  • Publication number: 20070112187
    Abstract: The invention relates to a process of recovering arabinose and optionally other monosaccharides from vegetable fiber rich in heteropolymeric arabinose, such as gum arabic. Said other monosaccharides are typically selected from galactose and rhamnose. The process of the invention comprises controlled hydrolysis of the arabinose-rich vegetable fiber and fractionation of the hydrolysis product to obtain a fraction enriched in arabinose and optionally other product fractions followed by crystallization of arabinose. The invention also relates to a novel method of crystallizing arabinose from biomass-derived material. Furthermore, the invention relates to novel crystalline L-arabinose.

  • Publication number: 20070083790
    Abstract: Image or other data is stored in a memory. A first validation parameter (e.g., a checksum) is determined for the data stored in the memory at a first time, and stored. A second validation parameter is determined for the data stored in the memory at a second time, and also stored. The stored first and second validation parameters are then compared. In this manner, corruption of data in the memory may be determined by the comparison. In the case where the compared first and second validation parameters are not identical (within a threshold in certain embodiments), the data stored in the memory is updated. As applied to graphical image data, this is seen as advantageous over the prior art approach of periodically updating a frame memory even when no new image data set is present. Apparatus and computer program products are also detailed.

  • Publication number: 20060282711
    Abstract: The invention relates to a recovery of a hardware module of an electronic device from a malfunction state. The hardware module is connected via a signal line to a recovery component of the device, a state of the signal line being controlled by the hardware module. The recovery component monitors a state of the signal line. Whenever the signal line is detected not to assume a predetermined state during a predetermined period of time, the recovery component causes a hardware reset of the hardware module.

  • Patent number: 7037378
    Abstract: The invention relates to the recovery of deoxy sugars, such as fucose from biomass-derived solutions, such as spent liquors obtained from pulping processes. The invention is based on the use of chromatographic fractionation with specific column packing materials and combinations thereof. The deoxy sugar product obtained from the chromatographic fractionation may be further purified by crystallization. The invention also provides a novel crystalline fucose product and a novel process for the crystallization of fucose.

  • Publication number: 20050220232
    Abstract: A mobile station (10) includes a plurality of sub-assemblies coupled together by a plurality of data communication buses (22) connected to ports (20). At least one port includes a Multi-level Analog Signaling (MAS) circuit arrangement that includes a transmitter to encode data bits represented by multi-level analog signals. A data communications bus that couples the transmitter to a receiver in another port includes at least two multi-level, possibly differential signal buses for conveying the encoded data bits such that, on each multi-level signal bus, during each data bit period the signal level is required to change from a first signal level to a second, different signal level. The transmitter indicates a data boundary, such as the beginning or the end of multi-bit frame, to the receiver by holding one of the multi-level signal buses of the at least two signal buses at the same level for at least two consecutive bit periods.

  • Patent number: 6872414
    Abstract: The invention relates to novel anhydrous (?) lactitol crystals, belonging to the orthorhombic P212121 cystal system and having unit cell constants a=9.6 ?, b=11.1 ?, c=14.0 ?. The invention also relates to crystalline lactitol products containing the novel anhydrous ? lactitol and to a process for the preparation thereof by crystallizing from an aqueous solution of lactitol. The novel anhydrous ? lactitol is stable and nonhygroskopic and it may be used as a substitute for sugar in foodstuffs and sweets, in as well as in pharmaceutical and hygienic products.

  • Patent number: 6821339
    Abstract: The invention relates to a process for the crystallization of substances having a narrow metastable supersaturation zone. In the process the saturation of a solution is gradually increased and the solution is seeded for the crystallization. The seeding is performed at a seeding point which is selected in response to a signal received from said process indicating imminent or initial spontaneous nucleation. The process provides a good crystal yield and a crystalline product having a uniform crystal structure and a narrow crystal size distribution.

  • Patent number: 6821535
    Abstract: The invention relates to a process for the hard panning of chewable cores in a pan or drum wherein a syrup of a crystallizable sugar or polyol is intermittently sprayed over a bed of the cores and the cores are dried between sprayings with a flow of air. The speed and efficiency of the panning process is increased by controlling the drying of the cores between sprayings by controlling parameters of the drying air in such a way as to intentionally leave a substantial residual moisture in the drying coating layer at the start of a subsequent spraying phase. The chewable products are preferably xylitol coated chewing gums.

  • Patent number: 6816974
    Abstract: Use of an especially small-sized and valuable display device (b 31) is limited to persons knowing a password, not by any requirement that a password (33) always be entered when the display device (31) is switched on, but rather detecting, the detachment of the display device (31) from the equipment (35-39) controlling it and measuring its time of being detached, for limiting the use of the display device (31) on the basis of a certain predetermined and adjustable time limit which, when exceeded, requires the password be entered.

  • Patent number: 6756490
    Abstract: The invention relates to a method of crystallizing maltitol from a maltitol solution by supersaturating the solution in repsect of maltitol and crystallizing the maltitol from the solution. In the process of the invention, the maltitol-containing solution is brought to a supersaturated state, and the solution is subjected to evaporation, until a crystallization mass is obtained which has a crystal yield of 1 to 80% on maltitol, and a dry solids content of over 50%. After bringing the solution to a supersaturated state, the solution is preferably seeded by adding maltitol seed crystals. In one embodiment of the invention, additional feed liquid is added during the crystallization by evaporation.
