Title: Electrical delay circuits
Inventor: GIBBONS PAUL
IPC: H04J3/04
Filed: 1952-09-29
Abstract: 719,354. Thermionic distributers. MINISTER OF SUPPLY. Sept. 28, 1953 [Sept. 29, 1952], No. 24388/52. Class 40 (3). [Also in Group XL(c)] Fig. 1 shows a receiver in a time-division 12 channel multiplexed communication system in which the multiplexed received signal at terminal t3 is distributed cyclically to the channels 1-12 each channel occupying a period 12 microseconds long. Triggering pulses at 72 microseconds intervals, Fig. 2(b) are applied at terminal t1 to the trigger-pair comprising valves VI, V2 to produce waveforms at their anodes as shown in Figs. 2(c), 2(d). A further voltage having a waveform as shown in Fig. 2(a) and synchronized at its leading edge with the triggering pulses is applied at terminal t2 and is added to the voltages at the anodes of valves V1, V2 to produce waveforms at points X and Y as shown in Fig. 2(e) and (f) respectively. These voltages are applied via a push-pull amplifier comprising valves V3, V4 to the input of a tapped delay line D which is terminated in its characteristic impedance at its distant end. Valves V3 and V4 are biased so that each valve only conducts during the most positive portion of the applied waveforms (Figs. 2(e) and (f) so that the input to delay line D consists of alternate positive and negative pulses of 18 .microsecond duration at intervals of 72 microseconds, as shown in Fig. 2(g). The line is tapped at six points as shown and the delay between adjacent tapping points is of 12 microseconds duration ; each tapping point is associated with a pair of gating circuits so that, for example, the first point applies a negative pulse to open the diode gate D1 to let through the channel 1 information from the multiplexed input on lead t3 to the integrating capacitor C10 and via the amplifier V6 and low-pass filter F1 to the terminals t4, t5 of channel 1. Tapping one also piovides a positive pulse 72 microseconds later to open gate D7 and let through channel 7. Similarly channels 2, 8 ; 3, 9 &c. are controlled by the succeeding tapping points. In a modification the delay line D is shorted at its distant end and only pulses of one polarity are applied to its input so that as the pulse travels down the line channels 1-6 are gated open and after reflection and reversal of its polarity channels 7-12 are opened.

Abstract: 945,686. Reading paper tape. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 13,1960 [July 13, 1959], No. 24437/60. Heading G4M. Means are provided for storing a single character inadvertently read from paper tape due to overshooting the read station after a stop order The machine is assumed to be such that only one character does so overshoot. If the tape has feed holes, under normal reading conditions switches 10a, 10b are set as shown in the Figure, the holes are sensed by photo-electric means 11a to 11h which conditions and gates 14a to 14h, and the sensing of the feedhole sets trigger 21. When the feedhole is past the sensing means 17, line 24 conditions and gate 25 to set a trigger 27 starting a clock 29 which opens the read-in gates 14 causing triggers 12a to 12h appropriate to the sensed holes to be set, opens the read-out gates 30 to pass the character for interpretation, resets the triggers 12 and the triggers 21, 27. On receipt of a stop signal and gate 25 is deconditioned and should a character then pass the read station and circuit 38 is conditioned by the feedhole to open the read-in gates 14, allowing the character to be registered. If the tape has no feedholes or pinhole feedhole switches 10a, 10b are set to the other position. Switch 10b holds the read-in gates permanently open and the sensing means thus act directly on the register 12. Hole sensing operates trigger 21 and when the character is past line 24 rises to condition and circuit 25. If the Go signal is not present, due to the setting of switch 10b any overshoot character is read into the register 12. If machine tolerances are good the read-in gates and clock may be omitted and the read-out gates opened by and circuit 25.

