Abstract: 1312947 Shift registers INTERNATIONAL BUSINESS MACHINES CORP 12 June 1970 [30 June 1960] 28514/70 Heading G4C [Also in Division H3] A bidirectional dynamic shift register comprises a plurality of data storage elements each provided primarily by the inter-electrode capacitance of a single field effect transistor, the storage elements being interconnected by shiftpulse-responsive means formed of field effect transistors. In the shift register of Fig. 3 using MOSFETs, shift right is done by using clock pulse # 1  to charge mode capacitance CNI via Q1, then # 2  to discharge CNI via Q2 and Q3 if the data input from CN2<SP>1</SP> is high, then # 3  to charge CN2 via Q6, then 94 to discharge CN2 via Q7 and Q8 if CNI was not discharged. Shift left is similar, using circuits shown activated by clock pulses # 1 , # 2 <SP>1</SP>, # 3 , # 4 <SP>1</SP>. The stored information can be regenerated by applying pulses # 1 , <SP>9</SP> 2 <SP>1</SP>, # 3 , # 4  to cause shift from CN2 to CN1 and back again, or # 1 , # 2 , # 3 , # 4 <SP>1</SP> to cause shift from CN2 to CN1<SP>1</SP> and back again. In the shift register of Fig. 7, shift right is done by using # 1  to charge node capacitance CNI via Q4 and Q6 unless the voltage across CN2<SP>1</SP> is high to provide a shunt to ground via Q5, then # 2  to charge CN2 via Q7 and Q9 unless CN1 was charged thus providing a shunt to ground via Q8. Shift left uses similar MOSFET circuitry in the bottom half of the figure activated by block pulses # 1 <SP>1</SP>, # 2 <SP>1</SP>. Bidirectional shift means may interconnect non- adjacent storage elements. Integrated circuits may be used.

Title: Improvements in and connected with electric regulating systems
IPC: G05F1/00
Filed: 1920-10-12
Abstract: 173,886. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Oct. 12, 1920. Regulation, automatic systems and apparatus for.-A regulator comprises two rotary make-andbreak devices co-operating with each other to vary the relative periods of make to break of the circuit to be regulated. A resistance R, Fig. 1, is intermittently inserted in the circuit of the field winding f of a generator G for varying intervals of time by means of two commutators 1 and 2 driven by motors M, M<1> respectively. The motor M is designed so that its field operates on the straight portion of the saturation curve in order that its speed may remain substantially constant when a change of voltage across the mains L, L<1> occurs. The field circuit f<1> of the motor M contains a resistance R<1> by means of which its speed may be fixed at varying values and it may be supplied with an additional field winding f' shunted across a resistance R<2>. The motor M' is designed so that its field operates beyond the bend of the saturation curve in order that its speed may be proportioned to the voltage across the mains L, L<1>. The terminals of the resistance R are connected to brushes 9, 10 engaging commutator segments 5, 6. The segments 5 are connected to rings 3 and the segments 6 to rings 4, while the rings 3, 4 of the commutators are connected through brushes and leads 7, 8 respectively. When the brushes 9, 10 engage corresponding segments of the commutators the resistance R is short-circuited and a variation in the speed of the motor M<1> due to a change of voltage across the mains L, L<1> causes a relative displacement of the commutators and a consequent insertion of the resistance R in the field circuit f of the generator for a greater or less period of time depending upon the value of the displacement. In a modification, the commutators control the field circuit of the exciter of an alternator, the motors being connected to the direct current side of a rotary converter. The field circuit of the exciter is made and broken for varying intervals of time, and the field is shunted by a discharge resistance. In the modification shown in Fig. 3, a resistance R<4> in the circuit of the field winding of the exciter E is controlled by two commutators 17, 18. The commutator 17 is driven by an induction motor M<2> having shortcircuited rotor windings and consequently a constant speed upon variable-voltage mains; while the motor M<3> has a resistance R<5> in its rotor circuit in order that its speed may vary with the voltage of its supply mains. In the modification shown in Fig. 4, the motors drive brushes 27, 28 engaging a, stationary commutator 29 having two or more segments. The brushes are connected to the terminals of the regulating-resistance through slip-rings 30, 31.
