Patent number: 8187867Abstract: A probe assembly includes a tubular sleeve having a passage extending between a first end and an opposing second end. The tubular sleeve is movable between an extended position wherein the first end and the opposing second end are spaced apart and a collapsed position wherein the first end and the opposing second end are moved closer together. A connector is secured to the second end of the tubular sleeve, the connector having an opening extending therethrough that communicates with the passage of the tubular sleeve, a sealing layer removably covering the opening of the connector. An elongated probe has a first end and an opposing second end, the second end of the probe being positioned within the passage of the tubular sleeve, the second end of the probe being configured to pass through the opening of the connector when the sealing layer is removed therefrom.Type: GrantFiled: January 26, 2011Date of Patent: May 29, 2012Assignees: HyClone Laboratories, Inc., Baxter International, Inc., Baxter Healthcare S.A.Inventors: Kurt T.

Patent number: 5641529Abstract: An extrusion apparatus for producing thee-dimensional objects comprises at least one die, an extruder, and a rotatable cutter plate. The die is disposed adjacent to an outlet end of the extruder. The die forms an opening defining a two-dimensional shape, and the extruder forces an extrudable material through the opening in the die. The rotatable cutter plate is disposed adjacent to the die. The cutter plate is configured to obstruct different portions of the die opening at different times as the cutter plate rotates so as to vary the shape of the extrudable material forced through the opening in the die and thereby create a three-dimensional shape. The cutter plate is configured to fully obstruct the opening in the die during each revolution of the cutter plate so as to separate the extrudable material forced through the opening in the die into individual objects.Type: GrantFiled: March 15, 1995Date of Patent: June 24, 1997Assignee: The Quaker Oats CompanyInventor: Kurt T.
