Abstract
A disposable apparatus for propelling particulate matter against a surface of a target material includes, a mixing chamber having a chamber wall, a multi-conduit receiving port, a propellant-gas receiving conduit, a discharge conduit, and a flow through conduit. The gas delivery conduit extends from the propellant-gas receiving port into the chamber, a mixture discharge conduit extending from the mixture discharge port into the chamber, and a quantity of particulate matter inside the chamber. The flow through conduit(s) provide a means for transferring flow from the multi-conduit receiving port through the discharge wall to exit proximate the exit of the discharge port. A method is provided for propelling particulate matter against a surface of a target material using the above-described apparatus, including the steps of delivering a stream of gas into the air delivery conduit and into the mixing chamber from the gas source, so that the gas stream blows through the quantity of particulate matter, causing the particulate matter to mix with the gas stream, forming a gas and particle mixture, and discharging the mixture through the discharge conduit and the discharge port to strike th…
