Abstract
Official abstract text for this publication.
An apparatus suitable for separating particles and methods for using such apparatus are provided.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for separating particles, wherein particles traveling through the apparatus are separated into two or more groups based on one or more of the following: inertial characteristic differences and aerodynamic characteristic differences between the particles such that at least one of the two or more groups of particles exits an interior void volume portion of the apparatus wherein the entirety of the particles that exit the interior void volume portion of the apparatus, are treated and the entirety of the treated particles are reintroduced into the same interior void volume portion of the apparatus at the apparatus' particle inlet as the particles travel through the apparatus, wherein the apparatus is void of a macerator such that the particles do not contact a macerator. 2. The apparatus according to claim 1 wherein the particles are selected from the group consisting of: fibers, granular substances, powders and mixtures thereof. 3. The apparatus according to claim 1 wherein the particles comprise fibers. 4. The apparatus according to claim 3 wherein the fibers comprise pulp fibers. 5. The apparatus according to claim 3 wherein the fibers are selected from the group consisting of: staple fibers, synthetic fibers, absorbent gel materials, bicomponent fibers and mixtures thereof. 6. An apparatus for separating particles, wherein particles traveling through the apparatus are separated into two or more groups based on one or more of the following: inertial characteristic differences and aerodynamic characteristic differences between the particles such that at least one of the two or more groups of particles exits an interior void volume portion of the apparatus wherein the entirety of the particles that exit the interior void volume portion of the apparatus, are treated and the entirety of the treated particles are reintroduced into the same interior void volume portion of the apparatus at a point in the apparatus' interior void volume prior to the apparatus' particle outlet as the particles travel through the apparatus, wherein the apparatus is void of a macerator such that the particles do not contact a macerator. 7. The apparatus according to claim 6 wherein the particles are selected from the group consisting of: fibers, granular substances, powders and mixtures thereof. 8. The apparatus according to claim 6 wherein the particles comprise fibers. 9. The apparatus according to claim 8 wherein the fibers comprise pulp fibers. 10. The apparatus according to claim 8 wherein the fibers are selected from the group consisting of: staple fibers, synthetic fibers, absorbent gel materials, bicomponent fibers and mixtures thereof.
