Abstract: The invention relates to a cryogenic unit comprising: a cryogenic tank; a receptacle; a pipe comprising: a first end connected to the cryogenic tank; a second end; a first longitudinal portion; a second longitudinal portion; a bend between the first portion and the second portion; a connecting flange situated between the bend and the second end, wherein the cryogenic unit further includes: an item of fluidic equipment comprising an inlet end; and an outlet end and configured to be mounted removably inside the receptacle.

Abstract: Some embodiments are directed to a kit of parts that includes heat sink parts, each heat sink part having a contact area for contacting a surface of an electronic device. The heat sink parts are connected but are spaced apart to allow them to adjust and keep their contact areas contacting the surface of the electronic device when the surface is distorted, for example due to heating. A heat sink part includes at least two spaced apart heat sink elements which are connected.

Abstract: An isothermal container for preserving and/or transporting perishable or heat-sensitive products, includes a cryogenic compartment for a mass of a cryogenic fluid, a product storage compartment for the products to be preserved or transported, at least one Seebeck module, and at least one fan positioned within the product compartment to create forced convention therein that is electrically powered by the Seebeck module, which generates a voltage from the difference in temperature between the mass of cryogen and the ambient air temperature of the product compartment.

Abstract: The invention relates to a method and equipment for filling at least one downstream tank with a cryogenic liquid, from an upstream store which contains, at a storage pressure above atmospheric pressure, the cryogenic fluid in the liquid phase at the bottom of the tank, and the cryogenic fluid in the gas phase at the top of the tank, said upstream store being suitable for feeding liquid withdrawn from the bottom of the store to the downstream tank, as well as to be supplied with fluid from the outside, characterized in that one generates and maintains a pressure difference between the upstream store and the downstream tank, by pressurizing the gas phase of the upstream store at a pressure that is greater than the equilibrium pressure of the store.

Abstract: The device is meant to move the solar protection means from a first position, among at least two predetermined positions, toward a second position to adapt to a variation in sunshine. It comprises a logic (6) which breaks down movement from the first to the second position into a minimum of two steps separated by a time interval (T1). A command (STOP) activated by a user during said interval (T1) activates the following step and reduces the interval by a fraction. The activation of an order after the interval (T1) and during the operation of the following step increases the interval (T1) by a fraction. The control device is in this way capable of adapting to the behavior of the user.

Abstract: An automatic sample testing machine for testing samples stored in test cards. The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles.

Abstract: A positioning system for a sample testing machine incudes a base pan and a set of independent drive systems for sliding a sample tray across the base pan. Each of the drive systems incudes a paddle that engages a side of the sample tray. The paddle is slideably mounted to a shaft with a collar that slides over the shaft. A motor and drive belt is provided to move the collar along the shaft, causing the paddle to engage the side of the sample tray and slide the sample tray across the base pan. Track sections are provided in the base pan to prevent the sample tray from rotating as the paddle slides the sample tray across the base pan.
