摘要:
On a mobile rest plane on which tiles are translated in a predetermined direction, the following operate: a matrix-bearing cylinder, mobile in rotation about an axis thereof, and at least a doctor predisposed to operate contactingly with an external surface of the cylinder. The apparatus comprises: a vertically-developing frame; a first slide constrained on the vertical frame and slidable vertically with respect thereto; the matrix-bearing cylinder being supported on the first slide, together with organs for supporting the matrix-bearing cylinder and organs for controlling rotation thereof about a rotation axis thereof; a second slide, with at least one doctor being supported thereon, together with organs for supporting the doctor and organs for controlling movements thereof, is constrained on the frame and can slide vertically with respect thereto. An electrically-activated maneuvering screw produces relative positioning of the first slide and the second slide and positioning of the slides with respect to the vertically-developing frame.

A plant for storing products including at least a pair of vertical stores (40) facing one another, each being provided with opposite flanks (4) which are provided with pluralities of guides (6) located such that a pair of opposite guides which face one another on the same horizontal plane define end rests for single drawers or trays (5). Housings for the drawers or trays are defined between the pairs of guides and the contiguous pairs of guides, each of which is transferable between a load/unload configuration of the products and a storage configuration in which the drawer or tray is inserted with ends thereof on a pair of opposite guides and vice versa. An elevator (9) is provided, mobile along a development direction (A) of the vertical stores such as to move the drawers or trays. The opposite flanks of the stores are provided with profiled uprights (4a).
摘要:
A structure for presses, a resistant structure of which includes at least a resistant element which, in turn, includes an annular element or arch, internally of which are predisposed two facing surfaces, between which at least a power organ is insertable, which power organ is suitable for compressing an object or material to be pressed between two bodies. Full-thickness cuts are symmetrically arranged at ends of the facing surfaces, each cut, starting from the end of the relative facing surface, develops over an arc of a polycentric curve which exhibits at least a first tract, the most external surface of which connects with the lateral surface of the vertical portion of the annular element or arch, and at least a second tract which is connected to the first tract and extends over a portion of not less than a quarter of an arc of circumference.

An apparatus for distributing powders on a support in a predetermined pattern, includes: a belt conveyor (2) for transporting the support (3); a head for applying the powders (1), located above the conveyor (2), which head (1) includes a ring-wound closed continuous belt (4) exhibiting a plurality of perforations arranged according to a predetermined pattern, the perforations being of a size which enables passage of predetermined quantities of powders; a mechanism for controlling a supply and delivery of powders through the perforations and for keeping the continuous belt (4) clean. The head also includes a mechanism for controlling a movement of the continuous belt (4) in synchrony with a movement of the conveyor (2).

The supporting structure coverable with a plurality of concentric layers of elastic silicone-based material to produce rollers having a mirror-finished flexible outer surface has a hollow cylindrical body and a surface that is affected by a plurality of openings which are variously distributed and sized to allow the passage, produced by centrifugal force, of the material in the fluid/semifluid state from the inside towards the outer surface and to provide subsequent engagement.
摘要:
The invention comprises a mobile rest plane for tiles on which operates a matrix cylinder provided with an elastically deformable peripheral part having a smooth external skin made of an elastomer material, on which a matrix, in the form of microscopic cavities, is cut. A doctor, arranged in order to be in contact with the skin, has the task of scraping away excess glaze and any impurities deposited on the skin as well as the task of remixing the glaze such as at least partially to replenish the cavities with freshened glaze. The matrix cylinder is positioned on the rest plane such as to roll thereon without dragging on a tile upper surface as the tile transits on the rest plane.

摘要:
On a mobile rest plane, the following operate: a matrix-bearing cylinder, rotatable about an axis thereof, and at least a doctor predisposed to operate contactingly with an external surface of the matrix-bearing cylinder. A supply of glaze is directed into a chamber delimited between the doctor and a portion of external cylindrical surface of the cylinder facing the doctor, at a position in which the doctor and the surface are in contact, via a flexible conduit terminating at a discharge end thereof which is positioned superiorly of the chamber and which is commanded to perform an alternating motion. The flexible conduit is supported by an articulated chain which is commanded to slide axially in two directions along a guide.

A plant for storing products comprising at least a pair of vertical stores (40) facing one another, each being provided with opposite flanks (4) which are provided with pluralities of guides (6) located such that a pair of opposite guides (6) which face one another on the same horizontal plane define end rests for single drawers or trays (5). Housings for the drawers or trays (5) are defined between the pairs of guides (6) and the contiguous pairs of guides, each of which is transferable between a load/unload configuration of the products and a storage configuration in which the drawer or tray (5) is inserted with ends thereof on a pair of opposite guides (6) and vice versa. An elevator (9) is provided, associated to the frame (2) and mobile along a development direction (A) of the vertical stores (40) such as to move the drawers or trays (5). The opposite flanks (4) of the stores (40) are provided with profiled uprights (4a), situated on the side facing towards the zone occupied by the elevator (9), which are conformed such as to be associated to the ends of the frame of the said elevator (9) such as to realise a sliding coupling in a parallel direction to the profiled uprights (4a) and maintaining the two profiled uprights (4a) and the relative opposite flanks (4) of each store (40) at a predetermined distance.
摘要:
A process for series connection of two photovoltaic cells (1a, 1b) in series, comprising following stages: predisposing a first photovoltaic cell (1a) and a second photovoltaic cell (1b), both of a type comprising a photosensitive semiconductor layer (2) provided with front contacts (3a, 3b) and back contacts (4) arranged on opposite surfaces of the cell; partially superposing the two photovoltaic cells (1a, 1b), causing at least a partial superposing of the back contact (4) of the first photovoltaic cell (1a) on the front contact (3a, 3b) of the second photovoltaic cell (1b) and consequently establishing an electrical contact between the back contact (4) and the front contact (3a, 3b).
