Abstract: Blocks, weighing about 35 lbs., formed of a homogeneous mixture of about 75% gypsum and 25% lime, are strategically placed in surface water that is being damaged by acid rain, where, by timed release of lime, the pH of the water is maintained at about 6.5 pH.

Abstract: A method of mounting a gypsum wallboard in which the wallboard has a tear-resistant material partially adhered to the back face, with small slots in the material located at unadhered areas, through which small suspension clips are inserted. The clips include a hanger leg for hanging the clip on horizontal channels, which are part of the wall framing system.

Abstract: An extendible stud, consisting of two substantially identical Z-studs each of which has opposed flanges of substantially different widths and inwardly turned lips at the flange outer edges, and each Z-stud having a central raised ridge in its web, raised in a direction toward the wider flange, which two Z-studs are interconnected by the narrow flange of each being held within the channel formed by the wider flange of the other Z-stud along with its associated lip and web. Also the method of interconnecting two Z-studs and the method of erecting hollow partitions with the extendible stud.

Abstract: A gypsum wallboard suspension system in which the wallboard has a tear-resistant material partially adhered to the back face, with small slots in the material located at unadhered areas, through which small suspension clips are inserted. The clips include a hanger leg for hanging the clip on horizontal channels, which are part of the wall framing system.

Abstract: The method of manufacturing a predecorated gypsum wallboard face paper wherein a protective base coat is applied on the face paper by a rotogravure printing of the protective coat with minute openings very closely spaced throughout the coating, as by printing the coat in the form of reasonably uniformly sized tiny dots with about 1000 to about 100,000 dots per square inch, and a decorative coat is applied over the base coat.

Abstract: A notched metal channel having a small section of web removed and an adjacent short section of flange bent inwardly into the area of the removed section of web, and a hollow wall having such a notched channel forming part of the framing in the hollow of the wall, with elongate utilities in the wall extending substantially perpendicularly, relative to the channel, and extending between the channel notch and the adjacent wallboard forming the wall facing.

Abstract: A gypsum wallboard suspension system in which the wallboard has a tear-resistant material partially adhered to the back face, with small slots in the material located at unadhered areas, through which small suspension clips are inserted. The clips include a hanger leg for hanging the clip on horizontal channels, which are part of the wall framing system.

Abstract: An apparatus and method for forming a flat-bottomed V-groove in wallboard involving a pair of oppositely angled circular saws, wherein saw blades have an obtusely angled outer edge, as by grinding back one corner of each of a plurality of carbide tips on at least one of the two saw blades.

Abstract: A backer board for use as a base to which ceramic tile is bonded for a bathtub or shower area, in which the board is made by forming a gypsum core board with fiber glass laminated composite facings, which include an inner fiber glass scrim, an outer fiber glass nonwoven matte and an acrylic film, which film is formed of an acrylic latex of a class commonly employed as an ingredient in Portland cement mortar for applying ceramic tile.

Abstract: An extendable stud having a stud body and a stud extender telescopically engaged with the bottom of the stud body, in which the stud extender bottom end has an interlocking slot, engageable with an upwardly extending enlarged elongate head on a floor track, which becomes locked to the enlarged head by raising the stud from an angled engaging position to a vertical locked position, whereat the stud body can be easily moved upwardly, into a ceiling channel, forming an elongated stud.

Abstract: Elongate extruded sections of vinyl siding, having a top edge portion, which is intended to be hidden in use behind the bottom edge of an immediately higher section of siding, wherein the top edge portion is slit crosswise at a plurality of spaced apart locations, permitting freer expansion and contraction of the exposed portion of the siding with changes in temperature.

Abstract: An assembly of elements for providing a mounting surface for wall furniture includes a bracket which is attached to a wall framing member, at least one horizontally extending, inwardly opening, horizontally adjustable channel mounted on the bracket and preferably a second vertically extending, inwardly opening, vertically adjustable channel mounted on the first channel, providing a mounting surface which is both horizontally and vertically adjustable, to accommodate wall furniture having mounting means which are not spaced to coincide with the spacing of the wall framing members.

Abstract: An acoustical panel, for ceilings or for area separation, and the method of making such panels, wherein the panel consists essentially of a unitary frame consisting of four sides, each with an inwardly opening channel, an outwardly opening rebend and a downwardly extending flange, the panel further including a rigid gypsum board with edges filling the frame channel, a low density sound absorbing mat within the confines of the downwardly extending flanges, and a porous fabric facing concealing the acoustical mat and affixed to the frame by disposing the fabric edges in the outwardly opening rebends and crimping the rebends tightly closed.

Abstract: A hollow wall having a V-shaped rigid wire clip with two almost parallel legs engaged in holes in a metal element on a wallboard back face, with the clip head extending across the wallboard edge joint, to hold abutting wallboard edges coplanar, in which at least one of the clip legs has an intermediate bend engaging the hole periphery, whereby a thin tool, extended through the joint, can rotate the clip head around the intermediate bend, which is engaged with the hole periphery, which removes the clip head from behind one of the two abutting edges, for nondestructive removal of one of the wallboards of the wall.

Abstract: A clip for permitting attachment of wallboard to the open side of an outwardly opening C-shaped metal stud, including a clip body portion which engages three sides of the metal stud for increased stability, and a clip hanger portion which extends upwardly and inwardly through the stud open front side and has tabs which engage behind the flanges of the stud open front side.

Abstract: A hollow C-shaped vertical metal stud and a furniture bracket affixed thereto. The bracket includes a back plate which is disposed, at a rearwardly and a downwardly angle, within the confines of the stud, whereby weight of furniture on the bracket wedges the back plate between the stud front and back walls, preventing downward movement.

Abstract: A wall in which at least one wall trim member has a face portion, spaced outwardly from the plane of the wallboard, and has an angled sidewall which, by its angled nature, tends to blend with both the wall trim face portion and the wallboard surface, which angled side wall is removed in short sections of this first wall trim member whereat a second wall trim member, with a face coplanar with the first wall trim member face portion, is abutted against the first wall trim member.
