  • Publication number: 20170341262
    Abstract: A wood-thawing installation for thawing frozen pieces of raw timber includes a thawing channel. The thawing channel has an entrance and an exit for the pieces of raw timber for the raw wood pieces to enter and exit the thawing channel. A plurality of nozzles are located on the thawing channel to introduce a thawing liquid into the thawing channel. A first section of the thawing channel and a second section of the thawing channel are located between the entrance and the exit. The exit is closer to the second section than to the first section. At least one of the nozzles is located in the first section and connected via a pumping line to a suction opening located in the second section. Further disclosed is a method for thawing frozen raw wood pieces.

  • Publication number: 20120328081
    Abstract: An X-ray tube comprises a containment element (2) in which a cathode (4) and an anode (5) are mounted. The anode (5) comprises a first main face (6) which is substantially facing towards the cathode (4) and a second main face (7) which is facing the opposite way to the first face (6). There are also cooling means (8) applied to the second main face (7) of the anode (5) and filter means (10) for filtering, based on respective wavelengths, the X-rays emitted by the anode (5). The cooling means (8) and the filter means (10) both consist of a heat conductor element (9) which is thermally coupled with the second face (7) of the anode (5) and which is equipped with a plurality of inner micro-channels in which, in practice, a pressurised coolant liquid can flow with a turbulent motion.

  • Patent number: 5306993
    Abstract: Machines having torques variable as a function of the angle of rotation such as piston driving mechanisms like compressors, cam driving mechanisms, printing machines and looms, are driven by an electric motor in such a way that a trend in angular velocity which is dependent upon the angle of rotation, in particular also a constant angular velocity of the main driving shaft (2) of the driven machine, may be predetermined. To do this the angle of rotation (3) as well as the torque (4) are picked up off the main shaft (2) and fed to an adaptive control system (S) which, starting from the desired values (s0) of the angular velocity as a function of the angle of rotation, applies a corresponding correcting variable (Y) to the electric motor (1) and iteratively adapts it periodically in order to bring the trend in angular velocity of the main shaft (2) into agreement with the desired value (s0).
