  • Patent number: 6533846
    Abstract: A rotary module for implementing a high frequency pressure swing adsorption process includes a stator having a number of function compartments opening into the stator valve faces, a rotor rotatably coupled to the stator and including a number of apertures opening into the rotor valve faces, and a self-regulating clearance-type valve seal positioned between the valve faces of the stator and rotor so as to regulate the rate of gas flow between the stator and the rotor. Each valve seal includes a sealing face disposed adjacent a respective one of the rotor valve faces and is pivotable relative to the respective rotor valve face for varying the gas flow rate in accordance with the clearance distance between the sealing face and the respective rotor valve face. Each valve seal also includes a passage which communicates with one of the function compartments for varying the clearance distance in response to a pressure differential between the passage and an approaching aperture.

  • Patent number: 6406523
    Abstract: Gas separation by pressure swing adsorption (PSA) is performed within an apparatus having a plurality of adsorbers cooperating with first and second valves in a rotary PSA module, with the PSA cycle characterized by multiple intermediate pressure levels between the higher and lower pressures of the PSA cycle. Gas flows enter or exit the PSA module at the intermediate pressure levels as well as the higher and lower pressure levels, under substantially steady conditions of flow and pressure. The PSA module comprises a rotor containing laminated sheet adsorbers and rotating within a stator, with ported valve faces between the rotor and stator to control the timing of the flows entering or exiting the adsorbers in the rotor.

  • Patent number: 5975664
    Abstract: A refrigerator cabinet has a food storage compartment bounded by front facing vertical and horizontal walls. A pair of French doors are pivotally mounted to the refrigerator cabinet to close the open front of the refrigerator. In the closed position the doors have vertically extending confronting walls which include an intermediate sealing gasket extending along a major vertical portion of the confronting walls which are adapted to sealingly engage against each other to form a vertically extending seal. Upper and lower corner sealing gasket members are respectively positioned above and below the intermediate sealing gasket members and adjacent a corresponding horizontal wall of the cabinet. Each of the corner sealing gasket members has a first sealing surface adjacent the intermediate sealing gasket member to complete the vertical seal between the confronting walls of the doors when the doors are in a closed position.

  • Patent number: 5975661
    Abstract: A refrigerator has French doors with vertically extending confronting side walls. At least one of the confronting side walls has a movable sealing gasketing member adapted to sealingly engage the other confronting side wall when the doors are in a closed position. The doors move between an open position and into the closed position through a temporary intermediate partially closed position. In the partially closed position the doors extend over the refrigerator compartment with temporary non-sealing vertically extending portions of the confronting side walls of the doors spaced apart from one another a predetermined gap distance. A first set of magnets are positioned in the doors at least along the temporary non-sealing vertically extending portions of the confronting side walls.

  • Patent number: 5816080
    Abstract: A gasket assembly for use in side-by-side, or French doors for a refrigerator has door stops which bear the door closure forces by engaging the top and bottom walls of the refrigerator food compartment. The door stops form part of an edge flange of a retainer that extends along the length of the refrigerator door. The retainer acts as a seat for a flexible gasket and maintains the integrity of the flexible gasket seal alignment between the side-by-side doors. The advantage provided is that a thermal seal barrier is maintained along the entire length of the door by the door stops maintaining the gasket a constant distance from the top and bottom walls of the food compartment.

  • Patent number: 4859010
    Abstract: A refrigerator door tray assembly includes a refrigerator door with an inner liner having a cavity defined by a rear wall and two forwardly projecting supporting side walls. Each of the side walls includes an inwardly projecting shoulder having an upwardly facing ledge that slopes downwardly toward the rear wall at a predetermined angle. A tray is provided for insertion into the cavity between the side walls. The tray comprises upstanding walls each having an outwardly extending arm. The arm has a downwardly facing surface that slopes downwardly at the predetermined angle such that the downwardly facing surface of the arm is adapted to at least partially engage the ledge during insertion and lie flush on the ledge once inserted into the cavity. The tray further includes laterally extending flanges adapted to engage the ends of the supporting side walls so as to cooperate with the arms and ledges to positively locate the tray in the door cavity.
