Abstract: Systems and methods presented herein provide for cutting in a borehole or casing. A cutting device can include a first arm having a cutting blade, wherein the cutting blade has side cutting teeth and an axis of rotation that is substantially at a right angle with respect to an axis of the tool body. The cutting device can also include a second arm with a bumper. The first and second arms articulate away from the elongate body in different directions to reduce vibrations while cutting. A control device can automate the cut based on hydraulic pressure measurements. Additionally, the cutting device can also be extended or rotated on a rotary index. The cutting device can rotate around a J slot, in an example.

Abstract: A linear tire and wheel assembly comprising a hub having spaced flanges on which are mounted an inner tube surrounded by a jacket over which a tire casing is mounted so that inflation of the inner tube results in the formation of a tire mounted on said hub. The jacket is made of flexible material which takes a predetermined shape when enlarged by the inflation of the inner tube. Air under pressure is supplied through one of the flanges.
