Granted: 2006-07-18
Abstract: An improved cage slip system is disclosed. The cage is constructed so that the cones which actuate the slips extend into the cage openings. The radial extension of the slips is limited so as to retain them if they are extended in an unsupported situation. The cones have a maximum outside dimension equal to the outside dimension of the cage so as to increase the rating of the slips by increasing the bearing area of the cones on the slips. The beneficial features of the cage design are retained while a greater degree of radial expansion of the slips is possible allowing minimization of tool inventory for situations where a lighter wall casing requires further slip extension.

Abstract: Packages having improved openable and resealable interlocking closures and methods and apparatus for making the same from a continuous web of film, the closure having male and female portions and being formed either in line with or transversely to the direction of film flow during package formation at line speed. A converter device adjunct to standard packaging apparatus forms a small amount of the running packaging film into a multilayer strip as an integral part of the film. The converter functions with both horizontal and vertical form/fill/seal wrapping machines and with overwrap packagers, and uses diverse packaging films and film laminations of which the substrates may be non-plastic. The packaging film is fed into the converter where the film is fanfolded to form a stack, the layers of which are heat sealed together forming a multilayered strip in plane with the film. The number of stack folds varies depending on the thermoforming properties and thickness of the particular film being used. The strip is abraded on one surface to selectively remove the thermoplastic coating, the film then passing into the package former where product wrapping takes place in packages having single or double overlap longitudinal package seals, and which places portions of the strip in stacked apposed position. The package ends are sealed and the package resealable locking closure is formed in the strip. The female portion of the locking closure is formed in the package face that includes the overlapped longitudinal package seal which includes multiples of the strip and optional additional layers. In another embodiment the strip is not abraded and the inner and outer parts of the resealable closure are separately formed before package formation takes place. Alternatively to form the strip, layering other than by fanfolding to form a stack may be utilized, as for example heat sealing a strip of heat sealable material to the packaging film. Also optionally formed in the resealable closure are hinges and reinforcing V-notches.

Abstract: A drill string section for use in making up a drill string for oil and gas drilling carries instrumentation for measurement while drilling and logging while drilling operations. The instrumentation includes a dynamic pressure device for measuring drill string bore pressure of incoming pressurized fluid and drill string annular pressure of returned pressurized fluid. The instrumentation is retrievable from the drill string when the drill string section is stuck or otherwise abandoned downhole. Said instrumentation can also be returned down hole and re-seated in instances where the drill string is re-commissioned for operation, or in instances wherein the tool needed replacement. The drill string section comprises a length of drill string pipe having a bore defined by an inner surface of a wall which has an outer surface. A cylindrical landing sleeve and a support for centering the sleeve in the pipe bore is provided. Communicating ports extend through the drill pipe wall from the outer pipe surface through one or more leg supports to an inside surface of the landing sleeve. The instrumentation is provided in an elongate cylindrical tool shell. The outer surface of the tool shell has spaced apart seals which engage the inside surface of the landing sleeve. The seals are located in the sleeve on either side of the communicating port(s), forming a leak tight annular region that eventually communicates through appropriate ports to a pressure transducer. The instrumentation in the tool shell has a first terminated port in the tool shell located between the seals which communicates with a pressure sensor used to measure drill string annular pressure. A second terminated port in the tool shell opens into the drill string bore and terminates at a second pressure sensor, permitting a pressure measurement of the drill string bore to be made independently of the said drill string annular pressure.
