Abstract: The inventive ink jet printing system is driven from a repertoire data storage medium such as perforated tape or cards, magnetic tape or cards, or the like, on which the stored data may be changed, updated, increased or decreased, or deleted in whole or in part. The data read from this storage medium is fed into a microprocessor which directs a ganged multiplicity of ink jet printing heads, to simultaneously printout a plurality of lines of type. A transport mechanism picks up and feeds paper, magazines, or the like through a printing station where the ganged ink jets print out responsive to the data supplied from the repertoire storage medium. A number of housekeeping functions are carried out simultaneously, to insure that ink is delivered to and collected from the nozzles of the printing heads.

Abstract: Recording media comprising a mixture of 4,4'-bis(3-diazo-3,4-dihydro-4-oxo-1-naphthalenesulfonyloxy)benzil and an alkali soluble resin are suitable for recording information with electron beams. These recording media have high sensitivity, high resolving power and can be reproducibly formulated.

Abstract: A facsimile transceiver comprising a document/copy receiving drum, a motor for rotation of the drum about the drum axis and a read/write head mounted for linear movement in a direction parallel with the drum axis. When the transceiver is operating in the receive mode, the copy medium having adhesive along at least one edge circumscribes the drum in a closed loop so as to eliminate the necessity for transmitter-receiver angular synchronizing signals which would otherwise be required for locating the copy margin adjacent the edge of the copy paper. After completion of a transmission, the copy medium is severed along a line so as to provide an appropriate margin for the copied information content. The closed loop is formed from a single sheet having adhesive along at least one edge for purposes of forming a bond between opposite edges of the sheet when the sheet is applied to the drum.

Abstract: A time accounting system including at least three distinct elements: a magnetic stripped card, a recording clock and a recorder/encoder assembly. The magnetic stripped card is fed into the recording clock which prints and electromagnetically encodes predetermined information such as the date and time upon the card. The card is then output from the recording clock. At the end of a given accounting period, the cards are gathered and stacked in the input portion of the recorder/encoder assembly. The recorder/encoder assembly accepts each card and transfers the information contained onto magnetic tape for direct input to a computer. As each used card is read, the recorder/encoder prints and encodes a new card.

Abstract: An electrocardiogram (EKG) data strip is constructed with contiguous, repetitive segments to allow individual heart lead tracings recorded on the segments to be readily removed from the EKG data strip after the tracings have been completed so that the segments can then be inserted directly into a permanent record form.The EKG data strip of the present invention has a first longitudinal line of perforations along one edge, a second longitudinal line of perforations adjacent the other edge and a plurality of transverse lines of perforations extending across the EKG data strip between the first and second longitudinal lines of perforations. The transverse lines of perforations are located at spaced intervals along the length of the EKG strip to thereby divide the central part of the strip into a plurality of longitudinally aligned segments, each of which has a predetermined width between the longitudinal perforations and a predetermined length between two adjacent transverse perforations.
