  • Publication number: 20030067176
    Abstract: A door security bar assembly includes inner and outer wall anchor plates at each side of the doorway, which sandwich the wall structure therebetween. The external plates preclude forcing the door to pull any inner attachment screws from the inner structure, as is possible with most prior door security bars. The present bar includes a combination hinge and pivot attachment at the hinge side of the doorway, allowing the bar to be pivoted parallel to the hinge line for storage when not deployed across the door. The bar also telescopes, with a spring urging the bar to a fully extended position to ensure engagement with the retaining fixture at the latch side of the door. A lock or hasp may be installed for further security, if desired. An additional door knob retainer may be provided optionally, for precluding knockout of the door knob or lock to access the latch.

  • 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.
