Portable Purifying System
A portable purifying system for improved filtering and/or separating of cleaning solutions such as solvents, particularly those used in parts washers. The purifying system utilizes a removable reservoir to provide a smaller reservoir within a larger reservoir such as a parts washer. The portable purifying system provides an apparatus and method of use to perform the following steps: using re-circulating solvent from the larger reservoir, washing oily parts in such manner that oily residue from the washed parts is deposited in the smaller reservoir; separating cleaner portions of solvent from dirtier portions of solvent within the smaller reservoir using density differences to separate by gravity action cleaner portions from dirtier portions; moving the cleaner portions of solvent into the larger reservoir; and periodically emptying and cleaning the smaller reservoir.

Waste Oil Electrical Generation Systems
An on-site electrical power generation system utilizing environmentally hazardous waste oils as a combustible fuel. The disclosed invention utilizes environmentally hazardous waste oils generated by one or more on-site processes, such as, for example, by the maintenance of transportation vehicles. In addition, the system is adapted to provide local space heating and hot water as a byproduct of the combustion process.

System For Producing Enterocytozoon Bieneusi Live Organsisms
Described is a system for efficiently producing live Enterocytozoon bieneusi (E. bieneusi) organisms using laboratory animals, preferably Mongolian gerbils. Some important steps are: providing at least one breeding pair; administering to each of such breeding pair a sufficient antibiotic in sufficient dosage to destroy essentially all parasites which might be passed to offspring, especially Trichomonas; permitting such breeding pair to produce and rear offspring as production animals; preventing breeding by the production animals by separating males from females in separate cages; immune-suppressing each production animal sufficiently to permit propagation of live E. bieneusi organisms; infecting each production animal with love E. bieneusi organisms administered in an amount sufficient for such organisms to propagate but insufficient to kill the production animal; and, during a production period following such infecting, collecting the feces of each production animal. The collected fecal material is then prepared for use.
