Factory

The term factory refers to an oscillator which produces separate non-glider spaceships or other oscillators or still lifes. The best-known and most common factory is the queen bee, which produces beehives, however without a cleaning mechanism, resulting in its own death. Factories are commonly used as memory cells, such as in a |demultiplexer. Some periodic factory mechanisms also stabilize themselves, like 51P384.
If the factory produces spaceships, it is much more commonly referred to as a gun. If it produces still lifes or oscillators, it will generally need other components to support it; the new object does not move out of the way, and therefore must be used up in a reaction or destroyed before the next one is made.
The following shows an example of a p144 gun, new gun 2, which consists of a slight modification of Achim's p144 whose output is used up in a reaction with blockers hassling an R-pentomino to create gliders. This gun is David Bell's improvement of a gun found by Bill Gosper in July, 1994, which is an arrangement where blocks eat the residual beehives of two queen bees which collide to create gliders every 30 generations.
