Abstract: The present invention provides a valve control apparatus which can be programmed to deliver a desired flow of gas. A valve 22 is connected to a stepper motor 28 which is controlled by a computer 32 to open or close the valve in steps within a gas flow line 24 to deliver a desired rate of flow. A flowmeter 30 is provided along the gas flow line 24 for measuring the flow and inputting this flow to the computer 32. The computer 32 calculates rate of flow information obtained from the flowmeter 30 and controls the stepper motor 28 to open or close the valve 22 as necessary in accordance with the received rate of flow information and a desired rate of flow preprogrammed into the computer 32. As a result, a precise desired rate of flow can be obtained. Also, position indicators 34 may be added to the valve 22 to indicate when the valve 22 is completely open or completely closed. The valve 22 may be provided with a return spring 36 to automatically close the valve 22 in the event of a power loss. The computer 32 may be programmed to detect a significant increase in the rate of gas flow being closing the valve 22 accordingly. Additionally, a pressure switch 38 may be provided along the gas flow line 24 to cause the valve 22 to close upon a pressure change. Finally, temperature 40 and pressure 42 sensors may be added along the gas flow line so that the computer 32 can calculate and maintain a specific mass flow of gas.

Abstract: A method for monitoring turbine blade vibrations comprises the step of transmitting a continuous wave of microwave energy toward a rotating row of blades. Each passage of an individual blade tip through the path of the continuous wave produces a signal indicative of the time at which each passage occurs. The signal is then monitored and analyzed to detect blade vibrations. The signal can be based on a standing wave or a reflected wave.

Abstract: A multiplex bus interface enables power and data to be transmitted and received on a two wire bus. Input and output devices operate with transceivers connected to the bus to communicate with each other by placing their data on the bus within specific time slots controlled by a controller, a clock module which broadcasts data to all connected transceivers. A pulsed power waveform provides power to the transceivers and data through pulse width modulation of the pulsed waveform. Data from the transceivers is transmitted during a time slot between power pulses. Data integrity is checked by the initiating input transceiver. Errors are reported at the end of a broadcast cycle. Output transceivers use the data as appropriate for the device and condition being monitored or controlled.

Abstract: A rocker styled switch includes an arm member moveable into and out of a beam path transmitting light between an optical transmitter and an optical receiver for blocking and allowing light to reach the receiver for providing an actuating signal. An end of the arm member includes a cam follower moveable along a contoured cam surface for causing a preferential movement of the arm member from an unstable position to a stable position responsive to the cam surface for defining a switching operation. Interchangeable cam surfaces provide a one position momentary switch, a two position momentary switch, a two position stationary switch, and a three position stationary switch.

Abstract: A pressure sensor includes an optical transmitter transmitting a dispersive light toward two optical receivers, all carried in a housing. Pressure changes on the housing cause the light beam to be deflected with the amount of deflection measured by the difference in light received by each of the two receivers. A processor operable with the receivers provides a pressure measurement responsive to the light beam deflection.
