Abstract: A method for supplying a user station for carrying out machining operations with a cryogenic fluid, having a liquid/gas two-phase fluid from a cryogenic fluid storage tank, the cryogenic fluid storage tank contains, under a storage pressure higher than atmospheric pressure, a cryogenic fluid in the liquid phase at the bottom of the tank and in a gaseous phase at the top of the tank, the tank being designed to supply the station with liquid phase withdrawn from the bottom of the cryogenic fluid storage tank. Wherein a gas/liquid phase separation means is provided, which is supplied with the liquid/gas two-phase fluid from the tank and carries out a separation of a substantially liquid phase and a substantially gaseous phase of the cryogenic fluid, the substantially liquid phase being directed toward the user station; wherein the gas/liquid phase separation means has a gas outlet.

Abstract: A method for machining workpieces, having a cryogenic fluid intake in a machining zone, including locating a valve on the line connecting a fluid source to a machining tool in the machining zone, the valve self-regulates the degree of opening according to the pressure required downstream thereof, the valve is located inside a cold box for implementing the cryogenic fluid and provides a fixed and adjustable pressure, and a fixed adjustable flow, to the machining tool, irrespective of the tool that is used, and the number of orifices and the diameter of the fluid ejection orifices in the tool.

Abstract: A plant for grinding a product, which includes a grinder in which the product is ground, which plant also includes a hopper for supplying the grinder with product to be ground, configured to be supplied with product to be ground; a means for bringing a cryogenic fluid into the hopper; and a means for discharging product from the hopper into the grinder. Wherein the hopper is provided in a lower part with a hollow screw provided with turns allowing the product to be discharged out of the hopper, into the grinder; and the means for bringing a cryogenic fluid into the hopper comprise an injection lance which is positioned inside the turns of the hollow screw, extending in a direction substantially parallel to the axis of the screw.

Abstract: The invention relates to a method for anaesthetizing animals before slaughter, by the anesthetic action of gases or gas mixtures, operated in “batch” mode, in which the live animals, preferably put together in one or more cages, are placed in a lock chamber for treatment where the animals are brought into contact with anesthetic gas, following a cycle comprising several steps characterized by different contents of anesthetic gas, characterized in that at least one of the steps is carried out using gas recovered from the lock chamber and stored in at least one capacity (2, No. 1, No. 2 etc.) for temporary storage having a variable volume.

Abstract: A method and an installation seeking to create a controlled atmosphere in the head space of a product storage container in an installation of the type in which the following measures are taken continuously: —the container is partially filled with the product to a given fill level; —the upper part of the container is placed in contact with a treatment gaseous atmosphere aimed at removing all or some of the air present in the container above said fill level and at installing the required controlled atmosphere above said level; —the upper edge of the container is sealed or closed using a suitable means; —the controlled atmosphere being installed upstream of and/or during sealing, characterized in that the controlled atmosphere is installed in an uncontained injection zone by using at least one injector of tubular type oriented in the injection zone in such a way that at least one of the components of the velocity of the sprayed gas is the opposite to the direction of travel of the containers, and in that the inj
