Abstract: An apparatus (100) for making flexible packaging containers (20, 70, 84) and inserting and sealing discs (22) within the containers in one continuous operation includes a nip roll indexer (116) which intermittently advances free ends of a first web (108) and a second web (110) a distance defining at least a width of a container, a die cut press (112) for forming partially separable flaps in the first web, first and second ultrasonic welders (220, 226) which concurrently seal together the first and second webs along a first longitudinal seal line (258) and at least one transverse seal line (252) so as to create in the webs a series of disc-receiving areas (40) each defined by the first longitudinal seal lines together with two of the transverse seal lines and having an open edge adjacent second longitudinal edges (256) of the webs, a disc inserting apparatus (120) adapted to insert a disc into a disc-receiving area, a third ultrasonic welder (380) which seals the webs together along a second longitudinal seal

Abstract: An arc diverter detects an arc between the cathode and the anode of a glow discharge apparatus and in response to arc detection, actuates a switching network that triggers a pair of switches to allow a capacitor to discharge toward the cathode along a resonant diverting path and recharge the capacitor for subsequent discharge in an opposite direction. This discharge current effectively short circuits the power supply and extinguishes the arc. The resonant diverting circuit includes two resonant diverting paths and four switches configured in an "H" to hold the capacitor in a charged condition. Alternate triggering of the diagonally situated pairs of switches enables the charged capacitor to discharge in one direction along one of the resonant diverting paths and recharge for subsequent discharge in the opposite direction, along the other of the resonant paths. Both resonant diverting paths provide discharge toward the cathode.
