Abstract: A hazardou waste incinerator which utilizes a cyclotron resonance plasma. The plasma is generated by introducing vaporized hazardous material and a feed gas into a vacuum chamber. The chamber has a magnetic field source and an electromagnetic radiation source. The cyclotron resonance plasma is produced by the resonance that occurs when the frequency of the electromagnetic radiation is set equal to that of the gyration of electrons or other charged particles in the magnetic field according to the formula: F.sub.res =(1/2.pi.)(qB/m) hertz Where q is the charge of the electron or ion, B is the strength of the magnetic field and m is the mass of the electron or ion. The strength of the electromagnetic radiation is adjusted so that the flowing gases are ionized, forming a plasma. During the reaction, the charged particles collide with neutral particles, providing both ionization and fragmentation (the breaking up of high-mass molecules into lower mass fragments).

Abstract: A contact operating mechanism is disclosed which employs a hydraulic motor means for moving contact members between closed and tripped positions, an accumulator for supplying hydraulic fluid under pressure to the motor means, and a separate gas supply means in fluid communication with the accumulator. The accumulator includes a piston or separating means for dividing the interior of the accumulator into two separate pressure chambers. One of the pressure chambers is connected to the hydraulic motor means and the other is connected to the gas supply means. Preferably, the gas supply means is separately disposed from and permanently connected to the accumulator with a sufficient volume of pressurized gas such that in the event that the piston repositions so as to completely fill the accumulator with hydraulic fluid sufficient gas under pressure is available to stroke the accumulator piston and operate the motor means.

Abstract: A multiple element current limiting fuse has a plurality of tube fuses soldered at opposite ends to a pair of metallic end bells having blade-like terminals for connection to busbars of an external electrical circuit. Fasteners having the general dimensions of the tube fuses are also mounted between the end bells and connectors, such as, studs or rivets are formed on ferrules at opposite ends of the fasteners to mechanically couple the fasteners to the end bells and preserve the spacing between the end bells even when the fuse is subjected to tensile forces and elevated temperatures efficient to soften the solder. The use of a hollow ceramic body and hollow connectors at the ends of the fasteners permits the passage of coolant through the fasteners for cooling the multiple element fuse.
