Filed: 1966-11-21
Abstract: 1,159,841. Printing apparatus. MOTOROLA Inc. 21 Nov., 1966, No. 51966/66. Heading G4H. Printing apparatus of the type in which each character is formed from a plurality of dots includes flat piezoelectric bender bimorphtype crystals for activating selective ones of a row of styli to print the dots in the first row of the first character followed by sequential actuation of groups of styli to print the first row of dots for all the succeeding characters in the row before the sheet material is moved so that the following row of dots may be printed. This process is continued until a line of characters has been completed. In the embodiment described in which the data may be transmitted from a remote point to for example a mobile teleprinter the input pulses on lead 60 (Fig. 4) are read in to a five-bit shift register 61, a pulse being applied on terminal 63 after five bits have been received so that the contents of the register 61 are transferred into a further shift register 65, the output from which controls column select drivers 66-70 connected to a diode pulse matrix 72. The signals on lead 63 are also applied to a counter 76 which sequentially enables character select drivers 80 (there being one driver for each character in a line) to enable sequentially columns of transformers (Fig. 6, not shown) so that in accordance with the outputs from drivers 66-70 signals are applied to crystals 31-35 &c. to cause the crystal to flex and move a stylus connected to the crystal away from the paper. When the pulse is terminated the crystal is returned so that the associated stylus strikes the sheet material which is preferably pressure-sensitive having ink or dye in small cells in the paper, the cells being ruptured under the pressure of the stylus. When the top row of dots for all the characters in a line has been printed a sub-line feed escapement 89 is enabled by a pulse on terminal 84 to rotate the paper a small amount by energizing a solenoid. When a line of characters has been completed a line feed escapement 86 is enabled by a pulse on terminal 82 to energize the solenoid several times so that the paper is advanced by a greater amount.

Abstract: 1404559 Digital wave-form generator INTERNATIONAL BUSINESS MACHINES CORP 15 Nov 1973 [29 Nov 1972] 52991/73 Heading H3H A digital waveform generator comprises a digital storage device which contains successive digitally coded samples of a waveform stored in sequence each in one of a set of locations identified by an arithmetical series of addresses; means for repeatedly incrementing an address by a selected increment number and means for adding a selected constant number to an address; a multiplier producing a digital product of the storage device output and a modulation signal and a digital to analogue converter to convert the muliplier output to an analogue signal. The increment number determines the frequency of the generated waveform and the constant number the phase. As shown (Fig. 2) the increment number is inserted into 101 and timing signals open gate 102 passing the increment number to the accumulator which contains the address. The address is passed via gate 107 to sotre 105 where the relevant digital sample is selected and passed to D/A converter 110, the resulting analogue signal is a sample of the desired waveform and is built up by successive samples. To change the phase of the waveform, a constant may be added at 108. The multiplier 120 (Fig. 6) is inserted between store 105 and DIA converter 110 and comprises a source 122 of digital signals which are multiplied by the digital signals from the store. Several waveforms may be generated simultaneously using time division multiplexing and separate increment and phase stores. The outputs may be on the same or different lines, the latter case requiring several multipliers. The modulating signal may be analogue and converted to digital before multiplication. With this system a generated carrier may be amplitude modulated, frequency modulated or phase modulated.
