  • Patent number: 5373197
    Abstract: A microprocessor-controlled power supply with substantially independent high voltage outputs monitors and regulates two separate electrophoresis applications running simultaneously. The software associated with the dual output power supply provides independent control of each application, including automatic crossover between control parameters within each application. After parameter values are selected for each application and the applications are initiated, the software monitors the actual parameter values with relation to the selected values and adjusts the actual value of the controlling parameter for each initiated application to maintain the actual parameter values within the selected parameter values.

  • Patent number: 4454028
    Abstract: An article or can sorting apparatus for separating articles having a recycle value from articles having no recycle value is defined by an annular article supporting surface positioned at about 45 degrees to horizontal, a cylindrical wall positioned in relation to the surface to define an article processing chamber, a feed hopper into which a plurality of the articles are deposited for feeding into the chamber, and an article conveying disc or wheel positioned in parallel relation to the surface and having a plurality of outwardly extending article pusher arms for separating the articles, such as discarded beverage cans, from the plurality of articles and conveying the articles one at a time about the annular surface to a material discriminator and a weight scale and toward an accept door or a reject door. The material discriminator or metal detector, the scale, and the accept and reject doors form segments of the article conveying surface.
