Pneumatics question

I'm new to pneumatics and want to know what Ox designates. (My guess is outside air sensor). This stuff is fifty years old or more and still works (with a little attention).

    Need a bit more info...

    "X" sometimes refers to a restrictor, outside air sensors are usually LP914's, and are designated by their insertion type; well, duct or through the wall mounting.  It could also be a misprint of "Dx" which could mean direct expansion cooling, or a Direct Action (air-to-close) the valve or damper.
