    Abstract: An apparatus and method for making a gradient gel. The present invention in one embodiment is a gel-making system that has a reservoir for holding a solution. The reservoir is connected to a movable arm through a tubing. The tubing has two ends: one end is in fluid communication with the reservoir; and the other, an open end, is received by the movable arm. A gel holder having an internal gel chamber is placed underneath the movable arm for receiving the solution. In operation, the movement of the movable arm causes the open end of the tubing to move along with it and the open end of the tubing delivers the solution in motion to the internal gel chamber to form the gel.

  • Patent number: 6224891
    Abstract: This invention relates to the treatment of diarrhea and related conditions caused by pathogenic E. coli infection. More specifically, this invention is drawn to the unexpected discovery that by administering a composition which binds and removes the shiga like toxins (SLT) produced by pathogenic E. coli whenever an antibiotic is administered, improved treatment is provided. Novel compositions containing both antibiotic and toxin binding composition and methods of treatment which use simultaneous administration toxin binding composition whenever antibiotic is administered are provided. These compositions and methods kill the enteric E. coli organisms which produce the conditions and neutralize the SLT produced by the organisms and/or released from the organisms when they are killed. Thus, these compositions and methods are better able to ameliorate the symptoms of the infection and inhibit progression of this infection into hemolytic uremic syndrome (HUS) than conventional treatment.

  • Patent number: 6190654
    Abstract: A light reflecting fish attractant comprised of mica flakes is provided. The mica flakes are cast into the water where they slowly sink to the bottom. During their descent, they cascade wildly with the eddies and currents of the water. The light which filters down into the water is reflected off the mica, causing a glittering or flashing. This reflected light attracts fish into the area. The mica flakes are chosen to be sized in the range of 0.001 inch to about 3.0 inch in length, in the range of 0.001 inch to about 3 inch in width and about any size larger than 0.001 inch in thickness. This size range permits the mica flakes to approximate the common sizes of fish scales. The mica flakes giving the appearance of fish scales attracts predator fish to the area where the mica flakes are introduced. After introducing the mica flakes to the water, the sportsman would introduce the fishing line to the area where the flakes have been placed.

  • Patent number: 5968540
    Abstract: Hydrodynamic baits for the control of orthopterous insects are disclosed which contain an attractant, a humectant and a gel former. The baits are designed to function in harsh and/or dynamic microclimates such as for example commercial kitchens or outdoor environments subject to typical circadian influences such as temperature and moisture. A further advantage of the disclosed baits is their lack of attractiveness to mammals.

  • Patent number: 5954958
    Abstract: A method for manufacturing and using a dialysis collection bag, and the dialysis collection bag itself. A collection bag is fabricated with a sterilization tablet therein, having a soluble coating over a sterilization agent. When the collection bag is filled with used dialysis solution at the completion of the dialysis therapy, the soluble coating dissolves over a known period of time such as about 30 minutes. The delayed dissolution allows time to take a specimen sample of the unadulterated used dialysis solution. When the dissolution of the coating is completed, the tablet releases the sterilization agent to sterilize the used dialysis solution, so that pathogens are destroyed to prevent the transmission of disease in the event the collection bag is disposed of improperly.

  • Patent number: 5955094
    Abstract: Intercalates formed by contacting an activated layered material, e.g., an activated phyllosilicate, with an intercalant pesticide to intercalate an intercalant pesticide between adjacent platelets of the layered material is disclosed. Sufficient intercalant pesticide is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 .ANG. (as measured after water removal to a maximum of 5% by weight water) up to about 100 .ANG., and preferably in the range of about 10 to about 45 .ANG., so that, if desired, the intercalate can be exfoliated into individual platelets. The intercalate can be combined with an organic liquid to form a viscous composition for delivery of a pesticide compound. Alternatively, the intercalate can be exfoliated prior to combination with the organic liquid. The intercalated complex also can be admixed with solid particles to provide a granular, dust, or wettable powder pesticide composition.

  • Patent number: 5912029
    Abstract: A compound for attracting fish is disclosed which may be applied as a coating on an article. The compound when applied as a coating on an article will progressively dissolve in water and release a fish attractant. The compound includes (a) water soluble jell forming component, (b) a water soluble adhesive component, (c) a carrier component, and (d) a fish attractant component. The compound is produced by mixing the fish attractant with the water soluble carrier and combining the mixture with the water soluble adhesive and jell forming component.

  • Patent number: 5912004
    Abstract: A fungicidal composition in the form of an aqueous emulsion is formed from 3-iodo-2-propynyl-N-butylcarbamate (IPBC), 2-(thiocyanomethylthio)benzothiazole (TCMTB), polyoxyethylene triglyceride, polyalkylene glycol ether, xanthan gum and dipropylene glycol. The composition is formed by adding a molten blend of polyoxyethylene triglyceride to a blend of IPBC and TCMTB, and then adding thereto a solution of xanthan gum in dipropylene glycol and water. The composition is particularly suited for the preservation of wet blue hides as obtained in the leather industry, and may also be used in the preservation of organic coatings delivered from aqueous media.

  • Patent number: 5902589
    Abstract: Aqueous solutions of hydratable polymers are prepared by hydrating a hydratable polymer in water without agitation sufficient to shear the molecular structure of the polymer thereby maintaining intact the polymer's molecular structure thereby providing a structurally uniform composition. The resulting solutions are sticky and tacky and are useful in controlling insects and for other uses. The resulting solutions can be dried to form powders. The resulting products readily degrade, are non-toxic, and non-ionic, and hence environmentally benign.
