Abstract:
The invention relates to a structure for presses, a resistant structure of which comprises at least a resistant element (1) which, in turn, comprises an annular element or arch (2), internally of which are predisposed two facing surfaces (20), diametrically opposite one another, between which at least a power organ (5) is insertable, which power organ (5) is suitable for compressing an object or material to be pressed between two bodies, such as to unload, on the facing surfaces (20), equal and opposite reactions of the pressing action. Full-thickness cuts (3) are symmetrically arranged at ends of the facing surfaces (20), the cuts (3) having a predetermined width, each of which, starting from the end of the relative facing surface (20), develops over an arc of a polycentric curve which exhibits at least a first tract (22) the most external surface of which connects with the lateral surface (24) of the vertical portion of the annular element or arch (2), and at least a second tract (23) which is connected to the first tract (22), is shaped as an arc of a circle and extends over a portion of not less than a quarter of an arc of circumference. At least a plate (4) is housed in each full-thickness cut (3) which plate (4) is provided with opposite surfaces that are destined to come into contact with the reciprocally-facing surfaces delimiting each full-thickness cut (3).

Abstract:
A heating solar panel (1) predisposed for conversion of electromagnetic radiation of solar origin incident on an absorbent surface (14) of the solar panel (1) into heat energy in a vector fluid, comprising internal surfaces (10) which are opposite one another and define a hollow space (11) predisposed for circulation of the vector fluid, the hollow space (11) communicating with outside the heating solar panel (1) via at least a delivery opening (12) and at least a return opening (13), at least the absorbent surface (14) of the panel being uniform. The absorbent surface (14) of the panel is flat.
Abstract:
A photovoltaic module (1) comprises a plurality of photovoltaic cells (100), electrically interconnected to define a photo-active surface (2). The photovoltaic cells (100) being closed between a front covering layer (3a) and a back covering layer (3b) which are electrically insulating, the front covering layer (3 a) being frontally covered by a frontal covering element (4) having a mechanical protection function for the photovoltaic cells (100). The back covering layer (3b) being posteriorly supported by a support element, the support element being a ceramic slab of a limited thickness.
Abstract:
In a process for realising silk-screening glaze pastes in plants for decoration of ceramic objects, predetermined quantities of colorant oxides, silk- screening base and liquid elements are placed in a micronising mill (2) and micronised before being sieved to obtain the silk-screening glaze paste.
Abstract:
Each anchoring organ (1) is provided with a base (10) which is provided on a side thereof with an active surface (11) which is destined to couple with a portion of surface (2) to which the anchoring organ (1) is to be fixed, and on an opposite side thereof with means (14) for gripping the anchoring organ (1). A predetermined amount of glue (3) is predisposed on the active surface (11) or on a corresponding portion of surface (2) on which the active surface (11) is destined to be coupled, which glue (3) is activated only following subjection thereof to a mechanical action. Using the means for gripping (14) the anchoring organ (1) can be set in motion and pressed against the surface (2) in order to activate the glue (3) following the mechanical action exerted thereon.
Abstract:
The device comprises: a frame (2) prediposed to be associated to a motor vehicle, which frame (2) delimits an opening (3) of a chamber (30); a hatch (4) prdisposed to close the opening (3) delimited by the frame (2); means for moving, interpositioned between the frame (2) and the hatch (4), predisposed to activate the hatch (4) and to move the hatch (4) between at least a closed position, in which the hatch (4) closes the opening (3) delimited by the frame (2), and at least an open position, in which the hatch (4) does not close the opening (3). The means for moving are arranged in such a way as to define a plane of motion, oscillating about a main rotation axis (x), on which plane of motion the means for moving slide the batch (4) along a sliding direction (y) which is perpendicular to the main rotation axis (x). The main rotation axis (x) is transversal with respect to the opening (3) delimited by the frame (2).
Abstract:
The device comprises: a catheter (2) having a longitudinal axis (x); at least an inflatable dilating balloon (3), which is coaxial and solidly constrained to the catheter (2); a pusher element (5), solidly constrained to the catheter (2) and projecting transversally from the catheter (2); a sheath (6) in which the catheter (2) is slidably insertable, at least over a part of a length thereof.
Abstract:
The device comprises at least a support element (6) to which a plurality of projecting appendages (7) are fixed in a predetermined distribution. The support element (6) is mobile between at least a first position, in which at least ends of the projecting appendages (7) are immersed at least partially in a recipient (9) containing the glue, so that small quantities of the glue remain adhering to the ends of the projecting appendages (7) and at least a second position, in which the ends of the projecting appendages (7) are brought up to at least a surface so that at least a part of the small quantities of glue come into contact with the surface and remain deposited thereon.
