Abstract: Methods and systems for treatment of grain in a storage container using ozone may be used for treating grain for toxins, insects, mold, and/or odor. Downdraft methods for applying high concentrations of ozone to grain in a storage container treat grain without generating ozone-related objectionable odors or with generation of only minimal ozone-related objectionable odors. A method for downdraft ozone treatment of grain with minimal generation of ozone-related objectionable odors involves providing a negative air pressure at a bottom of a volume of grain in a storage container. A high ozone concentration is generated in air above an upper surface of the volume of grain. The ozone is drawn down into the volume of grain using the negative air pressure for a treatment time sufficient to effectively treat the grain without causing significant ozone-related commercially-objectionable foreign odors in the grain.

Abstract: A droplet forming flow cytometer system allows high speed processing without the need for high oscillator drive powers through the inclusion of an oscillator or piezoelectric crystal such as within the nozzle volume or otherwise unidirectionally coupled to the sheath fluid. The nozzle container continuously converges so as to amplify unidirectional oscillations which are transmitted as pressure waves through the nozzle volume to the nozzle exit so as to form droplets from the fluid jet. The oscillator is directionally isolated so as to avoid moving the entire nozzle container so as to create only pressure waves within the sheath fluid. A variation in substance concentration is achieved through a movable substance introduction port which is positioned within a convergence zone to vary the relative concentration of substance to sheath fluid while still maintaining optimal laminar flow conditions. This variation may be automatically controlled through a sensor and controller configuration.

Abstract: Disclosed is a method and apparatus for sampling and determining the presence of certain substances, such as residues of contaminants in containers. The method includes steps of: injecting compressed air into said containers in order to displace at least a portion of the contents thereof; evacuating a sample of the container contents so displaced by applying suction thereto; and analyzing the sample evacuated to determine the presence or absence of the certain residues therein. The compressed air is injected through a nozzle into an opening in the containers to displace a portion of the container contents and form a sample cloud outside of the container. The sample cloud is then at least partially evacuated by suction and the sample is analyzed for the presence of contaminants such as nitrogen containing compounds or hydrocarbons. The sample cloud may be split into first and second portions.

Abstract: A method of processing groups of envelopes that have contents contained therein. The method prints information on at least one side of an envelope and then separates that side from the rest of the envelope. The contents of each envelope are then placed adjacent to the separated side and assembled in series with other separated sides and contents. When the separated sides and contents are assembled, the separated sides act as a boundary between other envelopes, thus preventing the contents of the envelopes from becoming commingled with contents from other envelopes. The printed information on the separated side of the envelope provides an audit trail for subsequent processing.

Abstract: An infeed conveyor feeds seed cotton modules successively to a feeder head having disperser drums which reduce the modules to clumps of cotton. Incorporated into the conveyor are fluted rollers and beater rollers which cooperate to agitate the bottom portion of the modules and work the fibers on the bottom of each module so as to stretch and relax these fibers, thereby causing the sand, dirt, mud, trash and other debris accumulated along the bottom of the modules to be released. A conveyor feeds this debris to a hopper. Further, after the cotton modules have been dispersed into clumps of cotton by disperser drums in a feeder head and the clumps deposited in a clump chamber, a trough having a sieve means receives the clumps of cotton. In the trough, a conveyor disposed in the trough urges the clumps of cotton in a lateral direction toward an air separator box adjacent the feeder head.

Abstract: In a preferred embodiment, a sorting apparatus according to the present invention includes a conveyor belt for carrying a stream randomly-arranged articles, at least some of which are post-consumer plastic articles made of PVC and others of which are made of PET. The conveyor belt carries the articles to an irradiation area where they are irradiated with ultraviolet light that induces the post-consumer articles of PVC to emit phosphorescent light that persists after the irradiation ends. The conveyor belt then carries the articles to an inspection zone that is isolated from the ultraviolet light. A video camera is positioned to receive phosphorescent light emitted from post-consumer articles made of PVC. Other articles commonly in the stream of post-consumer plastic articles (e.g., PET) do not emit phosphorescent light and are, therefore, distinguishable from the PVC articles.
