Patent number: 10535853Abstract: The disclosure describes compositions and methods for producing a change in the voltage at which hydrogen gas is produced in a lead acid battery. The compositions and methods relate to producing a concentration of one or more metal ions in the lead acid battery electrolyte. The compositions include glass based compositions that are included as part of various battery components, such as the battery separator, pasting paper, additives to battery paste, etc.Type: GrantFiled: September 21, 2011Date of Patent: January 14, 2020Assignee: Hollingsworth & Vose CompanyInventors: John Wertz, Christopher Campion, Yuri Vulfson, Rene Gargan, Nicolas Clement, Randall Keisler

Patent number: 10022657Abstract: Filter media, including those suitable for hydraulic applications, and related components, systems, and methods associated therewith are provided. The filter media described herein may include two or more layers, at least one of the layers having a relatively high percentage of microglass fibers. Additionally, the filter media may be designed such that the ratio of average fiber diameters between two layers is relatively small, which can lead to a relatively low resistance ratio between the layers. The filter media has desirable properties including high dirt holding capacity with low basis weight and a low resistance to fluid flow. The media may be incorporated into a variety of filter element products including hydraulic filters.Type: GrantFiled: December 29, 2014Date of Patent: July 17, 2018Assignee: Hollingsworth & Vose CompanyInventors: Milind Godsay, Randall Keisler

Publication number: 20150157969Abstract: Filter media suitable for various applications and related components, systems, and methods associated therewith are described. The filter media may include a composite filter media structure having a substrate and at least one fine fiber layer. The fine fiber layer may include a plurality of glass fibers having an average fiber diameter of less than 2 microns; or, at least 70% by weight of the glass fibers within the fine fiber layer has a fiber diameter of less than 2 microns. The fine fiber layer may further include a fluorochemical composition, an organosilicon composition and may optionally include a binder composition that comprises less than 2% by weight of the fine fiber layer. The filter media may exhibit both a relatively high gamma and favorable mechanical properties. The filter media may be produced by forming a substrate on the surface of a wire in a wet laid process, and forming a fine fiber layer on the substrate while the substrate is on the wire.Type: ApplicationFiled: December 5, 2013Publication date: June 11, 2015Applicant: Hollingsworth & Vose CompanyInventors: David F.
