Rat lapping
Christopher Tidy
researching an old firm and found a reference in Google Books which
lists them as " PRODUCT — Precision Rat Lapping & Grinding". Is this
actually a process, or is it just an OCR error when it should say
"Part Lapping"?
Best wishes,

My dog laps up little baby rabbits and birds and things -- I think he'd
lap a rat right up.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.

Think microns, such as optical flats.
Maybe Chinese?

I did wonder if the word was flat. Here's the picture:

According to Google, it's "rat". But flat or part sounds more
sensible.

The more I think about it, the more I think it is "Flat". After all
"Fl" looks fairly close to "R" in some fonts. Thanks for the sensible
suggestion!

My conjecture would be that this is an OCR merger of F and l.
There is a machine in the shop like that for lapidary materials.
But the concept of seeing how rodents would do turning through a
maze built on a vibrating platform might have parallels to human
behavior in earthquakes.

404 error.

SWAG:
Perhaps scraping/lapping with a rat-tail file which was ground into a
scraper? <shrug>

The most common industrial venue for flat laps in my experience is in
optical shops,
so if your reference has any relevance to lens or glass working, that
would implicate
the process.

Likely an artifact of the OCR and a ligature of 'f' and 'l'. I
know that "fi" used to be commonly printed as a ligature (squished
together, so the dot of the 'i' merges with the ball on the top of the
loop of a lower-case 'f' in certain type faces.
Check this web page on the subject:

Enjoy,

I had an encounter with one of those last week. The Kido came into the
shop to do some speech homework with me for 15 minutes. I was eating
peanuts and tossing the shells into some kind of round military can
14"w X 15" h that is beside and under the cantilever of a smooth sided
work bench. After numerous tosses of shells I noticed a mouse in the
far side of the can cringing every time the shells where thrown at it
and staring at me. When I looked closer it's tail looked like it got
smashed in two places it the past.
The Kido said don't kill it, and since there where only peanut shells
in the trash can we drove it down to the end of the road about 1/4
mile. I dumped out the can and it ran down the hill.
24 hours later I tossed something in the can and there was the same
mouse staring back at me ! I was kinda wondering how it got into
there in the first place and now this.
Twin mice with a genetic mistake in their tails? Lost pets that
travel great distances to get back home? Time loops inside the
military can that was once on the USS Eldridge ?

For sure.
When I was 12, my dad bought a bike in an adjacent

I paid more careful attention to our route on car

Or an OCR spellcheck correction of 'frat lapping'?

1320-2000 feet isn't enough, hmmm.
I am new to this country stuff, kinda.
Cats and dogs must be really hard to get rid of. Just kidding pet
lovers.
I'd love to figure out these ^*#!$ flys. How do they propagate? Out
of the dirt? And they just stop for the winter. Soon as it gets warm
they come back to life.

Was the mouse wearing a little sombrero? ;-)

Friend had a sqirrel problem
He trapped squirrels by the dozen, relocating them several miles away
in a different semi-forested area. Got to thinking there's an awfull
lot of squirrels, and some of them are looking a bit familliar, so he
decided to spray paint a few tails. Within a few hours the little
beggars were back - so he decided to relocate them across the river,
some 7 miles away.
Painted tails were back within a day or two.
He figured he had 2 choices - baptize them or learn to live with them.
They are still there.
