Abstract: 822,719. Electrical remote indicating system. EVERSHED & VIGNOLES Ltd. March 18, 1957 [March 22, 1956], No. 8993/56. Class 40 (1). In an electrical remote indicating system in which a moving element 30 to which the quantity to be indicated is applied in the form of a force or a torque P and in which this force P is balanced by a coil 26 (attached to element 20) and pot magnet 27, the current for exciting the coil is derived from the anode circuit of a triode 3. An aluminium vane 19 on member 20 moves between two coils 15 and 17 hence affecting their coupling and thus the rectified potential applied across capacitor 33 to the grid circuit of the triode. The primary coil 15 is energized from a high frequency transistor oscillator indicated generally at 1. The anode circuit also includes an indicator 40. A bias across resistor R3 is arranged to cancel out the grid potential produced when vane 19 is so placed that the mutual inductance between coils 15 and 17 is a minimum, that is when P is zero, and an auxiliary anode supply is provided from 45 through rectifier 46 to enable the indicator 40 to have a zero reading when the current through the valve is only that due to the minimum inductance position of vane 20 mentioned above. The two parts shown in the Figure as A and B may be widely separated. Specification 589,423 is referred to.
