Title: Flexible method for monitoring fuel cell voltage
Inventor: RIPLEY EUGENE V
IPC: H01M8/04
Filed: 2000-05-17
Abstract: A method for equalizing the measured voltage of each cluster in a fuel cell stack wherein at least one of the clusters has a different number of cells than the identical number of cells in the remaining clusters by creating a pseudo voltage for the different cell numbered cluster. The average cell voltage of the all of the cells in the fuel cell stack is calculated and multiplied by a constant equal to the difference in the number of cells in the identical cell clusters and the number of cells in the different numbered cell cluster. The resultant product is added to the actual voltage measured across the different numbered cell cluster to create a pseudo voltage which is equivalent in cell number to the number of cells in the other identical numbered cell clusters.

Title: Therapie anticancereuse par differenciation a base de cea/nca
Inventor: ORDONEZ-GARCIA COSME
IPC: C07K14/705
Filed: 1999-02-11
Abstract: La présente invention porte sur une nouvelle thérapie anticancéreuse basée sur l'interférence avec la fonction ou sur la rétro-régulation de CEA/NCA en surproduction qui joue un rôle instrumental dans l'action tumorigène et l'évolution maligne par son activité bloquant la différenciation. Plus précisément, l'invention porte sur trois sous-domaines de séquences courtes d'acides aminés du domaine N de CEA et NCA qui, appliqués sous forme de peptides, mimétiques peptidiques ou anticorps monoclonaux anti-sous-domaines sur des tumeurs malignes surproductrices de CEA/NCA, les induisent à se différencier, ce qui inhibent leur capacité à se développer et à accroître l'efficacité d'autres modes de traitement. L'invention porte également sur quatre autres moyens de libérer le bloc de différentiation imposé par CEA/NCA. On peut s'attendre à ce que l'état de différenciation amélioré des cancers induits par ces nouveaux modes de traitement à base de CEA/NCA augmentent virtuellement l'efficacité de tout autre mode de traitement en renforçant l'effet du témoin, plusieurs cellules cancéreuses différenciées normalisant le comportement des cellules cancéreuses adjacentes moins différenciées.

Abstract: A golf club alignment device to be secured to an outer surface of a golf club shaft. The device comprises a band of material having first and second markings positioned at first and second ends of a central portion, the markings being of contrasting visual appearance relative to the central portion of the band, with the markings preferably being light in colour and the central portion of the band preferably being dark in colour. The contrasting visual appearance of the markings and the central portion create visual transition points between the markings and the central portion of the band. The transition points between the markings and the central portion of the band are spaced apart by a distance such that, when the band is applied to the cylindrical surface of the golf club shaft with the center point of the central portion coincident with the rearmost point of the shaft, the transition points are located at 180 degrees to one another and at 90 degrees to the rearmost point on the shaft. When the device is installed on the golf club shaft, the central portion of the band extends about the rear face of the shaft, while the contrasting markings wrap around the front face of the shaft. The golfer aligns the club by sighting down along the front face of the shaft and rotating the club until both of the outer markings are visible while no part of the central portion is visible to ensure that the striking face of the golf club is properly aligned relative to the intended path of ball travel. The alignment device may also be secured to, or form part of, the hozel or ferrule of the golf club.

Title: Atherectomy power control system
Inventor: HIRST PAUL A
IPC: A61B19/00
Filed: 2000-03-09
Abstract: A power control system maintains the power dissipated by an atherectomy burr during an ablation procedure at or below a predetermined threshold. A power control circuit monitors the speed and torque provided by a prime mover that rotates the ablation burr in order to calculate the power dissipated under no-load conditions. During ablation, the power dissipated is determined and the no-load power is subtracted to calculate the ablation power. The control circuit adjusts the speed of the prime mover to maintain the ablation power at or below the predetermined threshold.

Title: Composite clumping cat litter
Inventor: BLOOMER LARRY D
IPC: A01K1/015
Filed: 2001-06-11
Abstract: An economical process that combines bentonite, or similar clays, that form a clump when in contact with cat urine, with waste cellulosic fibrous materials, preferably paper mill sludge, to form a light weight scoopable (clumping) cat litter product. In the process, paper mill cellulose waste is combined with bentonite clay (preferably sodium bentonite) in a mixing auger in varying percentages depending upon the desired end weight of the finished product, transferred to a secondary rotating drum mixer, then to a rotating drum dryer, and from the dryer to a screening process. The finished product is a granule weighing between 20 lbs./cubic foot and 50 lbs/cubic foot. The granule is highly absorbent and capable of forming a distinct clump that can be separated from the surrounding granules without falling apart. A unique characteristic of the process is the combination of heavy clay particles with light weight cellulose particles to form a new composite particle. In an alternate embodiment of the process of the present invention, the paper mill sludge may be first dried and then run through a hammer mill in order to create a dry, small particle site cellulosic material. These small, dried particles are then dry blended with the bentonite clay. Moisture is then added to aggregate the cellulosic material and the bentonite clay. The resulting aggregate particles may then be shaped, dried and separated as in the process described above.
