Title: Fluid Dispensing Apparatus.
IPC: G05D11/00
Filed: 1967-12-15
Abstract: 1,169,420. Dispensing liquids. VEEDER INDUSTRIES Inc. 15 Dec., 1967 [22 Dec., 1966], No. 57072/67. Heading A4T. [Also in Division B1] In apparatus for dispensing two fluids to a common discharge nozzle and at a pre-determined total flow rate in proportions controlled by an adjustable proportioning valve automatically adjusted to a preselected ratio, there is a flow control to close off the fluid flow to the discharge nozzle and to recirculate them to permit adjustment of the proportioning valve to a new ratio before delivery of the fluids to the nozzle. As shown in a conventional arrangement for dispensing two grades of fuel, they are pumped by pumps 16, 18 to a proportioning valve 24 through flow meters 30, 32. The proportioning valve 24 is adjusted by a subtracting differential 28 which has inputs from flow-meter 32 and from a speed changing mechanism 44 which is controlled by screening differential 38 and by variator 48 on which the preselected ratio is set. The return valve 72 has valve members 74, 76 each having two positions in which the incoming flow is either recirculated, or delivered to the discharge nozzle. At the end of the dispensing operation a handle 85 is turned to an OFF position to reset the number wheels 54 of a register 50, also operating a linkage 80 which moves the valve members 74, 76 to the recirculating position. When the nozzle 10 is next lifted from its storage position, the pump motors 20, 22 will be energized and the proportioning valve thus readjusted before the handle 85 is turned to the ON position to open flow to the discharge nozzle. Alternatively, the linkage so may be connected to a presettable control mechanism 88 for terminating delivery when preselected amount has been dispensed. In another embodiment (Fig. 3, not shown) the screening differential (138) provides an input to a differential (200) the output of which is transmitted to the variator (148) and to the register (150) by shafts (202, 204) having a variator brake (206) and a register brake (208) connected to a common brake control (210) for engaging one of them and simultaneously releasing the other. The brake control is operated by the return valve control linkage (180) whereby automatic resetting of the register is provided.

Title: Noise Suppression Circuit

Abstract: 1,159,270. Noise suppression arrangement. INTERNATIONAL BUSINESS MACHINES CORP. Dec.21, 1966 [Dec.29, 1965], No.57203/66. Heading G1A . A noise suppression circuit includes means responsive to pulse amplitude and pulse slope of a noise pulse to develop control signals, and a switch operated by the control signals. The invention is applied to the recording on a strip chart of the result of an opacity test in an automatic fluid analyzing system and the limits beyond which control signals are developed are predetermined from a knowledge of the system and of the type of noise which may be due for example to bubbles or other impurities in the liquid. The system shown includes a feedback arrangement in which the output from a potentiometer 20 driven by the recording transducer 16 is compared with the signal from the analysis device, the switch 52 operated by noise pulses being in the input to the recording transducer. In the noise suppression circuit, Fig. 5, the magnitude and slope discriminators each comprise three grounded emitter transistors and generate a positive outgoing pulse on lines 67 and 79 when the magnitude on line 51 falls outside limits +V 1  or -V 1 , and/or when a pulse produced by a differentiating amplifier 71 falls outside limits +V 2  or -V 2  respectively. Outgoing pulses in both lines pass through AND gate 96 and operate switch 52 through an electromagnet 99, a driving circuit 98, and a bi-stable latch circuit 97. The bistable latch is reset by a positive going pulse from inverter 92 when the signal on line 51 drops back or in the case where a step function with no drop-back is being recorded, a pulse is provided by a timing circuit 80 which is fed also with the outgoing pulse from the slope discriminator.

Title: Phase control apparatus for a rotary member
IPC: B26D3/26
Filed: 1973-12-14
Abstract: 1450434 Automatic control of phase and speed SONY CORP 14 Dec 1973 [18 Dec 1972] 58000/73 Heading G3R In a phase control apparatus for a rotary member e.g. a video tape recording head, first and second signals are generated when the motor reaches predetermined angular positions. A squarewave is generated that has a pre-set phase relationship with the first signal, and is compared with the second signal. The comparator is thus in one of three conditions, according to whether the second signal is lagging, leading or coincident with the squarewave. The rotation of the rotary member is controlled according to the comparator condition, a reference phase signal and at least one of the first and second signals. As shown, the first and second pulse signals are generated by position detectors 12a, 12b. The first signals from detector 12a sequentially triggers multi-vibrators 15, 16, and if a pulse from detector 12b occurs whilst multi-vibrator 16 is triggered on, a vertical synchronizing signal Sv passes via time delay 2 and NAND gates 4, 5 to integrator 6. The integration is sampled and held by 7 at the next pulse from either detector 12a, 12b whose outputs are summed by mixer 13. The held signal produces a motor control e.g. braking signal for motor 9 which may drive a rotary head in a video tape recorder, or drive a tape capstan. If the pulse from detector 12b occurs whilst multi-vibrator 15 is triggered on, or after the multi-vibrators have both reverted to their off state, the output from NAND gate 5 to the integrator 6 is respectively a '1' (overspeed) or '0' (underspeed) signal, producing a low or high motor control signal. The motor may be a D.C. or eddy current type, or a synchronous motor fed from a variable frequency oscillator.
