Abstract
Abstract Liquid metal collector is provided with a rotatable cup member and a stationary conductor blade. A floating ring is positioned generally intermediate between the blade and cup member and is immersed in the liquid metal such that is effectively reduces the rotational velocity of the liquid metal relative to the ring members by approximately one-half over the surface of the conductor blade. By so reducing the velocity of the liquid metal, power losses are reduced and antierosion characteristics are improved. A plurality of floating rings may be employed which will reduce the relative velocities even more.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
84 words
In a conductive liquid collector for use in a dynamoelectric machine having a stationary conductor blade immersed in a rotating volume of conductive liquid contained within a rotating cup member, the improvement comprising: at least one floating ring member positioned between the conductor blade and the cup member so constructed and arranged that when the cup member is up to speed, the ring member floats freely in the conductive liquid substantially reducing the velocity of said conductive liquid over the surface of the blade.
Claim 2
Dependent Claim
84 words
In a conductive liquid collector for use in a dynamoelectric machine having a stationary conductor blade immersed in a rotating volume of conductive liquid contained within a rotating cup member, the improvement comprising: at least one floating ring member positioned between the conductor blade and the cup member so constructed and arranged that when the cup member is up to speed, the ring member floats freely in the conductive liquid substantially reducing the velocity of said conductive liquid over the surface of the blade.
Claim 3
Dependent Claim
27 words
A conductive liquid collector According to claim 1 wherein the floating ring member has a cup-shaped cross section conforming generally to the outline of the blade surface.
Claim 4
Dependent Claim
41 words
A conductive liquid collector according to claim 1 wherein the floating ring member is out of contact with the cup member and the stationary blade so that an uninterrupted current path is provided through the liquid metal around the ring member.
