Title: A pulse magnetron
Inventor: OBATA HIDEYUKI
IPC: H01J25/587
Filed: 2003-10-28
Abstract: A pulse magnetron includes an anode 1 with a plurality of anode vanes 12, a cathode 2 provided at the centre of the anode 1, and a pair of pole pieces 3 provided for applying a magnetic field to an interaction space 4. The cathode 1 and/or the inner ends of the anode vanes 12 (see figure 6) may be shaped such that they have a generally concave profile in an axial direction. In other words, the radial distance between the cathode 2 and anode vanes 12, is greater at the centre of the interaction space in a longitudinal direction, than at either end. In this manner the magnetron may inhibit unwanted oscillation during the rise or decay of a pulse, attenuate spurious radiation at frequencies lower than the fundamental oscillation frequency, and produce a an output spectrum with a more symmetrical profile.

Title: An electrostatic discharge device with movable shield
Inventor: YU YAT SHUN
IPC: H01R13/631
Filed: 2003-12-22
Abstract: An electrostatic discharge protection shield device, which may be used in bases or cradles for mobile electronic apparatus among other uses, comprises a non-electrically conductive base for supporting an electrical connector, an electrically conductive shield member movably mounted on the base, and a biasing mechanism. The electrically conductive shield member is movable between a first position in which it protects the electrical connector from undesired contact, and a second position in which the electrically conductive shield member exposes the electrical connector for normal operation in contact with a corresponding electronic apparatus. The biasing mechanism prompts the shield member into its first position. Preferably the biasing member is a helical spring mounted around a guide member to produce a sliding action parallel to an engagement axis of the electrical connector. Furthermore, the helical spring is preferably conductive such that it forms an electrical ground configured to remain in electrical contact with the electrically conductive shield member throughout the movement of the shield member, for permitting conduction of electrostatic discharges away from the electrical connector.

Title: Vehicle differential control
Inventor: PRINS JAN PIETER
IPC: B60W10/12
Filed: 2004-01-24
Abstract: A vehicle comprises a differential controller 28 arranged to control the degree of locking of its centre 22, front 24 and rear 26 differentials. The differential controller is arranged, on failure of various components or systems on the vehicle to enter a failure mode in which its operation is modified so that the differentials 22, 24, 26 are locked when the vehicle speed is low and unlocked when it is high. This maximises traction at low speeds to aid vehicle recovery, and reduces the interference from the differentials with operation of systems such as the stability control system at higher speeds.

Title: Plastically deforming and radially expanding an expandable tubular member
Inventor: RING LEV
IPC: E21B23/00
Filed: 2002-08-13
Abstract: Apparatus 300 is inserted into a tubular member 120 which causes an upper end 120b of the tubular member to impact collets and compress springs so as to apply axial biasing forces to a split ring collar 330 and expansion cone segments 325. The segments 325 are thus maintained in a position that is less than the inside diameter of the tubular member 120. Also an axial biasing force is applied to a tubular sleeve to prevent it from covering a radial passage 315d in a tubular support member 315. Thus, fluids within the interior 315a of the tubular support member 315 may pass through the radial passage 315d into the annulus between the apparatus 300 and the tubular member 120 thereby preventing over pressurization of the annulus. After positioning the apparatus 300 beyond lower end 120c of the tubular member 120, the apparatus is then repositioned partially back within the tubular member 120. During the re-insertion, the lower end 120c of the tubular member impacts the collets and compresses the springs to seal off the radial passage 315d and drive the expansion cone segments 325 up expansion cone support body 315i. An upward axial force is then applied to the tubular support member 315 to radially expand and plastically deform the tubular member 120.

Patent GB-2415154-A (GB)
Title: A separate size flotation device
Inventor: BOURKE PETER GERARD
IPC: B03D1/14
Filed: 2004-03-16
Abstract: The invention provides of flotation device including a series of flotation tanks (1) for processing a slurry incorporating valuable minerals for extraction. At least one of the tanks includes a side outlet (15) adapted for the withdrawal of targeted relatively fine coarse particles from the slurry. The tanks also include a bottom outlet (14) for the withdrawal of relatively dense or coarse components of the slurry. The incorporation of bottom and side outlets allows the slurry to be separated into two parallel streams, one configured for optimal recovery of the relatively coarse or dense slurry components and the other for optimal recovery of the relatively fine slurry components. In this way, outflow slurry from downstream tanks in the coarse particle stream has a higher proportion of coarser particles than was present in the inflow slurry from the upstream tanks. Consequently, when a flotation reagent is added to the slurry in the downstream tanks, there is a greater probability of coating some of the larger particles. Therefore, the probability of floating these larger particles increases in the downstream tanks. This in turn increases the overall efficiency of the flotation process.
