Abstract: This disclosure describes a method and apparatus for using a single sensor to determine the relative velocity between an object and a fluid stream, the average temperature, pressure and/or density of the fluid stream, and thereby the mass flow of the fluid stream. Select properties of a signal, such as a sonic signal, directed through a vortex street are detected using modifications of existing single sensor vortex volumetric flowmeter methods and apparatus. The modifications facilitate the measurement of mass flow by measurements of the relative energy of the signal and the temperature of the fluid as ascertained from the time delay in signal passage from a signal directing means (43) to a signal receiving means (45).

The free gyro motor drive circuit includes a first sensing means for generating a up-down sinusoidal position signal and a second sensing means for generating a right-left sinusoidal position signal, both sinusoidal position signals having a frequency corresponding to the rotational speed of the gyro motor.

Similarly, the direct current error signal is fed into a second speed control circuit means along with the right-left sinusoidal position signal to produce a right-left motor control signal. The up-down motor control signal drives a pair of up-down motor coils in the free gyro motor, and the right-left motor control signal drives a pair of right-left motor coils in the free gyro motor.

Abstract: A fluid pressure actuator which locks in the extended position. The lock is a roller operated, dual segment pawl mechanism that unlocks in response to a pressure difference between extend and retract pressures. The two lock segments, chamfered for engagement with the cylinder end, are in diametrically opposed slots in the actuator piston head. A cylindrical section projects from the segment portion.
