Fluid Jet Patents (Class 209/644)
  • Patent number: 10343188
    Abstract: The invention is used in various branches of industry, in particular in agriculture for preparing seeds for sowing and for selection purposes. The method of separating a granular mixture in a flowing medium is based on a gravitational supply of particles, with an aerodynamic, monotonously increasing action thereon with a cascade of flat jets, said cascade being stabilized in terms of pressure and discharge. Large impurities are removed from the granular mixture beforehand, and stable parameters are maintained in the separation chamber. The device comprises a vibrating screen, an adjustable hopper with an agitator and a vibrating chute, a generator of a cascade of flat jets, which is connected to a drive for supplying air under pressure, a fraction collector and a separation chamber. The output of the separation chamber is covered with a filtering element in the form of a rotating drum with a calibrating sifter on the surface, said sifter being connected to a cyclone.

  • Publication number: 20110210047
    Abstract: An automated machine is used to handle and manipulate individual pieces of particulate matter. The particulate matter is contained in a bin. The machine operates to pick single individual pieces of the particulate matter from the bin. The picked individual pieces are then conveyed for further handling. Pneumatic transport is primarily used for the conveying operation. One aspect of the handling involves individually weighing each piece of the picked particulate matters. Another aspect of the handling involves sorting the individual pieces of particulate matter into a plurality of receptacles. Yet another aspect of the handling involves both weighing and then sorting the individual pieces of particulate matter, wherein the sorting operation may be performed based upon the measured weight of each piece.

  • Patent number: 8002117
    Abstract: A method and apparatus for sorting a gas-driven stream of generally flat and light-weight articles of varying dimensions execute a, preferably optical, inspection and upon so finding a non-conforming article remove the latter from the stream. In particular, the inspection and the sorting are executed during a substantially straight movement of the articles. The removing is executed through gas driving in a direction substantially transverse to the straight movement. Advantageously, the inspection is preceded by orienting the articles through a centrifugal force that orients said articles against an inclined wall in a transition to the vertical movement. Also airflow means (83,84) can be used to confine the articles in a thin layer.

  • Patent number: 7997413
    Abstract: In an apparatus in spinning preparation for separating foreign objects at conveying equipment for fiber material, at least one separation device is associated with the conveying equipment. The separation device comprises an arrangement for producing a blast of air that flows in the direction onto the conveying equipment and generates an air flow that detaches the foreign objects from the conveyed fibers and carries them away. The arrangement comprises a plurality of blast nozzles arranged across the width of the conveying equipment and connected to a compressed air pipe and to valves. To reduce the proportion of good fibers in the waste in a simple manner, and to allow a more selective action of the blast air current, a bar member for mounting the blast nozzles is present and the nozzles are integrated in the bar member.

  • Patent number: 7968814
    Abstract: A grain images obtained by CCD line sensors are processed by binarization processing to obtain contour images of grains and images of colored portions in the grains. The images are displayed on a monitor screen of an operating panel 30. The contour images and the images of the colored portions are displayed in a superposed state. Box frames generated by a highlight display circuit in control means 12 are simultaneously displayed by being superposed on the contour images having defective portions, thus producing a highlight display of defective grains. The defective grains include a grain having a light colored portion and a grain having a dark colored portion.

  • Patent number: 7905356
    Abstract: A method for separation of heterogeneous products included in household waste (HW) comprises separating the products in a fractionation vessel containing a liquid. The waste includes components, of which at least some are capable of floating in the liquid. The components are exposed to a first essentially horizontal force (P1) in a first direction (D1) enforced by a flow of the liquid in the fractionation vessel and to a second essentially horizontal force (P2) in a second direction (D2), which is substantially different from the first direction (D1). The combined impact of the forces (P1; P2) on the components spreads the components and leads them to at least two collection areas. Products of varying buoyancy may thus be treated separately.

    Abstract: The methods and apparatus separate fines from crushed rock and stone. A motorized conveyor belt system is activated that includes a conveyor belt moving in an upward direction. A spray system is activated to spray a fluid on an underneath surface of the conveyor belt. The mixture of rock and fines are directed to the conveyor belt. The rock tumbles or rolls down the conveyor belt and is collected at a first end of the conveyor belt. The fines stick or adhere to the conveyor belt, and the fines are scraped off of the conveyor belt at or near the second end of the conveyor belt. The apparatus includes a conveyor belt system, including a moving belt, a motor to move the belt, the belt including a first end and a second end, wherein the second end is elevated relative to the first end. The apparatus includes a spray system, including a source of fluid, a sprayer in fluidic communication with the source of the fluid, and the sprayer positioned to spray a surface of the belt with the fluid.

  • Patent number: 7740140
    Abstract: A method for sorting tablets at a rotary press for making tablets, comprising the following steps: the individual tablets are monitored with regard to at least one property of their condition during the pressing process, and a bad-signal is generated, if a tablet does not fulfill the property, and tablets which do not generate a bad-signal being good-tablets; the good-tablets are directed from a die plate of the rotary press into a good-channel; after a bad-signal has been generated, a bad-tablet is directed into a bad-channel by means of an air blast; by means of a further air stream, which is directed into the bad-channel, the bad-tablet is accelerated into the bad-channel whereby a returning to the die plate is avoided.

  • Publication number: 20100141013
    Abstract: Coal burning waste gases, notably carbon dioxide (CO2), can be removed or sequestered, and the distribution and utilization of coal as a safe, efficient, and convenient heat source can be improved. Carbon dioxide, a waste gas as from a coal burning process, can be sequestered within freshly fractured rock particles, such as Oligocene rock serpentine, using an adapted version of a rotary collider to fracture down hens-egg sized incoming rocks in a pressurized waste gas. The process sorts the small, fractured rocks and coats them after CO2 sequestration with a cementitious coating for use as a component of building material. In order to improve the transport and delivery of mined coal it is an advantage to fracture the coal and coat the particles with an aqueous liquid. The methods and apparatus deal with the improved delivery of said liquid-coated coal particles for current and new customers who become interested in using coal as an economical heating fuel.
