Title: A steam boiler and turbine installation
IPC: F01K7/24
Filed: 1965-03-15
Abstract: 1,063,236. Controlling superheat. SIEMENSSCHUCKERTWERKE A.G. March 15, 1965 [March 14, 1964], No. 10949/65. Heading F4A. [Also in Divisions F1 and G3] In an installation having a forced-flow oncethrough boiler, a fall in the temperature of live steam upstream of a high-pressure turbine stage 7 is corrected by reducing, by a motordriven valve 12, the amount of water injected at 11 between two parts 4, 5 of a superheater 3, 4, 5 in the boiler. When water injection is reduced to zero any further fall in steam temperature is corrected by opening a motor-driven valve 25 to permit some steam to flow through line 24 and rejoin the main flow at an interstage reheater 8 in the boiler, upstream of a lowpressure turbine stage 9 and condenser 10. The valves 12, 25 are regulated by controllers 20, 13, 26 (see Division G3) in accordance with deviations of the temperatures sensed at 15, 16, 17 from desired valves pre-set at 21, 22. Feed water is regulated by controllers 19, 18, the controller 18 comparing the temperature sensed at 14 with the desired value pre-set at 23.

Title: Method and apparatus for fusing refractory materials
IPC: C04B33/32
Filed: 1945-05-01
Abstract: 608,950. Automatic control for furnaces. NORTON CO. May 1, 1945, No. 11021. Convention date, May 8, 1944. [Class 38 (iv)] [Also in Group XII] Current.-In an electric furnace (see Group XII), the three electrodes are individually raised or lowered automatically relatively to the mass of fused material on the furnace heath, accordingly as the current flowing to the electrode rises or falls. As shown, the electrodes 13-15 are carried on vertically adjustable posts 19-21, the adjustment being effected by units 125a-c, each comprising a winch driven by a reversible motor. The power supply 115-117 is connected through step-down transformers H1-3, L1-3 to conductors 122-124 and the electrodes. Each conductor 122-124 is provided with a suitable low resistance or preferably with a transformer 130a-c having its primary winding in the conductor and its secondary winding connected to a coil 126a-c. Current changes in the conductors thus actuate spring-biassed armatures 132a-c either to close contacts 134a-c or contacts 135a-c, causing rotation of the motors in the units 125a-c either in one direction or the other. The rates of current flow are determined by the setting of the manual controls 120a-c and the electrodes may be raised or lowered by the manipulation of the levers 129a-c.

Title: Improvements in and relating to helicopters
IPC: B64C1/00
Filed: 1948-04-22
Abstract: 646,866. Multi-rotor helicopters. CIERVA AUTOGIRO CO., Ltd., PULLIN, C. G., and SHAPIRO, J. S. April 22, 1948, No. 11088. [Class 4] In a helicopter having two or more horizontally spaced lifting rotors whose torque reactions are not balanced and thus produce a residual torque, and wherein control systems are provided for varying the collective pitch of all the rotors equally in the same sense, and for controlling the helicopter in yaw respectively, each system having a separate pilot's control member, the systems are so interconnected that operation of the collective pitch control member, with the yaw control member held steady, operates the yaw control system to compensate for the change in residual torque due to change of collective pitch of the rotors, while operation of the yaw control member, with the collective pitch control member locked, does not affect the collective pitch control system. Fig. 4 shows the control system for a helicopter with three lifting rotors as described in Specification 591,982 (the pitch control systems being as described in Specifications 646,865 and 646,867), in which a spider with three arms 47, 48, 49 is connected by links 50, 51, 52 to the collective pitch control mechanisms of the three rotors, and is moved vertically by actuation of a pitch control lever 40, acting through links 68, 69, 70, 73, 74. Yaw control is effected by rudder pedals 39 actuating levers 86, 87, 82, the latter being connected to a pivoted T-bar 75, the ends of whose arms are connected by vertical links 77, 78, 79 to the cyclic pitch control mechanisms of the lifting rotors. The links 86, 87 are connected by a balance lever 88 carried by a pivoted idle lever 89 and attached at one end to a link 91 carried by the lower end of the lever 68 mounted on the shaft carrying the collective pitch control lever 40. When the latter is held fixed, the link 91 acts as a fixed anchorage and movement of the rudder pedals 39 actuates the T-bar 75 only, and has no effect on the collective pitch control system. When the rudder pedals are held stationary, operation of the pitch control lever 40 results also in rotation of the balance lever 88, and movement of the links 87, 82 and the T-bar 75, to effect appropriate operation of the yaw control system. The mean residual torque may be compensated by permanent, built-in, inclination of the rotor axes, and the arrangement is preferably such that the torque-compensating couple becomes zero when the rotor pitch is reduced to that for autorotation. Preferably all the rotors are driven in the same direction. The collective pitch control spider may be replaced by a T-bar which, like the T-bar 75, may be constructed and power-operated as described in Specification 646,864. Specifications 615,156, 616,227 and 644,524 also are referred to.

