Abstract: 1,013,848. Digital interpolators. SENTRALINSTITUTT FOR INDUSTRIELL FORSKNING. Aug. 31, 1962 [Aug. 31, 1961], No. 33555/62. Heading G4A. [Also in Division G3] In a digital interpolator for use in a machine tool control system, the controlled point moves on a curve whose gradient at any point depends on the ratio of two curve parameters, one parameter being added and the other subtracted in a common arithmetic unit, an addition being followed by an elementary step in one coordinate direction and a subtraction by an elementary step in the other co-ordinate direction, additions and subtractions taking place according as the content of the arithmetic unit is negative or positive respectively. If the parameters are kept constant, a straight line is generated, but if they are varied other curves such as circles or parabolas will be produced. All the curves generated are solutions of equations of the form where m, n, p, q are 0, + 1 or- 1. Numbers representing the initial values of the two curve parameters are fed from punched tape to the X-register and Y-register shown in Fig. 2. The contents of the X-register is subtracted from or the contents of Y-register is added to, the contents of an accumulator ACC according as accumulator content is positive or negative, as determined by a " carry " flpi-flop Cad. The addition or subtraction (by complementary addition) takes place in a serial adder AD. If a subtraction takes place an X-servo moves one step and if an addition takes place, a Y-servo moves one step. The contents of the X and Y registers may be modified at each step in addersubtractors ASX, ASY if it is desired to generate a circle or a parabola, the control signals for the modification being derived from the punched tape. The modification may be positive or negative depending on the quadrant concerned, a change of quadrant being detected by " zero test " circuits ZX, ZY. The attainment of the end point of the curve is detected when #X and #Y register, which originally contained numbers representing co-ordinate differences between the end point and starting point, reach zero.

Filed: 1970-07-10
Abstract: 1323432 Control of printers CANON KK 10 July 1970 [12 July 1969] 33684/70 Heading G4H [Also in Division B6]  In an electrographic printer where a whole line of characters is built up by several scans of an electrode across a recording medium, the movement of the electrode generates, photoelectrically or magnetically, trains of pulses which indicate the displacement of the electrode across and down the recording medium. As shown in Fig. 2 a character, the numeral "2" is synthesized from seven horizontal scans 01 to 07 during each of which the electrode is selectively energized in one or more of the time periods t 0 -t 1 ...t 4 -t 5  to create marks such as 118, 119. Four electrodes are carried on a rotating disc 13 each one making one of the scan lines across the recording medium 21 which is moved in steps. An apertured disc 14 carried on the rotating shaft 11 carrying the disc 13 generates by apertures 30 and photo-cell 34 one pulse for each of the 18 character positions across the recording medium and by apertures 31 and photo-cell 35 one pulse for each scan line. The pulses are fed to a control unit 39 which also receives from a computer 40 numerical data to be printed. Within the control unit a counter generates for each character pulse signals defining the time periods t 0  to t 5  (Fig. 10), plus t 6  for a decimal point position not shown in Fig. 10, and from which a logic arrangement of gates (Fig. 5, not shown) generates timing signals corresponding to all the possible lengths of marks, such as those of Fig. 10, that could be used to synthesize a character. According to the character to be printed and the line of scan (Fig. 7, not shown) particular ones of these timing signals are selected (Fig. 8, not shown) and fed to the electrodes. The character information for a line has to be presented successively for each of the seven lines of scan of a single line of print.

Abstract: 1,263,045. Transducing systems; local circuits. INTERNATIONAL BUSINESS MACHINES CORP. 13 July, 1970 [18 Aug., 1969], No. 33853/70. Heading G5R. A transducing system having at least three transducers across each data track and a guide track has an electrical circuit to select as the system output those transducers which are centred over their respective data tracks. As shown, each track is the width of three transducers. Supposing transducers 1 and 2 are on the guide track, then rectifiers 31, 32 will provide zero output and Schmitt triggers 41, 42 will be at "0" output. Transducers 3-5 will be on track A, reading data, and will set triggers 43-45 to "1" output. AND-gate 52 will be enabled since both its inputs are up and will thus enable AND-gates 62, 72 and 82 to feed the signals from transducers 4, 7 and 10, which are centred on tracks A, B and C, to OR-gates 65, 75 and 85. Where there are more than three transducers per track the centre transducer outputs are paralleled (Fig. 5, not shown). Instead of rectifiers, phase- or frequency-detectors may compare the data with a reference signal recorded in the guide track. The transducers may be photodiodes in magneto-optic systems (Fig. 3, not shown).
