  • Patent number: 6854390
    Abstract: A device in flexographic machines, for making an adjustment between an inner shaft and an extractable jacket, with the double purpose of supporting the jacket along the entire length of the shaft, and of increasing the stiffness of the jacket. The adapter comprises at each of its end portions a rigid ring, and these end rings are internally connected the one another by a first rigid cylindrical member which is thin and capable of expansion and is intended to rest against the shaft, and they are externally connected the one another by a second rigid cylindrical member intended to receive the jacket; expansion means are provided in order to secure said end rings to the shaft, and openings are provided in said second external member in order to allow blowing compressed air intended to make easier the insertion and the extraction of the jacket.

  • Patent number: 6698170
    Abstract: A combined mowing machine includes a main chassis designed to be coupled to a tractor, and a plurality of cutting units connected in such a way that they can oscillate on the chassis. Each set of cutting units has a plate support beam mounted between a pair of end plates fixed to the chassis, and a pin integral with the beam. The pin slides in two slots cut into the end plates to allow the movements of the cutting unit. The mowing machine allows the cutting units to oscillate freely in order to follow the lie of the land, as a result of the double-joint oscillation and the forward/back oscillation in the slots.

  • Patent number: 6169558
    Abstract: A laser printing process using a rotary light sensitive roller electrically charged by points by a laser beam and intended for receiving onto the charged points particles of a toner powder and then transferring the same onto a band to be printed, includes a first step wherein the image to be printed is stored, by a first laser beam coming from a first laser source controlled by a computer, onto a rotary memory roller whose surface is covered with a layer of a material capable of assuming either an amorphous or a crystalline structure, this structure being convertible under the action of a laser beam, and this material showing a high difference in reflecting ability according to whether it assumes the one or the other of its structures, and includes a second step wherein the thus stored image is transferred, by the optical reflection of a second laser beam coming from a second laser source having in its whole a linear character, onto the light sensitive roller intended to receive the toner and to transfer the

  • Patent number: 5690180
    Abstract: A horizontal-axis cutter for soil cultivation of the type comprising a horizontal-axis rotor (2) fitted with a number of blades and a gear motor (4), connected on one side to the power take-off of the tractor and on the other to the rotor, in which the gear motor is located in the front part of the machine, forward of a vertical axis A--A passing through the rotor axis.The cutter includes a pair of stiffening bars (10. 11), one fitted at the front of the machine and the other at the back of it, the stiffening bars constituting an integral part of the machine frame and being able to slide inside corresponding seatings in a support (1) to be connected to the power take-off of the tractor.
