Abstract: An arc reactor device for producing nitrogen oxides by an arc discharge process includes an electrically conductive casing, defining an arc discharge chamber therein, and an electrically conductive discharge electrode electrically insulated from the casing and extending into the chamber. An arc discharge potential is applied between the discharge electrode and the casing to produce electrical arcing. A starter electrode extends into the chamber and is movable from an extended position in which it contacts the discharge electrode, to a retracted position, in which the starter electrode is out of contact with the discharge electrode. A means for moving the starter electrode from the extended position, at initiation of operation, to the retracted position and maintaining the starter electrode in the retracted position during operation of the arc reactor device includes a solenoid actuator. Air is supplied to the electrically conductive casing from several manifolds which surround the casing.

Abstract: An ultramicrotome has a chuck for holding a specimen block and a stationary knife assembly. A radioactive means is mounted on the ultramicrotome for discharging static electric charge on the chuck, the specimen, and the knife assembly.

Abstract: A method and apparatus for home production and application of fixed nitrogen fertilizer uses an arc discharge process to ionize nitrogen and oxygen and form nitrogen oxides. These nitrogen oxides are injected into water supplied by a garden hose to a yard or garden. The device is compact, economical and requires no raw materials except air to produce the fixed nitrogen. The device may operate on ordinary 60 cycles, 110 volt power.

Abstract: A method for promoting the photooxidative destruction of organic waste pollutants by use of gelled metal alginate particles which have been stained with a dye sensitizer. The stained particles are both recoverable and biodegradable. They are effective in promoting the photooxidation of organic wastes including toxic phenol compounds in the presence of visible light and atmospheric oxygen.
