Patent number: 11214919Abstract: Methods of and systems for treating a web of chopped nonwoven mineral fibers passing through a chopped nonwoven mineral fiber mat process are provided. The methods comprise spraying strength aid onto the web of chopped nonwoven mineral fibers in a forming section of the chopped nonwoven mineral fiber mat process. The systems comprise a first spray bar comprising a delivery conduit configured to provide a flow of strength aid at a flow rate to one or more nozzles in fluid communication with the delivery conduit. The one or more nozzles are configured to receive the strength aid from the delivery conduit and to spray of the strength aid onto the web of chopped nonwoven mineral fibers in the forming section of the chopped nonwoven mineral fiber mat process.Type: GrantFiled: May 29, 2019Date of Patent: January 4, 2022Assignee: Ecolab USA Inc.Inventors: Adam Krause, James Rieck, David Lucas, Eric J. Ouderkirk, Janet R. Kirkman, Robert M. Lowe, Alexandra Knoth

Patent number: 9034459Abstract: Solar control films containing a visible light-transmissive flexible support, a first nucleating oxide seed layer, a first metal layer, an organic spacing layer, a second nucleating oxide seed layer, a second metal layer and a polymeric protective layer. The thicknesses of the metal layers and spacing layer are such that the films are visible light-transmissive and infrared-reflective. The films have high visible light transmittance, high Reflected Energy and low Total Solar Heat Transmission.Type: GrantFiled: December 16, 2008Date of Patent: May 19, 2015Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Peter D. Condo, Janet R. Kirkman, Clark I. Bright, Walter Stoss

Patent number: 8932701Abstract: An optical sheet suitable for use in a laminate comprising at least one glazing component. The optical sheet comprises a non-metallic multi-layer optical film that has multiple optical layers, and can be, for example, a solar energy reflective film (e.g., an infrared radiation reflective film). The multiple layers are thermally and/or otherwise fused together along all, substantially all or at least a substantial portion of the peripheral edge of at least the optical film, so as to prevent or at least substantially reduce the occurrence or degree of delamination of the multiple layers along all, substantially all, or the substantial portion of the peripheral edge of the optical film.Type: GrantFiled: February 23, 2004Date of Patent: January 13, 2015Assignee: 3M Innovative Properties CompanyInventors: Heather K. Kranz, Jeffrey A. Boettcher, Janet R. Kirkman, Peter T. Dietz

Patent number: 7189447Abstract: A transparent optical film laminate and a method of making such a laminate. The laminate can include a transparent optical sheet comprising a non-metallic multi-layer optical film sandwiched between first and second bonding sheets. The optical sheet and the bonding sheets are also sandwiched between two glazing components. A substantial portion of the peripheral edge of the optical film lies within or beyond the peripheral edge of at least one of the glazing components. The peripheral edge of the optical film may have a portion that lies within and a portion that lies beyond the peripheral edge of at least one of the glazing components.Type: GrantFiled: January 4, 2002Date of Patent: March 13, 2007Assignee: 3M Innovative Properties CompanyInventors: Thomas J. Conway, Janet R. Kirkman, Brian L. Koster, Heather K. Kranz, Bruce E. Tait, Einar O. Vaage
