  • Patent number: 8282838
    Abstract: A method and apparatus is provided for removing fluids, particularly entrained and/or adherent fluids, from drill cuttings created during the well drilling process. An apron assembly collects drill cuttings and deposits such cuttings on a central rotor having multiple distinct chambers. A first chamber is loaded with drill cuttings. The central rotor thereafter cycles to a second position wherein a pressure seal is formed around the loaded first chamber. An air knife or similar device is used to blast compressed gas at the cuttings in the sealed chamber and force the cuttings against a screen. Solid components of the cuttings remain in the sealed chamber, while liquid components pass through the screen and are collected using an auger assembly. Following such separation, the rotor is cycled again, allowing dried cuttings to empty from the first chamber. The process is repeated for each chamber of the rotor.

  • Patent number: 7917018
    Abstract: Disclosed herein are wearable devices for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human, to avoid the need to apply such chemicals directly to clothing or to human's skin. The devices have an on/off switch that automatically controls a shutter which enables and restricts air flow, while also controlling fan operation and covering of a use-up cue. The device also is designed to prevent fan operation when an impregnated slab is not present. Also disclosed are preferred refills for use with such devices.

  • Patent number: 7069668
    Abstract: A transportable portable tank for storing, transporting and drying a hygroscopic material and a transportable portable tank assembly. The portable tank comprises an upper, a middle and a lower region. The upper region comprises a materials inlet, a gas inlet and a gas outlet. The middle region comprises a gas disperser. The lower region comprises a materials discharge outlet. The portable tank has a capability to effectively remove and/or exclude moisture and a capability to effectively break up agglomerates of caked hygroscopic material, such as iodine. The present invention further provides a process for drying a hygroscopic material such as iodine within a portable tank.

  • Patent number: 6978555
    Abstract: A conveyor of leaves and other products on a belt for laying the same products as a single layer, includes at least a perforated collection belt, at least a suction hood having a surface provided with holes for passage of air flow, an air suction device coupled to the hood, and dragging elements for the collection belt. The collection belt slides by the dragging elements along the perforated surface of the suction hood. The suction device generates an air flow both through the holes of the surface of the suction hood, and through the holes of the collection belt, allowing the coupling on the collection belt of a single layer of the leaves and other products due to their passage close to the collection belt.

  • Publication number: 20040098877
    Abstract: A continuous gravity flow apparatus for heating and/or drying of particulate material is vertically disposed and is provided with an inlet at the top and an outlet at the bottom. The apparatus includes a flow passage for the particulate material which is defined between an outer housing and an inner housing. Each of the outer and inner housing defines perforated wall sections allowing for the flow of hot gas through the wall of one housing, into contact with the particulate material, and then out through the wall of the other housing. Manifolds are associated with the outer and inner housings to provide for uniform flow of the gas through the material. The perforated wall sections are positioned and designed to enhance particle-to-particle movement of the material to thereby avoid particle sticking and bridging problems.

  • Patent number: 6444038
    Abstract: A dual chambered bubbler vessel for use with solid organometallic source material for chemical vapor phase deposition systems, and a method for transporting a carrier gas saturated with source material for delivery into such systems. The bubbler vessel is designed so that carrier gas enters through an inlet in the top thereof into an inlet chamber and after it has been saturated with the organometallic vapors exits through a first porous frit located in the floor of the inlet chamber into an outlet chamber and is withdrawn from the bubbler after passing through a second porous frit element located at the outlet of the bubbler.

  • Patent number: 5647142
    Abstract: In an apparatus for drying a moist material in a stream of drying gas the residence time is increased by inserting one or more perforated plates, above which fluidized particle layers are created, and through which a portion of the drying gas and material to be dried are passed, whereas the remaining part of the drying gas and material is by-passed said perforated plates. Improved drying capacity, heat economy and operational flexibility and decreased risk for heat damage of the material to be dried are obtained.

  • Patent number: 5603169
    Abstract: A bubbler for solid metal-organic precursors is described. The bubbler includes a bubbler body, a carrier gas feed tube, an exhaust tube, a compressing plate and a pair of porous thin plates. A carrier gas is fed into a mass of metal-organic precursors through a feed tube which is connected with the bottom of the bubbler body. The exhaust tube is set away from the mass of metal-organic precursors and drains the carrier gas passing through the precursors. The compressing plate has many holes and is movable up and down along the wall of the bubbler body so that it may be positioned according to the amount of the precursors. The upper porous thin plate is located between the exhaust tube and the compressing plate, and the lower porous thin plate is located above the leading end of the feed tube, giving support to the mass of the metal-organic precursors. That is, the precursors are placed on the lower porous thin plate and there is a room between the lower porous thin plate and the bottom of the bubbler body.
