Paul Desmond is using emebellisments that are often called turns. Basically this is a triplet (or something similar) on the first of a pair of 1/8 notes. It comprises of the note, then the note above and quickly back to the note:
So, e.g. instead of just a plain run G - F - E - D - C, it might go GAG - F - E - D - C.
He is also using some double time passages. This means that you establish a some typical strings of 1/8 note phrases which is common in jazz, but then suddenly though in some 1/16 note passages.
