Abstract: Abstract A horizontal deflection start-up circuit operates in the absence of trigger pulse normally derived by an AFPC loop.  During normal operation, the AFPC loop generates the trigger pulses based on a synchronized phase relationship with sampled flyback pulses.  During receiver start-up, the flyback pulses are not present and no trigger pulses are generated.  The start-up circuit provides auxiliary pulses which occur later in time than the normal occurrence of the trigger pulses.   Means are provided for applying the auxiliary pulses to the horizontal deflection circuit only in the absence of normal trigger pulses.

Abstract: PARISON HANDLING ASSEMBLIES & METHODS FOR HANDLING PARISONS       ABSTRACT OF THE DISCLOSURE   A parison handling assembly receives tubular plastic parisons from a random bulk storage, orients the parisons, and feeds the parisons in a controlled manner to one or more blow molding machines. Parisons are stored in the random bulk storage and fed at a controlled rate by a metering apparatus to a parison orienter which orients the parisons into a closely grouped arrangement wherein the parisons are both upright and side-by-side. The parisons are fed from the parison orienter to a parison escapement mechanism which holds the parisons temporarily. The escapement mechanism is actuated to release parisons into a parison transporter depending on the production demands of the individualblow-molding machines. Released parisons, from the parison escapement mechanism, move along the parison transporter to be pushed axially into stuffer tubes. The stuffer tubes hold the parisons in properly oriented, end-to-end relationship f or delivery to the actual loading station of the blow-molding machine.
