Title: Fuel system for gas turbine powerplants with torque limiting mechanism
IPC: F02C9/32
Filed: 1958-11-04
Abstract: 870,834. Fluid-pressure servomotor control systems. UNITED AIRCRAFT CORPORATION. Nov. 4, 1958 [Nov. 15, 1957], No. 35341/58. Class 135. [Also in Group XXVI] A gas turbine engine comprising compressor, combustion and turbine sections 10, 12 and 14, Fig. 1, respectively, has the latter arranged in two parts the first of which 22 drives the compressor 10 whilst the second part or free turbine 26 is connected to an aircraft propeller or helicopter rotor 30. Control of the engine is effected by a fuel throttle 50 consisting of a cylindrical closure 52 reciprocable within a sleeve 54 incorporating a port 66, which sleeve is slidable in a bore 56 that communicates with fuel inlet and outlet conduits 58, 60, the closure 52 embodying inlet and outlet ports 62, 64; fuel flow into the. outlet conduit 60 is determined by the relative positions of ports 64, 66. The closure 52 is urged to the minimum flow position by a spring 68 between a flange 70 and the sleeve 54 whilst a pressure regulator, not shown, ensures a constant pressure differential between conduits 58, 60. The closure 52 is actuated by a spring-, loaded single-acting piston 74 via a pair of rollers 84 contained between the flange 70 and an inclined bar 86, the position of the piston 74 being determined by the position of a hinged closure 92 relative to a discharge orifice 90 leading from the cylinder 88 of piston 74 and to which fluid is supplied under constant pressure. The angle of the bar 86 is dependent upon the compressor discharge pressure whilst the movement of a throttle lever 34, Fig. 1, and compressor speed and inlet temperature signals are coordinated to determine the position of the hinged closure 92, Fig. 2. To limit the torque in the propeller or rotor drive another hinged closure 104 is provided which co-operates with an orifice 106 that communicates with the cylinder 78, the closure 104 being moved clockwise in response to ram pressure signals supplied to a corrugated diaphragm 114, and anticlockwise by speed signals from the free turbine 26 acting through a plunger 120; the closure 104 may also be moved anticlockwise by a hand lever 130 via a plunger 124 and a cam 128. The closure 104 is connected to the throttle valve closure 52 by a spring 134, bell crank lever 136, plunger 134 and a link 132 to provide "follow-up."

Abstract: In the dry-cleaning of textiles with organic solvents containing an organic detergent, clogging of the filters and transmission of the soil to another part of the textile are avoided by the further addition to the solvent of a substance having a flocculating action on the soil, the detergent and the flocculant being added together in the form of an emulsion or dispersion with a solvent.  The flocculated soil may be removed by filters or centrifuges.  The solvents specified comprise benzine, trichlorethylene, perchlorethylene and carbon tetrachloride.  The organic detergents referred to comprise oleates and ammonium salts of alkyl aryl sulphonates and in particular sodium dodecyl benzene sulphonate, sodium monyl naphthalene sulphonate and sodium dioctyl naphthalene sulphonate; other detergents specified are diisohexcyl, heptyl phenol polyglycol ether, diisobutyl isopropyl phenol polyglycol ether, and diiso-monyl heptyl phenol poly-glycol ether.  The flocculating substances may comprise phosphates including polyphosphates, silicates, colloidal silica, kieselguhr, starch and its derivatives, cellulose derivatives, mucilages, vegetable greases, alginates, carbon, synthetic resin partial condensates such as dimethylol-urea, and metal hydroxides.  In the case of metal hydroxides which tend to flocculate prematurely an additional agent is preferably added therewith to stabilize them.  Suitable agents comprise alkaline earth salts of high molecular weight fatty acids, alkaline earth salts of acid sulphuric acid esters of fatty alcohols, alkaline earth salts of sulpho derivatives of aliphatic-aromatic hydrocarbons, and emulsifying agents such as diglycol oleate, heptylamine polyglycol ether, cetyl-methyl cyclohexylamine oxide and decyl guanidine.

Abstract: 338,013. Ludlow, J. H., and Associated Electrical Industries, Ltd. Nov. 25, 1929. Tilting furnaces. - A lip-tilting crucible furnace is tilted by chains connected to the furnace through mechanism constrained to move away from the tilting axis about a fixed point or points, and so arranged that the point of attachment of the chains has a smaller angular movement about the tilting axis than the furnace. By this means the pulley 11 round which the chains pass to the counterweight can be arranged below the level of the working-platform 21. In the construction shown in Fig. 1 the chains are connected to levers 5, and pass over pulleys 8 attached to the lower rear corners of the furnace. The levers are pivoted to the framework 4 at points 7 to the rear of the tilting axis 2, and each carries a bowed member 6, on which rides a roller 9 at a lower front corner. The tilting is effected by a motor 12 controlled by limit switches 16, 17. In the construction shown diagrammatically in Fig. 4 the chains pass over pulleys 8 at the lower rear corners of the furnace and are connected to the free points E of systems each comprising links 23, 25 pivoted to fixed points F, G, a lever 28 pivoted on the axis of the pulley 8 and connected to the free end of the link 25, and a link 29 pivoted at the point E and connected to the lever 28 at a point 30 between its ends.
