Title: Improvements in and relating to aircraft-sustaining rotor blades
IPC: B64C27/46
Filed: 1948-01-29
Abstract: 652,598. Rotary wing aircraft. AUTOGIRO CO. OF AMERICA. Jan. 29, 1948, No. 7005/50. Convention date, Dec. 9, 1939. Divided out of 652,533. [Class 4] A pitch control mechanism for aircraft rotor blades which have freedom for flapping but not for rotation about their spanwise axes, comprises a movable flap mounted on the trailing edge of each blade operated by mechanism for varying the flap settings and thereby varying the virtual pitch angles of the blades, and in which the control moment for varying the setting of the flap is applied at the inboard end thereof, the outboard end being subjected to a partial or complete torsional restraint, so that the flap deflection due to a given displacement of the control mechanism, decreases from the inboard to the outboard end of the flap. The blade 9 is mounted for flapping movement on a pivot 10 attached to the rotor head 5. A flap 11 is mounted on, and rigidly secured to, a torque tube adjacent the trailing edge of the blade, to which the tube is pivotally secured by hinges 13, 14. The hinges 13 are unrestrained whereas the bearing 14 comprises a housing attached to the trailing edge of the blade and encloses a rubber sleeve adapted to receive an extension of reduced diameter formed on the end of the tube 12. The inboard end of the tube 12 is connected to a pitch control arm 15 associated with a swash-plate pitchvarying mechanism, whereby movement of the lever 15 will result in greater angular deflection of the inboard end than the outboard end of the flap due to the restraining influence of the hinge 14.

Title: Improvements relating to controllers for electric motors driving railway locomotives and locomotive vehicles
IPC: B60L3/02
Filed: 1946-03-11
Abstract: 609,271. Controllers. LONDON MIDLAND & SCOTTISH RAILWAY CO., and LORD, J. K. March 11, 1946, No. 7467. [Class 38 (iii)] A controller for an electric motor driving a vehicle comprises a locking means associated with the forward-reverse control device and with the brake system of the vehicle and adapted for permitting the said device to be moved to a neutral position, during motion of the vehicle, only when the brakes have been applied. As shown, the controller comprises a forward-reverse key 1, to which is fixed a spindle 3, and a handle 2 of the dead-man's type. When the key is in the neutral position, a tooth 19 on a latch lever 14 rests upon the upper face of a segment 11 which is carried on the spindle 3. Movement of the key to an operative position places the tooth 19 in one of two notches in the segment 11 and locks the key in that position. Return of the key to the neutral position can only be effected by application of the pneumatic vehicle brake, whereby pressure is applied to a diaphragm to actuate a rod which tilts the lever 14 against a spring- bias and raises the tooth 19 out of the notch. The driver cannot, therefore, render the safety feature provided by the dead-man's handle ineffective during coasting by using the reverser key to disconnect the motor during that period. Preferably, the handle 1 can only be released by the application of maximum braking air pressure. In a modification, a small piston replaces the diaphragm which is subjected to the braking air pressure. The lever 14 may or may not be spring-loaded in this instance.
