I love those kinds of patents!  A friend's patent attorney was telling me
that one way to help your patent app glide through is to write it that way.
The examiners love to see practical details and test data.
Much better to say "a preferred embodiment uses a 1/4"-20 bolt 3" long
tightened to 50 inch pounds" rather than "a preferred embodiment uses a
threaded fastener".  Save the generic "fastener" for the claims.

 His comment was that once the patent issues, nobody can duplicate (legally)
what you describe in your disclosure (assuming the claims were written to
cover it), so why be coy and vague. He also said that a good disclosure
makes your patent more likely to be cited by others as prior art, and hence,
less likely to have those subsequent patents have claims that overlap yours.

Now, I will confess that I have met other patent attorneys who like vague
and coy, because that confuses people reading it, and you might be able to
negotiate a better deal in a cross-licensing sort of situation. Naturally,
of course, those attorneys assume you'll be hiring THEM to do that
