Abstract: Plasmapheresis by filtration can be carried out with high efficiency for long periods by conducting blood over a surface of a membrane and passing plasma at an accelerating rate until the threshold level is attained, maintaining the rate of passing plasma until the ceiling system transmembrane pressure difference is attained and then reducing the passing of plasma and the system transmembrane pressure difference and allowing the membrane to clear before repeating the cycle.

Abstract: Adhesive pouch connecting rings with radially extending gripping portions are formed and stacked in angularly offset relation on a plurality of ostomy faceplates in a highly automated fashion. Sets of rings are die cut from a continuous adhesive coated sheet. Each set includes a plurality of spaced, identically oriented rings, in an arcuate pattern across the sheet. The sheet is intermittently advanced to bring the sets, one at a time, into alignment with faceplates located on a round platform. The platform is indexed to move the faceplates stepwise through a path coincident with the pattern of the ring sets. Each time the platform is indexed, a set of rings is removed from the sheet and the rings are placed on the respective faceplates, each in proper angular relation with the previous rings. Faceplates with a full complement of rings are removed from the platform.

Abstract: A system and method is disclosed for the rapid detection and (or) purification of analytes in a sample. The system makes use of a fluid receptacle containing a capture reagent and a manifold having two ports. A sample containing an analyte disposed within the fluid receptacle is subjected to a capture reagent and processed by inserting the open end of the receptacle in one port. Vacuum, gas, reagents, and wash fluids are then applied to the second port to effect rapid interaction between the capture reagent and analyte, efficient washing of the capture reagent and detection and/or collection of the analyte.The system and method provide a rapid safe, uncomplicated means of automating processes based on affinity complexation principles. Encompassed within this category of processes are immunoassays, nucleic acid hybridization tests and affinity separations.

Abstract: Amorphous copolymer of perfluoro-2,2-dimethyl-1,3-dioxide with at least one fluoro comonomer selected from one or more of ten defined classes having a recited minimum mole proportion of perfluoro-2,2-dimethyl-1,3-dioxole, in no event less than 65%, have high glass transition temperatures of 140.degree.

Abstract: A centrifuge rotor is characterized by a pair of magnetically attractive segments which are located between a clamping knob on an axially extending mounting bolt and the body of the rotor. The bolt holds the rotor to a drive spindle with a predetermined clamping force. As the rotor is rotated past a predetermined rotational speed the attractive force between the segments is overcome to cause the segments to displace apart thereby diminishing the magnitude of the clamping force holding the rotor in its connection to the drive spindle.
