Bell's inequality refuted without entanglement?

[ilyal]

Aspect's experiment that refutes Bell's inequality consists of measuring spins at various angles on two beams of entangled particles.
But apparently, according to "Feynman Lectures on Physics, Volt. III, page 6-14, table 6-2, Rye(&#934", measurements of spins on a single beam of particles yield the same results.
Do Feynman's results refute Bell's inequality as well?

Thanks.
