A new class of CTPS's is constructed some of which are associated with certain modular invariants, thereby establishing the expected existence of the corresponding two-dimensional theories.14 pages; references added and minor improvementsOperator AlgebrasHigh Energy Physics - TheoryMathematical Physics81T05; 81T40; 46L37text
