Abstract: Selon cette invention, un gel en plaque destiné à un appareil d'électrophorèse (12) comprend une paire de plaquettes opposées (14, 16), espacées l'une de l'autre et définissant une zone de séparation (22) à plusieurs voies, cette dernière étant conçue pour contenir un substrat de séparation ou un gel (23), ainsi qu'une zone supérieure de chargement. Au moins une des plaquettes est configurée pour former une zone de chargement élargie (16a-d). La distance entre les plaquettes à l'intérieur de la zone de chargement élargie est plus grande que dans la zone de séparation. Un peigne (24) possède des dents (28) dont chacune s'effile graduellement depuis un élément de support (32) sur presque toute la longueur de la dent. L'effilement de la dent est plus abrupt entre la partie à effilement graduel et le bout de la dent. On insère le peigne dans la zone de chargement de manière à ce que les dents pénètrent dans une partie supérieure du gel formant ainsi une série d'ouvertures allongées, étanches aux fluides et servant au chargement d'échantillons; ils ont une coupe sensiblement rectangulaire et sont plus larges entre les plaquettes que dans la zone de séparation. Cela permet de faire fonctionner 96 voies, même avec des gels ultraminces.

Title: Internet access method
Inventor: VAN DOORSELAER BART ALFONS PET
IPC: H04L12/56
Filed: 1999-12-15
Abstract: Subject of the present invention is a method and a related device used to access an internet network. The network contains at least two hosts, coupled to this network, a first and a second host. Besides these hosts there is a name system and an access node, both connected to the Internet network. If the first host wants to contact the second host, this first host will request the name system for the Internet address. The name system will search, based on the host name of the second host for the Internet address of this host. If this second host is not active, the present invention facilitates that the name server requests the access node to establish a connection between this access node and the second host. The access node will also assign then an internet address to this second host.  Subsequently the access node will forward the assigned internet address of the second host to the name system which on its turn will forward the assigned internet address to the requesting, first host. Now, by using the assigned internet address, the first host is able to contact the second host.

Title: System and method for least cost call routing
Inventor: POKRESS MATTHEW C
IPC: H04Q3/00
Filed: 1998-07-24
Abstract: A least cost call routing system operates in conjunction with one or more telephones (12a, 12b) disposed in a location to provide least cost telephone call routing using a selected one of a number of commercial telephone carriers (18a, 18b, 18c). A central server (48) stores a plurality of telecommunications carriers and associated billing rates.

Patent CA-2305793-A1 (CA)
Title: Search device for locating buried persons
Inventor: ECKHARD CHRISTIAN
IPC: A63B29/02
Filed: 1999-07-30
Abstract: Search devices fitted with only one send and receive antenna do not enable buried persons to be found in a quick and reliable manner because the strongest signals can only be detected at extremely short distances when the antennae of the transmitter and reception devices are placed in a parallel position. The invention uses four antennae in order to pinpoint the exact position of the transmitter, especially at a clue distance. The four antennae form two pairs of antennae placed at a specific angle to each other. The pairs of antennae are respectively comprised of two antennae that are also placed at a specific angle to each other. The direction of the field line of the send antenna can be detected by comparing the signal intensities of the antenna pairs. Lateral deviations and forward or rear deviations from the shortest distance point can be recognised by comparing the signal intenisties of the corresponding antennae. All signals have the same intensity at this point. Search devices are mainly used by wilderness skiers and those choosing to ski off piste.

Patent CA-2314599-A1 (CA)
Inventor: BALSEVICH J JOHN
IPC: A01C1/00
Filed: 2000-07-27
Abstract: Seeds of Brassica's and related species (Crucifers), having increased dormancy coupled with greater tolerance to stresses associated with fall seeding in long winter climates, are produced by treatment with solutions of sugars and/or polyols, for a specified period, typically 10 to 70h at room termperature, followed by air drying to ambient moisture content. Dormancy is generally released on overwintering, moist chilling or hydration-dehydration-rehydration or as a function of increasing temperature or time or a combination of the preceding. Treated seeds afford better emergence over a larger seeding window for fall sown seeds of Brassicas and related species thus increasing the attractiveness of this practice for these crops.
