Abstract: A wildlife repellant unit is provided which is constructed of a substantially cylindrical tube having a cavity therein into which chemical repellant is placed, further having a barrier positioned inside the cavity to restrain the chemical wildlife repellant from deteriorating until activation, and further including a pair of openings positioned above the barrier to facilitate movement of air, thereby distributing the repulsive odors of the chemical repellant once the unit is activated. The body of the wildlife repellant unit may be constructed of a strong yet pliable material such as rubber or plastic so that, when it is pressed between the thumb and the forefinger, the barrier can be broken and the wildlife repellent unit activated. A clip is also provided to facilitate attachment of the wildlife repellant unit to a limb of a tree, thereby facilitating use of the wildlife repellant unit.

Abstract: A method for coating a concrete substrate with a layer of ethylene-vinyl acetate copolymer latex, which forms a protective skin on the surface of the substrate.

Abstract: A distributing device for solid particles of material, such as gravel, seeds, or similar material in the form of small solids to be delivered to containers. The device consists of a four-legged rectangular frame beneath which a rack carrying the containers may be positioned. The frame carries a rectangular bin in which an apertured fixed bottom plate and a similarly apertured top plate are fitted, the apertures of the bottom plate being longitudinally offset relative to the corresponding apertures of the top plate, with a slidable apertured middle plate disposed therebetween, operated by a manual lever arranged to move the middle plate from a receiving position with its apertures registering with those of the top plate to a discharge position with its apertures registering with those of the bottom plate. The rack holds the containers in a configuration such that the containers can be placed in vertical registry with the apertures of the bottom plate.

Abstract: A cylindrical discharge manifold for an electrostatic gas-dynamic discharge ystem in a helicopter comprising four symmetrically positioned air outlets set in the end of a tubular manifold casing which protrudes out from the helicopter fuselage. The outlets connect to a central high-velocity air-stream inlet pipe in the casing by way of a plurality of air passages extending radially outward from the central inlet pipe. This manifold design insures a symmetrical air distribution, significantly reduces drag pressure on the aircraft, and obviates the requirement for "Y" air hose connections.