IPC: G06F7/498
Filed: 1961-07-07
Abstract: 971, 545. Electronic decimal multiplying apparatus. BUCHUNGSMASCHINENWERK KARLMARX-STADT VEB. July 7, 1961, No. 24655/61. Heading G4A. A keyboard decimal multiplier in which in each of a number of cycles digits of the numbers to be multiplied are paired so that the sum of their orders is the same, the sum of the products of the pairs of digits being accumulated to give a partial product, two stepping switches are used to select the digits, one being stepped up and the other down in each cycle, the intitial setting of the second counter in each cycle being one greater than the final setting of the other in the previous cycle. As shown the ten-digit numbers to be multiplied are set up by keys as connexions between horizontal lines (representing decimal denominations) 331-340 and 361-370 and vertical lines (representing decimal digits) 350-359 and 380-389. Stepping switches S4 and S3 comprising chains of flip-flops select the horizontal lines; initially lines 331,361 (representing the lowest denominations) are selected by the switching of flip-flop 241 by pulse generator 240 after a start pulse on 325. This switches 121. and 161; in the figure where the calculation 215 x 623 is shown as entered this will cause gates 25 and 73 to be enabled. Also monostable flip-flop 228 is actuated to switch flip-flop 63 and 15 And gate 227 is now enabled over lines 51 and 114 to open gate 233 by flip-flop 231;this enters pulses from 240 to be counted into the product store Z1-Z3 (Z1 being the lowest order). The pulses also pass through diode 53 to count down the digit 5 entered into S1 until 11 is switched to pass a pulse to line 56. This counts down by one the number in S2, and a pulse on lines 117 and then 50 switches on 15 again through gate 25. Again five pulses are entered into Z1 and S2 counted down one,until after 15 pulses 11 switches 61 in S2 so that via line 112 121 is switched off, to close 233 and open 234, and switch flip-flop 20 to prepare for a shift of the partial product. Pulses from 240 now count up Z1 until a carry pulse switches flip-flop 279 to close gate 253 and open 252 and thus pass the remainder of the ten pulses (until 11 is switched to switch check 279 and close 252) to Z0 which now contains the least significant digit of the product for transfer out to a product store (not shown). The use of S1 to gate ten pulses to shift the contents of the partial product register continues, with the contents of Z2 and Z3 being transferred to Z1 and Z2 respectively. 232 is now switched to register the number 2 in 33 (since 161 enables gate 181) and the second digit (1) of the multiplicand is multiplied by the first (3) of the multiplier as above described, and next the first digit of the multiplicand and the second of the multiplier, when 121 is switched off to repeat the shift, obtaining the second result digit. The process is repeated, the final count in S4 in each cycle controlling the initial count (one greater) in S3 by means of diodes 181-198.

Title: Improvements in or relating to processing photographic layers
IPC: G03D5/04
Filed: 1954-08-25
Abstract: 752,048. Processing photographic layers. KODAK, Ltd. Aug. 25, 1954 [Aug. 26, 1953], No. 24740/54. Drawings to Specification. Class 98 (2). A foam, described as a dispersion of gas bubbles in a liquid, and preferably one in which the liquid is of 2-30 per cent of the total volume, is used for the processing. Water with a foam producing agent may be used, as when other processing material is present in the layer, or the foam may contain developing agents as for silver halide, diazotype or iron salt systems of photography, or may contain stabilizing agents such as acid or thiourea, or bleaching, dyeing or toning agents, or fixing agents such as hypo. The foams may have a stability of one second or less, resulting as from the presence of acetic acid in a stop bath or from the addition of a lower alkyl alcohol to an aqueous developer; or a stability of hours or days as by use of cationic or anionic detergents for low and high pH materials respectively. The foam may be prepared just before use or may be supplied from a self-contained unit of the type used for dispensing whipped cream or shaving lather. A short life foam may be spread over the layer to break down to a liquid in three seconds or less and effect processing, or a more stable foam may be broken down as with blotting paper or defoaming agents. Squeegees or rollers may be used to control, spread, or finally, remove the foam or liquid produced therefrom. Baffles to prevent splatter of foam and traps to collect excess liquid may be present during use of the foam, and instances of use described are for quick development as for document copying, aerial reconnaissance or television, processing of an outer layer only of a multilayer colour film or one side at a time of duplex coated film, and particularly for the silver-salt transfer process. In Example 1 foam is made by supplying compressed air through the stem of a funnel of Buchner type containing a developer which includes sodium lauryl sulphonate, and a thin coated gelatino-silver chloride paper which has been exposed to a line image is drawn over the top of the funnel to receive the foam. After 5 seconds for development excess is removed with a squeegee and the paper is foamed similarly from a solution containing thiourea, acetic acid and saponin, squeegeed after 10 seconds, and printed using a Photoflood lamp. Example 2 describes the production and use of pressurised foam producing containers for similar developing and stabilizing solutions; and Example 3 foam processing in roller-contact solvent transfer, using a gelatino-silver bromoiodide emulsion, continuous tone exposure, and a receiving sheet of baryta paper treated with an aqueous mixture prepared from silica, sodium sulphide, cadmium acetate and lead acetate. Specification 745,445 is referred to.
