RNE-19T84 is a converter that accepts an input R-pentomino and produces a glider heading northeast (if the R-pentomino is in standard orientation as shown in the infobox at right).
This converter has several common uses. Paul Callahan pointed out on October 29, 1997 that the beehive-and-eater constellation can be attached to the L156 Herschel conduit to change it into a useful period doubler. On November 11, 1998, Stephen Silver removed the Herschel output from the period-doubling L156 to produce a Herschel-to-glider converter:

The above H-to-2G mechanism is often used as a splitter, or as a quasi-edge shooter if the additional glider output is suppressed. It appears in many places in the glider gun collection, mainly for periods below 78 where syringes can't be used to build small true-period guns. The insertion reaction allows a glider to be placed 19 ticks in front of another glider on the same lane, or 30 ticks behind it. The 30-tick following distance can be reduced to 28 ticks if the perpendicular glider output is suppressed.
Besides an R-pentomino, the constellation of an eater 1 and a transparent beehive on the north can be activated by honey farm as well; this is the glider-liberating mechanism in p5 quinti-Snark.
