    • n ejector In sheet-metal work, an attachment to a press for throwing out the finished stamped or drawn object while the die is rising and before the operator or the feed-motion places the next blank in position. The push-out plate used with presses employing double dies is a form of ejector. (See double dies, under die.) The stripper, on the other hand, is not an ejector, since it releases the work from the die only, without removing it from the press. See stripper.

In science:

An isolated NS can pass through four main stages of evolution: Ejector, Propeller, Accretor and Georotator (see Lipunov 1992 for detailed description of each stage).
Evolution of isolated neutron stars in globular clusters: number of Accretors
We consider, that all NSs are born as Ejectors, and then while they slow down (or/and their magnetic field decays) they pass through the Propeller and Accretor stages.
Evolution of isolated neutron stars in globular clusters: number of Accretors
For the Propeller stage one can find in the literature a lot of different spin-down regimes, but in the case of constant magnetic field the Propeller stage is always considered to be much shorter than the Ejector stage (see Lipunov & Popov 1995).
Evolution of isolated neutron stars in globular clusters: number of Accretors
Escaped NSs are considered as Ejectors as far as they have high spatial velocities and move in low-density surrounding.
Evolution of isolated neutron stars in globular clusters: number of Accretors
This effect will increase the duration of the Ejector stage (see eq.1), and correspondently decrease the number of Accretors.
