Glider-to-Herschel converter
A glider-to-Herschel converter (abbreviated to G-to-H) is a converter that takes glider(s) as input and produces a Herschel output, which can then be used by other conduits.
There are known glider syntheses for a clean B-heptomino that cost two gliders, and deleting the residual block consumes one more, resulting a total of 3 gliders for a Herschel synthesis recipe. Devices that convert one or two gliders into a Herschel with reasonably low recovery time have therefore been an ongoing topic of research for many years.
Several two-glider-to-Herschel converters were known as early as the mid-1990's, with no synchronization needed between the two input gliders, including Callahan G-to-H and unidirectional and 90-degree variants of the Herschel receiver.
Many examples including BFx59H injector and Jormungant's G-to-H consume two synchronized gliders. The following pattern was found by Emerson J. Perkins in April 2007.[1]

By recycling an output glider for cleanup, a periodic G-to-H (with a p8 bouncer) and the Silver G-to-H (with Herschel conduits) can be constructed from Callahan G-to-H. The search for stable 1G-to-H converters went on for many years. With modern catalyst-searching tools, new mechanisms like the syringe and the bronco were discovered, the former of which has found a variety of important applications in recent signal circuitry.
