Title: Method for controlling the extension of an oligonucleotide
Inventor: KURN NURITH
IPC: C12Q1/6848
Filed: 1999-12-10
Granted: 2010-10-12
Abstract: The present invention relates to a method for selectively ex-tending an oligonucleotide primer along a specific target polynu-cleotide sequence in a mixture of polynucleotides. A combina-tion is provided comprising the mixture, an oligonucleotide primer having a modification, and a binding substance for the modifica-tion wherein the binding substance binds to the oligonucleotide and prevents the extension of the oligonucleotide along the target polynucleotide sequence. The temperature of the combination is adjusted to a level sufficient to irreversibly denature the binding substance and permit the extension of the oligonucleotide primer along the specific target polynucleotide sequence. The invention has particular application in the amplification of nucleic acids. Also disclosed are kits for carrying out a method in accordance with the present invention.

Title: Mobile internet access
Inventor: JOKELA PETRI
IPC: H04L12/56
Filed: 2000-05-31
Granted: 2009-11-24
Abstract: A method of authorising an Internet Protocol (IP) enabled mobile host (1) to access the Internet (2) via a wireless LAN, GSM, or UMTS  access network (3) comprises initially sending an IP access request from the mobile host (1) to an IP  router (5) within the access network (3). In response to receipt of said access request at the IP router (5), an IP  address routing prefix is sent from the IP router (5) to the mobile host (1). Electronic cash is then forwarded from the mobile hose (1) to a control point (6) within the access network (3). The control point (6) confirms the authenticity and/or sufficiency of the electronic cash and, providing that confirmation is made, sends an authorisation message to the IP router (5). The IP router (5) blocks the transmission of IP packets between the mobile host (1) and the Internet (2) prior to receipt of the authorisation message and permits the passage of IP packets only after an authorisation message has been received.

Patent CA-2383495-C (CA)
Inventor: JONES MATTHEW BRYANT
IPC: A01B63/32
Filed: 2002-04-24
Granted: 2005-11-15
Abstract: A trailing attachment for a deep tillage implement is supported from the implement frame by transversely spaced four-bar linkages extending rearwardly from the frame. Single acting hydraulic cylinders are pressurized to lift and adjust the attachment. A breather plug and a U-shaped hose allow air to be pushed from the rod end as each cylinder extends. To lower the trailing attachment, an SCV is moved to open the base ends of the cylinders to the return line of the hydraulic system, and the weight of the attachment moves the tools into ground engagement. If vertical lifting force exceeds attachment weight during operation, air is pushed out through the breather plug and a vacuum is drawn in the base ends so the attachment can lift to avoid excessive forces, even if the SCV is in neutral and blocking fluid flow into the base ends.

Abstract: A method of drying lignocellulosic fibrous material in two steps in connection with the manufacture of fiberboard.  The material is transported with the help of a first drying gas through a first drying line (11) to a first cyclone (13) where the first drying gas is conducted away from the material. Thereafter the material is transported with the help to a second drying gas through a second drying line (17) of a second cyclone (19) where the second drying gas is conducted away while the material is advanced to a subsequent step. The second drying gas, which is conducted away from the second cyclone (19), is moved to the first drying step and used as a portion of the first drying gas. A portion of the first drying gas, which is conducted away from the first cyclone (13), is reclycled and used as drying gas at the first drying step.

Abstract: A call centre associated with an intelligent network has no service-specific executable application software running on its operator positions. Instead, each computer stores a set of templates which define respective screen displays, including text display areas and text input areas, and also a set of corporate logos. When an intelligent peripheral of the network is not able to proceed with a call in accordance with an application, a failure notification is sent to the network, which reroutes, i.e.  connects, that call to the call centre and sends a message including an identifier for template to be used by an operator position in generating a screen display.  The operator interacts with the customer, obtains information and enters this in the text entry areas, sends a return message to the network, which then sends a message containing an identifier for a template to be used for the next stage of that application.

Granted: 2009-06-16
Abstract: Un dispositif d'échantillonnage caractérisé par un échantillonneur permettant d'obtenir des échantillons de produit liquide à partir d'un corps de produit dans un récipient. L'échantillonneur comprend un piston ayant un évidement pour la réception de l'échantillon et un dispositif de connexion apparie l'échantillonneur au récipient à une ouverture m du récipient. L'échantillonneur est relié au dispositif de connexion et le dispositif de connexion peut se déplacer entre une première position plaçant l'échantillonneur dans la communication avec l'ouverture, et une seconde position retirant l'échantillonneur de la communication avec l'ouverture. Avec le dispositif de connexion dans la première position, le piston effectue un mouvement alternatif pour étendre le piston et son évidement à travers le dispositif de connexion et l'ouverture du récipient dans un produit dans le récipient pour recevoir un échantillon de produit dans l'évidement. Le piston est ensuite retiré du récipient et à travers le dispositif de connexion pour fournir l'échantillon de produit à un point de collecte. Pendant le mouvement alternatif du piston, un joint d'étanchéité liquide est maintenu entre l'intérieur du récipient et le point de prélèvement de l'échantillon, et lorsque le dispositif de connexion est déplacé à la seconde position, l'échantillonneur peut être détaché du dispositif de connexion pour l'entretien ou la réparation, sans fuite de liquide à partir du récipient par l'intermédiaire du dispositif de connexion. Avantageusement, l'échantillonneur reste stationnaire pendant le mouvement du dispositif de connexion entre les première et seconde positions, de sorte que l'espace supplémentaire pour permettre le mouvement de l'échantillonneur n'est pas nécessaire lors de la fixation de l'échantillonneur et du dispositif de connexion au récipient.
