  • Device and method for extrusion of a solid body
    Patent number: 9873214
    Abstract: The extrusion device of a solid film comprises a cell provided with an input opening of a material designed to form the solid film, and an output opening of the solid film from the cell. The device comprises a first heat exchanger for applying a first temperature to the output opening and a second heat exchanger for applying a second temperature in a first zone of the cell distinct from the output opening and a control circuit imposing first and second sets of first and second temperatures. The first set enables a volume of the material in solid phase to be formed. The second set enables a temperature gradient to be generated in the volume so as to generate a pressure forcing extrusion of the solid film via the output opening.

  • Cryorefrigeration Device and Method of Implementation
    Publication number: 20130133341
    Abstract: The invention proposes a reliable high-performance cryorefrigeration device, the level of thermal oscillations of which may be minimized so as to be below a threshold value. For this purpose, the subject of the invention is a cryorefrigeration device comprising N periodically operating cryorefrigerators (100), N being an integer equal to or greater than 2, each cryorefrigerator being provided with a cold end coupled to a common cold end (300), the cryorefrigerators being linked to a control device provided with a phase-shift means capable of making the cryorefrigerators operate in phase-shifted relationship one with respect to another.
