Title: Improvements in or relating to electrical calculating circuits
IPC: H03K21/00
Filed: 1957-06-21
Abstract: 847,121. Coin-freed systems. GENERAL ELECTRIC CO. Ltd. Aug. 20, 1958 [June 21, 1957], No. 19637/57. Class 40 (4). [Also in Group XIX] A multiplex adding and subtracting arrangement particularly adapted for use in pre-payment telephone call timing consists of a number of binary counting stages (of which the first, least significant, three are shown in Fig. 1) each comprising a number of " and " gates (5, 21), " or " gates (15, 24) and." inhibit " gates (8, 18) and a delay line 12 (which may be magnetostrictive, mechanical such as of mercury or quartz, or a magnetic drum) providing a delay of 100 bit periods so that 100 accumulated totals may be stored in the lines 12, 13, 14, ... where they circulate unchanged through gates 15, 18; 16, 19, . . . in the absence of pulse inputs at 1, 2 or 11. Considering one of these totals, it will be increased by one by a pulse received at 1 at the appropriate time (as the bits of the stored number are simultaneously leaving the delay lines) since if no pulse (representing a 0) is leaving 12, gate 5 will be closed and gate 18 open so that a pulse (representing a 1) is entered in 12 through 15 and 18, and if a pulse is leaving 12, gate 5 is opened to close gate 18 through 24 and register a 0, and pass the input pulse to the next highest stage. The total will be decreased by 1 by an input pulse at 2 by similar action of gates 8, 21, 9, 22, &c. Lines 27, 28, 29, . . . allow read-out, and a pulse on line 11 acts through gates 24, 25, 26, ... to re-set the total to zero by closing gates 18, 19, 20, .... Fig. 2 shows the application of the Fig. 1 counter to a telephone call timer for use in an automatic telephone exchange. A signal generator (such as that described in Specification 824,352) provides output pulses for any one (or more) of the 100 channels of the multiplex counter of Fig. 1, the rate of production of such pulses for the channel being determined by the distance of the telephone call (as determined by the routing digits dialled) to which the channel is allocated. Coins inserted by the caller supply a number of pulses corresponding to their value to terminal 1, and signal generator pulses applied to 2 successively reduce the number registered until it reaches zero, and then 1 1 1 1 . . ., which when read out on output lines 27, 28, 29,... acts through " and " gate 30 to store a " 1 " in the appropriate channel position of delay line 33, (forming part of a recirculating store) which when received on line 37 disables through inhibit gate 34 the signal generator for that channel and provides a signal for the caller that more coins must be inserted; if they are the " 1 " stored in 33 will be erased by inhibit gate 32 and the signal generator will thus again operate on the channel, the signal will be discontinued, and the Fig. 1 counter will count down the further payment as before. Specification 816,487 also is referred to.

Title: Automatic slit control for spectrophotometers
IPC: G01J3/04
Filed: 1961-06-02
Abstract: 921,646. Spectrophotometers. BECKMAN INSTRUMENTS Inc. June 2, 1961 [Nov. 21, 1960 (2)], No. 19905/61. Class 40 (3). In a spectrophotometer in which radiation passes alternately along sample and reference paths, the combined beam is chopped at a frequency and/or phase different from the alternation. As a result, the detector output contains two signals one of which is to balance the beams, the other being combined with a signal indicative of the setting of a balancing attenuator to give a third signal controlling the exit slit of the monochromator. Rotating mirrors 14, 15 direct radiation from a source 10 along sample and reference beams 18, 19 in turn. The combined beam is chopped at twice the frequency by chopper 25 and falls on a thermocouple 13 by way of a monochromator 12. A demodulator 33 attuned to the rotation of mirrors 14, 15 detects out-of-balance between beams 18, 19 and operates a servomotor 24 to adjust a balancing attenuator comb 23. A demodulator 34 attuned to the rotation of chopper 25 produces a signal indicative of the mean intensity of radiation in the two beams. This signal and a signal indicativeof the comb position are fed to a modulator 42, the output of which varies with unwanted variation in radiation intensity and is used to control the width of the exit slit 27. A slit programme voltage may be connected to the servo amplifier 43 through a high impedance in mixer 46 so that the programme takes over the slit control if the sample transmittance falls below 3-5%. The demodulators 33 and 34 and the modulator 42 may comprise mechanically-oscillated switches. In modifications, the chopper 25 may be incorporated in one of mirrors 14, 15, Figs. 2 and 3 (not shown).
