Abstract: The present invention relates to a devices and methods for killing and/or debilitating pathogenic microorganisms in or on a patient's body, such as light-sensitive bacteria including helicobacter pylori and/or propionibacterium acnes. A chemiluminescent light source provides electromagnetic radiation having predetermined wavelengths in the visible spectrum. The light wavelengths are selected for absorption by naturally-occurring photosensitive chemicals produced by the patient's body.

Abstract: A drum- or barrel-unloader comprising a stand for supporting a drum or barrel in right side up and inverted orientations, and an elevator for engaging the stand. The stand includes a hopper for receiving the drum contents when the drum is inverted. The hopper is mounted for both gross and fine adjustment between a first position away from the top of the drum, and a second position in engagement with the top of the drum. Gross adjustment of the hopper is provided by inserting an apparatus into aligned holes in two slidably engaged channel sections. Fine adjustment of the hopper is provided by a threaded apparatus on each of two threaded studs, each of which extend from an end of a channel section and are inserted into an apparatus for providing holes on generally opposite sides of the hopper. For fine adjustment the threaded apparatus are loosened and tightened on the threaded studs against the apparatus for providing holes. The elevator comprises first and second frame portions.
