  • Patent number: 4394881
    Abstract: Well bore drilling apparatus has a steering tool operable to stabilize the drill string above the drill bit and to selectively cause a lateral force to be applied to the bit to deflect the drill in a selected direction. The apparatus includes master sensors, in the form of pistons, which sense the lateral force of the drill stem on the low side of the hole and apply fluid pressure to selected slave pistons which are circumferentially spaced above the drill bit to apply lateral thrust in the selected direction. The slave pistons are selected by valves in the apparatus which are opened or closed, as desired, either before running the tool into the well bore or by a wireline manipulator tool while the tool remains in the well bore.

  • Patent number: 4376495
    Abstract: A metering or dosing device connected to the neck of a squeeze-type tube or container, and capable of metering the amount of fluent material that can be discharged from the container after each removal of a closure cap screw-threaded, or otherwise secured, onto the neck of the container. The dose to be dispensed by the device is determined by the extent to which the cap is mounted on the container.

  • Patent number: 4368746
    Abstract: An applicator for applying cream to a person's lips including a tube for the cream having a deformable portion adapted to be squeezed to displace a quantity of cream into an applicator tip mounted on the tube. The tip includes a valve structure cooperable with the outlet of the tube to automatically close the outlet when a closure cap is applied over the applicator, to prevent undesired oozing. A spring engages the tip to open the valve after the cap is removed from the applicator.

  • Patent number: 4354559
    Abstract: A method and apparatus are disclosed for drilling a bore hole using a dual concentric drill pipe. Air is supplied through the outer pipe to the bit to cool the bit and jet cuttings upwardly in the bore hole to a suction inlet leading from the bore hole to the inner pipe. A negative pressure is applied to the inner pipe to bail the cuttings up the inner pipe. Makeup air flows down the annulus in the bore hole to the suction inlet and prevents upward movement of dust in the bore hole. A bore hole enlarging bit is disclosed and has expansible cutters which are expanded by hydraulic fluid pressure. In one form, the expansible cutters can also be retracted by hydraulic fluid pressure. The enlarging bit is employed to enlarge a pilot bore hole from a selected beginning location to the bottom of the pilot bore hole to form a blast chamber.

  • Patent number: 4354560
    Abstract: A rotary bore hole enlarging bit is connected to a rotary pipe string having a drilling fluid flow path and an actuator flow path. The bit comprises a body structure including inner and outer telescopic body sections, expansible and retractible arms carrying cutters on the outer body section and an expander on the inner body section engageable with the arms to expand the arms and cutters upon telescopic movement of body sections in one relative direction. A piston and cylinder is provided between the inner and outer body sections to secure relative telescopic movement between the body sections. A first passage is disposed in the body structure and expansible arms and cutters for conducting drilling fluid to the cutters from the drilling fluid flow path, there being a second passage in the body structure for conducting actuator fluid to the piston and cylinder from the actuator fluid flow path.

  • Patent number: 4351401
    Abstract: The invention relates to the design of earth bore-hole drill bits embodying shaped preformed cutters containing hard abrasive materials, such as diamonds, the cutters being mounted in companion preformed sockets in the hard metal bit matrix. The extent of penetration of the preformed cutters into the formation being drilled is controlled by providing surface set diamonds embedded in the matrix at or adjacent to its gage portion, the surface set diamonds projecting from the matrix to a much lesser extent than the preformed cutters. As a result, the surface set diamonds can penetrate into the formation only to the extent determined by engagement of the adjacent face of the matrix with the formation. Although the preformed cutters project from the matrix to a greater distance than the surface set diamonds, their extent of penetration into the formation is no greater than that of the surface set diamonds.

  • Patent number: 4340626
    Abstract: An elastomeric enclosure is initially inflated to a desired pressure by a gas having large molecules incapable of diffusing outwardly from the enclosure, except at a relatively slow rate. When the enclosure is surrounded by ambient air at atmospheric pressure, such air passes into the enclosures by reverse diffusion, thus extracting energy from the ambient sea of air to progressively increase the total pressure in the enclosure to a substantial extent over a period of several months, the pressure then decreasing very slowly over an extended period to its initial inflation pressure, such extended period being as much as about two years or more. This added energy may be used to perform useful work or used in various pneumatic devices to achieve essentially permanent inflation.

  • Patent number: 4329127
    Abstract: An in hole fluid motor for driving a drill bit utilizing the circulation of drilling fluid to drive the motor, having a sealed bearing assembly. The bearing assembly has a hollow, rotary drive shaft disposed within a tubular relatively stationary housing with radial bearings and thrust bearings disposed between the drive shaft and housing. Sealing structures are provided between the drive shaft and housing in axially spaced relation with the bearings disposed in a chamber between the sealing structures and lubricated by a lubricant confined by the sealing structures and pressurized through a diaphragm by the pressure of fluid externally of the housing in the drill hole. One of the sealing structures has a pair of clean fluid reservoirs separating the bearing lubricant from the drilling fluid in the housing by a pair of sealing devices, one between the bearing lubricant and a first of the clean fluid reservoirs and the other between the first and the second clean fluid reservoirs.

  • Patent number: 4310059
    Abstract: A composite drill collar for drilling bore holes in earth formations including a structural steel outer jacket having a lower end secured to a lower coupling connectable to a drill bit and an upper end secured to an upper coupling connectable to an adjacent drill collar thereabove. An annular heavy metal core of depleted uranium or sintered tungsten is disposed in the jacket and is held in compression therein as by shrink fitting it to the jacket. The structural steel jacket has a heavy wall thickness to carry the bending, torsion, compression, tension and impact loads encountered in the drilling operation, so that such loads are not carried through the core, which has the purpose of increasing the density and mass of the composite drill collar, lessening considerably the tendency for a deviated well bore to be produced.

  • Patent number: 4298077
    Abstract: An in-hole fluid motor has a stator connected with a fluid conduit and a rotor connected with a drive shaft for a bit to drill a bore hole as drilling fluid is circulated through the conduit and the stator, the fluid returning through the bore hole annulus to the top of the bore hole. A circulation valve between the stator and the fluid conduit is opened by the flow of fluid through the valve to by-pass the stator and allow flow of fluid into the annulus. The circulation valve is incorporated in a structure which allows the conduit to fill and dump during lowering in and removal from the fluid in the bore hole.

  • Patent number: 4295535
    Abstract: An in-hole motor drill assembly has the rotor of the motor connected to the drill bit and a housing connected to the running string, and normally disengaged torque transmitting members between said housing and said drill bit provide for engaging said bit and running string for mutual rotation, by pulling on the running string. The torque transmitting members are locked in engagement, enabling the tension on the drill pipe string to be relieved, and the bit can be rotated by rotation of the drill pipe string in either direction. The usual pick-up bearing between the housing and the shaft provides an abutment for a releasable thrust transmitting member which normally holds the clutch disengaged.
