  • Patent number: 9808020
    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.

  • Patent number: 6133044
    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.

  • Patent number: 5550058
    Abstract: This invention relates to a method and apparatus for flexibly controlling sorting decisions for a flow cytometer or similar instrument at a purity vs. yield ratio of sorted particles, particularly at high event rates. The system monitors distances between sequential objects to determine if they are in close enough proximity to be within a single resolution unit of the sorting device. The "friend" or "foe" status of neighboring events is considered by this system in dealing with detected "coincident" events. The system operates on information of the desirability to sort the object, i.e. droplet, based upon the properties of the individual object. A storage and retrieval method is provided for making the information available at the time a sort operation based on a sorting logic condition is performed. Accordingly, an easily reconfigurable mode of operation control is provided to allow customized sorting strategies, based on the needs of individual applications or experiments.

  • Patent number: 5483469
    Abstract: A flow cytometer utilizes multiple lasers for excitation and respective fluorescence of identified dyes bonded to specific cells or events to identify and verify multiple events to be sorted from a sheath flow and droplet stream. Once identified, verified and timed in the sheath flow, each event is independently tagged upon separation from the flow by an electrical charge of +60, +120, or +180 volts and passed through oppositely charged deflection plates with ground planes to yield a focused six way deflection of at least six events in a narrow plane.

  • Patent number: 5472882
    Abstract: Disclosed is an improved method and system for injecting liquid into containers and for inspecting containers for the presence of certain substances such as potential contaminants such as ammonium salts or amine salts in glass or plastic bottles. A high speed system and method are provided for detecting these contaminants in these bottles. Ammonia and amines can be detected by chemiluminescence of samples of volatiles emitted from the bottles during the high speed inspection process. A solution of Na.sub.2 CO.sub.3 is injected into the bottles in order to enhance the conversion of ammonium or amine salts to free ammonia or amines which are then released as vapors. This enhances the likelihood that a gas-phase detection system such as one using chemiluminescence detection techniques will detect the presence of contaminants containing ammonium salts or amine salts.

  • Patent number: 5419438
    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.
