Claim 3

A rotor pole for cryo-alternators according to claim 1, wherein said fluid-tight channels include separate longitudinal channels provided between the bottom of the slots and said winding through which the cryogenic fluid flows in opposite directions, and in that said longitudinal channels are interconnected by a plurality of transverse passages arranged through the winding, between the winding and the slot-closing wedge, and between the winding and the slot edges.

Claim 4

A rotor pole for cryo-alternators according to claim 1, wherein said group of slots are provided in the form of a network pattern in an axial plane of the rotor body.

Claim 5

A rotor pole for cryo-alternators according to claim 1, wherein said winding is formed as a plurality of stacks of band-like conductors disposed in said slots, said stacks of conductors being separated by insulating members.

Claim 6

A rotor pole for cryo-alternators according to claim 4, wherein said fluid-tight channels include a plurality of passages for cryogenic fluid disposed between said stacks of conductors from the top to the bottom thereof, an outer chamber adjacent said wedge communicating with each of said passages, and an inner chamber divided into a plurality of longitudinal channels communicating with respective ones of said passages.

Claim 7

A rotor pole for cryo-alternators according to claim 5, wherein said group of slots are provided in the form of a network pattern in an axial plane of the rotor body.

Claim 8

A rotor pole for cryo-alternators according to claim 5, wherein four stacks of conductors are provided in said slots, said stacks being arranged in first and second pairs on respective sides of a central insulating member, a pair of passages being formed on respective sides of said central insulating member and an additional pair of passages being formed between said respective pairs of stacks and the sides of said slot.

Claim 9

A rotor pole for cryo-alternators according to claim 7, wherein said inner chamber is divided into three adjacent longitudinal channels, the outer longitudinal channels communicating with respective ones of said additional pair of passages and the central longitudinal passage communicating with said pair of passages on either side of said central insulating member.

Claim 10

A rotor pole for cryo-alternators, comprising a rotor body having formed in the surface thereof a plurality of continuous fluid-tight channels consisting of a continuous group of slots surrounding the axis of the rotor body, wedges fixedly secured to the upper part of the slots for forming the fluid-tight channels within the rotor body, a winding disposed within the fluid-tight channels, and perforations in the rotor body for connecting the fluid-tight closed group of slots to the outside of the rotor body for providing a flow path through which a cryogenic fluid flows.

Claim 11

A rotor pole for cryo-alternators, comprising a rotor body having formed in the surface thereof a plurality of continuous fluid-tight channels consisting of a continuous group of slots surrounding the axis of the rotor body, wedges fixedly secured to the upper part of the slots for forming the fluid-tight channels within the rotor body, a winding disposed within the fluid-tight channels, and perforations in the rotor body for connecting the fluid-tight closed group of slots to the outside of the rotor body for providing a flow path through which a cryogenic fluid flows.

Claim 12

A rotor pole for cryo-alternators according to claim 9, wherein the winding is disposed within the fluid-tight channels so as to provide flow passages for the cryogenic fluid between the bottom of the slots and the winding, between the winding and the slot-closing wedge, and between the winding and the slot edges.

Claim 13

A rotor pole for cryo-alternators according to claim 9, wherein said group of slots are provided in the form of a coil-like pattern extending in an axial plane of the rotor body.
