Abstract: 688,476. Typewriters &c. BURROUGHS ADDING MACHINE CO. Dec. 21, 1949 [Dec. 23, 1948], No. 32761/49. Class 100(iv) A machine controlled by record cards or sheets has two comparison control mechanisms and two printing sections one of which is normally disabled but is operated when the data sensed is identical with the data set up on one of the comparison control mechanisms; when the data sensed by the record cards compares with the other comparison control mechanism a segregating device 31 is operated to separate that record card from the others. The printing sections are similar to those described in Specification 674,343, one of which prints e.g. an address label for applying to publications being posted and the other prints, if required. a renewal notice on a further or separate label or envelope. The operation of the second printing sections is controlled from perforated data in the first four columns of a record card 22 and the selection of-the printing elements to form the characters in each printing head of both sections is controlled from the remaining columns. When the data in the first four columns, comprising e.g. a date of expiry of subscription for the periodical, is similar to a date set up on one comparison control mechanism by manually set dials A indicating the month and year of the periodical now being dispatched, the first print section operates to produce a label for the current issue but the comparison effects operation of circuits which cause a solenoid 33, Fig. 1, to operate and segregate the record card into a hopper 30 separating it from cards in hopper 29 which are used for the next issue. If, however, the date on the cards compares with date set up on the other comparison control mechanism by dials B, say two months ahead, circuits are operated effecting printing in the second section on the renewal notice and the record card is delivered into the normal hopper 29. The dial A has four sections each having two wipers 37, 38 which each bridge pairs of contacts 1D, 1R; 2D, 2R, &c., Fig. 7, wired in series with groups of relays E-G respectively, as shown in Fig. 9. According to the setting of the dials, operation circuits for the group of relays E; F, G, H are prepared corresponding to each of the four dials A so that when the perforations in a record card are sensed by the -four brushes 27 two relays in each group are energized according to the figure sensed in each column. If a numeral 1 is sensed by brush 27, Fig. 10, in the first columns of the record card, relays El and E2, Fig. 9, operate because contacts 1D, 2D have been closed by wipers 37, 38. Relays E1, E2 close contacts 3e and 5e, Fig. 12, so that relay E10 operates. Similarly when the code sensed agrees with the setting of the other three A dials, relays F10, G10 and H10 operate and when all four relays are operated a circuit is completed to the card deflecting solenoid 33 by contacts e10, f10, g10, h10. The holding circuit for relays E, F, G, H is broken at the completion of machine cycle by a gap in the sector c of commutator CM, Fig. 10. If the codes sensed in the four columns agrees with the setting of wipers 37, 38 on the B dials, pairs of relays in groups J, K, M, N are operated and in a like manner to the operation of relays E, F, G, H, further relays J10, KfO, M10, N10, Fig. 13, are operated closing contacts in series with a common return conductor of operating solenoids in the second printing sector which is thus made effective to print the renewal notice. The operation of the elements forming the various characters is performed in a similar manner to that described in Specification 674,343.
