Abstract: A quick change roll-fed high speed labeling system for improving labeling speed and precision label placement comprises a conveyor for moving articles to be labeled, and an infeed screw assembly for spacing and stabilizing the articles. The infeed screw assembly comprises a feedscrew having a plurality of pockets for receiving and properly spacing successive incoming articles, which has a gear drive, and means for pivoting the feedscrew both vertically and horizontally. Additional system elements include a rotatable starwheel assembly having a plurality of spaced pockets for receiving individual ones of the articles therein, a rotatable vacuum drum assembly, and a supply of roll fed labels, wherein the labels are dispensed singly onto a label receiving face of the rotatable vacuum drum assembly. The rotatable vacuum drum assembly comprises a unique three-ported valving system, for reducing or eliminating glue clogging problems during system operation.

Abstract: A fluid separator is provided in the air venting apparatus of a fluid power system working fluid reservoir to separate and return to the reservoir working fluid droplets carried from the reservoir with air expelled through the venting apparatus.

Abstract: A bulk yarn formed from a plurality of multi-filament yarns having alternating compact and open segments. The compact segments include first and second plaited portions which are twisted in opposite directions. The open segments of the yarn are defined by loosely bundled multi-filament yarn. The apparatus for bulking the yarn includes an elongated housing having a longitudinal bore extending therethrough. Pressurized air passes through diametrically opposed passages for contacting the yarn as it passes through the bore for producing the bulking effect thereon.

Abstract: A heating coil in a firebox above a burner is connected to a hot water radiator positioned between the firebox and a hot air outlet. A usual short flue pipe between the firebox and a draft diverter is replaced by a plurality of longer flue pipes of smaller diameter spaced above the firebox for transferring heat to air that is flowing to space that is being heated.
