Abstract: A dryer drum for a paper making machine with a shell and end heads and steam delivery means and a plurality of headers extending axially and uniformly circumferentially spaced a relatively short length each carrying a row of dipper straws projecting adjacent the inner surface of the shell with the headers fixed to the shell surface and flexible tubes connecting the headers to a main conduit for removal of the condensate.

Abstract: A motor vehicle alternator consisting of a stator assembly secured in a wheel which is journalled on an axle of the associated vehicle. Also rotatably arranged in the wheel concentrically within and in operative relation with the stator assembly is a field assembly, energized from the vehicle battery by means of a contact brush on the shaft engaging a slip ring on the rotary field assembly. The field assembly is gearingly driven by the wheel to rotate in the opposite direction with respect to the wheel, by means of radially journalled bevelled gears supported on the shaft and meshing with respective coaxial bevelled gears on the wheel and the field assembly. Output from the stator assembly is by means of respective brushes on the wheel and the shaft engaging opposite sides of a slip ring carried by the rotary field assembly. In a modified form, the field assembly is fixed relative to the shaft and the stator assembly is secured in the wheel and rotates around the field assembly.
