| 20080307800 | Siphon for Delivery of Liquid Cryogen from Dewar Flask - The invention involves a siphon for delivery of a liquid cryogen from a container such as a Dewar flask. The siphon ensures delivery of a liquid cryogen with a lower proportion of the gaseous fraction. The siphon comprises a central feeding conduit, which is largely contained within the Dewar flask. There is an auxiliary conduit surrounding the central feeding conduit; the outer upper section of this auxiliary conduit is provided with an adjustable valve intended to release a gaseous fraction of the cryogen contained in the annular gap between the auxiliary and central feeding conduits. The upper section of the central feeding conduit is provided with an external layer of a porous capillary coating or with a wick; this ensures that the upper section of the central feeding conduit is continuously wetted with the liquid cryogen. This porous capillary coating prevents gasification of the liquid cryogen in the central feeding conduit. Alternatively, the problem of liquid cryogen gasification may be solved through thermal insulation of the central feeding conduit. | 12-18-2008 |

| 20090272127 | Cryogenic vacuum break thermal coupler with cross-axial actuation - A system and method to connect a cryocooler (refrigerator) to a superconducting magnet or cooled object allows for replacement without the need to break the cryostat vacuum or the need to warm up the superconducting magnet or other cooled object. A pneumatic or other type of actuator establishes a thermo-mechanical coupling. The mechanical closing forces are directed perpendicular (cross-axially) to the cryocooler axis and are not applied to the thin wall cryocooler body or to the thin cryostat walls or to the cooled object or to its shield. It is also possible that some of the compressive force be transferred to the cryocooler body. In that case, the extensions are designed so that the forces transferred to the cryocooler thermal stages do not exceed allowable stresses in the cryocooler stage. Additionally the device provides the possibility of easy inspection and cleaning of the thermal contacting surfaces of the cryostat cold and intermediate stations from the bonded chips of compressible gasket after the cryocooler retraction. | 11-05-2009 |

| 20150027136 | Storage and Dispensing System for a Liquid Cryogen - A two line system for storing and dispensing cryogenic liquids from a bulk storage tank to a secondary container without the use of a cryogenic pump. A first line is in communication with the vapor space of a secondary container and a compressor, the compressor being used to depressurize the secondary container to a point where the bulk storage tank is at a higher pressure than the secondary container. The first line can direct the evacuated gas either into the bulk storage tank, towards separate holding tanks, or towards any other application. A second line is in communication between the bulk storage container and the secondary container. When the compressor is activated, the pressure in the secondary container will fall below the pressure in the bulk storage tank, causing the cryogen to flow from the now higher pressure bulk storage tank into the secondary container. | 01-29-2015 |
