Abstract: A process and apparatus for controlling high vegetative and brush growth along a narrow, continuous strip of land along the sides of a roadway or other right-of-way comprising preparing a dilute aqueous herbicidal solution, particulating said solution into coarse or large droplets and imparting an electrostatic charge to the droplets of herbicidal solution, and spraying the particulated and electrostatically charged droplets of said solution upon a narrow, continuous strip of land along the side of a roadway with minimal encroachment of the spray upon the environmental land adjacent said strip, and apparatus for effectively and accurately performing such operations.

Abstract: An emission control unit is mounted in the exhaust line of a fossil fuel internal combustion engine and includes a tubular housing in which a lime sleeve is received. The sleeve has an axial opening through which a corona wire extends. Exhaust gasses pass through the sleeve along the wire. Placing a charge on the wire drives pollutants in the exhaust laterally outwardly into the sleeve at a direction which is 90.degree. to the direction of exhaust travel. The sleeve chemically interacts with the pollutants and neutralizes them with little hazard to the environment.

Abstract: Apparatus for cleaning a sheet or web while it is being fed. Upper and lower ionized air cleaner units are provided, having spaced, parallel plates providing a throat between which the sheet or web is passed. The throat entry includes diverging flanges, as does the throat exit. Each unit includes first and second spaced rows of ionized air blower holes extending transversely of the sheet or web; between these rows is an air suction slot. The ionized air generator includes a pair of spaced channel, each having its open side closed by a plate having the blower holes therein. An ionized air generator with air boost extends axially within each channel, and has ionizing points extending into the blower holes in the plate. The suction slot is provided between the two channels.A linearly extending hood overlies the suction slot, having at an end thereof a suction outlet.

Abstract: Apparatus for introducing filtered, ionized air into a clean room comprises a HEPA filter unit and a metal ionizing grid unit supported in a frame, secured to the discharge face of the filter unit. A seal is provided between the filter and ionizing grid frame. The apparatus is supported by T-rails, and a seal is provided between the frame and the T-Rails.

Abstract: A gas volume flow gauge is provided with apparatus to ionize the gas being discharged. The gauge has an adjusting valve and a float in a vertical gas passage to indicate the flow rate; an ionizing point is provided in the gas outlet passage, and is capacitively coupled to a conductor connected to an alternating current source. A grounded conductive ring surrounds the ionizing point.

Abstract: A cleaner for circuit boards includes two elongate hollow housings positioned one above the other to provide a slot between two facing walls. Each wall has an aperture therein spaced from its ends, and brushes extending into the slot from the walls, both in advance of and behind the apertures, to restrict air flow to the apertures to entry at the ends of the slot. Ion emitters are carried by each wall, between two brushes in advance of the apertures. Motor driven fans are in the housings to draw air across the printed circuit board and into the apertures. The housings also contain a power supply for the ion emitters and a motor to drive pinch rollers.

Abstract: A miniature flexible air ionizer comprises a first pair of insulating strips having a series of conductive emitters between them, and a second pair of insulating strips having a linear conductor between them and a second linear conductor on that surface of a strip of the second pair which is most remote from the emitter. The emitters and conductors are provided by laminating copper on plastic strips and chemically etching. The emitters are comb-shaped, with teeth having flat ends which are exposed to air and do not extend beyond the strips. An end connector provides mechanical and electrical connections to the ionizer.

Abstract: A static neutralizer which emits ions without emitting light to the environment. The static neutralizer includes a body of insulating light absorbing material, having a cavity therein, with points of ion emitters located in the cavity. A passage leads from the cavity to the exterior, permitting flow of ions from the body and preventing passage of light from the ionizing points to the exterior. A metal sleeve surrounds the insulating material body with a peripheral edge of the metal band and the ionizing points preferably lying in a common plane. A source of electric potential, preferably alternating, is connected to the ion emitters, and the metal sleeve is connected to ground. Preferably, the connections are provided by a shielded cable having an inner conductor connected to the ion emitters, an outer, flexible woven wire shield connected to the metal band, and a light impervious, insulating layer on the exterior of the woven shield.

Abstract: A static electricity suppressor includes a base insulating sheet having conductive patterns coated on its two surfaces, and ion emitters in the form of pointed wires passing through the sheet, the ionizing points of the emitter extending beyond one surface of the base and being spaced from the pattern thereon, which is grounded. The opposite ends of the emitters are coupled to the pattern on the second surface of the base, capacitively or directly, which second surface pattern is connected to electrical source(s).
