Abstract:
A plenum of distributing a flow of air from an air source includes ports extending from a face element of a body. The ports are configured to direct the flow of air out of the plenum, and the ports are arranged on the face element in a first row having first length, a second row having a second length, and a third row having a third length. The first row is positioned proximate to the top element, the third row is positioned proximate to the bottom element, and the second row is positioned between the first row and the third row. In addition, the second length is greater than the first length and the third length, and a shape of the face element is configured to accommodate the first length of the first row, the second length of the second row, and the third length of the third row.
Abstract:
A system protects an outlet of a pneumatic conveyor. The outlet has a horizontal section. The system comprises a deflector for protecting the horizontal section, and sets of stanchions therefor respectively attached to clamp assemblies mounted on the horizontal section. The deflector comprises angled walls, a plurality of crossbeams interconnecting the angled walls for reinforcing the deflector, and an end flange. Each stanchion has a foot. Each clamp assembly comprises two equal halves, fasteners joining together the equal halves, and a flange for each equal half perpendicular thereto. The system further comprises fasteners each attaching one foot to one flange, respectively.

Abstract:
Apparatus has a vacuum pump for conveying granular plastic resin material from a supply to receivers retaining and dispensing the resin when needed by a process machine with a flow limiter connected to the suction head of the vacuum pump, and a second flow limiter controlling and limiting to a maximum value vacuum flow through a conduit carrying auxiliary additives to the receivers.
Abstract:
One embodiment describes a seed planting system that includes a seed storage tank to store seeds; a seed meter fluidly coupled to the seed storage tank via a flow path, in which the seed meter receives seeds from the seed storage tank and distributes the seeds to ground engaging opener assemblies; and a seed deflector coupled to the seed storage tank directly above the flow path, in which the seed deflector guides the seeds from the seed storage tank into the flow path at an angle relative to a vertical axis of the flow path.
Abstract:
Methods and devices are provided for transfer of particulate material, such as biomass feedstocks, into and out of pressurized reactors. Improved sluice devices have an L-shaped sluice chamber having an upper, vertical component in communication with a horizontal loading chamber and a lower component in communication with a vertical reactor inlet or outlet. Piston valves seal the sluice inlet and outlet by axial displacement across the vertical component of the sluice chamber and across the vertical reactor inlet or outlet. Relative to other methods for reactor unloading, these devices consume less steam and significantly reduce furfural content of unloaded, pretreated biomass. An optional hybrid plug/sluice method of biomass feeding using the devices permits biomass loading at sluice pressures intermediate between atmospheric and reactor pressure, thereby reducing “pump cycle” time and increasing biomass throughput capacity.
Abstract:
Described is a process for conveying a powdered material from a storage bin to a delivery destination. The process utilizes an air permeation system within a hopper to facilitate the flow of material. Intermittent blasts of high pressure air are used to clean the air permeation nozzles. After the material flows from the hopper, a screw feeder with a variable speed motor is utilized for processing the material. The powdered material is then guided to a flow measurement instrument which measures the flow of the material through the process. The variable speed motor is responsive to the measurements made by the flow measurement instrument. The material is then transferred into a powdered material feeder where it is pulled through the feeder with gravity and negative pressure. The powdered material feeder then moves the material into a rotary airlock where it is deposited into a pneumatic convey airline.
Abstract:
A disk drive handling apparatus includes a manifold, one or more vacuum suction elements in fluid communication with the manifold, and one or more tips. Each tip is coupled to an end of a corresponding one of the vacuum suction elements. Each tip is compliant in one or more axes of motion.
Abstract:
A device for distributing pulverulent solids in suspension in a gas, for the purpose of depositing a coating, notably by pyrolysis, on a moving substrate (1), includes a distribution nozzle (24), the walls of which define a cavity (11) which terminates in a longitudinal distribution slit (13) and a principal powder feed duct (6) equipped with a distribution portion (7). A plurality of secondary powder feed ducts (8), connected to this principal duct by the distribution portion, enables the cavity (11) of the nozzle (24) to be supplied with powder over its entire length. At least a portion of the secondary ducts (8) is equipped with at least one pneumatic device adapted for modulating the flow rate of the powder-gas suspension which each of the secondary ducts concerned is intended for carrying.
Abstract:
Method and system unloads dry bulk materials from a tank hopper supported on a trailer, the trailer being connected to a tractor. A material conveying conduit is adapted for receiving material from the hopper. A blower is provided for supplying pressurized air to the hopper and to the conduit so that a pressure differential is created between the hopper and the conduit to thereby induce the flow of the materials from the hopper to the conduit. The pressurized air is cooled via a radiator which transfers heat from the pressurized air to ambient air. Ambient air is caused to flow across the radiator by a fan that is pneumatically driven by an air brake system located on the tractor.
