Abstract: A roof insulator support system includes a plurality of longitudinally extending beams supporting a plurality of regularly spaced, laterally extending purlins of Z-shaped cross section with an upturned lip portion on the lower flange of each purlin. Elongated liner support members, being extrusions of a generally inverted T-shape, are attached to and extend along the bottom of each purlin. Each liner support member is attached to a purlin by the interaction of a clip member which engages the lip portion of the purlin and a clip flange which engages the bottom of the lower flange of each purlin to prevent vertical displacement thereof. The horizontal portions of liner support members on adjacent pairs of purlins support roof liner panels laid between the purlins. A layer of insulation material is laid on top of the roof liner panels and a roof extends over the purlins.

Abstract: A prestressed concrete tank having a core wall comprising elongated panels of precast concrete having on their outer face a sheet of sheet metal presenting parallel, longitudinal, undercut channels, is shown. The precast panels are assembled and spaced, in side-by-side relationship. Two, laterally extending metal flanges which run parallel with the elongated sides of the panels are provided. The flanges on adjacent panels overlap one another and are fastened by means of sheet metal screws. The joint formed is sealed with an elastomeric material. The advantages of the tank configuration are that expensive cover plates as have heretofore been used are avoided and the joinery is reduced by approximately one half thereby reducing the cost of sealant material and the labor required to apply it, as well as substantially reducing the likelihood of leakage from the tank.

Abstract: A thermal insulating glazing unit comprising a plurality of elongated evacuated sealed glass tubes arranged adjacent each other with their axes parallel, transverse to the light. The inner side of each of the glass tubes is covered by an infrared-reflecting coating.

Abstract: The disclosure embraces a tubular article or cover adapted to enclose a bar, spindle or baluster, the article or cover comprising longitudinal mating hollow sections provided with projections and recesses, the mating sections, in assembly, enclosing a bar, spindle or baluster, the projections being received in the recesses, the dimensions of the projections and recesses providing interengagement effective to retain the sections together, the sections having interior configurations engageable with a bar, spindle or baluster to resist movement of the tubular article or cover relative to the bar, spindle or baluster.

Abstract: A support runner for use in a suspended ceiling system is disclosed with the support runner being useful in ceiling systems having an exposed flange for decorative purposes. The support runner has a decorative trim having a decorative lower surface and an engageable upper surface. An inverted-T runner is supportingly engaged about the engageable upper surface of the decorative trim and extends along the decorative trim a distance sufficiently less than the length of the trim to accomodate heat expansion distortion of the inverted-T runner. When the ceiling system is exposed to heat, the inverted-T runner continues to hold the ceiling panels even though the decorative trim becomes inoperable due to expansion caused by the heat.

Abstract: A log cabin type structure formed of horizontally arranged "log" type tongued and grooved planks having notched ends which are arranged to overlap and interfit with one another to form corners, and having holes drilled through such overlapping portions for reception of a vertical metal tie rod. In accordance with a feature of the invention, the holes are preferably slightly oversize with regard to the metal tie rod, thereby facilitating assembling of the structure. The holes in alternate logs will however be slightly misaligned with one another, such misalignment being produced in one of various different ways. As the logs are bedded down with one another, the misalignment of the holes causes the holes to bind tightly on the rod and thereby procures pressure on the log ends causing them to be drawn firmly into engagement with one another in the corners. Sealing surfaces formed transversely of the log ends are thus forced into pressurized mutually sealing engagement.

Abstract: A method of making a building panel and the panel made by the steps which include laying a mold form horizontally, laying bricks in the pattern indicated in the mold form and depositing a fibrous and cementitious mixture in the spaces between the bricks and over the tops of the bricks. Providing a reinforcing lattice work and forcing it into the still soft cementitious mixture. Subsequently, a resin insulating material is foamed in situ in the mold cavities formed between the elements of the lattice work. Optionally, a smooth finish coat of material may be troweled or sprayed over the insulation material.

Abstract: Techniques are described for forming an elevated concrete slab-like supporting platform. A sand blanket is installed on the platform site and supporting piles are driven down through the sand blanket. A concrete slat is poured over the sand blanket and a moat is dug around its periphery. Water jet nozzles are positioned within the sand blanket prior to pouring of the concrete slab; and water conduits are also provided to extend from outside the sand blanket to the nozzles. After the concrete slab hardens, water is pumped through the conduits to form water jets at the nozzles which wash the sand blanket out from under the slab.
