  We generalize some properties related to Hilbert series and Lefschetz
properties of Milnor algebras of projective hypersurfaces with isolated
singularities to the more general case of an almost complete intersection ideal
$J$ of dimension one. When the saturation $I$ of $J$ is a complete
intersection, we get explicit formulas for a number of related invariants. New
examples of hypersurfaces $V:f=0$ in $P^n$ whose Jacobian ideal $J_f$ satisfies
this property and with explicit nontrivial Alexander polynomials are given in
any dimension. A Lefschetz type property for the graded quotient $I/J$ is
proved for $n=2$ and a counterexample due to A. Conca is given for such a
property when $n=3$. Two conjectures are also stated in the paper.
