Latest Patents

One of his latest patents is a mandrel designed to be inserted into a liquid circulation pipe, which includes a radially expandable annular sealing element. This mandrel features a body and a centering arrangement, along with a closure arrangement that can be deployed radially between contracted and dilated configurations. Additionally, it comprises an anchoring element positioned at a longitudinal distance from the sealing element, which is also radially expandable. The mandrel includes sequencing means capable of deploying the closure arrangement after the anchoring and centering arrangements. In its at least partly deployed configuration, the centering arrangement defines at least one axial passage through the annular sealing element, while the closure arrangement effectively closes these passages as it is deployed.

Another significant patent by Millet is a safety device for an oil well, which includes a valve housing defining a fluid flow passage.
