Device for separating gas bubbles from a liquid

Claim 2

A superconducting magnetic coil in a cooling bath of liquid helium, comprising a superconducting magnetic coil consisting of several superimposed disc windings with a vertical axis, said disc windings are permeable to said liquid helium, a device for separating gas bubbles contained in said liquid helium from said liquid helium situated between said superimposed windings of the magnetic coil, said device comprising several plates diagonally to the direction of the gas bubble movement in the liquid, said plates extending essentially parallel to each other and provided with openings arranged above each other, so that the openings of one plate are displaced from the openings of the adjacent plates, the openings on the plate side facing into the direction of the gas bubble movement are enclosed by material protrusions and the areas of those plate sides which are between said openings act as coherent gas collecting and diverting areas, thereby preventing gas bubbles from contacting said coil.

Claim 3

A superconducting magnetic coil in a cooling bath of liquid helium, comprising a superconducting magnetic coil consisting of several superimposed disc windings with a vertical axis, said disc windings are permeable to said liquid helium, a device for separating gas bubbles contained in said liquid helium from said liquid helium situated between said superimposed windings of the magnetic coil, said device comprising several plates perpendicular to the direction of the gas bubble movement in the liquid, said plates extending essentially parallel to each other and provided with openings arranged above each other, so that the openings of one plate are displaced from the openings of the adjacent plates, the openings on the plate side facing into the direction of the gas bubble movement are enclosed by material protrusions and the areas of those plate sides which are between said openings have a smooth surface and act as coherent gas collecting and diverting areas, thereby preventing gas bubbles from contacting said coil.

Claim 4

A superconducting magnetic coil in a cooling bath of liquid helium, comprising a superconducting magnetic coil consisting of several superimposed disc windings with a vertical axis, said disc windings are permeable to said liquid helium, a device for separating gas bubbles contained in said liquid helium from said liquid helium situated between said superimposed windings of the magnetic coil, said device comprising several plates perpendicular to the direction of the gas bubble movement in the liquid, said plates extending essentially parallel to each other and provided with openings arranged above each other, so that the openings of one plate are displaced from the openings of the adjacent plates, the openings on the plate side facing into the direction of the gas bubble movement are enclosed by material protrusions and the areas of those plate sides which are between said openings have a smooth surface and act as coherent gas collecting and diverting areas, thereby preventing gas bubbles from contacting said coil.

Claim 8

The device of claim 4, wherein the material elevations are formed through insets in the openings of the plates.

Claim 9

The device of claim 2, wherein the gas collecting and diverting areas formed as depressions in the plate surfaces are opposed to the direction of the bubble movement.

Claim 10

The device of claim 2, wherein the depressions annularly surrounding the openings intersect and increase in depth in the direction of the gas withdrawal.

Claim 11

The device of claim 2, wherein channels whose depth increases in gas diverting direction are at the plate surfaces, between the openings.

Claim 12
