Abstract: 896,444. Direct lift aircraft. HAWKER AIRCRAFT Ltd. Jan. 12, 1961 [Jan. 22, 1960], No. 2526/60. Class 4. A fixed wing aircraft which can take-off and land vertically, or at a speed below stalling speed, lift being obtained by substantially downwardly directed jets, has longitudinally arranged strakes on the undersurface of the fuselage or other nozzle carrying part to intercept the gases deflected upwardly off the ground and prevent their upward flow over the sides of the fuselage or part by deflecting the gases downwardly. In the aircraft shown partially in side elevation in Fig. 1 and front elevation in Fig. 3, gases are discharged downwardly from nozzles 2, 3, on either side of the fuselage to provide direct lift. The nozzles are adjustable to provide forward thrust also. In such an aircraft, circulation of the discharged gases beneath the fuselage and upwardly over its sides, reduces the lifting effect when the aircraft is close to the ground. Fore and aft extending strakes 5 intercept this circulation, and direct the gases outwardly and downwardly away from the fuselage to reduce the lift loss. The strakes may be adjustable and retractable and may also act as bomb bay or undercarriage bay doors. A lateral fence 7 retractable by jack 10, extends between the forward ends of the strakes, and an undercarriage bay door 6, retractable by jack 11, extends between the rearward ends, and may also be usable as an airbrake. Recirculation of hot gases into the engine intakes (not shown) is also prevented by this means. Specification 861,480 is referred to.

Title: Improvements in Feed Pump Pressure Regulators.
IPC: F22D5/18
Filed: 1916-02-28
Abstract: 104,372. British Thomson - Houston Co., and Halliwell, R. F. Feb. 28, 1916. Governing pumps.-A pressure regulator for boiler feedpumps comprises a piston 13 connected by a rod 14 to the valve-gear 12 of the valve of the turbine &c. driving the pump, and movable easily in a cylinder 8. The space above the piston is connected by a pipe 9 to the delivery side of the pump, and a channel 15 in the piston and piston rod communicates with a wastepipe 11, which may lead to the suction side of the pump. Owing to the loose fit of the piston some pressure water leaks into the space below the piston, and escapes by the channel 15 when the valve 16 is open. This valve is exposed on its lower face to the pressure in the steam-pipe and is normally open. When the pump pressure rises, the piston 13 is forced down, so that the valve is closed and the pressure in the space below the piston increases until the piston 16 is forced downwards against the steam pressure. The downward movement of the piston 13 tends to close the steam valve of the prime-mover and so reduces the speed of the pump and the delivery pressure. Owing to the differential form of the piston 13, the pump pressure exceeds the steam pressure.
