Filed: 1943-10-26
Abstract: 570,694. Lathes. JEFFREE, J. H. Oct. 26, 1943, No. 17646. [Class 83 (iii)] [Also in Group XXIII] In the shaping of optical surfaces, for example, on lenses, mirrors or dies for the production of lenses from transparent plastics, the work-piece, roughly formed to the required surface, is rotated about its optical axis and acted upon by a reciprocating tool in the form of a template made of thin hard metal, the edge of which initially is shaped roughly to fit the surface, and the inclination of the template to the surface is so controlled in relation to its traverse that the edge, when the desired shape has been attained, continues to fit the surface at all parts of the traverse. A machine for carrying out the above operation comprises a table 10 carrying a pivot rod 12 with upright frame members 13 thereon, these in turn having pivoted thereto, on a rod 14, horizontal frame members 15 having a pivot rod 16 carrying two arms 17, to which the template 18, or a holder therefor, is secured, the lower preformed edge of the template resting on the preformed work-piece 19, which is carried by a holder 20 rotated about the optical axis of the work-piece. On the table 10 is a standard 21 carrying a bracket 211 on which is pivoted, at 212, a perforated rod 22 acted on by a spring 222 and receiving in a selected perforation one end of the rod 16. The table 10 has at one end thereof a spindle 101 carrying a slotted disc 24 having thereon an adjustable crank-pin 241, on which is mounted a carrier 23 ; the spindle 101 and the holder 20 are belt driven by a motor 35. Rotatable on the carrier 23 is a disc 27 driven, through gearing 39, 40, by the crank-pin 241, and on the disc is a pin 45 transversely adjustable in a slot 42 by a screw 44 ; the pin 45 has two locking washers engaging a slotted bar 28, which is coupled to the template 18 by a stirrup 30, with a universal joint 31. A pin 29 extending upwards from the carrier 23 engages the slotted bar 28 ; the throw of the pin 241 determines the stroke of the template and that of the pin-45 the change of position of the stroke, whilst the adjustment of the bar 28 on the pin 45 determines the average position of the strokes in relation to the axis of the workpiece. The template may operate by scraping the surface under treatment, or abrasive and lubricant may be applied ; for polishing, the template may have a flexible edge or an edge of leather or soft fabric.

Abstract: 754,169. Cathode-ray tubes. RADIO CORPORATION OF AMERICA..June 16, 1954 [July 10, 1953], No. 17724/54. Class 39 (1). [Also in Group XL (c)] Vibration of a grid adjacent the screen of a colour television tube due to voltage fluctuations induced on the grid and on an adjacent electrode at a different voltage, by load variations of the sources of voltage, is eliminated by making the voltage fluctuations of the electrodes equal or nearly so. Voltage fluctuations may be coupled from one electrode to the other, e.g. through a condenser, or suitable voltage fluctuations may be induced on one electrode by adjusting the regulation of the voltage source. The grid 24, Fig. 6, and screen 16 of a three-gun post deflection deceleration tube are connected to a 15 kv. voltage source and the grid 26 to a 20 kv. source. The 15 kv. source includes a voltage regulator tube 54. The voltage fluctuations of the 15 kv. source are increased to equal those of the 20 kv. source by reducing the efficiency of regulation. The filter 48, 49, 50 attenuates voltage fluctuations transmitted from the tap 47 of the voltage divider 52 to the grid of the tube 54. Voltage fluctuations may be fed from the 20 kv. source to the cathode of tube 54 through voltage divider 51 and filter 56. Voltage variations in the load current may be fed to the 15 kv. grid 24. The television tube may be of the post deflection acceleration type with a single grid associated with the screen 16, or of the type with a single gun and beam switching grids 104, 106, Fig. 11, in front of the screen 100. The grids are connected to a 5 kv. source 108 through impedances 114, 116 relatively high to the high-frequency switching voltages, but relatively low to voltage fluctuations due to load changes. The voltage fluctuations of the 20 kv source 102 for the screen 100 are coupled to the grids through a condenser 118.
