Abstract
An inexpensive, compact and yet highly accurate instrument for transmitting coded signals representing altitudes at which an aircraft is flying, the instrument comprising an altitude sensing unit and a separate encoding unit operatively connected to the sensing unit with means for finely and precisely adjusting the encoding unit relative to the altitude sensing unit.
Claims13
Encoding means for altimeters or the like comprising
- a frame,
- a fluid pressure actuated device including a drive gear rotatably supported by said frame;
- an encoding device including an encoder disc and a pinion connected to said encoder disc;
- said pinion being engageable with said gear,
- a support for said encoding device,
- means on said frame forming a bearing,
- an adjusting member supported by said bearing for rotational adjustment about the axis of said bearing,
- said adjusting member supporting said support with the axis of said pinion eccentric to the axis of said bearing whereby said adjustment of said adjusting member will adjust said pinion relative to said gear, and
- means for sensing the position of said encoder disc relative to said support.

Encoding means for altimeters or the like comprising
- a frame,
- a fluid pressure actuated device including a drive gear rotatably supported by said frame;
- an encoding device including an encoder disc and a pinion connected to said encoder disc;
- said pinion being engageable with said gear,
- a support for rotatably supporting said pinion and said encoder disc,
- means on said frame forming a first bearing,
- an adjusting member supported by said first bearing for rotational adjustment about the axis of said first bearing,
