Publication number: 20240123132Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.Type: ApplicationFiled: December 22, 2023Publication date: April 18, 2024Applicant: DEKA Products Limited PartnershipInventors: Kevin L. Grant, Michael J. Wilt, Brian D. Tracey, Brett A. Rudolf, David E. Collins, Lisa A. Gustin, James D. Dale, Jesse T. Bodwell

Patent number: 11939566Abstract: A system and method for growing and maintaining biological material including producing a protein associated with the tissue, selecting cells associated with the tissue, expanding the cells, creating at least one tissue bio-ink including the expanded cells, printing the at least one tissue bio-ink in at least one tissue growth medium mixture, growing the tissue from the printed at least one tissue bio-ink, and maintaining viability of the tissue.Type: GrantFiled: September 2, 2021Date of Patent: March 26, 2024Assignee: DEKA Products Limited PartnershipInventors: Christopher C. Langenfeld, David D. B. Cannan, Dirk A. van der Merwe, Dean Kamen, Jason A. Demers, Frederick Morgan, Timothy D. Moreau, Brian D. Tracey, Matthew Ware, Richard J. Lanigan, Michael A. Baker, David Blumberg, Jr., Richard E. Gautney, Derek G. Kane, Dane Fawkes, Thomas J. Bollenbach, Michael C. Tilley, Stuart A. Jacobson, John F. Mannisto

Patent number: 8516968Abstract: A fluidized bed is described and which includes a multiplicity of fluidizing manifolds positioned in spaced relation one relative to the others; an enclosure positioned in gravity receiving relation relative to the multiplicity of fluidizing manifolds and which has an intake and a discharge end, and wherein particulate matter received in the fluidized bed moves under the influence of gravity from the intake end to the discharge end, and a moveable gate is mounted on the second discharge end of the enclosure and which is operable to selectively occlude a discharge aperture and which further facilitates the selective removal of particulate matter and waste material entrained with same, and which moves under the influence of gravity to the discharge end thereof.Type: GrantFiled: March 29, 2010Date of Patent: August 27, 2013Assignee: Outotec OyjInventors: LeRoy B. Pope, Michael L. Murphy, James M. Scranton, James R. Thomas, Peter Mohr, Ben H. Cosby, Michael E. Tracey, Mark R. Castle, Douglas W. Scrafford, Greg Dahlstrom

Patent number: 6071571Abstract: A two-step method to porcelain-coat an article is provided particularly useful for porcelain-coating a gas burner used in a gas-fired residential barbecue grill. A gas burner constructed from mild enameling-grade steel is dipped in a slip containing porcelain frit and manipulated so that the slip adequately coats and adheres to the interior surfaces of the burner. The porcelain-containing slip simultaneously coats and adheres to the peripheral "shoulders" and particularly to the interior "shoulders", of the gas jet openings of the burner. A second coating of porcelain-containing powder is then applied, for example, electrostatically or by other conventional powder application techniques, to the exterior surfaces of the burner. The properties of the porcelain-containing powder of the second coating are adjusted for optimal coating properties. Then, the double coated gas burner is fired in a continuous furnace at a peak firing temperature of 1480.degree. F. to 1550.degree. F., with a target of 1530.degree. F..Type: GrantFiled: February 26, 1998Date of Patent: June 6, 2000Assignee: Porcelain Metals Corporation, Inc.Inventors: Allan C. Lerch, Michael E. Tracey

A second coating of porcelain-containing slip is then applied, for example, by spraying or other conventional wet application techniques, to the exterior surfaces of the burner. The properties, for example specific gravity, of the porcelain-containing slip of the second wet coating are adjusted for optimal coating properties. Then, the double slip-coated gas burner is fired in a continuous furnace at a peak firing temperature of 1480.degree. F. to 1550.degree.
