摘要:
A modular spiral staircase, comprising a central support pole (2) and a plurality of steps (3) fixed to said pole (2) at different heights and in different angular positions with reference to the axis of said pole (2) so as to be arranged according to a helix; the central pole (2) comprises a plurality of plate-shaped elements (4) of the same shape, assembled on top of one another and angularly offset with respect to one another by a certain predetermined angle (a) with respect to the axis of said central pole (2) so as to define a substantially helical shape. The staircase moreover comprises connection means (6) for connecting each of said plate-shaped elements (4) to the elements (4) immediately above and below. The connection means (6) comprise a plurality of slotted openings (7,8) foreseen in each of said plate-shaped elements (4), and a plurality of axial fixing elements (9) inserted through said slotted openings (7,8).

摘要:
A module for the dimensional analysis of a plate-holding cylinder, comprising a plurality of boxes (2,3), in table form, each of which corresponds to a surface portion (110) of the outer surface (105) of the plate-holding cylinder (104) and is indicative of the dimensional deviation of said surface portion (110) with respect to the nominal diameter of the plate-holding cylinder (104). A process and an apparatus (100) for dimensional analysis of the plate-holding cylinder (104) are also proposed.
摘要:
Intercom set (1), of the type comprising at least one external signal transceiver unit (2), of the type selected among wired units and remotely operated units, which is arranged outside a building (A), and at least one internal signal transceiver unit (3), of the type selected among wired units and remotely operated units, which is arranged inside a respective building unit, apartment (B), which is present in the building (A); at least one internal unit (3) comprising at least one respective control element (4) for sending an alarm signal; the at least one external unit (2) and the at least one internal unit (3) comprising at least one deterrent device (5), which is selected among a loudspeaker and a visual indicator, designed to emit an alarm signal.
摘要:
Catheter (1), comprising a first proximal cannula (3) and a second proximal cannula (3'), for connection to blood lines of machines for haemodialysis or similar, respectively affected by a first lumen (4) and by a second lumen (4') for the passage of blood and medical fluids, and pressurised release means (5,5';5) arranged in communication with said first lumen (4) and/or said second lumen (4') for the controlled dispensing of an anti-coagulant fluid in the periods between one treatment and another, so as to prevent the formation of occlusions in the catheter (1), the pressurised release means (5,5';5) comprising an elastomeric pump (6) contained inside a rigid casing (8), said casing (8) being able to be removably associated, at a first opening (9a) for dispensing the anti-coagulant fluid, with said first cannula (3) and/or with said second cannula (3') through a first quick connection element (3a) and/or a second quick connection element (3b). The casing (8) comprises a second opening (10a) for filling said elastomeric pump (6) with anti-coagulant fluid, at which there is a respective quick-fastening closing cap (10c).
摘要:
A device for reducing the content of polluting and/or unwanted substances in water, including a support made of polymeric material for a catalyst of the reaction of degradation of inorganic salts into gaseous substances; the catalyst, intended to reduce the energy required for the activation of the reaction and to accelerate its course, is an enzyme preferably selected from the group of lyases, and even more preferably selected from the subgroup of carbonic anhydrases. The inorganic are being carbonates, and/or hydrogen carbonates of calcium and/or magnesium, the reaction being the reaction of decarboxylation and acting for the conversion of inorganic salts into carbon dioxide and water according to the following reaction: HCO3−+H+H2O+CO2.
摘要:
A palletizer machine and a method of palletizing layers (2), one on top of the other, of packs (1) fed from a infeed transfer line (3) comprising a transfer unit (G1) for transferring single packs (1) arriving from the line (3) to a first operating position (P1), a forming unit (G2) for feeding single packs (1) from the position (P1) to a predefined position (P2) and the forming of layers (2) of packs (1) on a loading platform(5); a loading unit (G3) for transferring a layer (2) formed on a loading platform (5) to a pick-up station (6), and means (4) for picking up the layer (2) from the pick-up station and forming a palletized load (7) of layers (2) one on top of the other.
