  • Patent number: 11322814
    Abstract: A device for preventing a signal induced by hazardous EMI on a power line in a group of multiple adjacent, parallel power lines of the same phase in an electrical power system from reaching an electrical component connected to one of the multiple power lines, the device comprising at least one conductive impedance transition element having a disk-shaped structure with multiple holes for receiving the multiple adjacent power lines of the same phase, the disk-shaped structures each having an outer diameter that is greater than diameter of all of the multiple parallel power lines to deliberately create an impedance mismatch between the conductive impedance transition elements and adjacent portions of the multiple power lines. The impedance mismatch causes the conductive impedance transition elements to reflect high-frequency components of a signal induced on the multiple power lines by hazardous EMI and the high-frequency components are reflected and dissipated as heat.

  • Patent number: 11114856
    Abstract: The present disclosure provides a method of protecting a component using a deliberately created impedance mismatch between conductive impedance transition elements and an electric power line. The method comprises coupling a plurality of conductive impedance transition elements having a greater diameter than the power line at a position between an extended length of the power line and the component. The difference between the diameters of the conductive transition elements and the power line causes an intentional impedance mismatch between the two or more impedance transition elements with adjacent portions of the power line, and the mismatch causes high-frequency components of the transient electromagnetic signals induced on the power line by the transient electrical disturbance to be reflected by at least one of two or more impedance transition elements away from the protected component.

  • Patent number: 10181376
    Abstract: An Electron-coupled transformer for generating a high voltage output pulse as an amplified version of an input pulse includes a cylindrical triode electron tube with a central anode along main axis and a grid and cathode radially spaced from the anode. The anode has a first end directly grounded and a second end insulated from a direction connection to ground. The cathode and the grid form a traveling wave electron gun that produces, when the grid is grounded through a phase matching network, a radially symmetrical collapsing traveling wave of ground potential in the Transverse Electromagnetic mode. The foregoing wave of ground potential causes a beam of electrons to flow from the cathode to the anode and causes a voltage output pulse to be produced on the second end of the anode, whose magnitude is an amplified version of the input pulse that is injected into the cathode.

  • Patent number: 9406478
    Abstract: A method for inducing chemical reactions using X-ray radiation comprises generating an irradiation volume within the interior of a reaction vessel by introducing X-ray radiation into the volume, in which two or more reactants are introduced. With respect to the two or more reactants and any subsequently created intermediate reactant or reactants, the aggregate extent to which the foregoing reactants are to be ionized to any degree is selectively controlled, and the average degree of ionization in the irradiation volume, from partial to total, of that portion of the foregoing reactants which is to be ionized is selectively controlled, through control of the fluence and energy of the X-ray radiation, to thereby induce selective reactions of reactants to occur in the irradiation volume. One or more reactants may be delivered through a double-walled pipe containing X-ray shielding to prevent their premature irradiation before being injected into the irradiation volume.
