Abstract: Abstract of the Disclosure A system and method of separation of therapeutic components from blood.  The system includes a dual member centrifuge and a disposable single use fluid transfer set.  The set includes an elongated flexible separation chamber having an input port, a separated component output port and a residual fluid output port.  The input port and the separated component output ports are located at opposite ends of the elongated separation chamber. The centrifuge includes a receiving chamber with a selectively formed annular slot therein.  The separation chamber is positioned in the annularly shaped slot and rotated at a predetermined rotational velocity.  Fluids such as whole blood flows through the separation chamber and are separated into various therapeutic components such as platelet rich plasma and residual concentrated red blood cells.  Platelet rich plasma can be drawn off as the separated therapeutic component.  An alternate two part transfer set provides for highly efficient platelet pheresis.  The platelet rich plasma is separated from the residual red blood cells in a first part.  The platelet rich plasma flows into the second part and is separated into platelet poor plasma and platelets.  The platelet poor plasma can be drawn off and returned to a donor or collected.  The platelet concentrate can then be accumulated in a separate container.

Granted: 1991-12-31
Abstract: ABSTRACT          INTEGRATED PRESSURE EXHAUST VALVE AND FLUID COUPLING     An integrated pressure exhaust valve and pneumatic coupling is used on a truck trailer for bringing air brake pressure from a tractor to the truck trailer.  A gladhand coupling moiety is used for quick connection with an identical coupling moiety on the air pressure hose from the tractor.   A check valve mechanism is incorporated in the body of the trailer coupling moiety for permitting air flow to the brakes when pressure from the tractor is greater than pressure in the trailer brake lines, and for permitting air flow from the brake lines to the atmosphere when pressure from the tractor is decreased.   The integrated pressure exhaust valve and pneumatic coupling moiety can be mounted on the front of the trailer where it is found that pressure exhaust valve placement is most effective.

Abstract: ABSTRACT      An apparatus for controlling the illumination of a display used to present messages in a pager is described.  A microcomputer is used for controlling the operation of the display in response to a read switch being actuated.  A light switch, coupled to an illumination circuit provides display illumination upon the light switch being  manually activated.  The microcomputer also couples to the light switch to allow monitoring of the switch actuation.  Upon actuation of the light switch, when a message is being displayed, the microcomputer will maintain the illumination of the display, even after the light switch has been released.  Once the message has been-read, the microcomputer resumes monitoring the light switch, and the illumination of the display is terminated.
