Title: Current leads for cryogenically cooled equipment
Inventor: STAUTNER WOLFGANG
IPC: F25B9/14
Filed: 2006-02-17
Abstract: A cryostat is cooled by a pulse tube refrigerator 30 and contains electrically powered equipment 10, where an electrical conductor is provided to the electrically powered equipment, the electrical conductor being coaxially arranged with respect to an individual pulse or regenerator tube of the pulse tube refrigerator, and isolated therefrom by a vacuum region. Preferably, individual vacuum tubes 60 are provided around each of the pulse and regenerator tubes of the pulse tube refrigerator. These vacuum tubes may be cooled by the pulse tube refrigerator either by thermal conduction along their length to the cold stages 34, 38 or by thermal radiation to the material of the corresponding pulse or regenerator tubes. Preferably, the vacuum tubes are used as current carrying conductors to take electrical current to and from a magnet 10 during ramping up and ramping down. In a second aspect, an electrical conductor 64 is in thermal and mechanical contact with one or more of the tubes of the pulse tube refrigerator. The electrical conductor may be provided with an electrically insulating, thermally conductive layer interposed between the conductor and the corresponding tube(s). Preferably, when electrical current conduction is not required, the conductor is arranged to be brought out of connection with the tube(s). The conductor may comprise two half-cylindrical metal sheets, such as brass, which are electrically insulated from the material of the tube(s), either by a self-adhesive polyimide film lining or by an epoxy resin filled with glass and/or aluminium oxide lining. Preferably, a flow of cryogen gas, such as helium, is provided to cool the outer surface of the conductor. The electrical conductor may alternatively comprise a hollow expanding electrically conductive member with conformal surfaces.

Title: A Layered Electrically Heated Fluid Line
Inventor: MULLER DOMINIC
IPC: F16L53/38
Filed: 2007-10-16
Abstract: An electrical heatable fluid line 1 includes an inner cross sectional area 3 which surrounds a medium conducting duct 2, a heating conductor 5 arranged in a thermally conductive connection with the inner cross sectional area 3, and an outer cross sectional area 6. An intermediate layer 7 surrounds the heating conductor arrangement 5 and the inner cross sectional area 3 such that the intermediate layer 7 separates the heating conductor arrangement 5 from the outer cross sectional area 6. The intermediate layer 7 has a mechanically lower stability than the inner cross sectional area 3 and the outer cross sectional area 6. Such an arrangement allows the intermediate layer 7 to be removed easily to expose the heating conductor arrangement 5 for electrical connection. The intermediate layer 7 may be made of a material that can be removed by rubbing.

Title: An ESD protection circuit for a transmitter output
Inventor: PUGSLEY WILLIAM
IPC: H03F1/52
Filed: 2008-10-17
Abstract: An ESD clamp is effective to protect a node 201 irrespective of whether or not the circuit is powered up. The gate of the PMOS trigger transistor 203 is coupled to Vdd 206 so that it turns on to trigger the clamp transistor 202 when an overvoltage occurs at node 201. A series diode (301, figure 3) may be inserted to reduce capacitance on the node 201 and to raise the effective threshold voltage of the trigger device 203. A gate-source resistor (302, figure 3) may be provided to remove charge accumulated by rectification of transients on node 201. Leakage current through the clamp 202 is reduced by a gate-earthing device 401, which is disabled by trigger device 403 and inverter 402 when an ESD overvoltage occurs on node 201. Alternatively, the gate of transistor 202 may be earthed through a resistor (205, figure 2). The ESD protection circuit presents a low capacitance to the protected node and is suitable for protecting the output of an RF transmitter IC.
