Abstract
664,663. Travelling-wave tubes. MULLARD RADIO VALVE CO., Ltd., and ROBINSON, N. W. Aug. 30, 1950 [Sept. 1, 1949], No. 22697/49. Drawings to Specification. Class 39 (i). In a travelling wave tube, the wire helix is supported at a few points in each turn by a surrounding tube of, e.g. square or triangular cross-section, whereby the effect of irregularities in the supporting dielectric tube are minimized, and space is provided for the extra thickness at welded joints. Glass or quartz tube may be shaped by driving a suitable mandrel through heated circular tubing. Alternatively a " V " notch may be machined in ceramic strip, and a further ceramic strip secured over the open " V " to provide a triangular tube.
