Patent IT-1214575-B (IT)
Title: Rotary distribution group for hydraulic motors
Inventor: IVANO DE VIETRO
IPC: F01L/
Filed: 1986-12-05
Granted: 1990-01-18
Abstract: The group comprises a revolving distributor disc coupled for rotation to the drive shaft and clamped between an axially movable reaction ring formed with separate passages connected to the ducts for supplying and discharging the hydraulic fluid, and a fixed distribution plate. This is formed with outlet orifices for the ducts supplying and discharging hydraulic fluid to the motor propulsors. The distribution disc is formed with at least two independent orifices communicating between its opposite flat surfaces and respectively in contact with the reaction ring and with the distribution plate, corresp. to the separate passages in the reaction ring and to the distribution plate, and thus driving the motor in rotation. Continuous surfaces are present for bounding and separating the respective inlet areas of the orifices in the disc towards the reaction ring and towards the distribution plate. The surfaces have cross-sections shaped so that they are immersed in the hydraulic fluid at least once per revolution. Ducts are also present for balancing the hydraulic pressure on the surface of the distributor disc, with respect to the diametral plane.

Title: Arc welding appts. using electronic controller and frequency converter - to obtain constant current even when short circuits occur
Inventor: BENGT JOHN
IPC: B23K/
Filed: 1977-05-10
Granted: 1985-05-28
Abstract: The appts. includes a controlled frequency converter with a hald period shorter than the average duration of the contact current and voltages caused by short circuits due to molten drops of welding material. The converter is connected via a transformer and rectifier to the electrodes; and a controller adjusts the converter so the welding current is constant despite the changes in load. The pref. controller continuously monitors arc current (A) and voltage (V), and includes a circuit measuring the voltage (P1) proportional to A x V. P1 is compared with a reference voltage (P2) representing the desired welding current, and the converter is adjusted to bring the difference P2-P1 to zero. The working frequency of the converter is pref. held constant; and capacitors and logic elements are included. Arc welding is simplified so that even semi-skilled workers can make good welds.

Title: Continuous casting metal plate - in machine using two cooled casting belts which are vibrated to reduce heat transfer
IPC: B22D/
Filed: 1978-02-13
Granted: 1985-12-09
Abstract: A casting belt is cooled and guided along a circular path in a plant for the continuous casting of metal plates, where two casting belts form the mould. A pressurised cooling liq. (I) is fed onto the reverse sides of the belts via a large number of separate honeycombs. (I) completely fills the honeycombs and the space between the latter and the belts, exerting a hydrostatic pressure on each belt so the latter are kept automatically at a constant distance from the honeycombs; and all buckling or warping of the belts is avoided. The belts surface in contact with the casting is pref. vibrated at 90 degrees to its surface to reduce heat transfer from the casting to the belt, esp. using vibration with frequency (f) 20-500/second and amplitude (h) esp. at the mould inlet of 2 x 10-5 to 2 x 10-4 m, partic, to obtain h.f2>0.5m/sec2. The vibration is pref. produced by magnetic fields, the belts being made of ferromagnetic material. A pref. casting machine uses two moving belts to form a vertical mould. The belts are kept in the exact position required, and the vibration reduces heat transfer from the casting to the belts.
