Abstract

516,664. Electron multipliers. BOSCH, F. J. G. VANDEN. June 2,1938, No. 31096/39. Divided out of 516,621. Drawings to Specification. [Class 39 (i)] The description and Figures are the same as those of Specification 516,621, the claims, however, refer to the arrangement by which the multiplier electrodes are surrounded by flanges serving as concentrating electrodes. Specification 488,661 also is referred to.
