Title: Character recognition apparatus for bar coded characters
IPC: G06V30/224
Filed: 1973-12-12
Abstract: 1434377 Bar coded data reader INTERNATIONAL BUSINESS MACHINES CORP 12 Dec 1973 [20 Dec 1972] 57520/73 Heading G4M A reader for bar coded data has a magnetic read head 3 supplying signals via amplifiers 5, 7, 9 to a differentiating circuit 15 and difference amplifiers 11, 13, 17, 19. Data signals 5 are fed to amplifiers 11, 13 and the differentiated signals are fed to amplifiers 17, 18. Amplifier 11 receives a reference voltage Va and supplies a signal LPP indicating a large positive peak and amplifier 13 receives a reference voltage Vb and supplies a signal PP indicating a positive peak (Fig. 4). Amplifier 17 is fed from a switchable voltage reference unit 21 which supplies a lower reference voltage initially until after the peak of the first positive going portion of the differentiated waveform and is then increased to a large reference value by a signal at terminal 21. Amplifier 19 is fed from unit 16 supplying three reference signals, initially a high value and is lowered for each of the positive going portions of the differentiated waveform and is raised to an intermediate level for each of the negative going portions of the differentiated waveform. A circuit controlling the reference units 14, 16 and decoding the signals produced is described (Figs. 2, 3, not shown). The first NS pulse from amplifier 19 enables an oscillator so that a count representing pulse width can be obtained and for a first bit (a start bit) a width above 16 microseconds causes a " 1 " to be stored in a shift register and for succeeding bits a count above 24 microseconds causes a " 1 " to be stored in the shift register and a count above 100 microseconds causes a " 0 " to be stored. When the shift register is full its data is decoded to determine the character that has been read. Two counters can read the time between successive leading edges and trailing edges respectively for error detection. The signal PP is used to set reference unit 16 to its highest value. Reference unit 14 is controlled by the LNS signal from amplifier 17. The signal on input 27 to reference unit 16 is controlled by the LPP and the PP signals.

Title: A thin-film EL image display panel
IPC: H04N3/14
Filed: 1978-10-06
Abstract: A thin film electroluminescent panel, matrix driven to provide a half tone TV type display, holds amplitude modulated voltages on its electrodes corresponding to the voltage remaining on the panel capacitances after charging to a fixed voltage followed by charge leakage either at constant current for a period proportional to the sampled video signal or with amplitude modulated current for a fixed period. The samples of video signal are taken via gates AD and temporarily stored in capacitors Ch during one line scan period for display during the next. The line electrode Yj corresponding to the signal line just sampled receives zero voltage, while all others receive threshold voltage Vth of the same sign as the X electrodes to inhibit luminescence; the voltages left on each X electrode then appear on the cells opposite line electrode Yj superimposed on Vth applied to the X electrodes via all capacitances other than those opposite Yj, allowing half tone luminescence along Yj. During the vertical retrace interval the whole panel is refreshed by a uniform reversed voltage applied to all Y electrodes. <IMAGE>

Title: A method for generating hydrofluoric acid in a subterranean formation
IPC: C09K8/72
Filed: 1978-11-09
Abstract: Hydrofluoric acid is generated or formed in a subterranean siliceous formation by a method wherein an injected aqueous solution of a fluoride salt and an injected aqueous acid solution is combined in the pore spaces of the formation. This is accomplished by immobilizing one of the aqueous solutions on the pore spaces of the formation by displacing the aqueous solution into the formation with a liquid that is substantially immiscible with the injected aqueous solution, thereby driving said aqueous solution to a saturation at or below its residual saturation. The other aqueous solution is then injected into the formation.
