Does anyone know how Jimmy Page gets this pulsating pitch-shifting sound all the way up to the song-tempo change? Thanks much.

How does he get the shift to pitch right before the tempo change?

A picture is worth a thousand words; about 4:15 the transition starts. He’s just working the fretboard and bending notes.

It looks like he's bar-cord-sliding down the neck while playing the bow:

Late one rainy night driving through the hills of Pennsylvania I stuck in a Zeppelin CD I had never listened to and heard this.
I consider it the ultimate example of Page's bow period.

Page and Bonham must have both made deals with the devil. Forever's the pity Bonham's deal was so Draconian.

On the original it's layered with at least 3 guitars so it seems more dramatic.
