    摘要： The proposed hydro-mechanical slot perforator for well drilling is a device designed for opening productive formations in at least two projections forming high quality slots. The perforator includes a casing, housing a piston-pusher, and a cutting assembly, located below the piston-pusher, including extendable cutting tools and a mechanism for extending thereof, formed as a double-arm (lower and upper) lever (or a balance beam), whose arms hold the cutting tools. A deflecting wedge is mounted on a mobile shaft under the lever. The shaft rotates when the lower arm interacts with the wedge, while the piston-pusher moves down. The piston-pusher is designed as a wedge-piston acting on the upper arm, extending the top cutting tools out, resulting in the wedge-piston and the deflecting wedge creating oppositely directed forces acting simultaneously upon the upper and lower arms. Another embodiment is proposed where an augmented cutting assembly includes more than two cutting tools.

    摘要： A device for simultaneously forming multiple notches in opposing surfaces of a hollow workpiece in a single action. The device includes a first die and a first punch that is fixed relative to the first die. A second die and a second punch are fixed relative to each other and movable relative to the first punch and first die. In response to movement of the second die and second punch, the first die cooperates with the second punch to form a first notch in the first surface and the first punch cooperates with the second die to form a second notch in the second surface.

    摘要： A lifter bore groover tool having a housing in an essentially rectilinear configuration which has an upper wall and a lower wall and a plurality of side walls. The side walls include a cutting wall and another wall and facing walls there between. A bore is formed in the housing adjacent to the cutting wall. A long cylindrical chamber beneath the bore is in communication with a guide slot extending through the cutting wall. A cylindrical cutting block is axially reciprocable within the long cylindrical chamber. A cutting tool is removably supported in the cutting block extending laterally through the guide slot for contacting the surface of the bore to be grooved. The cutting block and cutting tool are axially adjustable. A bolt is received within the bore. The bolt has an upper end with a head for rotation by the user. The bolt has a lower end rotatably coupled with respect to the cutting block whereby rotation of the bolt will axially shift the cutting block and tool to cut an axial groove in a bore upon rotation of the bolt by the user.
