  • Patent number: 4795651
    Abstract: Disclosed is a method for separating mycotoxin-contaminated grains, kernels, seeds and nuts, from uncontaminated whole grain seeds, whole or split kernel nuts and seeds to obtain a substantially uncontaminated supply source of these foods.

  • Patent number: 4785030
    Abstract: Latex compositions suitable for applications requiring surface hydrophilicity are disclosed. The compositions comprise: (1) a liquid phase selected from the group consisting of water, water-miscible solvents and mixtures thereof; and (2) latex particles dispersed in the liquid phase. The particles comprise an elastomeric hydrophobic core and a hydrophilic "shell" which is integral with the core and which colloidally stabilizes the latex particles in the liquid phase. The shell comprises moieties L-Q attached to the core, wherein Q is a nonionic group end-capped with a cationic moiety, and L is a linking unit. When the liquid phase is removed, the particles are capable of forming an elastomeric film having a substantially permanent, cationic, hydrophilic surface. The cationic moiety helps the latex particles become attracted to anionic surfaces such as cellulosic materials.

  • Patent number: 4784271
    Abstract: A shipping carton or container that can be readily opened and converted into a display tray without having to use a knife or other sharp instrument. The carton is formed from a blank having four sidewalls and hingedly connected top and bottom end panels. The sidewalls have a line of severance running circumferentially around the carton that defines a continuous butt joint separating the carton into a top cover section and a bottom tray section. A wide tape having a narrow tear filament or strip attached to its inner surface is adhesively attached to the sidewalls' outer surface such that it bridges the butt joint and holds the carton's top and bottom sections together, the tear strip being substantially superimposed over the butt joint. Pulling the tear filament neatly splits the wide tape and separates the carton's top and bottom sections.
