Abstract: A magnet assembly has a number of axially-aligned coils, the radial mid-point of each coil being axially-aligned with a portion of a radial extent of an adjacent coil in the assembly. Compression blocks are provided between adjacent coils at circumferential intervals, to retain the coils in fixed relative positions.

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: A hollow cylindrical vessel comprising a cylindrical outer shell (12) and a cylindrical inner shell (14) joined by annular end caps (16), wherein at least one of: an end cap, or the cylindrical outer shell (12), or the cylindrical inner shell (14), is provided with an arrangement of recesses or protrusions (18). Preferably, the arrangement of recesses or protrusions is asymmetrical in all axes.

Abstract: An improved money transfer system. A rules database includes transaction rules that include an aggregation threshold. A customer database includes customers' transaction histories. A processing system receives transaction requests from points of entry and provides transaction responses. Based on information received in transaction requests, the processing system identifies customers and determines applicable transaction rules. An aggregation engine determines aggregation values as a function of customers' transaction histories. A transaction rules service determines whether information received in the transaction requests meets the applicable transaction rules and causes the aggregation engine to determine aggregation values if the applicable transaction rules include aggregation thresholds. Transaction responses are generated by the processing system in response to any aggregation values and other information.

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: An assembly includes a cylindrical magnet assembly, which includes comprises at least one coil mounted on a former. The assembly also includes a bore tube with a number of radially-directed retaining protrusions formed in a material of the bore tube, each of the number of radially-directed retaining protrusions configured to bear against a periphery of a corresponding cavity in the former.

Abstract: A data processing system coupled to a rules database and a customer database is responsive to transaction requests representative of money transfers. The rules database includes information representative of transaction rules such as location-based rules, transaction type-based rules, customer-based rules, aggregated transaction value rules and currency exchange rules, at least some of which include an aggregation threshold. The system processes the transaction requests during transaction processing sessions to enable enforcement of governmental money transfer compliance requirements. Responses including requests for additional information, approvals and denials are provided by the system.

Abstract: A tool for assembling a cylindrical magnet assembly to a bore tube and a resulting assembly. The cylindrical magnet assembly includes at least one coil mounted on a former. A cavity is provided in the former at selected locations. At each of the selected locations, the material of the bore tube is deformed to form a radially-directed protrusion. Each protrusion is brought to bear against a periphery of each corresponding cavity.

Abstract: A method for progressively introducing current into, or removing current from, a superconducting coil mounted on a former, in which the coil vibrates relative to the former.

Abstract: An improved money transfer system includes a rules database, a customer database, and a transaction processing system. The rules database includes information representative of transaction rules, at least some of which include an aggregation threshold. The customer database includes information representative of customers' transaction histories. The transaction processing system is connected to the rules database and customer database and includes point of entry ports, a customer identifier, a rules coordinator, an aggregation engine, and a transaction rules service. The point of entry ports receive transaction requests from points of entry and provide transaction responses to the points of entry. Based on information received in transaction requests, the customer identifier identifies customers and the rules coordinator determines applicable transaction rules. The aggregation engine determines aggregation values as a function of customers' transaction histories.
