Abstract
772,908. Wind motors. ALLGAIERWERKE, GES. July 19, 1955, No. 20840/55. Addition to 730,060. Class 110 (3). [Also in Group XXXV] In a wind motor in accordance with the parent Specification, having adjustable rotor vanes 2 which, at seat, are biased to a starting fraction by a stressed spring 18 which is further stressed by liquid pressure when the motor is operating, the liquid pressure can be relieved by an electromagnetically operated valve 43 arranged in a connection leading back from the working cylinder 38 to the sump from which the motor driven pump 23 draws the pressure liquid. The solenoid 49 operating the valve is arranged in a circuit with a closure switch 50 controlled by a relay arranged across a Wheatstone bridge spanning a battery 49 working in conjunction with the wind motor and comprising lamps 53, a fixed adjustable resistance 54, and a potentiometer 55.
