The total polarized proton-deuteron cross section for the case of vector polarization of the incident proton $P_y$ and tenzor polarization $P_{xz}$ of the deuteron target provides a null test for the time-invariance violating but P-parity conserving effects [1]. The dedicated experiment is planned by the PAX collaboration at COSY [2] at proton beam energies 135 MeV. Besides of the net T-invariance violating effects it is necessary to study possible falsh-effects caused by pure strong and Coulomb interaction due to non-ideal conditions of the experiment. For this aim one has to know angular dependence of the spin-correlation parameters $C_{y,y}$, $C_{xz,y}$ for elastic scattering in forward hemisphere and the total polarized cross sections $\sigma_1$ and $\sigma_3$ (for definitions see Ref. [3]). However, experimental data on these observables at this energy are rather poor. In present work we calculate these observables using the formalism of the pd-elastic scattering recently developed in Ref. [4]. The formalism includes full spin dependence of elementary pN-amplitudes and S- and D-components of the deuteron wave function. We developed the formalism to calculate spin-correlation and spin-transfer parameters and account for Colomb effects. Furthermore, we properly modify the formalism of Ref.[4] to provide comparison with the existing experimental data [5,6] presented in different reference frame. The results of our calculations for unpolarized differential cross section, vector $A_y$ and tenzor $A_{ij}$ analyzing powers, spin correlations parameters C_{i,j}, C_{ij,k} and spin-transfer coefficients $K_j^{i'}$ at 135 MeV and 250 MeV are in reasonable agreement with the available experimental data at small scattering angles ($<30 ^o$) and/or Faddeev calculations [5,6]. We found that Coulomb effects improve agreement with the data at this energies at small angles. The total hadronic polarized cross sections $\sigma_1$ and $\sigma_3$ are calculated using the optical theorem, whereas Coulomb effects are taken into account in the line of Ref. 7]. [1] H.E.
