    Abstract: 46,156I SOLID BRUSH CURRENT COLLECTION SYSTEMS A solid brush current collecting system for dynamoelectric machines which selectively uses compatible materials in different applications for the moving and stationary contact members. Brushes of different compositions are disclosed and the current transfer and collecting members are operated in an inert gas atmosphere, such as carbon dioxide, containing a vaporous organic substance to achieve operation of the current collecting system at higher temperatures, higher velocities and higher current, densities than is possible with conventional systems. Low friction and low wear rates are in part achieved by operating the contact members in a low temperature environment.
