Title: Conversion and Calculating Arrangements Employing Logarithmitic and/or Exponential Relationships between Input and Output Quantities

Abstract: 1,195,262. Logarithmic/exponential analoguedigital and digital-digital converter; calculating apparatus. INTELLIGENT INSTRUMENTS Inc. 20 June, 1967, No. 28356/67. Headings G4A and G4H. Analogue-digital and digital-digital converter.-By controlling the frequency of a unijunction transistor relaxation oscillator 99, Fig. 4, (circuit-Fig. 1, not shown) to be proportional to the count in a multi-cathode type counter 100 (Fig. 3, not shown), which also counts the pulses from the oscillator, the count( and the oscillator frequency) will rise exponentially with time, and thus if counting is allowed to continue for a period proportional to x, either by direct control of the oscillator or by a gate between the oscillator and the counter, then the final count will be proportional to e<SP>x</SP>. Frequency control of the oscillator is effected by a feedback form appropriately weighted cathode resistors in the counter. Digital-to-analogue and digital-to-digital conversion is effected by allowing counting 100, Fig. 5, to continue until the count 109 is equal to the digital input 111, and by using the coincidence signal 112 either to gate out the level reached by a linear sawtooth generator 114, or to stop constant frequency clock-pulses 119 passing to a second counter 121, respectively. In both cases the conversion is logarithmic. Exponential digital-to-digital conversion can be effected by inserting a number in counter 121 and by allowing counting to continue in counter 10 (starting from zero) until counter 121 has been stepped backwards to zero by the constant frequency clock-pulses. Calculating apparatus.-The above logarithmic and exponential digital-digital conversions can be used to effect multiplication of division. Thus, for multiplication for example, counting 121 of clock pulses 119, Fig. 6, continues until the count 100 of exponential pulses 99 equals the multiplier 111; then counter 100 is zeroized and counting 121 of clock pulses 99 continues until the count 100 of exponential pulses 99 equals the multiplicand; and finally counter 100 is again zeroized and counting of exponential pulses 99 recommenced until the counter 121 has been stepped backwards to zero by the clock pulses 119. The product then stands in counter 100. Division is similar, the only difference being that counter 121 must count backwards when the divisor is being entered. The quotient, like the product, appears in counter 100.

Filed: 1974-06-26
Abstract: 1519953 Measuring displacement and velocity electrically NATIONAL RESEARCH DEVELOPMENT CORP 26 June 1975 [26 June 1974] 28376/74 Heading GIN [Also in Divisions G3 and H2] A linear induction actuator incorporates a capacitive position transducer for indicating the position of a movable conductor relative to a fixed winding and fixed magnetic member. In the arrangement shown, an aluminium tube 26 is mounted on a shaft 28 between a fixed iron tube 21 and a set of coils 22 mounted on a fixed stainless steel tube 24, and energization of the coils 22 causes the tube 26 and shaft 28 to move axially to adjust a valve-member (not illustrated). For sensing the position of the tube 26, electrical contact is made with the tube 24 and with two independent sections 32, 33 of the tube 21 so that a pair of capacitors C 1 , C2 are effectively formed by the tube 24 and the respective sections 32, 33, the capacities of C 1  and C 2  varying with the axial position of the tube 26. A bridge circuit in a servosystem, Fig. 6, is used to compare C 1  and C2, and the output from a detection system 44, 43, 49, 62 provides a signal representing the position of the tube 26. A signal representing the velocity of the tube 26 is taken from a resistor 59, as described in Specification 1519954 (Division G1). The position and velocity signals are used to provide retro-active control of the actuator (Division G3).

Abstract: 1302636 Fluid-pressure servomotor systems WALWORTH CO 17 June 1971 [6 July 1970] 28489/71 Heading G3P [Also in Division F2] A stepped seat ring 66, 68 in a valve such as a rotatable ball plug valve, is sealed on two diameters D3, D4 by means such as the O-rings 84, 86, and carries a seal ring 72 which engages the valve member or plug in closed position. The effective sealing diameter of the ring 72 is intermediate the diameters D3 and D4. Arrangements are made for placing a chamber 88 between the rings 84, 86 selectively in communication with the upstream or downstream pressure, through duct 94 and lines 96a, 98a, so that the seat can be urged into sealing position against the ball or eased away from the ball to allow the valve to be readily moved between closed and open positions. As shown, the valve may be automatically regulated in response to some particular fluid characteristic e.g. pressure. For example, a controller may generate fluid-pressure signals ranging from 3 to 15 p.s.i. with either the maximum or minimum signal being set to initiate regulation. The signal is transmitted to a piston operated spool valve 112 operative to connect the duct 94 to either the upstream or downstream line 96a or 98a, so that the seat will be eased when the valve is required to make a corrective movement and urged to sealing position when the valve should be closed. In an alternative embodiment, the seats are controlled by two manually operated valves (102, 104) Fig.2 (not shown).

A motion controlling device for arresting and imparting movement to a trolley along a track has, overlying the track, a pusher member which in the blocking prevents movement of the trolley and actuating means which engage the pusher member when in the actuating position to impart movement to the trolley. A cross-pin 14 mounted on a trolley 12 travelling in the direction of arrow 46 on a track 10 first contacts and rotates in a clockwise direction a dog 32 mounted on plates 15 pivoted on pin 20 and then a dog 29 which is prevented from rotating by a pin 37 and thus brings the trolley 12 to rest. The arresting of the trolley 12 which tends to rotate plates 15 about the pin 20 is cushioned by compressed air supplied under pressure to a cylinder 16 through a pipe 44. The trolley 12 is pushed along the track 10 by the dogs 32 engaging the cross-pin 14 when compressed air is passed firstly through a pipe 58 to move a plunger 56 and release a latch bar 47 from a pin 52 on the plates 15 and secondly, upon the operation of a valve 43, through a pipe 45 into the cylinder 16 to pivot the plates 15 about the pin 20. The plates 15 are swung back to their normal blocking position by again passing compressed air into the cylinder 16 through the pipe 44. In an alternative arrangement, Figs. 5 and (i, the trolley runs along a track comprising a pair of opposed channels 62, 63, and carries rotatably mounted dogs 60, 61; the stop and feeding device is attached to a plate 64 mounted on the channel 63. A stop and pusher bar 69, pivoted at 70 has one end which normally extends across the path of travel of the trolley whilst the other end is connected to a rod 68 of an operating cylinder 66 and through a link 75 to an auxiliary stop bar 72 pivoted at 73. The trolley on reaching the blocking position, Fig. 5, with the stop arm 69 lying between the dogs 60, 61, is pushed to the right by passing compressed air, firstly to a cylinder 78 to lift a latch bar 76 by means of a plunger 84, and secondly into cylinder 66 to rotate the member 69 which presses against the dog 61 to move the trolley forward and at the same time to rotate the auxiliary stop bar 72 into the blocking position across the back.
