Title: Method of and apparatus for renewing paper webs in printing presses
IPC: B65H19/18
Filed: 1937-03-11
Abstract: 489,873. Feeding webs. GIBSON, W. March 11, 1937, No. 7175. [Class 100 (i)] A method of splicing the web of a replacement roll 9 to a running web 4a feeding a printing-press, without reducing the speed of the press during splicing, consists in effecting contact between the roll 9 and the running web to bring the peripheral speed of the roll 9 substantially to the linear speed of the running web, and applying solvent to dry adhesive previously located on the outer surface of the leading end of the replacement web forming the roll 9 whereby the replacement web is spliced to the running web 4a when the moistened adhesive contacts with the running web. Three web rolls are mounted on a spider reel which can be rotated by means of a motor. When the running roll 4 is nearly exhausted, the reel motor is started by depressing a press button 5, and the motor circuit is maintained by conducting segments 7 fixed to the reel-stand and bridged by a moving contact bar 8 in parallel with the press button 5. When the replacement roll 9 contacts the web 4a, the bar 8 leaves the segments 7, the reel stops, and the roll 9 is brought up to the required speed by the web 4a. A press button 11 is now depressed which completes an electric circuit through a switch 13 on the spindle of the roll 9, and conducting segments 14, to a solenoid 12 which actuates a lever 19 to press a moistened roller 18 on the periphery of the roll 9 to moisten the dry adhesive thereon. The dry adhesive is provided on labels 3, and the conducting portion 15 of the switch 13 is so arranged in relation to the labels 3 that the roller 18 contacts with the roll 9 slightly ahead of the labels 3. When the moistened labels meet the running web 4a they adhere thereto and the replacement web is carried to the printing-press. The establishment of the circuit through the switch 13 also energizes a solenoid 20 which, through a dash-pot delayed switch 21, and solenoid 22, operates a cutter 23 to sever the running web 4a. The solenoid 22 also closes a switch 24 in series with the press button 5 so that the reel stand is again rotated until the bar 8 leaves the lower ends of segments 7a. A backing-roller 10 maybe employed to assist engagement with the running web. Each web roll is prepared for the splicing operation by forming two tails on the end of the web, and securing the tails by easily tearable tabs such as described in Specification 422,211. Alternatively, the end of the web may be treated as described in Specification 452,328, or may be secured by tallow or other weak adhesive. Finally, labels 3 having dry adhesive on both sides are applied to the tails.

Patent GB-579685-A (GB)
Title: Improvements in or relating to thermionic amplifiers
IPC: H03F3/32
Filed: 1944-04-24
Abstract: 579,685. Valve amplifying circuits. MANSFORD, H. L. April 24, 1944, No. 7623. [Class 40 (v)] In an amplifier cumprising a number of pairs of valves, the cathodes of each pair being connected to a common point, and the anodes to a common point while the grids are fed in push-pull, connections are made between the common points to which anodes and cathodes of different pairs are connected such that the anode circuits of the pairs are effectively in series across the power supply. A push-pull input, applied to the grids of a valve pair 1, 1a causes amplified voltages to appear at the anodes, the current passing through the pair remaining constant so that the potential of the cathodes of valve pair 7, 7a is unchanged.' The grids of valves 7, 7a are fed in push-pull from the anodes of valves 1, 1a and, in a similar manner, the output pair of valves 12, 12a are fed from the anodes of valves 7, 7a. Potentials applied in-phase to valves 1, 1a cause changes in the total anode current of the pair, the amplifier gain thereby being reduced to that given by a valve 1 feeding into an anode load, tapped to provide an output voltage. Since later pairs of valves may pass larger currents than the earlier stages, the difference in current may be passed through resistances 24, 25 which may be replaced by further amplifiers of this type. A potentiometer 21 supplies bias to valve 1a and also through the input circuit to valve 1. The grid of one of valves 1, 1a may be earthed, the input being applied to the grid of the other valve, the feed to the first valve being supplied over the common cathode lead 20. The grid of any valve in the chain may be resistance opacity coupled or transformer coupled to the anode of the preceding valve or. cross-connected to a preceding valve in the opposite chain. To provide the correct bias, a resistance may be connected in the grid lead to a valve, a second resistance being connected to a point of constant potential. A resistance may also be connected in the common cathode lead of any pair to adjust the bias. The resistance 20 may be replaced by a pentode, the bias being varied to alter the current through valves 1, 1a and the gain of the amplifier. Further valves may be similarly connected to valves 1, 1a with a pentode in the cathode lead and the anodes connected to the anodes of valves 1, la. Accordingly as one or other of the cathode load pentodes is rendered conducting, signals applied to valves 1, la or the additional valves will be amplified.
