  • Patent number: 5913672
    Abstract: A chum delivery assembly for facilitating the rapid and strategic dispersement of chum along a bottom surface of a body of water in order to attract fish, the assembly including a containment member having a base, a surrounding wall surface, and an upper surface which together define an open interior chamber. The open interior chamber is structured to contain a quantity of chum therein, and a lowering line is included and structured to adjustably lower the containment member to a desired delivery location. The base of the chum delivery assembly includes a generally open configuration so as to permit the free passage of the chum therethrough from the open interior chamber, with a rigid panel being provided and disposed to selectively cover the base so as to prevent the free passage of chum through the base until desired.

  • Patent number: 5480577
    Abstract: Wax-encapsulated particles having a core particle or an aggregate of core particles selected from the group of an organic peroxy acid, a diacyl peroxide, an inorganic peroxygen compound, a bleach catalyst, a peroxygen bleach precursor and mixtures thereof together with 0.01% to about 5% by weight of a surfactant. The resulting particles exhibit release rates from their capsules and dissolution rates comparable to uncoated core materials.

  • Patent number: 5409633
    Abstract: The invention relates to bleach compositions containing, as the bleach, a hydrophobic peroxyacid which is sterically bulky, so that the smallest cross-sectional area of the peroxyacid, defined by multiplying together the two smallest dimensions of the molecule, is from 30 to 80 .ANG..sup.2. Preferred are peroxyacids containing a tertiary alkyl group, a norbornane ring or an adamantone ring. Such peroxyacids are effective for the bleaching of stains, especially hydrophobic stains, with low accompanying dye damage.
