Patent GB-358901-A (GB)
Abstract: 358,901. Anti-aircraft gun sights. PRECISION MODERNE, 61, Rue Pernety, Paris. July 7, 1930, No. 20502. Convention date, July 9, 1929. [Class 92 (ii).] In means for automatically applying the lead angle between the gun and the sight when firing at moving aerial targets, the space figure OBAA<o>, Fig. 1, representing the gun axis OB, the gravitydrop BA, the target traverse AA‹, or V(t + e), and the sight line OA<0>, is reproduced in the sighting apparatus to a scale 1/t + e by the similar figure obaa<0> where t is the time of flight increased by a time e to ensure a burst in front of the target and V is the speed of the target. In the apparatus, the gears for simultaneously varying the distances ob, ba ensure the relation OB = K(t + e) - K<1>AB where K and K<1> are constants. In the apparatus shown in Fig. 2, a rod 33 carrying the sight 40 telescopes at one end in a universal joint 34 carried by a slide 36 moved by a screw 37 kept parallel to the gun 5 by links 7, 9. The other end of the rod 33 is universally jointed to a rod 19 carried by a cylinder 13 adjustably mounted for rotation and vertical movement in a box 12 kept horizontal during elevational movements of the gun by its attachment with the arm 9. Rotation of the cylinder 13 during training is compensated by a gear 27, 24, 23 having a clutch 26 which permits of setting the cylinder by means of an arrow 16 in the direction of target flight. Spring plungers 31 prevent accidental rotation of the cylinder during firing. The adjustment of the slide 36 to a range scale 47 by rotation of the screw 37 is effected by a hand gear operating a pinion 44 which rotates a threaded sleeve 45 engaging a non-rotarv screwed sleeve 14 which causes the vertical adjustment of the cylinder to vary the distance ba in relation to the range. Radial adjustment of a slide 10 carrying the rod 19 is effected by a pinion 15 operated by the vertical movement of a sleeve 22 that engages the sleeve 14 when rotated by setting a lever 35 to a speed scale 53. Instead of using the range scale 47, a pointer 48 may be set to height curves on a disc 49 rotated in accordance with gun elevation by a pinion 51 thereon which moves over a fixed sector 50. Variation in range is shown by a pointer 52 moving over a scale 46 on the rod 33. To correct for speed and direction of wind, the box 12 may be mounted for radial and rotational displacement in an outer frame connected to the link 9.

Title: Fuel COntrol Systems for Gas Turbine Engines.
Inventor: LAWRENCE OWEN NAPIER
Filed: 1966-02-15
Abstract: 1,179,230. Gas turbine jet engine combustion equipment. JOSEPH LUCAS (INDUSTRIES) Ltd. Feb.14, 1967 [Feb.15, 1966], No.36149/69. Divided out of 1,177, 634. Heading F1J. A gas turbine engine fuel system comprises a first passage connected to the outlet of a pump, further passages connected between the first passage and primary and main burners respectively, a flow control device in the primary burner passage to control the fuel flow to the primary burners in accordance with changes in a predetermined variable, a servo-operated throttle valve in the first passage to control the supply of fuel to the primary and main burners, the throttle valve being controlled from the device for controlling the fuel flow to the primary burners, variable operator-controlled valves in the further passages respectively, for controlling the fuel supply to the primary and main burners, and a device in the main burner passage for regulating the fuel flow to the main burners as a function of the flow to the primary burners. The invention is described with reference to a fan-type engine in which fuel is burnt in the fan duct to provide additional thrust, particularly an engine of this type in which the direction of thrust and the effective area of the exhaust outlet can be varied, additional thrust being required when the exhaust outlet is directed to provide a component of lift. The invention is also applicable to by-pass type engines. A fuel pump 18 is driven by an air turbine 17, the air being conveniently obtained from the engine compressors. Air inlet valve 15 and fuel inlet valve 19 are opened by a manual control 13. Another manual control 14 controls an air inlet valve 16 and actuates a drive mechanism (not shown) for inclining the exhaust outlet; in addition, it controls a multiple valve 20 having three lands for controlling the supply of fuel through pipes 10, 11 and 12 to the primary, main and igniter burners respectively of the fan duct. The flow through the pipe 10 to the primary burners is controlled by a device 52 comprising a throttle valve formed by an extension of a piston 54 which is controlled by a half-ball valve 59 actuated by a capsule 72 subjected to, say, the pressure rise across the fan. A further half-ball valve 67 actuated by a piston 64 subjected on opposite sides to the pressures upstream and downstream of the throttle valve formed by the extension of piston 54 controls a throttle valve 21 on the discharge side of the pump 18 to maintain the difference between these pressures at a constant value. The main burners are supplied through a pressurizing valve 74 which is arranged to provide a pressure drop equal to that maintained across the throttle valve formed by the extension of piston 54. Consequently the pressure at the main burners which is dependent on the opening of the valve 20 is a function of that at the primary burners, and the flow-rates are in the same relationship.
