Abstract: A first signal generating apparatus generates unit angular signals at predetermined angular intervals, in relation to the revolution of a first rotary shaft. The first signal generating apparatus generates a first reference signal which has a different timing than that of the unit angular signals. A second rotary shaft completes one revolution while the first rotary shaft completes two revolutions.

An angular detecting apparatus determines whether or not the second reference signal is generated by the second signal generating apparatus. Based on the result of this inquiry, the angular detecting apparatus measures the rotational or angular displacement of the first rotary shaft.

Abstract: A digital capacitive accelerometer is disclosed as having a fixed plate mounted on a support member and a sprung plate resiliently mounted in spaced relationship to the fixed plate to form a capacitor. A voltage is connected across the plates to establish an electrostatic force that pulls the sprung plate toward the fixed plate. The voltage is incrementally increased, pulling the sprung plate incrementally toward the fixed plate. When a pull-in voltage level is reached, the electrostatic force is of sufficient magnitude to abruptly pull the sprung plate across the remaining distance separating it from the fixed plate, and a pull-in detection signal is generated by detecting a current pulse as the gap collapses. The plates are then released, and another incrementing cycle is initiated. The pull-in voltage is a function of the initial capacitor gap which in turn is determined by the acceleration the device is experiencing.

Abstract: A mass through-flow is continuously measured by measuring the Coriolis forces that are caused by the mass flow passing through a winged wheel. The mass flow is introduced centrally onto the winged wheel which rotates with a constant r.p.m. and diverts the mass flow radially outwardly. The Coriolis forces and thus the corresponding reaction torques which are proportional to the mass through-flow are measured with the aid of a torque joint interposed between a housing of the winged wheel and a drive motor for the shaft that drives the wheel. Force sensor elements, preferably in the form of bending beams, are incorporated into the torque joint and are deflected by the reaction torque moment applied to the motor housing. These bending beams provide an output signal that is proportional to the mass through-flow through the apparatus.

A feed tank is connected to a liquid transfer jet powered by a pumping chamber pressurized by compressed air. The liquid is pumped upwardly into a sampling jet of a venturi design having a lumen with an inlet, an outlet, a constricted middle portion, and a port located above the constricted middle portion.
