Abstract

770,560. Condensation pumps. BOCK, W. Oct. 27, 1954 [Oct. 29, 1953], No. 31010/54. Class 71 In a diffusion pump, heated surfaces 29 and cooled surfaces 25 are provided in the inlet passage 15 to the pump. The surfaces 29 are concave and electrically heated, and the surfaces 25 are inclined. from the surfaces of the passage 15 towards the axis in the direction of flow at an angle up to 60 degrees and are cooled by cooling agent flowing through pipes 27. The pipes 27 support the surfaces at the axis. Specifications 756,373 [Group I], and 766,192 are referred to.
