Abstract: A metal container which includes two drawn container halves joined by an injection molded plastic ring. The container halves can be identical and of low profile, with upstanding walls terminating in formed edges of substantially the same size and shape. The ring includes a pair of opposed channels sharing a common base, and the formed edges of the respective container halves fit into the opposed channels of the ring. The channels and formed edges are adapted to provide tailored fitting and retention characteristics, so that one of the container half is gripped more securely by the ring, and the other container half is more readily removable.

Abstract: An informative card, such as a baseball trading card, has a rectangular shape and is made of sheet metal in such a way that it is free of pointed corners or exposed raw edges. The informative card comprises a single-layer metal blank which has a burr in the form of an upstanding pointed ridge along the periphery of the blank. A protective film, such as a layer of varnish, is applied on the card to cover the side with the burr so that the burr is shielded.

Abstract: The specification discloses an extrusion billet quenching system which directs a continuous circular curtain of water onto a billet to be quenched. The water delivery system is a spray ring defining a continuous opening about its entire circumference. The opening is defined by a pair of plates. Push and pull screws enable the width of the opening to be carefully adjusted. A reciprocating billet pusher assembly includes opposite cantilevered heads for pushing billets through the ring in either of two opposite directions.

Abstract: The specification discloses a dynamic self-adjusting taper quenching system for producing isothermal extrusions in a nonferrous extrusion operation. The quenching system includes a quenching unit, a computer for controlling the quenching unit, and an interface for reading the extrusion press ram pressure. A target quenching profile is stored in the computer. The computer samples the ram pressure during extrusion of a quenched billet and adjusts the target quenching profile for subsequent billets as a function of the sampled pressures.

Abstract: An informative card such as a baseball trading card is made of sheet metal and is formed so as to be free of sharp edges and pointed corners. Flattened hems around the periphery of the rear side of the card define a raised framing border around indicia which is printed on the rear side. The front side of the card is displaced rearwardly inboard of the hems so as to leave raised peripheral front ledges which define a raised and substantially uninterrupted border around indicia on the front side.

Abstract: A plastic dispensing fitment and a plastic screw-on cap are connected in nested relation by an ultrasonic weld. When the cap is initially screwed onto the neck of a jar, the fitment is forced over the neck with a snap fit. When the cap is first unscrewed, the weld breaks to separate the cap from the fitment and enable removal of the cap from the jar while leaving the fitment attached to the jar.

Abstract: An extrusion pulling apparatus wherein an extrusion puller is guided from above and below for movement along an extrusion line from an extrusion press. The upper guide comprises a T-shaped beam with rollers mounted on the puller for rolling along vertical surfaces of the beam. The lower guide is formed from a multi-face beam, for example, a hexagonal beam, wherein rollers mounted on the puller roll on guide face surfaces which have an included angle between them of about 60.degree.. The upper and lower guides can be reversed.

Abstract: A fitment made of plastic and adapted to be telescoped over the neck of a jar to facilitate dispensing of the contents of the jar. The fitment includes a top wall having a spoon or pour opening adapted to be selectively closed by a flap which is hinged to the top wall to swing between closed and open positions, the flap being formed with sift holes to allow the contents to be sifted from the jar when the flap is closed. The lower sides of the top wall and the flap are flat and, when the flap is closed, lie in a common plane so as to define a flat and planar surface for supporting and backing a paper-like disc for initially sealing the jar. A circumferentially continuous skirt depends from the top wall and engages a bead on the neck of the jar to hold the fitment on the jar. When the flap is closed, a lift tab on the flap fits into a notch in the top wall and overlies an arcuate section of the skirt.

Abstract: A control system is provided for coordinating and monitoring material flow through a nonferrous extrusion facility. The system maintains first-in/first-out queues between stations within the facility to improve tracking of the material through the process. The extrusion equipment is controlled in response to the queues and to stored job information to move the material efficiently and automatically through each station within the facility.

Abstract: The hinged flap of a plastic container closure is molded while in an open position and, during molding of the flap, an elongated tear-away strip is formed along the front edge of the flap and is integrally connected to the flap by tearable webs. After the newly molded flap has first been closed, the strip is anchored releasably to the top panel of the closure and prevents the flap from opening during shipment of the container, the strip also serving as a visual indicator that the seal of the closure is intact. Anchoring of the strip is effected by pins which project upwardly from the panel and which are ultrasonically welded to the lower side of the strip. The closure is opened by lifting and pulling on the strip to break the welds at the pins and thereby enable the strip to be torn completely away from the top panel and the flap and to free the flap for swinging to an open position.

Abstract: A tube having a tube body made of laminations of plastic and metal foil and formed with an integral frustoconical breast. A plastic fitment with a frustoconical skirt is telescoped with and is bonded to the breast and includes an integral cap which is adapted to be swung between open and closed positions.

Abstract: A method and apparatus for removing an extruded profile shape from an extrusion press efficiently and economically during an extrusion operation. A first and second extrusion puller are mounted on suitable guide for movement along an extrusion line. One of the extrusion pullers receives and grips a profile shape as it is extruded from an extrusion press, and this puller exerts a pulling force on the profile shape. The first puller can pass off the profile shape to the second puller as the profile shape is extruded, thereafter the second puller would grip and pull the profile shape and the first puller would release its grip. When it is desired, or necessary to remove the profile shape from the extrusion press, the puller which is not gripping the shape grips the profile shape and a shear within the press shears off a butt portion of the billet. Then, both pullers, in tandem, apply a pulling force on the profile shape away from the extrusion press. The profile shape is stripped from the die.

Abstract: A method and apparatus for conditioning an aluminum billet for extrusion from an extrusion press. The billet is first heated above the solutionizing temperature for the MgSi phases in the aluminum matrix, then the billet is cooled below the solutionizing temperature to an adequate hot working temperature. Preferably, a temperature gradient is created along the length of the billet wherein one end of the billet is at or above the hot working temperature and the other end of the billet is cooled to a temperature below the hot working temperature. Thereafter, the billet is placed into the extrusion die, the hot end adjacent the die and the cool end adjacent the ram of the extrusion press. The billet is then extruded producing an extruded product with uniform properties along the length of the product with minimal defects such as tearing or hot shorting.

Abstract: An extrusion puller which comprises an upper jaw, a lower jaw, and means for mounting the upper and lower jaw relative to each other. The upper jaw comprises a plurality of jaw fingers with radially extending gripping teeth circumferentially spaced around the bottom portion of the tooth wherein the attack angle between teeth and the spacing angle between adjacent teeth is selected so that substantially full penetration of at least one of the gripping teeth into the workpiece is achieved without interference from an adjacent tooth. The lower jaw comprises a serrated upper surface comprising a semi-circular scalloped configuration of a plurality of peaks and valleys. The combination of the upper jaw and lower jaw configuration allows for increased gripping strength to be exerted on the workpiece and thereby avoid defects within the extruded workpiece.
