A device for cutting successive sheets from a traveling web includes a pair of thin-walled knife-carrying cutting cylinders concentrically mounted over fixed supporting shafts. To prevent ringing of the shafts at high cutting frequencies, due to resonant frequency interference, each support shaft is formed by a body having an inperforate cylindrical wall. The cylindrical wall of the support shaft ...

Improvements to procedures for the splicing of yarns (20-21), whether textile or not, the splice being obtained by coupling two single untwisted yarns (20-21) and re-imparting the twists thereafter, in which improvements a part of the single yarns is untwisted until twists of a sign opposite to the original sign have been imparted, and such part is then coupled and small tails (220-221) are obtain...

A gearshift range preconditioning system includes a gearshift device which, when manually-operated to effect a gear-change, initiates a signal to an electronic logic circuit which is coupled to the vehicle to receive vehicle-operating characteristics such as speed and engine RPMs. The electronic logic circuit evaluates this change request and the received operating characteristics in relation to p...
