Patent number: 9848405Abstract: A system to control paging cycles in a wireless network assigns mobile stations to one of a plurality of paging groups based on the paging cycle requirements of the individual mobile stations. In addition, the mobile stations in a particular paging group are further subdivided into subgroups that may be substantially equal in size. At any particular paging cycle, only one subgroup of a particular paging group is included in the paging process thus reducing the overall number of mobile stations that need to be paged in any particular paging cycle.Type: GrantFiled: June 21, 2010Date of Patent: December 19, 2017Assignee: CLEARWIRE IP HOLDINGS L.L.C.Inventor: Esmail Dinan

Patent number: 8072090Abstract: A method of powering a multi-level structure is provided, which includes disposing a climate control system in the building. The system has a cooling tower, a fluid cooled chiller, a return line connecting an output of the chiller to an input of the cooling tower, and a condenser pump for pumping fluid therebetween. The system further includes a supply line connecting an output of the cooling tower to an input of the chiller, fluid being gravity fed from the cooling tower to the chiller. A turbine generator is disposed in the return line, the turbine generator being powered by fluid flowing through the return line. The method provides for transferring power generated from the turbine generator to a power supply for the structure.Type: GrantFiled: February 10, 2009Date of Patent: December 6, 2011Assignee: Tishman Speyer IP Holdings, L.L.C.Inventor: Joseph Szabo

Patent number: 6942809Abstract: This invention relates to a method for treating soybean refinery wastewater. More particularly, this invention relates to a method for treating soybean refinery wastewater with an aqueous iron salt solution to produce purified water. An aqueous iron salt solution is admixed with soybean refinery wastewater, the resulting mixture is agitated and passed through at least one filter device to form a filtered effluent, and the pH of the filtered effluent is adjusted to a value below about 8 to form purified water.Type: GrantFiled: June 13, 2003Date of Patent: September 13, 2005Assignee: IP Holdings, L.L.C.Inventor: Dick Copeland

Patent number: 6844458Abstract: The present invention relates to improved methods for refining vegetable oils. Vegetable oil is combined with organic acid and subjected to high shear to finely disperse the acid solution in the oil. The resulting acid-and-oil mixture is mixed at low shear for a time sufficient to sequester contaminants into a hydrated impurities phase, producing a purified vegetable oil phase.Type: GrantFiled: July 3, 2002Date of Patent: January 18, 2005Assignee: IP Holdings, L.L.C.Inventors: Dick Copeland, W. Maurice Belcher

Patent number: 6441209Abstract: This invention relates to improved methods for treating organic acid-treated phosphatides. More particularly, this invention relates to improved methods comprising providing a phosphatide-containing material obtained from organic acid refining of vegetable oil, adjusting the pH of the phosphatide-containing material to form a neutralized phosphatide, and drying the neutralized phosphatide for a time sufficient to produce a dried phosphatide containing hydrolyzed lecithin.Type: GrantFiled: February 2, 2001Date of Patent: August 27, 2002Assignee: IP Holdings, L.L.C.Inventors: Dick Copeland, W.

Patent number: 6172248Abstract: The present invention relates to improved methods for refining vegetable oils and byproducts thereof. This invention also relates to an improved process for deodorizing lecithin. The invention additionally relates to deodorized lecithin and deodorized vegetable oil obtained by improved processes of the invention. In an organic acid refining process, vegetable oil is combined with a dilute aqueous organic acid solution and subjected to high shear to finely disperse the acid solution in the oil. The resulting acid-and-oil mixture is mixed at low shear for a time sufficient to sequester contaminants into a hydrated impurities phase, producing a purified vegetable oil phase. In a lecithin deodorizing process, a phosphatide concentrate is contacted with steam in a dryer operating at a pressure below 50 mm Hg and at a temperature of less than about 150° F. to form lecithin containing no more than about 0.5 percent by weight water.Type: GrantFiled: November 20, 1998Date of Patent: January 9, 2001Assignee: IP Holdings, L.L.C.Inventors: Dick Copeland, W.
