Title: Gas turbine engines
Inventor: BARNARD MARK CARY SEDGWICK
IPC: F01D17/26
Filed: 1970-02-18
Abstract: 1285544 Gas turbine engines - control DEFENCE SECRETARY OF STATE FOR and LEYLAND GAS TURBINES Ltd 19 April 1971 [18 Feb 1970] 7680/70 Heading F1G The invention relates to a gas turbine engine of the type having a separate power turbine, the power turbine having variable area inlet nozzles, the power-operated inlet nozzle actuating mechanism being controlled such that the rate of movement thereof is so correlated with the operation of feedback control means actuated by an error signal derived from the difference between the engine operating temperature and a preset datum that the time needed for completion of a movement of the nozzles sufficient to produce a significant increase in the operating temperature exceeds the time during which the feedback control means is in operation. In the embodiment shown the motor 2 controls the position of stop 7 through reduction gear 8, the motor being controlled by a signal from a thermocouple sensing engine operating temperature, a temperature above normal acting to increase the inlet area of the inlet nozzles tending to reduce the temperature. The mechanism comprises a cylinder 1 with a primary piston 4 and a control piston 5, the piston 4 being connected, through piston-rod 6 and linkage 6A to the adjustable inlet guide vanes. In the steady state condition the two pistons are held in contact with the stop 7 by air-pressure supplied through line 10 to the cylinder space 18. Air under pressure is also supplied through line 11 to the cylinder space 17 at the face 14 of the control piston 5, supply being controlled by valve 12, the valve being energized to the closed position when the speed of the gas generator shaft is the same as that demanded by the control lever. Air under pressure is also supplied through line 19 to the cylinder space 21 between the primary and control pistons, the supply being controlled by valve 20 such that air is supplied to the space 21 when the valve is open whereby the primary piston 4 is moved away from the control piston 5, this movement of the piston causing the inlet nozzles to move to the reverse position. During deceleration the control piston 5 moves away from the stop 7 by a differential speed signal which de-energizes the solenoid valve whereby the valve is opened. During acceleration the control piston 5 is moved away from the stop 7 by a differential speed signal which de-energizes the 'power' solenoid valve; the primary piston 4 may also be moved away from the control piston 5 if the 'reverse' solenoid valve 20 is energized.

Abstract: 416,494. Race games. SCRUBY, B., Stafford House, Harlow, Essex, and HARKNESS, G. K., 55, Gresham Road, Brixton, London. March 15, 1933, Nos. 7808, 12943, 17211, and 22666. [Class 132 (ii).] In apparatus for playing a race game, a number of figures representing competitors are moved in a step-by-step manner in given paths by projectiles, each of which is rolled along a board of the bagatelle type so as to move one of the figures by luck or skill. A number of figures 1 are each supported by a stem 2 on a bar slidable in a channel 4. The stems 2 move in slots in a board 6 representing a race course. The figures are moved by impulses received from balls 8 which fall through holes 11<a>, 11<b> on to inclined channels 9 from which they run on the guide channels 4 for the figures. After impact, the balls fall sideways on to an inclined board 24 and roll down towards one end when they drop through a space 26 on to shoots 28 by which they are directed through the central opening 27 on to one or other of the transverse inclines 19. The end ball on each side may run on to the end of a lever 20 in a narrow compartment formed between the walls of the apparatus and partitions 16. When the projecting end of the lever 20 is raised, the ball 8 runs on to board 10 and thence through one of the holes 11<a>, 11<b>. The figures 1 are all returned to the starting position by a transverse bar slidable on longitudinal bars and connected to a member which prevents the balls from falling from the board 24 through the opening 26 on to the inclines 19 until the figures are returned. Coin-freed apparatus 48 may be provided to control the movement of the end ball 8 on to the lever 20. The board 10, vertical partitions 16 and liners 10 are secured to the outer casing with glass top 15. The remaining parts form a separate unit which may be withdrawn as a whole together with the end wall 25. In a modification, the figures are connected by endless wires to toothed ratchetlike wheels on to which the balls fall from holes arranged in a single row in the board 10. As the wheels are thus rotated, the balls fall on to a board with inclined walls which guide the balls towards the centre and into diagonal conduits from which they are led to the levers 20. In a further modification, Figs. 9 and 10, figures such as a hare 101 and hounds 100 move along grooves 103 in the board 104 and receive impulses from balls projected along the board and guided by the end wall 106, pins 115 and wires 108-114 on to the figures.

Title: Oil rectifying systems for internal combustion engines
IPC: F16N39/00
Filed: 1929-03-11
Abstract: 330,600. Marks, Sir G. C., (Automotive Device Co., Inc.). March 11, 1929. Recovering waste lubricants. - Used lubricating oil of an internal combustion engine is freed from volatiles bv the heat of the exhaust gases transmitted through a highly conductive plug extending into the exhaust and having a cross-sectional constriction whereby quick initial and subsequent restricted heating is attained. The used oil is fed from the lubricating system of the engine through a pipe 31 and an inlet valve 32 to a tank 27. When a valve 37 is opened the oil falls through a pipe 33 and an inclined passage 48 to a copper oil-vessel 22 screwed on to the upper reduced part 21 of a copper plug 18 having heat-collecting fins 19 extending into the exhaust manifold 13 and arranged edgewise to the travel of the gases. The vapours evolved into the vaporizing chamber 26 are drawn through pipes 66, 67 to the air-intake 69 of the carburetter. The purified oil overflows into the chamber 26, and if sufficiently cool passes by a valve 64 controlled by a thermostat 65 to a pipe 61 and the crank-case 62; if hot enough to keep the valve 64 closed the oil fills the chamber 26 until it flows over a wall 57 to passages 58. 59, of the pipe 61. Air, gases and vapours are drawn from the crank-case through a pipe 72. the chamber 26, and the pipes 66, 67, incidentally reducing the vacuum in the chamber 26. The tops of the chambers 26, 27 are connected by a pipe 55 fitted with a valve 56 which closes under the pressure of the oil-pumping through pipe 31, but which is opened by its spring when the pumping ceases and so equalizes the pressure in the chambers. The valve 37 is normally closed by a spring 41 supported by an adjustable plug 35. It is opened when a thermostat T within the oil-vessel 22 is heated, and thereby expanded, sufficiently to depress the stem 36 against the pressure of the spring. The thermostat comprises reversely-curved elements 45, 46 each formed of a pair of strips of different nickel-steel alloys having substantially different coefficients of expansion. To reduce friction the ends 49 of each element are reversely curved, and the edges coact with knife-edges 53 in extensions 52 of the arms of a yoke 51 about the valve 37. Canting on the valve-stem 36 is limited by knife-edges 54 on the yoke arms. The plug 18 and chamber 22 are heat-insulated from the manifold and the chamber 26 by suitable washers.
