  The orbits of visual binary systems still attract many of the working groups
in astronomy. These orbits are the most important and reliable source of the
stellar masse. In the present paper, we are going to compute orbits and
dynamical masses of some visual binaries using an independent code. We used
Kowalsky method to compute the geometrical elements. The dynamical elements
(the period and the time of the periastron passage) are computed by
implementing the double areal constant. We used the developed code to calculate
the orbits for the four visual binaries, WDS J02262+3428, WDS J14310-0548, WDS
J17466-0354, and WDS J12422+2622. We introduced a new orbit of the neglected
visual binary WDS J17466-0354 and modified orbits for the rest three binaries.
Using the Gaia DR2 parallaxes we computed the total masses of the systems.
Comparing the adopted total masses with those derived from the spectral type
relation revealed good agreement.
