Abstract: The invention herein teaches a crown system for kilns and furnaces for the high temperature firing of materials. One method used in the industry for a crown system consists of supporting layers of insulation with inverted T-rails attached to bones which are further attached to hanger devices hanging from pipes that rest upon an ultimate support system. To overcome the numerous problems associated with the prior art the following considerable modifications have been made: 1) slotting each inverted T-rail, along its narrow attaching flange and adding stops to each side of said slot such that the bone is evenly spaced along the T-rail when inserted and slid into position, 2) fitting rigid insulation cases fully between the bones and adjacent layers of insulation and 3) said insulation cases and said T-rail stops combine to lock said bones in position.

Abstract: A pair of parallel safety bars are track-mounted above the stairs of a stairway. The safety bars are formed so as to be gripped by the user in ascending or descending the stairs. The user steps between the bars, with each bar being hinged to permit such access, and grabs the bar in the direction of ascent or descent. The track-mounted end of the bar is pivotally connected to a shoe which slides in the track as the person moves on the bar downwardly on the bar or the weight of the user pulls the bar downwardly, friction braking elements on the shoe and in the track are contactingly engaged to restrict further movement of the bar thereby preventing the user from falling down the stairs.

Abstract: A structure of a fireproof frame for building opening portions wherein a groove is formed over the entire circumference of a wood frame, which is disposed to a building opening portion, at the surface abutted against an opening member. A non-combustible heat forming sealing material is filled in the groove and the surface of the sealing material is covered with a thin film, which is excellent in heat conductivity, by means of the self bondability of said sealing material.

Abstract: An adjustable door jamb assembly which can be simply and accurately aligned and installed in a door opening. The jamb assemblies are each made up of a fixed section and an adjustable section. Each fixed section has a plurality of snap-in guide clips supported thereon. The clips each have a plate-like body with a leg at each end and an integral cantilever tongue extending generally parallel to, but converging toward, the plate-like body of the clip so that the tongue is deflected away from the plate-like body. A flange on the adjustable section is received between the cantilever tongue and one of the legs. The tongue of each clip frictionally engages the adjustable section holding it in adjusted position on the door jamb.

Abstract: A unique wall panel is constructed from expanded polystyrene beads in an expanded polystyrene mold with structural members embedded in it during the molding process. The structural members are in the form of two by four studs placed at sixteen inch centers. Adjacent panels have interlocking grooves and ridges which fit together. The advantage of the present invention is that a total insulated wall is created with no cracks or spaces in the insulation. These lightweight panels can be carried to the building site, where base and top plates are applied and the panels interlocked to form a perfectly insulated wall.

Abstract: In the fields of mechanical engineering and toolmaking there is a frequent requirement for light but very strong constructional elements of high flexural strength, particularly as constructional components with minimum flexure despite unsupported free lengths. In the case of measurement instruments, for example, there is the problem that the rail (1) must, if possible, suffer no flexure even if used completely unsupported and with external forces acting upon it, if the reading is not to be incorrect. To this end, a constructional element in accordance with the invention with a plurality of bodies (2) made of, for example, ceramics which are connected using prestressing devices (3) or adhesives to form a rigid constructional component is presented. This structure prevents the ceramic elements from fracturing as a result of excessive bending moments since they can tilt or slide relative to each other.

Abstract: In order to provide a thermal insulation material as insulating and sealing layer for roof areas which can be used as sole roofing element for the roof areas, which can be applied on larger areas at a time and in which the disadvantages of the known solution such as the formation of buckling wrinkles and blistering are avoidable, a thermal insulation material is provided as insulating and sealing layer for roof areas which makes it possible to cover larger areas of several square meters at a time, comprising strips of insulation material bonded onto a substrate web, in which case the strips of insulation material (120) are bonded onto a suitable sheet web as a sealing layer (130) in such a way that the thermal insulation material is constructed as insulating and sealing layer so that, when it is laid, it will not be necessary to lay an additional sealing layer.

Abstract: A tie anchor for sandwich panels of reinforced concrete is formed as a flat strap. The reinforced concrete sandwich panel is formed by placing a plurality of tie members vertically in the bottom of a horizontal form with reinforcing rods extending through holes in the ends of the ties adjacent to cross-feet. A network or grid of reinforcing steel is supported from a chair provided by the ties and cross-feet and the concrete for the first layer of the panel is poured about the ties, cross-feet and reinforcing steel grid. A layer of rigid insulation material is placed on top of the first layer of wet concrete about the projecting tie members immediately after pouring the first layer of concrete and a second grid of reinforcing steel rods is supported from the holes in the projecting upper ends of the tie members. The second layer of concrete may be immediately poured about the upper end of the tie members and reinforcing steel.

Optional gasket means and insulative batt enhance the versatility of the device.

Abstract: A lightweight, high strength moldable structure is comprised of a core having a plurality of interconnected cavities. Each solid-walled cavity has a hexagonal base so that the core of the structure has upper and lower surfaces. Each solid-walled cavity has a unique tetrahexagonal shape in which a regular tetrahedron is located on top of and integrated with a hexagonal base. The walls of the cavities may be solid or they may be defined by a series of support struts for an even lighter weight structure. The upper and lower surfaces may be covered by skins, making it suitable for boat hulls, vacuum chambers, and aircraft. The hexagonal bases of the solid walled cavities may be replaced by perpendicular support walls extending between the adjacent tetrahedral apices and/or hexagonal base vertices.

More particularly, the invention relates to elongated roof gutter sections which include a bottom member and a front wall and a rear wall attached lengthwise along the member's opposite edges thereby forming a channel. The gutter sections further include an overhanging lip consisting of the bottom member and protruding away from the channel at either end of the channel. The elongated roof gutter sections are removably mounted using a hook and slot, or an interlocking flange system to an elongated fastener member which, in turn, is mounted along the roof line of a building.

Abstract: A trim system for a wall panel system including first and second panels each having upper, lower and opposite side edges and opposite faces, the panels being connected with respective side edges located adjacent to each other. The trim system includes edge caps for mounting on the panel upper and side edges and includes a plurality of intersection caps adapted for joining the edge caps at panel intersections. The intersection caps have configurations which correspond to various configurations of the panel intersections, such as right angle, three-way tee, four-way cross and obtuse angle. A method of trimming a wall system includes the steps of placing panels in configurations with respective panel side edges adjacent to each other, inserting edge caps into intersection caps, placing the intersection caps over the panel intersections, placing the edge caps over the panel edges, and snapping the panel edge caps into releasable engagement with the panel edges.
