Patent number: 10837172Abstract: A drywall sheet with a gypsum core sheathed in front and rear paper layers, an edge of the sheet being tapered towards the rear, the taper being formed by a flap of a marginal area of the front paper and a thin layer of gypsum attached to an inner side of the front paper margin being folded into a space resulting from a slot cut in the sheet edge to a depth generally equal to the width of the flap, the flap being held in place by a continuous layer of a hot melt adhesive occupying a space of the slot not occupied by the flap and having an elasticity that imparts fastener penetration resistance to the associated edge from a front face of the sheet.Type: GrantFiled: September 11, 2019Date of Patent: November 17, 2020Assignee: USG INTERIORS, LLCInventors: Michael P. Spihlman, Peder J. Gulbrandsen, Samuel D. Hulka

Patent number: 10590288Abstract: A formulation for an acoustically transparent coating for use on an acoustical substrate comprising a water dispersible binder and relatively large filler particles, and characterized by a high pigment to volume concentration, high viscosity, high shear thinning, and fast drying to enable the formulation to be sprayed in droplets that retain their identity when in mutual contact and in a dry coating can be efficiently sanded flat.Type: GrantFiled: May 22, 2019Date of Patent: March 17, 2020Assignee: USG INTERIORS, LLCInventors: Samuel D. Hulka, Peder J. Gulbrandsen, Rafael Bury
