Patent GB-439589-A (GB)
Abstract: 439,589. Indicating, recording, and integrating apparatus. ELECTROFLO METERS CO., Ltd., Abbey Road, Park Royal, London.-(Republic Flow Meters Co., Inc. ; 2240, Diversey Parkway, Chicago, U.S.A.) Oct. 24,1934, No. 30551. [Class 106 (iv)] A remotely-controlled indicating, recording, or integrating instrument comprises a solenoid moved by a remotely-controlled current and connected by a pin - and - slot connection with an indicating, recording, or integrating member whereby said member moves in a substantially linear relation to the remote varying quantity. The current in a solenoid coil 70 varies with variations in the quantity to be measured, an armature 68 pivoted at 62 being correspondingly drawn into the coil. A member 80 is secured to the shaft 62 and pivotally carries at 82 a stirrup 84 having a slot 86, Fig. 6, engaging a pin 94, on a lever 96 to which is attached a pen arm 18. The action of the pin 94 and slot 86 provides the correction for the deviations from a straight-line law in the action of the solenoid 70. The pin may be attached to the stirrup 84 and the slot formed in the lever 96. The instrument may be adjusted by turning the stirrup 84 relative to the member 80 about the pivot 82, this being effected by teeth 88 on the stirrup which are engaged by a screwdriver resting in an aperture 92. The arm 18 is supported by a carrier 98 and is adjustable relative to its supporting and driving means by a screw 102 on the carrier 98 having an eccentric collar engaging the lever 96. A circuit whereby the apparatus is connected to a fluid-flow meter is shown in Fig. 11. A contact 118 is moved by the fluid head along a resistance 116 arranged to take account of the square-root relationship between head and flow, the resistance being connected to the source of supply 120 and to the coil 70. Another coil 72 connected across the supply 120 provides both a restoring force and a means for compensating for variations in the supply voltage. In another arrangement, Fig. 15, a contact 158 is moved over a resistance 148 in accordance with temperature variations and is connected to two solenoids 170, 172 through which the armature 68 passes. Specification 211,237, [Class 106 (iv)], is referred to.

Title: Display editing apparatus and method therefor
IPC: H03K21/08
Filed: 1972-09-25
Abstract: 1404325 Zero suppression SOLARTRON ELECTRONIC GROUP Ltd 25 Sept 1972 [24 Sept 1971] 44172/72 Heading G4H Zero suppression for a display is performed by producing a display inhibit signal in response to joint occurrence of a first signal indicating a zero digit, a second signal indicating that the preceding digit is an unwanted zero or that the current digit is the first digit, and a third signal produced when the current digit is not immediately adjacent to the decimal point. A binary-coded-decimal count (4 decimal orders) is gated into storage latches in parallel, then passed serially-by-decimal-order, parallelby-bit by a multiplexer to an encoder for conversion to 7-segment form, the encoder output going to a series 7-segment displays in common. The displays are enabled in turn (most significant to least significant) by a scanner which also controls the multiplexer. Leading zeros are blanked by a signal at 103 (Fig. 4) applied to the encoder. The encoder notifies a zero digit to the Fig. 4 circuit on line 94 to AND 104. If AND 104 produces an output this is the blanking signal at 103 and through AND 109 &c. can set a flip-flop 121. An OR 106 provides an enabling input to AND 104 if this flip-flop is set or the current digit is the first (most-significant) under control of line 60 which is one of the scanner output lines 60, 59, 58, 57 which are energized in that order. If a set signal is not applied to the flip-flop for a given digit, a reset signal will be (via inverter 119). A decimal point selector 99 controls the logic as shown to modify the operation in accordance with the decimal point position. Thus inverter 112 will prevent setting (cause resetting) of the flip-flop in response to a blanked zero immediately preceding the decimal point (since if the next digit is a zero it must not be blanked), Switch 130 is set at the factory according to whether the decimal points are to the left or right of the digits. When line 57 is energized, any blanking signal at 103 is prevented from reaching the encoder by an inverter and gate (not shown in Fig. 4). Trailing zeros may be blanked instead, by reversing the scanning order &c. If the count exceeds 2000, under control of the latches, counter and scanner, the encoder replaces the most significant digit by a 1 which is blinked, and the other digits are blanked.

