IPC: F02C3/28
Filed: 1955-09-12
Abstract: 805,786. Gas-turbine plant. HENSCHEL & SOHN G.m.b.H. Sept. 12, 1955 [Sept. 10, 1954], No. 26018/55. Class 110 (3). A gas-turbine plant fed with combustible fuel gas from a gas producer in. which the fuel gas is cleansed and then expanded in an auxiliary turbine to the pressure of the gas turbine combustion chamber and the auxiliary turbine drives an additional compressor which further compresses a controllable part of the air discharged by the gas turbine compressor to the pressure of the gas producer, has a small secondary combustion chamber disposed in front of the auxiliary turbine into which chamber the entire quantity of fuel gas and a controllable portion of the air delivered by the additional compressor is introduced. A compressor 1 discharges air through a control valve 5 and a heat exchanger 6 to the combustion chamber 8 which supplies combustion products to a turbine 18 driving the compressor 1. The exhaust gases from the turbine 18 pass to atmosphere through the heat exchanger 6. A portion of the air discharged by the compressor 1 is branched off at the valve 5 and further compressed by a compressor 10. Part of the air discharged from the compressor 10 is fed as gasifying air to the gas producer 13. The fuel gas from the gas producer is fed, after cleaning, to an additional combustion chamber 15 where it is partly burnt with air taken from the discharge of the compressor 10 through the regulating valve 12. The mixture of fuel gas and combustion products from the combustion chamber 15 is expanded in a turbine 17 and then led to the combustion chamber 8 where the combustion of the fuel gas is completed by air from the compressor 1. The turbine 17 drives the compressor 10 as well as the pumps 21, 25, which supply water to the intercooler 3 and the gas producer 13 respectively. An auxiliary electric motor 28 may also be provided. The gas turbine 18 also drives an electric generator 29.

Title: Improvements in and relating to means for automatically varying the volumetric capacity of combustion chambers for internal combustion engines and compression ignition engines
IPC: F02D15/00
Filed: 1949-10-11
Abstract: 675,984. Cylinders. HUMPHREYS, I. B. Oct. 11, 1949 [May 11, 1949], No. 26074/49. Class 7(ii) In apparatus for automatically varying independently the volumetric capacity of each combustion chamber of an internalcombustion engine to maintain the pressure in the chamber below a predetermined degree irrespective of the load conditions, comprising a movable element such as a piston D, forming part of the chamber wall and arranged with its outer face in contact with a body of liquid, for example, oil, confined within a compartment E, which has an outlet normally closed by a valve 17 mechanically independent of the piston D and loaded so that when the pressure in the chamber reaches the predetermined degree the valve will automatically open and permit the liquid to escape substantially freely without opposition from the compartment E and allow the piston D to be moved by the pressure in the chamber away from its normal position forming part of the chamber wall, the compartment E is provided with a liquid supply, through a conduit 15 for example, so that the cylinder is kept full of liquid and when the chamber pressure falls below the predetermined degree the piston D will be moved by the liquid towards its normal position forming part of the chamber wall. The engine cylinder head 2 has an opening 3 that communicates with a cylinder 4 attached to, or integral with, the head, the cylinder 4 housing the stepped piston D the enlarged part 7 of which is contained in but spaced from the walls of the compartment E that is a con-. tinuation of cylinder 4. An orifice in the head of the compartment E is closed by the ball valve 17 which is adjustably spring- loaded; when the valve 17 is lifted it places the compartment E into communication with a receptacle F that is open at the bottom through a conduit 20 to the engine crankcase or other liquid reservoir The cylinder 4 has a connection 13 with the engine crankcase to provide an outlet for any gases escaping past piston D whilst the compartment E is supplied with oil or similar liquid from the engine lubricating pump or a separate pump through conduit 15. The piston D incorporates a flange 9 which when in contact with a flange 10 on the cylinder 4 defines the innermost position of the piston. In a modification, the ball valve is replaced by a poppet-type valve and the piston flange is dispensed with, the enlarged part of the head being arranged to abut a flange on the cylinder in order to define the inner position of the control piston, which latter feature, in conjunction with an additional stepped part on the piston head ensures a more satisfactory dashpot action of the piston, which latter may be replaced by a diaphragm.