Filed: 1973-03-08
Abstract: 1421433 Anti-lock braking systems AUTOMOBILES CITROEN 8 March 1973 [9 March 1972] 11350/73 Heading F2F An anti-lock vehicle braking system has a valve 2 operable by a device responsive to the dynamic rotational state of wheel to disconnect a conduit 3 leading to a source of fluid under pressure from a conduit 4 leading to a brake cylin - der 1 and connect conduit 4 to an exhaust conduit 5; fluid is thereby exhausted from the cylinder 1 to a reservoir 6 but the exhausting takes place in two stages by two different routes. Initially the fluid exhausts via an auxiliary conduit 35 having associated therewith an auxiliary flowlimiter 38, but whilst this is occurring the chamber 41 of an accumulator 8 also fills with exhausting fluid until such time as a moving member 39 of the accumulator 8 is caused to move against the action of a spring 40 and operate a valve to close off conduit 35; thereafter flow to reservoir 6 takes place via a flow-limiter 50 the flow via this path being slower than via the first path, the flow limiter 38 having a pressure drop less than that of flow-limiter 50. In the embodiment of Fig. 1 the valve operable to close off conduit 35 comprises a slide 36a connected to the moving member 39 (e.g. piston or elastic membrane) of the accumulator 8. The accumulator has a second chamber 42 connected to conduit 35 by a conduit 43. The flow-limiter 38 may be connected in conduit 35 (as shown) or in conduit 5. In the embodiment of Fig. 2 the auxiliary flow-limiter is constituted by an aperture 46 in the piston 39 of the accumulator 8 which piston is movable to close a valve constituted by an edge 44 and the adjacent bearing surface 45 of piston 39 to close off conduit 35. A portion 5b of the exhaust conduit 5 connected to chamber 42 contains the flow-limiter 50. In the embodiment of Fig. 3, the chamber 42 is of constant volume and the conduit 35 opens into chamber 42 whilst portion 5b of conduit 5 opens into chamber 41. The aperture 46 is in parallel with flow-limiter 50. Fig. 4 (not shown) illustrates a practical form of the arrangement of Fig. 3 wherein flowlimiter 50 is an aperture in a plug (51) closing chamber 41. In the embodiment of Fig. 5 (not shown) a portion (35a) of conduit 35 containing auxiliary flow-limiter 38 is connected between portion (5a) of conduit 5 leading from valve 2 and a fixed volume chamber 42. In the embodiment of Fig. 6 the flow-limiter 50 is constructed to have a variable pressure drop. It comprises a body 26 and a slide 27 with a passage 33 therebetween connected to a groove 34. The slide 27 is in equilibrium under the opposing actions of a spring 28 and of the pressure supplied by a conduit 29 connected to conduit 4. The variable flow-limiter 50 of Fig. 6 may be used with any of the other embodiments.

Title: Improvements in vinyl resin compositions
IPC: C08K5/20
Filed: 1947-04-30
Abstract: The composition comprises a vinyl chloride polymer or copolymer and a diester-amide R CON(C2H3R1OOCR)2 (for preparation thereof see Group IV (b)), where R is an alkyl radicle of 2-8 carbon atoms and R1 is H or CH3. Esteramides instanced are 2,21-(2-ethylhexanamido)-diethyl di-(2-ethylhexanoate) which is preferred and 2,21-butyramido-diethyl dibutyrate, 2,21-(2 - ethylbutyramido) - diethyl di - (2 - ethylbutyrate), 2,21-nonamidodiethyl dinonanoate and p 2,21-(2-ethylhexanamido)-di-isopropyl di-(2-ethylhexanoate). Diester-amides derived from the lower fatty acids such as propionic and butyric acid are stated to be more compatible with cellulose acetates than the preferred amide.  Copolymers instanced are those comprising vinyl chloride with vinyl acetate and alcohol and acrylonitrile and may be solids or liquid dispersions or pastes derived from emulsion polymerized vinyl chloride optionally with hydrocarbon or ketone solvents.  The diesteramide is present in amounts of from 10 to 50 per cent by weight of the solid composition and up to 60 per cent by weight in a liquid composition.  The ester-amides act as stabilizers as well as plasticizers and may be used in conjunction with iron pigments.ALSO:Diester-amides RCON(C2H3R1OOCR)2, where R is an alkyl radicle of 2-8 carbon atoms and R1 is H or CH3, are prepared by heating under reflux, e.g. at about 125 to 200 DEG  C., a mixture of 1 mol. of di-ethanolamine, di-isopropanolamine, or N-hydroxy-ethyl N-hydroxy isopropanolamine with at least 3 mols. of the appropriate acid, anhydride or acid chloride.  The reaction is preferably effected at reduced pressure or in the presence of a water-immiscible liquid such as benzene, toluene, xylene or dibutyl ether in which case water is removed by azeotropic distillation.  Thus 2,21-(2-ethylhexanamido)-diethyl di-(2-ethylhexanoate) is obtained by heating one mol. of diethanolamine with four mols. of 2-ethylhexanoic acid in xylene solution at not above 170 DEG  C., water formed being constantly removed, or by heating the above reactants at 150 DEG  C. and 30 mm. Hg in both cases; heating is continued until the required amount of water is removed- 2,21-Butyramidodiethyl dibutyrate is obtained by mixing equimolar quantities of diethanolamine and butyric anhydride at 50 DEG  C., adding 3.25 mols. of butyric anhydride at 125 DEG  C. and heating at 140 DEG  C. for 4 hours, the products being obtained by a vacuum distillation of the reaction mixture. 2,21-(2-Ethylbutyramido)-diethyl di-(2-ethylbutyrate) is prepared by azeotropic distillation of 1.3 mols of diethanolamine and 4.1 mols. of 2-ethylbutyric acid from xylene at 172 DEG  C., similarly 2,21-nonamidodiethyl dinonanoate from 3.14 mols. of nonanoic acid and 1 mol. of diethanolamine at 150 DEG  to 173 DEG  C. and 2,21-(2-ethylhexanamido) di-isopropyl di-(2-ethylhexanoate) from 1 mol. of di-isopropanolamine and 4 mols. of 2-ethylhexanoic acid.  The products are used as plasticizers for vinyl chloride polymers and copolymers (see Group IV (a)).
