  • Patent number: 8011357
    Abstract: A cutting and dust collecting assembly comprises a rotatable, circular saw blade (4) having a first side (20), a second side (21), and a cover device (6) with a terminal member (52). The bottom surface (36) of the cover device extends in a plane. A longitudinal passage (45, 46) for the saw blade extends through the cover device from its top surface to its bottom surface. The terminal member comprises a terminal chamber (60) having an inlet (45a), the mouth of which coincides with the plane of said bottom surface. An outlet (58) can be connected to a vacuum source. The direction of rotation of the operating blade is such that the rear part (4a) of the saw blade which has passed beyond the bottom surface of the cover device will move in a direction upwards-rearwards towards the bottom surface. The invention also concerns the cover device, a sealing body belonging to the cover device and a working machine which is provided with the cutting and dust collecting assembly.

  • Publication number: 20080284148
    Abstract: An inflator for an air-bag comprises at least one gas bottle (1, 2) containing pressurised gas. The gas bottle is sealed by a rupturable foil (9). There is a support member (15) engaging the rupturable foil to maintain it in an unruptured state. The support member (15) is retained in an initial position by a part (23) of a piston element (20) which directly engages the support member (15). The piston element (20) is associated with a squib (11) to drive the piston element from an initial position to a release position in which the piston element no longer engages the support member (15). This permits the support member (15) to move to a position in which the foil (9) will rupture to permit gas to escape from the bottle. The preferred embodiment has two gas bottles each sealed by a respective foil each maintained by a support member which directly engages a single piston member.
