Abstract: Tarpaulins (sometimes termed "tarps") are used to protect an underlying structure or material from wind, rain and the other effects of the weather. Some tarpaulins are insulating in nature. Such insulating tarpaulins in the past have comprised weatherproof membranes with a plastic foam or polyester fiberfill portion between the membranes. These prior membranes have been characterized by short useful life and marginal insulating and weatherproofing ability, either because of limitations of the insulating fill (foam or fiber) or difficulty in sealing the seams or edges between adjacent tarpaulins. The disclosed tarpaulin comprises a first and second membrane sandwiching an insulating batt of a highly resilient fibrous glass insulation. The tarpaulin includes a seam structure around all four edges of the tarpaulin which not only fastens the first and second membranes together but holds the highly resilient fibrous insulating batt in position.

Abstract: An anchor device that is comprised of but two parts, a core that has a cylindrical body portion and a sleeve having an inside diameter that matches the body portion. The core has an end cap that is adapted for attachment to a power post or the like. The sleeve is positioned over the core and a restriction resists full seating of the core in the sleeve. When positioned in the hole of a concrete floor, the core is forced into the sleeve e.g., with a tool designed for that purpose. This expands the sleeve into the concrete and seats the core in the sleeve, and the combination sleeve.

Abstract: A mechanically fully isolated body (D) is connected by mechanical isolators (C), behaving elastically in all directions, with its basis (B). This basis is linked firmly to the surrounding formation. There exists a frequency range called hole of eigenfrequencies between the highest (6) of the six lowest system eigenfrequencies (1-6)--called fundamental eigenfrequencies--and the lowest (7) of all higher eigenfrequencies (7,8 . . . )--called upper eigenfrequencies--of the oscillatory element consisting of the body (D) and the isolators (C). In this range the oscillatory element presents no eigenfrequencies. The hole of eigenfrequencies shall cover the range of resonance of the relevant design response spectrum of the excitation (E). By these measures the body resists to the strongest earthquakes measured or to be expected at that site.

Abstract: The disclosure relates to scaffolding and includes the use of apertured locking discs adapted to cooperate with vertical supports, and horizontal or diagonal brace members. The ends of the brace members are provided with pivotable locking wedges which can be driven down through said ends and through the apertures in the locking discs. The apertures are all identically shaped and depending upon the intended purpose of the scaffold, certain surfaces of the ends of the brace members and the cooperating apertures are contacted by the locking wedges which thereby determines in which direction the horizontal members will extend.

Abstract: A concrete forming system includes telescoping jacks, bottom chords and top chords. The bottom and top chords separate the telescoping jacks into spaced, parallel rows. Diagonal struts extend between the bottom chords and the top chords within each row. Cross braces extend between corresponding telescoping jacks of adjacent rows. Joists are supported on the top chords and/or on beams supported by the telescoping jacks, and in turn support forming members. The component parts of the system may be used to make flying truss forms, flying pan forms, structural beam forms, rolling deck scaffold forms, column hung forms and wall forms.

Abstract: A modular dome structure constructed by using uniform Y joints which have branches forming angles of 120.degree., 120.degree. and 108.degree.. The Y joints are interconnected by uniform length members to form pentagonal and hexagonal structures. These modular structures are interconnected to form a modular dome structure which may have a pentagonal apex structure or a hexagonal apex structure. All members are made to harden after inflation due to vulcanization and curing process, so that permanent resistance to stress and strain will be provided in its final form. Due to inflatability of members, the logistic involved in actual construction will be kept minimum, and the freight cost for material transportation will be saved significantly.

Abstract: An overhanging gable structure for buildings in which the overhanging gable is supported by a series of tubular metal members which are secured within brackets that are attached to the frame of the building and disposed between the top plate of an outer wall of the building and the line of the rafters of the roof of the building.

Abstract: A sheet metal roofing system 10 comprising pan 11, bracket 21 and batten 31 sections is disclosed. The system covers a given surface 60 with a minimum amount of material while providing two mated surfaces 12 and 13 for sealing the sections together. The absence of fasteners from the exposed surfaces allows them to expand and contract in response to changing temperatures. The pans have rolled edges 15 to provide increased strength and a better fit with the brackets 21.

Abstract: A raising mechanism for drilling equipment towers mounted on a platform and having two pairs of linkage members, one shorter than the other one, each pair having its members connected on one end to each other and to the underside of the tower at spaced apart points. A cylinder is designed to vary the angle between the tower and the linkage members thereby causing the tower to move from a substantially horizontal position to a vertical position, or if desired, to a forward inclined position by the use of removable wedge elements.

