New p2 'Blinker-Keeper' and H-to-G Converters

p1110+24N, N=1: Dave Greene, 13 November 2005
In November, David Bell found a way to recycle a glider from a 'blinker-keeper' mechanism discovered a couple of months previously, to produce a series of compact guns whose periods were multiples of 5, 6, 7, or 8. This improved a number of the glider guns in Jason Summers' extended gun collection.

Here is the original 'blinker-keeper' pattern on which the new guns were based: a blinker is reconstructed every 496 generations if it is found to be missing.

p496 bootstrapped pi-factory gun: Dave Greene, 20 Sep 2005
(can produce Herschel output via standard Fx176 conduit)
The blinker-keeper in turn was based on a pair of new Herschel conduits, which could also be used in building a series of compact guns, this time improving the size of glider guns in the main gun collection.
