Title: Dual control line system for operating a sub-surface safety valve
Inventor: SMITH RODDY R
IPC: E21B34/10
Filed: 2008-06-04
Abstract: A control system for a surface controlled sub-surface safety valve 10 has first and second control lines in communication with a control port 12. A one-way connecting valve 58 is connected between the control lines. The connecting valve allows control fluid to communicate from the first control line 52A to the safety valve but prevents fluid communication from the second control line 52B to the first control line. The control lines preferably have respective sumps 54 and filters 56. In a second aspect, the valve is opened by communicating pressure to the control port via the first control line and exhausting pressure from the control port via the second control line. Preferably, the second control line can be use to open the safety valve in the event of a failure with the first control line, thereby providing redundant control. The dual control lines can also be cycled to flush debris from the system. A control line sump is also provided.

Title: Setting the clock frequency of a processor based on the amount of work the processor has to do in a time segment
Inventor: AZUMA HIROYUKI
IPC: G06F1/08
Filed: 2009-06-17
Abstract: A computer system has a main processor and a sub processor. The main processor determines what tasks are to be executed by the sub-processor in the next time period. It then determines the clock frequency at which the sub-processor must run in order to ensure that the task will be completed during the time segment. Just before the start of the time segment, the main processor sets the clock frequency of the sub-processor to the determined value. The time segment may be a frame period followed by a clock switching period. The system may use a list of tasks with the number of clock cycles required for each task to calculate the required frequency. The main processor may load the task to be executed into memory shared with the sub-processor.

Title: Handling integer and floating point registers during a context switch
Inventor: CRASKE SIMON JOHN
IPC: G06F9/46
Filed: 2009-06-19
Abstract: Data processing circuitry operable to execute integer data processing operations and floating point data processing operations comprises a set of integer registers and a set of floating point registers. During a context switch in response to an interrupt request, the circuitry performs one of an integer state preservation function in which at least a subset of only the integer registers are copied to a stack memory, and a floating point state preservation function in which at least a subset of both the integer registers and the floating point registers are copied to the stack memory. The appropriate preservation function is selected by the processing circuitry in dependence on state information which indicates whether or not the current data processing context uses a floating point register. In this way, it is possible to reduce the memory size requirement through reduced stack sizes, and to reduce the number of memory accesses required compared with the basic solution of always preserving floating point registers. As a result, power usage and interrupt latency can be reduced.

Title: An improved method of soil nitrogen estimation
Inventor: GRUNDY ALLISON
IPC: G01N33/24
Filed: 2009-06-22
Abstract: A method of determining the quantity of nitrogen fertilizer required to bring the level of plant usable nitrogen in the soil comprising (i) taking a plurality of samples of soil to a depth of 30cm in the area ; mixing the samples together; (ii) analysing a portion of the mixed sample to determine the amount of soil mineralisable nitrogen (SMN); (iii) analysing a portion of the mixed sample to determine the potentially mineralisable nitrogen (PMN); (iv) from a first database using a conversion factor to the PMN to yield an additionally available nitrogen; (v) from a second database obtaining values for nitrogen uptaken from a comparable crop; (vi) obtaining a nitrogen percentage of fertiliser to be added to the soil; and (vii) calculating the amount of nitrogen needed. The method uses databases containing data on, for example, uptake of nitrogen for a crop, utilisation factors of available on nitrogen in a soil, rainfall values etc. In order to perform an accurate calculation a factor is devised which, when applied to the measure potentially mineralisable nitrogen (PMN) value enables a good estimate of the quantity of nitrogen accessible by a plant from this source. Correction factors can be introduced into the method where it is known that organic fertilizer such as manure has been applied to the soil within the previous 24 months.

Title: Phosphine-borane compounds
Inventor: MAYAMA DAISUKE
IPC: C07F9/54
Filed: 2009-12-11
Abstract: A phosphine-borane compound is represented by formula (P-1) (wherein R1 and R2 are independently H or substituted or unsubstituted hydrocarbyl; R3 is an asymmetric hydrocarbon group or an asymmetric substituted hydrocarbon group). The synthesis of (P-1) may be achieved by subjecting a hydrogen phosphine borane (P-2) to a coupling reaction with an optically active isocyanate (3). Since (P-1) may comprise diastereomers (as R1 and R2 may induce asymmetry in the phosphorus atom), optical resolution is possible (e.g. via crystallization). Decomposition of optically pure (P-1) may give optically pure (P-2). (P-1) maybe tert-butyl (methyl) [N-((S)-1-phenylethyl)carbamoyl]phosphine-borane, adamantyl(methyl) [N-((S)-1-phenylethyl)carbamoyl]phosphine-borane or 2,5-dimethyl-1-[N-((S)-1-(1-napthyl) ethyl) carbamoyl]phosphorane-borane. Optically pure (P-2) may be useful to prepare (S, S)-2,3-bis(tent-butylmethylphosphino)quinoxaline (QuinoxP (RTM)) or (R,R)-1, 2-bis(tertbutylmethylphosphino)ethane diborane (BisP* diborane).
