Abstract: A hemispherically shaped membrane switch assembly for attaching to generally hemispherical surfaces such as cathode ray tubes is disclosed. Also disclosed are a method and apparatus for forming the assembly. The assembly is comprised of two layers of transparent film having spaced-apart conductors on the internal surfaces of both layers.

The assembly is hemispherically formed to the same radius as the hemispherical surface on which the assembly is to be mounted. The assembly mounts flush to the hemispherical surface and conforms uniformly to its surface thus reducing distortion and parallax.

Abstract: Apparatus for magnetically encoding a card which includes a timing wheel frictionally engaging the card as the card is moved along a slot. The wheel has about its peripheral annulus a series of evenly spaced magnetic timing bits which are read out by a read head located adjacent the annular surface of the wheel.

Abstract: A fire-rated type suspension ceiling grid runner is disclosed having expansion means intermediate its ends which collapse when the runner expands due to elevated temperatures occurring during a fire or the like. The runner provides a boxlike panel supporting flange along the lower end of the web thereof in which slots are formed to define a flange segment and connecting legs. When the expansion means collapses, the flange segment is laterally displaced as a unit and remains connected to each adjacent portion of the boxlike flange by at least two longitudinally spaced legs. The displaced flange segment functions as a bridging beam which continues to connect the adjacent portions of the flange and maintain them in alignment so that a grid formed of the runners can continue to maintain proper support for panel even when fire conditions occur.

The wall panels rest on the piers and are secured via weld plates and at spaced points to the ends of the floor panels. The floor panels and the roof panels incorporate a unique T-beam construction which in conjunction with the integrally cast complementary pairs of triangularly shaped floor and/or roof panel portions, is reinforced with steel.

Abstract: A neat, finish quality trim joint is prepared between an upstanding dry wall partition and the ceiling to conceal a gap and ragged upper edge of the partition left during erection of the partition. An elongated, inverted, transversely L-shaped member of the joint is secured to the face of the partition along the upper marginal edge thereof in such a manner that the vertically extending leg of the member covers the gap while its other, horizontally extending leg lies up against the ceiling and projects outwardly from the partition generally into the roomspace. With the member secured in this manner, the finisher spreads a layer of mortar over the vertical leg and adjacent portions of the partition in order to provide a smooth transition from the partition to the member and to fully conceal the vertical leg. In applying the mortar, the finisher may advantageously run the edge of his trowel along and abutted against the horizontal leg which protectively masks the ceiling at this time.

Abstract: An arrangement for use when casting concrete floors, particularly in locales having pillars, floor drains or the like. The arrangement includes straight concrete beams and sections of ring-like concrete beams which are intended to be incorporated in the resultant floor. The ring sections are arranged to coact in order to completely encircle a free-standing pillar or the like, or to partially encircle a pillar located adjacent a wall. The sections are provided with a lower support flange intended to support the ends of the straight beams. The height of the straight beams is so selected in relation to the height of the ring-like beams that when the straight beams rest on the aforementioned support flange, the upper surfaces of both kinds of beams are located in a common plane, on a level with the resultant floor surface, in order to be able to serve as support paths for concrete smoothing devices. The application also relates to a method for manufacturing beams intended for use with the arrangement.

Abstract: A veneer anchor for use in a dry wall construction system which anchor comprises a plate member having a vertically projecting bar portion secured thereto and disposed in substantially parallel relationship with said plate member. The plate member includes end members disposed in substantially perpendicular relationship with respect to said plate member with the end members being bifurcated and having a pronged outer end configuration. The anchor is employed to secure a wall board or insulation layer to a vertical channel or standard framing member and to thereafter maintain the structural integrity of securement of the anchor with respect to the channel or framing member, notwithstanding the ultimate shifting, deterioration or disposition of the wall board or insulation layer. Thereafter, a wall-tie is inserted between the plate member and the projecting bar portion and the wall-tie is built into the outer wythe of the wall system.

Abstract: An insulated window panel is provided with pseudo sash bar lattices that are affixed, preferably by dual-sided adhesive foam tape, in coincidental alignment to the outwardly facing transparent surfaces of the panel. Dual-and triple-glazed window panels constructed in accordance with the present invention have the appearance of being constructed of a plurality of small panes or panels that are surrounded and held in planar array by sash bars. The resemblance to French-style windows is achieved by means of a remarkable trompe l'oeil effect that results when pseudo sash bar lattices are affixed in coincidental alignment on opposite sides of the panel. Also disclosed is a novel triple-glazed insulated panel wherein the insulating peripheral seal is protected by providing a central pane with slightly reduced height and width dimensions relative to those of the two outwardly facing panes.

Abstract: A grid system for suspension ceilings is disclosed having an end connector providing an inverted, U-shaped end portion adapted to nest over the upper edge of an associated web of a runner extending through the intersection.

The end connector is mounted between opposed, parallel, vertical webs on the associated runner by tabs which extend through web slots. The separate connectors and the runners can be formed of materials having different thicknesses so that the material forming the web and the material forming the connector can be selected to provide the required strength without excessive use of materials. The connectors can be used both in main run cross-run systems, and in basket weave systems.
