Title: Propulsion mechanism for endoscopic systems
Inventor: ZIEGLER TROY J
IPC: A61B1/04
Filed: 2004-04-14
Granted: 2011-05-24
Abstract: A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and U motorized or powerable frame The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid.The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment.  The motion of the toroid can be powered or unpowered and the direction and speed may be controlled. The apparatus may be used to transport a variety of accessory devices to desired locations within tubular spaces and environments where medical and non-medical procedures may be performed.

Abstract: A dual function heating and toasting apparatus is provided for radiantly heating or surface toasting bread-type food products. The apparatus includes a housing defining a heating/toasting chamber. A generally vertically oriented, center fixed heating platen is disposed in the chamber. A pair of generally vertically oriented, movable heating platens are disposed on opposite sides of the center fixed platen. A gate is movably mounted on the housing near the bottoms of the platens for movement between a closed position to hold a product between the platens and an open position allowing a finished product to exit the chamber. A product such as a bagel can be placed into the chamber onto the gate between one of the movable platens and the fixed platen and spaced therefrom to heat the bagel by radiant heat. Alternatively, a product such as a bun can be placed in the chamber onto the gate and the movable platen moved to bias the bun against the fixed platen to surface toast the bun. The gate is movable to the open position to allow the heated bagel or the toasted bun to exit the chamber.

Title: Systems and methods for cleaning a batch of granular material
Inventor: MAUNDER ANDREW
IPC: B07B9/00
Filed: 2003-07-21
Granted: 2011-07-05
Abstract: An apparatus and method cleans a batch of pellets or granules prior to use in an extrusion process. Loose contaminants having material characteristics that are undesired for the extruded product are first removed from the batch using a deduster. The deduster may also remove uncontaminated fines and fluff from the batch. Pellets that are defective or otherwise undesired for the extrusion process as well as other loose particle contaminants can then be efficiently detected and removed without the risks of fines clogging the apparatus or shielding the detection process. Magnets may help remove particulates of ferrous material before or after the removal of defective pellets. The resulting batch of pellets helps to produce extruded materials of higher quality, such as insulation material in electrical cables.

Title: System and method for takeover of partner resources in conjunction with coredump
Inventor: COATNEY SUSAN M
IPC: G06F11/20
Filed: 2005-01-25
Granted: 2011-07-12
Abstract: A system and method for allowing more rapid takeover of a failed filer by a clustered takeover partner filer in the presence of a coredump procedure (e.g.  a transfer of the failed filer's working memory) is provided. To save time, the coredump is allowed to occur contemporaneously with the takeover of the failed filer~s regular, active file service disks by the partner so that the takeover need not await completion of the coredump to begin. This is accomplished, briefly stated, by the following techniques. The coredump is written to a single disk that is not involved in regular file service, so that takeover of regular file services can proceed without interference from coredump. A reliable means for both filers in a cluster to identify the coredump disk is provided, which removes takeover dependence upon unreliable communications mechanisms.
