Abstract: A creel is used with a winder having a predetermined width and operable to draw in across this width in a normally horizontal longitudinal transport direction a warp of filaments from respective bobbins. The creel comprises a support frame having respective supports for the bobbins and having a pair of generally like sides each provided with a respective half of the supports. The sides are elongated in the transport direction and have downstream ends spaced by at least the winder width, upstream ends more closely spaced, and inner faces turned transversely inward toward each other. Respective deflectors on the inner faces of the support sides guide the filaments inward and transversely of the transport direction from the respective supports and then longitudinally in the transport direction to the winder. The filaments normally run from the deflectors to the winder without touching any substantial guide structure.

Abstract: A switching isolated single transistor forward converter which performs demagnetization and snubbing functions with the same network. The transformer stored energy and the energy stored during snubbing are transferred to the load by the network during the dead time of the switching cycle.

Abstract: A switching regulated push pull converter which includes voltage and current feedback loops to provide a highly regulated output voltage throughout a 100 percent load range. This circuit also provides a semi-regulated auxiliary output voltage which can be loaded beyond 100 percent of its load range with no minimum load requirement on the highly regulated output voltage. A direct current drive circuit for the push-pull power switches provides a transformerless proportional drive and means are provided to compensate for transformer asymmetry.
