Patent number: 8182652Abstract: An acoustical panel is made by applying a thin, acoustically-transparent coating to an acoustical base mat. A pulp is made from one or more fillers, a fibrous filler, a binder and water. A thickener solution is prepared from a thickener and water. A portion of the pulp and the thickener solution are mixed under high shear conditions to degrade the fibrous filler and form a smooth coating. The coating is applied to and distributed over a base mat and the coated base mat is then cut and dried to form a coated acoustical panel. The panel is free of visible mineral nodules on the surface of the coating. Optionally, the pulp is a portion of a pulp used to make the base mat. Other embodiments include the use of recycled dust or fine particles of the acoustical panel obtained from cutting or shaping the base mat or coated panels.Type: GrantFiled: March 23, 2010Date of Patent: May 22, 2012Assignee: United States Gypsum CompanyInventors: Mark Englert, Runhai Lu, Matthew Langdon

Publication number: 20110247894Abstract: A lightweight cast article that is made by the method of the present invention. A foamed acoustical product is prepared by blending a starch with cold water, then heating the starch/water blend to form a starch gel. Mineral wool is added to the starch gel to form a pulp and the pulp is wet-mixed until wool nodules are formed. The pulp is then combined with a surfactant and an amount of foam water. The foaming agent is selected from the group consisting of a linear sodium dodecylbenzene sulfonate, a cocamidopropyl betaine, a cocamidopropyl hydroxysultaine, their salts and mixtures thereof. Mixing of the foaming agent and pulp continues to form a foamed pulp. The foamed pulp is cast into a mold and allowing the foamed pulp to dry forming a foamed product. The foamed product is removed from the mold.Type: ApplicationFiled: April 13, 2010Publication date: October 13, 2011Inventor: Mark Englert

Publication number: 20070045892Abstract: The invention provides a board forming system comprising a forming table comprising a belt with a surface for conveying a backing layer; a mixer fitted with a mechanism capable of depositing cementitious slurry material over a top surface of the backing layer; and a slurry spreader positioned downstream of the mixer, wherein a portion of the slurry spreader comprises a plurality of apertures which are connected to a source of pressurized fluid. The slurry spreader is configured such that the pressurized fluid flows out of the slurry spreader through the apertures so as to provide a continuous film of fluid across an outer surface of the slurry spreader. The slurry spreader is positioned such that it can contact at least a portion of the cementitious slurry after the slurry exits the discharge and before the slurry is spread across the width of the backing layer such that the thickness of the slurry is approximately equal to the desired slurry thickness for board formation.Type: ApplicationFiled: September 1, 2005Publication date: March 1, 2007Applicant: United States Gypsum CompanyInventors: Steven Sucech, Mark Englert, William Frank, Raymond Mlinac, Srinivas Veeramasuneni

Patent number: 7056460Abstract: A process for making an improved gypsum/wood fiber board is described. Products resulting from the process are also described. The process comprises adding a diisocyanate, specifically methylenediphenyldiisocyanate (MDI) to an aqueous slurry of calcium sulfate material and cellulosic fibers, where the MDI is added as an emulsion stable in the conditions in which the slurry is maintained. The process further includes passing the MDI containing slurry onto a flat porous forming surface to form a filter cake; removing a substantial portion of the water from the filter cake through the porous surface; pressing the filter cake to form a board and remove additional water; and drying the board to remove the remaining free water.Type: GrantFiled: January 14, 2003Date of Patent: June 6, 2006Assignee: United States Gypsum CompanyInventor: Mark Englert
