Publication number: 20080107412Abstract: A portable camera support, combining a mounting bracket or tray with a shaft or pole and a foot bar, may provide stable, portable support for cameras or other devices. The stability of the support may yield more reliable scouting results. The portability of the support may afford greater efficiency, possibly resulting in reduced time associated with locating wildlife or other items of interest. An exemplary camera support may have a mounting bracket or tray releasibly mounted to a shaft by means of a set screw threaded through a collar on the bracket. The shaft may be inserted, using the foot bar for example, into soil or other supportive media. The mounting bracket may be adjusted vertically or rotationally 360° with the aid of the set screw. The camera support may be configured with multiple brackets mounted to a shaft, thereby providing different fields of view without adjusting the brackets.Type: ApplicationFiled: May 30, 2007Publication date: May 8, 2008Applicant: Cross Winds Concepts, LLCInventors: Darrin Moore, John Buchanan, Edward J.

Publication number: 20070185362Abstract: The present invention relates to a method for preparing olefin comonomers from ethylene. The comonomer generated can be used in a subsequent process, such as a polyethylene polymerization reactor. The comonomer generated can be transported, optionally without isolation or storage, to a polyethylene polymerization reactor. One method includes the steps of: feeding ethylene and a catalyst in a solvent/diluent to one or more comonomer synthesis reactors; reacting the ethylene and the catalyst under reaction conditions sufficient to produce an effluent comprising a desired comonomer; forming a gas stream comprising unreacted ethylene, and a liquid/bottoms stream comprising the comonomer, optionally by passing the effluent to one or more downstream gas/liquid phase separators; and purifying at least a portion of said liquid/bottoms stream by removing at least one of solid polymer, catalyst, and undesirable olefins therefrom.Type: ApplicationFiled: January 17, 2007Publication date: August 9, 2007Inventors: James Lattner, John Walzer, Krishnan Sankaranarayanan, John Buchanan, Milind Ajinkya, Stephen Wood, Anastasios Skoulidas, Jay Reimers, Timothy Shaffer

Publication number: 20070185358Abstract: The present invention relates to a method for preparing linear alpha olefin comonomers, such as 1-butene, 1-hexene or 1-octene, from ethylene monomer. The comonomer generated is stored on site for use in a subsequent process, such as a polyethylene polymerization reactor. The method includes the steps of feeding an ethylene monomer, and a catalyst in a solvent to one or more comonomer synthesis reactors; reacting the ethylene monomer and the catalyst in solvent under reaction conditions to produce an effluent stream comprising unreacted ethylene monomer, a catalyst in a solvent, and comonomer; passing the effluent stream to one or more downstream gas/liquid phase separators to form a gas stream of unreacted ethylene monomer, and a liquid stream of comonomer, and catalyst in a solvent; recycling to the one or more comonomer synthesis reactors the unreacted ethylene monomer and a portion of the liquid stream; and storing a remaining portion of said liquid stream for subsequent processing of the comonomer.Type: ApplicationFiled: February 3, 2006Publication date: August 9, 2007Inventors: John Buchanan, Krishnan Sankaranarayanan, Milind Ajinkya, Stephen Wood, Anastasios Skoulidas

Patent number: 7235182Abstract: The invention provides a flotation device including a thickening tank (1) having right cylindrical sidewalls and a downwardly sloping frusto-conical floor. A drive shaft (2) is centrally rotatably mounted within the tank. Each one of a plurality of rake arms (3) is fixedly connected to the drive shaft and extends radially outwardly, substantially parallel to the tank floor. Each arm supports an array of blades (4) extending axially into the tank. An array of baffles in the form of rectilinear baffle plates (5), fixed relative to the tank, extends axially into the tank in complementary alternate radially spaced relationship with the blades (4). The baffle plates are located within the swept volume of the blades to retard fluid rotation in response to the rotation of the rake. A diametrical service bridge (6) is fixedly connected to the tank for mounting the baffle plates.Type: GrantFiled: March 11, 2003Date of Patent: June 26, 2007Assignee: OUTOTEC OYJInventors: David John Buchanan Taylor, Jeffrey Victor Belke

Publication number: 20070023937Abstract: A multi-tray distillation unit having a separator for de-entraining liquid particles. The separator comprises vertically spaced tiers of elongated, substantially horizontal open-topped liquid collector channels arrayed in parallel rows transversely to the flow of the gas. The liquid collector channels are vertically staggered to deflect the gas flow from a lower tier level through the gaps between the collection channels of an upper tier and around the channels so as to cause the entrained liquid particles to separate from the gaseous stream by inertia into the channels of the lower tier. An improved channel configuration has a rigidly-mounted, horizontally-elongated flow deflector extending downwards from an upper tier channel toward a lower tier channel, this provides gas flow deflection and increased efficiency of liquid particle de-entrainment.Type: ApplicationFiled: October 6, 2006Publication date: February 1, 2007Applicant: ExxonMobil Research and Engineering CompanyInventor: John Buchanan
