DEFINITION

Classification: 505/211

Electrical energy storage device (e.g., accumulator, etc.), inductor, transformer, magnetic switch, magnetic ring, sphere, coil, or magnetic arrangement:

(under subclass 150) Device for storing electrical energy (e.g., accumulator, etc.), switching devices dependent on magnetism for operation, means for inducing current into wires or electrical storage devices, or magnetic ring or coil (i.e., which may include appended electrode, lead, or nominal refrigeration means); or organizations of magnets.

(1) Note. Merely reciting that a superconducting device or material is attached to a cryogenic refrigeration device or providing space or connection for flowing a cryogenic fluid will not be considered significant refrigeration structure unless structure is present that actually causes the refrigeration.

SEE OR SEARCH THIS CLASS, SUBCLASS:

163, for significant refrigeration system or device under subclass 150 containing a superconductor element (a) that operates as part of the system, such as for supplying electrical current or that participates directly in the cooling through a thermoelectric effect, or (b) that is present with the system as a device or material that is to be

cooled; or process of using (a) or (b).

220, for superconductor having metal connect, pad, connect structure, or patterned superconductor circuit.

230+, for superconducting wire, tape, cable, or fiber, per se, that can produce magnetic effects as well as conduct electricity.
