Title: Microwave type concentration measuring apparatus
Inventor: SUZUKI ETSUMI
IPC: G01N22/04
Filed: 1998-09-10
Abstract: The present invention finds the overall concentration of a mixture in the following way.  It measures the measurement sensitivity of substance C, of which the constituent composition varies, out of multiple substances A, B and C using sensitivity measuring microwave type concentration meter 17.  It then inputs this measurement result to calibration curve gradient setter 20.  It then finds the calibration curve gradient using a computing device which possesses the relationship of the measurement sensitivity of the single substance of which the constituent composition varies to the calibration curve gradient that finds the overall concentration of substances A, B and C.  It then sets this calibration curve gradient in mixture concentration measuring microwave type concentration meter 18.  Then, based on the setting of this gradient, it finds phase difference .DELTA..theta. = (.theta.2 - .theta.1) from phase lag .theta.1 of microwaves which are diffused by a reference liquid and phase lag .theta.2 of microwaves dispersed by the mixture.  At the same time, it finds the overall concentration of the mixture using the calibration curve (= a.DELTA..theta. + b) corresponding to the mixture.

IPC: C12Q1/68
Filed: 1997-05-13
Abstract: On procède sur des échantillons à des tests de détection de mutations sur des gènes BRCA1 par une approche hiérarchique. Tout d'abord chaque échantillon est amplifié au cours d'une ou de plusieurs réactions d'amplification PCR multiplexée. Chacune des réactions d'amplification PCR multiplexée produit un mélange de fragments amplifiés. La taille et la quantité de ces fragments est évaluée et comparées à des valeurs de référence reflétant la taille et la quantité des fragments obtenus lorsque la même amplification multiplexée est effectuée sur un gène BRCA1 de type sauvage. Les différences entre la taille et/ou la quantité des fragments observés et celles des gènes de type sauvage indique une mutation du gène BRCA1 de l'échantillon. On procède ensuite à un séquençage d'un ou plusieurs des exons du gène BRCA1 ne portant de préférence que sur ceux des échantillons où aucune mutation n'a été décelée par analyse des fragments produits par PCR multiplex. Le processus de séquençage peut s'effectuer par amplification et séquençage du mélange obtenu par amplification multiplex.

Title: Method and apparatus for stopping a welding process
Inventor: MEHN PETER
IPC: B23K9/095
Filed: 1999-01-19
Abstract: A method and apparatus for stopping a welding process includes monitoring the status of the arc. The output current is commanded to a level sufficient to clear a short if a short circuit forms when the process is stopping.    A low current level is commanded after the short has cleared. The low current level is sufficiently low to prevent the forming of a large ball. This is repeated until a short does not form. The wire feed speed is monitored, and the stopping process begins when the wire feed speed drops below a threshold. The stopping process is performed with, a MIG process, a pulsed spray process, and a short circuit transfer welding process. The arc voltage is monitored to determine the status of the arc. The motor is commanded to stop in response to receiving a user provided stop command, and the braking of the motor is controlled.      At least one output parameter may be reduced before the threshold is reached, but after receiving the stop signal in another alternative embodiment.

Title: Easy-to-adjust grader
Inventor: LEDET BRENT A
IPC: B07B1/46
Filed: 1999-03-03
Abstract: An easily adjustable grader for sizing and sorting food products, especially shellfish such as shrimp. The grader includes a series of parallel rotating rollers attached at either end to drive chains. The drive chains include adjustment levers attached rotatably at each roller position. The levers have a first arm terminating in a rolling wheel and a second arm whose end conforms to the chain. An adjustment rail is positioned above each chain along the length of the grader. The wheels of the levers ride along cam surface on the underside of the rail. Rail adjusters at each end of the rail raise and lower each end of the rail to change the spacing between the cam surface and the chain along the length of the grader.  The pressure exerted by the cam surface on the lever causes the chain to kink in proportion to the distance between the cam surface and the chain, which adjusts the gap between consecutive rollers.      The widths of the gaps determine the size gradations of the grader.

Title: Method of compensating the dispersion of fluoride-based fibre lasers in the second optical window
Inventor: PEUPELMANN JENS
IPC: H01S3/098
Filed: 1997-09-13
Abstract: The invention concerns a method of manipulating a compensation fibre such that it can compensate the high negative dispersion of a fibre laser in the second optical window. According to the invention, the active fibre of the fibre laser is linked to a compensation fibre which consists of a step-index quartz glass core with a sheathing. By doping the compensation fibre sheathing with fluorine in a targeted manner, a positive value is set for the dispersion of the compensation fibre. Subsequent dimensioning of the length of the compensation fibre increases the set dispersion value to the positive dispersion value necessary for complete compensation of the dispersion of the fibre laser.

Title: Processing of state histories in viterbi decoding
Inventor: HUNT ANDREW
IPC: H03M13/45
Filed: 1999-06-01
Abstract: A simplified method of history handling for the Viterbi decoding of convolutional codes is described herein. The state number, or one or more of the most-significant bits of the state number, is loaded into the corresponding state history. Each state number represents the sequence of data bits that, in convolutional encoding, would give rise to the corresponding state. The most recent data bit provides the least significant bit of the state number. This invention reduces the processing requirements associated with the handling of the history, and is especially useful for decoder implementations using general-purpose processors.
