Abstract: A high pressure transfer device for feeding wood chips to a digster in the production of paper pulp has enhanced efficiency. A pocketed rotor is mounted for rotation in a housing having first through fourth ports, with a screen at the third port for screening wood chips out of liquid passing through that third port. This screen is blanked at the leading edge in the direction of rotation so that as a pocket rotates into operative association with the first and third ports, the pocket inlet has an arcuate extent of about two inches which is exposed to the first port --large enough to allow chips to start flowing freely into the pocket--before the outlet of that pocket is exposed to a suction source in communication with the screen.

Abstract: A device achieves the entrainment of ultralight loose fill packing materials in an air stream to transport the packing materials into a depository for reuse or disposal. The device has an elongated air flow duct, with relatively low air flow induced by a rotating fan blade that extends partially into the interior of the duct. The construction provides for the air flow into the duct to be equal to the air flow out of the duct. A screen surrounds the fan blade to prevent contact with the packing materials as they flow through the duct. The collected packing materials are deposited into a flexible plastic bag, for example, that can be releasably secured to a perforated shroud on the outlet end portion of the transport duct. This device readily removes the loose fill packing materials from shipping cartons or, in the alternative, can recover widely scattered pieces of the material.

Abstract: The present invention provides an apparatus and method for the separation of solids entrained in fluid streams. The apparatus consists of a pipecross chamber which is divided into two regions by a perforated deflector/separator plate angularly disposed within the chamber. A shear jet is disposed perpendicular to the flow path and higher pressure fluid is thereby injected into the chamber to deflect and separate entrained solids. Embodiments are disclosed in which no deflector/separator plate is disposed within the chamber, separation being effected by the shear jet alone. In preferred embodiments the apparatus and method are used to protect a centrifugal pump impeller from damage by the solids. While conventional pipe joints and parts can be used, an alternate embodiment provides removable side plates and a removable deflector/separator plate for ease of installation and maintenance. Further enhancements include pipe elbow means having a jet in the direction of fluid flow through the elbow.

Abstract: A method and system are provided for continuously conveying hard particulate material of non-uniform size, like coal. A high pressure transfer device has high and low pressure feed and discharge lines extending to and from it, and a screen arrangement for allowing liquid and fines to pass from the low pressure feed line to the low pressure discharge line, while stopping large particles. An excess accumulation of fines is prevented by providing a screen assembly vertically above the high pressure transfer device. Level control in a hopper--which provides the low pressure feed line--is accomplished merely utilizing an overflow technique. The concentration of particles in the liquid in the high pressure discharge line is maintained about 50% by withdrawing a portion of the liquid (while still under pressure) from the high pressure discharge line, and returning it to the high pressure feed line. A density measuring device downstream of the liquid withdrawal automatically controls the amount of liquid withdrawal.

Preferably the screen is associated with one of the ports of the housing and fluid injection nozzles are associated with the screen for injecting liquid under pressure toward the screen to effect dislodgement of any particles that may be lodged in the screen and thereby prevent damage to the screen. The operation of the fluid injection nozzles is timed to the rotation of the rotor.

The device includes a pocketed rotor rotatable in a housing, with a center screen mounted in each rotor. The screen is mounted within each pocket interior so that as liquid under pressure enters the pocket through its inlet the screen will move to enlarge the volume between the inlet and the screen.

Stops are provided extending from the pocket walls to prevent the screen portions for pivoting into alignment with the pocket inlet or outlet, and each pocket preferably has a substantially circular cross-sectional internal configuration.
