摘要： An actuator comprising a body having a bore, a piston in said bore and having a piston rod. A system pressure gallery or passage is arranged in the body for the application of system pressure to the annular area between the piston and the piston rod, and a chamber is provided in the body for applying pressure to the other end of the piston. The chamber communicates with the system pressure passage through a fixed orifice, and with an exhaust outlet through a variable orifice controlled by a flapper disc arranged to close the end of an outlet tube. The flapper disc has on its opposite face a pressure balancing tube of the same diameter as the outlet tube and working in a bore in the piston. The pressure in this bore is equalized to the exhaust pressure and the flapper disc is controlled by the spring centered armature of a solenoid or force motor.

摘要： A method of forming a fluid-tight seal between two surfaces including the steps of forming at the surfaces to be sealed an annular recess for the sealing elements, the recess having a cylindrical outer surface and being wedge-shaped in radial section, tapering inwards, and with a radius curve between the outer and the wedge surfaces, and fitting into the recess sealing elements comprising an O-ring surrounded by a collar of a plastics material which is flexible but does not flow under the conditions in which the seal is required to operate, the relative dimensions being such that the ring and collar are deformed on tightening the seal, and then tightening the surfaces together to compress the O-ring and to deform the collar against the surfaces of the sealing recess.

摘要： A device for controlling the pressure of fluid applied to or the flow of fluid to a hydraulic actuator comprises a pilot valve for controlling a pressure operated main valve. A transducer converts an electrical input signal into a force which is applied to the pilot valve spool. A feedback pressure is applied to piston means on or associated with the spool to apply a force thereto in opposition to the first-mentioned force. For pressure control a pressure sensing means produces a pressure difference equal to the pressure difference between the higher and lower operating pressures of the actuator. For flow control a flow sensor produces a feedback pressure differential dependent on the flow of fluid to the actuator. Pressure and flow control can be optionally obtained by providing two pilot valves in series, one responsive to the pressure sensing means and the other responsive to the flow sensor. One of the pilot valves is set to override the feedback signal thereto, whereby the other pilot valve becomes effective as desired.

摘要： An optical ''''head-up'''' display system for use in aircraft comprises an information display formed by an illuminated fiber optic bundle in a graticule box mounted below the windscreen of the aircraft. An optical projection system comprising a spherical mirror mounted above the windscreen and a semi-reflecting mirror reflect the display to be seen by the pilot superimposed on his view through the windscreen. The display is stabilized in roll by rotating the graticule, and is stabilized in pitch either by moving the semi-reflecting mirror or by moving the relevant part of the graticule.
