Title: Multi-stage regeneration of a particulate filter
Inventor: XU LIFENG
IPC: F01N3/023
Filed: 2008-08-14
Abstract: A method of regenerating a particulate filter (fig 1; 70), in an apparatus comprising an internal combustion engine (fig 1; 10) and a catalyst (fig 1; 76), comprises exposing the catalyst (fig 1; 76) and particulate filter (fig 1; 70) to a first, lower elevated exhaust temperature, in the range 300{C to 450{C, to remove deposits from the catalyst 76 and then exposing the catalyst (fig 1; 76) and particulate filter (fig 1; 70) to a second, higher elevated exhaust temperature, in the range 550{C to 700{C, to heat the particulate filter (fig 1; 70) and decompose particulate matter in the particulate filter (fig 1; 70). The catalyst is an SCR catalyst which utilizes urea as a reductant for NOx removal and the combustion engine is a diesel engine. The deposits on the catalyst include urea and hydrocarbon. In this manner, damage caused to the catalyst (fig 1; 76) due to the decomposition and reaction of the deposits and/or oxidation of stored hydrocarbon during particulate filter regeneration is avoided.

Abstract: A game of the type wherein prizes may be awarded for predetermined winning outcomes is preferably implemented on a remote platform such as a mobile telephone. The game is started either: by a wager of user points wherein it is operable to award user points if a predetermined winning outcome occurs; or, if a player is able to make a suitable payment, by a wager of monetary value wherein it is operable to award prizes with monetary value if a predetermined winning outcome occurs. When playing for monetary value the game operates in a first mode to a first paytable and, in order to improve player entertainment when playing for points the game operates in a second mode to a second paytable, Preferably, the first paytable is designed to be compliant with relevant gaming legislation in the territory where the mobile telephone is located. The second mode may offer additional or alternative bonus games with higher payback percentages. A further game of the type wherein prizes may be awarded for predetermined winning outcomes on a remote terminal includes a multiple player tournament which ranks players according to the final number of user points that they have accumulated.

Title: Calculating allocation factors for producer wells based on characteristics of injector wells
Inventor: SAADATPOOR EHSAN
IPC: E21B43/16
Filed: 2009-10-13
Abstract: A computer program calculates allocation factors for a particular production well in a pattern of multiple production wells and at least one injector well. An allocation factor is the proportion of the fluid produced at a particular well, relative to the total fluid production of the whole pattern. The calculation is based on at least one variable associated with the injector wells. Injection rates, relative distances and the bore radius of the injector well are examples of such variables. Preferably the calculation may be based on one parameter for each corresponding injector well. The parameter is Q x ln(s/r) : the injection flow rate, multiplied by the natural logarithm of the distance to the injector divided by the radius of the injector. The allocation factors can be used to calculate a voidage replacement ratio (VRR). The VRR may influence how the fluid injection is controlled. The program on a disk and a controller to run the program and then control the injection rate are also claimed.

Title: Radar coordinate registration
Inventor: CANON PAUL STEPHEN
IPC: G01S7/40
Filed: 2008-05-30
Abstract: Integration of ionospheric models in over the horizon radars (OTHR) is achieved with very little or substantially no change to existing coordinate registration systems or software by specifying a virtual transponder at a target location and generating a signal which appears to have emanated from a transponder at that location. A return path to said virtual transponder is ray-traced through the ionospheric model to produce propagation parameters; and an appropriately delayed virtual transponder signal is inserted into the receiver. The result produced at the receiver is used to perform coordinate registration for further received signals.
