Abstract: 1481815 Transistor amplifiers FERRANTI Ltd 31 Oct 1975 [8 Nov 1974] 48363/74 Heading H3T An opto-electric coupler comprises a light source 10 and two photoconductive devices 12, 14 exposed thereto, one of the latter, 12, being in an output circuit 20, the other, 14, being in an input circuit 36 together with the source 10, whereby the source is driven so as to lineauze the relation between input and output signals. The light source 10 may be a gallium arsenidephosphide LED, and the photoconductive devices 12, 14 may each be a phototransistor Darlington pair. The input circuit may comprise a differential amplifier 40 having input terminal 46 earthed, the other input terminal 38 being maintained as virtual earth by negative feedback via the opto-electrical coupling 10-14. Thus the current through 14 is held equal to the input current at terminal 56. If 12 matches 14 and the optical paths 34, 58 are similar, and if the resistors 32, 50 are equal the output from amplifier 18 will equal the input voltage, and will follow variations over a range typically 0-10 volts. The circuit functions as described so far with positive input voltages, but for a bipolar input, resistor 59 may be added to bias diode 10 to a middle part of its characteristic, a corresponding resistor 60 being added to the output circuit. For handling only negative input voltages a modified circuit (not shown) without 59 and 60, may have the transistor 52 replaced by an NPN transistor, and the diode 10 and the pair 14 oppositely poled, with corresponding changes in the output circuit. In a thin film embodiment, Fig. 2 (not shown), four linkages (A, B, C, and D) off the structure may be either open or closed, different arrangements providing for (a) unipolar or bipolar operation, (b) differing input amplitudes or (c) differing input impedances.

Patent GB-493010-A (GB)
Abstract: 493,010. Secret transmission. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 25, 1937, No. 23303. Convention date, Sept. 14, 1936. [Class 40 (iv)] [Also in Group XL] An electron-discharge device of the cathoderay tube type is provided with a target electrode structure including a plurality of electrically independent electrodes arranged about a central point, at least one of these electrodes having at least one heart-shaped boundary edge. The device is particularly adapted for transmitting audio and other frequencies in the form of modulated or timed pulses, in which the transmitted wave has the form shown in Fig. 4 and referred to as a " constant frequency variable dot " (CFVD) modulated voltage wave or as shown in Fig. 7 and referred to as a " modified CFVD " (timed impulse) wave. The electron beam falls on a target 10 which may consist of two curved plates 14, 16 spaced slightly apart from one another, the plate 14 having a heartshaped opening in which the heart-shaped plate 16 is fitted. The plates may be of mesh a collecting electrode being arranged behind them, or they may be in the form of wall coatings ; alternatively, the plate 14 may be without aperture and arranged behind the plate 16 which is heart-shaped, or the plate 16 may be apertured and the plate 14 arranged behind it for producing a CFVD wave, or the front electrode may be a frame-like heart-shaped member with or without an inner heart-shaped member spaced therefrom for producing a modified CFVD wave. In the absence of any deflection of the beam, it strikes the point O, but on deflection the beam is caused to trace out a circular path, the diameter of which is at any instant proportional to the instantaneous value of the signal applied to the tube-deflecting plates. An impedance ZA, Fig. 5, is connected across the plates 14, 16, and according to the construction of the plates, signals are obtained, which have the form shown in Figs. 4 and 7. The beam is circularly deflected by means of a phase-splitting network comprising a resistance 60 and an adjustable capacity 47 connected in series across the supply voltage and the voltages are modulated in amplitude by sound, television, &c. signals to be transmitted. The system may be used to convert sine-wave voltages into flat-topped waves of equal frequency, the duration of the impulses being varied as-desired, and as shown in Fig. 5, the output of the oscillator 40, which is modulated by voltages from the source MP, is applied through the phasesplitting network through potentiometers to the tube-deflecting plates, so generating in the impedance ZA an output of the wave form shown in Fig. 4, which may be utilized to modulate a high-frequency oscillator 78. By providing a further anode 90 adjacent the target 10 which may also be a wall coating, secondary electrons from the target 10 may be collected. The modulated wave form shown in Fig. 7 may be used to " key " a radiofrequency amplifier. Electromagnetic deflection may be utilized and the modulation signal may be supplied to the anode instead of to the deflecting plates.

Abstract: 1,128,223. Data-processing apparatus; data storage. WESTERN ELECTRIC CO. Inc. 25 Nov., 1965 [14 Dec., 1964], No. 50131/65. Headings G4A and G4C. Data processing apparatus includes means for indirectly addressing a memory to extract signals representing a plurality of characters, means for shifting the extracted signals until those representing a desired character occupy a preassignÙd set of positions in a shift register, and means for masking the remainder of the shifted signals. In operation a specific instruction can call forth a subprogram to operate the extraction, the beginning location of the particular string of characters containing the desired character being specified and the location of the desired character being specified. This can be converted to identify the first bit of the character. The first instruction then extracts the contents of a specific memory location, the said contents then specifying the address of the required character, the subroutine then extracting the characters in this address, e.g. there may be 6 six bit words in a thirty-six bit address, and shifting the words until the required character occupies the least significant position of the shift register. The contents are then passed through a mask such that only the desired character is obtained for further processing.

Abstract: 1380041 Digital displacement measurement J H WESTLAKE J W SNYDER C H LEACH and S E CEBULIAK 20 Jan 1972 [22 Oct 1970] 50271/70 Heading G4H To measure the rate of penetration of a borehole drilling head a rotatable digital transducer driven directly by the cable lowering the drilling head, or by the pulley wheel over which the cable runs, provides binary coded words indicative of the direction and angular displacement, from which a rate of penetration signal is derived for recording against the penetration, the count of binary coded words ceasing if they are not presented in a repetitive, selected sequence. In the arrangement disclosed the digital transducer comprising a disc position encoder having two 1-60 6-bit binary opaque/transparent scales in succession gives 120 position signals per revolution or per foot of penetration. The 6-bit parallel output is fed to a comparator 21 whose other input is from a 6-bit counter 18, which on start-up is clocked on till comparison with the position encoder is achieved, whereupon a 1 is added to the counter. Thereafter a 1 is added to the count each time the transducer advances and equals the counter reading. The ones applied to the counter are also fed to a three-decade BCD counter 23 and every thirty seconds the contents of this counter are transferred to buffer register 24 and the counter cleared by means of a signal derived from clock 17 and divider 25. The contents of this buffer register thereby indicate the rate of penetration in feet per hour which is also the actual penetration in 1/10th of an inch made in the last thirtysecond period, the reading being displayed and also converted to an analogue signal for recording on a penrecorder whose chart is advanced by the ones added to counter 18. The scale of the recorder is adjustable. If the transducer signals are not in the correct sequence, due to temporary reverse motion of the drill, shut-down circuit 19 prevents counting of the coded words, until the last counted binary word is again presented in correct, forward sequence.
