Capsule Or Pelleted Or Tablet Patents (Class 424/408)
  • Patent number: 6015773
    Abstract: A composition comprising a mononucleate solid crop protection particle coated with a water-insoluble coating material has a diameter in the range of 0.5 to 50.mu.. This composition is made by a process which results in substantial non-agglomeration of the coated particles. In a particular embodiment, a crop protection composition comprises a mononucleate solid crop protection particle coated with either wood rosin, rosin derivatives, waxes, fatty derivatives, sterols, long-chain sterol esters and sulfur. Alternatively, the coating material may be a water-insoluble synthetic latex polymer. The composition may be used in a mixture which also includes a crop protection chemical partner comprising a solid particle. The partner ordinarily degrades the solid crop protection particle when stored or aged together as a solid particle mixture. However, when the composition solid particle is coated, this degradation is prevented.

  • Patent number: 5876740
    Abstract: A weather resistant, rodenticidal bait comprises sweet corn flour, an effective amount of a rodenticide, and water. Additional preferred ingredients include a glutinous flour, flavoring and salt. Preferred rodenticides include diphacinone, brodifacoum, warfarin, bromadialone, bromethalin and their functional equivalents. A preferred method of manufacturing the weather resistant rodenticidal bait of the present invention utilizes cold extrusion techniques. The most preferred method of manufacturing includes the steps of mixing a sweet corn flour, an effective amount of a rodenticide, and water to produce a rodenticidal mixture. In the preferred method, a glutinous flour is also mixed with the sweet corn flour, with wheat flour the most preferred glutinous flour. The rodenticidal mixture is forced through an extrusion chamber and out a nozzle opening, to produce extruded chunks.

  • Patent number: 5874098
    Abstract: An antibiotic and pharmaceutical pellet system and method provides localized sustained antibiotic release as part of a single therapeutic procedure in order to prevent infections at the injection site. The system includes an implanter apparatus for subcutaneously implanting pharmaceutical pellets in an animal through the bore of a hypodermic needle which is operably coupled to a pellet magazine, a pellet magazine, and a plurality of pellets sized to be implanted through the needle and positioned in the magazine for selective alignment of a pellet with the needle. The pellets include pharmaceutical dose pellets and antibiotic dose pellets which are packaged in the magazine in sequential order for delivery of the pharmaceutical dose followed by the antibiotic dose as part of a single injection. The system permits localized controlled and sustained absorption of the antibiotic pellet dose to combat infection in and around the site of the injection.
