  • Patent number: 9903351
    Abstract: A device for transfer of granular solid material between two chambers at different pressures. A piston type transfer pump device used in a horizontal position transfers granular material into the compression chamber by gravity and evacuates the material into the exhaust chamber at a higher pressure. Such a device may for example find an application for feeding a gasification reactor with biomass.
    Type: Grant

  • Patent number: 4015121
    Abstract: This invention relates to an apparatus and a method for determining the concentration of a first reactant in a medium. A disc is saturated with a solution containing the first reactant and immersed into a second reactant fluid. A chemical reaction occurs between the first and second reactants to produce a gas which is trapped by the disc. The disc is buoyed to the surface of the second reactant fluid by the gas produced. The process is electronically timed using photocells to start and stop an electronic clock and a digital display displays the time elapsed in tenths of seconds.
