Abstract: A frame for a louver holds the louver below the ceiling surface, away from a light fixture. This helps to collimate the light rays and direct the light downward, thus preventing unwanted sideways glare. In addition, the use of a frame tends to hold the louver more securely in the ceiling framework. The frame is formed of Z-shaped members, with one arm of the Z resting on the T-bar cross-bar and the other arm supporting the louver. A stop along one side of the frame prevents movement of the louver in the frame. In one aspect of the invention, rotatable angle supports at the ends of the frame rotate from a vertical position for use during louver installation to a horizontal supporting position for supporting the louver in the frame.

Abstract: It is known in structural curtainwall systems to have a series of rafters and purlins supporting glass panes. It known also to provide drainage panels in the supporting elements to drain away any water which seeps past the external surfaces of the glass panes. In this invention, separate panels are formed comprising purlins and sub-frame members and supporting glass panes. These panels will be formed off-site in a factory. The sub-frames of the panels are received directly into channels in the rafters thus enhancing the resistance of the system to leakage particularly where the panels intersect the rafters. The joint between adjacent panels spanning the same pair of rafters is sealed by providing tongue members on the purlins which are resiliently deformable. The biasing of the tongue members provides a seal between adjacent panels. Furthermore, the tongue members form drainage channels to drain water into the drainage channels of the rafters.

Abstract: A glass construction block comprising a plurality of glass members, each of which has a front wall, a rear wall and a plurality of side walls. A frame surrounds the glass members and is secured to the glass members spacing the glass members apart from each other while holding the glass members in a static position. The frame defines a channel member with side walls which extend inward from the outer side edge of the glass members terminating in a bottom wall and has flange portions which extend outward and are secured to the side walls. The blocks are assembled as a wall system by fitting a positive rib placed into the channel member into the channel member of an adjacent block. The two are adjoined with a void between the edges of the blocks which is then filled with a sealant.

Abstract: A wall for a rampart or building, consisting of a plurality of building blocks, each comprising slightly compacted sawdust or wood chips glued with resin. The building blocks are interconnected by a number of assembling pins and by recesses integral to the respective blocks, so as to frictionally engage into one another. There are also provided full length projections and corresponding grooves of the respective blocks for the same purposes. The thus erected structure is remarkable by the quality of the joints and by the ease and quickness of its assembly or disassembly.

Abstract: Principal members of structures are manufactured as foldable assemblies of like size and shape structural members, foldable for handling, packaging, shipping, and storage, and unfolded into their respective principal member configurations. Each like size and shape structural member has its opposite end surfaces formed on a sixty degree bias, whereby one longitudinal edge surface is longer than the other opposite edge surface, thereby creating opposite trapezoidal side surfaces. Each of these members has two spaced holes formed along its centerline, and each of these holes is equally spaced from a respective bias end. Regarding relative design dimensions, the respective longitudinal centerline length of each like size and shaped structural member is given the formula dimension, L, then the space between holes, X, is equal to 0.464L, and the space from each hole to centerline end, Y, is equal to 0.268L.

Abstract: A suspended grid system to support screw applied drywall ceilings. The system includes parallel rows of main runners suspended from the structural ceiling. Cross channel members are attached in parallel rows at right angles to the main runners. Drywall is screw attached to the lower surface of the cross channel members. Connectors are formed on the ends of the cross channel members which engage and lock to the main runners. Each such connector uses two upper latches and two lower tongue shaped stop shoulders. The lower stop shoulders will collapse in a controlled manner to relieve excessive compression as would be created from thermal expansion. The main runner will also provide a means for relieving thermal expansion.

Axially parallel recesses are provided in the walls of the strut rods, and the recesses have a width corresponding to the thickness of the joint plates. The recesses extend diagonally through the foam core of the strut rods, and the joint plates are inserted into the recesses where they are glued in place. The transverse rods are provided with slots in the ends thereof. The joint plates are inserted into the slots and glued to join the strut rods to the transverse rods.

Abstract: A black magician's wand with white tips with a built in flash at one end and a triggering means contained therein. The method of triggering the flash is concealed. In one version of the wand, the flash is triggered by means of a push button switch. In another version of the invention, the flash is triggered by means of a mercury tilt switch within the wand. Manipulation of the wand through a horizontal plane causes the switch to activate the flash.

Abstract: The floor system comprises spaced parallel horizontal planks, each including a metal inverted channel comprising a deck member having two spaced depending structural flanges and two laterally projecting edge channels thereon, each having a depending leg and an in-turned lower leg with a slot between each lower leg and the adjacent structural flange. U-shaped connectors extend between the planks and have upturned flanges with in-turned hook members received in the slots and interlocking with the edge channels. Soft rubber-like cylindrical stops are tightly fitted into the slots adjacent opposite ends of the connectors to prevent sliding movement thereof. Each inverted channel has a heat insulating resinous plastic cushioning cover with a top wall over the deck member, side walls enclosing the depending legs, and in-turned horizontal flanges clamped to the lower legs. Depending drip lips extend along the lower edges of the side walls of the cover.
