Title: Improvements relating to electrical indicating or repeating systems
Inventor: BOUNDY JAMES REILLY
IPC: G01R17/08
Filed: 1950-05-10
Abstract: 683,715. Electric indicating systems. EVERSHED & VIGNOLES, Ltd. May 10, 1951 [May 10, 1950], No. 11663/50. Class 40 (i). In an electrical indicating and repeating system a torque representing a quantity to be indicated is balanced by a counter torque produced by the unidirectional output current of a magnetic amplifier, flowing in a moving coil pivoted in a magnetic field, the input current to the amplifier being derived from a condenser whose state of charge is adjusted by a pair of oscillatory contacts controlled by the moving coil, any incipient movement of which produces a corresponding variation of the condenser charge of the input current and of the output current energizing the countertorque moving coil, which current is continuously regulated to a value proportional to the quantity to be indicated, and operates remote repeating instruments. A torque T representing an unknown quantity is applied to a spindle 1 e.g. by an energized moving coil 2 pivoted between permanent magnet poles 4, 5, and is normally balanced by a countertorque C due to a second moving coil, pivoted on spindle 1 between permanent magnet poles 7, 8, and carrying a contact arm 9 movable between fixed contacts 10, 11. When torque T overcomes torque C, contacts 9, 10 make to charge a condenser 12 through a variable series resistor 19 from the smoothed output of a rectifier 13 energized by transformer 15, and when torque C overcomes torque T contacts 9, 11 make to discharge the condenser through the resistor 19. The condenser is connected in series with high resistance 20 across the input a, b of a known magnetic amplifier 21 which is A.C. excited from transformer 15 and developes a unidirectional output signal at e, f, which after smoothing energizes moving coil 6 and repeaters 27, 28 through variable load resistance 29. For a constant value of the unknown quantity, the contact 9 oscillates between contacts 10, 11 alternatively increasing and decreasing the voltage across condenser 12 and the input to the magnetic amplifier, whose output similarly oscillates about the value which balances the torque T proportional to the unknown quantity. An increase or decrease in the latter respectively charges the condenser to a higher voltage or allows it to discharge to a lower voltage, and the output current of the magnetic amplifier similarly varies to restore balance between the torques at a current value which is proportional to the unknown quantity. Hunting is avoided by adjusting resistance 19 so that the rate of change of the input to the magnetic amplifier is equal to the rate of change of the output, and the residual output current of the amplifier for zero input is balanced out by a constant opposed current derived from the rectifier through resistance 32, repeaters 27, 28 and the moving coil 6, such that the indicating current is zero for zero input.

Patent GB-470590-A (GB)
Title: Improvements in and relating to electric switches in sealed containers
IPC: H01H37/28
Filed: 1936-04-27
Abstract: 470,590. Thermal switches. TRIGGS, W. W. (Edison, Inc., T. A.) April 27, 1936, No. 11986. [Class 38 (v)] The fixed contact of a thermal or other switch mounted within a sealed container may be adjusted and locked in the adjusted position after the container has been sealed. In the form shown in Fig. 1, in which a bimetallic strip 18 actuates a movable contact 32, the co-operating fixed contact 26 is mounted on a stem 25 slidable under gravity in holes in a member 21. The container may be immersed in a liquid to bring it to the temperature at which it is desired the contacts should operate. The fixed contact 26 is then slid by gravity till it touches the contact 32, this being indicated for example by a lamp in a circuit including the two contacts, and the contact 26 is then locked in position by passing a current through a fusible wire 39, which releases a spring arm 37 which moves upwards to engage and press against the stem 25. The device is held in the container by flat springs engaging its walls. In a modification, Figs. 6-10 (not shown), the fixed contact has an inclined contacting surface and is slidable under gravity and then locked in a similar manner by a fusible wire releasing a spring. Figs. 11-13 and 14-16 (not shown) show devices similar respectively to the above constructions excepting that the release of the spring locking member is effected by movement of an armature caused by the approach of an external magnet. Fig. 17 shows another form in which the fixed contact is a conical member 119 the,position of which may be adjusted by screwing it into or out of a frame 107. This is done by means of an external magnet the poles of which are brought opposite poles 121, 122 arranged on the member 119 and then slowly rotated. A spring finger 128 which may be retracted by vibration or another magnet serves to hold the contact in its adjusted position. In another form, Figs. 22-27 (not shown), the rotation of a similar external magnet causes the rotation of a screw which causes longitudinal movement of a rod carrying a pin which bears on inclined surfaces and is thereby raised to alter the adjustment of the fixed contact. Fig. 28 shows a form in which rotation of a magnet N, S rotates a screw 199 which bears on a cam 197 on the fixed contact 195, and in Fig. 32 (not shown), similar rotation of a magnet causes through worm gearing the movement of a nut along a screwed rod and thereby the tilting of a frame carrying both the fixed and movable contacts. The movable contact is in this case mounted on a spring engageable by the end of a bimetallic strip.

A fault condition detector 42 includes a fault level sensing adjuster, e.g. potentiometer 44, and. a timer 46 prevents false operation due to short transients. The output signal from the timer 46 is applied through an OR network 50 to a trip condition detector 54 to energize a trip output 60 and a trip network 68. The detector 54 also supplies an output signal to a timer 64 which through the OR network 52 maintains an input signal to the detector for a minimum trip duration sufficient to ensure operation of the circuit 68. The input to the transformer 1 may be the vector sum of the currents in two phase conductors of a three phase supply. A further transformer 1 energized by the vector sum of one of those currents and the remaining current, may supply further circuits 8, 20, 22, 28, 34 connected with the first circuit arrangement to an OR circuit 38.
