propeller pitch changing control

A pitch change control system (10) is operatively connected to the pitch change actuator piston (140) for selectively pressuring the pitch change actuator piston to effectuate a desired change in the pitch of the propeller blades (120).

A pitch change actuation system is disclosed for adjusting the pitch of a variable pitch propeller blade (120) operatively connected for pitch change to a pitch change actuator piston (140).

The stepping and the change of angle of attack are finished simultaneously and a new cutting sweep starts directly.

The press component may be a pitch changing apparatus.

When the joining sections are moved along the pitch change guide rails by the movement of the pitch change guide in the horizontal direction, the pitch of the substrate holding members is changed.

Speed control and pitch change methods, mechanical and electrical/electronic

The printing press (100) also includes a pitch changing device (10).
