Publication number: 20140030031Abstract: Rapid evacuation and deployment of dry materials is achieved by the dual structure of this device and the method of using it to fill and empty vacuum reloading tanks automatically. This permits materials such a bentonite, barite or cement to be handled easily and without dust on a rig floor and mixed appropriately as needed for well control and completion operations. Dry bulk material is offloaded from an offshore supply vessel into atmospheric tanks, which provide fluidized bed systems to aerate and agitate and move material through piping into the vacuum re-loader tanks. The dual re-loader tank system allows one tank to be emptied while another fills thereby providing sufficient flexibility to expertly manage receiving, storage, transfer, filtration and control of the bulk material on various space-critical platforms, including offshore rigs and service vessels, that require the handling of dry bulk materials in an accurate and dust-free manner.Type: ApplicationFiled: April 4, 2012Publication date: January 30, 2014Applicant: PROVEN ENGINEERING AND TECHNOLOGIES, LLC A DBA OF PROVEN TECHNOLOGIES, LLCInventors: Gary L.

Patent number: 6764296Abstract: A fluidizing method transports particulates by gravity flow but passes the particulates through a fluidizer which is partitioned by a porous distributor plate to form first and second chambers and wherein the particulate materials pass through said first chamber which is in gaseous communication with said second chamber via the porous distributor plate. Gas is delivered to the second chamber at a pressure sufficient to generate a gas bearing between the porous distributor plate and the particulate material. The gas is permitted to migrate through the particulate material, but it is then vented to the surrounding atomosphere without causing substantial turbulence in the particulate material and to reduce tendencies for dusting and separation of the particulates into sizes.Type: GrantFiled: May 21, 2002Date of Patent: July 20, 2004Assignee: MatsysInventors: Tony F. Zahrah, Rajkumar Raman, Phillip A. Parrish, Roderick Rowland

Patent number: 6485284Abstract: A gas-assisted flow and filling device for transporting particulate material and filling die cavities includes a source of low-pressure gas for delivering gas to a chamber that is separated from a fluidizing chamber by a porous distributor plate which permits the gas to flow through the particulate material and out a vent screen so that the particulate material is permitted to flow out of the fluidizing chamber essentially free of gas and wherein the pressure of the gas delivered to the fluidizing chamber is sufficient to provide a gas bearing to said particulate material adjacent the distributor plate, but not high enough to cause turbulence in said fluidizing chamber.Type: GrantFiled: October 16, 2000Date of Patent: November 26, 2002Assignee: MatsysInventors: Roderick Rowland, Tony F.

Patent number: 6283679Abstract: A seed cart for an air seeder is provided with pneumatic distribution system having a primary air distribution manifold. The primary air distribution manifold is provided with a top rank of venturis and a bottom rank of venturis for receiving an air stream from a blower which is divided into a top rank air stream and a bottom rank air stream. A selector valve is located above the top rank of venturis immediately below a product meter. The selector valve selectively directs metered product to either the top rank of venturis or the bottom rank of venturis. In a first position the selector valve directs metered product to the top rank of venturis in its second position the selector valve directs metered product to the bottom rank of venturis. Each selector valve is also provided with first and second air valves. In the selector valve's first position, the first air valve is open and directs air tapped from the top rank air stream to the product tank feeding product to the top rank of venturis.Type: GrantFiled: November 2, 2000Date of Patent: September 4, 2001Assignee: Deere & CompanyInventors: David Walter Gregor, Terry Lee Snipes, Donald Raymond Wisor

Patent number: 6079461Abstract: A method and apparatus for transferring comminuted product from an unpressurized storage unit to a tank, especially a trailer-mounted tank. According to this method, an inert gas source is provided, preferably mounted on the trailer, and a conduit is provided to carry the product, which conduit is connected between the storage unit and the tank. The tank and conduit are evacuated so as to create a pressure differential between the storage unit and the tank, and the inert gas is allowed to flow into the evacuated tank in response to the partial vacuum therein. The product is then allowed to flow through the conduit to the tank in response to the partial vacuum therein. An improved trailer for receiving comminuted product according to a practice of the method is also disclosed.Type: GrantFiled: March 2, 1999Date of Patent: June 27, 2000Assignee: The Heil Co.Inventors: Larry Nelson Fisher, Warren Peery Groseclose

Patent number: 6056483Abstract: In a powder coating material feeding apparatus, a lid section is mounted onto an opening of a metal drum containing powder coating material, and a support unit holds the metal drum in its upside-down or tilted position. An air distribution panel supplies carrier air into a conveying hose via a carrier air supply port, opens a pinch valve, activates a vibrator, and supplies fluidizing air into an air chamber in the lid section to fluidize the powder coating material in the metal drum. With this arrangement, the powder coating material is drained into the conveying hose through a drain port in the lower end of the metal drum in its upside-down position, and is then transferred to a powder tank by the carrier air.Type: GrantFiled: September 10, 1997Date of Patent: May 2, 2000Assignee: Nihon Parkerizing Co., Ltd.Inventors: Akira Nakamura, Takayuki Eto, Haruhiko Miyazaki

Patent number: 5558474Abstract: Apparatus 10 for discharging particulate material such as sand has a container 11 for the material, a supply conduit 20 for pressure gas, e.g. air, connected to an inlet 16 and via pipe 17 to an outlet 12 and a flexible discharge conduit 14 leading to nozzle 15. Flow in conduit 20 is controlled by a manually operable valve 21 biassed closed and when open gas and particulate material flow forcefully through nozzle 15. All the gas goes through valve 21. The apparatus can thus be controlled by an operative remote from the container 11 without consumption of pressure gas when valve 21 is closed. The valve 21 is mounted for convenient operation by a user. In a modification the valve 21 is nearer the container and operated from near the nozzle through a mechanical connection.Type: GrantFiled: March 28, 1994Date of Patent: September 24, 1996Inventor: Kevin Wildon

Patent number: 5156499Abstract: An air lock for injecting a fibrous or granular material, such as insulation, into an airstream. The air lock has two counter-rotating, generally cylindrical rollers in facing contact with each other along their edges, made of a resilient material such as a closed cell foam. The rollers are also in facing contact with the outside of a tube or cylinder through which the airstream flows. The insulation is positioned on top of the rollers, and the rollers feed the insulation between them and into the airstream. The contact between the rollers and between the rollers and the injection tube create the air lock between the airstream and the atmosphere. The invention can also be used in a vacuum machine, particularly suited for vacuuming and collecting fibrous or granular materials.Type: GrantFiled: March 19, 1991Date of Patent: October 20, 1992Inventor: Henry A.
