A powder feed assembly comprises a powder hopper, a motor, an auger housing, an auger, a porous gas-permeable powder filter, a carrier gas inlet, an auger sleeve, and a powder hose.

A powder feed assembly comprises a powder hopper, a motor, an auger housing, an auger, a porous gas-permeable powder filter, a carrier gas inlet, an auger sleeve, and a powder hose. The auger housing receives a powder from the opening in the hopper floor into a powder chamber defined in the auger housing. The auger is selectively rotatable to propel the powder from the powder chamber past the distal end of the auger and into the auger sleeve. The carrier gas inlet introduces carrier gas into an inner chamber of the auger housing. The wall of the auger sleeve allows at least some of the carrier gas to flow or permeate into the internal bore of the auger sleeve to pick up and carry the propelled powder out of the auger housing. The powder hose directs the carrier gas and carried powder from the auger housing to a powder dispenser.

1. A powder feed assembly comprising: a powder hopper having a wall, a lid, and a sloped floor together forming a chamber, and having an opening defined in the floor;a motor within a motor chamber defined in a motor housing, the motor having a selectively rotatable shaft connected to an auger holder
1. A powder feed assembly comprising: a powder hopper having a wall, a lid, and a sloped floor together forming a chamber, and having an opening defined in the floor;a motor within a motor chamber defined in a motor housing, the motor having a selectively rotatable shaft connected to an auger holder;an auger housing positioned to receive a powder from the opening in the hopper floor into a corresponding powder chamber defined in the auger housing, the motor housing being affixed to the auger housing, the auger housing defining (i) a first auger bore providing an opening between the motor chamber and the powder chamber and (ii) a second auger bore providing an opening between the powder chamber and an inner chamber defined in the auger housing;an auger at least partially within the auger housing, the auger having a proximal end and a distal end, the auger having a shaft and a spiral blade projecting from the shaft, the proximal end of the auger protruding through the first auger bore and connecting to the auger holder and the distal end of the auger protruding at least partly through the second auger bore such that the auger is selectively rotatable to propel the powder from the powder chamber past the distal end of the auger when the auger is selectively rotated;a porous gas-permeable powder filter positioned within the powder chamber and shaped such that a circumferential cavity is defined around the powder filter, the circumferential cavity being fluidly connected via a carrier gas release bore to the inner chamber of the auger housing;a carrier gas inlet affixed to the auger housing for receiving a carrier gas and introducing the carrier gas into the inner chamber of the auger housing;an auger sleeve within the auger housing and positioned at least partially within the inner chamber, the auger sleeve having a wall defining an internal bore positioned to receive the distal end of the auger and therefore the propelled powder, at least a portion of the wall of the auger sleeve past the distal end of the auger allows at least some of the carrier gas to flow or permeate through the auger sleeve wall and into the internal bore of the auger sleeve to pick up and carry the propelled powder out of the auger housing; anda powder hose for directing the carrier gas and carried powder from the auger housing to a powder dispenser, the powder hose having a distal end adapted to be connected to the powder dispenser and a proximal end connected to the auger housing. 2. The assembly of claim 1, wherein a plurality of openings are defined in the wall of the auger sleeve. 3. The assembly of claim 1, wherein the auger sleeve is made from a porous gas-permeable material. 4. The assembly of claim 3, further comprising an additional solid auger sleeve positioned within at least portion of the internal bore of the auger sleeve, the solid auger sleeve positioned to receive the distal end of the auger. 5. The assembly of claim 4, wherein the solid auger sleeve comprises a cylindrical wall having a plurality of openings defined in the wall past the distal end of the auger. 6. The assembly of claim 1, wherein the powder hose is connected to the auger housing via the auger sleeve. 7. The assembly of claim 1, further comprising: a first carrier gas tube fluidly connecting the inner chamber of the auger housing to the chamber of the powder hopper such that carrier gas can move freely between the inner chamber of the auger housing and the chamber of the powder hopper; anda second carrier gas tube fluidly connecting the inner chamber of the auger housing to an inner chamber of the motor housing such that carrier gas can move freely between the inner chamber of the auger housing and the inner chamber of the motor housing.
