Abstract
Abstract Apparatus for mixing materials having no moving parts in which a plurality of elements are fitted into a conduit. The elements, which need not be permanently fastened, are self-nesting and axially overlapping. Each axially overlapping region provides a mixing matrix introducing complex velocity vectors onto the materials to be mixed. A drift space subsequent to the matrix enhances the mixing operation. The conduit and elements can be advantageously combined with a distribution head, preferably coaxial.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
Stationary material mixing apparatus, comprising a conduit having a length, a longitudinal axis through said length, and a chamber extending longitudinally through said length opening on first and second ends of said conduit and including said longitudinal axis, a plurality of abutting, self-nested elements fitted within said chamber, adjacent elements being configured as mirror images of one another, each element having lengths along the longitudinal axis where adjacent elements axially overlap defining mixing matrices inducing both counter-rotating angular velocities relative to said longitudinal axis and simultaneous inward and outward radial velocities relative to said longitudinal axis on materials moving through said mixing matrices, each element having a length along the longitudinal axis where said elements do not axially overlap, the axially non-overlapping lengths of said elements along the length of the longitudinal axis defining drift spaces for the recombination of said materials subsequent to movement through the mixing matrices.
Claim 2
Dependent Claim
149 words
Stationary material mixing apparatus, comprising a conduit having a length, a longitudinal axis through said length, and a chamber extending longitudinally through said length opening on first and second ends of said conduit and including said longitudinal axis, a plurality of abutting, self-nested elements fitted within said chamber, adjacent elements being configured as mirror images of one another, each element having lengths along the longitudinal axis where adjacent elements axially overlap defining mixing matrices inducing both counter-rotating angular velocities relative to said longitudinal axis and simultaneous inward and outward radial velocities relative to said longitudinal axis on materials moving through said mixing matrices, each element having a length along the longitudinal axis where said elements do not axially overlap, the axially non-overlapping lengths of said elements along the length of the longitudinal axis defining drift spaces for the recombination of said materials subsequent to movement through the mixing matrices.
