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.

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 device for heating or cooling multiple single chamber containers or a multi-chamber container. The device includes: a unitary heat or cold source providing a source of heat or cold; heat exchange elements in thermal communication with the heat or cold source and extending away from the heat or cold source; a thermal barrier between each of said heat exchange elements to thermally isolate the heat exchange elements from each other. Each heat exchange element is thermally associated with one or more chambers that are different from one or more chambers associated with other heat exchange elements to thermally isolate the chambers from each other. Preferably the container is a sample or reagent container used in a clinical analyzer, such as a multi-chamber reaction cuvette or a multi-chamber microtiter plate. An incubator assembly, preferably usable in a clinical analyzer, can include the device for heating or cooling.

The invention relates to a composition for producing a heat-insulating coating comprising at least one radiation-absorbing compound and at least one IR-reflector component, to a heat-insulating coating comprising this oriented, cured composition, and to a process for producing said coating.

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.

An electrical heating element comprising a resistive element consisting of granular boron carbide packed in a quartz tube embedded in a piece of copper. A first power lead is electrically connected to the boron carbide at one end of the quartz tube. This first power lead passes through and is electrically insulated from the piece of copper. The second power lead is electrically connected to the boron carbide at the other end of the quartz tube, either directly or via the piece of copper. In use, connection of the first and second leads to an electrical power source causes the resistive element to generate heat in a very fast manner and to trandmit this heat to the piece of copper.
