Title: Improvements in or relating to pitch changing mechanisms for propellers
IPC: B63H3/08
Filed: 1951-10-30
Abstract: 700,394. Variable-pitch propellers. UNITED AIRCRAFT CORPORATION. Oct. 30, 1951 [Nov. 1, 1950], No. 25338/51. Class 114 A variable-pitch propeller having a fluidoperated pitch changing motor operative to move the blades in a normal range and a reverse-pitch range, comprises co-operating elements 33, 150 operative where the blades reach a predetermined reverse pitch position for limiting the pressure acting on the motor piston 32 to that which is only sufficient to overcome the force exerted in the opposite direction due to the centrifugal blade twisting movement which tends to move the blades towards the low-pitch position during rotation. The movement of the motor piston 32 in the low pitch position of the normal governor-controlled constant-speed range is limited by stops 68 which are engaged by a sleeve 35 secured to the piston. The stops are held outwardly by a wedge 90 loaded by a spring 92 and secured to a sleeve 96, loaded by a second spring 110, which carries a piston 104 operable in an axially adjustable cylinder 72. For reversing the blades high pressure liquid supplied by a pump 122 through passages 44, 48 to the inboard side of the piston 32 acts through an annular passage 120 and opens a spring loaded sleeve valve 130 whereby the pressure liquid acts on the inboard side of the piston 104 and moves the latter and the wedge 90 outwardly thereby releasing the stops 68. At the extreme reverse pitch position, bleed ports 150 in the sleeve 35 move past a packing ring 33, carried by an axially adjustable sleeve 38 and place the opposite sides of the piston 32 in communication with one another thereby limiting the movement thereof. A mechanical reverse-pitch stop may also be fitted. Specifications 505,077. 514,725,607,856 and 636,402 are referred to.

Filed: 1959-07-29
Abstract: 898,963. Fluid-pressure servomotor-control systems. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 13, 1960 [July 29, 1959], No. 25990/59. Class 135. The liquid level in a tank is controlled by apparatus comprising a dip pipe opening below the surface of the liquid in the tank, a liquid supply control valve, means to supply air through parallel branches to the dip pipe and the liquid supply control valve, and a control unit 17 actuated by pressure changes in the dip pipe to adjust a pilot valve 3 for regulating the liquid supply control valve. An air inlet 1 supplies the pilot valve 3, through a restrictor and a junction 9 leading to the liquid supply control valve, and the dip pipe through a restrictor 11 and a bubble chamber 12. A pair of diaphragms 4, 14 of different diameters are mounted in the control unit 17 to actuate the pilot valve 3 and have the spaces 5, 6 below and above them connected respectively to the outlet of the valve 3 and by a pipe 19 to the dip pipe supply. To enable the controlled level to be varied the space 15 between the diaphragms is connected by a pipe 16 to an air supply, the pressure of which can be adjusted. To permit direct reading of liquid level on a pressure gauge graduated in pounds per square inch, the ratio of the diaphram areas may be chosen so that the pressure in pounds per square inch in the space 15 is equal in numerical value to the dip pipe back pressure in feet water gauge. The sensitivity of the control unit may also be varied through an adjustable restrictor 8 venting to atmosphere. In an alternative arrangement in which only one diaphragm is provided and the pipe 16 omitted, the dip pipe may be adjusted to vary the controlled level. A falling liquid level is arranged to increase the pressure of the supply to the control valve.
