When the first planar motor is brought closer to the center planar motor, the drive mechanism moves so that the moving section moves away from the center planar motor.

The hull is symmetrical along a central horizontal plane and the fairing may be positioned along the central horizontal plane.

At zero joint angle the balls (40) are positioned in a ball center plane and define a ball center radius (BCR) in the ball center plane.

The apparatus is substantially balanced about a vertical central plane.

The core engine cowl and fan cowl are disposed around a horizontal central plane.

A modular server system (100) includes a midplane (170) having a system management bus and a plurality of blade interfaces on the midplane.

A plane (PSR 20) through the sealing region is spaced from a central vertical plane (Pc20) through the package (20).

A spring extends across the central plane and interconnects the respective pinch arms so as to urge both pinch arms towards the central plane.

The fan drive gear system has a centerplane (540).

The contact pins (2) are disposed along one whole edge margin of the centre plane in a terminal field (8A) which can be reached from one side of the centre plane.

The undulating surface also causes the slits to form a plurality of openings which are generally perpendicular to the central plane of the film.

In addition, due to the undulating nature of the surface of the film, the apertures so created reside in, above and below the central plane of the film layer.

A cigar-shaped fuselage is arranged on the central wing.

A central axis of the inlets (210, 220, 230) is substantially perpendicular to a central plane of the outlets (152, 162, 172).

No doubt the central plan was full of defects, but the Soviet economy did fine despite the central plan.
