Title: Improvements in and relating to a method and apparatus for manufacturing lead-through conductors in three parts for electronic valves
IPC: H01J9/28
Filed: 1963-09-11
Abstract: 1,035,788. Making lead-through conductors, welding by pressure. W. MÍTZ. Sept. 11. 1963, No. 35797/63. Headings B3A, B3E and B3R. A method of making three-piece lead-through conductors for pressure discs of electronic valves in which sets of different wires are fed to cutting devices from two opposite sides and the severed lengths are held in electrically conductive clamps to successively weld the ends together comprises forming a double length of contact pin from one of the wires, breaking the pin by heating the centre portion thereof and pulling it apart by way of the clamps to form two contact pins which are each coaxially welded to two other wire lengths to form the three-piece conductors. Nickel wire 6, 1 mm. diameter from reel 1, 0À4 mm. copper clad wire 7, 9 from reels 2, 4 and 0À5 mm. nickel wire 8, 10 from reels 3, 5 is advanced to stops and lengths 21-25 simultaneously cut therefrom and collected in hoppers 26-30. The lengths are subsequently gripped, by electrically conductive clamps, in coaxial alignment, the clamps 35, 36, Fig. 2 (not shown), grip the length 21 which is inductively heated and are moved apart to sever the length into two equal contact pin lengths. The clamps 35, 36 then move the ends of the pins into contact with the ends of the lengths 22, 24 held by clamps 31, 33 and a current impulse through the clamps effects welding of the ends, subsequently the clamps move the ends of the lengths 22, 24 into contact with the lengths 23, 25 to similarly weld the lengths together. Finally a pair of grinding wheels produce a truncated cone form on the ends of the pins 21 and the clamps open to drop the completed assemblies into hoppers where they are checked for length, welding and size of weld by electronic and optical means and are subsequently electronically counted and automatically packed in boxes. The clamp movements may be controlled by electronic or mechanical means, such as cams.

Abstract: 906,126. Film loop restoring mechanism. BELL & HOWELL CO. Oct. 24, 1960, No. 36466/60. Class 97 (1). In a projector wherein the film forms a loop between continuous take-up means and intermittent feed means, there is provided, against the possibility of the film loop being lost, a loop restorer comprising a pivotally mounted arm having a film engaging shoe, the said arm having an idle position intermediate to an actuated position, to which it is brought by the tensioned film if the loop is lost, and, on the opposite side of the said intermediate position, a restoring position to which it is brought by resilient camfollower means carried by the arm and movable into the path of a continuously rotating cam when the said arm is brought by the film to its said actuated position. As shown in Figs. 2 and 5, an arm 16 rigid with a pivotable pin 18 has a laterally extending shoe 15 which is engageable by the film 11 when the latter becomes tensioned to pivot the arm 16 upwards. Also rigid with pin 18 is an arm 22, to which is secured a leaf spring 24, and upon being pivoted as described into the dotted position shown in Fig. 5, strains spring 24, the upper end of which bears against an eccentrically revolving cam disc 31 continuously driven from the camera drive mechanism. When the least eccentric portion 31b (dwell portion) of the cam disc moves past spring 24, the tip of the latter escapes over the disc edge then to be constrained by the flange 31a. Continued rotation of the cam eventually to bring the lobe of the cam to bear against spring 24, as shown in full lines, produces pivoting of arm 22 in a sense opposite to the original pivoting into the full line position shown until the portion 22a abuts against part of the projector housing 20a. Arm 16 is thereby pivoted into the lowest position shown dotted in Fig. 5, thus pulling down the film to form a loop. If, at this time the film is held by the film feed mechanism, tearing of the film under the downward force of the shoe 15 is prevented by the resilience of spring 24. When the loop has been restored and the pressure of the film on shoe 15 released, arms 22 and 16 are returned to their idle position by spring 42.
