Abstract: One sheet section edge is bent to form two edge portions making a U shape with the sheet. The second sheet section has the adjacent edge bent to form two portions which lie adjacent the two edge portions of the first sheet section, a third portion formed by a 180.degree. bend and an additional bend to engage the inside of the U.

Abstract: Hollow, generally rectilinear structures having a top, a bottom, sides and ends can be constructed so as to be capable of being manipulated between a "normal" or unfolded type configuration and a collapsed or folded configuration in which the ends extend generally parallel to and beneath the top and in which the sides are folded so as to be located next to the ends generally between the bottom and the top. Such a structure includes hinges connecting the ends to the top so that they can be pivoted so as to lie generally parallel to the top. Such a structure also includes a frame or frame-type elements forming a part of the top and extending adjacent to the ends when the ends are folded into such a collapsed position.

Abstract: In a building construction having adjacent wall panel sections which are joined together at an exterior angle exceeding 180 degrees, an improved means is provided for supporting and joining the wall sections. A metallic channel member forms a portion of the joining edge of each wall section. Each channel member has one side wall which is bent inwardly towards its base section, and this inwardly bent side wall is secured underneath the exterior panel member so that the base section of the channel member in cooperation with the joining edge of the exterior panel member forms a substantially continuous joining surface.

Abstract: A fascia board support comprises an angled piece of metal having a generally horizontal flange and a depending panel. A slit is provided in the panel which permits the horizontal flange to be bent and the central portion of the panel to overlap. In use, the support is placed on the exposed, squared end of a rafter. The flange is bent to provide a vertical part of the end of the rafter. The central portions of the panel become overlapped. The support is nailed to the rafter through holes in the overlapping portions. An index on the support permits the flange to be accurately bent for use with roofs of various pitches. The vertical part of the flange receives the fascia board, as by nailing.

Abstract: An acoustical panel formed of a core of sound-attenuating material having a front and a back surface. The edges of the core are resin-hardened for rigidification. The core is covered by a fabric stretched over its front surface adhered to the hardened edges and to the back surface. A board cover is fixed on the back surface over the core and the ends of the fabric.In other versions of the invention, the core is reinforced by having its edges encased in a frame to which it is secured by the resin. The fabric is stretched over the frame and core thereby forming an air gap between the fabric and the core which improves the acoustical efficiency of the panel and masks the outline of the frame. High-impact-resistant channel members of different shapes constitute the frame.

Abstract: An insulated log building structure comprising two parallel, vertically extending log walls having an insulative layer of foam plastic disposed therebetween. Each of the walls are formed of horizontally extending logs mounted vertically upon one another in a tongue and groove relationship. A layer of fiberglass insulation may be disposed between the tongues and grooves of contacting logs to insulatively seal the joints. Vertically extending tie rods within vertically aligned apertures of the logs making up the walls hold the two log walls in parallel alignment.

Abstract: In an articulated boom having a platform and comprised of upper and lower booms respectively, there are hydraulic actuators controlling the movements of the upper and lower booms. Control means are necessary in association with the lower boom to control its rate of movement, slowing such rate of movement as the lower boom approaches its retracted, or full rest, position. A position responsive valve permits unimpeded fluid pressure access to the actuator for lowering the lower boom at its regular rate until the lower boom reaches a critical angle as it approaches horizontal position, at which time the valve prevents further fluid access to its associated hydraulic actuator. Thereafter, a position responsive valve and a pressure reducing valve reduce the rate of descent of the lower boom until the lower boom is fully retracted to its rest position.

Abstract: A multi-dwelling structure is disclosed in which dwellings are arranged on terraces. The structure may be constructed on steep hill sides, or a hill may be built up from earth brought to the site. Preferably, one of the walls of the dwellings is formed of rigid upright panels with pliable reinforcing members secured to the panels and extending rearwardly into the earth to consolidate the earth particles. In the alternative, one of the walls of the dwellings may be formed of concrete cast in situ. The arrangement of the dwellings in the structure provides privacy and extensive areas for growing plants and trees.

Abstract: Building construction from modules of inverted U shape a full story high with a span of 10 to 30 feet and a depth of 2 to 6 feet. The modules may be monolithic such as of reenforced concrete or plastic foam, or may be of light weight hollow metal construction, assembled together with partitions and end panels. Cast modules can be cast between thin previously formed sheets held by framework to form casting mold, the sheets becoming surfaces of the module.

Abstract: According to the present invention, a slatted floor system comprises a plurality of elongated, spaced, generally parallel slats. Each slat has a top, load-carrying surface with spaced apart, opposite outer edges; a bottom surface substantially parallel to the top surface; and a pair of side surfaces integral with the top surface and the bottom surface. The side surfaces are joined with the top surface along lines recessed from the outer edges of the top surface. The side surfaces further taper toward each other in first portions, adjacent the top surface, then extend substantially parallel to each other and vertically relative to the bottom surface in second portions, thereby forming with the top and bottom surfaces a generally Y-shaped, enclosed main compartment.

Abstract: A bracket for mounting an electrical outlet box on vertical metal studs in a building or the like structure. The bracket including a channel shaped sheet metal element adapted to be clamped on and affixed to the vertical metal stud. The clamping element, including a pair of arms spaced apart by means of a web and one of said arms, is doubled back or lapped on itself and spotwelded or otherwise affixed to the arm. Welded or otherwise affixed to the doubled back portion of the arm laterally extends a member provided with an opening therein beyond which extends a solid portion. The opening receives a standard electrical plaster or dry wall ring with is joined to a standard electrical outlet box by screws. The dry wall ring is provided with open-ended slots therein through which the screws extend and are threaded into the outlet box, the position of the outlet box relative to the dry wall ring being adjustable by merely sliding the screws out of the open-ended slots in the dry wall ring.
