The Soviet Patriotic War rule can be invoked on US and British units only if they are in a territory with a Soviet Industrial Center, correct?

Correct. The errata in the second edition rules specifies that the Soviet player can seize control of Allied units only if they are in Leningrad, Archangel, Stalingrad, or Moscow. Note that this does not mention any sea zones; Allied ships and subs are not subject to this rule and cannot be taken by the Soviet player.
