Abstract
Abstract An inline magnetic mixer for flowing fluids. A magnetic particle is contained within a flow tube through which a fluid passes. A coil made of electrically conductive material is positioned in close proximity to the flow tube and outside the flow tube. A low voltage, oscillating electrical supply energizes the coil. This sets up an oscillating magnetic field within the flow tube which causes the magnetic particle to oscillate longitudinally within the flow tube, thereby mixing the fluid stream passing through the flow tube.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
A magnetic mixing device for mixing a moving fluid stream which comprises, in combination: a block of non-magnetic material, said block including a recess formed in one face thereof and further including a passage extending completely therethrough behind said recess in close proximity thereto but not in communication with said recess, said passage defining a flow tube; an elongated magnetic stirring element contained within said passage; means for limiting the travel of said stirring element, in engagement with both ends of said passage, to prevent movement of said stirring element out of said flow tube and to allow movement of said fluid stream through said passage; a coil formed of electrically conductive material positioned in said recess in said block; and means for furnishing a low voltage oscillating electrical supply to said coil to thereby generate an oscillating magnetic field in said passage for causing said magnetic stirring element to oscillate longitudinally in said passage.
Claim 2
Dependent Claim
155 words
A magnetic mixing device for mixing a moving fluid stream which comprises, in combination: a block of non-magnetic material, said block including a recess formed in one face thereof and further including a passage extending completely therethrough behind said recess in close proximity thereto but not in communication with said recess, said passage defining a flow tube; an elongated magnetic stirring element contained within said passage; means for limiting the travel of said stirring element, in engagement with both ends of said passage, to prevent movement of said stirring element out of said flow tube and to allow movement of said fluid stream through said passage; a coil formed of electrically conductive material positioned in said recess in said block; and means for furnishing a low voltage oscillating electrical supply to said coil to thereby generate an oscillating magnetic field in said passage for causing said magnetic stirring element to oscillate longitudinally in said passage.
Claim 3
Dependent Claim
142 words
A magnetic mixing device for mixing a moving fluid stream which comprises, in combination: a generally spool-shaped block, formed of a nonmagnetic material, having two separated end members connected by a hub member, said spool-shaped block including a passage extending completely through one of said end members to define a flow tube; a coil formed of a plurality of turns of a conductive wire wound around said hub member; an elongated magnetic stirring element contained within said passage; means for limiting the travel of said stirring element, in engagement with both ends of said passage, to prevent movement of said stirring element out of said flow tube; and means for furnishing a low voltage oscillating electrical supply to said coil to thereby generate an oscillating magnetic field in said passage for causing said magnetic stirring element to oscillate longitudinally in said passage.
