  • Publication number: 20170326716
    Abstract: A handheld guide for advancing and installing a decking fastener with an elongate track with a rail and an advancement member. The advancement member carries a pivoting pawl with an engagement surface for advancing fasteners forward through the track to an installation position with a frontmost fastener aligned with a screw guide for driving a screw through the frontmost fastener. The rail has a ramp transitioning to a cliff and a lower ledge such that the frontmost fastener is maintained forward of the cliff above the ledge in the installation position. The pawl pivots to disengage from the fasteners when the advancement member moves rearwardly along the track.

  • Patent number: 9638049
    Abstract: A turbine engine blade includes an airfoil connected by a platform to a middle radial wall extending axially and prolonged radially inwards by a blade root that is mountable in a slot of a disk, and the platform and the middle radial wall defining two lateral cavities situated on either side of the middle radial wall and opening out circumferentially to receive scaling members. The cavities are open downstream with two fins projecting on either side of the middle radial wall at downstream end of the middle radial wall, the fins coming to bear against two adjacent teeth of the disk between which the slot is formed. The downstream end of the middle radial wall includes a setback extending between at least one rib of the platform and the fins.

  • Patent number: 9567861
    Abstract: A turbomachine vane for cooperating with a vane retention disk including a plurality of peripheral teeth, the vane including a shank including a neck and a bulb for cooperating with a socket of the disk so as to radially hold the shank in the socket, the socket being a space bounded by two successive teeth of the disk, a pole on top of the neck, including two side walls facing the active surface side of the vane and two side walls facing the passive surface side of the vane, each wall having a rib at a lower end of the pole, the rib extending in the direction of the side wall facing the wall and providing a function of holding the vane when the vane is retained in the disk.

  • Publication number: 20160129497
    Abstract: The invention relates to a blade preform (46) including a strut connecting a plat-form (16) to a blade root portion (14) extending longitudinally in an upstream-downstream direction, an upstream web (26) and a downstream (28) web, which each extend in a direction substantially perpendicular to the longitudinal direction of the blade root and are formed at the upstream and downstream ends of the strut. The upstream (26) and downstream (28) webs connect the upstream and downstream ends of the plat-form (16) to the upstream and downstream ends of the blade root (14). According to the invention, the blade root (14) extends in a direction perpendicular to the longitudinal direction of the blade root over a distance smaller than that of the upstream and downstream webs (26, 28) and the side edges (40) of each web (26, 28) are extended by walls that converge (44) at the flanks of the blade root.

  • Patent number: 9333922
    Abstract: A kayak holder configurable between an open, load-receiving configuration and a closed, stored configuration can include an elongate support arm and a base. The base can be releasably mountable upon a load bar of a carrying vehicle. The elongate support arm can be anchored to a hub having an axle rotatably coupled to the base. The base can comprise a keyway assembly that releasably receives a mating key assembly on the axle. A biasing member interposed longitudinally between the axle and the base configured to bias the at least one support arm toward a locked position. The at least one support arm is unidirectionally axially displaced relative to the base between the locked position and an unlocked position.

    Abstract: A kayak holder configurable between an open, load-receiving configuration and a closed, stored configuration can include an elongate support arm and a base. The base can be releasably mountable upon a load bar of a carrying vehicle. The elongate support arm can be anchored to a hub having an axle rotatably coupled to the base. The base can comprise a keyway assembly that releasably receives a mating key assembly on the axle. The elongate support arm can have a locked position where the key assembly is interference-engaged in the keyway assembly and an unlocked position where the key assembly axially displaced from the locked position out of interference-engagement with the keyway assembly. The key assembly can include a key adapted to be located in a keyway of the keyway assembly in the locked position, thereby blocking rotation of the arm relative to the base.

  • Publication number: 20150027089
    Abstract: A vacuum sealing appliance is provided including a vacuum motor assembly generating suction, a vacuum trough fluidly connected to the vacuum motor assembly configured to receive suction and evacuate a food container through an open end, and at least one heat sealing element adjacent the vacuum trough configured to heat seal the open end of the food container after evacuation. The vacuum sealing appliance further includes a control unit configured to control the vacuum motor assembly and the at least one heat sealing element. The vacuum sealing appliance further includes at least one channel disposed proximate the heat sealing element. The channel is fluidly connected to a cooling fan that generates a cooling air flow through the channel to remove excessive heat from the heat sealing element to prevent premature sealing of subsequent food containers between heat sealing events.
