Title: Procede d'essai et aide visuelle correspondante
Inventor: IRONS PETER
IPC: A61F9/007
Filed: 2000-07-17
Abstract: L'invention concerne un procédé d'essai applicable à la fourniture d'une aide visuelle, par exemple un transparent en plastique teinté à placer sur le texte à lire, ou la sélection d'une teinte pour un écran d'affichage, afin d'améliorer les symptômes en dyslexie et autres troubles optiques connexes. Le procédé se fonde sur une approche quantitative de l'identification du paramètre colorimétrique dans les trois dimensions de l'espace de couleur applicable à l'aide visuelle aux fins d'une performance visuelle optimale. L'invention traite d'une procédure d'essai dans laquelle une valeur numérique (la valeur avantage) est associée à une valeur donnée de chacun des trois paramètres colorimétriques, ainsi qu'une brève série d'essais sur différents paramètres colorimétriques permet d'interpréter la valeur optimale, laquelle peut très bien ne pas être une valeur effectivement testée. Les tâches d'essai sont rigoureusement séparées en tâches matricielles et tâches non matricielles.

Patent CA-2381547-A1 (CA)
Inventor: KNIGHTS SHANNA D
IPC: H01M8/04
Filed: 2000-08-23
Abstract: In a solid polymer fuel cell series, various circumstances can result in a fuel cell being driven into voltage reversal by other cells in the series stack. For instance, cell voltage reversal can occur if that cell receives a n inadequate supply of fuel (for example, fuel starvation). In order to pass current during fuel starvation, reactions other than fuel oxidation may take  place at the fuel cell anode, including water electrolysis and oxidation of anode components. The latter may result in significant degradation of the anode. Such fuel cells can be made more tolerant to cell reversal by promoti ng water electrolysis over anode component oxidation at the anode. This can be accomplished by enhancing the presence of water in the anode catalyst layer through modifications to the anode structure or anode composition near or in  the catalyst layer. For instance, water electrolysis during voltage reversal  is promoted through the use of different or additional ionomer, polytetrafluoroethylene, or graphite in the anode catalyst layer, or through  the use of certain sublayers between the anode catalyst layer and the anode substrate.

IPC: H04L12/56
Filed: 2001-04-03
Abstract: A method for the fair and efficient transfer of variable length packets using fixed length "segments" utilizes a modified UTOPIA interface (12) with three additional signals (14,16,18) added, i.e. start of packet (SOP), end of packet (EOP), and most significant byte (MSB). Packets are broken into "segments" of fixed length. The start of a segment is marked by a pulse on the UTOPIA start of cell (SOC) signal line. The start of a packet is marked by a pulse on the SOP signal line (14). The end of a packet is marked by a pulse on the EOP  signal line (16). When a packet ends with a single byte on the bus, the MSB  signal line (18) is asserted to distinguish it from a packet which ends with two bytes on the bus. The invention can be expanded to accommodate buses wider than 16-bits by making the EOP a multiple bit signal.

Title: Method of welding three-dimensional structure and apparatus for use in such method
Inventor: MEGA MASAHIKO
IPC: B23K26/21
Filed: 2002-09-17
Abstract: When a three-dimensional structure is formed by welding a plurality of members, accurate welding can be performed matching the three-dimensional shape. The teaching data consisting of the three-dimensional position at each of the welding points determined on each of the welding lines at a predetermined spacing on the basis of the design data of the three-dimensional structure is stored in a memory 18. A laser slit light sensor( a laser slit light emitting section 12 and a CD camera 13) is controlled by a total controller 17 via a camera controller 14 to photograph the welding point in order to obtain the image data of the welding point. An image processing apparatus 16 processes the image data to determine the amount of deviation from the design data of welding points. The total controller modify the teaching data on the basis of the amount of deviation from the design data of welding points to establish the modified teaching data and controls a welding head so that it moves according to the modified teaching data.

Abstract: A bolt retainer mechanism in one layer of a multiple-layered steel (MLS) gasket, includes an aperture defining a radially inwardly extending tabs. In one embodiment, each tab is formed to define are inverted U-shaped tang positioned adjacent to, and in symmetrical registration with though axially spaced from, an associated mated aperture formed in a second layer of at least a two-layer gasket. Collectively, the plurality of tangs defines a circumscribed diameter slightly smaller than the diameter of the associated mated aperture, to assure retention of a bolt supported through the mated apertures for pre-assembly shipment. Preferably, the tangs in association with each of the mated apertures are formed of a spring metal adapted to provide radially inwardly directed forces against threaded shanks of associated bolts. To enhance effectiveness of bolt retention, the bolt-contacting portion of each U-shaped tab has an axial length greater than the axial thickness of the apertures.

Title: Disposable cup with fold-down lid
Inventor: KLEYNHANS GREGORY JOHN
IPC: B65D3/28
Filed: 2002-11-22
Abstract: The cup has a lid portion extending up from one side of the cup, configured to flip down into the body of the cup, along a first score line, going from convex to concave, so as to close the otherwise open top of the cup. Flaps extend preferably from the lid portion near its lateral intersections with the cup body outwardly from the cup, or alternatively from the cup body in the same area, but inwardly. In either case, the flaps overlie what might otherwise be a small gap between the lid and the cup body in that area. This reduces any possibility for liquid to escape via that small gap. In the case of the flaps extending outwardly from the lid, the flaps also tend to act as stops against excessive downward rotation of the lid, and provide an easy way to lift the lid to open the cup, if desired. The cup preferably but not necessarily has two secondary fold lines extending from the first score line to the outer edge of the lid portion, near opposite sides of the lid portion, which assists in holding the lid down once closed.
