Abstract: A selecting machine of the type commonly used for addressing mailed material from individual data-bearing cards, using tri-level logical comparator circuitry to compare the individual cards against an interchangeable master card. Both the individual and the master cards are perforated in files of holes longitudinal to the direction in which they are synchronously moved by the machine, the files of perforations being sensed by phototransistors connected in turn to the logic circuitry. For each potentially perforable site on the individual card, there are two corresponding locations on the master card, one of which when matched by a perforation on the individual card indicates nominal selection of the individual card, the other of which indicates positive rejection of the individual card, overriding any nominal selection, with rejection by default occurring if neither location on the master is perforated to correspond with a perforation at the equivalent site on the individual card.

Abstract: A selective imprinting machine of the type used for addressing mailed material, utilizing embossed card-sized media of the "credit-card" type having a matrix of perforations sensed for comparison against the master. The master is another perforated card with the perforations on both cards photoelectrically sensed. In one embodiment the cards move along a linear path, and in another they are carried on a rotating drum which also bears the master card. The media are placed on the drum by a rocker arm actuated by a cam driven by the drum, scanned simultaneously with the master for comparison and ejected tangentially from the drum to a receiver. A print signal is produced until inhibited by mismatch between the master and the individual embossed media. The elected media are imprinted against a receiving medium such as an envelope by a print roller, at the periphery of the drum, urged toward the periphery by a cam driven by the drum.
