  • Patent number: 4433587
    Abstract: A sampler for dry material flowing under pressure in a flow duct including a tubular housing, mounting an air cylinder, the piston rod of which connects to a sample tube which is extendible from the housing and into the flow line, the sample tube having a plug forming an obstruction in its rear portion, the forward portion of the sample tube having a material receiving slot in one side facing upstream in the flow duct, and a bleed port on the downstream side of the sample tube adjacent the receiving slot, the sample tube having a discharge port adjacent the front face of the plug in the sample tube and aligned with an outlet opening in the tubular housing and with an outlet spout to which a sample collecting container may be attached, and a seal in the tubular housing spanning entirely across the receiving port and discharge port and the space therebetween on the sample tube and confronting the fluid pressure in the sample tube as the sample tube is withdrawn, until the discharge port opens to the outlet open

  • Patent number: 4389906
    Abstract: A sealed housing having entrance and exit ports at its upper and lower surfaces for connection into a vertically extending gravity spout, with a collecting head mounted within the housing for swinging movement across the central flow passage extending from the entrance port to the exit port. The collecting head has an elongate opening confronting the entrance port, such that particulate matter flowing through the housing will be collected within the interior of the collecting head and passed out of the housing through a discharge tube, for sampling. Rotary air cylinders disposed on top of the sealed housing adjacent the entrance port effect swinging movement of the collecting head about an axis parallel to that of the central flow passage, such that the collecting head passes entirely through the particulate flow, from one side of the product stream to the other, thereby assuring a representative sample.

  • Patent number: 4372080
    Abstract: A method of treating of peanut seeds with a fungicide effective against seed-borne pathogens consisting in treating the seeds with a suspension including oil as a base and also including active chemicals in the form of finely ground particles carried by the oil in the suspension and allowing the seeds to dry with the result that a coating including active chemicals remains on the seeds to minimize chemical dust related environmental and physical problems. The slurry contains a balance of non-phytotoxic mineral oil, water and solid materials providing the active ingredients, and emulsifiers. The seeds have a dried coating embracing and at least partially penetrating the testa of the seed and producing thorough contact with the entire periphery of the seed, the coating containing at least one fungicide effective against the seed-borne pathogens.

  • Patent number: 4079696
    Abstract: An improvement in an apparatus for treating seeds or other particles with a liquid. The apparatus includes a receiving chamber for receiving particles and liquid, and means for conveying consecutive batches of particles and liquid to the receiving chamber. Liquid is metered in batches through a liquid metering means which includes a container and a cyclic container transport. The latter is responsive to the conveyance of batches of particles to the receiving chamber and cycles the container between a dip position in a supply of treating liquid and a dumping position in which a batch of liquid is conveyed to the receiving chamber. The transport orients the container in its dip position so as to drain the container when the level of treating liquid recedes below the container. The retention of treating liquid in the container when the apparatus is not in use is thus avoided.
