Title: Polymerisation and/or crosslinking method under electron beam and/or gamma radiation
Inventor: PRIOU CHRISTIAN
IPC: C09D201/00
Filed: 1999-08-02
Abstract: The invention concerns a polymerization and/or crosslinking method under electron beam and/or gamma radiation for compositions based on monomers, oligomers and/or polymers with organic functional groups. The invention is characterized in that the crosslinking and/or polymerization is carried out in the presence of an initiator capable of being activated under electron beam and/or gamma radiation comprising a boron derivative of formula (I) M+B(Ar) 4wherein: M+, a unit bearing a positive charge, is an alkaline metal selected among those of columns IA and IIA of the periodic table; Ar is an aromatic derivative, optionally substituted by at least a substituent selected among a fluorine radical, a chlorine radical, a linear or branched alkyl chain, which itself can be substituted by at least a fluorine atom.
Patent CA-2340184-A1 (CA)
Inventor: KUSHNIR ORL BARUCH
IPC: H04L12/851
Filed: 2000-06-26
Abstract: A method and apparatus for reconstructing sessions on a network is described.  The method allows for monitoring of quality of service at an application level as well as for understanding application specific events. This allows the method to be used to generate service detail records for usage based on application type for use in billing. It also allows the qualitative and quantitative analysis of quality of service based on application specific parameters. For example, for web applications, quality of service can be measured by the time from requesting a link till the close of the session by delivery of the whole page. Similarly, for voice over IP calls, application events like adding participants and removing participants can be detected and billed accordingly. Also, the quality of service can be measured. For example, the actual latency can be compared to a predetermined latency amount set by a provider for voice over IP calls. Additionally, service detail records can be generated based on application specific events instead of generic flows, so usage billing can be performed based on factors such as a price per minute per leg, etc., with application specific events generated each time a leg is added or dropped. Further, because the periodicity of the output can be controlled on a per application basis, output for voice over IP calls can be generated more often than for other applications. Additionally, embodiments of the invention can reconstruct sessions that are flowing across multiple network devices.

Title: Soap dispensing mechanism
Inventor: GREGORY JACK T
IPC: A46B11/06
Filed: 2000-08-03
Abstract: Dispensing valve unit (12) has a stationary inner tubular assembly (22), a telescopically shiftable outer tubular assembly (24) and an inner dual valve assembly. Inner assembly (22) has a soap entry port (54), whereas outer assembly (24) has an opening (92) registrable with port (54). A cam mechanism (40, 80) effects axial shifting of outer assembly (24) relative to inner assembly (22) upon rotation. Outer assembly (24) is shiftable so that unit (12) may assume three different positions: a soap and low low volume water delivery position wherein opening (92) is in registry with port (54) so that soap is drawn from an annular reservoir (112), and valve body (26) is shifted to permit controlled water flow therethrough so that soap and water are mixed for dispensing; a high volume water-only rinse position where valve body (26) is shifted from shoulder (48) and portion (90) covers the port (54); and an all-off position where valve body (26) engages shoulder (48) and prevents water flow through the valve body (26), and the portion (90) covers the port (54).

Title: Moteur electrique
Inventor: HOBSON BARRY REGINALD
IPC: H02K1/22
Filed: 1999-11-12
Abstract: L'invention concerne un moteur (10) électrique qui comprend un aimant (12) se présentant sous forme d'un anneau de Cockcroft comportant un entrefer (18) périphérique traversé par des lignes de flux magnétique. Ce moteur comprend en outre un disque (14) planaire capable d'effectuer un mouvement bidimensionnel par rapport à l'aimant (12). Ce disque (14) comprend un certain nombre de voies (C) conductrices d'électricité dont chacune comporte un segment (16) qui recoupe les lignes de flux magnétique dans l'entrefer (18). Un transformateur (40) polyphasé comprenant plusieurs ouvertures (42) est disposé de telle manière que chacune des voies (C) est connectée à au moins une des ouvertures (42). Le transformateur (40) polyphasé entraîne le passage des courants dans les voies (C) conductrices respectives, à travers les segments (16) respectifs de chaque voie (C). L'interaction du courant passant dans les segments (16) avec les lignes de flux magnétique passant à travers l'ouverture (18) provoque une force de poussée qui s'exerce sur le disque (14) dans une direction conforme au sens trigonométrique. L'amplitude et la direction des forces de poussée respectives et, partant, le mouvement du disque (14) sont réglés par la variation de l'amplitude et/ou du rapport de phase des courants passant à travers les segments (16). Ce système permet de régler le mouvement du disque (14) sur n'importe quelle trajectoire bidimensionnelle.

Abstract: To provide a technique for measuring characteristics such as chromatic dispersion and the like, by making it possible to continuously sweep the wavelength of light source.        The present invention comprises a variable-wavelength light source 12 for generating a variable-wavelength light, wavelength of which is variable, having an identification waveform at the time when the wavelength is changing, wherein the identification waveform is distinguishable from a normal waveform before and after the time when the wavelength is changing; an optical modulator 14 for modulating the variable-wavelength light to a predetermined frequency and casting it on an optical fiber 30; and an identification waveform detection section 24 for detecting the identification waveform in a light transmitted through the optical fiber 30, wherein since the time t0 that the identification waveform detection section 24 detects the identification waveform is the time when the waveform starts to change, it is possible to obtain a synchronization of incidence side and exit side of optical fiber 30 using the t0. Accordingly, it is possible to obtain the synchronization of incidence side and exit side of device-under-test even if the wavelength of light source is continuously swept, whereby characteristics such as chromatic dispersion and the like can be measured.
