Abstract: A method and apparatus for stabilizing glow plasma discharges by suppressing the transition from glow-to-arc includes a perforated dielectric plate having an upper surface and a lower surface and a plurality of holes extending therethrough. The perforated dielectric plate is positioned over the cathode. Each of the holes acts as a separate active current limiting micro-channel that prevents the overall current density from increasing above the threshold for the glow-to-arc transition. This allows for a stable glow discharge to be maintained for a wide range of operating pressures (up to atmospheric pressures) and in a wide range of electric fields include DC and RF fields of varying strength.

Abstract: A re-settable fuse is provided with a movable cartridge containing a plurality of fuse elements. When a fuse is blown, a replacement fuse element may be installed into a circuit by moving, rotating or otherwise altering the position of the cartridge such that a new fuse element is inserted between electrical contacts mounted within the interior of the housing of the fuse. The bottom of the housing is configured to conform to a standardized shape of a fuse so that it may be installed into ordinary fuse box. Within the housing is a conductor which connects the fuse and the fuse element with the circuit wired into the fuse box. This conductor is exposed at the bottom of the fuse for connecting with the circuit.

Abstract: A method apparatus is provided for electrophoretically depositing particles onto an electrode, and electrohydrodynamically assembling the particles into crystalline structures. Specifically, the present method and apparatus creates a current flowing through a solution to cause identically charged electrophoretically deposited colloidal particles to attract each other over very large distances (<5 particle diameters) on the surface of electrodes to form two-dimensional colloidal crystals. The attractive force can be created with both DC and AC fields and can modulated by adjusting either the field strength or frequency of the current. Modulating this "lateral attraction" between the particles causes the reversible formation of two-dimensional fluid and crystalline colloidal states on the electrode surface. Further manipulation allows for the formation of two or three-dimensional colloidal crystals, as well as more complex "designed" structures.

Abstract: An inflatable gas pipeline stopper is used for stopping gas flow through pipelines to permit repairs to be made to gas pipelines. For plastic gas pipelines, a tapping tee is attached to the plastic gas pipeline and a gas tight apparatus having a valve is attached to the tee. Thereafter, the plastic gas pipeline can be cut with a pipe cutter that is engaged with a hexagonal head and magnetic attachment to be operated from the exterior of the air tight apparatus. The pipe cutter can be removed from the air tight apparatus and the valve of the air tight apparatus closed to prevent gas from escaping from the pipeline. The inflatable gas pipeline stopper with dual air bags can then be inserted into the plastic gas main, through the air tight apparatus and the tee, to stop the flow of gas through the pipeline. After repairs on the pipeline are complete, the inflatable gas pipeline stopper can be removed, the tee can be stopped, and the air tight apparatus can be removed.
