Title: Centrifuge bowl for autologous blood salvage
Inventor: BERCH STEPHEN WILLIAM
IPC: A61M1/02
Filed: 1998-07-10
Abstract: An improved centrifuge bowl and related system is disclosed which is particularly apt for enhanced autologous blood salvage applications. The centrifuge bowl assembly includes a rotatable outer bowl (20), an internal spacer (40) interconnected therewithin, and a stator assembly (60) for introducing/removing fluid during rotation of the outer bowl and internal spacer. The outer bowl and internal spacer are configured to define a lateral passageway (34) at the bottom of the assembly which terminates in an upward-facing port (80) for fluid passage therethrough into an annular, cylindrical collection region (82). The annular port may be defined by a peripheral fin (50) on the spacer and may be of a width that is less than the width of the cylindrical, annular collection region, wherein separated blood components (e.g. red blood cells) will accumulate across the width of the port during blood fill/wash cycles. As a result, enhanced washing is realized while maintaining throughput rates.

Title: Separation of air
Inventor: HINE CHRISTOPHER JOHN
IPC: F25J3/04
Filed: 1999-03-31
Abstract: Air is separated by rectification. The air is compressed in a main air compressor 2 to a first pressure. Without further compression a first flow of the compressed air is cooled in a main heat exchanger 6 to a temperature suitable for its separation by rectification. The first flow is introduced into the higher pressure column 16 of a double rectification column 14 comprising, in addition to the higher pressure column 16, a lower pressure column 18, in which a bottom oxygen fraction containing from 50 to 96 mole per cent of oxygen is formed, and a condenser-reboiler 20 placing the higher pressure column 16 in heat exchange relationship with the lower pressure rectification column 18. A second flow of the compressed air is expanded with the performance of external work in an expansion turbine 32 without further compression of the second flow upstream of the expansion. The expanded second flow is introduced into the lower pressure rectification column 18. An impure oxygen product is taken from the said bottom fraction. The external work is the generation of electrical power, and thus the turbine 32 is coupled to an electrical generator 34.

Title: A process for the simplified disposal of working fluids based on w/o invert emulsions
Inventor: FUES JOHANN-FRIEDRICH
IPC: C09K8/36
Filed: 1997-10-21
Abstract: The invention concerns a process for the facilitated waste disposal of flowable and pumpable working substances based on water-in-oil invert emulsions containing emulsifiers - in particular corresponding auxiliary agents from the field of exploratory boring of the earth, such as oil-based water-in-oil invert bore-flushing substances - and for the facilitated cleaning of solids surfaces contaminated therewith, optionally also using flowable rinsing aids. The process is characterized in that, by selecting and adapting the emulsifier/emulsifier systems to the oil phase of the invert emulsion, temperature-controlled phase inversion is ensured by solidification in the temperature range below the operating temperatures of the water-in-oil invert emulsions, but above the solidification temperature of the aqueous phase, and waste disposal or cleaning is carried out in the temperature range of the phase inversion and/or at temperatures lying therebelow. The invention further concerns the application of this process for the cleaning and waste disposal of the cuttings charged with residual amounts of boring mud from boring of the ground during and/or preferably before it is disposed of onshore or off-shore.
