baffled openings 5 in the valve 3, a chamber 20 and an orifice 8 into chambers 9 and 26. The gas acts on the front face A of the valve 3 tending to unseat it and is opposed by the gas in chamber 20 and differential piston areas in chambers 26 and 9 as well as a spring 28. When a solenoid 32 is energized to open the pilot valve 11, the chambers 9 and 26 communicate with atmosphere via a filter 13 and a chamber 22 opposed to chamber 9 remains open to atmosphere through a filter 23 so that the valve 3 unseats and gas flows past ribs 17 to an outlet 34. The chamber 26 may be supplied by leakage past differential piston area 24 instead of by a passage 27 in which case a dash-pot action is provided. The valve will continue to function should the spring break. In a modification the main and pilot valves are both normally open in which case the spring 28 is disposed in chamber 22. The main valve is supported on carbon bearings 4, 15, 18, 25 appreciable wear of which does not affect the valve operation due to the substantial difference in the opposing areas on which the gas acts.
