Abstract: APPARATUS FOR CHEMICAL CUTTING     ABSTRACT OF THE DISCLOSURE     A method and apparatus for cutting tubing suspended in a borehole.  An elongated tubular assembly is provided for suspension in and securement within a wellbore for the chemical cutting of the tubing therein through the discharge of high velocity streams of a highly reactive, incendiary chemical fluid.  The apparatus includes the storage of a halogen flouride, or the like, disposed within a chemical module inter-mediately disposed of propellant and slip assembly modules and a discharge head assembly.  The propellant module is constructed with a chamber containing active burning ignition powder for igniting a slow burning propellant for the generation of gas to pressurize the chamber and cause a linear actuation of the slip assembly responsive thereto for the deployment of a cylindrically segmented slip array to securely engage the adjacent tubing and anchor the apparatus therein.  The generation of the pressurizing gas also imparts a movement of the in-cendiary fluid through a catalyst chamber for causing the fluid to react and discharge through the discharge head assembly for the cutting of the adjacent tubing.  The slip assembly is constructed with a dual taper, gripping teeth configuration for matingly engaging two discrete tubing dia-meters, therein facilitating interchangeable use within conduit of different sizes.  The assembly also includes a pair of rupture diaphragms enclosing the incendiary fluid, which rupture to a substantially full flow opening at a preselected breakthrough pressure to facilitate effective and safe oper-ation of the present invention.

Abstract: ABSTRACT OF THE DISCLOSURE           A sliding plunger with rack-shaped opposed sides controls opposite rotations of a pair of rotating sector gears with which integrally rotate two arms extending towards the conveying units.  Connecting rods are disposed between the arms and conveying units to transform the rotary motion of the arms into a corresponding translatory motion of the conveying units in opposite senses along fixed rectilinear guides transversally disposed with respect to the carton support base.  The sliding of the rack plunger can be controlled by a pneumatic cylinder or by a hand-control lever.  There can be provided adjustable means for limiting the sliding plunger stroke in the sense correspond-ing to the mutual removal of the conveying units and resilient thrust means acting on the plunger in the opposite sense.

Restriction of the fluid flow to any desired extent is accomplished by command signals directed by a control computer to a valve that preferably is of the type actu-able by a torque motor.  The command signals produced by the computer are based upon a correlation of data supplied by a computer program with data supplied by a monitor of the positions of the driven member along its path of travel.  Precise control of the speeds, accelerations and positions of the driven member are realized.
