Abstract: 1,014,495. Selective printing. SIEMAG FEINMECHANISCHE WERKE G.m.b.H. July 20, 1962 [Aug. 3, 1961], No. 27954/62. Heading B6F. Apparatus for printing a line of information contained in coded form in a magnetic storage, e.g. magnetic drum, tape or core matrix, and including a number of side-by-side settable type bars 1 which may be arcuate in shape, comprises a control member 3 for each type bar, which member is moved synchronously and simultaneously with the reading of the storage, and means for coupling and uncoupling the members 1, 3 so that for each item of the code as it is read the member 3 imparts to the type-bar 1 a movement corresponding to that item. As described, the information is stored in a magnetic core storage with four horizontal storage lines having the code values 1, 2, 4, 8 in that order, and as many vertical rows as there are type-bars 3. The code values correspond to the binary code for presenting one of ten type faces on a bar 3 adjacent to a platen 7, and reading of them causes the bar 1 to move from its rest position through 1, 2, 4, 8 units or combinations thereof up to 10. The member 3 has four vertically displaceable latches 6<SP>1</SP> . . . 6<SP>8</SP> spaced one, two and four units. An electromagnet 4 is situated below the latch 6<SP>1</SP> when the first code position is read, and when energized moves a latch 6<SP>1</SP> &c. situated above it into engagement with teeth on the type bar 1 to couple the members 1, 3 together. To the left of the magnet 4 and spaced therefrom one, two, four and eight units are electromagnets 5<SP>1</SP> . . . 5<SP>8</SP>, each of which if energized withdraws a projected corresponding latch 6<SP>1</SP> . . . 6<SP>8</SP> situated above it. If there is a code reading in the " one " position, the magnet 4 is energized, the latch 6<SP>1</SP> couples the bar 1 to the member 3 so as to move therewith. The magnet 5<SP>1</SP> is now energized either under control of the movement of the member 3 or by a signal read from the storage and withdraws the latch 6<SP>1</SP>, the bar 1 having moved forward one unit. Similarly if code readings occur in the 2, 4 or 8 positions, the magnet 4 operates the corresponding latch 6<SP>2</SP> . . . 6<SP>8</SP>, and the corresponding release magnet 5<SP>2</SP> ... 5<SP>8</SP> is energized so that the bar 1 receives movements of 2, 4 or 8 units. Movements of other magnitudes up to ten can be obtained by code readings at two or more positions. In this arrangement the type bars are set one after the other, and the release devices 5<SP>1</SP>, 5<SP>8</SP> may be common to all the bars. The type bars and their control members 3 may be divided into groups, Fig. 2, all the control members 3<SP>1</SP> ... 3<SP>4</SP> of a group being moved simultaneously. In this case the latches 6<SP>1</SP> . . . 6<SP>8</SP> on each member 3 are as shown in Fig. 1 but are displaced relatively to those on adjacent members and the reading of the storage for the various type bars is correspondingly timed. When all the bars 1 have been set, the selected type are moved relatively to the bars to strike the type simultaneously against the platen 7.
