  • Publication number: 20140284266
    Abstract: A filter element includes a substantially cylindrical center tube having a first end, a second end opposite the first end, and a central longitudinal axis. The filter element also includes filter media extending circumferentially around and longitudinally along the center tube, and a plate connected to the center tube proximate the first end. The plate includes an orifice and a cap. The orifice includes a pilot feature configured to locate the filter element at a single circumferential position relative to the longitudinal axis, the cap extending from a top surface of the plate toward the second end and having an inner wall configured to mate with a drain plug. In such embodiments, the orifice and the cap are disposed radially inward of an inner circumference of the center tube, and at least one of the orifice and the cap extends circumferentially around an additional longitudinal axis spaced radially from the central longitudinal axis of the center tube.

  • Patent number: 8157997
    Abstract: A canister filter system includes a base, a canister attachable to the base, and positioned inside the canister a filter element having filter media. A drain engages and forms a seal with the filter element in a closed position. In an open position, the drain allows fluid to be removed from the canister. Because the drain is engaged to and forms a seal with the filter element in the closed position, the drain cannot be closed unless a filter element is present inside the canister. This prevents accidental or intentional use of the filter system without a filter element in place.

  • Patent number: 5702660
    Abstract: A process is provided for injection molding a plastic material into an interfacial space between a spherical ball and a spherical cavity of a ball and socket joint assembly to form a plastic bearing which has an as-molded tapered undercut. A sacrificial ring having a preselected outer diameter and a generally triangular cross-sectional shape is selected. The sacrificial ring is placed around the ball adjacent the neck of the ball assembly. The sacrificial ring is rigidly confined between the ball, the cavity, and the mold. The plastic material is injection molded into the interfacial space and a plastic bearing having a tapered undercut which mimics the shape of the sacrificial ring is formed.

  • Patent number: 5599874
    Abstract: A thermoplastic polyurethane elastomeric seal composition comprising, by weight, about 90% to 99% thermoplastic polyurethane elastomer and about 1% to 10% fibers. Also, the thermoplastic polyurethane elastomer is derived from the reactants comprising: (i) a mixture of polyol and an aromatic chain extender in a molar ratio in the range of from about 40:60 to about 60:40 of butanediol glycol adipate to hydroquinone bis 2-hydroxyethyl ether, and (ii) 1,5 naphthalene diisocyanate present in a molar ratio in the range of about 50:50 to about 54.5:45.5 of 1,5 naphthalene diisocyanate to the said first mixture of polyol and an aromatic chain extender. After curing, the thermoplastic polyurethane elastomeric seal compound has outstanding wear resistance and low compression set.This thermoplastic polyurethane elastomeric seal compound is particularly useful in making shaft seals subject to high wear and high pressure, for use in hydraulic rams in earthmoving equipment.
