A support device of technological systems for walls, provided with at least a layer of plates (2), includes: first section bar means (3), having an elongated shape, each one including a first element (4) with "C" cross section whose edges have respective folded borders, first (5) and second (6), defining a longitudinal opening (10) of section bar means (3); fixing means (7) each one provided with at least first lip means (8) and first blocking means (9). In an assemblage condition (M) of device (1), the first section bar means (3) are fit for containing and supporting connection elements (50) of the system by means of respective first elements (4) and the second folded border (6) supports the plates (2) of the wall layer. The first lip means (8) of fixing means (7) are interposed between the first folded border (5) and said plates (2) and the first blocking means (9) are fit for fixing interconnection elements (51) of technological system to respective openings of the wall layer and to longitudinal openings (10) of the first section bar means (3).

A support structure (1) is provided comprising a plurality of curved surfaces A, B hingedly interconnected along their edges such as to provide effective deployment in two separate stages. Preferably, the structure has only two curved surfaces hingedly interconnected at a single non-planar hinge line. In FIG. 1(a), the two sheets A, B are coplanar in that they lie in the same horizontal plane, permitting the structure to be in a flat, first stage deployment position. In Figure (b), the structure is fully deployed in a second stage deployment position by bringing sheet A out of plane through some angle in relation to the position of sheet B, resulting in both sheets becoming curved. The structure has utility in various space-based as well as terrestrial reflective and absorbing applications, and bears definite advantage in terms of weight saving, high stiffness and well-defined surface precision.

A device for preparing and ejecting polymeric cement made from at least two pre-packaged components comprises a tubular vessel including a first axial end wall having a closed outlet, and a second axial end wall having an aperture. A first starting component of the polymeric cement is present inside said tubular vessel near the first axial end wall. A hollow shaft extends through said aperture of the second axial end wall. A piston element comprises a closed container filled with a second starting component of the polymeric cement. The piston element is selectively lockable to the shaft. The container has a bore and is slidingly engaged upon said shaft. An agitator element is secured to one end of the shaft. Furthermore opening means for providing an opening in the closed container are provided. The hollow shaft is provided with a gas permeable filter means.

A frame structure consisting of two compound units provided with mutually facing grooves undercut on either side, in which the first compound unit can be attached in a desired position to the second compound unit via a detachable coupling which comprises a turning part which can be turned from the outside manually via a handle about its longitudinal axis by about 90 DEG into its coupling or decoupling position, and which in its coupling position positively engages by means of a T-head at its one end in one of the two grooves and by means of anchoring means at its other end in the other of the two grooves and can be locked in this coupling position by means of an anti-rotation device. To connect the two compound units to each other without special tools, but above all to be able also to detach them from each other again, it is proposed according to the invention that the anchoring means comprise a punched part which is arranged longitudinally displaceably in the one groove and bears the turning part which is freely rotatable relative to it and that the handle comprise a resilient element connected securely against rotation to the turning part, which element in decoupling position extends in relieved state or under only slight stress between the two compound units and in coupling position engages under bending stress behind a holder.

A stackable insulating foam panel which has a top side and a bottom side. Each of the panels has a median row of alternating projections and recesses with a similar complementary shape. The median row is disposed between two coplanar edge surfaces. Each projection of the top side is opposed to a recess of the bottom side whereby the top side and/or the bottom side of the panel can be interconnected with either the top side or the bottom side of a like panel. The present invention also concerns a wall form assembly which comprises opposed foam panels disposed in parallel relationship to make a wall form for receiving a flowable material such as concrete and a plurality of connectors for tying the opposed foam panels together.

A planographic printing plate precursor comprises: a support; and a recording layer disposed on the support, the recording layer comprising a lower layer and an upper layer disposed on the lower layer, wherein the lower layer contains a resin having in a main chain structure a phenol skeleton and a urea bond, the upper layer contains a water-insoluble alkali-soluble resin and an infrared absorber, and the solubility of the upper layer in an aqueous alkali solution is increased by exposure. The planographic printing plate precursor can be produced directly through scanning exposure based on digital signals. It is superior in reproducibility of highly fine images and also superior in printing durability and chemical resistance of small-area image areas such as halftone dots and thin lines.

The system has a rail (1) and a coating girdle coating longitudinally sides of the rail. The girdle rests in a groove (3) formed by a profile (2) or realized in a form of beam or concrete platform. The girdle has a lower layer (4) with a soft coating material stretching under a base of the rail to coat the base, and an upper layer (5) with a rigid coating material to coat the rail till a head of the rail.

It is structured in the form of a bearing sheet made up of a series of profiled plates (1), which run from the ground to the roof, grooved, to form trays with a U-shaped section, which are attached by their central branch to the front edge of the floor slabs and whose side branches (2) serve as supports and spacers for an exterior sheet (7), which forms the exposed face of the front wall, using modular pieces (9) that are mounted on strips (10) suitably attached to the front edge (3) of the trays (1), or panels that are directly secured to those edges if there are no strips. The respective layers (6) of insulation and soundproofing material lie at the bottom of the trays (1), which are still at a considerable distance from the exterior sheet (7), forming a ventilated chamber that also runs from the floor to the roof, while the internal face of the bearing sheet (5) adapts to the insertion of another insulating and soundproofing layer (13), an inner sheet (12), which takes the form of a self-supporting back made up of panels composed of plaster sheets on a galvanised steel structure.

A hoarding (1) comprising wall means (2) and one or more wall supports (3), in which each wall support comprises a trough (4) and a post (5) in which the trough is substantially rectangular in shape and has a first end (7) and a second end (9), and in which in use the post is disposed substantially vertically at the first end of the trough, in which in use the post carries the wall means, in which the trough is disposed behind the wall means in use and is arranged perpendicular to the wall means, and in which the trough carries ballast (6) in use.
