Actually, Gates calls them both. However, it looks like they differentiate pulleys from sprockets in the sense that sprockets transmit torque to the shaft it's on and pulleys don't (via bearings, aka idlers). So in Gates terminology, OP is looking for sprockets.
At any rate, check here:
http://www.royalsupply.com/store/pc/...kets-c1556.htm for HTD sprockets. However, as mentioned before, check out Vex and AndyMark, because they still carry HTD sprockets. SDP/SI also has HTD sprockets (SDP/SI calls them Metal Timing Pulleys, even shaft torque-transmitting ones). They carry both inch and metrique. I would, however, look into upgrading to the PowerGrip GT2/GT3 line of sprockets and belt.
