Abstract: 837,738. Gas turbine plant. SZYDLOWSKI, J. Dec. 19, 1957 [Jan. 8, 1957], No. 39552/57. Class 110 (3). [Also in Group XI] A centrifugal liquid fuel atomizer device for a gas turbine annular combustion chamber 1 having a radial combustion zone 2 comprises a rotatable distributing wheel 15 formed on its periphery with spaced injection holes 20 opening into a cavity 22 formed in said wheel and a tube 23 coaxial with the axis of rotation for supplying the cavity 22 with fuel and provided with means for forming at its outlet a uniform fuel film coaxial with said axis, said cavity 22 being connected with the injection holes 20 through one or more channels formed at the periphery of the cavity 22. As shown, a plurality of radial ducts 17 connect the cavity 22 with respective injection holes 20 and these latter are inclined alternately to one side and the other of a plane perpendicular to the axis of rotation. In another embodiment described in Figs. 1-3 (not shown), the radial ducts are replaced by an annular peripheral channel of rectangular cross-section running round the cavity 22 and the injection holes open into the channel at points spaced from the bottom of the channel. The tube 23 is formed over its inner surface with splines 25, Fig. 5, which merge at their ends into an enlarged smooth surface 26 adjacent the tube outlet so as to form the fuel into a uniform film coaxial with the axis of rotation and cross webs may be provided in the tube inlet downstream of a fuel feeding nozzle so as to impart rotary motion to the fuel fed through the nozzle. The cavity 22, formed of a blind bore 18 ground or polished, is closed by a steel sleeve 21 fitted into the bore and welded to the wheel 15, which in turn is welded at 16 to the central shaft 3 of the gas turbine. The fuel supply tube 23 extends coaxially through the sleeve 21 being guided in the bore 18 by a radial flange 24, the engaging surfaces being ground to fit as also the inner peripheral surface of the wheel and the engaging outer surface of the flange, for the removal of the tube and, to ensure perfect sealing, rubber rings 27 associated with discs 28 are maintained within the sleeve 21 by circlips 29.

Abstract: 807,039. Pipe couplings. MAJOR ALUMINIUM PRODUCTS (B.C.) Ltd. Dec. 31, 1956, No. 39664/56. Class 99(1). In a pipe coupling particularly for air lines, a housing 12 receives pipes 10, 11 each having a pair of oppositely extending lugs 17 received in grooves 25 in the housing each groove being closed off by an abutment at one end to limit movement of the lugs in one direction and open at the other, disengagement being prevented by adjustable locking means and the pipes 10, 11 having limiting movement with respect to the housing about axes passing through each of the pairs of lugs and having sealing means to prevent leakage. Each pipe 10, 11 has a reinforcing sleeve 13 at the end inserted into the housing through which screw-threaded shanks 16 of the lugs 17 are passed to be engaged by nuts 18. The axes formed by the lugs 17 on the pipes 10, 11 are transverse to each other. The housing 12 may be formed with a tapped outlet and internal shoulders 21b, 21c which are of different radial heights limit the movement of the pipe and as shown permit greater movement of each pipe about an axis passing through the lugs than at right angles thereto. Instead of having discontinuity between the higher and lower portions, the internal surface may be elliptically shaped. Recesses 22 are formed within the housing to receive V-shaped sealing gaskets 23 which seals the pipe and housing against outward pressure but permits movement. The housing 12 has extensions 24 which receive lugs 17 in arcuate grooves 25 which are located oppositely. The locking means is provided in one of the grooves 25 of each pair of oppositely disposed grooves and comprises a bolt 29 which when tightened blocks the groove so that the lug contained cannot disengage. The bolt 29 is spaced from the abutment preferably at a right angle so that the pipes can be rotated by a limited amount, the lugs remaining in the grooves. In a modification, Figs. 5, 6 (not shown) the housing is curved and is in the form of an elbow coupling.

IPC: G05F1/45
Filed: 1968-08-21
Abstract: 1,201,120. Control circuit for domestic heating equipment. STANDARD TELEPHONES & CABLES Ltd. 21 Aug., 1968, No. 39923/68. Heading H2H. A circuit arrangement for regulating A.C. supply to a load includes a trigger circuit which delivers a control signal to a controlled switching element, and a variable element which can inhibit the trigger circuit for one or more whole cycles of the supply. As shown a transistor T1 receives negative to positive zerocrossing pulses through a capacitor C 1  and conducts to fire a second transistor T2 so that potential from P is applied through resistor R1 to charge a capacitor C biasing T 1  and thus T 2  to become hard turned on. Resistor R 1  and capacitor C are such that C is fully charged in one half cycle and the transistor T 1 , and thus transistor T 2  ceases to conduct. When T 2  conducts the potential P is also applied to a circuit including a transformer L whose secondaries 5, 6 are pulsed to switch controlled rectifiers S 1 , S 2  whenever the transistor T 2  starts or ceases to conduct. A variable resistor R v  in circuit with diodes D 1  and D 2  and capacitor C controls the discharge of the capacitor to inhibit whole cycles of operation. R v  may be controlled by heat or light or may be connected to a Zener diode for voltage setting (Fig. 3, not shown). The transformer L may have its two secondary windings connected to control a single thyristor which forms the diagonal element of a rectifier bridge in series with the load (Fig. 4, not shown).

