Abstract: AN IMPROVED SHUTDOWN CIRCUIT FOR A SWITCHING POWER SUPPLY             ABSTRACT OF THE DISCLOSURE      A switching mode power supply provides a D.C. output voltage having a value related to the duty cycle of the supply's controlled oscillator produced signal.  The in-ventive shutdown circuit inhibits operation of the supply if the duty cycle increases to a value indicative of failure of the supply to produce a minimum desired output voltage.          Operation of the supply is inhibited for a predetermined shutdown interval following which a restart cycle deactivates the shutdown circuit for a period to allow the supply to attempt to establish its desired output.

Abstract: LINEAR TAIL SEALER     ABSTRACT OF THE DISCLOSURE   A machine which is operative for handling a roll of wound sheet-like material having a loose tail end  . includes rollers which rotate the roll in the rewinding direction, blowers which unwind the loose tail end off the roll during rotation, and a delivery table upon which the unwound loose tail end settles for the appli-cation of glue.  A first sensor detects the unwinding of the tail end off the roll and activates a normally deactivated second sensor which turns off the rollers when the tail end reaches a predetermined location on the delivery table.  Adhesive is next applied to the stationary tail end by a glue gun which is movably mounted on a pneumatically controlled carriage assembly.          The glued tail end is thereafter rewound upon the roll, and the roll is subsequently ejected from the machine.          A third sensor detects the initial presence of the roll upon the rollers and will initiate ejection of the roll after a predetermined time period elapses, regard-less of operation of the glue gun.