Title: Improvements in or relating to circuit arrangements for increasing the traffic capacity in telephone systems
IPC: H04Q3/00
Filed: 1958-08-14
Abstract: 847,974. Automatic - exchange systems. TELEFONAKTIEBOLAGET L.M. ERICSSON. Aug. 14, 1958 [Aug. 14, 1957; June 19, 1958], No. 26158/58. Class 40 (4). In a marker-controlled system failure at the first attempt to establish a connection to a trunk in the wanted direction results in a test to see if a wanted trunk is available and if so, the existing non-numerical connection between the calling line and the marker is released and a new one set up. A first embodiment is described with reference to Figs. 1 and 2. A link relay set SR1 has access through switch GVA1 to only ten GVB bridges. It is therefore possible that all the bridges which can be used by SR1 for reaching trunks extending in the desired direction may be busy. It is still possible that other trunks extending in the desired direction may be idle but accessible only over other link relay sets in the group SR2-SR10. So, if a first attempt at connection by marker GVM fails a relay GG6 (Fig. 4, not shown) operates and connects up test circuits to the c-wires of all trunks accessible over the contacts of a relay W1 (not shown) corresponding to the desired one of ten routes. The test circuits also include the contacts of relays corresponding to the group selectors GVB so that if a test relay energizes it indicates the route which can be used. The register then releases cut-off relay BR in the subscriber's line circuit and operates line relay LR again so that the original connection set up by marker SLM over SR1 is released and a new non-numerical connection over a link relay set, say SR2, having access to the route indicated by the register, is set up. Two further embodiments are described, the one, Figs. 6-9, describing a system distinguishing between local and distant calls, the other, Figs. 10-12, a system in which two satellites are controlled by a register in the central exchange.

Title: Improvements in the manufacture and production of derivatives of coronene
IPC: C09B3/00
Filed: 1938-09-08
Abstract: 518,332. Coronene derivatives; dyes. JOHNSON, G. W. (I.G. Farbenindustrie Akt.- Ges.). Sept. 8, 1938, No. 26253. [Class2(iiiy]' Coronene derivatives can be obtained by condensing coronene with phthalic anhydride to form o-carboxybenzoyl-coronene and, if desired, further condensing the latter by heating or by treatment with agents splitting off water. The first condensation is effected by the Friedel- Crafts' reaction while using condensing agents such as aluminium chloride or ferric chloride. The coronene is preferably dissolved or suspended in an indifferent solvent, for example carbon disulphide, tetrachlorethane, monochlorbenzene or o-dichlorbenzene and the condensing agent and phthalic anhydride are added. By using suitable amounts of phthalic anhydride and condensing agent it is possible to condense one or more molecules of phthalic anhydride with one molecule of coronene. The resulting ortho-carboxybenzoyl-coronenes may be converted by ring-closure into vat dyes by heating them above the melting-points or by treatment with agents splitting off water, e.g. with aluminium chloride in the presence of a flux such as common salt, or with concentrated sulphuric acid, or its derivatives or with concentrated phosphoric acid. Methyl-sulphuric acid is especially suitable since sulphonation is avoided by its use. The products dye cotton orange-red to red shades. In the examples, coronene is. treated with varying amounts of phthalic anhydride to give ortho-carboxybenzoyl-coronenes, and the products are condensed to form vat dyes.

Filed: 1950-11-06
Abstract: 760,471. Helicopter rotors. LLOYD, P. D. Nov. 5, 1951 [Nov. 6, 1950], No. 27058/50. Class 4. A helicopter rotor having means for adjust ing blade pitch in res ponse to torque applied to the rotor comprises a shaft 23 having a head 26 capable of relative rotation, and a sleeve 27 surrounding the shaft and drivingly secured thereto at its lower end by a universal joint 34. The upper end o: the sleeve carries pivot ally mounted radia forks 30 which are con nected by extensible links 28 to collars 31 on the blade shafts 22. When the sleeve 27 is driving the head 26, lag-lead movements cause increase of pitch of the blades. Since the aerodynamic centre of each blade is located aft of the pitch axis aerodynamic force will tend to decrease the pitch of the blade in opposition to the increase in pitch due to torque until a position of equilibrium is reached. Rocking motion of the sleeve about joint 34 causes a cyclic variation of pitch and such motion may be automatic or impressed by manually operated controls. According to further embodiment in the Provisional Specification each blade, having its aerodynamic centre aft of the pitch axis, is mounted on its shaft by helical spines so arranged that centrifugal force on the blade causes it to increase pitch.
