Abstract: 1,192,312. Corrugating; jointing. DIGITAL SENSORS Inc. 16 July, 1968, No. 33895/68. Headings B3E and B3V. [Also in Divisions B5, D1 and H1] A corrugating device, for particular use with screened tape-type electric cable, comprises a pair of small diameter corrugating rollers each of which intermeshes throughout its length with a toothed backing roller of larger diameter. The lower corrugating roller 64 and its backing roller 58 are mounted between bearing blocks 50 and 52 fixedly mounted within side frames 36, 37, 46 and 38, 39, 48 respectively, whilst the upper corrugating roller 72 and its backing roller 70 are mounted between bearing blocks 74 and 76 slidably mounted within the frames over pins carried by the blocks 50 and 52. Each frame is pivotably mounted about a bolt 40 and is provided with an adjusting screw 96 or 98, the lower end of which engages a slot in a member 90 or 92 carried by a slidable block and this enables the gap between the corrugating rollers to be adjusted. The corrugating rollers are driven through intermeshing gears 60 and 84 carried by the ends of rollers 58 and 70 respectively. The device is easily disassembled by pivoting the frames outwardly about bolts 40, thus disengaging the lower ends of the adjusting screws from the members 90 and 92. This leaves the blocks 74 and 76 resting upon blocks 50 and 52 from which they may easily be lifted to separate the upper and lower roller assemblies. The tape-type electric cable comprises a centre layer of plastic material in which the conductors are embedded and a pair of outer copper screening sheets, the sheets being bonded to the centre layer by a non-solidifying adhesive so that relative movement between the screening sheets and centre layer during the corrugating is possible thus alleviating deleterious stresses.

Title: Improvements relating to punching machines
IPC: B21D28/26
Filed: 1920-12-03
Abstract: 176,480. Adams, E. W., and Hilton, J. Dec. 3, 1920. Punching.-Relates to gauging- tops and consist in electricallyactuated and controlled stops, which are contained in recesses in the worktable and are raised into the operative position by solenoids controlled by a rotary selectorswitch which is rotated step-bystep by the punching-head. When current is supplied to the machine, it passes from the terminal n through the lead 6, contacts o, p, solenoid q and the contacts m, k to the terminal s. The contacts m, k are normally in engagement and are disengaged by the solenoid j when energized. When the solenoid q is energized it rocks the lever 7 about the pivot 8 to disengage the contacts o, p and engage the contacts t, u. Current then flows through the contacts u, t to the solenoid c or d, according to the position of the selector-switch e. The solenoid c raises the stop a and closes the switch v so that current flows by lead 2 to the solenoid j, which pulls the contact k out of engagement with the contact m and into engagement with the contact m<1> so that current flows through the solenoid j as long as the contacts t, u are in engagement. When the contacts o, p are out of engagement and the switch 3 is closed by the descent of the punch, current flows from the terminal n through a resistance 5, the solenoid q and lead 4 to the terminal s. When a solenoid such as c, Fig. 4, is energized, it attracts its armature 10 and by means of a rod 11 and bell-crank 12 rocks a spindle 14 which, by means of a lever 15, Fig. 5, raises the stop a. The stop has a pivoted piece 16, which, when the work presses against it, swings and engages the bevelled end of a rod 17, pushing it endways to rock the lever 18, Fig. 4, and open the switch v. The parts are returned to their original positions by springs, whereupon another stop determined by the selector is raised, by a similar sequence of operations.
