摘要:
The present provides a cryogenic thermal battery arrangement for maintaining a superconducting magnet coil or similar apparatus at cryogenic temperature for a required shipping period, such as thirty days, without consuming a significant amount of costly cryogen. According to another aspect, the invention allows extended shipping periods without incurring excessive costs.
摘要:
A cryogen tank in thermal and mechanical attachment with the equipment to be cooled. Direct thermal conduction between the cryogen and the equipment provides the required cooling. The tank is preferably arranged so as to lie within an existing profile of the cooled equipment, and to be relatively small as compared to known cryogen tanks.
摘要:
A quench protection circuit for a superconducting magnet, comprises at least one heater associated with a corresponding coil of the superconducting magnet. The at least one heater is arranged to be driven by an inductor which is connected in series with it and is arranged to derive a voltage from variation in a magnetic field of the superconducting magnet. The at least one heater and the inductor are arranged in a series circuit which further comprises a non-linear positive temperature coefficient resistors.

A split cycle reciprocating piston engine includes a compression cylinder (2) accommodating a compression piston (4) and an expansion cylinder (12) accommodating an expansion piston (14). The compression cylinder (2) has an inlet port (30) for the admission of air and an outlet port (36) which communicates with a first path of a heat exchanger (5). The expansion cylinder (12) has an inlet port (52), which communicates with the first path of the heat exchanger (5), and an outlet port (56), which communicates with a second path of the heat exchanger (5) in heat exchange relationship with the first path. The method of operating the engine includes injecting a liquefied, non-oxidizing, non-combustible gas, such as nitrogen, into the compression cylinder (2).
