Abstract: A process for treating a body water to purify it. In this process, a portion of the water to be treated is continuously caused to flow at a rate of at least about 60 feet per minute and is continuously agitated, aerated, and fed into a biochamber within which are disposed at least five distinct strains of microorganisms. A screen is disposed in the biochamber below the microorganisms, and air is forced through such screen during the processing of the water.

Abstract: A rotary device containing a housing with two side plates, a shaft, an eccentric connected to the shaft, a rotor mounted on the shaft, a first gear, and a second gear. The rotor contains at least 3 sides, the housing has an interior surface defined by at least a first lobe and a second lobe, the first gear is an internal gear which is connected to the rotor, the second gear is an external gear connected to the housing, the difference between the pitch diameter of the first gear and the pitch diameter of the second gear is is equal to twice said eccentricity of the eccentric, and the ratio between the pitch diameter of the first gear and the pitch diameter of the second gear is equal to the ratio between the number of said sides in said rotor divided by the number of lobes in the interior surface of said housing.

Abstract: A modified atmosphere package for storing oxygen sensitive goods which contains a a gas permeable tray for holding the oxygen sensitive goods, a gas permeable film positioned over and adjacent to the tray forming a wrapped tray, a barrier bag with an inside surface and an outside surface within which the wrapped tray is disposed, an oxygen absorber disposed within the barrier bag, and a pressure relief valve located on the outside surface of the barrier bag. The tray contains foam material, at least about 20 volume percent of which is open cell foam with an average cell diameter of from about 0.001 to about 0.020 inches. A film of gas permeable material is disposed over and contiguous with the bottom wall of the gas permeable tray. The barrier bag has an oxygen permeability of less than 10 cubic centimeters per 100 square inches per 24 hours.

Abstract: A package for storing oxygen-sensitive goods (such as meat) which contains a gas impermeable tray wrapped in a gas permeable film, a barrier bag within which the wrapped tray is disposed, a closure for closing an open end of the barrier bag, and two one-way valves. One of the one-way valves is located on the inside of one side of the barrier bag, and the other of the one-way valves is located on the outside of the other side of the barrier bag.
