Publication number: 20230372850Abstract: It is described herein a filter media comprising at least a first layer comprising first fibers and a second layer comprising second fibers. The first fibers may comprise synthetic fibers in an amount of at least 50 wt. % based on total weight of the fibers in the first layer. The second fibers may comprise cellulosic fibers in an amount of at least 30 wt. % based on total weight of the fibers in the second layer. The first layer may be joined to the second layer with an interface between the first layer and the second layer comprising a mixture of the first fibers and the second fibers such that a z-directional tensile strength (zdt) across the first layer and the second layer—in the absence of a secondary adhesive—is at least 0.5 psi. It is also described herein a process to produce such a filter media, and a filter element comprising such a filter media.Type: ApplicationFiled: January 28, 2022Publication date: November 23, 2023Inventors: David Alan TOPOLENSKI, Kent WILLIAMSON, Andrew GOODBY, Mike HADY, Steven SHANNON, Jeffrey LADWIG

Publication number: 20220217484Abstract: Examples of hearing assistance devices are described. The hearing assistance devices include an enclosing structure configured to house a receiver that generates sound waves into an ear canal of a user when the hearing assistance device is worn, and a tube coupled to the receiver to direct the sound waves into the ear canal of the user. The tube may include magnetized particles that form a magnetic field through the tube. The tube may include a portion of hydrophilic coating and a portion of hydrophobic coating. The hearing assistance device may include a coiled wire configured to carry an alternating current to generate an electro-magnetic field through the tube.Type: ApplicationFiled: March 22, 2022Publication date: July 7, 2022Inventors: Timothy Brent Wilburn, SR., Thomas Howard Burns, Westley G. Gentry, Kent Williamson

Publication number: 20220080340Abstract: A filtration media with improved filtration, strength, tear resistance and air permeability in the form of a relatively thin and lightweight wet-laid fibrous web that has a wet Mullen ratio of 60% to 80% to ensure that the media is flexible enough to be formed into a fluted structure, and strong enough to retain the fluted structure when wound into a roll and to permit further processing without the media becoming too brittle. The filtration media comprises a blend of cellulose and synthetic fibers having a weight percent of 81 wt % to 87 wt % of a weight of the media and a resin binder having a weight of 13 wt % to 19 wt % (preferably about 16 wt %) of the weight of the media.Type: ApplicationFiled: November 22, 2021Publication date: March 17, 2022Applicants: AHLSTROM-MUNKSJÖ OYJ, DONALDSON COMPANY, INC.Inventors: KEVIN R. SCHOUWEILER, KENT WILLIAMSON, KRISTIN AMSDEN, STEVEN D. SCHMEICHEL

Patent number: 9415284Abstract: The handle portion (the initial 18?) of the bat is formed with a spiral groove with succeeding revolutions spaced by a distance in the range of between ¼? and ½?. A 30 lb test fishing line is secured in the groove by adhesive and the handle is coated with an non-drip epoxy which is then over coated with elastomer which is preferably shavings from recycled tires. The finished handle is created by sanding the elastomer to form a smooth grip which is contiguous with the initial end of the bat's barrel.Type: GrantFiled: August 21, 2015Date of Patent: August 16, 2016Inventor: J.
