Abstract: DISPOSABLE CENTRIFUGAL BLOOD PROCESSING SYSTEM                      Herbert M. Cullis Abstract of the Disclosure A continuous flow centrifugal processing system for separating whole blood into fractional components in-cludes a centrifugal separator unit having a molded bowl-shaped outer shell dimensioned to fit within a rotatably-driven casing on an associated centrifuge apparatus.  A bowl-shaped inner shell disposed within the outer shell forms therewith a-thin separation channel radially spaced from the axis of ro-tation wherein fractions are separated from the whole blood under the influence of centrifugal force.  A rotating seal carried on the processing chamber between ports in the chamber and the non-rotating portions of the system.  The outer shell includes a relatively thin side wall portion which is inwardly biased toward a side wall portion on the inner shell when seated in the casing.  A plurality of projections on the side walls limit inward deformation of the outer shell to maintain a very close concentric spacing between the shell members to facilitate rapid separation of blood flowing through the chamber.          By reason of the shell members being molded, the processing chamber can be economically produced in large quantities for disposable one-time use.

Abstract: Abstract of the Disclosure Digital sootblower control systems and methods therefor are provided in accordance with the teachings of the present invention. In the digital sootblower control systems provided within the present invention, a programmable controller is interconnected to a scanner, a display panel, sootblower drivers, sootblower signal receivers, and information input panels. The information input panels are capable of designating sootblowers within the system, sootblowing program routines to be established and sequences of program routines to be initiated. The programmable controller is provided with an executive program which is determinative of system parameters to be monitored as well as limits upon soot-blowing program routines to be established. Once a sootblowing program routine has been initiated by an operator, the programmable controller issues orders to the sootblower drivers to start an initial sequence of sootblowers defined in the initiated sootblowing program routine. Thereafter, the scanner cyclically addresses all sootblowers so that the inactive or active state thereof is supplied by the sootblower signal receiver to the display panel which provides indicia as to the state of the system and to the programmable controller for monitoring purposes. Should problems develop with sootblowers in service being monitored by the controller, the problem area and malfunctioning sootblower are indicated at the display and when appropriate, the unit -i-is returned to an inactive state. If the controller malfunctions, sootblower operation may be manually initiated by an operator from the information input panel despite the malfunctioning of the programmable controller.                             -ii-

Abstract: Abstract of the Disclosure A method and apparatus for transmission of ultrasound to and reception of ultrasound from a fluid from outside its container.  An ultrasonic transducer generates sound waves longitudinally in a trans-mission bar that has a reflecting surface at such an angle with the ultrasonic path that the longitudinal waves are internally reflected as shear waves in the direction of an interface between the transmission bar and the fluid.  The impinging of the shear-mode waves on the interface results in an efficient transmission of energy into the fluid and an effi-cient reception of echo signals from the fluid.  Since longitudinal waves are coupled from the transducer to the metal, a rigid bond between trans-ducer and metal is unnecessary.  The coupling may be achieved by means of a liquid-filled interface that does not subject the delicate transducer to damage from stresses produced by differential thermal expansions.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a process of producing vinyl polymers by an inversion polymerization technique in the presence of a coating on the internal surfaces of the polymerization reactor. By inversion polymerization is meant conducting the initial stage of the polymerization reaction wherein the monomer or monomers being polymerized constitute the continuous phase and in the latter stage of polymerization, water constitutes the continuous phase.  The coating is comprised of a water-soluble suspending agent, such as an alkyl or alkyl hydroxyalkyl cellulose ether.  By means of the present inventive process, polymer buildup on the internal surfaces of the reactor are reduced.
