Abstract
We consider the general problem of motion of a rigid body about a fixed point under the action of an axisymmetric combination of potential and gyroscopic forces. We introduce two new cases of this problem which are integrable on the zero level of the cyclic integral. The new cases are combined generalizations of several previously known ones, namely those of Kovalevskaya, Yehia, Sokolov, Yehia and Bedweihi and Goriatchev, by the introduction of additional parameters to the structure of each.