Abstract: A composite section that the frames of a window or a door are made out of or that are used to construct a facade consist of a plastic rail section and of a metal rail section. The metal rail sections face inward when the composite section is employed to construct a window or a door frame, whereas the plastic rail sections constitute the outer shell. The plastic rail section has anchoring webs with free edges that engage recesses in the metal rail sections. The anchoring webs are secured in the recesses because the outer recess webs and/or inner recess webs conform to the shape of the anchoring webs. The plastic rail sections are angular in cross-section and have outer flanks that in the case of a window or door constitute motion-limiting webs or glass-securing strips. The fittings that connect the casement to the window frame and the fittings that anchor the window frame are attached only to the metal rail sections.

Abstract: A glass assembly for forming a wall or roof-light, comprises a planar array of sealed multiple glazing units which are secured to supporting members by mechanical fixings which pass through the outer glass sheets of the units outside the seals of the units. The outer glass sheets are sealed edge-to-edge.

Abstract: Disclosed is a shelter structure using a saddle-shaped cable dome system for a large-span, lightweight roof membrane. The structure uses the curvatures of a saddle surface, combined with two orthogonal cable nets separated by a set of compression struts, to create an efficient structural system confined by an edge ring loaded primarily in compression.

Abstract: An eaves troughing assembly includes elongated eaves troughing members of resilient material with generally U-shaped section having a rear portion, base portion and front portion, the front portion of each eaves troughing member having a longitudinally extending recess in a front face at least adjacent an end of the member. Elongated connectors of resilient material with generally U-shaped section have a rear connector portion having an inwardly extending upper free end portion forming a recess between the free end portion and an adjacent part of the rear connector to receive an upper end of the rear portion of an eaves troughing member. The front portion of each connector member has a longitudinally extending projection in a rear face shaped for snapping engagement in the recess of an eaves troughing member.

Abstract: A structural bearing is disclosed which comprises a bearing unit, intumescent material spaced from at least one side of the bearing unit to be protected from fire, and expanded plastics material which is of low compression strength relative to the bearing unit, adjacent to the one side of the bearing unit and disposed between the one side of the bearing unit and at least part of the intumescent material, the intumescent material being adjacent to the expanded plastics material.

Abstract: Angular sections form frames which can be fitted together in the frame plane in modular fashion. Legs of the sections are formed so that through two interconnected legs of adjacent frames notches of T-shaped cross-section result, into which hammer head-shaped ends of pull rods can be introduced. By means of the pull rods, ledges can be pressed against filter and/or light fixture housings, which in this manner are pressed against legs of the profiles on the opposite housing side, adjacent frames thus make it possible in a correspondingly compact model to attach filters and light fixtures without the distance between two adjacent filters or between a filter and a light fixture occupying a width that would impair the flow profile of the air issuing from the filters.

Abstract: A hollow building element of a plastics material comprises an upper wall, a lower wall, a pair of opposite side walls interconnecting the lateral edges of the upper and lower walls, a joining member in the form of a cylindrical, slotted, downwardly open flange provided at the upper edges of each side wall, the lower end of a side wall being integrally connected to an anchoring element for anchoring the building element to a support and the lower end of the opposite side wall being integrally connected to a guide member adapted to engage the anchoring member of an adjacent building element so as to maintain the lower ends of two adjacent side walls in spaced relationship and so as to form a tight connection between such elements.

Abstract: An anchor assembly for use in raising tilt-up wall sections which are cast in a horizontal position. The assembly includes an elongated steel anchor member supported in a vertical position on a base. A horizontal steel pin extends through an opening in the lower portion of the anchor member, with the pin and anchor member being retained in the base by two pairs of opposing resilient members which extend partially around the pin. A recess former is positioned over the upper end of the anchor member and is detachably locked to the anchor member by another pair of opposing resilient members which are extendable into a second opening in the upper portion of the anchor member. After the wall section is cast, the recess former is unlocked from the anchor member and removed from the wall section thereby providing access to the second opening of the anchor member.

Abstract: A system for interlocking the edges and corners of adjacent panels of a pedestal supported, elevated floor construction. Edge and corner clamp units are put in place after set-up of the panels. The edge clamp units include a lower elongated element which drops through a similarly shaped gap between adjacent panels and is then rotated 90.degree. out of alignment. A screw turned from the space above the floor draws the lower clamp element towards an upper clamp element to grip and interlock intervening edges of the adjacent panels. Adjacent corners of four panels are interlocked to a supporting pedestal by an overlying clamp plate. This corner clamp plate is releasably secured to the pedestal by an individual screw which is also tightened from the space above the floor.
