Abstract: Apparatus and method for controlling volatile organic compounds and air toxics in a contaminated fluid flow through use of an excited species flow generated and introduced into the contaminated fluid flow to convert the contaminants into non-toxic compounds. Tungsten electrodes and an alternating current are used in the excited species generator.

Abstract: A method of diminishing the amount of chlorinated organics released to the atmosphere in the incineration of wastes which includes injecting calcium-based sorbents into the flue gas to react with HCl to form calcium-chlorine compounds to remove the HCl from the flue gas and prevent it from forming the chlorinated organics. The flue gas carries the sorbent from the injection zone to the reactive temperature zone quickly enough such that the sorbent is not exposed to temperatures which would degrade the effectiveness of the sorbent, the reactive temperature zone being in the range of 300.degree. C. to 900.degree. C.

Abstract: An accelerated wear and fatigue tester for replacement human heart valves includes a fluid which is caused to pulse the heart valve by a pressure generator utilizing a coil secured to a flexible diaphragm in contact with the fluid. The coil is subjected to a magnetic field and a signal selected from pulsed, sinusoidal, or random pulses and/or a DC offset, or a recorded signal from a human heart, such that the magnetic interaction selectively pulses the diaphragm and replacement heart valve to simulate heart action. A plurality of pressure generators with differing signals, including phase differences, may be provided to simulate arrhythmia in a heartbeat, and a library of recordings may be used as a database to predict irregularities in replacement heart valves.

Abstract: A method and apparatus for testing the proper operation of the optical elements in the optical detection circuit of an electronic register in an energy meter. The light emitter circuit is periodically pulsed adequately to turn the emitters to the on condition, and a comparison circuit is provided in which the voltage across a monitor point in circuit with the light emitters and a switching circuit is monitored both before and after each pulse. The absence of a voltage change upon pulsing the light emitter circuitry is used to generate a first error or failure signal. The light detector is read prior to each pulse to determine if unprogrammed light is being received prior to the pulsing of the light emitter as an indication of tampering with the accurate reading of the energy meter, and a second error signal is generated in response to unprogrammed light.

Abstract: An electronic register in an electric energy meter includes a power supply transformer mounted on and through the register circuit board which is positioned between the base of the meter and the register indicator. Shrouds isolate and insulate the connections within the shrouds to the primary winding of the transformer, and positioning members are provided to secure the transformer to the circuit board while at the same time providing positioning for the secondary winding terminal pins which pass through the circuit board to enable their proper connection, such as by soldering, to the circuit board. A unitary molded bobbin provides a spool for the transformer windings and core, the positioning members, the shrouds, and securing of the secondary winding terminal pins.

Abstract: A method and apparatus for adjustment of the assembly of an electric power meter which rotates in response to power consumption which enables successive test positions to temporarily support the assembly without marking the bearing, and provides only a single mark on the bearing at the final factory adjustment position with an indication on the bearing of any subsequent tampering with that position.
