Abstract: A reverse number identification system is described which allows the called party in a telephone link to identify the telephone directory number of the calling party. This system includes a first system component located at the customer's premises which includes a display for the calling party's directory number. A second system component includes equipment connected to the calling party's telephone line located in the calling party's central office which transmits upon request the directory number of the calling party to the first system component. Each subscriber's telephone line in the central office has a microprocessor controlled transceiver placed between the incoming subscriber's telephone line and the central office switching equipment. Each subscriber's premises includes a first system component designed to receive and display the calling party's telephone number. In operation, the calling party dials the directory number of the called party and the called party responds by answering.

Abstract: Insulation board feeding apparatus feeds successive boards from a pallet stack to a grooving machine to make pre-formed duct sections. The apparatus includes a cable driven elevator assembly, a reciprocating transfer carriage with a plurality of pivotable board-engaging fingers which is reciprocated by an air cylinder, and a guide assembly comprised of two non-driven rollers. The machine of the present invention is simpler, more reliable and less expensive to manufacture than its predecessors.

Abstract: In a machine for packaging articles in a tray carton a first stationary rail section folds up the end panels of a moving tray carton blank to an intermediate position and, after the application of glue to either the end flaps or the end panels, a third stationary rail section completes the operation of folding the end panels of the moving blank up against the end flaps. A second normally stationary section located between the first and third sections maintains the end panels in their intermediate positions. When the machine stops for any reason the second section moves the end panels of the tray carton located at that station into contact with the end flaps to adhere the end panels to the end flaps of the stationary tray carton.

Abstract: A lightweight, precious metal containing, glass fiberizing bushing having a novel power terminal ear arrangement is disclosed. The novel terminal ear arrangement has two relatively thin ears which extend from an area located near the midpoint of each end wall of the bushing, their elongated bases lying generally in the same plane and being generally parallel to the bottom wall of the bushing. The thin ears are spaced a relatively great distance apart but yet are relatively wide. This arrangement minimizes precious metal usage but still provides uniform heating of the molten glass within the bushing.

Abstract: A process and apparatus for the production of glass fiber is disclosed. The process and apparatus are directed to collecting filaments being drawn from streams of liquid glass into a plurality of loosely bound strands of filaments which additionally are not treated with any binders. The strands are then drawn off individually on separated but parallel rotating surfaces to provide the filaments with a desired diameter.

Abstract: A refractory binder including a tackifying agent. The tackifying agent is a montrorillorite clay. The binder is a chromium alumina phosphate mixture with a fluxing agent. The binder may also be a colloidal suspension of alumina, silica or zirconia with montmorillonite clay. The binder is used with refractory fiber to produce a monolithic layer.

Abstract: Apparatus for pushing a loaded open-ended carrier sleeve and folding the trailing dust flaps of the sleeve. Flight bars attached to endless chains located below the path of travel of the carrier sleeve initially move the sleeve. Pusher bars or lugs attached to endless chains located above the path of travel of the carrier sleeve engage the trailing panel of the sleeve and accelerate the sleeve away from the flight bars. Fingers attached to the pusher bars contact the trailing dust flaps prior to the pusher bars contacting the trailing panel of the sleeve and fold the trailing dust flaps before the sleeve is accelerated along its path of travel.

Abstract: A crown support carrier for a plurality of beverage bottles is disclosed. The carrier is designed for retaining bottles having circular flanges formed below the threaded necks of the bottles with the bottles being inserted through neck receiving openings in a flat center section of the carrier. A pair of upwardly and inwardly protruding panels are hingedly attached to opposite sides of the flat center section and serve to stiffen the carrier edge and to aid in the support of the bottles by being positioned at a pre-determined angle below the circular flanges. When so positioned, the upwardly protruding panels engage a portion of the circular flanges to thereby aid in carrying the bottle weight. The upwardly protruding panels also provide a flat graphic area for the placement of advertisments or other printed matter.

Abstract: Clamps mounted on a reciprocal frame grip a web of connected molded fibrous articles and move toward a cutter a distance equal to one article length, thereby presenting to the cutter the connecting portion between adjacent articles and also pulling the next portion of uncured fibrous material into the mold press for shaping and curing. After the cutting operation the clamps open and move toward the mold into position to again grip and feed the web toward the cutter. Connected rows of webs can also be handled by slitting the rows as they move toward the cutter. The articles, which can be quite deep compared to the thickness of the connecting portions between articles, are supported during travel and while stationary by support plates separate from the reciprocal frame. The various components which contact or cause movement or cycling of the apparatus can be adjusted to permit handling of articles and webs of different dimensions.

Abstract: A sleeve-type beverage can carrier with a handle opening in the top panel extending across the entire width of the top panel. The opening further extends into the upper portion of the side panels, terminating in an arcuate edge. Upon lifting the carrier, the top panel between the edge of the handle opening being grasped and the nearest end panel is caused to bow upwardly by the lifting stresses, thereby distributing the stresses through the top panel and the upper portions of the side panels to prevent tearing.

Abstract: A blank for forming a wrap-around carton is delivered to a moving support carriage which is moved to a station where the moving carriage receives a predetermined number of articles to be packaged. The carriage, with the articles resting on the bottom portion of the blank, is moved downstream while cams actuate tucker fingers which pivot up to fold the tuck flaps of the blank toward each other, causing the end and side panels to be elevated. Another cam actuates a pusher bar which pivots up to push the articles. The carton blank and the articles are thus positively moved through subsequent flap folding and gluing stations, avoiding the problems which can arise due to the use of separate means for moving the articles and the carton blank. A cam operated hinged plate is used to segregate the leading articles at the entry to the machine.

