Abstract: In a superconducting magnet apparatus, at least one superconducting winding and an outer vacuum chamber are provided. A thermal radiation shield is located between the superconducting winding and the outer vacuum chamber. A cryogen vessel is positioned within the thermal radiation shield and within the outer vacuum chamber. The superconducting winding is positioned outside of the cryogen vessel. A refrigerator is operable to cool the cryogen vessel to a liquid cryogen temperature and to cool the at least one thermal radiation shield to an intermediate temperature between the liquid cryogen temperature and a temperature of the outer vacuum chamber. A substantial portion of an outer surface of the cryogen vessel has a thermal emissivity at the liquid cryogen temperature which is greater than an average surface emissivity of the superconducting winding by at least 0.1.

Abstract: A cylindrical magnet assembly has at least one coil mounted on a former, assembled to a bore tube by a number of inserts within holes formed in a material of the former. Each insert can bear on a dished radially outer extremity of a radially-outwardly directed protrusion or each insert can bear on a radially outer concave surface of a radially-inwardly directed protrusion.

Abstract: Systems and methods of allocating tasks to servicers are disclosed. The systems and methods select one of the servicers and one of the tasks based on selection criteria. The systems and methods then determine whether the selected task may be allocated to the selected servicer. If the selected task may be allocated to the selected servicer, the systems and methods allocate the task accordingly. If the selected task may not be allocated to the selected servicer, the systems and methods select another one of the servicers and another one of the tasks.

Abstract: A system for providing an automated axial force to a continuously variable transmission (CVT) in a wheelchair. An electronic transmission control receives one or more input signals generated by throttle position or other variables. The microprocessor generates an output signal that adjusts the axial force applied to a CVT thereby automatically adjusting the input to output ratio. The invention also provides a manually controlled variator is designed for use on a wheelchair. The manual shifter hydraulically adjusts an axial force imparted on a variator in communication with a wheelchair wheel and a hand rim. Application of the axial force causes the hand rim input and wheelchair wheel output ratio to change, permitting a wheelchair operator to manually adjust the input to output ratio to more easily operate the wheelchair.
