Patents by Inventor Charles A. Schlutz

Charles A. Schlutz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Continuous flow fractionation and separation device and method
    Patent number: 4091989
    Abstract: A centrifuge apparatus is provided for separating red blood cells and other dense solids from a suspending liquid. An enclosure means encloses liquid suspended red blood cells and is rotatable about its axis. An injector means moves the liquid suspended blood cells into and the separated blood cells out of the enclosure means and a seal means seals the injector means to the enclosure means in a liquid-tight relationship. A plurality of red blood cells receiving means are spaced about the periphery of the enclosure means and are serially connected by ducts. Suspending liquid, passing from receiving means to receiving means, will be at least partially depleted of red blood cells after passing through each receiving means.

  • Centrifuge separation and washing device and method
    Patent number: 4076169
    Abstract: A centrifuge device and method are provided for separating and/or washing finely-divided solid particulate material suspended in a liquid. The invention is especially useful in so treating blood. The centrifuge forms a dense suspension of blood cells in a plurality of blood cells receiving means evenly spaced about the periphery of a rotatable enclosure. The receiving means have converging walls which at their juncture form a locus of maximum centrifugal force. Wash liquid is passed through the dense suspension of blood cells counter to the direction of the centrifugal force by entry into the blood cell receiving means at the locus of maximum centrifugal force. Independent conduits connect the locus of maximum centrifugal force through an injector to a supply for the wash liquid and, after fully resuspending the blood cells in a suitable resuspending liquid, the resuspended cells exit from the centrifuge via the independent conduits and injector, which have also therefore been washed by the wash liquid.
