Abstract: An activation furnace for activating a fiber sleet having carbonized yarn filaments includes a horizontal activation enclosure containing a heater, an inlet section and an outlet section through which the fiber sheet travels. A supply of oxidizing gaseous fluid is provided within the enclosure, that further includes one heat treatment zone and, at opposite ends of the enclosure, a temperature-raising zone and a temperature-lowering zone. The inlet and outlet sections are fitted with airlocks connected to cooling and suction devices.

Abstract: This invention is directed to an apparatus for filling powder which comprises introducing a predetermined amount of powder into each of the receiving holes formed at the peripheral edge portion of a rotary disk from a powder hopper, intermittently rotating the rotary disk, and discharging and filling the powder accommodated in each of the receiving holes into a powder container positioned therebelow when each of the receiving holes reaches a discharging and filling portion. The rotational axis (C) of the rotary disk (1) is inclined. The center axis of each of the receiving holes (8) is arranged on an imaginary conical surface (12) having this rotational axis (C) as its center axis and an apex angle (.theta.) of 60.degree. to 120.degree.. The powder hopper (6) is disposed on the lateral side portion of an opening (8a) of the receiving hole (8) at a vacuum sucking portion (9) and a boss portion (28) supporting the rotational axis (34) of the agitator (7) is arranged above the powder hopper (6).

Abstract: A disk-brake pad device includes a carbon-carbon lining pad. The disk-brake pad device attaches the pad to the caliper. At least one pad-positioning surface of the caliper has merging therefrom at least one pad-actuating piston. A first plate element (1) of heat-insulating material, called a screen element, is located against the positioning surface. At least one second element (2) of heat-insulating material, called a spacer element, of adequate thickness, having reduced frontal contacts is located against the first element (1). A carbon-carbon lining pad (3) of high-temperature friction material is located against the second element (2). The first element (1) and/or the second element (2) acts to retain the lining pad (3) and to fix the first element and/or the second element to the caliper.

Abstract: The present invention concerns a clutch with structural friction plates, especially of carbon-carbon, comprising a drive flywheel, a first driving plate forming a first non-clutching interface with the flywheel, at least one pair of driven plates connected to an output shaft, and a driving plate being interposed between each pair of driven plates. A second driving plate and a thrust plate form a second non-clutching interface with the second driving plate. A casing has a mechanism operable to apply pressure to the thrust plate and is provided with bars fitted into radial recesses of the driving plates and being fixed to the flywheel. A packing-up device eliminates the play at at least one of the non-clutching interfaces and the device presses the driving plate against the adjacent part.

Abstract: The present invention relates to a disc brake for an automobile including a disc comprising an outer part made of carbon/carbon mounted to slide axially on an inner part fixed to a stub axle. Pads, configured as rings coaxial to the disc, define braking surfaces which totally cover the axial faces of the outer part. The pads, also preferably formed of carbon/carbon, are mounted in a pad support in the form of a cage thermally protected from the pads by radiators. Jacks are interposed between an annular shield of the pad support and one of the pads to shift the pad relative to the disc.

Abstract: The present invention concern a clutch with structural friction plates, especially of carbon-carbon, comprised of a drive flywheel, a first driving plate forming a first non-clutching interface with the flywheel, at least one driven plate connected to an output shaft, a driving plate interposed between each pair of driven plates, a second driving plate, a thrust plate forming a second non-clutching interface with the second driving plate, and a casing. A mechanism is operable to apply pressure to the thrust plate and is provided with bars fitted into radial recesses of the driving plates and is fixed to the flywheel. The mechanism includes a "progressive" device interposed in at least one of the non-clutching interfaces which urges the driving plate of the interface towards the adjacent driven plate and against an abutment.

Abstract: An improved rotor for a disk brake is disclosed having a multi-piece construction. The rotor has a central web extending around a driving drum portion such that the web defines several generally radially extending cooling passages. The central web is mounted on the driving drum portion so as to be capable of sliding laterally, but may not rotate relative to the driving drum. Friction elements, completely separate from the central web, are located on either side of the central web and are mounted on the driving drum so as to be also capable of lateral movement. The friction elements are also prevented from rotating relative to the driving drum portion of the rotor.

Abstract: A disk brake assembly including a single annular stator disk slidably mounted on fingers provided on the hub carrier of a wheel and movable into engagement against a single annular rotor disk by a plurality of hydraulically-actuated cylinders disposed within the hub carrier, the rotor disk being slidably mounted on a counter-thrust plate that is detachably secured to the front face of a hub flange and rotated by the hub.
