Abstract: Embodiments relate to processing a request from a user device for access rights for a resource. An access management system can send a request to query a (e.g., cached or authoritative) data store for available access rights. The query may include an exact-match or fuzzy query. A set of access-right results responsive to the query can be identified. The system may transmit a communication to the user device that identifies the set, or a subset thereof. Upon receiving a selection of a result, the system can facilitate assigning access rights corresponding to the identified result to the user. In some instances, a level of precision at which a characteristic of an access-right result is identified and/or whether or how access rights are held depends on a request load.

Abstract: Method and apparatus for feeding sand molds laterally and/o between stations of differing heights. The method and apparatus of this invention utilize walking-beam-type conveyors having spaced apart fixed outboard rails and a central reciprocating rail. Walking-beam conveyors can be disposed in perpendicular directions with a junction therebetween that allows for a perpendicular change in direction. The method and apparatus of this invention include lift, leveling, and/or lateral transfer mechanisms for lateral placement of the stations relative to the conveyance path.

Abstract: An indexing transfer station for a sand mold conveyor system, and method of conveying. The indexing transfer station rotates between two or more angled conveyors to position the sand mold for further downstream movement. The indexing transfer station includes resting pads for the sand molds, spaced apart to allow a walking transfer rail of a first conveyor to place the sand mold and, upon rotation, to allow a walking transfer rail of a second conveyor each to position under the sand mold for lifting.

Abstract: A sand molding apparatus and method, whereby cope and drag portions of a sand mold are formed simultaneously via pressurized sand delivered to each side of a pattern in a perpendicular trajectory. Two opposing sand shooting passageways include a vertical inner side wall and a horizontal inner side wall extending at an angle from the vertical inner side wall. A sand shooting plate at the outlet of each sand shooting passageway includes removable and interchangeable port and cover inserts that can be arranged in custom arrays within the sand shooting plate.

Abstract: An oil cooled cylinder liner, a method for cooling the same, and an opposed piston engine using the oil cooled cylinder liner are described. The cylinder liner includes a liner wall that has an inner face adjacent a piston bore and an outer face including an oil gallery surface. A plurality of grooves are disposed along the oil gallery surface. The grooves run parallel to each other and are spaced apart by bridging portions of the liner wall. At least some of the grooves have at least one fin disposed therein that runs parallel with the grooves. The grooves in combination with the fins increase surface area of the oil gallery to improve heat transfer from the liner wall to oil disposed along the oil gallery surface.

Abstract: A system and method for determining the quality of natural gas is provided. The system includes a fuel line for communicating natural gas to an engine. An infrared light source is disposed along the fuel line and is configured to emit a beam of infrared light into the fuel line having a wavelength of 6 to 10 micrometers. An infrared light detector detects a transmission value of the natural gas as the beam of infrared light passes through the fuel line. A natural gas quality module receives the transmission value from the infrared light detector and determines a quality value of the natural gas based on an amount of infrared light absorbed by methane in the natural gas. An engine control module, including a feed-forward control loop, receives the quality value from the natural gas quality module and alters an operating parameter of the engine in response thereto.

Abstract: A method and apparatus for moving a mold in a molding machine, such as a matchplate molding machine. A lock element, preferably but not necessarily having at least 2 pieces, is movably mounted within a platen opening of a platen and within a pallet opening of a pallet. A second piece of the lock element can be fixed or secured with respect to the pallet, for example, to fix a position of a drag flask with respect to the pallet. An indexing device can be used to handle or move at least 2 molds with respect to the molding machine.
