Moving Flow Control Means Coordinated With Power-driven Conveyor Section Patents (Class 198/526)
  • Patent number: 8640855
    Abstract: A dust control apparatus and method for a bulk material handling transfer system having a chute comprising a pathway there through for handling varying volumes of bulk material flowing through the chute using gravity flow. A self-adjusting air restrictor gate is mounted in the chute for engaging the upper surface of flowing bulk material through the chute for restricting the air pathway during material volume flow variations to reduce dust emissions. The gate member contacts the upper surface of flowing bulk material and moves up and down in response to the flow of bulk material through the chute to restrict the flow of air to reduce dust. A counterweight mechanism and a damper helps maintain controlled contact of the air restrictor gate with the upper surface of bulk material flowing through the chute.

  • Patent number: 5494150
    Abstract: A batter board is interposed between an upper conveyor belt, that is discharging granular material, and a lower conveyor belt that is receiving it. The batter board is adapted to deflect the downwardly arching stream of material, to laterally adjust the location on the lower belt where the material is deposited. The extent of deflection practised is controlled in response to measurements which monitor the downstream belt side travel of the lower belt. The position of the batter board is adjusted with hydraulic actuators protected with a shock absorbing system.

  • Patent number: 4447382
    Abstract: An apparatus for making a foam pad for carpets has features to improve the quality of the pad. The apparatus has a hopper section for receiving foam particles coated with heat activated bonding agent. An extruder section compresses the particles as they are moved continuously along a conveyor belt. A heat section heats the particles after being compressed. A raking device in the hopper section rakes the top of the body of particles prior to entering the extruder section. The raking device rakes in a direction opposite to the movement of the body of particles. The raking device can be raised and lowered to change the level of the particles, and thus the density. The raking device also forms the top of the body of particles with upwardly tapered corners. A plate located below the hopper and extruder sections supports the lower conveyor belt. The heat section uses steam chambers with a perforated top, which also serves to support the conveyor belt.

  • Patent number: 4421226
    Abstract: Rapidly descending articles are decelerated in a segmented walled mechanism which alternately decreases in cross-sectional area to decelerate and restrain an article and subsequently increases in cross-sectional area to permit the article to fall safely to a reception device, such as a conveyor, below. The decrease in cross-sectional area is synchronized with the delivery of the article from an associated fabrication device. The mechanism also includes a synchronously oscillating receiving tube which alternately tracks one moving discharge site on the fabrication device and then returns to engage and track an adjacent discharge site. Orientation of the article is maintained as it passes through the cross-sectional area and onto the conveyor.

  • Patent number: 4271953
    Abstract: An automatic feeding hopper employs a reservoir for storing disk-like objects in a plurality of substantially horizontal rows in a substantially vertical plane. A conveyor adjoins the reservoir for engagement with a substantial portion of the lowermost row of disk-like objects in the reservoir to remove the disk-like objects from the reservoir, an exit chute is positioned adjacent the conveyor to receive the disk-like objects in a single row, and a deflecting member is positioned near the entrance to the exit chute to guide and maintain the flow of disk-like objects in a single row from the conveyor into the exit chute. The deflecting member has an upper concavely curved surface intersected by a lower curved surface which leads into a side of the exit chute, the curved surfaces meeting at an edge located a distance above the surface of the conveyor slightly more than the diameter of a disk-like object.
