Title: Adaptive logic system
IPC: G06N3/063
Filed: 1965-12-01
Abstract: 1,066,280. Adaptive logic systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 1, 1965 [Dec. 24, 1964], No. 50901/65. Heading G4R. Adaptive logic units are arranged in series, the output of each unit except the last being connected to an input of the next unit, and training means for training any one of the units to produce an output signal which is any desired function of input signals applied in common to all the units is arranged to attempt to train each unit in turn until one is found which can be trained. Adaptive logic unit.-Each unit is an adaptive threshold unit (e.g. ATU1, Fig. 2b, not shown) similar to that described in Specification 1,066,279 which is referred to. Bit input signals are applied to first ends of the resistors of respective potentiometers and via inverters to the other ends. The potentiometer taps (70-1 to 70-n) are connected together to feed two seriesconnected operational amplifiers the last of which acts as a threshold device to provide the unit output and the other of which receives a reference voltage from a variable potentiometer (88). An increment or decrement signal (INC1, DEC1) applied to the unit alters in the appropriate sense, by means of stepping switches, the tap position on the " reference " potentiometer and those of the other potentiometers whose input bits are currently " one." Training.-A binary counter (CTR) provides the various possible input bit patterns to the adaptive logic units (excluding the bits from other units) in turn, a ring (TR) concurrently sampling corresponding switches (ON1 to ON8, OFF1 to OFF8) which specify whether the system output should be " one," " zero " or indifferent for each input pattern. The switch states are compared with the output bit of one of the units to produce an increment or decrement signal (INC, DEC) which is applied to that same unit. The unit involved is selected by a ring (SCCR) which initially selects the first unit. If no increment or decrement signal is produced during one complete run-through of the sequence of input bit patterns, i.e. one cycle of the switch-sampling ring (TR), an AND gate (185) produces an output which terminates the training. If this does not happen within a fixed number of the said run-throughs on a given unit, a counter (CCTR) produces a signal which advances the unit-selecting ring (SCCR) to select the next unit, and so on. The output of the unit on which this ring is fixed when training ends (see above) is selected by this ring to provide the system output (SFO) during subsequent use of the now-trained system.

Title: Automatic sight and tracker harmonisation
IPC: F41G7/30
Filed: 1969-11-04
Abstract: 1372348 Photo-electric guidance BRITISH AIRCRAFT CORP Ltd 4 Nov 1970 [4 Nov 1969] 54000/69 Heading H4D In a missile guidance system in which the operator moves a telescope to follow a target, and a light source associated with the missile is tracked by a tracker including a vidicon, collimation error between the telescope and tracker is corrected by performing an initial nulling operation which subsequently results in compensation of such error in use of the system. The tracker detects offset angle and offset distance of the missile from the line of sight to the target and transmits correcting signals. During performance of the nulling operation, light from a small source lamp 25 (Fig. 1) provides an image I on the screen 21 of the vidicon of the tracker 16. At the tracker output terminals 38, 39 (Fig. 2) voltages appear which are proportional to the co-ordinates of the displaced image relative to the electrical centre of the screen, the displacement being due to the collimation error. These voltages are supplied, via switches 42, 43, to integrator circuits 34, 35 where capacitors 32, 33 charge up to store the voltages. During capacitor charging, the outputs of the circuits 34, 35 are fed back, via loops 40, 41, to the terminals 38, 39 to reduce the inputs to the circuits 34, 35. When these inputs are reduced to zero, the nulling operation is complete and switches 42, 43 are opened. Since the charges stored on the capacitors 32, 33 are still applied to the terminals 38, 39 they result in reduction of any voltages appearing at these terminals from tracker 16 during following of a missile, thus compensating for any collimation error, between the tracker and telescope, in the missile following signals. As shown the tracker and telescope are mounted in a common container 1 supported in gimbals. During missile following, light from lamp 25 is prevented from reaching screen 21 by interposition of a small, opaque disc 47. The light of lamp 25 still enters the telescope to form a graticule. The light source associated with the missile may be its own exhaust and, possibly, an additional beacon.

Title: Apparatus for and a method of recording a time varying signal on  light sensitive material

Abstract: 1316520 Cathode-ray tube displays MEDICOR MUVEK 22 Nov 1971 [5 Dec 1970] 54086/71 Heading H4T The trace produced on the screen of a cathoderay display tube 12 (Figs. 1 and 4) by a (time) varying electric signal supplied to the vertical deflection plates 21 to deflection modulate a time-base trace supplied to the horizontal plates 22, is recorded on a strip of light-sensitive material, e.g. photographic film, 15, which moves across the screen at a uniform rate in the same direction as the movement of the beam spot 41 on the film. When an image has been recorded (i.e. at the end of one cycle of the time-base) the beam is blanked and the time-base arrested until a non-exposed part of the film is located opposite the screen, to prevent overlapping between successive recordings. Alternatively such overlapping may be prevented by adding a positive or negative shift voltage to the vertical deflection plates 21 to shift successive recordings by a distance "S" as shown in Fig. 5. The apparatus may be operated without a time-base deflection which is only brought into use, e.g. by operation of a push-button, when a phenomenon is observed (e.g. on the screen of a monitoring cathode-ray tube) which should be investigated in the greater detail in the expanded format which the time-base deflection provides. Fig. 6 shows an arrangement which allows the latter operation by means of switch 67 and push-button 68 which controls a trigger 66 for the time-base sawtooth generator 64. In another mode such operation may be effected periodically via a generator 69 and in a third mode changes in characteristics such as amplitude, slope of trailing edge or frequency of the signal to be recorded as derived from a preamplifier 62 are sensed by a circuit 70 and utilized to control trigger 66. Fig. 7 shows an arrangement in which the amount of the shift "S" (Fig. 5) is made proportional to the average amplitude of the preceding recorded signal. This is achieved by supplying the input signal via a second pre-amplifier 72 to an averaging circuit 7 the output of which is fed via gate 74, rendered conductive by a timing circuit 75 under the control of trigger 66, to an adder 71 in which it is combined with the signal to be recorded from pre-amplifier 62, so that the average level signal addition acts as a vertical shift voltage.
