A copy-milling machine has a carriage slidable in any direction in a plane, a tracer head mounted on the carriage opposite a template holder of the machine and engageable with an edge of a template held therein, a mechanism for actuating the carriage comprising a slideway drivably rotatable about a fixed axis at right-angles to the plane of movement of the carriage, a block slidably mounted in and biased towards an end of the slideway and journalled to the carriage eccentrically to the axis of rotation so as to bias the carriage and tracing head in the longitudinal direction of the slideway, movements of the tracer head being reproduced in the movements of a milling tool. In apparatus for machining spectacle frame blanks 60 to the profile of a template 24, there is provided a carriage 12 slidably mounted for universal movement in one plane on a longitudinal guide rail 18 supported on a pair of transverse guides 2, the carriage 12 supporting a tracer 23, 23<SP>1</SP> and milling tool head 50 with tool 51. A rotatable disc 46 with a diametrical slideway 45 carries a slide block 43, spring-loaded by a spring 49 to an eccentric position relative to the axis of rotation and journalled to the carriage 12. Tracer roller 23<SP>1</SP> is thus biased into engagement with the template 24, rotation of the disc 46 causing orbital movement of the carriage 12, tracer 23 and milling head 50 according to the profile of the template. Two machines may be set up in mirror image relationship across the plane O to machine the two openings of a blank 60 simultaneously. Driving motors 52 for the milling tools may then require to be offset from the tools, drive being effected through flexible shafts 53. The transverse guides 2 each comprise a cover-plate 10 bolted to a runner 8 mounted by needle bearings 9 in a channel comprising side plates 4 and bottom plate 5 the side plates 4 and runner 8 having complementary longitudinally extending V-projections and grooves.

Abstract: 565,283. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). March 24, 1943, No. 4772. [Class 40 (v)] A counter circuit comprises a pair of currentcontrolling electronic discharge devices with interlocking controls so that the impedance of one device is at a high value and the other is at a low value so that a two equilibrium mode circuit is obtained and is associated with a double-throw electronic switching device such. that an incoming impulse is applied to one or other of the actuating connections dependent on the state of the apparatus and changes the state of equilibrium. The Figure shows an arrangement in which switch tubes 11, 12 control the tubes 13, 14 which are so cross-coupled as to have two states of equilibrium. The auxiliary grids F1, F2 of the switch tubes 11, 12 are coupled to the grids D1, D2 respectively of the tubes 13, 14 through resistances 32, 33 and condensers 34, 35 so as not to be affected by sudden voltage changes and a switch 41 is provided to ensure that initially tubes 11 and 13 are conducting. The input 15, 16 is fed with positive impulses, the first of which renders tubes 12, 14 conductive and the next tubes 11, 13 conductive and so on. Diodes 37, 38 are provided to maintain the grids D1, D2 at their negative potentials after each impulse. Alternatively, the anodes of the valves 11, 13 and 12, 14 respectively may be coupled and the driving pulses may be applied to the grids F1, F2 or D1, D2.
