Abstract: The casing for the electric motor is formed, at least partially, by a series of rings joined together, for example through braze welding. The rings have slots that, when the rings are installed and joined together, define one or more cooling channels for a coolant to flow. An electric motor is also disclosed, comprising a casing of this kind, as well as a method for producing the casing.

Abstract: In a motorcycle with fairing (1), to facilitate the inflow of air from the front into the fairing (21), a front opening (23) is provided in the front portion of the fairing (21). The front opening (23) has a smaller extension in vertical direction with respect to the fairing itself, so that the upper area of the front portion of fairing is open to allow the direct inflow of an air flow (F) generated by the forward movement of the motorcycle (1). Vice versa, the lower area of the front portion of the fairing (21) is closed by a covering (31) which forms an aerodynamic profile with a front outer surface (31a) and a rear inner surface (31b), which divides a descending flow of air into an outer partial flow (FA) and an inner partial flow (FB).

Abstract: The plant for producing a corrugated board comprises one or more single facers and a double facer, as well as respective unwinders for unwinding reels of paper webs. Arranged along the production line, in suitable positions, are thermographic cameras which acquire images through which it is possible to trace the various characteristics of the cardboard, for example the moisture content thereof, detect manufacturing defects, after which it is possible to intervene on one or more process parameters so as to eliminate the causes of the defects.

Abstract: The protection system (5) comprises a first tubular member (13) and a second tubular member (15) which can be slidably inserted into each other and a protection (8) at one end of the first tubular member (13). The protection comprises a protective boot (40) and a first annular element (21) fixed to the first tubular member (13). Further provided for is a second annular element (33) which can be torsionally coupled to the first annular element (21) and which can be decoupled therefrom by means of a mutual movement between the first annular element (21) and the second annular element (33) in a direction approximately parallel to the axis (A-A) of the first tubular member (13). The second annular element (33) is coupled to the protective boot (40) which is provided with members (49) for coupling to a stationary plate (51) which can be connected to a power take-off (9). A drive shaft provided with such a protection system is also described.

Abstract: The clutch (1) comprises a housing (3) connected to a drive input member(5). First friction discs (7) are mounted in the housing (3) and rotate therewith. Second friction discs (9) are mounted on a driven member (11). A pressure plate (13) is elastically stressed toward the driven member (11) to compress the first and the5second friction discs (7, 9) against one another. Cam profiles (31, 33) integral with the driven member (11) and with the pressure plate (13), generate a thrust to move the driven member and pressure plate away from each other when it is necessary to reduce the pressure exerted by the pressure plate (13) on the first and second friction discs (7, 9). An angular stroke limiter limits the relative rotation between the driven 10member (11) and the pressure plate (13) and thereby limits the movement of thepressure plate (13) away from the driven member (11).

Abstract: The device comprises a laser source (7) adapted to emit a laser radiation at a wave- length between around 620 nm and around 750 nm, and a handpiece (5). The handpiece in turn comprises an applicator (11) with a contact surface with the epidermis defining a window (11.1) for the passage of a laser beam (F) toward the epidermis (E) of a subject to be treated. A waveguide (10) conveys the laser radiation from the laser source (7) to a scanning system (17) of the handpiece.

Abstract: For bonding together two or more plies of cellulose fibers, the plies are fed to a lamination nip between a ply-bonding rotating element and an anvil element. The ply-bonding rotating element has rollers with a cylindrical surface provided with small protuberances co-acting with larger protuberances provided on a cylindrical surface of the anvil rotating element. The plies are bonded, if necessary with the aid of a functional fluid, not containing adhesive, due to the effect of the pressure between the protuberances.
