Patent pending

Last week I was in Detroit, Michigan for a family reunion, and while I was there I got to raid my grandmother's cedar chest for old treasures. This is an advertising brochure for the electric milk condenser my great-grandfather invented:

Ruff condensing evaporator

"This machine will evaporate any desired percentage of the water; so as to concentrate the milk three to one, or to any consistency that may be required... IT WILL PERFECTLY SUPERHEAT PLAIN CONDENSED MILK... Owing to the desirable temperature at which the Ruff Process condenses the milk, it adds to the digestibility and highly nourishing qualities of the product and makes it an ideal food for infants and invalids."

this post made me go google my grandfather's obscure papermaking patents. No delightful brochures, alas, but, incredibly, they are online.

See, my dad always had lots of Ideas but never did much with them -- much less obtain a patent. Our documentation consists purely of notes scrawled on bits of paper and the occasional paper napkin.

Interesting. Since I sit here searching patents for most of the day, I through in a basic search and it looks like he's not the only Ruff in the evaporation biz, nor is he the only John Ruff in the refrigeration art.

His patent didn't come up though, but the records from that era could be in better shape.

Is this still the way that evaporated milk is made today? (and why have I never questioned just how they make it before now? hmmm)

Also - would have loved the chance to have you sign my very old, very worn copy of "Fool On The Hill" as long as you were in Detroit...but I totally understand why you'd not let people know where you were going to be ;)

(it is great fun however to get a glimpse into the lives of favorite authors via LJ - you and John Crowley are always interesting to read)
