Title: Data handling system
IPC: H03M7/30
Filed: 1972-12-28
Abstract: 1396900 Digital transmission; coding; facsimile system INTERNATIONAL BUSINESS MACHINES CORP 28 Dec 1972 [5 Jan 1972] 59808/72 Headings H4P and H4F Each digit count in a facsimile run length coder is first split into component numbers whose sum equals the said count, and then the lowest magnitude number is converted into a first code, and all the higher magnitudes are severally converted into a second code. The run length coder first predicts what each scanned bit is likely to be, and the coded and transmitted count is then the run-length between prediction errors. The coding system.-Each total count N is split up according to the formula wherein p, n are preferably 10 and 6 respectively, to give compatibility with the hexadecimal numbering of many computers. The lowest magnitude component number is then one of the range 0 to 9 inclusive (ten numbers), and the ascending magnitudes are respectively in the ranges 00-10-20-30-40-50 (six numbars), 000-60-120-180-240-300 (six numbers) and so on. Any total count N can be constructed by selecting an appropriate single number from each range and adding these together. The codes for the lowest magnitude numbers (0 to 9) are, respectively, their corresponding binary numbers (0000 to 1001). The codes for the six numbers in each of the other ranges are the binary numbers corresponding to 10 to 15 (i.e. 1010 to 1111). Other codes, and other p, n values are described. The run-length coding system (Fig. 2).-A line buffer 53 stores the bits for a single line scan of a document and each input bit from 51 is also fed via 75 to be compared with a predicted value for the bit (black or white) from 73. The prediction is derived from the preceding bit D and three bits ABC from the preceding line by a logic circuit 61A-61D, 63 (also Fig. 3a, not shown) whose logic functions are chosen, according to the general type of document being scanned. Correct predictions produce outputs on line 77b and it is these correct predictions which go to counters 78, 79 to be coded according to the above scheme. A wrong prediction gives an output at 77a which through 155, 153 causes clock B to drive a counter 120. This successively generates the addresses of gates 81B, 80B, 79B, 78B which pass the accumulated coded count to a compressed buffer memory 140. The counters then reset ready for another count of correct predictions. Each read-out of an accumulated coded count thus implies one wrong prediction, and an immediately following second wrong prediction is indicated by a 0 sent to the memory 140. The decoding system (Fig. 4, not shown) recognizes the codes stored in the compressed buffer memory 140, by means of registers 280A -280D, 281-284 controlled by a clock A. Then a clock B "counts down" the number corresponding to the recognized code and simultaneously causes bits to be fed to a register 302. This seeks to reconstruct the original (scanned) data using similar prediction logic 270, the prediction being corrected at 207, 208 each time a count is completed (the count representing the run lengths between prediction errors in Fig. 2).

Patent GB-723865-A (GB)
Abstract: 723,865. Calculating-apparatus. OLYMPIA WERKE WEST GES., [formerly ORBIS BUROMASCHINENWERKE GES.]. Dec. 7, 1950 [Dec. 7, 1949], No. 30042/50. Class 106 (1). An add/subtract totalizer is automatically positioned for taking true negative totals by means of a control member moved longitudinally by the lowest denomination totalizer rack, whenever a fugitive one is added, and rotationally adjusted according to the totalizer position. The control member is shown, Fig. 1, as a bar 1 pivotally supported by a bracket 2 which is rocked to lift the bar whenever the totalizer rack 20 is lifted to enter the fugitive one. If the totalizer 10 is then in its " add " position, a pin 9 thereon holds the bar against a spring 7 so that an ear 16 on the bar rocks a control lever 21 clockwise. If, however, the totalizer is positioned for subtraction, its pin 9 releases the bar 1 which is rocked counterclockwise by the spring 7 and so rocks the control lever 21 counterclockwise by means of a second ear 17. The lever 21 is thus always in the position corresponding to the mode of engagement of the totalizer when it last passed through zero, and therefore, registers the negative or positive condition of the totalizer. Machine functions are selected by toothed slides 35, 36 and 37, Fig. 2, differentially settable by control keys in the manner described in Specification 723,864. The slides 36 and 37 are only moved for totaltaking and carry with them the slide 35 and an arm 33 of a lever 28. If the control lever 21 registers a negative totalizer condition it obstructs full movement of the lever 28 and the slides are stopped short of their normal movement. A tooth-space in the slide 35 then registers with a feeler lever 39 which is thereupon moved by its spring 45 to swing a pitman 41 counterclockwise about its pivotal mounting 50 on an actuator lever 40. The pitman 41 is lifted by lever 40 early in the machine cycle and a shoulder 54 on it rocks a lever 62 clockwise, the lever 62, through a link 65 and the pin 9, swinging the totalizer into its subtract position. If the lever 21 registers a positive total it clears the lever 28 and the slides are permitted their full movement; the feeler lever 39 is retained in its upper position shown by a tooth 47 of slide 35 and the pitman is positioned by its spring 61 for rocking the lever 62 counterclockwise to swing the totalizer into its add position.
