  • Patent number: 9393517
    Abstract: 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.

  • Patent number: 7722046
    Abstract: A game apparatus having a roulette wheel with a plurality of wheel sections, a pointer for randomly selecting one of the wheel sections, and a playing surface adapted for placing wagers concerning the randomly selected wheel section. Each of the wheel sections has two separate number representations, such as the faces of a pair of dice, which are summed to represent a summation for the wheel section. The playing surface has a plurality of wager sections corresponding to the summations of the wheel sections on the roulette wheel. The roulette wheel can further include a second plurality of wheel sections having representations of the suits of a deck of playing cards thereon and the playing surface can further include one or more wager sections corresponding to the second plurality of wheel sections.

  • Publication number: 20090196526
    Abstract: 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.

  • Publication number: 20070033952
    Abstract: A method of storing biological samples in which the biological samples are stored in a stack within a vessel interior of an insulated vessel. A pool of liquid cryogen is maintained within the vessel interior by condensing cryogenic vapor boiled off of the pool of liquid cryogen with a cryocooler having a cold finger. The cryocooler and cold finger are positioned so that a cold heat exchanger of the cold finger is in thermal contact with the cryogenic vapor and is positioned above the stack, so as to also maintain a temperature difference within the insulated vessel, between a bottom region of the stack and a top region of the stack, of no greater than about 65K.
