Abstract: La présente invention concerne un régime alimentaire, une combinaison unique de compléments nutritionnels, ainsi qu'un procédé faisant appel à ces derniers. Cette invention concerne plus précisément une combinaison unique de compléments nutritionnels qui permet de soulager les symptômes de l'arthrite. Cette combinaison unique de compléments nutritionnels permet d'accroître le niveau efficace d'agents anti-inflammatoires disponibles dans le sang, ainsi que de favoriser le processus de cicatrisation/régénération des articulations atteintes, ce qui permet d'obtenir un soulagement symptomatique étonnant et durable en ce qui concerne les effets débilitants tant de l'arthrose que de la polyarthrite rhumatoïde. Les compléments nutritionnels essentiels de ce régime comprennent les éléments suivants: (a) un acide linoléique gamma non raffiné, appelé "GLA"; un mélange d'acide eicosapentanoïque et d'acide docosahexanoïque, appelé "EPA"; et (c) un mélange de sulfate de chondroïtine, de sulfate de N-acétyle glucosamine, de sulfate de glucosamine et d'aspartate de manganèse appelé "CHONDROX". Ce régime est adapté en fonction du poids de la personne qui, une fois le soulagement symptomatique obtenu, ne souffre pratiquement plus des effets débilitants de l'arthrite pour autant que le régime quotidien soit observé scrupuleusement.

Abstract: A saw chain of a chain saw has its side links and center links interconnected by rivets. Prior to being staked, each rivet is in blank form and includes a cylindrical flange and a pair of barrels extending from opposite sides of the flange along a center axis thereof. Each barrel includes an axially inner cylindrical section and a tapered axially outer section. When the rivet is staked, the center section of each barrel fills a cylindrical portion of a hole formed in a respective side link, and the tapered section fills a chamfered portion of the hole to form a rivet head. The staked rivet bears against a wall of the cylindrical portion of the hole with a greater force than that with which the rivet bears against a wall of the tapered portion of the hole.

Title: Marking and screening telephone calls
Inventor: HOLIDAY MATTHEW R II
IPC: H04M3/436
Filed: 1998-12-09
Abstract: A system and method that controls calls, such as telephone solicitations, by a calling party to a called party. A switch receives a call from the calling party and marks the call to identify it as a telephone solicitation. Such marking can be performed in various ways, such as altering a forward call indicator of an IAM message if the switch is using an ISUP procedure, or providing a station type with information digits used in multi-frequency signaling. After the call has been marked, it can then be identified by a switch serving the called party as a telephone solicitation. Once identified, the switch then analyzes a profile for the called party and determines how to complete the call. For example, if the profile indicates that the called party does not want to receive telephone solicitations, the call will not be completed to the called party, but instead will receive alternate treatment.

IPC: H04L12/933
Filed: 1999-04-01
Abstract: The present invention relates to a method and related device to be used to establish a traffic based shortcut when running the Internet Protocol (IP) over a connection oriented network. Such a network may exists of a number of switch-routers and/or one or more IP-routers and/or one or more switches. The shortcutting is performed by the co-operation of the present IP-routers and or IP-router-parts. The described configuration manages the forwarding of Internet Protocol packet flows along a shortcut path. For each shortcut path set-up, a separate virtual channel connection is used. Only a restricted number of virtual channels is available for shortcut paths to be set up. To improve the efficiency of use of the available virtual channels, the time-out period of a shortcut path is determined depending on the local network load. By maintaining and using, an existing shortcut path to forward one or more IP packet flows simultaneously with, or subsequently to the first shortcutted flow the efficiency is increased as well.
