Title: Improvements in or relating to electronic tube clamp and shield
Inventor: WOODS LEROY RALPH
IPC: H01J19/66
Filed: 1954-06-11
Abstract: 748,253. Thermionic valves. INTERNATIONAL ELECTRONIC RESEARCH CORPORATION. June 11, 1954, No. 17228/54. Class 39 (1). [Also in Group XL (c)] A metal screening container for an electronic tube has a multiplicity of spring contact elements arranged in a uniform pattern over its inner surface, resiliently engaging the exterior of the tube in heat transfer relationship. These elements may be formed as a number of separate units 31, Fig. 5, of spring copper with a black cadmium finish. Each unit is cut so as to have a series of inwardly bent tongues 35, alternating with a series of outwardly extending tongues 34. The units have a generally arcuate shape, so that when they are secured to the inner side of the container 22, both series of tongues bear resiliently against the tube 27. The container 22 has four rectangular openings 29, Fig. 4, separated by solid portions 30. When one unit as in Fig. 5 is attached to each solid portion 30, the tube 27 is virtually enclosed and supported by the multiple pattern of spring contact tongues. Instead of four separate units, the pattern of spring elements may be formed as a single sheet, Fig. 9 (not shown), which is then rolled up and inserted inside the container. A helical spring 26 engaging the top of the tube may also be provided. The arrangement is especially suitable for tubes which may have to operate under conditions of excessive vibration, and the direct contact on the tube of a large number of metal tongues also allows the dissipation by direct conduction of a substantial quantity of heat, while the generally open construction facilitates air circulation. The container 22 is secured in a readily detachable manner to a holder 11 on a support or chassis part 12.

[Also in Division F2] In a method of manufacturing a shaft and a sleeve of a gas lubricated journal bearing, the two members are machined circular, one of the members is radially stressed to deform its bearing surface and machined circular in this stressed condition so that when unstressed there results a lobed bearing surface. In Figs. 1 and 2 is shown a pair of clamps 5 and 6 for radially stressing a bearing sleeve 2 in such a manner as to form a two lobed internal bearing surface; suitably modified clamps will give any desired number of lobes. Alternatively, the the shaft may be internally stressed and externally machined to form a lobed shaft. The preferred machining operation is honing for both members, as roundness tolerances are of the order of 0.5 X 10<SP>-4</SP>, and working clearances are about 15 x 10<SP>-4</SP> for a 1 inch diameter shaft. The lobing is of a small order, for a 1 inch diameter shaft a two lobe surface, which will be approximately elliptical the major and minor axes may be 1.0007 and 1.0002 inches. The required pre-stressing for a given lobing is determined, and checked by using air gauges to check maximum and minimum diameters as the stressing clamps are tightened. Fluid pressure may be used instead of clamps.
