Patent CA-2221406-C (CA)
Inventor: GARCIA-SOULE VIRGILIO
IPC: E21B34/04
Filed: 1997-11-18
Granted: 2004-01-20
Abstract: A retainer valve provides increased safety in wellsite operations. In a preferred embodiment, operation of the retainer valve may be responsive to control line pressure or to tubing pressure. The retainer valve response is controlled by several factors, among which are relative tubing and balance line pressures, and axial positions of a number of pistons relative to a tubular J-slot member. If the control and balance lines are disconnected, or otherwise unavailable for operation of the valve, it may still be operated by manipulation of the tubing pressure at the earth's surface. Thus, the valve may be opened in emergency situations in which the control and balance lines are unavailable, but operation of the valve is still needed in order to safely relieve trapped pressure in the tubing string and/or to kill the well, unlatch a subsea test tree, etc. The retainer valve is also useful as a lubricator valve.

Title: An improved messaging platform process
Inventor: JANOW RICHARD H
IPC: H04M3/53
Filed: 1997-11-24
Granted: 2002-08-13
Abstract: Numerous benefits are realized by allowing messaging platforms to receive and act on information packages that include one or more Execution Instruction Sets (EISs), where the EIS is executed as specified. Execution of the included EISs provides vastly enhanced capabilities to the messaging platform, such as controlling when an EIS is executed, from where necessary data is obtained for the execution of the EIS, what kinds of executions are permitted, who will be the recipients of the content portion of platform, what that contentwill be, etc. Increasing the interaction complexity a step further, the EIS permits creation of an interactive session with the recipient that makes the message more effective. A still additional capability is the establishment of a communicationpath from the messaging platform. This may be in the form of a message that is sent by the messaging platform, or a connection that is established between the recipient and some other party.

Title: System and method for electrosurgical cutting and ablation
Inventor: THAPLIYAL HIRA V
IPC: A61B17/00
Filed: 1996-11-19
Granted: 2000-02-15
Abstract: An electrosurgical probe (10) comprises a shaft (13) having an electrode array (58) at its distal end and a connector (19) at its proximal end for coupling the electrode array to a high frequency power supply (28). The shaft includes a return electrode (56) recessed from its distal end and enclosed within an insulating jacket (18). The return electrode defines an inner passage (83) electrically connected to both the return electrode and the electrode array for passage of an electrically conducting liquid (50). By applying high frequency voltage to the electrode array and the return electrode, the electrically conducting liquid generates a current flow path between the return electrode and the electrode array so that target tissue may be cut or ablated. The probe is particularly useful in dry environments, such as the mouth or abdominal cavity, because the electrically conducting liquid provides the necessary return current path between the active and return electrodes.

Granted: 2003-04-22
Abstract: A two-step process for clearing unexploded ordnance ("UXO") from the ground. First a high power electromagnetic transmitter sweeps the ground area to be decommissioned. Secondly a lower-power time-domain electromagnetic transmitter or metal detector sweeps the same area to locate UXO. The high power transmitter employs a waveform of having the same frequency and pulse duration as that of the metal detector but does so with at least twice the power. Firstly, when the higher power waveform is applied to the ground, UXO which does not trigger and detonate or "function" is proved as non- functioning at subsequent and lower detection power. Subsequently, the ground area can then be safely scanned by human personnel with impunity, applying the more accurate, lower power metal detector. The detected locations of unexploded ordnance are recorded for subsequent manual removal.

Title: Sea chest covers
Inventor: PASTORE JOSEPH
IPC: B63B13/02
Filed: 1998-06-18
Granted: 2000-06-06
Abstract: A sea chest cover for providing access to the sea chest of a ship. The sea chest cover is fabricated essentially entirely of one or more viscoelastic materials, preferably either polyethylene or polyurethane. Fabrication of the sea chest cover from a viscoelastic material reduces or eliminates corrosion and erosion problems. It also minimizes marine organism and ice build-up. The result is a reduction in the expense associated with maintaining such covers. The fabrication of the sea chest cover essentially entirely of viscoelastic materials minimizes the weight of such components, thereby making handling and maintenance easier. The sea chest cover is either pre-formed to a shape conforming with the shape of the ship's hull in the area where the sea chest is located, or it is sufficiently flexible to be placed into such conformance. The sea chest cover of the present invention may be formed as a unitary piece or as a plurality of removably connectable parts.

Granted: 2002-03-26
Abstract: A laser tracking system steers a beam of laser energy which is dithered in two directions to scan the surface of a moving object.  A laser energy detector detects laser energy reflected from the target.   Reflected energy is filtered to distinguish   dither   frequencies   for   signals   in   both directions,  which  signals  are  independently  analyzed  to determine the location of the target in relation to the laser beam.   A bias signal is generated which causes the beam of laser energy to be steered toward a surface radius  to be steered toward a surface with the largest compound curvature within the trackers'  field-of-regard,  to the target,  to the tracked  location  on-target,  or  modified  signals  steer  a portion of the beam to an optimum track location on target while  offsetting  most  of  the  beam's  energy  to  a  second engagement location on target.  Also, a track testing system is capable of monitoring a laser beam focused on a missile and determining the effective laser engagement on a spinning target.
