Abstract: Inorganic fibrous pipe insulation in the shape of a tube comprising outer and inner flexible sheets on the outer and inner cylindrical surfaces of the tube. A majority of the fibers are at right angles to the flexible sheets and therefore extend radially of the pipe to offer good compression resistance to impact. By using substantially non-stretchable material for the inner sheet a fibrous layer whose fibers are generally perpendicular to the layer can be permanently formed into generally cylindrical shape. For insulation designed to cover very small diameter pipes the thickness of the fibrous layer is varied to provide fewer adjacent the inner flexible sheet than are adjacent the outer flexible sheet.

Abstract: A carton for packaging a plurality of articles and adapted to have the top removed in order to function as a display carton. Front and back panel flaps used in forming the front and back panels of the carton contain tear strips, as do the side panels and the dust flaps extending from the side panels. The resulting carton structure contains a tear strip extending completely around the perimeter of the carton to allow the top to be removed.

Abstract: A wrap-around beverage carrier designed to carry four bottles. The bottom panel comprises two overlapping interlocked flaps foldably attached to the side panels, the overlying flap having primary locking tabs in engagement with primary locking slots in the underlying flap. The underlying flap further has a single centrally located secondary punch-style arrow-shaped locking tab which engages a secondary locking opening in the overlying flap. The overlying flap also has two tertiary locking tabs which engage tertiary locking openings in the underlying flap. The primary locking tabs consist of either a single or two closely spaced centrally located oversized position locking tabs and two outwardly spaced undersized position locking tabs, the oversized position tab being operable when oversize bottles are in the package and the undersized position tabs being operable when undersize bottles are in the package.

Abstract: A high efficiency luminaire possessing high angle brightness control. Transverse high angle brightness control is provided by a substantially parabolically shaped reflector and longitudinal high angle brightness control is provided by a trough like lens assembly including a plurality of trough shaped lenses and screening means adjoining one another.

Abstract: A machine for receiving a handle strip from a dispenser, rotating the strip to align it with a predetermined location on a moving carton blank, and applying the strip to the blank. A vacuum head for gripping the strips is carried by an arm mounted for rotation about a horizontal axis extending transversely of the moving blanks. The vacuum head is rotated through rotation of a pinion, which itself is rotated by a reciprocating rack. A cam follower mounted in a stationary cam causes the rack to reciprocate, thereby postively moving the rack in both directions.

Abstract: A sleeve-type beverage can carrier with a handle opening in the top panel extending transversely of the folds connecting the top panel and the side panels. Tabs foldably connected to the transversely extending edges of the handle opening meet at the midpoint of the top panel, and slits extend from one of the handle opening edges through the folds and into the upper portions of the side panels. When the carrier is lifted, the top panel between the slits and the end panel nearest to the handle edge being grasped is caused to bow upwardly, and the lifting stresses are distributed through the top and side panels to prevent tearing.

Abstract: Fiber glass insulation batts are packaged by delivering them to the bottom of a stack of batts, then compressing the stack with a compression plate or platen. The compressed stack is pushed by the platen against a web of packaging film and into a hopper. The web adjacent one side of the stack is then moved over the top face of the stack to enclose it, and is heat welded to the web adjacent the other side of the stack. The web is severed intermediate the weld to separate the package from the web, leaving only a single weld in the package. The stack can be compressed by a dished platen to concentrate the greatest platen pressure at the periphery to avoid damaging the major portion of the surface of the batt contacted by the platen.

Abstract: A paperboard wrap-around article carrier which has end panels foldably connected to the top panel and to gusset panels. The gusset panels allow the end panels to be folded and maintained in a substantially vertical position. The end panels extend beyond the lowermost ends of the gusset panels so that the foldable connections between the gusset panels and the end panels is minimal, thus minimizing the cumulative memory of the fibers in the foldable connections to prevent the forces generated by the memory from unfolding the end panels and snapping them up out of place.

Abstract: A basket-type carrier in which the cells are longer than they are wide in order to receive articles which are elongated in transverse cross section. The blank for forming the carrier contains spaced centrally located support panel sections which are foldably connected to riser panel sections and to the ends of partition straps. The folds connecting the center support panel sections to the partition straps are located between the folds connecting the side panels to the end panel sections and the folds connecting the end panel sections to the riser panel sections.

Abstract: A new and improved mounting arrangement for electrical components in a luminaire in which the electrical components are mounted on an electrical plate which is detachably secured to a support plate with quick disconnect means being provided for detaching said electrical plate from said support plate.

Abstract: A belt and pulley construction for use in a continuously variable power transmission arrangement. In one embodiment the conical working surfaces of the drive pulleys and the driven pulleys are comprised of removable segments formed of relatively erodable friction modifying material so that the conical pulley surfaces will wear away before the drive belt. In another embodiment the drive belt, whether comprised of a rubber compound or of metal, contains wear faces or pads which contain friction modifying material. Traction between the belt and the pulleys can thus be controlled by members other than solely through the tension of the drive belt.