Title: Cooling device for a semiconductor component
IPC: H01L23/40
Filed: 1977-09-26
Abstract: The cooling device, especially for a thyristor at any potential desired, has at least one cooling body which is in thermal contact with the semiconductor body and through which a liquid flows continuously. It is known to remove the lost heat in semiconductor elements by means of air or oil. A suitable cooling medium with better properties would be water, but hitherto the problems of electrolysis arising from the use of water have not been manageable. The cooling device is designed to be suitable for water as a cooling medium. The cooling body therefore consists of a cooling plate (2) and a distributor plate (1), the cooling plate (2) being provided with a groove (3) for the cooling liquid to flow through. The distributor plate (1) has, at the inlet and/or outlet point of the cooling liquid, a chamber (10, 11) which has a larger cross-section than the groove (3). Arranged in this chamber (10, 11) there is an electrode (12) which consists of a readily conductive material which is chemically resistant to the cooling medium. <IMAGE>

Abstract: 1286541 Roasting pyrites FARBENFABRIKEN BAYER AG 18 Aug 1969 [20 Aug 1968] 41080/69 Heading C1A Pyrites is roasted in a rotary kiln with a deficiency of oxygen such that all the pyrites is converted to iron oxide by only part of the sulphur to SO 2 , the remainder being removed as elemental sulphur, and burning the sulphur in a post-combustion chamber, the heat produced in the kiln and/or the post combustion chamber being used to generate steam. Oxygen as air is supplied to the kiln at the end from which the roasted ore is discharged and is also distributed over the length of the kiln by means of supply pipes whose walls are formed of helically or longitudinally wound boiler tube. The supply of air is desirably regulated so that the roaster gas contains 8-16% SO 2  and also so that 1 mole SO 2  and 1 mole S is formed per mole of pyrites. The steam is generated by means of cooling fingers projecting into the kiln through which water is passed. The rate of steam generation is suitably controlled so as to maintain the reaction temperature between 650‹ C. at the inlet and 950‹ C. at the outlet. The elemental sulphur may be burnt to SO 2  in a combustion chamber with cooled tubular walls to maintain a temperature of 700-1100‹ C. The SO 2  may then be cooled so rapidly to 250-350‹ C. as to avoid formation of SO 3  in a chamber containing steam generator and superheater tubes, the coolant temperature being 200-300‹ C. The SO 2  may be purified for SO 3  and H 2 SO 4  manufacture.

Abstract: 1521275 Measuring mass flow-rates ITT INDUSTRIES Inc 10 Oct 1975 [11 Oct 1974] 41667/75 Heading G1N Apparatus for determining the mass flow of each of the two constituents of a liquid mixture through a conduit 473, Fig. 1, comprises a fluid densitometer 472, measuring the average density, and a rotor type flowmeter 402, measuring the volumetric flow-rate. The pulse train produced by the latter is gated as described below in accordance with the known densities of the two constituents to produce on counters 411, 415 indications of the total mass flow of each constituent. The apparatus is described with reference to a mixture of oil and water. The gating circuit 400 comprises an integrator 427, Fig. 2, connected to the terminals of a voltage source 422 via a changeover switch 424, whose output is compared at 428 with a high level voltage dependent on the density of the water, and at 429 with a low level voltage dependent on the density of the oil. When the integrator output reaches the appropriate voltage level switch 424 changes over, producing a triangular output waveform 475. This is compared at 430 with the voltage signal from the densitometer 472 to produce a pulse train 478 whose pulse duration T w  is equal to the time that the triangular wave 475 exceeds the densitometer signal. It is stated that this time is proportional to the percent by weight of water in the fluid mixture, and the time Tt between pulses is proportional to the percent by weight of oil. The frequency signal from flowmeter 402 is gated by switch 408, which is controlled by the pulse train 478, to feed counters 411, 415. The low level detector 429 incorporates a thermistor 421 to modify the low level voltage, dependent on the density of the oil, in accordance with the temperature of the oil in the liquid mixture. Alternative arrangements are described for gating the pulse train from flowmeter 402 in accordance with other relationships between the densities of the mixture and its two liquid constitutents.
