摘要： A logic system for preventing the loss of information which may occur when synchronization between a transmitter and a receiver is momentarily lost because data is being transmitted from a central computer or a telegraph sender to a plurality of buffer storage units at a rate greater than the rate at which the data can be removed from the buffer storage units for printing. At some time prior to the actual loss of information, a set of particular circuit conditions will exist. This set of conditions is used to establish a threshold logic state and the attainment of this state indicates that a loss of information is anticipated. A logic circuit is used to monitor synchronization, to detect the attainment of the threshold logic state and to cause the generation of a restraint signal in response to the attainment of the threshold logic state for temporarily inhibiting the further transmission of data until synchronization is restored.

摘要： A card reader capable of automatically reading coded information from cards of at least two predetermined widths, the information being encoded in information fields that may vary in the length of columns and rows from card to card, such fields being referenced with respect to two predetermined orthogonal edges on each card. Movable stop fingers and a guiding edge facilitate aligned insertion of a card with respect to the two orthogonal edges. When a card is being advanced through the reader past a reading station, a circuit that is triggered by a column count wheel generates a signal each time that a column of information is in position to be read. This circuit is inhibited by switches that respond to cards of predetermined widths when the trailing edge of a card passes their position, the location of the switches having a predetermined relationship to the last line of coded information to be read on the individual type of card. The circuit can also be inhibited by a signal generated by an encoder upon its detection of an end of text code in the information field. The card reader is shut off at the end of each read cycle by an independent switch responsive to the trailing edge of all cards inserted into the reader.

摘要： A print train of predetermined length and comprised of a plurality of type carrying blocks is provided with an increased number of hammer impactable type characters to thereby enable the realization of significantly accelerated printing speeds, the type blocks being individually and alternately driven to advance a toothed belt to which the blocks are separately coupled around a pair of rotatable sprockets, said accelerated printing speeds being realized without an accompanying degradation of printing quality resulting from the closer spacing of the adjacent characters, means being provided to shield the characters adjacent to an impacted character against the striking force of the hammer associated with such impacted character.

摘要： Printing apparatus wherein a webbed medium is intermittently fed from print line to print line between a row of actuatable print hammers and a continuously displacing set of print characters. Between intermittent advances the webbed medium is impacted by selected ones of the print hammers to print a line thereupon, such impact being effective to engage the impacted area of the webbed medium with the continuously moving print characters, thus urging the webbed medium out of a predetermined alignment with the print hammers. Restraining means prevents such shiftable movement by immobilizing the webbed medium in opposition to the undesirable influence of the moving print characters.