Abstract: A laminate of foil and kraft paper is adhered to the upper face of fiber glass insulation so that the exposed foil reflects radiant heat entering the attic through the roof of a building structure. Relatively thick kraft paper supports the very thin layer of foil without causing a fire hazard due to the use of an inorganic adhesive, such as sodium silicate, to bond the two together and also due to the use of a fire retardant water-based adhesive to bond the foil-kraft laminate to the fiber glass. The laminate is preferably perforated to prevent it from functioning as a vapor barrier.

Abstract: A nonprecious metal drain bushing for use in the start-up of a glass melting furnace. The bottom wall of the bushing is relatively wide and thick and is bent downwardly near the ends of the bottom wall to form integral terminal ears. The end portions of the terminal ears are of reduced thickness for attachment by the power clamp. The side walls coverage at an angle down to the bottom wall to facilitate flow of the molten glass through the bushing, and the thickness of the bottom wall and terminal ears is substantially greater than the thickness of the side and end walls.

Abstract: A carton contains a flap on the outer top panel and a flap on the inner top panel, the free edge of the outer top panel flap overlying the inner top panel flap. When a user presses down on the outer top panel flap, it pivots out of the way to allow the user's fingers to fold the inner top panel flap under the top panel structure to provide a handle for lifting the carton. When the fingers are withdrawn, the outer top panel flap is biased upwardly by its arcuate foldable connection to close the handle opening. If the inner top panel flap is contacted by the outer top panel flap as it pivots upwardly, the outer top panel flap pushes the inner top panel flap up to a substantially closed position. Score lines extending from the ends of the foldable connections of the inner and outer top panel flaps to the corners of the carton distribute the lifting stresses to the side panels of the carton.

Abstract: A machine for feeding a collapsed beverage can carrier sleeve to a flight bar conveyor and introducing the sleeve in fully open condition to the pocket of the conveyor. After leaving the feed rolls the collapsed carrier sleeve is moved through a fixed guide by lugs on a movable chain. The end flaps on the upwardly facing side panel are held in place on the guide while the end flaps on the downwardly facing side panel are moved downwardly by a fixed cam surface. The substantially opened sleeve is then either given a final kick by rotating arms or is propelled by the feed lugs to accelerate it into the pocket while at the same time fully straightening and opening the sleeve. The carton dimension corresponding to the length of the pocket is the same as the length of the pocket, resulting in more pockets per conveyor length and permitting operation at slower conveyor speeds.

Abstract: A sleeve-type beverage can carrier having a transversely arranged handle opening in the top panel. The opening is covered by flaps foldably connected to the top panel along the transversely extending elongated edges of the handle opening, each flap being formed of individual tabs which facilitate the folding down of the flap by the fingers of a user. The elongated edges are tapered so that they are the most widely spaced apart midway along their length and the closest together near their ends. This arrangement causes the top panel on both sides of the handle opening to bow upwardly when the carrier is lifted to distribute the lifting stresses through the top panel and the upper portions of the side panels.

Abstract: A multiple article display carton having the end walls of the display cells spaced from the end panels of the carton. Instead of gluing the end closure flaps together the top panel is provided with three foldably connected flaps designed to provide the assembly with a force or friction fit. The first flap is folded down to become the end panel of the carton, the second flap is folded up on the other side of the first flap with the transversely extending side panel flaps therebetween, and the third flap extends from the end panel to the end cell wall to hold the end cell wall in place.

Abstract: A wrap-around bottle carrier wherein the bottle heel cutouts at the ends of the carrier are spaced from the ends a greater distance than normal to increase the strength of the carrier at this area of stress. To permit this arrangement to be used, the shape of the outer or end cutouts is altered by connecting the top of the cutout to the vertical inner side portion of the cutout by a straight cut rather than by the usual curved cut. This allows the edges of the end cutouts to contact the bottles when the carrier is lifted even though, due to the change in dimensions of the end cutouts, the end cutouts are not symmetrically arranged with respect to the centerline of their associated bottles.

Abstract: A machine for feeding beverage cans to open-ended carrier sleeves of varying capacities. When loading relatively small carrier sleeves, inboard conveyors and associated metering screws feed groups of cans to a flight bar conveyor which moves the groups through the open ends of the carrier sleeves. When loading relatively large carrier sleeves, outboard conveyors and associated metering screws are also operated after first replacing the inboard screws with screws able to separate cans into larger groups, the same size as those formed by the outboard screws. This arrangement feeds larger groups of cans which are then fed to the larger carrier sleeves. In one embodiment each conveyor comprises a longer upstream conveyor and a shorter downstream conveyor spaced a short distance therefrom to allow the flight bars to travel through the space between the conveyors when moving from the end of their upward run to the beginning of their horizontal downstream run.

Abstract: A pulley construction for use in a continuously variable power transmission arrangement. The conical working surfaces of the drive pulleys and the driven pulleys are comprised of removable segments formed of material which is relatively erodable so that the conical pulley surfaces will wear away before the drive belt. The segments are to be replaced when their surfaces have been eroded too much. The replacement of the pulley face segments is simpler and less expensive than replacing the belt, and the use of a relatively erodable pulley face prolongs the life of the belt.
