Title: Method for selecting relevant campaign messages for transmission to recipients
Inventor: DICKER RUSSELL
IPC: G06Q30/02
Filed: 2004-03-10
Abstract: The present invention is directed to automating the sending of campaign messages (260) in computing environments. Campaign scores (280) are determined for messaging campaigns (260) and eligible recipients are assigned to campaigns with a higher score. More specifically, eligible recipients are assigned to a particular messaging campaign if the campaign is the "best"  campaign for each eligible recipient based on the campaign score.  Additionally, a portion of the eligible recipients are reserved as a control group for each campaign. After campaign messages have been sent out to assigned recipients, the behavior of the recipients who received campaign messages and the behavior of the control group members are differentiated to update the campaign's score (280). Continually updating campaign scores (280) makes it possible to continually update which campaign is best for a particular recipient.

Title: Instrumented plunger for an oil or gas well
Inventor: CHISHOLM CHRISTIAN
IPC: E21B47/00
Filed: 2005-09-14
Abstract: In one embodiment of the present invention, a plunger for use in a plunger lift system of an oil or natural gas well is described. The plunger includes one or more sensor assemblies, each including one or more sensors for measuring various physical and operational conditions during the operation of the well. The data acquired from the sensors is stored in memory within the sensor assemblies and downloaded to the plunger lift system controller when the plunger is located in the catch/lubricator. The data can then be analyzed by the controller or other computer to vary the well's operating parameters to maximize the well's operating efficiency and the data can be used in reservoir management, such as transient testing, reservoir modeling and interference testing.

Abstract: The present invention is directed to an improved reaction process that allows for the achievement of excellent NF3 production yields, while minimizing the amount of unreacted fluorine exiting with the process gases and minimizing the amount of liquid melt waste (HF/NH3) produced by the process. The basic NF3 process resides in reacting F2 with an ammonium ion source, e.g., ammonium acid fluoride, under conditions for forming NF3. The improvement in the process comprises: introducing F2 and said ammonium ion source cocurrently and downflow through a packed column or monolith column at a first temperature; reacting said F2 and ammonium ion source in said column; and, removing a mixture of NF3 and byproducts from said column at a second temperature higher than said first temperature.

Title: Flow control for irrigation machines
Inventor: CHOAT WAYNE D
IPC: A01G25/09
Filed: 2004-04-28
Abstract: This invention relates to a fluid flow control method that enables a self-propelled irrigation machine to apply varying amounts of fluid as might be required to suitably treat the surface area affected by each of the individual fluid application devices thereon. The control method regulates the total volume of fluid emitted by each application device to a predetermined value as it responds to a suitable control signal to permit or prevent fluid flow. This fluid flow control method involves time-based rapid cycling of the flow control apparatus to provide continuously variable fluid flow as is required to meet the desired average output of each emitting device as the flow requirement varies from time to time as needed to produce a selected, pre-determined application rate throughout the treated surface area.

Title: Whipstock assembly for a sleeved casing
Inventor: COON ROBERT JOE
IPC: E21B7/08
Filed: 1996-01-10
Abstract: A casing is provided with a sealable shifting sleeve. A whipstock is insertable into the casing and may be supported off of the casing in a predetermined location so that it is oriented toward an open window in the casing when the shifting sleeve is selectively moved upwardly. By presenting an open window for the whipstock oriented toward the window, a drillbit may be lowered through the casing to interact with the whipstock to immediately begin the drilling of the deviated wellbore. The drillbit cuts through any cement, if present, and into the formation. A bore is presented in the whipstock to allow production from pay zones below the whipstock while it is in place. Should it become necessary, the sliding sleeve may be subsequently closed to isolate the deviated wellbore which has been drilled with the whipstock through the open window.

Title: Authenticity verification methods, products and apparatuses
Inventor: COWBURN RUSSELL PAUL
IPC: G06V10/44
Filed: 2005-03-09
Abstract: A method and apparatus for determining a digital signature from an article made of paper, cardboard, plastic or many other material types. A coherent light source directs a beam to illuminate the article and a detector arrangement collects data points from light scattered from many different parts of the article to collect a large number of independent data points, typically 500 or more. By collecting a large number of independent signal contributions specific to many different parts of the article, a digital signature can be computed that is unique to the area of the article that has been scanned. This measurement can be repeated whenever required to test authenticity of the article. Using this method, it has been discovered that it is essentially pointless to go to the effort and expense of making specially prepared tokens, since unique characteristics are measurable a in a straightforward manner from a wide variety of every day articles.
