  $GL_h(n) \times GL_{h'}(m)$-covariant (hh')-bosonic (or (hh')-fermionic)
algebras ${\cal A}_{hh'\pm}(n,m)$ are built in terms of the corresponding R_h
and $R_{h'}$-matrices by contracting the $GL_q(n) \times
GL_{q^{\pm1}}(m)$-covariant q-bosonic (or q-fermionic) algebras ${\cal
A}^{(\alpha)}_{q\pm}(n,m)$, $\alpha = 1, 2$. When using a basis of ${\cal
A}^{(\alpha)}_{q\pm}(n,m)$ wherein the annihilation operators are
contragredient to the creation ones, this contraction procedure can be carried
out for any n, m values. When employing instead a basis wherein the
annihilation operators, as the creation ones, are irreducible tensor operators
with respect to the dual quantum algebra $U_q(gl(n)) \otimes
U_{q^{\pm1}}(gl(m))$, a contraction limit only exists for $n, m \in \{1, 2, 4,
6, ...\}$. For n=2, m=1, and n=m=2, the resulting relations can be expressed in
terms of coupled (anti)commutators (as in the classical case), by using
$U_h(sl(2))$ (instead of sl(2)) Clebsch-Gordan coefficients. Some U_h(sl(2))
rank-1/2 irreducible tensor operators, recently constructed by Aizawa, are
shown to provide a realization of ${\cal A}_{h\pm}(2,1)$.
