Title: A vehicle status and environment based navigation system
Inventor: DUSTERHOFF KURT
IPC: G01C21/34
Filed: 2006-08-10
Abstract: A navigation system provides guidance with respect to an instruction point along a route at which an action is required. A guidance point 37 is determined dynamically at which the guidance is to be given for the instruction point 38. A distance Z of the guidance point from the instruction point is determined by modifying a base distance Y by factor representative of vehicle and/or environment status. The guidance point 37 is compared to a current vehicle position determined by a vehicle positioning system. The guidance is output via a user interface in response to determining that the current vehicle position has reached the guidance point Z.

Title: Magnetic resonance imaging scanner
Inventor: HILLS BRIAN PHILIP
IPC: A61B5/055
Filed: 2006-11-28
Abstract: A magnetic resonance scanning apparatus has a first magnet having a ring shape occupying an x-y plane and configured to generate, within a sampling volume defined within, and in the plane of, the ring, a Bo magnetic field in the z-direction. Axial inhomogeneity outside the x-y plane is also provided. This is a means of slice selection. The Bo field has linear radial inhomogeneity in the x-y plane, which is a means of selecting a contour slice (a circumferential portion of the sample extending around the z-axis and in the x-y plane of the sampling volume) within the sampling volume via variable frequency rf. A second magnet is configured to generate, within the sampling volume, a gradient field having a field in the z-direction and gradient dBz/du where u is an axis in the x-y plane, such as the x or y axes.

Title: Formation sampling for heavy oil formations
Inventor: GOODWIN ANTHONY H
IPC: E21B43/24
Filed: 2007-09-14
Abstract: A method of retrieving a fluid from a formation 54 adjacent a borehole wall includes estimating at least one of a permeability of the formation, a viscosity of the formation fluid, and a mobility of the formation fluid. A tool is selected based on the estimation, the tool being selected from one of a heating and sampling tool 150, an injection and sampling tool (50, fig 3), and a coring tool (30, fig 2). A formation fluid sample is then retrieved from the formation. A sampling system may comprise an extendable probe 154 and a heat source 172. The heat may be delivered via a hole 168 opened by a drill bit 164. In another aspect, a first retrieval process is initiated; the mobility is measured before changing the first retrieval process. A second retrieval process is then initiated, also increasing the mobility of the formation fluid. The sample is then retrieved.

Title: Communication of new process measurements is carried out only when necessary
Inventor: BLEVINS TERRENCE L
IPC: G05B11/01
Filed: 2008-09-04
Abstract: A method and device for monitoring parameters in a process reduces power consumption and bandwidth requirements in the transmission of the monitored parameter to for example, a monitoring application. In particular, new monitoring parameter values are only transmitted if the difference between a measured or calculated parameter value and the most recently transmitted value exceeds a limit, or if the time since the last communication of the parameter value exceeds a preset refresh period. The determination as to whether to transmit the parameter can be applied to engineering unit values or raw values.

Title: Improvements in and relating to the recovery of sulphur from solutions of ammonium polysulphides
IPC: C01B17/06
Filed: 1927-04-12
Abstract: 269,546. I. G. Farbenindustrie Akt.- Ges. April 16, 1926, [Convention date]. Ammonia, distilling.- Ammonium polysulphide, ohtained for example in extracting sulphur from materials by treatment with ammonium Sulphide solution is treated under pressure with steam so that sulphur which separates out is in a molten condition. Polysulphide solution is forced by a pump P through a heat-exchanger W and discharged into the top of a column K, which may be packed with porcelain balls, Raschig rings, aluminium, &c., or may be formed with perforated or bubbling hood trays. Steam under a pressure of 2-3 atmospheres is admitted to the base by a pipe d. Sulphur separated in liquid form settles to the base of a lower vessel B and is drawn off through an outlet a. Water is discharged through a rising pipe b and the heat-exchanger W. Vapours pass from the top of the column through a pressure-release valve V and are condensed to form a solution of ammonium sulphide. The pressure in the column may be maintained by forcing the condensate upwards through a vertical pipe about 15 metres in height.

Title: Improvements in the teeth of gear wheels
IPC: B23F9/10
Filed: 1922-04-10
Abstract: 200,213. Llewellin, W. M. April 10, 1922. Gear - cutting. - Toothed wheels, the teeth of which are curved across the width of the wheel, are cut from a blank M by a rotary cutter N inclined as shown in Fig. 5, the centre line of the cutting projection P passing through the blank centre. This method produces a wheel in which the dedenda are greatest at the tooth centres, and the blank may be so formed that the addenda are increased at the centre to correspond, as shown in Fig. 6. The cutter is so inclined that the width and depth of the tooth space at any point is proportional to the shortest distance between the teeth summits at that point. The usual feeding-in motion is superposed to produce an involute profile. Bv using a fly-cutter, the blank may be indexed without withdrawing the cutter. The convex and concave faces of the teeth may be separatety cut by cutters with inner and outer cutting edges of the same radius. For finishing, an abrading wheel replaces the cutter. Two or more series of teeth side by side may be cut across the width of the blank, and the convex faces of adjacent series may face in opposite directions.
