Yes, I've got that Patent amongst a heap of others. Example 4 & 6 are a very slight re-working of the Wellington & Ward Borax MQ developer and a side step in the evolution of D76
This is the seminal "Anti Dichroic Fog" patent among other claims hidden in it. It was one of Henn's major works and is cited by A&T in the FDC. This is not the answer to the real problem, nor does it correctly give the "secret" ingredient of Microdol X, which is also used elsewhere from what I understand.
