Abstract: A device for cutting a web of fibrous material including movement means for moving a web of fibrous material to be cut, defining a feed surface for the web and having at least one first cutting zone, at least one laser source configured to generate a laser beam extending along its operating direction towards the first cutting zone to make, on the web, at least one incision extending along a predetermined cutting line, where a portion of the laser beam passes through the web of fibrous material at the first cutting zone. The device also includes recovery means for recovering the portion of the laser beam and at least partly located along the operating direction, at the first cutting zone, in such a way as to intercept the portion of the laser beam and direct it towards a second cutting zone to make a further incision or cut.

Abstract: A device is provided for automatically indicating an insufficient level of oil in a motor-vehicle gearbox of the automatic type. The device includes an oil level sensing system controlling an associated indicator. To prevent spurious operation of the indicator, the device is provided with a number of sensors arranged to ensure that the oil-level sensing system can only effect control of the indicator under certain predetermined conditions including that the vehicle is stationary and on the level, and that the engine is idling. An oil temperature sensor is also provided either to prevent operation of the indictor if the oil temperature is outside a predetermined range, or to effect a temperature dependent adjustment of the acceptable value of oil level.
