Abstract: The invention concerns a method for purifying aluminium by segregation to form a solid mass or bloom with high purity (namely higher than 3N5, i.e. containing more than 99.95 % aluminium), from an impure aluminium mass called mother liquor, and comprising the formation of crystals by partial crystallisation, periodically compacting the bloom and a substantially continuous refusion of the bloom by heating during growth, periodically measuring the height H of the bloom during growth and adjusting the heating power on the basis of the measured height H, so as to obtain a progression speed of the height which is preferably determined and decreasing in time. The invention also concerns a device for purifying aluminium, capable of forming a solid mass (or bloom) with high purity by segregation, comprising a refractory crucible, a furnace provided with means heating the crucible, means for remelting said bloom at least partially during growth, and at least compacting means. The invention is characterised in that it comprises means for measuring the height H during growth and means for controlling the heating power of said heating means on the basis of the measured height H, so as to obtain a height progression speed which is preferably determined and decreasing in time.

Title: Structure for fuel cell active electrode layer with solid polymer electrolyte
Inventor: BRONOEL GUY
IPC: H01M8/10
Filed: 2000-01-07
Abstract: The invention concerns a fuel cell electrode with solid polymer electrolyte comprising in its active layer at least two distinct domains: one is in particular the site of electronic transfer electrochemical reactions, the other serves only for ionic conduction. Said novel electrode structure for fuel cell with solid electrolyte polymer is designed the current density levels at the electrodes by increasing the thickness of the efficient part of their active layer. To achieve this, the ionic conduction in the active layer thickness is reinforced by adding, in specific content, impregnated fibres of the ionic conductor. Moreover, conditions are produced such that the surfaces comprising the platinum sites are coated with a film, uniform if possible, whereof the thickness should not exceed a predetermined value. Finally, it is optionally advantageous to place in the active layer micro-tubes which will promote the transfer of gas phases.

Title: Node unit and state notice information acquiring method
Inventor: MATSUNO KAZUYOSHI
IPC: H04J3/14
Filed: 2002-03-22
Abstract: If the number of frame synchronization protecting stages for the transmission signal is m (m is a natural number) and the number of protecting stages for the state notice information is n (n is a natural number), when the expression n ~ m < n × 2 holds, the contents shown in the state notice information corresponding to a k-th stage (where k is a natural number fulfilling the expressing m < k ~ n × 2) frame using time X as a reference are regarded as valid among the contents shown in the state notice information protected over n stages using time X as a reference. Here, time X is the time when Out of Frame occurred. As a result of protecting m stages using time X as a reference, when Out of Frame of the transmission signal has been sensed, the contents shown in the state notice information corresponding to at least the (n + 1)th stage frame and later using time X as a reference are regarded as invalid among the contents shown in the state notice information protected over n stages using time X as a reference.

Title: Pre-dyeing treatment process and dyeing process for fiber products containing highly crosslinked polyacrylic fibers, pretreated fiber product, and fiber product
Inventor: SAKAMOTO TAKAMASA
IPC: D06P3/82
Filed: 2001-09-14
Abstract: In fiber products (e.g. yarns, woven fabrics, knit fabrics) comprising highly crosslinked polyacrylic fibers (made of acrylic fibers by partially hydrolyzing a nitrile group to generate an amido group and a carboxylic acid group), fibers blended with the highly crosslinked polyacrylic fibers can be dyed in an even hue. A pre-dyeing treatment process for such fiber products (e.g. yarns, woven fabrics, knit fab-rics) comprising highly crosslinked polyacrylic fibers comprises a pretreatment step of immersing the fiber product into an acidic solution and treating it at a high temperature and an elevated pressure. A dyeing process comprises the steps of conducting this pre-dyeing treatment process, and thereafter conventionally dyeing fibers which are blended with the highly crosslinked polyacrylic fibers. A pretreated fiber product and a fiber product are obtained by the pre-dyeing treatment process and the dyeing process mentioned above.
Patent CA-2397510-A1 (CA)
Title: Tongs monitor with learning mode
Inventor: NEWMAN FREDERIC M
IPC: G01L5/24
Filed: 2002-08-12
Abstract: A tongs monitor for monitoring the tightening of tubing, casings, and sucker rods of a well is selectively operable in a learning mode and a monitoring mode. A target tightness value is determined during the learning mode. Subsequent tightness values are then compared to the target value. For example, a first connection is tightened in a conventional manner, while its tightness is monitored during the learning mode. If the tightening process went well, then an operator pushes a button that tells the monitor to remember how tight the first connection was tightened. The tightness value of that first joint then becomes the target tightness value for any subsequent joints. As additional joints are tightened, their tightness are monitored and compared to the first one to ensure that all the joints are as good as the first one within an allowable tolerance.

Title: Electrical detector for adaptive control of chromatic dispersion in optical systems
Inventor: HENNING CHRISTOPHER
IPC: H04B10/2525
Filed: 2001-02-16
Abstract: An optical device for detecting chromatic dispersion is described. The optical device includes a receiver, which converts an optical signal into an electrical signal having a plurality of frequency components. A bandpass section separates the plurality of frequency components and a gain section amplifies each of the plurality of frequency components of the electrical signal. Each of the spectral components has a corresponding voltage level and each voltage level may be compared to known voltage levels of a signal having little or no chromatic dispersion. From this comparison, the amount of chromatic dispersion may be determined. The optical device may be used as an element of a chromatic dispersion compensation device, or as a stand-alone device for measuring the amount of chromatic dispersion in an optical signal.  A method of compensating for chromatic dispersion in real-time based on the optical device and dispersion compensator is also described.
