Abstract: A filtration system interconnection structure having a filter manifold and a filter cartridge in magnetic communication with one another, such that a latching mechanism and latch blocking structure in the manifold secures the filter cartridge with a manifold sump when the filter cartridge is inserted within the manifold sump. The magnetic communication is formed between two complementary coded magnets capable of producing a magnetic shear force when in close proximity to one another. The magnetic shear force removes the latching blocking structure from interfering with the latch, allowing the latch to secure the filter cartridge. Movement of the latching blocking structure coded magnet relative to the filter cartridge coded magnet may be perpendicular or parallel with respect to each other.

Abstract: An adjustment apparatus for adjusting the angular tilt of a first component of a magnetic circuit relative to an alignment axis of a second component of the circuit uses at least one pair of spacers each of which has a thickness that changes continuously around its periphery. The spacers are arranged between the circuit components and, as a relative rotation between the spacers is changed, the combined thickness of the two spacers increases in one area, while decreasing in another. This results in a tilting of a top surface of the spacer pair relative to a bottom surface, and a corresponding change in a relative tilt of the first component relative to the second component. The spacers may be ring-shaped or disc-shaped, and allow for precise alignment of the magnetic circuit without the need for shims between the components.
