Patent number: 9393517Abstract: An air compression system and method for an air separation plant in which air is compressed in a series of compression stages and a temperature swing adsorption unit adsorbs water vapor and carbon dioxide. The temperature swing adsorption unit is situated at a location of the compression stages such that air pressure upon entry into the adsorbent beds is between about 400 psia and about 600 psia. Each of the adsorbent beds of the unit have a minimum transverse cross-sectional flow area that will set the air velocity of the air to a level below that at which adsorbent bed fluidization would occur. Such operation allows fabrication costs of the adsorbent beds to be reduced because less adsorbent and smaller adsorbent beds are required while power consumption will be at a minimum.Type: GrantFiled: April 23, 2013Date of Patent: July 19, 2016Assignee: PRAXAIR TECHNOLOGY, INC.Inventors: Mohamed Hashi, Michael C. Johnson, John Royal

Publication number: 20090196526Abstract: A scanning device for biological slides is provided, which can be operated in an interactive routine mode as well as in an unsupervised high speed automatic mode. In the first case, typical components, which the pathologist is used to operating manually, such as the microscope, the stage and the focus, and which have to be motorized for the automatic unsupervised system mode, are configured to simulate manual use, operation, and response. A non-interlaced area scan camera supports the interactive selection and acquisition of individual images in the manual mode, as well as the continuous high-speed scan motion for the rare event detection and virtual slide scan applications of the system. Due to the particular requirements to accommodate both operational modes, methods are described for constructing the virtual slide out of image tiles with varying overlap areas in the x- and y-directions.Type: ApplicationFiled: March 31, 2009Publication date: August 6, 2009Inventors: Joachim Helmut Schmid, Thomas Gahm, Kevin Russell Kooy, Rainer Dorrer, Bruno Krief, John Royal Cheeseman
