Abstract:
The present invention relates to an apparatus for compacting (10) a web (N) of flexible fiber-based or filament-based material. The apparatus (10) includes at least one pair of superimposed plates (11), whose facing surfaces (11 a, 11 b) create therebetween at least one compaction space (12). The apparatus is fed with the continuous web (N), that is moved through said at least one space (12), so as to be subjected to compaction by the closure of the plates, actuated by thrust means (25). Moreover, the invention relates to a method for compacting webs (N) of flexible fiber-based or filament-based materials.
Abstract:
A fire barrier door (PO), with a vertical or horizontal opening, characterized in that it is constructed with fireproof materials joined by components which progressively dissolve in the case of fire, leaving the fireproof materials in position and with fireproof capacities suitable for maintaining the fire diffusion barrier for certain periods of time.
Abstract:
Device (100) and process for continuous indigo dyeing of warp yarns (3) or fabrics, equipped with a first hermetically sealed dyeing compartment (1), suitable for containing the dye bath, and a hermetically sealed fixing/dehydration compartment (2) of the yarn (3) or fabric. The dyeing and fixing/dehydration compartments (1, 2) comprise an inert environment and are functionally and hermetically connected with each other and there are means (4) for introducing nitrogen and/or deoxygenated air inside the same compartments; inside the fixing/dehydration compartment (2) there is at least one means (5) for directly heating and/or dehydrating the yarn (3) or fabric.
Abstract:
A cutting unit with modular structure, comprising a machine (10) , shaped with one or more bridges (11) and managed by a numeric control management software, which can use one or more respective cutting heads (15) , suitable for moving in two or three dimensions and angularly in space, so as to carry out multiple processing operations and types of cut, such as water jet or hydroabrasive cutting, laser cutting and/or plasma cutting and/or oxycutting and/or "milling" chip removal; the machine (10) in question, thanks to the particular design in modules (26) and/ or to one or more opposite working bridges (11) , allows the maximum flexibility and personalisation, according to the client's requirements .
Abstract:
A hydraulic drive system for fire stop gates, comprising an actuator device or group (AT) adapted for the opening of the fire stop gate, while the closing is controlled by means of a compensated deceleration valve (VRC1) which permits closing the gate at a minimum constant speed in case of alarm and/or with the absence of mains power supply, while maintaining all of the standard operating characteristics of the gate, even in the case wherein the same is automatised.
Abstract:
The present invention relates to a mixture of sterile and apyrogenic gases based on CO 2 and O 2 suitable for producing microbubbles which can be used in the medical, phlebological and diagnostic field. The gas mix allows stable and physiologically acceptable microbubbles to be formed, by means of more standardized procedures which are easy to effect.
Abstract:
A control system (SC) of dissipated power for electrical equipment and, in particular, for household appliances (E1, E2, E3) comprises, in a first embodiment, a switch (I, I1, I2), suitable for suitably selecting the resistive loads (R1, R2, R3, R, RP) assembled in series in household appliances, so as to dissipate half or all of the power available during their functioning; in alternative embodiments, a control circuit (CC) is used, which controls the intervention of an electronic regulation device (T) for controlling the absorption of current on the load (R) of the household appliance, if a programmable threshold of dissipated current is exceeded. The control system (SC) described can be assembled in series in household appliances at the moment of assembly, it can be installed in the plug of the household appliance or it can be used as an accessory for household appliances already connected to an electrical consumption point (UT).
Abstract:
Multistage centrifugal compressor having a tank which can be opened horizontally, comprising a lower semi-tank (11) and an upper semi-tank (12), a shaft 13 having a series of rotors 14 and a series of stages (10) each of which comprising, in turn, a series of lower semi-diaphragms 16 and a series of upper semi-diaphragms 18, a lower halfring (21) and an upper half-ring (22) which can be coupled to form a bearing ring, the lower half-ring (21) being fastened internally to the lower semi-tank (11), and the corresponding upper half-ring (22) being fastened to the upper semi-tank (12), in each stage (10) of the multistage centrifugal compressor, the lower semi-diaphragms 16 are rigidly constrained to one another by blocking means, to form a first pile (41) of lower semi-diaphragms (16) and, the corresponding upper semi-diaphragms (18) are rigidly constrained to one another by blocking means, to form a second pile (42) of lower semi-diaphragms (16), the first pile (41) can be constrained to the lower half-ring (21) and the second pile (42) can be constrained to the upper half-ring (22).
Abstract:
A manufacturing method for obtaining high-temperature components (10) for gas turbines, which comprises at least incorporation of an element or insert (14) in a main body (12) of the component (10), this element or insert (14) having mechanical properties able to withstand stresses to which said component (10) is subject in a zone where the said element or insert (14) is arranged; the invention also relates to a high temperature component thus obtained.
Abstract:
