The method is for controlling a sodium and sulphur balance of a pulp mill while separating lignin from black liquor. Lignin is precipitated by using an acid followed by filtration. The lignin filter cake thus obtained is re-suspended in acidic liquid and dewatered to form a second cake. The filtrate obtained after dewatering of the second cake is returned for washing and suspension of the first cake. Sodium sulphate-rich ESP (electrostatic precipitator) dust produced in the recovery boiler is used in the washing of the precipitated lignin cake.

EL display elements are configured by sequentially laminating an anode, an emissive layer and a cathode, and emit light of R, G, and B. Each EL display element is supplied with a drive current from an EL element driving TFT. The transistor sizes of the EL element driving TFTs connected to the display pixels for respective colors are designated such that the size of the TFT for a green display pixel including an EL element having the highest emissive efficiency is the smallest, and the sizes of the TFTs for red and blue display pixels having sequentially decreasing emissive efficiency are made sequentially larger.

A display device and a driving method thereof in which if an input 2D/3D video signal is a 2D video signal, an image data signal is generated by applying a first gamma correction curved line. If the input 2D/3D video signal is a 3D video signal, an image data signal is generated by applying the second gamma correction curved line. Luminance of a maximum grayscale of the first gamma correction curved line is set to be lower than luminance of a maximum grayscale of the second gamma correction curved line. Therefore, it is possible to prevent luminance of the display device from deteriorating by a barrier in a 3D driving mode.

A self-sufficient material property profile regulation method and system, for adjusting fluid property profiles such as in an ocean of multiple property layers, is described. Using this Fluid Property Regulator, the property profiles of a non-enclosed material, including property profiles related to material density, chemical characteristics and space-time position, are affected due to motion of the material relative to a body in the flow stream. The state of other matter with which the initial material then makes direct or indirect contact is also affected. For example, in the case of a liquid such as an ocean current, the temperature, salinity, nutrient content and other properties may be destratified (i.e. layers being combined) as the system lifts large quantities of deep water and combines this material with surface water in the downstream far-field region of the system. The resulting regulation of such ocean water property profiles may then also indirectly affect the properties of the atmosphere above the ocean so that the system can be said to affect planetary properties both oceanic and atmospheric. Rather than merely discharging a pumped material, such as cold water that might quickly re-submerge, the system regulates lasting property profiles. The new Fluid Property Regulator system described in this invention regulates material properties to produce desired outcomes such as increased food and energy production as well as to prevent undesirable outcomes such as hurricanes, elevated planetary temperatures, decreased planetary ice sheet size, raised sea level and glacial freshwater incursions that can halt important major currents.

Mechanically harvested chili-pepper plants are sized into chunks and introduced into a water flotation system. Water is added at the top of a flotation vat and, for the most part, is withdrawn at the bottom using a venturi unit. The balance of the water is recovered as spillover from the top of the vat carrying the floating material. If the rate of water withdrawal at the bottom of the vessel is controlled such that it is as high as possible but less than what produces turbulence in the vat, the pulp material will drop with heavy seeds to the bottom with the extracted water while all other materials are skimmed away at the top. The very small differential in density between the pepper pulp and the rest of the plant and debris is sufficient to separate them under these specific conditions.

The present invention provides novel techniques for controlling the balance between energy usage and biofuels dehydration between a distillation process unit and molecular sieves with model predictive control technology. In particular, the present techniques are presented in the context of biofuel production, wherein control of the balance between energy usage and water removal in biofuel production may be optimized. However, the present techniques may also be applied to any other suitable applications, such as liquor processing, where energy may be used to remove water from the liquor.

The invention is a self-cross-linked polyvinyl butyral (PVB) binder for organic photoconductors (OPC's) used in electrophotography. The no cross-linked form of the binder is available from Monsanto Co. in the U.S.A. a Butvar TM , and from Sekisui Chemical Co. in Japan as Slek TM . I discovered that the PVB may be self-cross-linked by subjecting it to a thermal cure at between about 150 DEG -300 DEG C. for about 2 hours. I think other ways of cross-linking, for example, e-beam, UV or X-ray radiation, will achieve results similar to those I obtained with heat. No cross-linker, nor cross-linkable copolymer nor catalyst is required to accomplish the cross-linking. After self-cross-linking, the PV has good mechanical durability and good anti-solvent characteristics. In addition, he self-cross-linked PVB's glass transition temperature (Tg) increases from about 65 DEG C. to about 170 DEG C. Also, when conventional photoconductor pigments are dispersed in the self-cross-linked PVB, they are well dispersed, and the resulting OPC's have good charge acceptance, low dark decay, and, in general, good photodischarge characteristics. Also, OPC's with the self-cross-linked PVB exhibited improved adhesion, so multi-layered OPC's made according to this invention will hav improved inter-layer bonding and longer economic lives.

The invention relates to a three-level ANPC convertor neutral-point voltage balance control method. The method comprises the following steps of (1) acting on a three-level ANPC convertor through an SVPWM (space vector pulse width modulation) pulse sequence; (2) detecting the voltage of the direct current side capacitor of the convertor in real time to obtain a neutral-point voltage, and comparing the neutral-point voltage with a reference neutral-point voltage to determine whether the direct current side capacitor requires charging or discharging; (3) in real time detecting the positive and negative direction of the three-phase load current of the convertor; (4) integrating detecting values of the steps (2) and (3), within every switching period, dynamically adjust the duty ratio of the zero state of the switch sequence of a three-phase bridge arm until neutral-point voltage balance, and repeating the step to maintain fluctuation of the neutral-point voltage within a relatively small range.
