  • Patent number: 5629341
    Abstract: This invention is a pharmaceutical composition that inhibits the growth of cancers and tumors in mammals, particularly in human and warm blooded animals. The composition is also effective against viruses. The composition contains N-chlorophenylcarbamates and N-chlorophenylthiocarbamates which are systemic herbicides.
    Type: Grant

    Inventor: James B. Camden
  • Patent number: 5340492
    Abstract: The invention provides a shaped solid, three-dimensional skeleton structure comprising: a relatively rigid, interlocking mesh of neutralized crystalline carboxylic acid. In another respect, the present invention provides an improved cleansing bar which is comprised of the rigid, interlocking mesh of neutralized carboxylic acid, preferably sodium soap fibers. Such preferred cleansing bars can be formulated to have essentially no bar smear. Some cleansing bars comprise surprisingly large amounts of water and other liquids while maintaining their rigidity and excellent smear properties; even when allowed to soak overnight in water.

  • Patent number: 4898477
    Abstract: A self-expanding flexible pouch that can be used as the measuring device for reconstituting a concentrated product contained therein. The flexible pouch includes an extensible stay located in the throat area of the pouch that is biased toward a circular or elliptical configuration but initially held substantially flat in a stressed condition by the pouch's sealed top portion. When the pouch's top portion is removed, the extensible stay expands to its unstressed circular configuration and thereby expands and opens the pouch's throat area. In a particularly preferred embodiment of the present invention, the pouch's bottom section is provided with a pleated bottom gusset panel that is attached to the sidewall panels' inner surface. When the reconstituting fluid is poured into the pouch, the pouch's bottom gusset panel unfolds and drops downward which allows the pouch's bottom section to also expand and assume a substantially tubular configuration.

  • Patent number: 4294876
    Abstract: A tufted material is disclosed having a primary tufting substrate made up of layers of molecularly oriented film. The layers are laminated together in a generally undisturbed condition so that at least two layers have directions of molecular orientation that are perpendicular. The layers are molecularly oriented to the point of splitting parallel to the direction of said molecular orientation under the tufting needles, allowing the needles to penetrate easily, securing the tufts in place, and resulting in good tuft registration.

  • Patent number: 4233235
    Abstract: A continuous process for making aliphatic diperoxyacids comprising continuously adding a dibasic acid having from about 8 to about 16 carbon atoms, sulfuric acid, hydrogen peroxide and water to a continuous stirred reactor. The diperoxyacid formed is continuously withdrawn from the reactor.

  • Patent number: 4113911
    Abstract: Improved tissue, continuous filament nonwoven laminates which are characterized by relatively high strength or toughness, relatively high loft and drape together with low noise or paper-like rattle. The improved tissue, continuous filament nonwoven laminates, while exhibiting a relatively high strength, are comprised of a low tensile strength, low basis weight, lightly bonded or unbonded layer of continuous filament nonwoven which is impregnated with about 50% to about 120%, based on the continuous filament nonwoven layer basis weight, of soft, tacky latex solids. The impregnated continuous filament nonwoven is combined under minimum combining pressures, while in the impregnated moist state between at least two, soft absorbent tissue facing layers prior to drying the laminate and curing the latex solids.
