Publication number: 20040154807Abstract: A downhole tool for connection in a work string to prevent premature activation of weight set tools on the work string. The tool has moveable pads which contact the tubing wall and thereby support the weight of the work string. The pads are activated by increasing fluid pressure in the annulus between the tool and tubing wall and deactivated by increasing fluid pressure through the central bore of the tool.Type: ApplicationFiled: March 19, 2004Publication date: August 12, 2004Inventors: Paul David Howlett, George Telfer

Publication number: 20040154808Abstract: A method of expanding tubing comprises the steps: providing a length of expandable tubing; locating an expansion tool, such as a cone, in the tubing; and applying impulses to the tool to drive the tool through the tubing and expand the tubing to a larger diameter. The tubing may be located downhole and may have a solid wall or a slotted wall.Type: ApplicationFiled: February 2, 2004Publication date: August 12, 2004Applicant: Weatherford/Lamb, Inc.Inventors: Neil Andrew Abercrombie Simpson, David H.

Publication number: 20040154809Abstract: A method and apparatus for advancing a rotating motorized downhole tool for operations in oil/gas wells. The apparatus is adapted for drilling and milling away of casing sections in the wells, as preparation for plugging the same. The appraratus includes a rotating tool and a driving motor indirectly suspended on coiled tubing. The apparatus also includes a carriage connected to the motor adapted to absorb torques that occur during use. The carriage is connected to the coiled tubing via a swivel coupling such that a tensile force on the coiled tubing provides an advancing force for the tool and motor.Type: ApplicationFiled: February 3, 2004Publication date: August 12, 2004Applicant: Bakke Technology ASInventor: Stig Bakke

Publication number: 20040154810Abstract: The invention concerns a method for enhancing resistance to external pressure to a pipe installed in a previously cased borehole, which offers a passage through its opening of reduced size. Said method consists in lowering the pipe in a first shape (2) whereof the dimensions are smaller than the reduced opening, in deforming it to convert it from the first shape in a second shape substantially cylindrical (3) having a dimension larger than the reduced opening and characterized by the expansion of the cylindrical pipe of the second form by displacement of an expansion mandrel through the pipe, the peripheral expansion lying between 2 and 10% of the value of the initial perimeter.Type: ApplicationFiled: May 15, 2003Publication date: August 12, 2004Inventor: Philippe Nobileau

Publication number: 20040154811Abstract: An aerator that allows the operator to make a turn with the machine while the tines are still in contact with the turf through the use of a differential shaft and brakes that enhance the maneuverability of the machine. The aerator is fitted with a mechanical gear type differential on an intermediate drive shaft that provides for automatic, separate and variable rotational motion of the individual halves of the tine shaft. This differential apparatus also provides constant and equal torque application to both sides of the tine wheel assembly simultaneously while the machine is operating. This insures that tine penetration into the turf is equal on both sides at all times. The tine shaft halves are designed and mounted in such manner as to allow each half (left and right sides) to be driven by separate chains from the differential shaft. This design results in a desired variation in the speed of rotation of the two halves that facilitates turning the unit.Type: ApplicationFiled: February 9, 2004Publication date: August 12, 2004Inventors: John B. Kinkead, Loren F. Hansen, Donavon D. Kotula, Thomas E. Isaman, Robert Brophy

Publication number: 20040154812Abstract: A stake and post driver having a sleeved construction topped with an expanded impact head is disclosed. The stake driver body is provided with a concavity for receiving an exposed end of the stake or post to be driven. The concavity is sized and shaped to receive the exposed end of the stake along a length sufficient to grip and support the stake or post during the entirety of the driving operation. The impact head is sized and configured to provide an enhanced “sweet spot” targeted by the user, thereby reducing the prior art requirement for essentially total accuracy in exactly delivering a significant driving impact from a manual driver such as a sledge hammer, mallet or other hand-held mechanical driving means to the typically small target of the exposed end of the stake or post to be driven.Type: ApplicationFiled: February 7, 2003Publication date: August 12, 2004Inventor: Jon Anthony McDonald

Publication number: 20040154814Abstract: A ground rod includes first and second ends connected by a shaft portion. The first end has an auger configuration permitting it to be drilled into the ground. The opposite end is adapted to attached to either an electric drill or an impact wrench. This drastically reduces the time required to drive the ground rod into the ground. In an alternate embodiment, the ground rod also adapted to attach to a handle which allows it to be manually inserted or removed from the ground.Type: ApplicationFiled: February 3, 2004Publication date: August 12, 2004Inventor: Bob Brennan

Publication number: 20040154815Abstract: The invention relates to an enhanced shielding arrangement. A shielding arrangement comprises a shielding can and a layered printed circuit board having electrical components and at least two ground potential layers. There are grounding connections between edges of the shielding can and at least one of the ground potential layers, and grounding connections between components inside the shielding can and at least one of the ground potential layers, so that the two grounding connections are connected to each other only through at least one of the ground potential layers for providing small loops.Type: ApplicationFiled: February 7, 2003Publication date: August 12, 2004Applicant: Nokia CorporationInventors: Karl-Erik Gustafsson, Jarmo Heinonen, Jyrki Koljonen, Jussi Salminen

Publication number: 20040154816Abstract: A modular conduit system for routing communications lines within the interior of a structure is disclosed. The conduit system comprises a modular housing for containing electrical wiring and other communications cables. In certain embodiments, the modular housing is configured to be installed along an edge of an inner wall covering. The modular housing includes ports for enabling outlets to be connected with the contained electrical wiring. The modular housing also includes a housing cover for enclosing the electrical wiring and communications cables within the housing. The housing cover is removably mounted with the modular housing. The housing cover can be removed in order to enable access to the electrical wiring and communications cables without interfering with or causing damage to the inner wall covering of the wall structure, for example.Type: ApplicationFiled: February 12, 2003Publication date: August 12, 2004Inventor: John Rainbolt
