Abstract: A modular unit (1) of customizable color for creating load-bearing structures, photovoltaic houses, for use as a construction and/or a support for photovoltaic carpets (7). Namely, this support or modular base unit, made of extruded plastic, can act as a floor, roof, and/or lateral panel/support; furthermore, this module may be also used as a support for a photovoltaic carpet mounted thereto; thus, the photovoltaic carpet can be mounted to a plastic support instead of the usual metal support or bitumen sheets, as is typically used. This allows one-time application of the photovoltaic carpet (7), even without a thermoplastic load-bearing or containing support, by simply laying it to existing rigid surfaces over the desired areas (B8), and ensuring chemical bonding at the lateral ends, with water tightness guaranteed over time.

Abstract: A junction device (1) for hoses (2) comprises an insert (3) having a portion (3a) inserted internally to an end of a hose (2) and a bushing (9) inserted externally to said end of the hose and locked to maintain the end of the hose securely inserted between the portion (3a) of said insert and the bushing. The insert comprises an annular groove (6) interposed between the portion (3a) inserted internally to the end of the hose and a portion (3b) external to said hose, whilst the bushing (9) comprises a concave annular area (10) which, when the junction device is assembled, is positioned internally to said annular groove of the insert. The insert further comprises an annular rib (7) to provide an area of interference with the concave annular area (10) of the bushing.

Abstract: A device for automatically positioning and centering the optical head of a microscope, for example for surgical use, the optical head being connected to a drive unit. This device analyzes the image framed by the microscope objective by use of an automatic system for analyzing the image light distribution, for example a video camera connected to a processing circuit and possibly to a microprocessor, then processes the image until a reference point of the light distribution is identified by dividing the image into N subzones. Then, on the basis of information regarding the position of the reference point, the device controls the drive unit of the microscope optical head to return the reference point to within a predetermined tolerance zone, if possible.
