  • Patent number: 5666878
    Abstract: A system that sterilizes and compacts medical waste. The system includes a vessel which has a door that provides access to an inner chamber. The inner chamber is coupled to a compressor and a source of heating fluid. The vessel also has a jacket that surrounds the inner chamber. The jacket is coupled to the source of heating fluid and a source of cooling fluid. The operation of the system is controlled by a controller. To sterilize and compact medical waste, the door is initially opened and the waste is placed inside the inner chamber. The door is closed to seal the vessel. A vacuum is pulled within the inner chamber to remove any moisture contained therein. Simultaneous with the creation of the vacuum is the introduction of heating fluid to the jacket to heat the vessel. Heating fluid is then introduced to the inner chamber to sterilize the waste. After the waste is sterilized, a vacuum is pulled to remove the heating fluid from the inner chamber. The waste is then compacted by a piston.

  • Patent number: 5277109
    Abstract: This invention is particularly useful in food processing for separating crumbs and particles of breading material which have become suspended in frying oil, so that the oil may be reused. Separation is done in a unique cylinder having a hollow piston, whose forward end has a screen and whose aft face is imperforate. The cylinder has an openable door at its forward end. Near its end door the cylinder has a liquid inlet and a liquid outlet spaced somewhat aft therefrom. When the piston is in its retracted position its screen end is positioned axially between the inlet and outlet, so that the liquid may pass through the screen. Air pressure in the portion of the cylinder aft of the piston acts against its imperforate face to drive it forward. The screen end of the piston filters and drives the liquid back to the outlet, solids are compacted against the door.

  • Patent number: 4757758
    Abstract: An extrusion-type trash compactor in which the trash receiving chamber is inclined downwardly towards an outlet opening at an angle of about forty-five degrees, and the outlet opening connects with the inlet of a compacting chamber that is disposed horizontally, whereby the overall length of the compactor is reduced to adapt the compactor for use in smaller trash rooms. The angle of the ram also functions to reduce blockages in the hopper by working the bottom of the accumulated pile of trash as it's moved relative thereto - which reduces the possibility of trash backing up into the chute leading into the hopper and thus reduces damage that may be caused by fire. The compacting chamber is also pivoted to the outlet opening of the receiving chamber to permit it to be opened for the purpose of clearing jams in the compacting chamber.
