Title: Cleaning contaminated materials
Inventor: CROWTHER NICHOLAS JOHN
IPC: C08F26/06
Filed: 2004-09-28
Abstract: Oil contaminated drill cuttings are contacted with an oil soluble surfactant with agitation which causes the hydrophobic moiety of the surfactant to interact with the oil. Next, an aqueous polymer formulation comprising a polymer having polar and/or ionic functionality is added and mixed. Then, an excess volume of water is added with gentle agitation and the mixture is allowed to settle, whereupon the cuttings sediment to the bottom of the receptacle in which the process is undertaken and the supernatant contains a colloidal suspension of particles which comprise oil, surfactant and polymer. The drill cuttings may then be separated from the supernatant by filtration. The supernatant may be treated with a flocculating agent to cause the colloidal particles to sediment. They too may then be separated.

Title: Stepwise Increasing Pass Transistor Gate Voltage During a Programming Period
Inventor: LEE JIN-YUB
IPC: G11C16/12
Filed: 2006-11-17
Abstract: Programming cells in a NAND type flash memory device includes driving signal lines (S0 to Sn-1) corresponding to word line (WL0 to WLn-1) with word line voltages comprising either a pass (unselected) voltage or a program (selected) voltage. A block of word line are then enabled during a program execute period by supplying a block word line voltage VBLKWL to pass gate circuit 1700. The block word line voltage is increased stepwise and supplied as the gate voltage of block select transistors (WT0 to WTn-1; figure 2) connected between the selected word line and the signal line during the program execute period. Incrementing the gate voltage in the pass gate circuit in this way reduces the occurrence of soft programming of adjacent cells with a gradual transition to word line voltage unlike the sharp transitions seen with incremental step pulse programming (ISPP).

Stopper 37 may be adjustable to alter the centrifugal force required to overcome the grip of the stopper. A flexible buffer (72, fig.3C, 3D) may be provided which automatically urges the door arresting projection 25 back to its initial retracted starting position. A second door arrestor may be provided retained in initial retracted position by engagement with the first door arrestor and urged into an extended position by a spring (figure 4A, 4B). The anti-slamming device may be mounted on the surface of a door or within the door, particularly within a vehicle door.

IPC: F03D7/06
Filed: 2008-03-20
Abstract: In a wind turbine system 10, a turbine 26 is arranged to be driven by the wind for rotation about a vertical axis. A continuously variable gearbox 34 has an input 14 arranged to be driven by the turbine 26 about the vertical axis. An electrical generator 46 and a flywheel 56 are arranged to be driven by an output 18 of the gearbox.

Title: Frequency tuning of disc resonator gyroscopes via resonator mass perturbations based on an identified model
Inventor: SCHWARTZ DAVID
IPC: G01C19/5684
Filed: 2009-06-10
Abstract: The invention relates to tuning of disc resonator gyroscopes (DRGs) in order to reduce the frequency split between the Coriolis coupled modes by perturbing the mass distribution of the disc resonator based on an identified model. A method of tuning the resonator comprises measuring a frequency response matrix of the resonator 1702, the frequency response matrix having a plurality of inputs and a plurality of outputs, and the resonator having a plurality of coupled resonance modes. A structural mechanics model of the resonator is fitted to the frequency response matrix 1704 to identify parameters of the structural mechanics model including mass, damping and stiffness matrices, and their sensitivity to mass perturbation. The amount of mass perturbation to the resonator is then estimated to improve the degeneracy of the plurality of coupled resonance modes based on the identified parameters of the structural mechanics model. The mass perturbation may comprise removing mass by a laser ablation process, or may comprise adding mass by a mass deposition process. The DRG may comprise a microelectromechanical system (MEMS) disc resonator gyroscope.
