Title: Controls for internal combustion engines
IPC: F02D11/04
Filed: 1973-01-23
Abstract: 1452923 Throttle controls G J WILKES 7 Jan 1974 [23 Jan 1973] 3357/73 Heading F1B I.C. engine throttle control provides a resistance to movement of the throttle control which varies in accordance with the inlet manifold vacuum. A casing 13 is divided by a diaphragm 16 into a compartment 14 which is connected to the inlet manifold and a compartment 15 which is open to  atmosphere. A rod 18 connects the diaphragm to a lever 24, pivotally mounted at 22 and connected by a chain 30 and tension spring 31 to a bell-crank 33 which is also connected to a rod 12 which reciprocates as the operators throttle control is moved. The rod 12 moves upwards as the operators control is moved in the throttle opening direction, turning the bell-crank until the chain is taut and spring 35 is extended to a degree at which the force applied to lever 20, 24 is just insufficient to move it against the combined effect of the economizer spring 25 or 28 and the inlet manifold pressure acting on the diaphragm 16. Further opening movement of the throttle requires either a substantial increase in the pressure applied by the operator or an increase in engine speed sufficient to reduce manifold pressure so as to move the diaphragm. In a first modification the economizer spring comprises a leaf-spring which engages the lever. In a second modification two links in series are inserted in the rod 12 and the shaft 18 is connected to the common articulation point of the links. In a third modification the shaft 18 is pivotally connected to one end of a lever which is pivotally mounted intermediate its ends and the other end of the lever engages the lever 12 between cheeks which allow lost-motion, the connection allowing movement of diaphragm 16 to be transmitted to rod 12 in either direction of movement.

Title: Improvements relating to monofuel reaction chamber apparatus
Inventor: TABBERER GEORGE
IPC: F02K9/68
Filed: 1955-02-04
Abstract: 816,752. Gas turbine plant. BRITISH THOMSON-HOUSTON CO. Ltd. Feb. 6, 1956 [Feb. 4, 1955], No. 3420/55. Class 110 (3). [Also in Group XII] In apparatus for producing a flow of gaseous working fluid by the decomposition of a monofuel within a reaction chamber, decomposition of the mono fuel is initiated by supplying to the reaction chamber a mixture of monofuel and a free oxygen-containing gas (such as air) in such proportions as to provide an ignitable composition. The starting mixture is ignited by means of an electric spark, and the flow of gaseous working fluid is subsequently maintained by the self-sustaining decomposition of monofuel, the supply of which is continued, while the supply of air is terminated and the spark device disconnected by an automatic control actuated by operation of a pressure switch responsive to pressure within the reaction chamber. In Fig. 1, upon operation of the control unit 22, the motor 16 drives pump 15, causing monofuel to flow from the tank 6 through a non-return valve 17 to the fuel and air inlet nozzle 3 into the reaction chamber 1. At the same time the solenoid 24 opens the on-off vave 20 whereby air under pressure flows from the storage bottle 19 through non-return valve 21 to the fuel and air inlet nozzle 3 and into the reaction chamber 1. After a certain interval the sparking-plug 5 is caused to discharge whereby the mixture in the chamber is fired. The pressure developed in the chamber 1 communicates through pipe 8 with a pressure intensifier 7 which is supplied with monofuel from the tank 6 through pipe 13 containing a non-return valve 14, the fuel discharging through pipe 9 containing a valve 10 and non-return valve 11 to the fuel and air inlet nozzle 3. When the pressure within the reaction chamber 1 reaches a certain value, the pressure switch 26 cuts off the supply to the sparking-plug 5, closes the valve 20 and stops the pump 15 and self-sustaining decomposition of the monofuel continues. The gases discharge through the outlet 2, for example to a starter turbine, and operation of the apparatus is stopped either by means of a time-switch or by a centrifugal switch on the starter. In a second embodiment, air from the bottle 19 enters the reaction chamber through an air inlet and the pressure of the air within the reaction chamber is caused to act on the pressure intensifier which causes monofuel to enter the chamber through a separate inlet nozzle disposed opposite the air inlet. In a third embodiment air from the storage bottle is divided, some passing through a pressure-reducing valve into the reaction chamber, and some passing at full pressure to a pressure-operated device whereby monofuel is caused to flow into the reaction chamber, the mixture of air and mono fuel formed in the chamber being ignited by means of an electric spark. Specifications 714,144 and 784,121 are referred to.