C. engine having a combustion chamber and an ignition system for periodically igniting fuel in the combustion chamber comprises a Piezoelectric accelerometer 1 coupled mechanically to the engine head and transducing engine vibrations into a train of electrical signals characteristic thereof, a gate 8 of which a signal input is connected to the accelerometer output and controlled in dependence upon the ignition system so as to block signals at the gate input except during a predetermined interval in each operating cycle of the engine, the interval commencing after a proportion of the period of the operating cycle has elapsed following ignition of the fuel in the combustion chamber the proportion being such that the pressure in the combustion chamber is at substantially its maximum value at the end of that proportion of the period and the gate being opened for an interval corresponding to 60 degrees to 80 degrees of each engine crankshaft revolution. The gate control signals are derived by an inductive probe 3 giving an output pulse for each ignition pulse which pulse is shaped at 4 to drive bi-stable multi-vibrator 5 delivering complementary pulse train signals 18, 19 to half-cycle integrators, of which one 6 employs signal 18 to charge an integrating capacitor at constant current to a peak voltage inversely proportional to the frequency of the ignition pulses. The integrator 6 provides two output signals to charge respective capacitors 16, 17 during each half-cycle of the signal 18 during which it is at level 1. In each following half cycle the capacitors are discharged at constant current, the discharge time constants of capacitors 16, 17 being chosen so that the capacitor 16 reaches a substantially fully discharged condition before the capacitor 17. The voltages across these two capacitors being applied to a logic circuit 9 applied to a control input of the gate 8. As indicated by the dashed line output from multi-vibrator 5 and dashed line input to gate 8 the signal 19 is treated in a similar manner to the gate 18.

Abstract: 1383062 Measuring corrosion rate PETROLITE CORP 28 Sept 1972 [11 Nov 1971] 44937/72 Heading G1N A corrosion ratemeter, including a three electrode probe and in which the current applied to auxiliary and test electrodes necessary to maintain a predetermined polarisation voltage on the test electrode relative to the reference electrode is measured to give the corrosion rate, automatically corrects for the freely corroding potential existing between the test and reference electrodes. Test 21, reference 22 and auxiliary electrodes 23 of the corrosion probe are connected to terminals T, T<SP>1</SP>, R and A of the ratemeter via selector switch 31. The bridge circuit comprising resistors 36, 37; 71 and 74 is initially balanced by adjustment of resistor 72 to produce a minimum output current from amplifier 66 connected across the diagonal of the bridge circuit when the probe is disconnected from the terminals T, R, T<SP>1</SP>, A and switches 76, 88 are in the "null" position shown. The circuit is then calibrated by connecting the "prover" to terminals R, T, A, T<SP>1</SP> so that the resulting bridge unbalance is fed to amplifier 75 to rebalance the bridge and then moving switches 76, 88 to the left hand measurement position so that the output from amplifier 66 is fed to the read-out means via the test electrode 21 and terminal T<SP>1</SP>, resistance 112 being varied to give the required scale reading. Measurement. Terminals R, T, A and T<SP>1</SP> are connected to probe 11 and switches 76, 88 returned to the "null" position. The freely corroding potential across the test 21 and reference electrodes 22 is applied to the bridge via terminals R, T and impedance converters 38, 39 to unbalance the bridge and produce an output at 69 which is applied to amplifier 75. A correction signal is stored in capacitor 78 representative of the freely corroding potential and at the same time current flows through resistors 37, 74 until inputs 67, 68 of the amplifier 66 are at zero potential difference. The correction signal is stored in capacitor 78 even after the probe 11 has been disconnected. Switches 76, 88 are moved to the left hand measurement position so that the output 69 of amplifier 66 is connected to terminal 96 and a reference signal  V r  provides a current signal in 36, 71, 89, 72 and 91 to change the potential at input 67 representative of the certain polarization potential to be created between the test and reference electrodes. As a result current flow produced by amplifier 66 flows between the test and auxiliary electrodes until the certain  polarization potential is established between the test and reference electrodes when the bridge is rebalanced. The current needed to rebalance the bridge is recorded at 103. Capacitors 62, 63 remove extraneous non D.C. potentials.
