The ammonia clock was the first atomic clock invented by the US National Bureau of Standards in 1948 that measured the speed of the vibrations of nitrogen atom in ammonia molecule.
An ammonia clock measures time based on the frequency of microwave radiation absorbed by ammonia molecules, while a caesium clock measures time based on the vibrations of caesium atoms. Caesium clocks are more accurate and stable compared to ammonia clocks, making them the standard for defining the international unit of time, the second.
An ammonia purger removes air and noncondensables from the ammonia system by directing vapor from the condenser, where air collects, through cold liquid ammonia. This condenses the ammonia and separates noncondensables which are then removed from the system.
Ammonia absorption refrigerators work by using a combination of ammonia, water, and hydrogen gas to create a cooling effect. The process starts with ammonia evaporating in one part of the system, absorbing heat and cooling the surrounding area. The ammonia gas then travels to another part of the system where it is absorbed by water, releasing the heat and returning to a liquid state. This cycle continues, with the ammonia gas being absorbed and released, creating a continuous cooling effect that efficiently cools food and beverages.
An anhydrous ammonia refrigeration system works by circulating ammonia gas through a closed loop system of pipes. The ammonia gas is compressed into a liquid state, which absorbs heat from the environment as it evaporates back into a gas. This process cools the space or equipment it is designed to refrigerate.

Hello, to work against the clock means that you have a limited amount of time to do something in.
The time keeper has a special device that controls the clock.
If you clock does not work in your Peugeot 206 when the stereo is plugged in, check the clock fuse. You should also ensure you do not have a wiring problem.

Usually you are given a card or number both sometimes to clock in and clock out of work you simply slide the card given or punch in the number your are given which is usually your work number authorized so remember it . You will see your log press your position you work and you are set the number of hours or time you clock in will be printed out instantly.
The clock is maintained by a certified NFL official. He or she takes cues to start and stop the clock from the referee.
It depends on which clock you have. Is it a Rhythm Small World Clock Does it have a monitor button?
The clock feature will depend on the Wii's time that you set it to.
