Query: Gravitational Bending of Light with Frequency Shifts   Non-static gravitational fields generally introduce frequency shifts when
bending light. In this paper, I discuss the frequency shifts induced in the
bending of light by moving masses. As examples, I treat the recently discovered
high-velocity pulsar PSR 2224+65 and a typical Einstein ring.
