    Abstract: 1,223,243. Pneumatic conveyers. LA SOUDURE ELECTRIQUE AUTOGENE, PROCEDES ARCOS, S.A. 1 Oct., 1969 [15 Oct., 1968], No. 48294/69. Heading B8A. A device for feeding a non-flowing powder from a rotatable container 32 into a pneumatic conveying line 56 comprises a rotatable disc 20 extending into powder in the container and having holes 46 therein distributed around and spaced from its circumference, the powder entering the holes from both sides of the disc, and rubber faced shear plates 40, 41 on opposite sides of the disc for removing excess powder therefrom prior to the sequential co-operation of the holes 46 with both the discharge line 56 and a gas pressure supply line 57, whereby the powder is conveyed away. The disc 20 may rotate about a horizontal axis but is preferably rotatable about an inclined axis whereby due to the rotation of the container 32, powder is assisted into the holes 46 from one side of the disc as the hole moves into the powder and from the other side as the hole moves out of the powder, a pair of ploughs 38 also assisting powder into the holes. Further holes 48 in the disc tend to relieve pressure build up in the powder. The circumferential spacing between the holes 46 is less than their diameter whereby there is always a part of a hole 46 in communication with the discharge line 56. The whole device is mounted in a gas tight enclosure Fig. 6 (not shown) comprising a lower portion housing the feeding device and its drive, and an upper portion formed as an air-lock and housing an apparatus for filling the container. The latter apparatus comprises a powder holding drum rotatable in steps about a vertical axis, and at each step a plunger displaces a plug of powder through an aperture in the drum base into the container in the lower portion, the plunger sealing the passage between upper and lower portions when the drum is being refilled. A plough in the drum distributes the powder once a plug thereof has been dispensed.

    Abstract: In one embodiment, material metered by a conveyor 10 into the upper portion of hose 16 is dropped periodically into a T-cup 26 and blown by a nozzle 32 to a second stage, and a floating clamp 18 clamps the hose while the previous material is blown out of the T-cup. In an alternate embodiment, material is metered by a conveyor 110 into a charging tube 116, and, after a cap 122 has sealed the charging tube, air is blown through the charging tube to blow out the material.

    Abstract: A device for high concentrate pneumatic conveying of a granular material comprising a vessel containing the material, a conveyor duct having its lower end placed in the material within the vessel and a material discharge portion at the other end thereof, an air inlet provided in a lower portion of the vessel for introducing air into a layer of the material within the vessel, and oscillating means for giving the material at the bottom of the vessel an upward and downward reciprocal motion.

    Abstract: A method of piping cohesive particulate materials, to a delivery point, via a delivery pipe, from a mass flow hopper, the exit from which is too small for the hopper to empty by gravity alone, which comprises introducing gas under pressure into the space above the material in the hopper, introducing gas to the hopper at a point near but somewhat above the exit orifice in quantity insufficient to aerate the particulate material beyond the dense phase (i.e. not less than about 250:1 solid: gas mass ratio) and intermittently introducing gas into the delivery pipe at a point near to but somewhat beyond the junction of that pipe with the hopper exit orifice, to divide the particulate material in the pipe into discrete plugs. Apparatus for the method may have an electrical oscillator for controlling the intermittent gas introduction into a jacket surrounding a short porous section of the pipe wall.
