  • Patent number: 6730217
    Abstract: A tank [A] has a fluid inlet, a fluid outlet, and a closure [B] wherein the tank may be positioned in line as a pressure vessel. A magnetic core assembly includes elongated permanent magnets [C] and magnet covers or tubes [D] constructed of non-magnetic material for collecting magnetic particles from a liquid. The core assembly is carried in the tank and is removable after the separate closure is removed from the tank. The method contemplates separating the magnets from the tubes for removal of the magnetic particles from the magnetic core assembly externally of the tank and independently of the closure.

  • Patent number: 6355176
    Abstract: An assembly and method for collecting and releasing magnetic materials includes an elongated permanent magnet (A) within an elongated cover (B) constructed from non-magnetic material for providing a collection area for the magnetic materials thereon opposite the magnet. Apparatus (C) separates the magnet to a more remote position in relation to the collection area for releasing magnetic materials from the elongated cover. The magnet and the cover may be moved while in superposed closely adjacent relation for collecting magnetic material and thereafter separated for releasing magnetic material collected on the cover. A driven conveyor (D) may be included Ln the assembly for transporting the magnet and the cover through a coolant liquid containing magnetic materials in the form of particulate matter formed during a machining operation.

  • Patent number: 5819949
    Abstract: A closure operator member (E) is urged by a fastening member (F) extending across opposed brackets (D) into sealing relation across an opening in an end member (C) extending about a tubular housing (B) for receiving a bar magnet (A). A camming action or wedging is achieved thereby exerting a compressive force against a deformable sealing member. A mounting apparatus includes opposed transversely spaced longitudinal brackets (H) which are pivotally adjustable at (I) for providing support locations for elongated bar magnets (A).
