Title: Apparatus for reading
IPC: G06V30/10
Filed: 1965-03-15
Abstract: 1,045,040. Automatic character reading. FARRINGTON ELECTRONICS Inc. March 15, 1965 [March 25, 1964], No. 10850/65. Heading G4R. In automatic reading apparatus the character is scanned in a vertical raster and black and white signals of each scan being compared with the black signal of the previous scan so that a stroke crossing several scans is followed from scan to scan. The image of the character is dissected by a slotted disc and signals produced by a photo-cell 543, Fig. 1 (not shown), are clipped. The video signals are delayed at 544 for example by being recorded on a magnetic drum and read again at another point. The delay is slightly less than one scan and the signals are stretched so as to overlap a similar signal in the next scan. In comparator 545 the delayed signal is gated with the video signal of the present scan and an output indicates that the same stroke or " stream " crosses both scans. The video signal is also applied to a stream counter 548 which counts the black strokes encountered in each scan. When new strokes are detected they are numbered and recorded in trigger matrix 549, along with old strokes, according to the sequence in which they appear. This information passes to a pattern control matrix 551 which controls the switch circuitry in stream switch unit 547 to route into appropriate channels the numbered streams as they re-appear in each successive scan. Signals from these circuits, which together form stream routing unit 546 pass to detector 522 producing at 553 and 555 signals indicating the presence of certain shape elements. These features are associated with the streams in which they occur and are designated as occurring in the upper or lower half of the character. The output signals are applied in appropriate combinations to And gates in recognition circuit 556 to obtain an indication of the character recognized. The elements extracted and used for recognition are as follows. A long vertical line which is detected by integrating the black signal in any scan. Two long vertical lines obtained in the same way. An upper split is indicated when a single stream detected in the upper half in one scan becomes two streams in the next. An upper join is indicated when two streams detected in the upper part of the character in one scan becomes a single stream in the next. A lower split and a lower join are as above, but occurring in streams in the lower half of the character. For the purpose of combining split and join signals with positive signals a circuit is provided which determines which of the four possible streams is the uppermost. The next feature is an upper horizontal. The presence of a horizontal is detected by measuring the height of a stream in successive scans. If a horizontal is detected in any stream this indication is combined/with an indication of whether or not that stream is uppermost. The last feature is a split after join which is obtained by combining a join signal with a split indication occurring any time afterwards.

Title: An amplifying voltmeter with a logarithmic scale
IPC: G01R15/00
Filed: 1948-04-20
Abstract: 636,727. Thermionic valve voltmeters. COMPAGNIE INDUSTRIELLE DES TELEPHONES. April 20, 1948, No. 10855. Convention date, May 13, 1947. [Class 37] A voltmeter with a logarithmic scale comprises an amplifier constituted of several partial amplifiers in series, a detector at the output of each partial amplifier, and at the output of each detector a direct current amplifier formed by a valve with a logarithmic characteristic. As shown diagrammatically in Fig. 1, alternating current amplifiers 10, 20, 30, 40, detectors 11, 21, 31, 41, direct-current amplifiers 12, 22, 32, 42, and limiters 23, 33, are connected in a circuit including an indicator G. The first amplifier 10 of the series has a gain of 20+Y decibels, while each of the other amplifiers 20, 30, 40 has a gain of 20 decibels. Each of the detectors 11, 21, 31, 41 comprises a diode 1, Fig. 2, the cathode 3 of which has a fixed bias V, e.g. +0.5 volts. Each of the D.C. amplifiers 12, 22, 32, 42 is constituted by a variable slope valve 5, the plate 7 of which is connected to the measuring instrument G. The cathode has a fixed bias Vo. Negative potential developed by the passage of the rectified current in a resistance 4 is transmitted through a filter network consisting of a resistance r and condenser C to the grid 6 of the valve 5. The anode current Ia of the valve 5 varies with the negative grid potential Vg as shown in Fig. 3a. The direct current of an amplifier such as 12 is a logarithmic function of the voltage V applied to it, as shown in Fig. 3b. The total current in the indicator G is the sum of the four partial currents I1, I2, I3, I4 in the amplifiers 12, 22, 32, 42 as shown in Fig. 3c. The limiters 23, 33 prevent the following amplifiers from being saturated when the previous amplifier is giving its maximum output voltage. As shown in Fig. 4, each limiter is constituted by a valve 1, of which the anode is supplied through an impedance z and the grid 2 is earthed through a high resistance R. The cathode 3 is given a fiXed bias VL. When the alternating voltage applied to the grid exceeds the peak value VL, the limiter transmits through the condenser C to the following amplifier, the limiter 23 to the amplifier 30; for instance, a fixed voltage having a peak value about VL. When the apparatus is used as an indicator and not as a recorder, precision may be increased by the circuit shown in Fig. 5. Ganged switches 1 ... 8 each with five positions a ... e are inserted between the detectors. 13 ... 16 and the D.C. amplifiers 9 ... 12. With the switches in position a, measurement is effected as previously described. With the switches in position d the grids of the valves 9 ... 12 are in parallel across the anode of the active detector 15 so that the total deflection is given for 20 decibels instead of 80.
