Title: Improvements in or relating to aircraft control mechanism
IPC: B64C13/00
Filed: 1953-05-13
Abstract: 758,646. Controlling aircraft. AERO DESIGNS, Ltd., and SUPPANCIC, G. O. Aug. 11, 1954 [May 13, 1953], No. 13380/53. Class 4. The degree of " feel " imposed on a control operating member for operating a control surface or the gear ratio between a control member and a control surface on aircraft is made responsive to or varied by the strain which is imposed on the aircraft structure by operation of such surface. A control column 36 rotates a shaft 35 through gears 37-40 to control an elevator servomotor (not shown). The shaft 35 is made in two parts connected at their ends by a splined sleeve 41 and fixed collars 42, 43 are mounted on the shafts and co-operate with sliding elements on toggle links 44, 45 connected by a linkage 46, 47, 48 to a lever 32 on a " feel " imposing mechanism. The control column 36 is connected also by a rod 49 to the " feel " mechanism which comprises a lever 10 connected by an anti-torque linkage 12, 15 to a fixed part 18 and a fork 19 which is mounted in the lever 10 for relative pivotal movement about its longitudinal axis and constitutes one fork of a Hooke's joint, the other fork 28 being pivotally mounted at 29 in the part 18 and formed with the lever 32. The cruciform element of the joint comprises a member 23 pivoted in fork 19 and a member 25 pivoted in fork 28, the members 25 and 23 being connected by a bonded flexible sleeve 33. With the parts in the position shown in Fig. 1 the mechanism offers no restraint to movement of the control column 36, but if the control run 35 extends as a result of fuselage deflection caused by air loads on a deflected elevator the linkage 44-48 will operate lever 32 to rotate the fork 28 so that rocking movement of lever 10 is resisted by spear deflection of the sleeve 33. An hydraulically or electricallyoperated actuator 50 may be inserted in the control run 35 to vary the length of the rod 48 to operate the " feel " mechanism in response to variations in dynamic head. Instead of the mechanical linkage described strain gauges may be used to control the operation of the " feel " mechanism. It is stated that link 48 may be coupled to lever 35 of the mechanism described in Specification 677,439, whereby the deflection angle of the control surface may be adjusted in response to strain in the aircraft structure. Specification 656,217 also is referred to.

Title: Pressure sealing means for valves
IPC: F16K11/085
Filed: 1947-05-21
Abstract: 638,017. Rotary-cylindrical valves; nozzles. PROUT, E. W. May 21, 1947, No. 13693. Convention date, March 4, 1946. [Classes 69 (iii) and 135] In a valve, e.g. a fire-fighting valve having multiple nozzles, a tubular element in the discharge passageway is movable axially towards the cylindrical valve closure member by liquid pressure acting against sealing means preventing passage of liquid around the outer end of the element, so that the inner end seals the member. Water may be discharged through the valve rotor 5, Fig. 1, to the main nozzle 3 or, on turning the rotor by the handle 6, through the passage 8, rotor passage 7 and passage 9 leading to a fog nozzle. Each outlet from the rotor chamber 4 is counterbored at 11, Fig. 2, to accommodate a ring 13 having at one end a surface 15 for sealing with the rotor and at the other end a lip 16 entering a step 12. In the cavity 17 between a shoulder at the base of the lip and a shoulder at the base of the counterbore fits a resilient channel-shaped sealing ring 18. Pressure acts in the channel, because of clearance afforded between the ring 13 and its bore 11 and between the rotor and its chamber, to urge the ring towards the rotor. When the valve is open the sealing pressure is reduced by the venturi effect of the high velocity flow through the nozzle so that the rotor may be easily turned.
