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.

The invention relates to a heat exchanger for motorized vehicles, comprising: at least one heat-conducting conduit for passage of a first medium, a covering of a thermally conducting porous structure connected to an external side of the conduit for passage of a second medium surrounding the conduit.

The floor part has intermediate parts (3) that connect a bottom plate and a top plate (2a). The intermediate parts are continuous in two directions that are transverse to each other, for defining girders with the plates for bearing span in both directions. The intermediate parts define passages for connecting the cavities defined by girders, with each other in one direction. Independent claims are also included for the following: (a) a building having a floor built up from concrete floor parts (b) a method for manufacturing a concrete floor part.

1. A contruction element for heat insulation in buildings, especially in protruding cantilever wall portions, comprising an elongate insulation element (10) made of a thermally insulating material, wherein elongate metallic reinforcing elements (20) are provided which extend substantially transversely for the insulation element (10) and which protrude in lateral direction on either side, characterized in that the insulation element (10), together with said reinforcing elements (20), is formed as an integral prefabricated element and provided, or adapted to be provided, with at least one compression element (30) being integrated into the insulation element (10) as an interconnecting (joining) core member and having dimensions corresponding to those of the insulation element (10).

A washable floor mat has a tufted pile textile layer ( 1 ) and an elastomer backing layer ( 2 ). The textile layer ( 1 ) includes tufts containing cotton fibres, and the backing layer ( 2 ) is made of a foamed elastomer material and includes a plurality of cleats ( 4 ) on a lower surface if the backing layer.

The invention relates to an air-cooled combustion chamber wall for combustion furnaces. The combustion chamber wall comprises at least one masonry wall with a space in the middle for the passage of cooling air along the side of the wall away from the combustion chamber side. To create a simple, stable and effective structure, the invention proposes that the masonry be made of bricks, whose walls enclose at least one air duct.

A device that may be applied in particular to shutters and similar and that will allow, by means of the rotation of the sole handle (28), the opening of the shutter, the orientation of movable blades (6) and the determination of the blocking in a plurality of different positions by moving rods (18) with the possibility of different interposition of metal plates (55, 56, 63, 66, 66 min ). In variants, i.e. the case of shutters with fix blades (6), the same handle (28) may be used for the sole opening of the shutter, while in the case of fix shutters with movable blades (6) said handle (28) may be used for the sole orientation of blades.

The invention relates to a cooling system, with a cooler (1) taking up heat, for a permanently-energized synchronous motor, in particular, a motor for a locomotive. A first line (2) leads from the output of the cooler (1) to the input of a recirculation cooler (4), emitting heat to the environment. A second line (5) leads from the output of the recirculation cooler (4) to the input of the cooler (1). A first non-return valve (3), permitting flow towards the recirculation cooler (4), is arranged in the first line (2) and a second non-return valve (7), permitting flow towards the cooler (1), is arranged in the second line (5).

A heat exchanger of a ventilating system includes: heat exchange plates having first air passage through which indoor air being discharged to outside of a building passes and a second air passage through which outdoor air being introduced to the interior of the building passes which are sequentially formed: first corrugation plates attached to the first air passage; and second corrugation plates attached to the second air passage, wherein the heat exchange plates are made of a paper material with numerous fine holes that are able to generate a capillary phenomenon and loess which radiates far infrared ray. Heat exchange and moisture exchange between the indoor air and the outdoor air are performed simultaneously, and a cleaning function of removing a harmful material contained in outdoor air can be carried out.

A method of manufacturing a composite, prestressed wooden beam (1, 10, 35, 67, 90) comprising the steps of: positioning a plurality of beam parts (2, 16, 68, 69) in contact with one another at least in one direction transverse of the direction of length, bending the beam parts (2, 16, 68, 69) into the desired shape and interconnecting the beam parts (2, 26, 68, 69). The number of beam parts (2, 16, 68, 69) positioned in mutual contact is bent integrally into the desired shape and retained. Subsequently the connection is performed by passing a great number of smooth, substantially cylindrical pins (6, 21, 61, 70, 72) through the beam parts (2, 16, 68, 69) in a direction transverse of the direction of length and subsequently the resultant composite beam (1, 35, 67, 90) is disengaged. Furthermore the invention relates to a device for manufacturing said composite, prestressed wooden beam (1, 10, 35, 67, 90) comprising a stationary, elongate gauge (11, 31). This device comprises a displaceable drilling device (17, 37) comprising a drill holder (26, 51) having a rotary shaft to be positioned transversely of the direction of length of the gauge (11, 31), a displaceable pressing device (22, 40) having a pressing stroke transverse of the direction of length of the gauge (11, 31) and supporting means (12, 24, 32, 91) for supporting the pressing device (22, 40) with respect to the gauge (11, 31).
