Abstract: A device for facilitating measuring and cutting conduit. The device includes two end plates sized and configured for receiving conduit while being provided with a surface for resisting rotation of the conduit as it resides upon and is supported by the end plates. A planar ruled member is attached to and supports both of the end plates preferably at a distance so that the device can be supported by the circumference of a standard five gallon bucket.

Abstract: A concealable flap actuated vortex generator for generating a vortex on a lifting surface assembly, and an improved aircraft flight lifting surface having such concealable flap actuated vortex generators. When the flap of the lifting surface assembly is in the nominal (non-extended or non-deflected) position, the vortex generator is unexposed. When the flap is actuated by a flap actuator, the flap is extended or deflected from the nominal position, thereby projecting or exposing the vortex generator into an operational position and enabling the generation of a vortex.
