Publication number: 20090173353Abstract: Self-fitting device for location in ear canal and related method, including a bladder joined with a pump assembly via a valve assembly. The pump assembly transfers air to the bladder and achieves a predetermined pressure with the chamber regardless of ear canal size. The predetermined pressure may be achieved by reducing excess air pressure through the valve assembly.Type: ApplicationFiled: December 14, 2007Publication date: July 9, 2009Inventors: Ricky Wayne Purcell, Debra N. Welchel, Robert A. Drew, Shawn E. Jenkins, Jeffrey Jennings Krueger

Patent number: 6939440Abstract: Paper products, such as wiping products, are disclosed that have a fabric-imprinted pattern in combination with a crepe pattern. In producing paper products according to the invention, a base web containing pulp fibers is formed. Once the base web is substantially dry, the web is creped to form a first pattern. The creped web is then placed between two moving conveyors and guided around one or more compression inducing elements. As the web is guided around the compression inducing element in between the two conveyors, shear forces and compressive forces are imparted to the web that form a fabric-imprinted pattern superimposed on the crepe pattern. In one embodiment, the fabric-imprinted pattern comprises high density troughs.Type: GrantFiled: December 18, 2002Date of Patent: September 6, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Robert A. Drew, Frank G. Druecke, Patricia Riedl, Peter J. Allen

Publication number: 20030201081Abstract: A process for increasing the tactile properties of a base web without adversely effecting the strength of the web is disclosed. In one embodiment, the process includes the steps of placing a creped base web between a first moving conveyor and a second moving conveyor. The conveyors are then wrapped around a shear-inducing roll which creates shear forces and compressive forces that act upon the base web. The shear forces disrupt the web, increasing the softness and decreasing the stiffness of the web. The compressive forces are localized at the areas where the fabric knuckles contact the base web, imparting a unique fabric-imprinted pattern to the web with limited caliper reduction. The shear-inducing roll typically has a relatively small diameter. In some applications, more than one shear-inducing roll may be incorporated into the system.Type: ApplicationFiled: December 18, 2002Publication date: October 30, 2003Inventors: Robert A. Drew, Frank G. Druecke, Patricia Riedl, Peter J. Allen
