Title: Improvements in or relating to capacitance measurement circuits
IPC: G01R27/02
Filed: 1963-11-18
Abstract: 1,001,806. Measuring capacitance; measuring pressure electrically. ROSEMOUNT ENGINEERING A.G. Nov. 18, 1963 [Dec. 4, 1962], No. 45467/63. Headings G1N and G1U. [Also in Division H3] A circuit for comparing the capacity of first and second capacitors (23, 24, Fig. 3), each capacitor being a set having one or more capacitances per set, is arranged so that two sets each of two diodes, 27, 32 and 33, 36, are each connected to a first plate of each capacitor. The two diodes of each set have opposing polarity terminals connected to the appropriate plate. A load 38 and filter capacitor 40 are connected between the diodes 27 or 36 of one set and the diodes 33 or 32 of the other set. An alternating e.m.f. 26 is applied between a second plate 14 of each capacitor and the diodes 32, 33, and an indicator 39 responds to current flow in the load 38 to compare the capacity of the two capacitors. In the event of a difference in capacity between the capacitors 23 and 24, the current flowing to the capacitor 40 from the diodes 27 and 36 differs, and a resultant current flows through the load 38, to be measured by the meter 39. The arrangement is said to be suitable for accurately detecting small capacitance differences, such as occur in a capacitive differential pressure transducer (Fig. 1) where a conductive diaphragm 14 moves between two fixed capacitor plates 17, 18 in response to pressure differences between fluid pressures in the pipes 19 and 20. An arrangement which avoids connecting a high e.m.f. to the plates 14 and enables them to be at earth potential, wherein the energizing voltage is transformer coupled into the circuit, is described (Fig. 4 not shown). It is desirable that the frequency-amplitude product of the oscillator output should remain constant, and suitable conventional circuitry for achieving this is described (Fig. 6-10 not shown). In some applications it is desirable to use an amplitude modulated signal source (Figs. 11-14 not shown), and one described arrangement provides for automatic balancing of the differential capacitor arrangement (Fig. 15 not shown). Suitable circuitry for the oscillator in the A.C. source is described (see Division H3).

Abstract: 1,124,066. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORP. 5 Nov., 1965 [11 Dec., 1964], No. 46925/65. Heading H4P. [Also in Divisions F2 and H1] A serial to parallel or parallel to sequential converter comprises a mechanical rotary switch and a clutch. Clutch mechanism.-Upon applying a pulse to electromagnet 35, Fig. 1, continuously rotating cam 43 permits arm 32 to pull wire 30 rightwards. This action moves leaf spring actuator arm 24 to the right, which pushes pawl 27, which with arm 24 is mounted on disc 21, through a slot 45 in fixed ring 10 to engage the continuously rotating ratchet 11. As it is rotated pawl 27 passes behind ring 10 so that it is maintained in engagement with the ratchet until it reaches the slot 45 again whereupon cam 77 releases the pawl which comes to rest against stop 73 and anti-bounce spring 76. An alternative embodiment of the clutch, Fig. 7 (not shown), employs a hinged projection on ring 10 so that the clutch remains engaged and rotating until a rightward movement of arm 24 moves the projection to urge pawl 27 away from the ratchet to engage the stop 73. Serial to parallel conversion.-Serial signals energizing magnet 35 cause arm 32, rotating since the clutch is engaged, to pull arm 24. The motor driving the clutch and cam 43 is synchronized with the serial signals, so that arm 24 is adjacent a latch 55, Fig. 2, as each pulse is received, there being a plurality of such latches equally spaced about fixed ring 46. Movement of latch 55 releases bell crank 48 allowing contact 61 to close. At the end of one revolution the serial signals have been stored as closures of selected contacts 61. The contacts are reset at the end of the cycle by electromagnetically operated ring 65, Fig. 1, which has arms 64 which butt against arms 63 of the cranks 48 so that they are relatched. A cam ring 71 is provided, having apertures as shown, so that arm 24 can move a latch 55 only when that latch appears in the aperture. A further embodiment, Fig. 6 (not shown), has cranks 97 co-operating with arm 24. When rotated an arm on the crank allows an associated disc (107) to rotate slightly and close a contact. There is one such disc per crank. Parallel to sequential conversion.-On depression of a character key a pulse is applied to magnet 35, causing the clutch to engage, and a selection of Bowden wires 82 representing the character moves brackets 81 to the position shown dotted. As disc 21 rotates, magnets 96 close reed switch 92 to provide clock pulses to operate arm 24 via the magnet 35. Each latch 55 is moved in turn, arm 59 meeting bracket 81 and closing contact 84. Cranks 48 are prevented from unlatching by continuous energization of solenoid 78. In the embodiment of Fig. 6 (not shown), the cranks 97 operated by the arm 24 engage the selected Bowden wires to close the contacts. The discs 107 are locked in this instance.

An electric fence energizing circuit supplies periodic pulses to the fence and aperiod higher voltage pulses consequent on the fence being touched or displaced. The periodic pulses may be developed in a relaxation oscillator comprising transistor 31 and the aperiodic pulses by a monostable circuit including transistors 44, 45, both circuits having a common output transistor 36. A capacitor 33 is charged through a resistor 34 firing transistor 31 which discharges capacitor 33 through resistors 35, K32, K36, conduction of transistor 31 also firing transistors 32, 36 which discharge a previously charged capacitor 37 through the primary winding of a transformer 40. A damped oscillation occurs in the fence wire on the re-opening of transistor 36. When an animal charges the fence, an impulse generator 6 delivers a pulse through transformer 43 to a transistor 44 which through transistor 45 fires transistor 36 again discharging capacitor 37. Resistor 46 is adjusted so that the discharge period of the capacitor 37 is longer than that set on resistor 35. The impulse generators 6 comprise a displaceable permanent magnet core in an inductor (Figs. 7 and 9, not shown), the inductor being normally shortcircuited by contacts or a diode. In another arrangement (Fig. 5, not shown), the periodic pulses are provided by a first relay circuit and if the periodic oscillations are artificially damped by animal contact a second relay circuit supplies higher voltage pulses. An arrangement is incorporated to limit the number of aperiodic pulses delivered in any period. A circuit of the second type may be incorporated in Fig. 6.
