Abstract: A method for operating a dual-clutch transmission includes, to resolve a respective tooth-on-tooth position between a toothing of a sliding sleeve and a toothing of a gear wheel during an engaging operation for the respective gear, a relative rotation between the toothing of the sliding sleeve and the toothing of the gear wheel is effected by a twisting torque which acts on the respective gear where the twisting torque is a same size for all of the plurality of gears.

Abstract: A bearing for vertical axles particular for use in goniometers comprises a non-displaceable member of an instrument on which a movable member is seated by means of a ball bearing. One of the two members possesses a cylindrical bush and the other one is provided with a journal projecting into said bush. The cylindrical region of the bush and of the journal is divided into three sections, which are sequentially arranged and in which the bush and the journal differ in their diameters. The difference of the diameters is larger in the second and smaller in the third section, if compared to the first section. The relation of the differences of diameters between the journal and the bush in the third section to the length of the third section is equal to or greater than the relation of the differences of diameters in the first section to the entire length of the cylindrical region.
