Patent number: 4513051Abstract: Strong, soft, absorbent tissue paper products comprising a substrate carrying an emollient. The substrate is planar and is formed of one or more tissue paper sheets. At least one of its two major surfaces must be soft, relatively untextured, and smooth. The emollient is distributed over at least a major portion of the smooth surface. In preferred embodiments, the substrate consists of two plies of tissue paper.

Patent number: 4289554Abstract: A method for making a unitized, ready-to-install, mobile home ceiling structure is disclosed. The method comprises the steps of arranging a plurality of rectangular panels on a tunnel jig. A roof frame structure is then positioned and fastened on the back face surfaces of the panels by means of fasteners and adhesive along the bottom chords of intermediate roof frame truss members. The method additionally includes the step of fastening roof frame perimeter side edge rails and outer truss members to the panel arrangement perimeter by means of fasteners driven upwardly through the front face surface of the panels to extend through the panels and penetrate the side edges rails and outer truss members. The method includes the step of transporting the mobile home ceiling structure from the tunnel jig in ready-to-install condition wherein the setup time of the adhesive material does not restrict moving the unit.Type: GrantFiled: May 12, 1980Date of Patent: September 15, 1981Assignee: United States Gypsum CompanyInventors: James E.
