  • Patent number: 5062515
    Abstract: The control device of a disc clutch consists of a cylinder (2) and of a piston (1). An orifice (3) makes it possible to feed under pressure into a chamber (17) formed between the cylinder and the piston fluid which comes from the master cylinder actuated by the clutch pedal. Under the pressure of the fluid, the piston (1) moves away from the cylinder (2) and controls the opening of the clutch. The device is arranged directly on the tube (8) surrounding the driveshaft, without any other fastening means. O-ring gaskets (11) make it possible to hold the device on the tube and ensure the damping of possible vibrations.The clutch bearing is incorporated in the free end of the piston (1) in the form of a thrust ring (20) held by a ball-bearing fitting.

  • Patent number: 5060347
    Abstract: Non-woven fabrics are manufactured using a carding machine with outlet comb, a blamire feed or spreader/batt-making machine with cylinders for depositing a web of fibers, and one or more needling devices. The surface weight of the web delivered by the carding machine to the blamire feed is modified by varying the speed of the comb as a function of the changing positions of the cylinders whereby a batt of variable surface weight over its width is obtained so as to counteract the distortions of surface weight distribution produced by the needling devices.
