Abstract: An asynchronous alternating current motor/generator having an armature winding which includes interspersed energy coils and reflux coils which are electrically and inductively isolated from each other, but which are paramutually inductively coupled through the rotor. Each reflux coil is positioned at 90 electrical degrees to the adjacent energy coil and is tuned to minimize the inductive reactance of the motor/generator.

Abstract: The present invention relates to a bio-catalytic oxidation reactor for remediation of organic wastes and more particularly to a bio-reactor for optimizing the process of oxidation reduction, or composting, of organic wastes or by-products. The reactor includes an elongated cylindrical vessel supported for rotation and includes loading and discharge chutes mounted on the ends of the vessel which include feed assemblies mounted to the vessel end plates such that the feed assemblies rotate when the vessel rotates.

Abstract: The present invention is applicable to any a.c. electromagnetic reduction device which is used to change voltage or current levels or to transfer energy between mechanical and electrical systems and includes, for each phase, a combined pair of windings which are conductively and inductively dependent. The dominant winding of each combined pair is electrically connected to an input/output phase, while the reflux winding of each pair is electrically connected in additive or subtractive series with the dominant winding by means of a variable capacitive reactance. The capacitive reactance is then adjusted to minimize the net reactive factor of the coupled windings and the net reflected impedance of the input/output circuitry.

The apparatus includes a string guide which is adapted to bear against a tuned string of the instrument, reciprocating means adapted to be mounted on the peghead of the instrument and secured to the string guide, and an actuator operatively connected to the reciprocating means for selectively moving the string guide to "bend" the associated string and increase the tension thereon a predetermined amount.

Abstract: Single and polyphase a.c. induction devices, such as: motors, generators, transformers, welders, ballasts, etc. are so wound as to maximize performance and efficiency. For each phase of such device this invention utilizes a combined pair of windings which are conductively and inductively dependent. An energy supply winding of each combined pair is electrically connected to a corresponding input/output phase, while the remaining, or reflux, winding of each pair is electrically connected in series with a tunable capacitive element and to neutral or electrical ground by means of a linear and non-linear resistive means.

Abstract: The present invention provides means to instantaneously optimize reactive kva for an a.c. power system containing both linear and non-linear reactive loads. The preferred means utilizes a reflux transformer which is tuned for maximum energy transfer between primary and secondary windings. Each secondary winding is connected in series with a variable inductor and a fixed capacitive means, so as to continuously reflect variable reactive kva to the power system via the primary and secondary windings. The reactive kva requirements of the power system can thus be continuously optimized without destructive voltage transients associated with switching graduated units of fixed capacitive compensation or incurring the risk of conducting series resonant currents associated with non-linear loads.

Abstract: The present invention offers improvement of performance and efficiency of a compact fluorescent lamp by means of a series tuned LRC ballasting circuit. The resonant voltage rise in the circuit is utilized to increase the cyclic crest voltage necessary for lamp ionization. After ionization occurs, lamp current and power are clamped and regulated by the lower Q factor of the tuned circuit. The LRC circuit provides a square wave of voltage across the lamp with considerable reduction in noise and RF ringing. Since it is a tuned circuit, it operates at approximately unity power factor, at lower temperature, and with a net equivalent impedance that provides for maximum illumination, lamp life and efficiency.
