Abstract
760,323. Velocity-modulated tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 18, 1954 [April 1, 1953], No. 9119/53. Class 39(1). [Also in Group XXIV] A spring-loaded cam mechanism for converting an angular or rotary movement into a small axial movement is shown applied to a tuning mechanism for moving the wall of a klystrontype resonator, and comprises a fixed element 10 having a conical surface opposing a spirallygrooved element 9 which is rotatable on an axially-movable sleeve 8, one or more balls or other followers being interposed between the elements so that rotation of the element 9 causes movement of the followers along the spiral groove, their consequent radial movement over the fixed conical surface causing axial movement of the element 9. The axial movement is conveyed through a thrust bearing to the non-rotatable sleeve 8 which is fixed to a sleeve 7 coupled to the movable resonator wall (not shown). The mechanism may be axially loaded by a plurality of springs 16 interposed between a cooling fin on the sleeve 7 and a fixed bracket 3, or alternatively by a central disc or other spring. The element 9 may be rotated by a cap 17 or by gearing. The spiral groove is preferably of arcuate section to receive the ball followers. If the groove is flatbottomed the followers may be frustro-conical. Where three followers are provided they are held in equidistantly-spaced radial slots in a cage and preferably co-operate with three separate spiral grooves. If three followers are employed with a single spiral groove they may be of different diameters to prevent tilting. The limits of rotation are defined by pins in the ends of the grooves. It is stated that the conical surface may be replaced by a curvilinear or other surface, that the grooves may be other than true spirals, and that the grooves may be formed on the conical surface. The mechanism may be employed in a lifting device or a press. According to the Provisional Specification a conical-surface element similar to the element 10 is axially moved by rotation of a spirallygrooved element similar to the element 9.
