Title: Pressure-actuated perforation with automatic fluid circulation for immediate production and removal of debris
Inventor: HAYES KIRBY
IPC: E21B43/119
Filed: 2004-11-18
Abstract: Openings are created between a wellbore and a formation by firing a perforating gun adjacent to a zone in the formation and the production fluids are produced along with any formation debris. A tubing string extending to the formation is pressurized to actuate the perforating gun and simultaneously t o actuate a downhole injection port. Substantially immediately thereafter flui ds are injected into the wellbore near the openings and circulated to the surface f or the removal of debris and the production of the formation fluids. An optional an d uphole injection port can be used to adjust the hydrostatic head above the perforating gun with the removal or addition of fluid prior to actuation. Th e tubing string extends sufficiently above the wellbore at surface to enable lowering of the downhole injection port below the openings during fluid circulation for enhanced removal of debris.

Patent CA-2502540-A1 (CA)
Inventor: PELED ERAN
IPC: H04J3/06
Filed: 2003-10-14
Abstract: The invention enables the use of the asynchronous Ethernet MAN (C) as if it was a regular fiber optic line, while eliminating the uncertainties of it's cloud environment. The invention provides a new method for synchronizing transmissions of real time synchronous data packets over an asynchronous network between two terminal nodes (A1) and (A2). The synchronization procedure is implemented within intermediating communication devices, which connect between the terminal nodes TDM equipment and the asynchronous network (C). Each communication device comprises local clocks, which are activated by a Stratum 2/3/3e/4/4e pulse generator. The local clocks synchronization is based on the transmission of the timestamp packets through an asynchronous network. Based on the references, an internal digital PLL enable, attenuating the jitter/wander in data transmission signal in accordance to Stratum 2/3/3e/4/4e accuracy standards. The DPLL data result is then processed to be used by the local clock of the receiving terminal.

Abstract: The present invention provides a unique system and method that facilitates incrementally updating spam filters in near real time or real time. Incremental updates can be generated in part by difference learning. Difference learning involves training a new spam filter based on new data and then looking for the differences between the new spam filter and the existing spam filter. Differences can be determined at least in part by comparing the absolute values of parameter changes (weight changes of a feature between the two filters). Other factors such as frequency of parameters can be employed as well. In addition, available updates with respect to particular features or messages can be looked up using one or more lookup tables or databases. When incremental and/or feature-specific updates are available, they can be downloaded such as by a client for example. Incremental updates can be automatically provided or can be provided by request according to client or server preferences.

Abstract: A frame for automatic umbrella style canopy tents and a tent including the frame are disclosed. In the tent frame, the spreaders, which expand or collapse the upper ribs in radial directions, are configured as extendible members, thus reliably locking the tent frame in an expanded state and securely maintaining a pitched state of the tent. In the tent frame of the present invention, each of the spreaders includes a first spreader part coupled to the upper rib and a second spreader part which is coupled to a spreader holder and into which the first spreader part is inserted such that the first spreader part is extendible, with a spring installed in the second spreader part and causing the first spreader part to be extended. A repulsive force, which acts both on the first and on the second spreader parts due to the restoring force of the spring when the tent is pitched, restricts the movement of the spreader holder, thus securely maintaining a locked state of the tent frame, so that the pitched tent can be prevented from being undesirably closed.
