Method and apparatus for electromagnetic powder deposition
The present invention provides a method for depositing powder particles on a substrate. The method comprises forming a planar plasma armature, accelerating the plasma armature, accelerating a column of gas with the plasma armature; and accelerating the powder particles with the column of gas. The present invention provides for a railgun, comprising first and second conducting rails, and first and second insulating rails. The insulating and conducting rails form a bore of the railgun. The first and second conducting rails are separated by the insulating rails. At least one of the rails has a port in the wall thereof, the port is adapted to introducing powder particles into the bore.Board of Regents, University of Texas Syste

Method and apparatus for switching an electrical circuit
The invention provides an explosively actuated switch and a method of using the same. The switch will include primary conductive elements which will remain generally stationary, and one or more movable conductive elements which will be clamped between the stationary elements. Various types of mechanisms may be utilized to exert a clamping force on one or more of the stationary members. An explosive material is provided to move the movable members from engagement with the stationary members upon detonation.Board of Regents, University of Texas Syste

Explosively actuated thermal opening switch
An apparatus and method are provided for controlling the switching characteristics of an explosively actuated switch. The switch comprises a conductor that is only partially severed by explosive forces. A bridge region, the conductive portion of the conductor remaining after the explosion, is then severed by thermal breakdown. Variations in the bridge region enable a user to vary the switching characteristics of the switch.Board of Regents, University of Texas Syste
