    Abstract: Record conversion system, whose magnetic core register comprises a plurality of magnetic cores arranged in a matrix to represent data located in rows and columns having common core digit windings connecting the cores of each row, common digit input curls connecting the cores of each column, read-out coils of common core connecting the cores of each row, common core interpreter coils connecting the cores of each column, means for printing a half-stream on selected coils of said digit coils during each input operation, means for printing a half-stream on successive digit input windings during successive input operations whereby cores are magnetized at the intersection of such driven windings, characterized by means of printing a discharge pulse; core gauge on said read-out windings in successive order thereby generating an output pulse in the above interpreting windings on magnetized cores discharged by said read-out pulses.

    Abstract: 888,389. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 17, 1958 [Nov. 18, 1957], No. 36912/58. Class 100(4) Feed rollers and bands. Documents of varying size and thickness are fed to a printing position by a pair of feed rollers 24, Fig. 3, which move a document in one direction into the machine, where it operates contacts which make effective a pair of contiguous belts which feed the document in a different direction to the printing position, grippers hold the document during printing and a second pair of belts 145 carry the document to a stacker. The data to be entered on the document is determined by a keyboard 12, Fig. I, which is used for permanent data that is printed repeatedly, and an adding machine 11 of the TEN KEY TYPE which enters data in the printed circuits of a store. After the data is entered, the document is inserted in a slot 14 and the feed rollers 24 carry it to a position where buttons 96, Fig. 3, are raised closing contacts 97 both of which must be operated to actuate a drive for a link 86, Fig. 5. The drive link 86 moves to the right and pressure rollers 81 and the upper reach of the lower belt 67 are pressed upwards so that the document is gripped and fed by the belts 61 and 67. These, together with further separate belts 62, 68 are set at an inclined angle so that the document is moved against an aligning wall prior to reaching the printing position. The lower further belt 68 is also pressed up by action of the link 86, but at a small pressure, so that the document can be held in the printing position by a gate 110. After printing the document is fed away by a series of belts 144, 131, 147, and 154 into a delivery hopper 17. Type wheel machines; type wheels. The printing machine comprises type wheels 266, Fig. 22, and two code wheels 264, 265 mounted in a type carriage 260 slidable on rods 254, 256. The type wheels are positioned by a set up mechanism 193 comprising a series of pulleys which, by the combination of their movements, pulls a tape 310 a particular amount and a bell crank 313 is rocked. The bell-crank 313 carries a pulley 315 5 and a second pulley 316 is mounted in the right hand frame member 253. A tape 317 is carried from the type carriage frame 260 where it is secured over a pulley 315 around pulley 268, Fig. 22. Any movement of the tape 310 in either direction will rock bellcrank 313 thus lengthening or shortening the loop formed by the tape 317 which will rotate pulley 268 and thus position the type wheels. This action can take place with the carriage in any letter-space position as the tape 317 merely-feeds around the pulleys 315 and 316 as the carriage is moved laterally, without in any way effecting the type wheel, but a slight change in the dimensions of the loop 317 will alter the printing wheels in their position. Aligning for impression. The type wheels are aligned by a star-wheel 304, Figs. 4, 22 on the type wheel shaft 267 and a pawl 303 which is raised and lowered by a linkage 302 from a cam 300 on the shaft 263. To adjust the relation between the wheel 304 and the pawl 303, the pawl pivot is adjustable. Letter-spacing. The type carriage 260 is letterspaced by a power-driven shaft 182, Fig. 12, from a one revolution print clutch 183 connected to an electric motor 26. An eccentric pin 197 on the end of the shaft 182 engages with the teeth 198 of the disc 200 in a Geneva action wherein the drive accelerates and decelerates evenly with a dwell between. A pin 201 carried on a holding port 202, Fig. 12, normally holds disc 200, but is displaced by a letter-spacing rotation of the pin 197. A safety pawl 209 engages a notch 210 formed in a black space on the periphery of the disc 20 if the print clutch fails. The pin can then rotate idly in the blank space adjacent the notch. Carriage driving-mechanism; margin stops. The carriage-return spring is wound up by the power letter-space action and returns the carriage to the printing position which may be in either of two fields on the document. A two notch stop plate 217, secured to the disc 200 co-operates with a pawl 215 to stop the disc. As shown in Fig. 12, pawl 215 is engaging in notch 218 but if an electromagnet 212 is operated the pawl 215 is lowered to engage a notch 220 thus permitting printing in the second field. Shock-absorbing stops. A dashpot 221 is coupled to the magnet 212 so that it effects cushioning at either printing position. Hammer impression arrangements. A simple lever printing hammer 270, Fig. 22 is provided for the type wheel 266 and a second print hammer 290 carried in an arm 274 is provided for the code type-wheels. Both hammer 270 and arm 274 press a magnetic ink ribbon paper and a plastic strip platen against the type and are secured for travel with the carriage 260. The hammer arm 274 is bail shaped and has an end 282 which engages an adjustable anvil 283, and which varies the spread of the ink on the document. The hammers are driven by springs 291 which press arm 277 to engage lugs 276 which act as cam follower to cams 280 secured to a sleeve 272 surrounding a cam-shaft 263. The cam-shaft 263 has two parallel recesses 273 engaged by rollers 271 carried in the sleeve 272 so that the sleeve may move laterally but rotative therewith to effect printing operations. The hammers are controlled by latches 277 released by relay operated mechanism. Platens. The hammers press the paper and ink ribbon against the type through a plastic platen.
