Title: Method and apparatus for recognizing coloured pattern
IPC: G01J3/46
Filed: 1974-07-08
Abstract: 1478062 Coloured pattern recognition AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 8 July 1974 [6 July 1973] 30241/74 Heading G1A A coloured pattern comparing method comprises scanning across the pattern and detecting spectral distribution of light from each element of the pattern and comparing this with a memorized distribution and generating a multibit-binary output indicative of whether the light level at each wavelength of the element is within a predetermined range. In the embodiment of Fig. 3, light from each element of pattern 11, which is attached round rotatable drum 12, is split by prism 15 into a spectral bands separated by slits in plate 16. Photo-electric converter 17 provides electric signals corresponding to the transmittance or reflectance, compared in comparator 18 with reference signals from memory 19 so that, according to whether the signal from 17 is within a certain magnitude range, a signal of 0 or 1 is produced for each colour band of each element. This range may be between constant magnitudes or constant fractions of the transmittance or reflectance, Converter 20 forms a colour code applied by output 21 to a pattern forming system. The apparatus may provide information for only a single colour for printing cloth. Control circuit 13 develops a synchronizing signal for items 12 and 18-21. In the embodiment of Fig. 4, the prism 35 rotates so that the colour bands successively pass through the slit in plate 36. Signals from detector 37 are applied to ultrasonic light modulator 38a in optical real time correlation device 38 supplied by laser beam L. Signals from memory 39 are applied to modulator 38c. The correlation image is detected photo-electric conversion surface of element 40 and converted to a colour code in converter 41, so that output 42 supplies an electrical signal train to a punched tape recorder.

[Class 38 (v)] The electromagnetic switch of Specification 635,135 is combined with a thermally-responsive overload device comprising a bimetal strip 17 in each phase and anchored at 18, 19. The free ends of the strips 17 bear on adjustable screws 20 in a spring-urged pivoted member 23 which carries a lever 25 having a surface 26 engaging a lever 28 pivoted on a block 29 .in a lever 31 which is adjustable about a pivot 30. On overload, the member 23 is rotated counterclockwise by one or more of the strips 17, thereby moving the surface 26 into alignment with a recess 32 in the lever 28, which moves down under the action of a spring 27 to separate auxiliary contacts 1, 2 in the circuit of the closing coil. The circuit-breaker is reset by depression of the " stop " button 16 of the electromagnetic switch, which causes a curved part 33 of the lever 28 to bear on a stop 34 so as to flex the recessed part of the lever upwards, thereby allowing the lever 25 to move beneath lever 28 again. The contacts 11, 12 are reclosed by depression of button 15 which closes contacts 1, 2 to energize the closing coil, thereby swing- ing clockwise a lever 4 on the armature so as to hold contacts 1, 2 closed by means of an insulated bolt 14, the contacts 11, 12 being closed through a toggle 5, 7, as in Specification 635,945. The lever 25 may be bimetallic for ambient temperature compensation.

Title: Improvements in and relating to servomotor control systems
IPC: F02B71/04
Filed: 1964-08-04
Abstract: 1,056,930. Correspondance control systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 4, 1964 [July 29, 1963], No. 30898/64. Heading G1N. In a servo control system which controls a voltage magnitude in accordance with a reference voltage magnitude, hunting is reduced by adding a correction voltage of a polarity to reduce the difference between the said magnitudes, so that the servomotor is de-energized before the said magnitudes are equal. In Fig. 1 a series D. C. motor 1 controlled by a comparator 2 (which compares the said magnitudes) and supplied from a D. C. source 6, drives a potentiometer arm 9 via a coupling and gears 7, 8. The voltage to be controlled, is a voltage KU4 across the lower portion of the potentiometer 3, and a reference voltage U5 is obtained from a source 5. A correction voltage r#U originating from capacitors C15, C16, is applied in series with the loop so as to reduce the difference between KU4 and U5. A coupling disc 11 on the motor shaft frictionally engages and rotates a ring having a contact arm 12 so that the arm engages fixed contacts 13 or 14. In the state of equilibrium the motor oscillates at a frequency determined by the inertia of the system so that capacitors C15, C16 will be charged at the voltage of a source 21, and when the motor is at rest the arm 12 hangs vertically downwards. In operation, assuming U5 is increased then the comparator 2 will switch on the motor to rotate it clockwise and move the arm 9 to increase the voltage KU4. Simultaneously the arm 12 engages the contact 13, and capacitor C15 will remain charged while C16 discharges through resistors R18, R20. Initially the voltages across C15 and C16 are equal and in opposition. As C16 discharges there will be a gradually increasing voltage difference across the combination C15, C16, as follows:-   #U = U21 (1-e <SP>-t/RC</SP> ) where C = C16 and R=R18+R20. and across R19, R20 there will be a proportional portion r#U of the voltage difference. With respect to the comparator 2 this portion is added to KU4 so that KU4 + r#U # U5 and the comparator switches off the motor before the arm 9 has reached the point where KU4 = U5. The motor does not stop immediately but will run on to a point where KU4 = U5. If this point is not reached or is overrun, the motor is again energized and the sequence is repeated, the motor rotating in the required direction to reduce the said difference; the comparison device first responding to the real voltage difference (KU4 - U5) or (U5 - KU4) and then the voltage #U increasing from a zero value. When the arm 12 engages contact 14 the correction voltage is subtracted from KU4. In an alternative embodiment Fig. 2 (not shown) an oscillatory motion of the motor 1 in the equilibrium state is not required to maintain C15, C16 charged. The values of C15, C16 are chosen whereby #U increases proportionally to the square of the motor speed.
