Patent GB-1201189-A (GB)
Title: Improvements in or relating to control apparatus
IPC: G05B15/02
Filed: 1967-09-25
Abstract: 1,201,189. Automatic control. HONEYWELL Inc. Sept.25, 1967 [Oct.25, 1966; Sept.26, 1966; June 21, 1967], No.43514/67. Heading G3R. A control signal or a stand-by signal is selected by switching means to adjust the value of a process variable, the control signal also being applied through second switching means for comparison with a desired value signal from a digital computer so that any error is effective through third switching means and an amplifier to produce the control signal, a manually controlled signal also being applied to the amplifier and all the switching means being controlled by the computer. In Fig.4, with a switch 500 in the "A" position and switches 405, 406, which may be transistors, in the "a" position, an amplifier 501, comparing the magnitude of a measured process variable with a desired value determined by the setting of a potentiometer 513, produces an error signal which is applied through an operational amplifier 88 to correct the variable by adjusting a process control element such as a valve 90. Resistance - capacity feedback associated with amplifier 88 introduces differential and integral components of control which may be modified for certain modes of control. With switch 500 in the "M" position and switches 405, 406 in the "b" position, the process variable may be controlled manually by operation of a potentiometer MANUAL. If switches 405, 406 are operated periodically between positions "a" and "b" under the control of a digital computer 87 the process variable is controlled by signals from the computer which are converted to analogue form and transferred to amplifier 88 through switches 405, 406 and the storage capacitor inter-connecting them. The output of amplifier 88 is then fed back to the computer through a switch K 3  and an analogue to digital converter 89 to eliminate error between actual and desired values of the output of amplifier 88. When in control, the computer closes a switch 522 so that a servomotor 521 controlled by the output of amplifier 501 maintains the setting of potentiometer 513 at a value corresponding to the magnitude of the process variable in readiness for smooth changeover to process control by amplifier 501. Failure of the computer causes switches K 2 , K 5 , to change over from the positions shown so that a back-up signal from a potentiometer PRESET adjusts the process control element 90 to a stand-by position. Switch 522 is also opened after a delay to prevent operation of servomotor 521, and control of the process by amplifier 501 is substituted.

Abstract: 1,196,298. Digital electric multiplier. ZENTRALEN INSTITUT PO ISTCHISLITELNA TECHNIKA. 3 Oct., 1967 [4 Oct., 1966], No. 44947/67. Heading G4A. The invention relates to a digital electric multiplier. A register R 1  containing a multiplier and a register R 2  containing a multiplicand are each of the same length and are capable of containing the product. A one-shot multivibrator 5 via gate 12 causes examination of the most significant digit of register R 1 . If the digit is zero gate 8 causes one-shot multivibrator to increase counter 17 by 1, causes contents of register R to be shifted one position in the direction of higher significance and causes examination of the most significant digit. This process continues until a digit is found that is non-zero whereon gate 7 causes an addition unit 1 to operate under control of a counter 2 operating via AND gate 16 to cause successive addition of corresponding digits of the two registers and when the most significant digits are reached causes via gate 13 and flip-flop 4 the most significant digit in register R 2  to change to 9. The result is stored in R 1 . If the most significant digit of R 1  is non- zero the process is repeated. If it is zero the number is shifted, the most significant digit examined and the whole process repeated until counter 17 determines that the process is complete, e.g. if R 1 =000312, R 2 =000154, then R 1  is shifted three times until R 1 =312000. The most significant digit is non-zero so R 2  is changed to 900154 and the two numbers added to give R 1  and R 2 =212154. R 2  is again added because the m.s.d. is non-zero to give 112308 and added again to give R 1 =012462, the carry each time being ignored. R 1  is shifted 124620 and R 2  added to give 024774. R 1  is shifted and R 2  added to give 147894 and added again to give the result 048048.
