Synchros do essentially the same thing. As the spinning gear approaches the new one, a cone gets pressed into a taper -- that friction gets the new gear spinning. When they are almost at the same speed, the dogs engage - the taperd bumps on the gear mate with the dogs on the hub.
So essentially the taper acts just like your clutch in neutral to spin e'm up.
With a syncronized transmission when you shift, you are actually moving a hub into then through the brass ring that's tapered, then it moves to the dogs on the new gear.
If you shift too fast the synchro doesn't have time to work.

Maybe you don't get what RRich is saying, maybe you do... Everyone thinks of things in different ways. Sometimes you can say something ten different ways and still not get your point across, then change your wording slightly and everything becomes clear for the person you are talking to...
Well here's my stab at it from another thread ((with pictures of synchros (blocking rings)...
syncros bad, hurt anything to drive it this way?
...oh yeah and a few tangents I added [img]images/graemlins/blush.gif[/img]
Everyone that has replied is trying to say the same thing... in their own way, with different points (that may or may not matter) just to add to your confusion.
