Title: Procede et systeme de comptabilite de sessions dans des reseaux sans fil
Inventor: JONES MARK
IPC: H04W4/24
Filed: 2002-09-30
Abstract: Les services de données sans fil, tels que le courrier électronique sans fil, se généralisent, et notamment les systèmes à connexion permanente, dans lesquels le nouveau message de courrier électronique est retransmis automatiquement par le fournisseur de services au dispositif sans fil. Cependant, le problème réside dans le fait qu'il n'existe pas de mécanisme efficace d'exécution pour mettre en oeuvre ces systèmes à connexion permanente lorsque l'utilisateur navigue dans un réseau, ou d'un réseau à un autre. Ce problème est résolu par le système et le procédé de l'invention qui permettent de générer une clé de session au niveau du système fournisseur de services pour une certaine session de données et de renvoyer cette clé de session au dispositif mobile. Chaque fois que le dispositif communique avec le fournisseur de services, ladite clé de session est introduite dans un champ et traverse le réseau de communications jusqu'au fournisseur de services. Cela permet au fournisseur de services de gérer la session de données, de préparer des documents comptables appropriés et de diriger, sur les ressources du réseau, la radiation des sessions de données dépassées.

Abstract: DRIVING TOOL WITH AIR-COOLED BUMPER                     ABSTRACT        A driving tool comprising a cylinder, a piston movable axially within the cylinder, a driving element movable conjointly with the piston so as to move through a central aperture of an end wall of the cylinder in a driving stroke and in a return stroke, and a bumper, which arrests movement of the piston toward the end wall of the cylinder in a driving stroke.  The bumper is made of resilient material, such as a cast polyurethane, in an annular shape. The bumper has a plurality of slots extending radially from each of its inner and outer peripheral surfaces and extending axially between its opposite ends.  Each of a plurality of ports in a wall of the cylinder, either the end wall or a cylindrical wall, communicates with a space between the piston and the end wall and with one of the slots to cause air to pass through the communicating slots before being exhausted through the ports in a driving stroke and after being admitted through the ports in a return stroke.  Air passing through the communicating slots helps to cool the bumper.

Abstract: With a turbine of the present invention, a preferably spiral partition is formed upright on the outer periphery of a rotor carried rotatably in a casing.  A large number of blades are mounted between turns of the partition at a predetermined interval on the  outer periphery of the rotor, and a channel for the working fluid is formed in the space between the blades and the partition on the outer periphery of the rotor.  Therefore, the turbine of the present invention is a highly efficient turbine capable of efficiently utilizing even a low pressure low speed low flow rate working fluid, while being capable of efficiently converting the kinetic energy of the working fluid into the rotational force of the rotor and realizing a low speed high torque rotation.   A turbocharger  making  use  of  the  turbine  is  capable  of performing sufficient supercharging not only during high speed rotation but during low speed rotation of the engine, while being preferably capable of cleaning emission gases.

Filed: 1990-12-12
Abstract: This is an improved process for producing an optically active atenolol useful as a .beta.-adrenergic blocker for the treatment of angina pectoris, arrhythmia and hypertension.          In this process a phenol compound is reacted with an optically active epihalohydrin to give an intermediate, optically active glycidyl ether compound.  The intermediate is then reacted with isopropylamine.  Purification of the optically active atenolol in high yield is achieved by forming a salt of atenolol with a Br~nsted's acid.  The salt of optically active atenolol having high optical purity can be separated from the salt of racemic atenolol by a solid-liquid separation method.
