Abstract: A magnet vent assembly for venting a cryogenic gas from a superconducting magnet of an MRI system. The assembly comprises: a first burst disc, the first burst disc comprising a first inlet and a first outlet; a second burst disc, the second burst disc comprising a second inlet coupled to the first inlet and a second outlet coupled to the first outlet; and wherein the magnet vent assembly is configured to switchably direct a flow path of cryogenic gas through either of the following: the first burst disc and the second burst disc. A service tool for a magnet vent assembly for venting a cryogenic gas from a superconducting magnet of an MRI system. The magnet vent assembly comprises a first burst disc.

Abstract: A water jet aerator (jet controller) for a water outlet of a sanitary fitting has a substantially cup-shaped, plastic housing in which is located a device for mixing air with water made from a stable dimensionally rigid thermoplastic. The housing has a housing base molded in one piece therewith and which is constructed as a jet stabilizing device and is provided with water outlets between jet limiting walls parallel to the flow direction and which at the water outlet end have an elastic plastic surface. In the invention the jet limiting walls, at least in the vicinity of the water outlet, are solidly constructed from the elastic plastic over their entire wall thickness and are molded in one piece with the housing.

Abstract: An ethane recovery process resulting in a reduction in the amount of carbon dioxide in the recovered NGL stream is provided. To reduce the amount of carbon dioxide, a fractionation tower is provided with a bottom reboiler, and possibly one or more side reboilers higher up in the tower that are integrated with the cooling train. The process disclosed modifies the flow of cold liquid from the separator and tower reboiling to reject some of the more volatile components such as carbon dioxide from the less volatile fraction while maintaining recovery of desirable components such as C2+ hydrocarbon components. The modification includes heating a part of the separator liquid and introducing it at least one stage below the remaining liquid.

Abstract: A concentration cooling apparatus for a refrigerator includes a housing which is mounted in a cold air guiding path, and a nozzle which is rotatably supported in the housing, for concentratedly injecting cold air to a region where a high temperature load is generated when the high temperature load is generated in a predetermined region inside a cooling chamber. An infrared sensor is mounted at the front of the nozzle, for sensing the region where the high temperature load is generated. The sensor rotates together with the nozzle and a frost drying sensor is installed on the upper surface of the nozzle, for drying frost on the surface of the infrared sensor. Thus, the reliability of the infrared sensor can be improved by preventing the formation of frost on the surface of the lens of the infrared sensor which detects whether the high temperature load is generated.
