Abstract: An electrostatic charge generator for continually providing charge carriers f a given polarity in a flow of dielectric fluid. The charge generator comprises a coaxial tube with an inner conductor wire coaxial with a hollow, cylindrical outer conductor. A D.C. potential is applied between the inner and outer conductors of the coaxial tube and a dielectric liquid, such as oil, is caused to flow therethrough. Since the intensity of the non-uniform electric field in the conductor tube is highest near the inner conductor, the electrostatic charges of the opposite polarity as the inner conductor are removed from the dielectric fluid faster than charges of the same polarity are removed at the outer conductor. This results in the dielectric fluid exiting the conductor tube carrying a charge of the remaining polarity.

Abstract: A system for measuring the transfer immitances, impedance and admittance, a linear electrical network having one or more ports. The system utilizes clamp-on ferromagnetic cores to electromagnetically couple the transfer immitance measuring system to the electrical network without having to interrupt the normal on-line operation of the electrical network. A high frequency injection network, which includes a high frequency signal generator and a multichannel amplifier, injects a high frequency signal into each of the ports of the electrical network. High frequency voltage and current measuring networks are electromagnetically coupled to each of the ports of the electrical network to measure the high frequency component of the port voltage and the port current.

Abstract: An electrostatic high potential device which utilizes the generation of etrostatic charges on moving oil to produce a high potential difference on the order of thousands of volts. A metal encased ionizing device or charge generator with a system of passageways of dielectric material has an oil moving therethrough and against the dielectric material to cause a transfer of electric charges between the oil and passageway surfaces. The passageways act as baffles and provide a large amount of surface contact between the oil and dielectric material. The conductive housing of the ionizing device is grounded to draw off the charges on the dielectric material, and a pump circulates the charged oil from the ionizing device to a charge storage device of similar design. Electrodes in the charge storage device draw off the charges on the oil.

Abstract: A parametric energy coupling system for providing uninterruptible a-c power o electrical loads. In a normal mode, a parametric transformer couples a-c line power directly from an a-c power source to a load. Upon a power outage occurrence, an inverter is energized whereby a-c power is generated from a d-c source and applied to the load.
