Publication number: 20190280273Abstract: Non-woven webs that can be used as battery separators for batteries, such as lead acid batteries, are generally provided. In some embodiments, battery separators comprising a non-woven web including one or more chemical additives are provided. The chemical additives may impart beneficial properties, such as enhanced separator stability and/or battery performance. In some embodiments, the chemical additive(s) may confer resistance to oxidation, heavy metal deposition, and/or formation of short circuits during cycling of a battery including the battery separator. The respective characteristics and/or amounts of the chemical additive(s) may be selected to impart desirable properties while having relatively minimal or no adverse effects on another property of the battery separator and/or the battery.Type: ApplicationFiled: February 22, 2019Publication date: September 12, 2019Applicant: Hollingsworth & Vose CompanyInventors: Gubbi Krishnappa Natesh, Mahadevaswamy Kodimole Mahadevappa, Krishna Marchigowda, Harish Moddegowdru Ramaswamy, Akshay Ashirgade, Nicolas Clement, John A.

Publication number: 20190263717Abstract: Fiber webs that may be coated and used in filter media are provided. In some embodiments, the fiber web is a non-woven web that is coated with a resin including at least two components (e.g., a first component and a second component) that may react with one another to form a copolymer. In some embodiments, the coated fiber web may be sufficiently self-supporting, durable, and strong, such that filter media and/or elements formed of the web do not require additional support structures (e.g., a scrim).Type: ApplicationFiled: March 1, 2019Publication date: August 29, 2019Applicant: Hollingsworth & Vose CompanyInventors: Richard O.

Publication number: 20180269452Abstract: In some embodiments, a battery separator described herein may comprise a layer having a relatively low apparent density; for example, the density that includes any unoccupied space within the outermost boundaries of the layer may be relatively low. The low apparent density may be attributed to, at least in part, the geometry of the layer. For instance, in some embodiments, the layer may include undulations and/or have at least one non-planar surface (e.g., a corrugated layer; an embossed layer). In some embodiments, a battery comprising a layer having a relatively low apparent density may have desirable properties, including relatively low electrical resistance and/or relatively high capacity. The battery separators described herein may be well suited for a variety of battery types, including lead acid batteries.Type: ApplicationFiled: May 18, 2018Publication date: September 20, 2018Applicant: Hollingsworth & Vose CompanyInventors: Gubbi Krishnappa Natesh, Krishna Marchigowda, Basavaraju Girisha, Kameswara Rao Patchigolla Venkata, Nicolas Clement, Akshay Ashirgade, Sachin Kumar, John A.

Patent number: 9243083Abstract: The present invention relates to thiol-ene curing compositions, which cure upon exposure to ultraviolet (UV) light and/or heat. The compositions include components having alkenyl (or “ene”) functionality and components having thiol functionality, which undergo thiol-ene curing. The compositions also include a cure system. More specifically, in some embodiments, the curable compositions include a vinyl polymer bearing alkenyl or thiol terminal functional group(s) and a cross-linking agent having the opposing functionality, i.e., thiol cross-linking agents with alkenyl-terminated vinyl polymers and vinyl cross-linking agents with thiol-terminated vinyl polymers. Also provided are methods of making and using the compositions, such as for sealants for in-place gasketing applications.Type: GrantFiled: April 3, 2008Date of Patent: January 26, 2016Assignee: Henkel IP & Holding GmbHInventors: John G.

Patent number: 5009679Abstract: The present invention is a class of semi-permeable polymeric membranes and processes for using such membranes to separate one or more components of a gas mixture. The membranes are formed from aromatic polyimides derived from reaction of a 9,9-bis-(3,4-dicarboxyphenyl)-fluorene dianhydride and at least one aromatic diamine. These polyimide membranes exhibit high gas perm-selectivities and are especially useful in effecting the separation of oxygen and nitrogen from air.Type: GrantFiled: May 25, 1990Date of Patent: April 23, 1991Assignee: Air Products and Chemicals, Inc.Inventors: Richard O.
