Since the Moon's orbit centers on the Earth, rather than the Sun, it would be a little confusing to think of the Moon's orbit as a year. Instead, this cycle of the Moon orbiting the Earth is much closer to our calendar system of months. It takes 27.322 days (or 655.728 hours) for the Moon to orbit the Earth. If that number looks familiar, it's because the orbital period of the Moon is exactly the same as its rotational period.
A self-sealing stem bolt. Self-sealing stem bolts are a basic component of reverse-ratcheting routing planers. (DS9 episodes: Progress, Prophet Motive) They consist of 80% mixed duranium, aluminum, and steel alloys, 11% electrically modulated ceramic, and 9% thermally stabilized plastic.
The gland becomes self-sealing once the internal steam pressure is sufficiently high. Initially there is no internal steam pressure and the external gland steam supply is required to prevent air ingress at the glands and thus allow condenser vacuum to be established prior to rolling the unit.
