Title: Improvements relating to systems for the remote indication of meter readings
IPC: G08C19/16
Filed: 1943-11-24
Abstract: 568,495 . Telemetering systems. GENERAL ELECTRIC CO., Ltd., and FIELD, R. W. G. Nov. 24, 1943, No. 19617. [Class 40 (i)] The meter pointer 1 whose position is to be repeated is coaxial with an auxiliary meter movement comprising a coil 4 operating a forked contact member 6, 7 embracing the pointer 1, and impulses are supplied to a distant indicating meter and to the coil 4 at a variable rate depending on the position of the pointer to cause the member 6, 7 to follow its movement. The repeating action takes place as long as relay MS is energized, and the impulses are generated by interaction between a pair of relays XM, YM the lower windings of which are shunted by equal resistances which are varied by means of two reversible rotary switches MSA, MSB. The coil 4 receives impulses of current through the charging circuits of two condensers CA, CB which charge and discharge alternately as relay XM vibrates. The switch MSA controls the insertion of a series of small resistances in the shunt circuits, while the switch MSB controls the insertion of a series of larger resistances, and the passage of the switch MSA through either of its extreme positions causes the switch MSB to move a step to increase or diminish the total resistance of the shunt circuits progressively. The movement of the switch MSA to change the rate of impulsing is initiated by relays RSA, LSA, one of which is operated when the pointer 1 engages an arm of the forked member 6, 7. Specification 432,606, [Group XXXIX], is referred to.
