Title: Improvements in machines for generating curved surfaces
Inventor: GUNNING WILLIAM ALFRED
IPC: B23B5/40
Filed: 1952-04-09
Abstract: 704,134. Planing. AMERICAN OPTICAL CO. April 9, 1952. No. 9144/52. Class 83 (3) A machine for generating curved surfaces on laps for lenses comprises first and second members 20, 43 for supporting a tool and workpiece and mounted for oscillation about perpendicular axes, means for adjusting the second member 43 to and from the axis of the first, control means for energizing and de-energizing means for imparting swinging movement to the second member; and control means limiting the movement of one of the members to that necessary to complete the surface to be generated. The yoke 20 is supported by two uprights 16, 17 on the base 15. A slide 22 may be traversed on the base by a manually-operated screw 27 and carries an extension plate 29 to protect the slideways from cuttings &c. A gib 21 locks the slide 22 in adjusted position. The tailstock 43 is adjustable along slideways 42 on a plate 34 which is angularly adjustable on the slide 22 by a worm 35 on a shaft 36. The tailstock is locked by a gib 49 and screws 51. Work-holders.-The lap 54 on a holder 53 is clamped in a split socket 52 on the tailstock. Cutter-releasing meahanism.-The cutting tool 58, Fig. 16, is secured in a clapper box 139 pivoted in a holder 134 which is clamped in a split socket in the yoke 20. Generating.-The yoke 20 is oscillated by an adjustable crank and connecting rod 63 and a link 64. The tool is set at the required radius by a gauge 65, Fig. 9, located by a recess 72 in the yoke 20. If a spherical surface is required the slide 22 is adjusted to bring a plate 77, Fig. 11, into coincidence with a plate 76 on the bed, the plates being located so that the pivotal axis of the plate 34 then passes through the axis of the yoke. The slide can be locked in this position by a peg 82 engaging recesses in the plated 76, 77. In operation, an electric motor 132 rotates the crank to oscillate the yoke and also actuate a pawl 78 to advance the shaft 36 and so move the lap step-by-step in a circular path. For producing a concave lap the tool and lap are inter-changed. For setting-up in this case, the tool is set according to an L-gauge 86, Fig. 10, having a peg 88 engaging a recess in the tailstock, and the tailstock is then adjusted to the required radius by indicia 90 on the plate 34, and 91 on the gauge 65, which is located by a recess 89. The production of spherocylindrical surfaces is also described, the slide 68 of the gauge 65 then being used in co-operation with a mating peg 93 on a ledge 92 on the machine base. For larger radii of curvature the yoke 20 may be re-adjusted through 180 degrees. Stop motions.-In order that the machine may be stopped automatically as soon as a surface is finished, a micro-switch 127 is actuated by a follower 120 and a cam 113 which turns with the plate 34. The cam 113 is raised or lowered according to the initial adjustment of the tailstock by a block 105 on the tailstock which actuates a lever 102 connected to a lever 104 bearing on a plunger 106 carrying the cam.

Abstract: 576,804. Valve relay circuits. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation.). May 22, 1944, No. 9824. [Class 40 (v)] In a circuit for translating received A.C. impulses into operations of a relay contact, the beginning of each impulse fires a cold-cathode tube to energize the repeating relay and another relay which extinguishes the tube and alters its circuits so that the end of the impulse also fires the tube to energize a third relay which brings down the two former relays (which have hitherto been locked) and so again extinguishes the tube and terminates the repeated impulse. As shown, the rectified signal voltage developed across a resistance r2 is applied in series with the voltage of a potentiometer, P2 fed from a constant-current source to the electrode e1 which thus acts on the control anode. The resulting main discharge brings up the repeating relay Sr and an auxiliary relay Ar which extinguishes the tube and charges its circuits so that e1 becomes the cathode and the signal voltage is applied to e2 in opposition to the bias voltage of a second potentiometer P, which is such that when the signal ceases, the tube fires and Br brings down the other relays to restore the initial conductors. In an alternative arrangement, Fig. 1 (not shown), a single potentiometer with different tappings takes the place of the potentiometers P1, P2 and the discharge always takes place in the same direction.
