Patent number: 7997282Abstract: A smoking article such as a cigarette comprises a tobacco rod and a filter component having a cavity filled with spherical beaded carbon. As mainstream tobacco smoke is drawn through the filter component, targeted gas phase smoke constituents are removed as the smoke passes through the carbon. During the filter manufacturing process the spherical beaded carbon flows like a liquid and substantially completely fills the cavity. Point-to-point contact between the spherical beads together with substantially complete filling of the cavity produces minimal channeling of ambulatory gas phase as well as maximum contact between the gas phase and the carbon surface of the spherical beads during smoking.Type: GrantFiled: October 31, 2007Date of Patent: August 16, 2011Assignee: Philip Morris USA Inc.Inventors: John B. Paine, III, Zuyin Yang, Kent B. Koller, Jay A. Fournier, Charles E. Thomas, Jr., Timothy S. Sherwood, Zhaohua Luan, Shuzhong Zhuang, Jose G. Nepomuceno, Diane L. Gee, Georgios D. Karles

Patent number: 7810505Abstract: An electrical smoking system includes a lighter having a plurality of electrical heater elements and a system for electrically actuating the heater elements. The lighter is adapted to receive a cigarette with the heater elements at least partially superposing a portion of the cigarette. The lighter further includes an electromagnet arranged in proximity to magnetic portions of the heater elements, with the electromagnet being actuable to selectively repulse or attract the heater elements.Type: GrantFiled: June 21, 2007Date of Patent: October 12, 2010Assignee: Philip Morris USA Inc.Inventor: Zuyin Yang

Publication number: 20070102013Abstract: A tobacco mass is heated to a temperature of about 150° to about 220° C. to release flavorful tobacco volatiles, which are entrained in air passing through the tobacco mass, and condensed to form an inhalable aerosol. The tobacco mass may have a rotationally symmetric shape, with at least part of its surface in heat transfer relationship with a heater. The heater may be an external shell, an internal rod, or a plate. A shell can enclose the heater and tobacco mass and define a preheating chamber for inflowing air. A mouthpiece, with or without a filter, may be arranged in fluid communication with the tobacco mass to direct the aerosol from the heating system.Type: ApplicationFiled: September 28, 2006Publication date: May 10, 2007Applicant: Philip Morris USA Inc.Inventors: John Adams, William Crowe, John Hearn, Robert Lee, Brett Stevenson, Zuyin Yang, James Baggett, John Hairfield, Steven Larson, Robert Ripley, Susan Wrenn

Publication number: 20050205102Abstract: A method of treating silica gel to improve its characteristics as a filter material. The method comprises the steps of preparing surface modified silica gel by introducing fluidizing gas into a reactor at least partially filled with silica gel particles so as to form a fluidized bed of the silica gel particles; and introducing a liquid reagent into the reactor so as to modify the surface of the silica gel particles by covalently bonding at least one functional group thereto. The liquid reagent may be prepared such that the functional group includes a 3-aminopropylsilyl group, a N-[2-aminoethyl]-3-aminopropylsilyl group, a N-[N-(2-aminoethyl)-2-aminoethyl]-3-aminopropylsilyl group or a mixture thereof. The liquid reagent can be an aqueous or non-aqueous solution containing 3-aminopropyltriethoxysilane, 3-aminopropyltrimethoxysilane, N-[3-(trimethoxysilyl)propyl]-ethylenediamine and/or N?-[3-(trimethoxysilyl)propyl]-diethylenetriamine.Type: ApplicationFiled: January 27, 2005Publication date: September 22, 2005Inventors: Zuyin Yang, John Paine
