Abstract: A bladeless fan assembly includes a nozzle mounted on a base housing a device creating an air flow through the nozzle. The nozzle includes an interior passage receiving the air flow from the base and a mouth through which the air flow is emitted. The nozzle extends substantially orthogonally about an axis to define an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The depth of the base in the direction of the axis may be no more than twice the depth of the nozzle. The assembly produces an air current without requiring a bladed fan, that is, the air flow is created by a bladeless fan.

Abstract: The present invention relates to a device for laying an expansible lining in a conduit. The device may include a patch having an initial diameter less than that of the conduit, and the patch may be configured to deform by radial expansion beyond an elastic limit to an expanded diameter such that it may contact a wall of the conduit. The device may also include an expander tool axially displaceable inside the patch, and the expander tool may be configured to cause the radial expansion of the patch to an expanded diameter. The device may also include a checking member mounted in proximity to the expander tool. A section of the checking member may be calibrated so that the checking member and the expander tool are capable of passing freely inside the patch when the patch is properly expanded, and the checking member and the expander tool are unable to pass inside the patch when the patch is improperly expanded.
