  • Patent number: 9156612
    Abstract: Method for handling material in a pneumatic materials handling system, in which material, such as waste material, is input from an input aperture of an input point, such as from an input aperture of a refuse chute or of some other input point, and is handled with a shaping device, arranged in connection with the input point or in the proximity of it, to be more compact and is transferred onwards. The shaping device is a rotary shaper, which includes rotatable handling device, which includes an aperture, which is arranged eccentrically with respect to the axis of rotation, and which rotary shaper includes at least one stationary handling device, in which case the material to be handled is conducted into the rotary shaper and/or through it at least partly by means of gravity and/or suction and/or a pressure difference.

  • Patent number: 7411130
    Abstract: The invention is a conveying wire (2) with disc-shaped conveying members (8) for use in endless tube conveyor systems. The wire (3) consists of a number of twisted strands (4) that each are made of thin threads or fibers, and including an outer jacket (6) to which the conveying members (8) are fastened directly by injection molding, where the outer jacket (6) consists of a polymer with a melting temperature which is lower than the melting temperature of the plastic material from which the conveying members are injection molded. The wire (3) is, for example, made as a balanced (torsionally neutral) wire consisting of at least three strands that each are made of very thin synthetic fibers which are individually surface treated with a polymer, providing great bending wearability to the fibers and good adhesion to the outer jacket (6) which consists of a polymer.

  • Patent number: 5209609
    Abstract: A pneumatic tube conveyor station comprises a housing connected to a pneuic conveyor tube. A tube section is arranged displaceably within the housing. For dispatching or receiving conveying cases, the tube section can be brought into alignment with, and connected to, the conveyor tube in a pressure-tight relationship. For loading or unloading conveying cases, the tube section can be brought into a position axially spaced from the conveyor tube. The conveying cases can be displaced within the station between a receive/dispatch position where they are arranged coaxially with the conveyor tube, and a load/unload position where they are arranged parallel to the conveyor tube but distant therefrom. The tube section is displaced in an axial direction by a distance greater than the length (L) of one conveying case. An axial stop is provided for stopping arriving conveying cases in the receive/dispatch position.

  • Patent number: 4859121
    Abstract: Method and device for suspending an ultrafine powder in a gas wherein a mass of powder to be dispersed in enclosing in a container between an axially movable piston and an axially fixed member adjacent to the ends of the container. The fixed member defines an inner counteracting surface facing the powder to be dispersed and has a peripheral gas inlet passage adjacent to the wall of the container and an axial passage extending out of a first end of the container. The second end of the container has a gas inlet. A first gas flow is injected into the second end of the container to move the piston towards the fixed member, thereby pressing the powder against the counteracting surface of the fixed member. A second gas flows into the first end of the container through the peripheral passage for eroding the powder adjacent to the counteracting surface and driving the eroded powder through the axial passage out of the container.

  • Patent number: 4666347
    Abstract: Solids particles are conveyed hydraulically by first mixing the solids particles with a liquid in order to form a viscous material of substantially uniform consistency. This viscous material is then introduced or injected into a flowing hydraulic medium that had been substantially free of solids prior to this viscous material injection in order to form a hydraulically conveyed flow. Variations in conduit cross-section at or near the location of viscous material injection may be provided in order to enhance turbulance and suspension of solids within the hydraulically conveyed flow.

  • Patent number: 4363573
    Abstract: An apparatus for feeding articles with a head and a shank such as screws one at a time to a tool such as a power screwdriver through a hose. The apparatus has a pilot passageway into which articles are transferred one at a time by a metering arm driven by a fluid motor. Preferably, upon transfer, each article is instantaneously propelled through and discharged from the pilot passageway by a stream of compressed air discharged into the pilot passageway downstream of the inlet through which articles are transferred into the pilot passageway. Each article is propelled through the pilot passageway initially by aspiration and, subsequently, by the stream of compressed air impinging on the article. Alternatively, each article falls due to gravity through the pilot passageway and a portion of the hose and is then propelled through the hose by a stream of compressed air.

  • Patent number: 4189260
    Abstract: A dispatch and receive terminal that, in preferred form, includes an air tight pusher housing and a pusher flap swingably mounted to move between a retract position and an extend position in response to air pressure in that housing. In the dispatch or pressure mode, the pusher flap swings into an air tight terminal housing to push the carrier axially along the guide tray and partially back into the system tube. After the carrier has been initially dispatched back into the system tube, and as the pusher flap swings further into the terminal housing to an open position, the pusher flap structure opens a pressure port between the terminal and the pusher housings, thereby pressurizing the terminal housing and the system tube behind the carrier for pushing the carrier completely out of the housing and at least partially through the tube.

  • Patent number: 4174868
    Abstract: The present invention provides apparatus which is adapted to be connected to a source of compressed air for pneumatically applying material to an object. The apparatus includes a main conduit having one end connected to the source of compressed air, and having an opposite discharge end; a tubular wall having open ends and adapted to contain a quantity of material therewithin; and a piston slidably mounted within the tubular wall. A supply conduit communicates one end of the tubular wall with the main conduit. A pressurizing conduit is arranged to cause pneumatic pressure to be selectively applied to the piston to extrude material through the supply conduit into the main conduit. Such extruded material is propelled along the main conduit by a continuous flow of compressed air therethrough, and is ultimately discharged on to the object.
