Title: Improvements in or relating to profile recording and comparing apparatus
Inventor: HILL WILLIAM GEORGE
IPC: G01B5/20
Filed: 1961-11-03
Abstract: 949,104. Comparing profiles; recording apparatus. SECRETARY OF STATE, WAR DEPARTMENT. Nov. 2,1962 [Nov.3, 1961], No. 39409/61. Headings G1J and G1M. Apparatus for recording and comparing profiles comprises a feeler 21 movable round a standard or a workpiece 43. As the feeler moves in one co-ordinate direction rod 18,19 slides in members 22, 23 and drives a wheel 17 to rotate a cylinder 16. As the feeler moves in a perpendicular direction carriage 4, supporting cylinder 16, rod 19 and members 22, 23 slides on guides 11, 8, 9, thus moving cylinder 16 axially relative to a support 33, carrying an optical system and a scriber. Cylinder 16 is transparent but covered with a film of carbon. A scriber 37 is detachably mounted on a fixed support 33 and bears resiliently against cylinder 16 so that it can produce a trace of a standard profile 43 on the cylinder 16. An optical system (Fig. 3) comprising a light bulb 40a, a mirror 42, within the cylinder 16, a lens 46 and mirrors 47, 48 are provided so that the trace produced can be viewed on a screen 49, with a reference marking 50, mounted on the same support 33 as the scriber 37. If the scriber is removed and the feeler 21 again moved round the standard 43 the trace will move through the intersection of the reference marking 50. If a workpiece replaces the standard 43 and the feeler follows its outline any deviation of the trace from the intersection of marking 50 indicates deviation of the workpiece from standard. In alternative embodiments the cylinder 16 is coated with a reflecting material and an appropriate optical system provided. The axial movement of the cylinder relative to the optical system may be produced by moving the optical system rather than the cylinder. The cylinder may be replaced by a turntable. The trace produced on the cylinder or turntable need not be identical to the standard profile but is related thereto by the transmission characteristics of the apparatus.

The wear plate is of figure-of-eight shape loosely fitting the pump housing and abutting an end wall 12 of the pump housing with grooves 29, Fig. 3, extending from a groove 27 communicating with the inlet passage 15 on the face of plate facing the end wall 12 and grooves 30 extending from the outlet passage 16 on the face of the plate facing the gears so that the unbalanced fluid pressure forces acting on the plate urges it against the end wall to prevent movement of the plate. The wear plate may be formed with a bevel 33 extending from the outlet passage on the face of the plate facing the gears to provide extra surface area on which pump discharge pressure acts to urge the plate against the pumping chamber in the region of the pump inlet. Instead of the grooves 29 being formed in the wear plate they may be formed in the end wall 12. A further wear plate may be fitted adjacent the cover (not shown) and the faces of the gears may be coated with a bearing surface of, e.g., silicone or plastics material. The wear plate may be of laminated construction having a bearing facing 26 slidably engaging the gears 17, 21.

Abstract: 1517167 Variable pitch propellers DOWTY ROTOL Ltd 1 Sept 1975 [24 Sept 1974] 41419/74 Heading B7V A control system for a variable pitch propeller comprises an actuator, e.g. a piston 16, urgeable in one direction by biasing means, e.g. spring 21 and counter weights 22, for adjusting the pitch in one sense, and subjectable to fluid pressure in a chamber 20 for movement in the opposite direction against the action of the biasing means, and stops 24 subjectable to the fluid pressure and maintained in an inoperative position when the pressure is above a predetermined value and being movable into an operative position to abut a shoulder 23 when the pressure falls below that value to arrest movement of the piston at a predetermined position, e.g. corresponding to 45 degrees pitch. In operation, if the pressure from a pump P and governor controlled valve V falls, piston 16 is moved by the biasing means against the falling pressure in chamber 20. Pressure is also relaxed on faces 28 of the stops 24 which allow them to be moved radially outwards by centrifugal force to engage the abutment 23. If the pressure falls due to failure of the engine E, as the propeller rotation reduces the centrifugal force will become less effective and the stops will be retracted by springs 27, allowing the piston to move to abut an end 30 of cylinder 18 which corresponds to a maximum feathered position of the blades and least drag on the aircraft to which they are fitted. In Fig. 2, not shown, the pump (114), reservoir (113), governor G<SP>1</SP> and control valve (V<SP>1</SP>) are all located within the propeller hub (112). The speed-responsive governor can be replaced or augmented by a positional control valve. The movement of the stops 24 can be controlled by electro-magnetic means, or independent fluid pressure pilot means, or by suitable mechanical means. The spring 21 can be replaced by a hydraulic device. The engine E can be of the reciprocating or rotary piston kind, or a gas turbine. The actuator can be of the rotary vane type.
