Abstract: A magnetic device for attachment on an exterior wall of a canister where the canister is mounted within a liquid flow path. The purpose of the device is to attract ferrous particulate matter flowing within the flow path and cause that ferrous particulate matter to be fixed to the inside surface of the canister therefore no longer flowing in the flow path. The device has a frame which includes a cavity and within that cavity is mounted a baseplate. Mounted on the baseplate are a pair of blocks. Mounted on each of the blocks is a plurality of magnets with the magnets mounted in a side abutting relationship in conjunction with each block. Between the blocks is located a bridge. The bridge permits limited flexing of the frame so the frame can be used to accommodate to different diameters of canisters within about a one-half inch range.

Abstract: A rotary damper includes a housing and a vane. There is an indentation in the housing which permits fluid to flow readily from one side of the vane to the other during part of the rotary stroke. At the end of the rotary stroke, there is an alternative path for fluid to take from one side of the vane to the other, and this path preferably includes an adjustable aperture so the amount of damping at the end of the stroke can be adjusted.

Abstract: A molded piston includes a base plate, having a plurality of holes, and a polymeric material molded around the base plate and extending through the holes so as to form a mechanical bond between the base plate and the polymeric material. The molded piston preferably includes integral seals in its outer circumferential surface and integral standoffs on its end surfaces. In some preferred embodiments, the molded piston also includes a magnet which creates a magnetic field in the area of the piston.
