Applying Solid Particulate Material Patents (Class 118/308)
  • Patent number: 10569479
    Abstract: Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles. Also described are systems for performing the various processes.

    Abstract: A method and apparatus for applying or dropping granules onto the asphalt coated surface of a moving sheet in shingle manufacturing is disclosed. The method includes sharing each drop between two or more blend rolls with a subsequent blend roll or rolls applying a partial drop directly on top of partial drops already applied by a first blend roll or rolls. High production speeds can be accommodated since each roll can be operated at slower rotation rates and with slower acceleration and deceleration requirements than would be required if the full granule drop were applied during the same time interval with a single blend roll.

The recoater comprises a bridge, two supports, one at either end of the bridge, a powder reservoir, and a substantially rectangular plate which extends between the two supports and contains an opening through which the powder reservoir either extends into or through or through which build powder can be fed into the powder reservoir. The plate has a length to minimum width ratio of no more than about 7.0 and a length to maximum width ratio of no more than about 5.0, the plate being adapted to brace the bridge into a perpendicular relationship with the first and second supports when the recoater is being controllably moved and the powder reservoir is dispensing powder to form a powder layer.

  • Patent number: 9120269
    Abstract: A device and a method are described for feeding a material layer onto a construction platform, or onto at least one material layer located on the construction platform, for producing an object, which is mounted to linearly move relative to a material reservoir and the construction platform along a motion plane. A circulating band is stretched around at least two molded bodies and contacts the molded bodies at least in segments. A drive circulates the band around the at least two bodies. The band has a band segment which can be fixedly in position relative to at least one body in the longitudinal section around the at least two molded bodies. At least the segments contact the material stored in the material reservoir during the linear motion from the material reservoir to the construction platform so that at least a part of the material is stripped off from the material reservoir and is applied as the material layer to the construction platform to compress the material layer.

  • Patent number: 9032902
    Abstract: A manufacturing apparatus for activated carbon filters has a non-woven cloth machine, a rolling module, a sprayer and a hot-pressing cylinder. The non-woven cloth machine is used to manufacture a body of non-woven cloth and has a processing segment. The rolling module is mounted at the processing segment to heat and melt the body of non-woven cloth. The sprayer is mounted above the rolling module to spray activated carbon powder on the body of non-woven cloth. The hot-pressing cylinder is mounted at the processing segment to heat and press the activated carbon powder with the body of non-woven cloth. The activated carbon powder can be securely attached to the body of non-woven cloth by the manufacturing apparatus to provide a preferred quality of the activated carbon filters and to reduce the cost of manufacturing the activated carbon filters.

  • Patent number: 9027506
    Abstract: A dense phase powder coating system includes a powder supply, dense phase pump, a spray gun and a diverter valve that can be used to select between conveying powder to the spray gun or circulating the powder back to the powder supply. The diverter valve may include two pneumatically actuate valve members. In one embodiment, the powder spray gun applies powder coating material to inside surfaces of a tubular container. A spray nozzle concept also is presented having a nozzle body with a conical deflector. The spray nozzle provides an uninterrupted flow between spray nozzle outlet holes and a deflector surface. The deflector may be integrally machined with the nozzle body to provide a one piece spray nozzle.

  • Publication number: 20150114288
    Abstract: A charged powder supply device is disclosed. A plurality of charged powder particles are disposed on an upper side of a carrier and at least an action source is positioned at a lower side of the carrier for acting on the carrier so as to vibrate the charged powder particles on the upper side of the carrier. As such, the vibrated charged powder particles are attached to objects to be coated, such as LEDs, under the effect of an electric field so as to form a powder layer, such as a phosphor layer. Since there are no other external forces that affect the moving direction of the charged powder particles, the powder layer can be uniformly formed on the objects.
