Abstract: An electrogasdynamic tube is coupled in parallel with a switch for interrupting high voltage direct current. In course of opening the switch, a flow of ionized fluid in the tube conducts current to prevent arcing across the switch contact or to suppress an arc if it develops.

Abstract: An improved electrostatic precipitator device capable of significant size reduction having flat parallel plates consisting of an ionizing corona discharge portion as a unitary structure which is utilized to effectuate precipitation of entrained particles from an air stream onto the surface of a plurality of associated collection members, as an air stream containing entrained particles is cleaned in passing through the precipitator device. The ionizer discharge portion of the unitary structure comprises a plurality of substantially uniformly spaced apart sharp electrical conductive protrusions directed to alternate sides of the unitary structure; thereby forming a uniform ionization region with a parallel portion of the collector extending the full length of the ionizer. The remainder of each of the unitary structure functions as a passive electrode which cooperates with the remaining portion of the collector to form highly concentrated electrostatic fields therebetween for enhanced collection efficiency with minimum re-entrainment of the particles to be collected.

Abstract: An electrogasdynamic converter operating on a gaseous stream of the type including a flow channel having ionizing electrode means in an upstream portion to produce charges in the stream, and collector electrode means spaced downstream from the ionizing electrode means to neutralize the charges carried in the downstream direction by the flow. The converter is operated to establish in the intermediate section of the flow channel between the ionizing electrode means and the collector electrode a high resistance path at the boundary of the flow path for charges carried in the stream. The high resistance may be formed by a thin liquid or solid film at the flow path boundary, or by spaced conductive elements extending through a dielectric channel to be flush with the flow boundary and exposed to the stream. In the latter event, a thin resistive film may be deposited on the outside of the channel to have successive sections thereof connected between the conductive elements. A third alternative utilizes a flow channel constructed of a highly resistive conducting material.

Abstract: A METHOD AND MEANS FOR REPRODUCING AN IMAGE ON A DIELECTRIC SHEET, OR IRREGULAR OR CURVED SURFACE, COMPRISING THE USE OF AN ELECTROGASDYNAMICALLY PRODUCED SPACE CHARGE CLOUD OF IONIZED INK TO DEVELOP AN IMAGE OF A LIGHT PATTERN PROJECTED ONTO A CONVENTIONAL XEROGRAPHIC PLATE. THE DEVELOPED INK IMAGE IS OF IMPROVED QUALITY BY VIRTUE OF THE TENDENCY OF ELECTROGASDYNAMICALLY PRODUCED PARTICLES TO ACHIEVE A UNIFORM CHARGE DISTRIBUTION ON A DIELECTRIC SURFACE.

Abstract: An apparatus and method for printing an image of a pattern of sound waves on a dielectric sheet, such as paper or the like, comprising the use of a space charge cloud of ionized ink from an electrogasdynamic generator to develop an electrostatic charge image of the sound pattern which has been formed on the dielectric sheet using an acoustic image converter plate. By virtue of the high charge on the ink, a high quality image is developed on the sheet even though the sound wave patterns resulting from ultrasonic scanning of a test object or from the energizing of an acoustical transducer may be comparatively weak.
