  • Patent number: 5096337
    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.

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.

  • Patent number: 4245935
    Abstract: An apparatus for controlling vehicles which are moved through a conduit by air and includes a processing system positioned in the conduit for collecting, storage and dispatching the vehicles in which an air pump is positioned in parallel with the processing system having its suction connected to the conduit upstream of the system and its discharge connected to the conduit downstream of the system. Valve means are connected to the conduit for reducing the tendency of the vehicles in the processing system to move upstream towards the pump suction. The valve means alternates the pressure in a portion of the processing system between less than atmospheric and at least atmospheric. One form of the valve means may include an air blocking vehicle stop movable into and out of the conduit and a valve connected between the conduit and the atmosphere upstream of the vehicle stop which is open and closed in synchronism with the vehicle stop.

  • Patent number: 4240768
    Abstract: A pump which generates pressurized air flow in a pipeline to sweep wheeled vehicles along with the air flow is provided with a flow control mechanism. First and second blocking valves which normally prevent reverse flow of air in the pipeline but which can alternately swing open to allow a vehicle to pass are automatically moved between open and closed positions by altering the pressure differential acting on the valves. The valves are urged to the open position and air flow control mechanism associated with the pump alternately directs air against the back of the valves in response to the position of a vehicle to sequentially operate the valves to move the vehicle through the pump.

  • Patent number: 4234271
    Abstract: A pipeline capsule transportation system and apparatus for transporting a continuous link of capsules, comprising a first elongated pipeline and a second elongated pipeline along which continuous links of capsules are to be transported, a loading station for loading capsules, and an unloading station for unloading capsules, the loading station comprising at least one handling zone, an inclined discharge conduit for displacing capsules from the handling zone to the first pipeline, a capsule coupler for coupling capsules entering the first pipeline to a trailing end of a continuous link of capsules moving along the first pipeline during use, decoupling apparatus for decoupling trains of capsules from a leading end of a continuous link of capsules moving in the second pipeline, a downhill station entrance ramp for diverting decoupled capsules to the handling zone, and a brake for bringing trains of capsules to rest in the handling zone.

  • Patent number: 4207018
    Abstract: A pressurizing station (1) for a pipeline conveyor (2) includes a transfer conduit (5) for the passage of load-carrying capsules (3) between upstream and downstream portions (4 and 6) of the pipeline (4, 5 and 6) and a reverse, by-pass conduit (20) extending between outlet and inlet conduits (9 and 10) respectively connected to upstream and downstream ends (7 and 8) of the transfer conduit (5). A fan (36) is provided between the outlet and inlet conduits (9 and 10). A valve member (17) is mounted on an axis extending transversely of the transfer conduit (5) and is movable, in response to fluid flow through the pressurizing station (1), between a closed position, in which first and second opposite ends (21 and 22) of the valve member (17) respectively extend across the transfer conduit (5) and across the reverse, by-pass conduit (20), and an open position in which the first end (21) of the valve member (17) is clear of the path of capsules (3) travelling through the transfer conduit (5).

  • Patent number: 4187043
    Abstract: A method and apparatus to boost the fluid pressure of a solids-transporting liquid in a pipeline, without applying any forces directly to the solid particles. A method and apparatus are shown to remove the solids from the liquid, boost the pressure of the strained liquid, and then to re-inject the solids into the liquid at its higher pressure, all without damaging even fragile solids.
