Abstract: A device for collecting sap from a tapped hole in a tree and directing the sap to a sap collecting tube that is removably connectable to the device. The device comprises a tapping member with a first portion that is removably insertable into the tree and a second portion extending outside the tree when the first portion is inserted into the tree and a connecting member with a connecting portion adapted to be mounted to the second portion of the tapping member and a fitting portion adapted to receive the sap collecting tube. The device also comprises a securing means for locking the connecting member relative to the tapping member such that longitudinal movement of the connecting member is prevented and a seal mounted between the second portion of the tapping member and the connecting portion of the connecting member.

Abstract: A system for controlling a leakage zone under platforms of blades of a turbomachine blade-wheel by liners having edges that flare radially inwards, and that are disposed in inter-blade cavities defined by the platforms, by upstream and downstream radial walls of the blades and by the periphery of the wheel disk. One of the flared edges, upstream or downstream, presents an elastic zone bearing on an inclined surface of the adjacent radial wall relative to a radial plane, such that the liner tends to move axially towards the radial wall facing, under action of centrifugal forces, to improve sealing in the zone, and so that when the wheel stops, the elastic zone moves radially inwards, the liner pivoting around an axis distant from the elastic zone.
