PASTING PAPERS AND CAPACITANCE LAYERS FOR BATTERIES COMPRISING MULTIPLE FIBER TYPES AND/OR PARTICLES
Publication number: 20190393464Abstract: Articles and methods involving pasting papers and/or capacitance layers are generally provided. The pasting paper may comprise a capacitance layer, and/or a stand-alone capacitance layer may be provided. In some embodiments, a pasting paper may comprise a plurality of cellulose fibers, a plurality of multicomponent fibers, and a plurality of glass fibers. In some embodiments, a pasting paper may comprise a plurality of conductive species, a plurality of capacitive species, and/or a plurality of inorganic particles. In some embodiments, a pasting paper may be disposed on a battery paste, such as a battery paste for use in a lead-acid battery. In some cases, forming a battery plate may comprise disposing a pasting paper on a battery paste. In some cases, a lead-acid battery may be assembled by assembling a first battery plate comprising a pasting paper with a separator and a second battery plate.Type: ApplicationFiled: June 7, 2019Publication date: December 26, 2019Applicant: Hollingsworth & Vose CompanyInventors: Teresa Grocela Rocha, Angelika Mayman, Nicolas Clement, John A.

Publication number: 20180001244Abstract: Filter media for filtering gas streams (e.g., air) are described herein. In some embodiments, the filter media may be designed to have desirable properties such as stable filtration efficiency, high oil repellency, low instantaneous resistance, and/or stable service life. One or more layers of the media may have a certain value of thickness over instantaneous resistance (and/or a ratio of thickness over instantaneous resistance between two layers). The filter media described herein may be particularly well-suited for applications that involve filtering gas streams (e.g., face masks, cabin air filtration, vacuum filtration, respirator equipment), though the media may also be used in other applications.Type: ApplicationFiled: July 1, 2016Publication date: January 4, 2018Applicant: Hollingsworth & Vose CompanyInventors: Siqiang Zhu, Mark A.

Publication number: 20040240385Abstract: Systems and methods for managing deployed trunk circuit capacity in a telecommunications network are disclosed. The usage of groups of trunk circuits in the network can be monitored to collect network traffic data. Analysis of the traffic data provides for computation of performance metrics and calculation of time-moving averages. The analyzed data is input into forecasting models to plan network capacity deployments to meet the expected demand. Network equipment and facilities are provisioned to meet the forecasted plan. Connection routing is adjusted to utilize the provisioned equipment and facilities.Type: ApplicationFiled: April 15, 2004Publication date: December 2, 2004Inventors: Ronald L. Boggs, Dean W.
