Title: Method and apparatus for applying markings to flat articles
IPC: B41F33/00
Filed: 1962-07-27
Abstract: 962,776. Typewriters &c. STANDARD TELEPHONES & CABLES Ltd. July 27, 1962 [July 31, 1961], No. 28981/62. Heading B6F. [Also in Division B8] Coded markings are applied to flat articles such as envelopes by placing each envelope on a moving conveyer 3, perforating a belt 6 with a code to be applied to the article, moving the perforated belt adjacent to the envelope at the same speed as the envelope, and applying a marking to said envelope through said perforated belt. Each envelope 1 is fed by a device 2 into the field of vision of an operator who reads the destination and feeds the corresponding code which is assigned to the destination to a device 8 for perforating the belt 6 by means of a keyboard, not shown. As the last code signal is keyed in an arresting device is unlatched and the envelope 1 falls on to the belt 3. A pair of belts 5 grip the upper part of the envelope and move it to a position at which an ink roller 9 is temporarily pressed against the belt 6 and ink passes through the holes forming the code on to the envelope. The belt 6 is fed forwardly by sprocket wheels 12 and the feed of the belt is controlled by light devices 4 and 17. The belt 6 is dried in a device 11. The feed mechanism for the belt 6 is controlled by photo-electric devices 4 and 17.

In an automatic telephone system multi-metering is controlled by the appropriate one of a number of common impulse generators, one per tariff, which sends impulses to a link circuit after the called party answers, the first said impulse operating means connected to the link circuit so that subsequent impulses cause the stepping of the calling party's meter to which the link is extended, the meter taking another step when the connection is released. The outgoing junction repeater shown includes a switch TV which connects up the appropriate contacts 9 and off-normal contacts 10, 11. On seizure R1 pulls up followed by R2, but the polarized R5 remains down. The register then sends an extra digit, indicative of the tariff for the call, in the form of battery impulses on a1 and b1 to which R11 responds, stepping TV to the appropriate position. On the reply of the called party R5 responds to the usual battery reversal on a2, b2. This results in the operation of R6, R7 (which repeats the battery reversal over a1, b1), and R8 (which energizes the meter SR). The first impulse from TV brings up R9, R10 coming up in series at the end of the impulse, whereupon R9 is released. As R7 remains up during these momentary disconnections, SR is not released and consequently does not step. When R9 responds to each subsequent impulse from TV, R7 releases for the duration of the impulse and SR is stepped. When the parties hang up R1 and R5 release and all the relays and TV restore, SR taking another step in the process.
