Title: Erosion resistant aperture for a downhole valve or ported flow control tool
Inventor: RUSSELL RONNIE D
IPC: E21B41/00
Filed: 2005-05-25
Granted: 2009-12-15
Abstract: An aperture design minimizes erosion on the surrounding casing and to the aperture itself and is particularly effective in fluid injection wells where large volumes of fluids over a long period of time with entrained solids are expected to be pumped through. The preferred design is an elongated shape with a flaring wider in the downhole direction. The downhole end of the opening features an exit that flares in the downhole direction with multiple slopes with an arc transition. Other options for the opening configuration are envisioned.

Abstract: A system and method for handling e-mail address mismatches between the address contained within a user's certificate or certificate chain, and the account address actually being used is disclosed. In order to resolve address mismatches a canonical or generic domain name or user name may, for example, be used as a lifelong address of a user that is contained in the user's certificate. Upon detection of an address mismatch, the system and method disclosed herein may automatically re-check the certificate or search for a certificate containing the canonical or generic domain name and/or user name to attempt to resolve the mismatch. This mismatch resolution is preferably transparent to the user and occurs automatically. The canonical or generic domain and/or user names that are available to the device may be typically controlled by IT policy that is in place on the system for the device. While this system is suitable for any type of electronic messaging system, it has particular applicability to systems that use mobile wireless communication devices with electronic messaging capability.

Abstract: The invention concerns a hot air device for thermowelding membranes to surfaces. It includes an air inlet, a casing in fluid communication therewith, a combustion chamber mounted within the casing and spaced apart therefrom. The chamber has perforations allowing air to flow therein. The perforations allow some air to flow into the upstream section of the chamber producing an air-fuel mixture, and let the remaining air into the downstream section, thus shortening the flame within the chamber and producing hot air. The device includes an outlet portion for expelling hot air and not allowing a flame out therefrom, and a blower to force airflow from the air inlet through the chamber and out from the nozzle. The chamber may be pyramid or cone shaped and have a deflector to help direct air into the upstream section.

Abstract: The use of the cementitious ash in building products as total or partial replacement for Portland cement results in reduced carbon dioxide emissions that would otherwise result form the manufacture of Portland cement. In addition to avoided carbon dioxide emissions from calcining of limestone to make Portland cement and the burning of fossil fuels to provide the energy needed to make Portland cement, use of the sorbent components tends to increase the efficiency of energy production from burning of coal, further reducing greenhouse emissions from the burning of fossil fuel to produce energy.

Abstract: A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.

Abstract: The present invention relates to the handing off without packet loss, from a mobile device traveling from a current point of attachment to a new point of attachment, by providing a copy and forward module in association with the current point of attachment. The copy and forward module copies and stores packets that are being transmitted to a mobile node while the mobile node is in transition from the current point of attachment to the new point of attachment. The copy and forward module maintains a list of addresses as the last known contact addresses of the mobile node, and the mobile node's initial copy request contains an initial contact address of the mobile node. Subsequent copy requests are used to add or delete addresses to the list, and carry a per-address flag to indicate whether the address is to be added or deleted from the list.
