Patent number: 8011514Abstract: Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to facilitate the removal of solid particulates, as well as the removal of metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.Type: GrantFiled: June 29, 2007Date of Patent: September 6, 2011Assignee: Georgia-Pacific Chemicals LLCInventors: James T. Wright, Carl R. White, Kurt Gabrielson, John B. Hines, Lisa M. Arthur, Michael J. Cousin

Publication number: 20100294725Abstract: The present invention relates to polysaccharides that have been modified by providing azetidinium functionality thereto. Such functionality can be provided by crosslinking a polysaccharide with a resin having azetidinium functional groups. In one or more aspects, the polysaccharide can comprise one or more of starch, guar gum, alginate or derivatives thereof. Polysaccharides having azetidinium functionality according to the present invention are suitable for multiple uses. Such uses include, but are not limited to, removal of one or more solid materials from a liquid, beneficiation of an ore, removal of metallic ions from a liquid; providing oil from bitumen; and removal of mercury from synthetic gypsum. Other uses of the functionalized polysaccharides of the present invention include hydroseeding, dust control and corosion control.Type: ApplicationFiled: October 17, 2008Publication date: November 25, 2010Applicant: GEORGIA-PACIFIC CHEMICALS LLCInventors: Michael J.

Patent number: 6706809Abstract: Infinitely water soluble, storage stable, low molecular weight, amine-modified resins/binders (e.g., phenol-formaldehyde resole resins and binders made therefrom) are used to produce low odor fiberglass products, such as fiberglass insulation for automobile headliners and room dividers. The cured, bonded fiberglass products have low TMA (trimethylamine) emission because the free formaldehyde in the resin has been scavenged with melamine, which resists thermal decomposition, and because the binder contains a relatively low urea content, which is a TMA contributor. The resole resin production process includes adding two different formaldehyde scavengers (e.g., melamine and urea) to produce a modified phenol-formaldehyde resole resin. This resole resin is produced into a binder by mixing with water, optionally in the presence of a latent acid catalyst (e.g., an ammonium salt of a strong acid).Type: GrantFiled: November 21, 2001Date of Patent: March 16, 2004Assignee: Georgia-Pacific Resins, Inc.Inventors: Kim Tutin, W. Hayes Ingram, Mary L. Epling, Kurt D. Gabrielson, James T. Wright, Carl R. White

Patent number: 6039268Abstract: An arc marking system is provided for a sprinkler that waters an arc, either a full circle arc or a part circle arc. The system includes a plurality of arc indicators provided on the top of the nozzle assembly. Each arc indicator is adjacent an arc indicia such that each arc indicator represents a different arc that this sprinkler is capable of watering. After ascertaining the arc that a particular sprinkler can water, the arc information can be marked on the nozzle assembly by cutting off the arc indicator that is adjacent the numeral that represents the number of degrees covered by the arc. Thus, the arc information is added to the top of the sprinkler where it can be easily seen.Type: GrantFiled: May 22, 1998Date of Patent: March 21, 2000Assignee: The Toro CompanyInventors: Michael J. Grundy, James T. Wright

Patent number: 5853026Abstract: A valve for controlling the flow of a liquid includes a valve seat which is engaged by a selectively operable valve member. A pressure chamber above the valve member contains upstream pressurized fluid in the closed position of the valve. The valve is opened by bleeding off pressurized fluid from this pressure chamber. A manual bleed screw assembly is used to manually open the valve when desired by initiating this pressure bleed procedure from the pressure chamber. The bleed screw assembly bleeds the pressurized fluid to a downstream location in the flow path, rather than to atmosphere, without having to completely remove the bleed screw assembly from the port in which it is received.Type: GrantFiled: August 30, 1994Date of Patent: December 29, 1998Assignee: The Toro CompanyInventors: Anthony M.

Patent number: 4771549Abstract: Deviations in flatness on a horizontal surface are measured by running over the surface, at a constant driven speed, an instrument sensitive to slope and which generates a continuous voltage signal corresponding to a continuous slope measurement. The continuous voltage signal is filtered to remove extraneous high frequency voltage signals thereby to produce raw continuous analog slope data which is digitized and calibrated to provide calibrated digital slope data from which other flatness data is computed. Procedures are described for calibrating the instrument and for eliminating or compensating for distortions in the measurements.Type: GrantFiled: March 16, 1987Date of Patent: September 20, 1988Assignee: The Austin CompanyInventors: Donald R. Shelangoskie, Arthur A. Huckelbridge, Jr., Dario A. Gasparini, James T. Wright, Barry A. Rogers, Stephen Marine
