Abstract: Provided is a system of prefabricated panels couplable by a coupling device engaged in grooves with dovetail-shaped cross sections, each groove having two mutually facing steps. The coupling device has a metallic coupling element having a first and a second tapered elements with height along a vertical axis and symmetrical with respect to a first plane perpendicular to the vertical axis. A foil key rotates the coupling element from a rest position, in which each tapered element is inserted into a respective groove and free to move along the respective groove, to a locked position, in which each tapered element is inserted into the respective groove and constrained to the respective groove along the first reference plane, and vice versa. Each tapered element has a first and a second wings symmetrical with respect to a second reference plane and extending along the vertical axis with ends for engaging the steps.

Abstract: The present invention relates to a false ceiling mounting system that is simple and effective, while also allowing quick disassembly for inspection or total removal. To this end, a section bar with resilient tabs is provided, the false ceiling panel being fit between two section bars.

Abstract: The present disclosure concerns a ventilation system to be applied to a micronizer, in such a way that the ventilation does not prevent nebulization, rather it disperses it in an environment that for example is to be sterilized. Thanks to a particular configuration, the ventilation system is also resistant to water present in the environment to be sterilized.
