Abstract

The recording of operating time of systems and components is facilitated with a mercury microcoulometer, or ampere-hour meter, having a base contained slidable re-zeroing scale, and a symmetrical and reversible housing containing the mercury tube for rendering the coulometer adaptable to a change in a) the direction of current flow, and b) the position of the electrolyte gap.

Moveable Reversible Operating Time Indicator

The recording of operating time of systems and components is facilitated with a mercury microcoulometer, or ampere-hour meter, having a base contained slidable re-zeroing scale, and a symmetrical and reversible housing containing the mercury tube for rendering the coulometer adaptable to a change in a) the direction of current flow, and b) the position of the electrolyte gap.

As current is applied through lead 15, clip 10, post 3, wire electrode 5, tube 6, wire electrode 4, post 2, clip 11, and lead 16, or vice versa, and electrolyte gap 7 traverses the length of tube 6 (where the direction of gap movement is from cathode to anode). The coulometer can be re-zeroed at any time by sliding scale 12 which is viewable through transparent window 8, back and forth in channel 14 relative to gap 7 without reversing the direction of current flow. Should there not be sufficient space remaining between gap 7 and the end of tube 6, then cover 1 carrying tube 6 can be removed from the base; being detachably mounted and maintained on the base by means of protuberances such as 9 engaging slots, such as 13. When housing 1 is disconnected from the base, turned around, and again connected, scale 12 may be repositioned and/or reversed on plane 14 for re-zeroing gap 7.
