Abstract: ABSTRACT OF THE DISCLOSURE              A machine is disclosed for forming a sleeve of a shrinkable, cellular polymeric material from a pre-decorated web.  The web is processed to provide (1) a partial-depth slit along the longitudinal dimension and (2) cross-dimension pleat.          Pre-decorated shrunken neck labels are formed from the web for overlying the neck and closure and a bottle and includes a pilfer-proof feature.  The label is formed from the processed web by cutting a blank having the cross pleats therein and winding the blank on a mandrel.  A rotary mandrel mechanism is provided with a vacuum at the periphery thereof to hold the label blank in place with the mechanism operating the mandrel to rotate it about its longitudinal axis for wrapping or winding the blank strip thereon.  Several mandrels are carried on a rotary turn of the machine and each mandrel unit includes a hot air nozzle system for heat welding or bonding the overlapped ends of the blank on the mandrel.  Hot air is furnished by the nozzle which extends the length of the over-lapping seam of the blank at a time just before the opposite ends, the leading end trailing ends of the blank, are about to overly one another.  The heat is sufficient upon engagement of the overlapped portion to join or heat seal the material at a side seam and to form a sleeve.  The sleeve is stripped onto the top neck end and over the closure of a bottle to a label position and shrunken to a snug fit, the pleats absorbing wrinkles that occur in shrinking.

Abstract: ABSTRACT OF THE DISCLOSURE         A cargo-carrying articulated ship system having icebreaking capabilities is provided herein.  The system comprises a powered cargo-carrying vessel having an icebreaking hull form, a bow and a stern, and a powered locomotive vessel having an icebreaking hull form, a bow and a stern.  A connection system is provided for connecting the powered cargo-carrying vessel and the powered locomotive vessel together at concave and convex respective bow and stern configurations.  The connection system in-cludes male junction elements (a semi-spherical projection and the nose of the towed vessel)/female junction elements (semi-cylindrical hollow verti-cal outlets in the stern of the towing vessel).  These male/female junction elements restrain longitudinal movement between the connected vessels, yet permit relative vertical movement and allow relative rotational movement. The connection system also includes hydraulic cylinders secured to the lo-comotive vessel with lines secured to the arm end therefrom and tied to the cargo-carrying  vessel.  Interrelated pulling-in on one cylinder and slack-ing  off on the other cylinder controls the lateral movement of the powered cargo-carrying vessel in relation to the powered locomotive vessel.  This operation enables the powered cargo-carrying vessel to be manoeuverable in lateral directions independent of the direction of movement of the loco-motive vessel..Thus a powered cargo-carrying vessel for use in ice infested waters is provided having an optimal split between cargo-carrying capability and propulsion capability.

Abstract: Abstract of the Disclosure A device ror transformation of alternating current-voltage which includes a core, a primary winding subassembly and a sec-ondary winding subassembly.  One or both of the primary and secondary winding subassemblies consists of at least one pair of equal turn and approximately equal resistance windings wrapped co-directionally around the core, and each having an equal num-ber of tapped sections.  A special tandem switch selectively interconnects tapped sections within winding pairs to provide a desired output terminal winding array such that all sections connected through the switch are energized, and are in the cur -rent carrying path at all selected switch positions, with selec-tively seriesed and selectively paralleled portions of the switch-coupled winding pairs being selectively encircuited at each switch position.  The functioning primary and secondary windings are asymmetrically disposed in relation to each other at most of the switch positions, and the leakage reactance is unequal through the several paired windings when they are con-nected by said transformer switch to place less than all of the tapped sections of each in parallel.

Abstract: ABSTRACT An elongated cone like member having a pointed end and a relatively large blunt end with the intermediate portion flaring outwardly from the pointed end to the blunt end, and serrations formed in the member adjacent the pointed end.  The pointed end of the member is plunged into the end of a short length log and the blunt end is struck by a driving maul.  The serra-tions prevent the member from bouncing back out of the wood and the multi-directional flaring of the intermediate portion applies splitting pressure radially in a symmetrical pattern from the point as the member is driven into the wood to thereby split the log where it is weakest.

Abstract: Abstract of the Disclosure A wooden truss structure comprises upper and lower chords, each of which is grooved on the side facing the opposite chord. A web member formed of sheet material, such as plywood, interconnects the chords and fits within the chord grooves. At the web/groove interface, the webs are scalloped to provide alternating alignment guide areas and glue vent areas which extend above the interface and allow the escape of excess glue from the groove. The scalloping, in addition to venting the glue line, forms individual, pressurized glue pockets which assure even glue distribution. The scalloping is preferably provided by pressing the wood web material to compress it at the glue vent areas and thus permit the web member, due to its memory, to expand after contact with the glue. This expansion pressurizes the glue pockets and forces glue from the joint area into the wood further enhancing the expansion process. The web is rigidly bonded to the chord members, all while being aligned by the alignment guide portion. This scalloping is effected along the lateral walls of the web at right angles to the longitudinal dimension of the web and consists of compressing the wood so that the impressions are deeper at their bottom than at their top.

Abstract: HIGH VELOCITY WEB FLOATING AIR BAR HAVING A RECESSED COANDA PLATE                  Abstract of the Disclosure An air bar for floating a running web and having two spaced apart air nozzles through which pressurized air is directed against the web to form a supporting air cushion for the web.  The nozzles are elongated slots extending transversely of the web and which are positioned at each edge of an intervening plate that also is located transversely of and closely adjacent the running web.  The plate has curved edges, one located adjacent each of the slots whereby the air issuing from the slots tends to follow the curvature of the curved edges, thereby tending to direct the two issuing jets of air from the slots towards one another.  The plate, commonly referred to as a Coanda plate, has a recessed portion between the slots and which is located inwardly or below the slots to thereby create a sufficient space between the web and the plate to cause generation of air turbulence, vortexes and eddy currents in the pressurized air zone or cushion between the web and the plate, which results in increased floatation pressure for the web and increased heat transfer of the material, such as printing, which is on the web.
