  • Patent number: 4155895
    Abstract: An ink composition is provided which is suitable for use on bare metal, for example, tinplate or aluminum as well as on such metals having organic coatings applied to surfaces thereof. The compositions may also be used on plastic containers or retortable pouches comprising plastic or plastic-metal foil laminates. The inks are suitable for use in contact printers or in jet ink printing techniques. The ink compositions are thermotropic, i.e. they change color in the presence of steam at elevated temperature and are useful as sterilization indicators. The inks comprise essentially a binder resin component, an alcohol solvent and a colorant which reacts in the presence of steam at elevated temperature to produce a visible and permanent color change.

  • Patent number: 4155690
    Abstract: Cross-linked polyethylene is continuously produced by injecting dicumyl peroxide (Dicup) into the polyethylene in the mixing barrel of the extruder. The Dicup injection nozzle extends into the flight of the screw of the extruder and the flight is interrupted, or notched, at this position. This enables the Dicup to be injected at a position about half way between the extruder barrel wall and the core of the screw and also avoids pulsed back-pressure on the feed pump for the Dicup. A closely controlled and constant ratio of cross-linking agent to raw polyethylene is obtained.

  • Patent number: 4155692
    Abstract: Containers are formed with latch openings and a reinforced region adjacent to each opening, molded in one operation from a softened sheet of organic polymer material. The latch opening is formed by vertical shearing of the sheet from a predetermined area of one of the mold dies during the closure of the molds. The sheared-off material is compressed against adjacent portions of the sheet to define a reinforced edge of the aperture. Accretion of sheet material adjacent the aperture region adds strength and rigidity to the container wall and eliminates removal of waste material separated during formation of the latch opening.

  • Patent number: 4153561
    Abstract: Compositions in the form of aqueous emulsions containing salts of N-alkyl-.alpha.-sulfosuccinic acid amides, fatty acid amide sulfates or glycerin ether derivatives, polyethylene glycols and non-ionic dispersing agents. These emulsions are very stable to storage. They are used for the treatment of textile materials. Preferably they are added to the padding liquor in continous pad-dyeing or printing processes for textiles including carpets of synthetic fibers. They can also be used in space-dyeing processes. They give a soft feel to the textiles treated therewith and also provide a good wetting of the textile goods. On synthetic fibers also an anti-soiling effect has been observed.
