This is a special case of a Herschel-to-Gn converter. The n=0 case is particularly interesting because H-to-G0s can occasionally be used to make compact glider guns, usually by simultaneously producing two of the signals in a pseudo period glider stream. An H-to-G0 is also the initial stage in the period-doubler toolkit used to synchronize all the gliders in some complex signal converters such as the stable line crosser.
Below is a stamp collection showing two composite H-to-G0 converters in the top row. On the second row are the four atomic converters known as of December 2018. An unlimited number of composite converters can be constructed using edge shooters or other conduits that include transparent output lanes, but most of these will be much larger than the three examples shown here. The composite NW31T120T290 allows the time between output gliders to be adjusted to any 170+8N offset.
