Title: Hydraulic actuator control system
IPC: F15B21/08
Filed: 1969-11-19
Abstract: 1,254,363. Electric correspondence control systems. MOBILITY SYSTEMS Inc. Nov.19, 1969 [Dec.9, 1968], No.56561/69. Heading G1N.  A light platform 10, Fig. 1, is raised and lowered by the piston 18 of a cylinder 20 fed from a hydraulic pump 24 in accordance with the difference between a command signal at terminal 52 and a lift position signal at the slider of a potentiometer 82 coupled to the lift platform 10. The difference is developed at 60, amplified at 70 and fed via a pulse-width modulator 72 to an AND gate 76, whose other input is a start command signal fed in at terminal 54, to allow the pulses to periodically switch on a transistor 46, the width of the pulses determining the average armature current of motor 34. The output from amplifier 60 is also fed via OR gate 100 to close transistor switch 44, thereby energizing the field circuit of motor 34, which accordingly drives the pump 24 and repositions the lift platform 10 until the difference signal is eliminated. A rate signal derived from tachogenerator 36 is incorporated in the circuit. A "raise lift" command signal produces a positive output at 60, which via unit 92 adds a bias input to amplifier 60 to overcome gravity: a "lower lift" command signal stops motor 34 and opens by-pass valve 28, causing the pump 24 to be driven backwards, thereby driving motor 34 as a generator and acting as a brake. In another embodiment the pump drives the cylinder piston through a doubleacting valve.

Title: Binary divider circuit
IPC: H03K3/289
Filed: 1973-12-10
Abstract: 1449874 Dividers INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1973 [29 Dec 1972] 57143/73 Heading G4A [Also in Division H3] A binary divider circuit has a slave crosscoupled bistable circuit Q13, Q14 and a master cross-coupled bistable circuit Q7-Q10 connected in series between first and second supply lines and a connection such as diodes D1, D2 bypasses current around the slave bistable to the master bistable so that the master bistable may provide a higher output power and/or faster switching speed than the above bistable. As shown in Fig. 3 the diodes D1, D2 carry the constant current drawn by the master bistable so as to provide an approximately constant voltage at line L to prevent each bistable circuit from interacting with the other bistable circuit as their impedances vary during their switching operations. The master and slave bistables are reset by an input at RESET IN which briefly causes Q19 and Q20 to conduct. This sets the master bistable so that Q7 is off and Q8 is on and resets the slave bistable so that Q13 is on and Q14 is off. When the input IN is up and input IN is down Q5 conducts and Q6 is off. Assuming the slave bistable is reset its output C is up so that the collector current of Q5 flows through Q1 thereby setting the master bistable so that its output A is down and its output 73 is up. When input IN goes down and input IN comes up Q5 is off and Q6 turns on. The collector current of Q6 flows through Q3 so as to set the slave bistable to make its output C go down and its output D go up. When the next cycle starts input IN goes up and input IN goes down. This time the collector current of Q5 goes through Q2 to reset the master bistable to make its output A go up and its output B go down. Next time the input IN goes down and the input IN goes up the collector current of Q6 now goes through Q4 to reset the slave bistable thereby completing the cycle of operations. The output of the binary divider may be either A and B of the master bistable or from C and D of the slave bistable. By suitable choice of the tapping points of R5<SP>1</SP>, R5 and R6<SP>1</SP>, R26 the voltage levels at the bases of Q7 and Q8 can be made equal to the levels at the bases of Q5 and Q6 so that the input of the next identical binary divider can be directly coupled to the bases of Q7 and Q8. The circuit includes Schottky barrier diodes SB1-SB10.

A more complicated adder is shown in Fig. 13 where partial products A 0 , D 0 , G 0 , H 0 , K 0 , No shown ringed are applied to gates as separate x and y bits. All other partial products are formed in threshold AND gates prior to bring supplied to the three or more input adders. The inputs to each threshold gate are the terms included in the brackets and the carry bits produced and supplied to the next more significant column are arranged and indicated in square boxes. Sum bits produced either as the final product or by threshold gates where more than one such gate is used to add the partial products in a column are shown in broken circles. The subscript in the final sum term indicates the significance of the stage while the superscript indicates the number of stage delays.
