Abstract

195,266. Goodman, W. H., and Dubilier Condenser Co. (1921), Ltd. March 22, 1922. Condensers.-A condenser comprises sets of plates or units arranged radially around a. centre or axis, each set comprising a number of plates or units mounted together in block form and arranged substantially tangentially to concentric circles. The plates or units of high potential are preferably arranged adjacent the axis, those of low potential being arranged adjacent the periphery of the condenser. In the construction shown, a number of rings c are mounted coaxially on four rods b carried by the lid a<1> of the casing a, these rods forming low-potential terminals in parallel. The high-potential terminal is formed by an axial tube d, the tube and the high-potential lead being insulated from the casing by sleeves d<1>, d<2>. The tube d carries a number of polygonal collars c<1> in the plane of the rings c, the condenser elements e being clamped between the faces of the collars and corresponding faces c<2> on the rings c by screws c'. In place of the collars, independent blocks adapted to bed against the tube d may be provided for each of the sets of elements e. The rods b and rings c may be replaced by a frame which may be suspended within the casing or carried by its lower end, or the casing itself may be provided with internal seatings for the sets of condenser elements. In a modification, the supports at the outer ends of the condenser sets are dispensed with, and the condenser elements are threaded on rods extending radially at right-angles to the axis of thecasing. The high and low potential leads may be arranged at opposite ends of the casing.
