Abstract: An apparatus and method of milling a liner extending from a deviated wellbore into a main wellbore is disclosed. The liner is inserted through a window and cemented in place with the cement extending back into the main wellbore.  Mechanisms are provided on the liner to keep it away from the main wellbore casing wall to facilitate the proper operation of the washover tool. A top end taper is provided to help the washover tool reorient over the tubular liner if milling requires more than one trip into the well. A diverter is insertable prior to installation of the liner to assist in getting the liner to extend through a window. Upon milling through the liner, the washover tool straddles the diverter and latches into it to facilitate not only the removal of the diverter but also the entrapment of any debris created by the milling operation. Suitable sealing is provided with the diverter to keep the cement away from the latching mechanism during the cementing operation.

Granted: 2005-02-22
Abstract: A drill primarily intended for ejector drilling is made of one single piece, in order to avoid unsoundness that arises when welding and to avoid weld joint gaps in which a chip may easily get wedged. Moreover, the drill is provided with a turned-out chip space (13) in order to as far as possible avoid chip jamming. The inserts are preferably placed tangentially, which simplifies their mounting. In principle, the inserts are semi-circle formed and this simplifies both their pressing and the making of the insert pockets.

Granted: 2000-03-21
Abstract: A trailer mounted power swivel includes, in combination, a trailer and a power swivel unit.  The trailer is elongate and has ground engaging wheels supporting a cargo deck.  The cargo deck is divided lengthwise into a first section and a second section.  The power swivel unit is secured solely to the first section, thereby causing a load imbalance which renders the trailer unstable for highway travel.  This imbalance can be remedied by placing the second section of the cargo deck under load.  The second section of the cargo deck is adapted to carry a sufficient number of drill collars to counterbalance the weight of the power swivel unit until the stability of the trailer is restored.

Abstract: An improved pneumatic tool for the removal and application  of  tire  cross  chains  configured  having  a manually actuated valve connected at its inlet port to a compressed air source and at its outlet port to a pneumatic diaphragm motor for actuation of a diaphragm.  The control valve includes an air bleed port which allows air to escape through the valve when the trigger or other operating means is released deactivating the valve.  This feature allows an almost immediate recovery of the jaws to the open position. The pneumatic tool for the removal and application of tire cross chains also includes a fixed jaw support assembly having a base plate for attachment to the face of the pneumatic diaphragm motor, the fixed jaw support assembly having a pair of upright members attached to the base plate and  extending  perpendicularly  and  in  spaced  apart relationship to one another to accommodate the attachment of the fixed and the moveable jaws between the two upright members thereto.   This feature eliminates torque between the jaw assemblies and the pneumatic diaphragm motor when pressure is applied to the jaws.

Title: Method for shared memory management in network nodes
Inventor: MITRA DEBASIS
IPC: H04L12/56
Filed: 1997-08-18
Granted: 2001-12-25
Abstract: The invention concerns a method for a multi-port node having a shared buffer memory to provide enhanced data packet buffering capacity for established virtual circuits (VC's) through the node and one of its output ports while maintaining grades of service commitments. The method admits incoming data packets to a node for an established VC based on a determination of combination of factors including the effective memory requirements for each output port as VC's are created or terminated, the portions of buffer memory in use for conveying packets through the intended output port for the incoming packet, and the total amount of available shared memory in the node. Such determinations enable the node to better decide whether admitting the incoming packet would cause a disproportionate allocation of the shared memory for the intended output port. As a consequence, a relatively high packet buffering capacity can be achieved substantially without violating grades of service commitments.

Abstract: A remote database (110) is accessed from user terminals. A communication channel is established over the World Wide Web (101) and commands defining a user interface are returned from the database system  to the user terminals. The database system supplies an indication of quantifiable values to the user terminals inviting a user to select one of said values. An indication of a selected value is supplied to the database system resulting in an indication being returned of  available data mappings. A data mapping is selected by a user and an indication of a selected mapping is supplied to the database. In  response to this indication, an enquiry is made by activating database-specific instructions defined by Standard Query Language.

Abstract: An actuated air valve includes a valve body (12) in line with a flow passage  (14) for admitting a flow of fluid. A valve member (16) is pivotally mounted  about the centerline of the valve body and is pivoted between high flow and low flow positions.

Granted: 2003-11-18
Abstract: A high density perforating gun having a carrier housing tube and an interior charge holder tube through which are mounted zinc alloy shaped charges in a phased relationship between about 135 and 145 degrees. The 135 to 145 degree phased relationship provides for an 18 shot per foot perforating gun system.  The shaped charges of selected length are inserted into the carrier housing tube and held in place by fastener rings fitted to fastener ring slots. The nose ends of the shaped charges are fitted with ears to receive a detonating cord. This positions the primer cord in tension and generally coaxially with the carrier housing tube to prevent charge interference and assure sequential detonation.
