Abstract: Disclosed is a new guide for brick laying for facilitating uniform arrangement of bricks during construction of floors, walkways, patios, and the like. The guide comprises a rectangular lattice panel having square openings for temporary placement flat on top of a prepared work area whereby bricks placed inside the square openings will automatically align to a desired pattern. A handle is included whereby a user may easily grasp the panel after brick placement to facilitate removal of the panel without disturbing alignment of the bricks. The lattice panel is separated longitudinally into hingedly connected left and right half panels for providing an operating position wherein the half panels extend coplanarly relative to each other and a storage/transport position wherein the right half panel is pivoted 180.degree. to lie adjacent the left half panel. A latch is additionally included whereby the panels may be releasably locked in the operating position to prevent unwanted pivotal movement thereof.

Abstract: The invention is directed to a containment box for use during window frame removal or other building structure modification to prevent toxic material from entering the environment; and particularly inhabited areas of the building.

Abstract: The covering section bar has a generally U-shaped inner housing defined by two side branches and a cross-bar, the first side branch having a fastening or snap-fastening shoulder and being elastically deformable at a first level of deformation, being of a thickness that is less than the mean thickness of the section bar, at least in the zone thereof where elastic deformation is required; the inner housing includes a first bearing zone corresponding to the fastening shoulder or situated close to the snap-fastening shoulder, a second bearing zone situated on the same side of the inner housing, and a third bearing zone situated on the second side branch and located in between the two first-mentioned bearing zones. The section bar covers either a panel or a panel-fastening section bar, after one or other of them has been inserted in its inner housing. The combination of the covering section bar and of the fastening section bar constitutes a panel frame element.

Abstract: A panel assembly that may be used in doors, particularly hollow metal doors, and other types of panels such as interior and exterior walls, room partitions, and the like. The panel assembly exemplified by a hollow or filled metal door is constructed from a deep pan and a shallow pan made from unitary pieces of sheet metal sheet and each pan includes top, bottom, and two opposing side flanges extending from rectangular face members. The flanges of the deep pan are substantially perpendicular to its rectangular face member and higher than those of the shallow pan. Side flanges of one of the pans have first latch members formed along free side edges of their side flanges remote from their respective face member and side flanges of the other pan have second mating latch members formed along free side edges of their side flanges remote from their respective face members.

Abstract: A low cost relatively simple method is presented for patching single ply roof membrane derived from chlorosulfonated polyethylene by using a procedure involving N-methyl-2-pyrrolidone or NMP chemical liquid activator with proper steps therebetween and subsequently completing the patching method by following standard known welding procedures. This method results in a welded seam that can be made as strong as the roof membrane itself.

Abstract: A door and floor molding which includes a stationary piece and removable piece. When used as a door molding, the stationary piece is attached abutting a doorway or window and when used as a floor molding is attached a distance above the floor. The distance above the floor is dependent upon the width of the mid section of the removable piece. A lip of the removable piece extends above the mid section and is slideably engaged within a clamping pocket of the stationary piece. A stabilizing wall of the removable piece lies substantially perpendicular to the lip and extends on both sides of a plane of the lip. The stabilizing wall engages the wall in a manner so as to press the mid section against the stationary piece and provide a more secure fit. The removable piece may be removed from its position within the stationary piece to aid in painting around or running wires through the molding.

Abstract: An overhead garage door panel has a thin outer metal skin. Along the upper and lower edges of the outer metal skin are top and bottom flanges. The top flange has a rib formed therein which is adapted to mate with a groove formed in the bottom flange of an adjacent corresponding panel. A foam insertion core fills the pan and flanges of the outer skin thereby providing the requisite strength and rigidity in combination with the flanges. The foam core is formed in-situ and a back skin extending between the flanges retains the foam within the panel during the foaming process. Adjacent panels are hinged together and a reinforcing member is glued within each flange to provide a secure mounting attachment for the hinges.

Abstract: A wall panel, especially double-wall panel, for building a large shuttering wall, from a plurality of wall panels whose lateral abutment edges flushly abut each other, the wall panel comprising a main plate having rectilinear first and second lateral abutment edges parallel to each other on a first large face of the main plate. On the other large face of the main plate a platelike suspension tooth obliquely and descendingly projecting from the first abutment edge is arranged behind the first abutment edge, while a suspension recess adapted to the suspension tooth is arranged behind the second abutment edge. Thereby, the wall panels can be slidingly suspended into each other, until the abutment edges of the two wall panels adjoining each other come into contact with one another.

Abstract: A foldable floor track or ceiling track having 1/8-inch-wide slots in the flanges and a 1/8-inch-high rib in the web, between the slots, permitting the track to be cleanly folded in half at the factory, for convenient packaging and handling, and then unfolded and fastened to the floor and the ceiling at a job site.

Abstract: A pool deck protector cooperative with the perimeter coping of the pool to prevent wear and discoloration to the pool deck and pool coping by the tie-down assembly securing the pool cover to a pool cover anchor. The pool deck protector is generally planar with one edge curved under upon the underside of the planar member, the curved edge having a decreasing radius such that it is frictionally engageable in a snap-fit manner with the perimeter coping of the pool to position the pool deck protector in alignment with the tie-down assembly thereby protecting the perimeter coping and immediate pool deck area.

Abstract: A clip device for locating an object such as a diffuser in an aperture in a panel comprises a mounting member, a pivotal member, a spring for retaining the pivotal member in either of a first position and second position, and an actuating device comprising a rod and lug whereby the pivotal member can be moved form the first position to the second position. The rod is moveable between an operative condition wherein an end protrudes so as to contact the ceiling panel during insertion of the diffuser in the aperture, and an inoperative condition wherein the end is retracted. The clip can thus be selectively set so as not to operate when the diffuser is installed in the aperture.
