Patent number: 8294463Abstract: A valve for controlling cryogen egress from a cryogen vessel has a housing having a low pressure side and a high pressure side with a fluid path defined between. A valve element is interposed between the low pressure side and the high pressure side of the housing. A mechanism is provided for holding the valve element against a valve seat. The mechanism has a cam shaft that is rotatable to displace the valve element from its seat to open the fluid path.Type: GrantFiled: September 1, 2009Date of Patent: October 23, 2012Assignee: Siemens PLCInventors: Trevor Bryan Husband, Philip Alan Charles Walton

Patent number: 7987867Abstract: A burst disc arrangement for a cryostat comprising a replaceable burst disc (52) held in compression between a high-pressure flange formed at an end of a high-pressure conduit (12), and a low-pressure flange (60) formed at an end of a low-pressure conduit (14). In particular, the burst disc arrangement further comprises: a housing (50) enclosing the high- and low-pressure flanges; and compression means (56), distributed around the housing (50) and being arranged to bear upon the one of the flanges (60), so as to urge it towards the other flange, thereby retaining the burst disc (52) in compression between the flanges. The housing (50) includes a first opening (20) large enough to allow the replaceable burst disc (52) to pass therethrough.Type: GrantFiled: March 14, 2008Date of Patent: August 2, 2011Assignee: Siemens PlcInventors: Trevor Bryan Husband, Philip Alan Charles Walton

Publication number: 20090205721Abstract: A burst disc replacement apparatus (100) comprises a magazine (122) that carries a first burst disc (232) and a second burst disc (234). A flow path (104) passes through the apparatus (100) for venting fluid. The first burst disc (232) is located in the flow path (104). A translation mechanism (112, 144, 146, 200, 214, 220, 222) is arranged to move the second burst disc (234) into the flow path (104) in place of the first burst disc (232) in response to an indication that fluid pressure at one side of the first burst disc (232) has exceeded a predetermined pressure corresponding to rupture of the first burst disc (232).Type: ApplicationFiled: February 13, 2009Publication date: August 20, 2009Applicant: Siemens Magnet Technology Ltd.Inventors: Trevor Bryan HUSBAND, Philip Alan Charles Walton

Publication number: 20090205720Abstract: A burst disc replacement apparatus (102) comprises a magazine (114) carrying a first burst disc (116) and a second burst disc (118). The apparatus also comprises a flow path (104) therethrough for venting fluid. The first burst disc (116) is located in the flow path (104) and the second burst disc (118) is located outside the flow path (104). A translation mechanism is also provided and coupled to the magazine (114) and arranged to permit manual translation of the magazine (114) so that the second burst disc (118) moves, when in use, into the flow path (104) in place of the first burst disc (116).Type: ApplicationFiled: January 14, 2009Publication date: August 20, 2009Applicant: Siemens Magnet Technology Ltd.Inventors: Matthew HOBBS, Trevor Bryan Husband, Philip Alan Charles Walton

Publication number: 20090158752Abstract: A compressor (1) including a compressor mechanism; an input line (12) for providing gas to the compressor; and an output line (14) for providing compressed gas from the compressor. The compressor may supply gas at a first pressure or at a second pressure, by variation of the charge pressure within a gas circuit. A buffer volume and arrangement of valves, contained within the compressor, facilitate the change in static charge pressure. The electrical power drawn by the compressor is reduced when the charge pressure is reduced. Changing the charge pressure in the compressor also varies the cooling power delivered by the refrigerator. Therefore, this variable charge compressor can be used to reduce the electrical power drawn by an MRI system when it is in standby, and the full refrigeration capability is not required. Also, this has the effect of reducing wear and increasing the life of certain components within the refrigerator and compressor.Type: ApplicationFiled: December 17, 2008Publication date: June 25, 2009Applicant: Siemens Magnet Technology Ltd.Inventors: Nicholas John CLAYTON, David Gubbins, Trevor Bryan Husband, Philip Alan Charles Walton

Publication number: 20090082657Abstract: A magnetic resonance imaging system has a superconducting magnet contained within a cryostat, the cryostat being cooled by a cooling system that includes a healing and compressor, a refrigeration device and a local supervisory system. The helium compressor provides compressed helium to the refrigeration device, and the local supervisory system controls operation of the refrigeration device. The helium compressor is in communication with the local supervisory system, and also is able to communicate, independently of the local supervisory system, with a remote service provider.Type: ApplicationFiled: September 26, 2008Publication date: March 26, 2009Inventors: Michael John Dalchau, Russell Peter Gore, Rolf Heinrichs, Trevor Bryan Husband, Philip Alan Charles Walton
