Abstract: A symmetrically balanced, integrated, portable, refillable, serviceable, adjustable, self contained tool, suitable for single hand operation, for ejecting a stream of particulate, powdered, or liquid material toward a target combining a supply reservoir containing the materials, a portable propellant container adapted to the supply reservoir, carrying compressed propellant liquid, a propellant release valve delivering propellant from the container via a constricted air jet orifice to a angular mixing chamber positioned above the uppermost level of materials the materials supply reservoir, a delivery conduit connecting the lower portion of the supply materials reservoir chamber to the angular mixing chamber through an adjustment valve, delivering a stream of materials aspirated from the materials supply reservoir by the negative atmospheric pressure deferential created by a Venturi effect to the angular mixing chamber, driving the compressed gas and materials through the connected nozzle containing a cylindric

Abstract: A symmetrically balanced unitary portable self-contained tool, suitable for single-hand operation, for ejecting a stream of granular particles toward a target sit combines a supply hopper containing the granular particles, a portable propellant container carrying compressed propellant liquid, a propellant release valve delivering propellant from the container via a constricted Venturi orifice to a mixing chamber positioned above the uppermost level of particles in the hopper, a delivery conduit connecting the lower portion of the supply hopper to the mixing chamber, and a nozzle connected to deliver a stream of granular particles aspirated from the supply hopper through the mixing chamber by the negative pressure differential created at the Venturi orifice.
