B. 18, beat 3: vii half-diminished 4/3 (2nd inversion) of E-flat acting more as a secondary dominant to II or G. The A-flat makes this a secondary dominant function chord rather than a simple vi4/3....though it's more or less acting like a vi 4/3 leading to ii.
B. 19, beats 1,2: II (or G) 4-3 suspension (C resolves on beat 3 to B natural); which (on beat three) this chord then acts as a V of V (C major in F).
Play through it on the piano, and you'll hear this little nugget--pretty cool stuff. Thanks, Bach. Good borrowing, Thom Stevens.
EDIT! I had another look and have changed my answer a little. Interesting (non-textbook) situation. It involves a little bit of modal mixture (borrowing the A-flat from the parallel minor (f minor) and secondary dominants.
