Abstract: A system and apparatus therefor for the removal and destruction of harmful toxic polychlorinated biphenyls (PCBs) from a fluid, such as electrical transformer oil. The contaminated fluid is pumped through heating equipment to raise its temperature to a predetermined level prior to it being fed into a mixing chamber. An injector mechanism feeds a predetermined quantity of a reagent, such as an elemental sodium dispersion, into the mixing chamber where a power-driven impeller thoroughly mixes the two fluids. This mixture is fed into a reaction zone, preferably consisting of a plurality of closely nested back-and-forth tubes of a predetermined length and cross-sectional area wherein a chemical reaction occurs between the PCB-fluid and reagent forming harmless by-products which are insoluable in the now decontaminated fluid. The solid by-products are removed in a separator, such as a filtering medium or centrifuge, and any gases and water vapor are removed in a deep vacuum degasser.

Abstract: A system for producing hot water for a residential dwelling by recovering heat from the hot combustion gases in the flue and chimney of the dwelling's heating system.

Abstract: A control system for automatically adding and subtracting capacitors to and from an electrical supply line for regulating the power factor of the supply line. A three-phase transducer is connected to the supply line and supplies a signal in direct proportion to the VARs of the supply line to a double setpoint meter relay. The meter relay is connected to a pair of timing relays which are selectively energized in response to a capacitor "add" or "subtract" signal from the transducer. If the signal is maintained for a predetermined period of time on one of the timing relays, a motor of a respective "add" or "subtract" cam-actuated switch is activated. The cam switches are programmed to energize or deenergize control relays, which in turn actuate capacitor contactors to add or subtract the next available capacitor.
