The power for driving the teeth ring can be got from the input shaft.

The counter-ring gear (20) is mounted so as to be independently rotatable vis-à-vis the input ring gear (19).

The input ring gear (19) and the counter-ring gear (20) engage simultaneously with the output gearwheel (27) and the at least one intermediate gearwheel.

An inlet rim of the downstream pipe converges radially inward to prevent backflow into the joint region.

Electrons generated where the beam from the exciting source (7) strikes the sample are emitted into 2π steradians towards an entrance annulus (8).

The power distribution system is driven by the input ring gear and distributes drive torque between the first and second output members.

A small fraction of these electrons enter the entrance annulus (8) and find themselves in an electric field which deflects them towards the mesh of the outer cone (6).

The power for driving the teeth ring can be got from the input shaft.

The input shaft is connected to the second ring gear.

The counter-ring gear (20) is mounted so as to be independently rotatable vis-à-vis the input ring gear (19).

The input member can be selectively engaged to the ring gear.

The input shaft has a pinion that is meshingly engaged to the ring gear.

A power transmission device includes a rotatable input shaft, a rotatable output shaft and a ring gear fixed for rotation with the input shaft.

The planet carrier of said input planetary gear set (10) is coupled to the ring gear of said input planetary gear set (10) via an overrunning clutch (16).

The input ring gear (19) and the counter-ring gear (20) engage simultaneously with the output gearwheel (27) and the at least one intermediate gearwheel.
