Abstract: Apparatus and methods are disclosed for a high speed production line in which a container is wrapped with a plastic label comprising a foam polystyrene layer, there being means to move a leading edge of the label to the periphery of a rotating vacuum drum, means to apply methylene chloride to the underside of the foam layer to form finite areas on the leading label edge and a finite area on the trailing edge. The finite areas have therein a rapidly solidifying tacky solution of the foam polymer in methylene chloride, the tacky viscous solutions rapidly solidifying to form an adhesive bond. The solvent-applied label is quickly moved to a label wrapping station where it is wrapped around a container, the finite areas on the leading edge tacking the label to the container, and the finite area on the trailing edge forming a cohesive bond on the seam formed by the overlapped label ends.

Abstract: A process for forming a doped oxide film and a doped semiconductor suitable for electronic applications wherein a silicon tetraalkoxide is reacted with a limited amount of water to produce a low molecular weight, soluble polyorganosiloxane. The polyorganosiloxane is subsequently admixed with a soluble dopant element compound to form a homogeneous, polyorganosiloxane-dopant compound solution. The solution is coated onto a semiconductor wafer substrate material and heated to produce an impurity doped semiconductor wafer suitable for electronic application.

Abstract: A method is disclosed for thermally conditioning an essentially tubular parison of polyethylene terephthalate material to a desired orientation temperature at which the polyethylene terephthalate material can be biaxially stretched. The method comprises the steps of heating the parison by applying heat to the exterior surface thereof until the surface reaches a maximum heating temperature less than the temperature at which the polyethylene terephthalate material begins to crystalize and then cooling the heated exterior surface of the parison to remove the heat therefrom while the heat within the wall of the parison diffuses therethrough to raise the temperature of the opposing interior surface toward the desired orientation temperature.

Abstract: A blow molding apparatus wherein a plurality of sets of molds are mounted on a wheel rotatable about a horizontal axis and each set of molds comprises mold sections that are movable radially inwardly toward and away from one another to define a blow molding cavity wherein the plastic material is extruded from an extruder having an extruder head downwardly between the open molds, comprising a base plate, a platen pivoted on the base plate for movement about a vertical axis, such that an extruder mounted on the platen and having an extrusion head can be adjusted radially of the wheel to align the extruded plastic material with the plane of juncture of the mold sections.

Abstract: An apparatus for uniformly winding elongate sheets of punched material, typically used for grouping and packaging beverage containers, includes a reciprocating shuttle which evenly distributes the material as it is wound on a reel. The shuttle includes a plurality of adjacent sheet receiving slots which permit simultaneous reciprocation and even winding of a like plurality of sheets and a moveable elongate guide member which is moveable between a raised loading position and a lowered, retaining position. Mechanism is also included which permits adjustment of the reciprocatory stroke of the shuttle as well as of the center about which such reciprocation occurs.

Abstract: The present invention provides, without the drawbacks accompanied by the use of hot melt adhesives, an attractive, easily recycled labelled container, the label, on its underside that is adjacent the container when applied, being provided with a finite area on its leading edge and a finite area on its trailing edge, by applying thereto a solvent for the polymer in each of the finite areas, the finite areas comprising a viscous tacky solution of the polymer in the solvent, the solidifying solution being sufficient to tack and bond the label to container during wrapping.After the label is wrapped around the container, the bond between the container and label becomes weaker as the solidifying solution hardens so that later the label can be easily and cleanly stripped from the container for recycling.
