Claim 1
Independent Claim
172 words
AN APPARATUS FOR REACTING A GASEOU SUBSTANCE COMPRISING: (A) A NOZZLE HAVING AN INWARDLY TAPERING INLET PORTION, AN OUTWARDLY FLARING OUTLET PORTION, AND A THROAT PORTION CONNECTING SAID INLET AND OUTLET PORTIONS; (B) MEANS FOR ADMITTING A GASEOUS SUBSTANCE TO SAID INLET PORTION, AT A PRESSURE SUFFICIENT TO CAUSE SAID SUBSTANCE TO BE DISCHARGED FROM SAID OUTLET PORTION AT SUPERSONIC SPEED; (C) A COLLECTOR TUBE HAVING AN AXIS AND BEING AXIALLY ALIGNED WITH OUTLET PORTION, SAID TUBE AND SAID NOZZLE JOINTLY CONSTITUTING AN AXIAL CONDUIT FOR THE FLOW OF SAID SUBSTANCE, SAID COLLECTOR TUBE HAVING AN AXIALLY INWARDLY TAPERING ENTRANCE PORTION, AN OUTWARDLY FLARING DISCHARGE PORTION, AND A CENTRAL PORTION CONNECTING SAID ENTRANCE AND DISCHARGE PORTIONS, SAID OUTLET PORTION AND SAID ENTRANCE PORTION DEFINING THEREBETWEEN AN OPENING TRANSVERSE OF SAID AXIS; (D) A SUBSTANTIALLY CLOSED EXPANSION CHAMBER COMMUNICATING WITH SAID OPENING; (E) AND ELECTRODE MEANS IN SAID CONDUIT FOR PASSAGE OF AN ELECTRIC DISCHARGE THROUGH THE FOLLOWING SUBSTANCE IN A PORTION OF SAID CONDUIT INTERMEDIATE SAID THROAT PORTION AND SAID DISCHARGE PORTION.
