Abstract: A gate pulse generator for a static var compensator (SVC) constituted by a thyristor switched capacitor (TSC) comprises voltage detectors (5u, 5x) for respec­tively detecting forward and reverse voltages (Vu, Vx) applied to antiparallel-connected thyristors (3U, 3X) in the TSC. The antiparallel-connected thyristors (3U, 3X) comprise a plurality of series-connected forward thyris­tors (3U) and a plurality of series-connected reverse thyristors (3X). The gate pulse generator monitors the forward and reverse voltages (Vu, Vx) and determines whether a period (2 ms) in which both the forward and reverse voltages (Vu, Vx) are zero continues for a pre­determined period (2 ms) while reverse-phase sides (3X) of the antiparallel-connected thyristors (3U, 3X) are held in conduction periods (t30 - t40), respectively. The gate pulse generator prolongs an active period (t20 - t31) of a forward conduction period signal (PHSu) by the predetermined period (2 ms). Upon switching (t30) from in-phase conduction to revese-phase conduction, even if some of the plurality of series-connected thyri­stors (3U) are turned off, these thyristors are turned on again within the predetermined period (3U), and an overvoltage is not applied to these thyristors.

Abstract: An in-line machine for attaching elongated, flexible closure tie elements (62) to the individual bag portions of a laterally folded plastic film web (22) being continuously discharged from a bag forming station (20), and being forcibly captured by a winder mechanism (52), engages and drives the moving web (22) toward the winder mechanism (52) by means of mutually spaced inlet, central and outlet drive rollers (90, 92, 94). 
     During operation of the machine, first and second slack portions of the film web (22) are respectively positioned between the inlet and central rollers (90, 92), and between the central and outlet rollers (92, 94). These slack portions are held in vertically looped configurations by a downwardly directed, yielding vacuum force applied thereto. The inlet and outlet rollers (90, 94) are driven at identical speeds corresponding to the constant linear film web output speed from the bag forming station. The central drive roller (92) is alternately started and stopped to sequentially cause a portion of each bag to be momentarily stopped thereon, at which time the machine attaches a tie element (62) to the stopped bag portion. During stoppage of each sequential bag portion, continued rotation of the inlet and outlet rollers (90, 94) lengthens the first film loop (204) and shortens the second film loop (194). When the central drive roller (92) is restarted it operates to equalize the film loop lengths. In this manner, each bag may be momentarily stopped, for tie element (62) attachment purposes, without altering the constant output and input speeds of the bag forming station (20) and winder mechanisms (52), and without imposing undesirably high longitudinal tension force on the plastic film web (22).

Abstract: An improved method of making a color picture tube electron gun (26) includes the selection and assembly of a plurality of cathodes (34) and a plurality of electrodes (36,38,40,42,44,46) longitudinally spaced from the cathodes. The improvement comprises at least three additional steps. First, the amount and direction of electron beam misconvergence at the tube screen, as caused by the thermal expansion of each individual electrode during electron gun warmup, is determined. A first group of electrodes (38,42,44) will cause misconvergence in a first direction, and a second group of electrodes (36,40,44,46) will cause misconvergence in a second direction. Second, the individual contributions of the electrodes to misconvergence during tube warmup are summed. The net effect of thermal expansion of the entire electron gun is a misconvergence in the first direction. Third, at least one of the electrodes (38,42) in the first group of electrodes is formed from a material having a lower coefficient of thermal expansion than the coefficient of thermal expansion used in the first step of determining misconvergence caused by the thermal expansion of each individual electrode.
