The Francis- and Deriaz-type turbines (after the British-born American inventor James B. Francis and the Swiss engineer Paul Deriaz, respectively) use a "mixed flow," where the water enters radially inward and discharges axially.
It was first docked axially at the front of the station and then swung around to a perpendicular position by a mechanical arm, an adjustment that made the station L-shaped.
In mixed flow pumps, fluid is discharged both radially and axially into a volute-type casing.
The eyes of cyclostomes are degenerate structures, and the six axially derived muscles normally found associated with vertebrate eyes are diminished or absent.
The six axially derived eye muscles of fishes undergo only small modifications in tetrapods.
The unpaired dorsal and anal fins of teleosts (advanced bony fishes) have axially derived muscle sheets on either side, which, when contracted, may change their angle and even fold the fins.
It is occasionally necessary, however, to use some other axially symmetric surface on a lens or mirror, generally to correct a particular aberration.
The positive and negative elements must be axially separated to provide the lens with a useful amount of positive power.
A similar torque-to-thrust conversion can be obtained by either rotating an axially fixed screw to drive a rotationally fixed nut along the screw or by rotating an axially fixed nut to drive a rotationally fixed screw through the nut.
As was stated above, a type I superconductor in the form of a long, thin cylinder or ellipsoid remains superconducting at a fixed temperature as an axially oriented magnetic field is applied, provided the applied field does not exceed a critical value (Hc).
As a sample of this type, in the form of a long, thin cylinder or ellipsoid, is exposed to a decreasing magnetic field that is axially oriented with the sample, the increase of magnetization, instead of occurring suddenly at the critical field (Hc), sets in gradually.
