Sesquialtera [noun] - a compound stop always including a third-sounding rank. May contain the 12th and the 17th and be unbroken throughout its compass, as the non-unison partials and ingredients for a Cornet. Also can be found, particularly in English organs, as three or more ranks, with breaks.

Slider [noun] - a stop-action scheme (for turning individual stops on or off) having a strip of wood or metal under the pipes for a single rank, with holes drilled to admit wind to each pipe. When the stop is turned off at the console, the strip slides out of alignment, the windway is no longer open and the rank will not speak. The scheme can be used in mechanical-action and electric-action instruments. It is frequently considered more reliable than the pitman chest since it depends very little on leather as a component; but it can be noisy, particularly when a large number are thrown at the same time by a combination action.
Slider Chest [noun] - a wind-chest built on the slider stop-action principle, see above.
State Trumpet [noun] - A very large-scale chorus reed, usually mounted horizontally, a special form of Trompette-en-chamade.
