Abstract
Abstract A particle accumulator and display having a closed chamber with a plurality of injection nozzles to provide a vortex flow within the chamber. An ejection nozzle is centrally located within the chamber at the end adjacent the injection nozzles. A flow stabilizer is positioned between the injection nozzles and the ejection nozzle. A particle extractor and stabilizer is attached to one end of the closed chamber and has a stabilizer hub and rotating end wall driven by a motor. The particle extractor and stabilizer includes a flow impeller, which communicates with an annular channel between the stabilizer hub and rotating end wall to withdraw the accumulated column of particles from the chamber.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A particle accumulator and test apparatus, comprising a closed chamber; means, including a plurality of input nozzles, for providing a vortex flow of a particle laden gas within the chamber; a gas ejection nozzle spaced from and centrally located at the end of the chamber adjacent the input nozzles; means, positioned between the input nozzles and the ejection nozzle, for stabilizing the flow within the chamber to permit at least one annular column of particles to accumulate within said chamber, means connected to the end of the chamber remote from input nozzles and the ejection nozzle for selectively withdrawing a collected column of particles from said chamber; said means for selectively withdrawing a collected column of particles from said chamber including means for providing a flow stabilizing rotating end wall for said chamber; means for providing a flow stabilizing rotating hub centrally located with respect to the rotating end wall; said means for selectively withdrawing a collected column of particles from said chamber including a particle outlet means; a flow channel between said rotating hub and said rotating end wall and a flow impeller for drawing collected particles from said chamber through said flow channel and for delivering them to the particle outlet means.
Claim 2
Dependent Claim
204 words
A particle accumulator and test apparatus, comprising a closed chamber; means, including a plurality of input nozzles, for providing a vortex flow of a particle laden gas within the chamber; a gas ejection nozzle spaced from and centrally located at the end of the chamber adjacent the input nozzles; means, positioned between the input nozzles and the ejection nozzle, for stabilizing the flow within the chamber to permit at least one annular column of particles to accumulate within said chamber, means connected to the end of the chamber remote from input nozzles and the ejection nozzle for selectively withdrawing a collected column of particles from said chamber; said means for selectively withdrawing a collected column of particles from said chamber including means for providing a flow stabilizing rotating end wall for said chamber; means for providing a flow stabilizing rotating hub centrally located with respect to the rotating end wall; said means for selectively withdrawing a collected column of particles from said chamber including a particle outlet means; a flow channel between said rotating hub and said rotating end wall and a flow impeller for drawing collected particles from said chamber through said flow channel and for delivering them to the particle outlet means.
Claim 3
Dependent Claim
51 words
The device as recited in claim 1 including at least one annular channel adjacent the ejection nozzle for providing access to said chamber whereby treatment and test material may be inserted into said chamber and means, passing through the wall of the chamber, for providing access to the annular access channel.
Claim 4
Dependent Claim
79 words
The device as recited in claim 2 including a first shaft connected to said rotating end wall; a second shaft passing through the first shaft and connected to the rotating hub with the first shaft being at least partially supported, on bearings, on said second shaft; said first shaft being adapted to be driven through bearing friction by the second shaft and means for driving said second shaft; said flow impeller being formed as part of said first shaft.
Claim 5
Dependent Claim
23 words
The device as recited in claim 3 including a pin means for locking the first shaft and the second shaft against relative rotation.
