Patent number: 9791159Abstract: A system for storing articles can have at least two operating modes. In the first mode, gases are evacuated from the system whereby the articles are stored at a pressure less than the pressure at the exterior of the system. In the second mode, gases are evacuated while the system is open to the admittance of gases from the exterior of the system whereby the articles are ventilated by the admitted gases. The system also can have a third operating mode wherein both the first and second modes are rendered inoperative. The storage system can function so that when the articles are stored in the first mode, gases are intermittently removed from the system whereby the pressure at which the articles are stored is maintained at less than the pressure at the exterior of the system. The storage system can be located in a refrigeration appliance such as a household refrigerator.Type: GrantFiled: February 9, 2015Date of Patent: October 17, 2017Assignee: ELECTROLUX HOME PRODUCTS, INC.Inventors: Paul H. Kelly, Robert L. Cushman, Robert J Turnbull, Charles D. Baker, Aaron W. Arvia

Patent number: 5139328Abstract: An automatic hematocrit reader wherein a sample of blood in a microhematocrit capillary tube is banded with a standing wave from an ultrasonic transducer. A light source and photocell combination is used to determine the relative thicknesses of the bands of red blood cells and the bands of plasma. The hematocrit of the sample of blood is electronically calculated from this data. A calibration strip is included so that the device is calibrated each time the hematocrit is determined. The device includes a mechanical interlock/eject system for the microhematocrit capillary tube and is specifically configured so that the operator does not handle or even touch the microhematocrit capillary tube.Type: GrantFiled: March 18, 1991Date of Patent: August 18, 1992Assignee: Separation Technology, Inc.Inventors: Charles D. Baker, Owen D. Brimhall, Thomas J. McLaughlin

Patent number: 4983189Abstract: Methods and apparatus for controlling the movement of materials having different physical properties when one of the materials is a fluid. The invention does not rely on flocculation, sedimentation, centrifugation, the buoyancy of the materials, or any other gravity dependent characteristic, in order to achieve its desired results. The methods of the present invention provide that a first acoustic wave is propagated through a vessel containing the materials. A second acoustic wave, at a frequency different than the first acoustic wave, is also propagated through the vessel so that the two acoustic waves are superimposed upon each other. The superimposition of the two waves creates a beat frequency wave. The beat frequency wave comprises pressure gradients dividing regions of maximum and minimum pressure. The pressure gradients and the regions of maximum and minimum pressure move through space and time at a group velocity.Type: GrantFiled: July 25, 1988Date of Patent: January 8, 1991Assignee: Technical Research Associates, Inc.Inventors: Stephen C. Peterson, Owen D. Brimhall, Thomas J. McLaughlin, Charles D. Baker, Sam L. Sparks

Patent number: 4887458Abstract: This invention is a semiautomatic hematocrit reader apparatus and method. A microhematocrit capillary tube is positioned under a movable cursor which is then moved along the length of the microhematocrit capillary tube. A switch is depressed to make a data entry at predetermined points along the length of a blood/plasma sample in the microhematocrit capillary tube. The relative distances travelled across the packed cell volume versus the plasma is electronically calculated and displayed automatically.Type: GrantFiled: September 21, 1988Date of Patent: December 19, 1989Assignee: Separation Techology, Inc.Inventors: Charles D. Baker, Owen D. Brimhall, James E. Messinger

Patent number: 4854170Abstract: This invention is an ultrasound apparatus for determining hematocrit. A sample of blood in a microhematocrit capillary tube is acoustically coupled to an ultrasound transducer which creates a standing wave in the blood sample. Red blood cells in the blood sample are packed in bands that correspond to the nodes of the standing wave. The thickness of the bands as a function of the thickness of the remaining plasma is an indication of the hematocrit of the blood sample.Type: GrantFiled: October 12, 1988Date of Patent: August 8, 1989Assignee: Separation Technology, Inc.Inventors: Owen D. Brimhall, Stephen C. Peterson, Charles D. Baker, Merwyn D. Riddle
