Patent number: 8793105Abstract: The present invention relates to a method for airborne particle contamination control, comprising: creating a simulation by modeling a turbulent airflow in an environment that includes an equipment of interest; plotting a flow parameter on the simulation to visualize a flow field of air according to a current design; creating an injection point on the simulation for particles in the environment; determining a particle concentration of the particles; determining, by a computing device and from the particle concentration, whether the current design provides contamination control; in response to determining that the current design does not provide contamination control, creating a modified design; and providing the modified design for implementation. The present invention further relates to a computing device for airborne particle contamination control. The present invention still further relates to a non-transitory computer-readable medium for airborne particle contamination control.Type: GrantFiled: March 31, 2011Date of Patent: July 29, 2014Assignee: The Procter & Gamble CompanyInventors: Shirdish Poondru, Mel Allende-Blanco, Joseph Francis Kitching, Savas Aydore, Hasan Eroglu, Krista Beth Comstock, Jianjun Feng, Yunpeng Yang, John Ferney McKibben, James Kenneth Comer, Jr.

Patent number: 7939010Abstract: An improved method for creating fibers from a material dissolved in a solvent. In one embodiment, the method includes the steps of feeding a fiber making material dissolved in a solvent through a die including at least two rows of nozzles to form fiber strands. An attenuation medium is provided about the fiber strands. The attenuation medium is provided in a direction that is generally parallel to the fiber strands such that the attenuation medium elongates the fiber strands. The attenuation medium has a relative solvent-vapor content of at least about 50 percent.Type: GrantFiled: November 17, 2005Date of Patent: May 10, 2011Assignee: The Procter & Gamble CompanyInventors: Michael David James, Stanford Royce Jackson, Savas Aydore, Hasan Eroglu, Donald Eugene Ensign, Paul Dennis Trokhan, Edwin Arthur Stewart
