  • Publication number: 20020034458
    Abstract: A process of producing hydrogen by autothermal steam reformation of a hydrocarbon comprises the steps of providing a reactor vessel having a fluidized catalyst bed, introducing steam and a gaseous hydrocarbon, introducing oxygen, maintaining the bed temperature below the spontaneous combustion temperature of the hydrocarbon in a fluidized bed, and withdrawing hydrogen by means of a perm selective membrane. An apparatus for producing hydrogen comprises a reactor vessel, steam and hydrocarbon inlets, an oxygen inlet, a fluidized bed of catalyst within the reactor vessel and a perm selective membrane for withdrawing hydrogen from the reactor.
    Type: Application

  • Patent number: 6188470
    Abstract: A Bioenergetic Data Collection Apparatus utilizing a modified oximeter (1) to collect signals characteristic of blood flow in terminal tissue, such as a finger tip (12). A processing means (7) in signal connection with the modified oximeter (1) receives and analyzes the signals to produce pulse waveforms, or a pulse waveform sequence, that is displayed on a high resolution video display (5). An isolation means (8) is provided between the modified oximeter (1) and the processing means (7) to ensure no lethal voltages can threaten a patient. A variety of aids are provided to assist an appropriately skilled practitioner to make a prognosis from the displayed data. The tools include measurement of the ratio of heart activity to heart rest, variation in systolic pulse amplitude, variation in pulse shape, etc.

  • Patent number: 6098665
    Abstract: A method for lining a conduit with a deformable plastics liner pipe, the claimed method including deforming the liner along its length to a cross-section with reduced external dimensions relative To the dimensions of the undeformed liner and binding the liner by helically winding an elongate flexible element around the liner along its length to maintain it in the deformed cross-section. The method further includes drawing the bound liner into the conduit to be lined and releasing the binding to allow the liner to assume a cross-section substantially corresponding with the internal cross-section of the conduit. The elongate flexible element is supplied to the liner from a bobbin or the like through which the liner is passed in the deformed cross-section, the bobbin or the like being mounted for rotation around the liner as it passes therethrough to wind the elongate flexible element around the liner.
