Inventor: PERSSON TORSTEN
IPC: B03C/
Filed: 1998-12-16
Abstract: A time interval is defined for each of the above combinations and a function of voltage is defined, calculated and integrated under this interval, then a number is obtained by dividing the integral by the pulse length or a pulse factor-dependent scale factor, and then this number is used to chose the desired combination.  A method for regulating the supply of pulsed dc current to high voltage electrodes in an electrostatic separator comprises varying the current frequency, pulse height and/or pulse length in order to obtain a number of frequency-height-length combinations, and measuring the voltage between the emission and precipitation electrodes. A time interval (~t) with a length not exceeding the pulse period time (T = 1/f) is defined for each of the above combinations, where f is the frequency and is not less than the pulse length (t). A function of voltage f(U) is defined, calculated and integrated under (~t), a number is obtained by dividing the integral by (t) or a pulse factor-dependent scale factor, and this number is used to choose the desired combination.

Abstract: A system and method for feeding comminuted cellulosic fibrous material such as wood chips to the top of a treatment vessel such as a continuous digester provide enhanced simplicity, operability, and maintainability by eliminating the high pressure transfer device conventionally used in the prior art. Instead of a high pressure transfer device the steamed and slurried chips are pressurized using one or more slurry pumps located at least thirty feet below the top of the treatment vessel and for pressurizing the slurry to a pressure of at least about 10 bar gauge. A return line from the top of the digester may, but need not necessarily, be operatively connected to the one or more pumps and if connected to the pumps the pressure in the return line may be reduced utilizing a pressure reduction valve and/or a flash tank. During pressurized transferring of the slurry from the pumps to a treatment vessel (which may be as little about 10 feet or as much as about a half a mile away) treatment liquid is provided which contains at least some active pumping chemical including sodium hydroxide, sodium sulfide; polysulfide, anthraquinone or their equivalents or derivatives; surfactants, enzymes, or chelants; or combinations thereof. Pseudo-countercurrent circulation of treatment liquids may be provided between stations.

Abstract: A detailed drawing is used to choose the support points, the coordinates for which are fed into a computer and converted into the centre of a contact sphere. The object (4) being measured is placed in a virtual measurement position and the fixturing arms (1) with the contact spheres are placed close to the actual support point coordinates inside the measurement volume, with the aid of the positions given by the measuring device in the machine. The positions of the contact spheres associated with the arms are measured using the measuring device and any deviation from the chosen position is recorded, then position of the contact sphere is adjusted to the chosen position if necessary, and then the object is introduced with its support points in contact with the arms.  An Independent claim is also included for the fixturing system for carrying out this method.

Abstract: A photosensor system having a photosensor array constituted by two-dimensionally arraying a plurality of photosensors includes a driver circuit for supplying a drive signal to the photosensors, and a controller for controlling reading operation of a subject image and sensitivity setting. Before the start of normal reading operation of a subject image, prereading operation of changing the image reading sensitivity at a plurality of stages for respective rows is executed. A row in an optimal image reading state is easily determined based on the dynamic range distribution of the lightness data of read image data or a dynamic range distribution from which an abnormal value deviating from the main change trend of lightness data is removed, and the linearly differentiated value of the dynamic range. An image reading sensitivity set for this row is set as an optimal sensitivity. This can simplify sensitivity setting processing and shorten the required time.

Filed: 2011-05-05
Abstract: An apparatus for reheating and conditioning an elongate preform for forming a blow moulded container such as a PET bottle comprises a heated receiver 4 with an elongate annular non-cylindrical inner surface 6. The surface 6 defines a cavity and is adapted to engage with, and transfer heat by conduction to, an elongate outer surface of a preform. The surface 6 includes a three-dimensional relief to provide substantially non-uniform contact between the receiver and the elongate preform. The non-uniform contact provides for non uniform heating of the preform. The relief depth may be from 0.01 to 1.5mm and may result in a temperature which is 5 to 15 degrees C higher in areas of the preform in contact with the surface compared with non-contacted areas. The surface may be eliptical and may be used to heat preforms used for forming eliptical bottles. The end of the cavity may be closed by a concave surface 15 into which opens a vacuum duct 30 for applying a negative pressure to hold a preform in the cavity. Alternatively, preforms may swell upon heating in the cavity and consequently may be held in the cavity.

Title: Fast optical wavelength conversion
Filed: 2012-05-14
Abstract: A method and device for converting an input light signal into an output light signal, in an optical component is described. An input light signal, at a first wavelength, and a first light beam which may be at a second wavelength, are received at the component. The input light signal and the first light beam interfere in the component to form an interference pattern, which modifies a reflectivity spectrum of the component to increase the reflectivity of the component in a portion of the reflectivity spectrum. A second light beam, having a second wavelength corresponding with a wavelength within the portion of the reflectivity spectrum, is also received at the component and is then reflected from the component, in dependence upon the portion of the reflectivity spectrum, to generate the output light signal at the second wavelength. This enables conversion of light signals to signals at a different wavelength.

Title: Method and system for cryptographic processing core
Filed: 2011-04-18
Abstract: A combination firmware and hardware cryptographic core architecture is provided for encrypting, decrypting and authenticating data. The core provides flexibility to change and add new cryptographic protocols, while providing increased performance by loading new firmware into a microcontroller that programs behavior of various components in the core. The core combines a microcontroller programmable by firmware, and flexible aligner, insertion and removal controllers programmed by the microcontroller that process, manage and manipulate an incoming data stream as it moves through the core. The firmware may be reprogrammed upon an enhancement or change to a protocol while still realizing performance benefits of the hardware. Reprogramming the microcontroller allows it to change the way the aligner, insertion and removal controllers manipulate the data stream as it enters various components. Such systems provide redesign time savings compared to hardware cryptographic core architectures, and improved speed and throughput compared to software cryptographic core architectures.
