Title: Polymerisation a germe en un seul stade destinee aux particules polymeres de dimensions importantes a distribution de taille etroite
Inventor: LARSEN ROLF OLAF
IPC: A61K8/72
Filed: 2000-09-11
Abstract: L'invention concerne des particules polymères sphériques de dimensions importantes à distribution de taille étroite et un procédé de préparation de ces particules. Le procédé de l'invention est caractérisé en ce que l'on effectue la polymérisation à germe dans laquelle les particules de départ possèdent une capacité très élevée d'absorption de nouveaux monomères; de cette manière, les particules finies sont obtenues après un seul stade de polymérisation, même si les particules finies doivent avoir une taille aussi importante que 10 à 100 µm. Le procédé de l'invention est aussi caractérisé en ce que lors de la fabrication d'articles poreux on peut former une structure poreuse dans laquelle la fraction des micropores est insignifiante. Une autre particularité caractéristique du procédé consiste en une distribution étroite de la taille des particules finies; elle est parfois plus étroite que dans les particules de départ.

Title: Thermochromic ink formulations, nail lacquer and methods of use
Inventor: SMALL LYLE D
IPC: B41M5/28
Filed: 1995-09-29
Abstract: The present invention comprises a series of discoveries related to the problems associated with formulations that destroy the color change properties of thermochromic encapsulated dyes. One aspect of the present invention is the discovery of a method of correcting these formulations to allow the addition of thermochromic dyes. Certain solvents destroy the dye, therefore any aldehydes, ketones, and diols, and most aromatic compounds should be removed from the formulation and if needed they should be replaced with solvents preferably having a large molecular weight (i.e. greater than 100 and low reactivity). Secondly, the formulation should be adjusted to be neutral (i.e. 6.5-7.5 pH) or have a low acid value. These two adjustments will allow the thermochromic dyes to be added to the formulation without a loss of its color change properties.

Abstract: L'invention concerne un système de récupération de données pour lien de données numériques en série, comprenant un échantillonneur de données, une logique de comparaison, un contrôleur de phase, et un compensateur de phase. L'échantillonneur de données échantillonne des données d'entrée trois fois dans un temps bit déterminé par les impulsions d'horloge générées par le compensateur de phase, et récupère des données numériques selon un critère de décision prédéterminé. Les phases d'échantillonnage des données sont segmentées de façon à repérer l'oeil des données. La logique de comparaison compare la sortie de l'échantillonneur de données selon un procédé prédéterminé. Le contrôleur de phase utilise la sortie de la logique de comparaison et génère des signaux de commande de phase. Ces signaux sont établis de manière à commander les temps d'échantillonnage de l'échantillonneur de données et obtenir un train de données récupéré de manière presqu'optimale. Le compensateur de phase utilise les signaux de commande de phase et génère trois horloges de phase différente à partir de l'horloge d'entrée. L'horloge d'entrée peut être une horloge externe, ou peut être récupérée de l'horloge externe ou du train de données d'entrée.
Patent CA-2392555-A1 (CA)
Title: Method and apparatus for operating a fuel cell
Inventor: SCHAMM REINHOLD
IPC: H01M8/04
Filed: 2000-12-04
Abstract: The present invention relates to improving the overall efficiency of a fuel cell system by reducing parasitic power consumption. In particular, efficiency is improved by controlling the supply of oxidant to reduce excess oxidant stream flow by operating the fuel cell system with an oxidant stoichiometry between about one and two. A controller is programmed to decrease oxidant stoichiometry until oxidant starvation is detected or until oxidant stoichiometry is about one. When oxidant starvation is detected, the oxidant stoichiometry is increased until oxidant starvation is no longer detected. The fuel cell system employs a sensor for detecting an operational characteristic such as voltage output, or oxygen or hydrogen concentration in the cathode exhaust stream. The controller uses the operational characteristic to calculate oxidant stoichiometry or to determine when there is oxidant starvation at the cathode.

Patent CA-2393717-A1 (CA)
Inventor: HAEFFELE JEFFREY JOHN
IPC: G01R31/317
Filed: 2002-07-17
Abstract: An eye diagram analyzer assigns a plurality of SUT data signals (8) to be members of a labeled group (5) of channels. There may be a plurality (6,7) of such groups. In addition to mere superposition in an (X, Y) display space of the various i-many (X, Y)-valued pixels for individual component eye diagrams associated with that group, other measured data for those pixels within a group can be merged in various different modes (13) to produce corresponding composite eye diagram presentations (11). E.g., in a Normalized Signal Density Mode the number of hits at each trial measurement point is summed over all channels in the group, and then divided by the total number of clock cycles measured for the i th, measurement point in that group to produce a density D i associated with the corresponding i th, pixel: (X i, Y i, D i). If D i is rendered as a color or an intensity, the resulting eye diagram includes a representation (the D i) of a normalized density of transitions at each point (X i, Y i), relative to that group as a whole. As a further example, in a Channel Density Mode, each D i is produced by accumulating, for each of N-many channels, a 1/N for each sample (value of i) with non-zero signal activity, and dividing the accumulation by N. If that collection of D i is rendered as a color or an intensity, the resulting composite eye diagram includes a representation (the D i) at each (X i, Y i) point of the degree of coincidence among, or a degree of similarity between, the channels in the group.

Abstract: An information distribution system distributes information over a distribute d network, e.g. the Internet, in a multi-phase manner. In particular, the information distribution system provides, for example, to an end user, a mod el for determining a particular output (S120). Then, as a user requests the mos t current output of the model (S130), a parameter set is forwarded to the user  (S140) and introduced to the model. This parameter set, with the cooperation  of the model, allows for determining, for example, a current merchants prici ng information for a plurality of goods and/or service (S150). By using this model based approach, the entire set of information need not be distributed to the user every time an update is made. To the contrary, only a sub-set of information, i.e., the parameters, will be forwarded to the user for updatin g of information at a user device.

Abstract: A reel (20) comprises a drum assembly (22) enclosed within a shell comprising upper and lower shell portions (24, 26). The drum assembly (22) is secured to the lower shell portion (26). The drum assembly (22) comprises a motor-driven rotating drum (36) secured between two discs (38, 40), and a frame subassembly (23). The drum (36) is adapted to receive linear material (150) spooled thereon. An outer surface of one of the discs has a spiral groove (88), with a first end (90) near the center of the disc and a second end (92) near an outer edge. The second end (92) is tapered to lesser depth. The frame subassembly (23) includes a track assembly (54) facing the discs with the spiral groove (88) and a translating plate (70) adapted to translate horizontally within the track assembly. As the drum and discs rotate, horizontal pins (76, 78) of the plate (70) alternatingly engage the spiral groove (88), causing the translating plate to translate linearly within the track assembly. The translating plate is connected to and causes the upper shell portion to reciprocatingly rotate about a vertical axis with respect to the lower shell portion and drum assembly. A guide aperture (128) is provided in the upper shell portion, through which linear material (150) is drawn onto the rotating drum (36). Advantageously, the aperture translates through an arc in front of the drum (36), so that the linear material (150) is distributed across the drum surface as it is wound. <IMAGE> <IMAGE>