Title: Improvements relating to electric transformers
IPC: H01F27/42
Filed: 1927-02-08
Abstract: 286,431. British Thomson-Houston Co)., Ltd., Wellings, J. G., and Mayo, C. G. Feb. 8, 1927. Transformers for use with measuring instruments, tripping devices, relays, &c. are corrected or compensated to any desired extent in respect of phase-angle error, ratio error, or both, by means of auxiliary transformers supplying auxiliary excitation to the main transformers in approximately lagging quadrature. For this purpose the magnetizing current in the auxiliary transformer is made large compared with its output current, preferably by running at a high flux density, by using a core of high reluctance or both. In the arrangement for phase-angle correction shown in Fig. 1, the main tranformer 20 and auxiliary transformer 20<1> have a common bar primary 21 and cores of the same diameter but different cross-section, the auxiliary core being about <1>/4 to <1>/10 of the size of the main core, while a single coil 23<1> on the auxiliary coil is connected through an adjustable impedance 25 to an additional coil 24 of two turns on the main core, the secondary coil of nineteen turns being connected directly to the burden. The arrangement for correcting both phase-angle and ratioerrors shown in Fig. 6 includes also an additional secondary coil 26 of one or more turns connected in series with the secondary coil 23 of the main core; in modifications of this arrangement, the coil 23<1> is connected only to the impedance 25 or is dispensed with. In the arrangement shown in Fig. 14, the main core is divided into two parts 20<a>, 20b, and the divided additional windings 24 are cross-connected to the coil 23<1>; in modifications of this arrangement the auxiliary core may be half the size of the main core, the divisions of the main core may be of unequal size, and the winding 26 may be dispensed with. Specifications 169,093 and 259,198 are referred to. According to the first of the Provisional Specifications, the main and auxiliary transformers are of different current ratio and the cores are of different sizes but the same material, while the ratio of the turns of the secondaries is equal to that of the mean lengths of the magnetic circuits, so that the cores work at equal flux density. The cores may thus be of different diameters, so that one may surround the other. The core of the auxiliary transformer may be a tube or punchings of sheet steel; or of sheet steel in zig-zag formation.

Abstract: 918,078. Spectrophotometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 2, 1961 [Feb. 3, 1960], No. 3891/60. Class 97 (1). [Also in Group XL (b)] In a spectropolarimeter a pair of prisms of birefringent material both form the monochromator and act as polarizer and analyser. Light from a xenon arc 11 passes via mirrors 12, 14, 15 and the entrance slit 13 to a prism 16. It then passes through a modulator 18, specimen 19 and a compensator 22 to a prism 24 and a photo-multiplier 29. The ray path through the instrument includes the ordinary ray through one prism and the extraordinary ray of the same wavelength through the other. The wavelength is selected by rotating mirrors 15, 25 about a common axis. The modulator 18 comprises either a stepped quartz plate, which oscillates the plane of polarization as it rotates together with a uniform quartz plate of the opposite activity or a Faraday cell. The output of detector 29 is fed to a phase sensitive rectifier and any out-of-balance current is fed back to a Faraday cell compensator 22 which may be the modulator, to counterbalance the rotation due to the specimen. The magnitude of the feedback signal is recorded automatically as mirrors 15, 25 track through the specimen. Mirror 23 may be modified, Figs. 2 and 3 (not shown), to render the beam therefrom to the prism 24 parallel to that from prism 16 to mirror 17. Means are described to mount the mirrors 15, 25 for simultaneous rotation. Specification 882,244 is referred to.
