US4046681A — Multiple matrix assembly and matrix unit for magn…

Claim 1

Independent Claim 167 words

A multiple matrix assembly for a magnetic separator comprising: a container; a plurality of magnetic matrices arranged in a longitudinal stacked array in said container; each matrix having a feed and a collection area on opposite longitudinal ends transverse to the longitudinal axis of said container and the flow through it, and having a peripheral portion surrounding it and extending longitudinally between said feed and collection areas, said matrices being disposed with their feed areas all facing in a first direction and their collection areas all facing in a second direction; inlet and outlet means in said container for feeding to and collecting from said matrices; and open receptacle means, disposed between each pair of adjacent matrices, each of said receptacle means including a transverse member proximate and coextensive with only one of said feed and collection areas, and a peripheral member extending longitudinally in one of said first and second directions from said transverse member along and sealingly engaged with said peripheral portion of said matrix.

Claim 2

Dependent Claim 167 words

A multiple matrix assembly for a magnetic separator comprising: a container; a plurality of magnetic matrices arranged in a longitudinal stacked array in said container; each matrix having a feed and a collection area on opposite longitudinal ends transverse to the longitudinal axis of said container and the flow through it, and having a peripheral portion surrounding it and extending longitudinally between said feed and collection areas, said matrices being disposed with their feed areas all facing in a first direction and their collection areas all facing in a second direction; inlet and outlet means in said container for feeding to and collecting from said matrices; and open receptacle means, disposed between each pair of adjacent matrices, each of said receptacle means including a transverse member proximate and coextensive with only one of said feed and collection areas, and a peripheral member extending longitudinally in one of said first and second directions from said transverse member along and sealingly engaged with said peripheral portion of said matrix.

Claim 3

Dependent Claim 21 words

The multiple matrix assembly of claim 1 in which said peripheral member extends in said second direction from said transverse member.

Claim 4

Dependent Claim 19 words

The multiple matrix assembly of claim 1 in which the force of gravity is exerted in said first direction.

Claim 5

Dependent Claim 69 words

The multiple matrix assembly of claim 1 in which said inlet and outlet means extend longitudinally in said stacked array of matrices and include ports in each said transverse member and a sleeve member surrounding each said port interconnected with said transverse member and extending through one or more matrices, at least one sleeve extending in said first direction and at least one sleeve extending in said second direction.

Claim 6

Dependent Claim 45 words

The multiple matrix assembly of claim 1 in which there is an additional receptacle having its transverse member disposed between the end of said container, which is at the opposite end from that toward which said peripheral members extend, and the matrix adjacent that end.

Claim 7

Dependent Claim 105 words

A multiple matrix assembly for a magnetic separator comprising: a container; a plurality of magnetic matrices each having a feed area, a collection area on opposite longitudinal ends, and a peripheral portion and being arranged in a longitudinal stacked array in said container with like areas of adjacent matrices facing each other; each of said matrices having its longitudinal ends spaced from adjacent said matrices, to form common, alternate feed and collection areas; the peripheral portion of each of said matrices being sealingly engaged with said container; and inlet means and outlet means for feeding to and collecting from said common feed and collection areas.

Claim 8

Dependent Claim 105 words

A multiple matrix assembly for a magnetic separator comprising: a container; a plurality of magnetic matrices each having a feed area, a collection area on opposite longitudinal ends, and a peripheral portion and being arranged in a longitudinal stacked array in said container with like areas of adjacent matrices facing each other; each of said matrices having its longitudinal ends spaced from adjacent said matrices, to form common, alternate feed and collection areas; the peripheral portion of each of said matrices being sealingly engaged with said container; and inlet means and outlet means for feeding to and collecting from said common feed and collection areas.

Claim 9

Dependent Claim 156 words

A matrix unit for a multiple matrix assembly for a magnetic separator in which the matrix units are arranged longitudinally in a stacked array comprising: a magnetic matrix having first and second areas on opposite longitudinal ends of said matrix transverse to the longitudinal axis of said matrix and to the longitudinal flow through it, and having a peripheral portion surrounding it and extending longitudinally between said first and second areas; and an open receptacle for housing said matrix and having a transverse member proximate to and coextensive with only one of said first and second areas and a peripheral member extending longitudinally from said transverse member along and sealingly engaged with said peripheral portion of said matrix; said transverse member including at least two ports for accommodating inlet and outlet means and a sleeve extending from said transverse member about each port through one or more matrices, at least one sleeve extending in each direction.

Claim 10

Dependent Claim 156 words

A matrix unit for a multiple matrix assembly for a magnetic separator in which the matrix units are arranged longitudinally in a stacked array comprising: a magnetic matrix having first and second areas on opposite longitudinal ends of said matrix transverse to the longitudinal axis of said matrix and to the longitudinal flow through it, and having a peripheral portion surrounding it and extending longitudinally between said first and second areas; and an open receptacle for housing said matrix and having a transverse member proximate to and coextensive with only one of said first and second areas and a peripheral member extending longitudinally from said transverse member along and sealingly engaged with said peripheral portion of said matrix; said transverse member including at least two ports for accommodating inlet and outlet means and a sleeve extending from said transverse member about each port through one or more matrices, at least one sleeve extending in each direction.
