Patent number: 7730747Abstract: A method and device for vaporizing a liquid reactant. A vaporizing plate having a top surface defines a liquid flow channel, the channel being laterally delimited by edges having a height greater than a minimum thickness of liquid reactant required to generate vapor under film or nucleate boiling regime. A heating system is associated to the vaporizing plate for heating the liquid reactant over a minimum temperature required to generate vapor under nucleate or, preferably, film boiling regime. A cap covers the vaporizing plate to collect the vapor at a predetermined pressure and provided with a vapor exit and a liquid feeder feeds the liquid reactant onto the vaporizing plate.Type: GrantFiled: June 28, 2002Date of Patent: June 8, 2010Assignee: Prysmian Cavi E Sistemi Energia S.R.L.Inventors: Marco Galante, Marco Arimondi, Giacomo Stefano Roba, Ilenia Santi

Publication number: 20070217581Abstract: The present invention discloses a system and method for implementing prepaid data services in a mobile communication network. In this system, a Data service Access Control Point (DACP), which is used for fulfilling price confirmation function and fee application function for data services, is added between a Service Control Point (SCP) storing prepaid account information of subscribers and a Prepaid Server/Content of Process Gateway (PPS/CP GW) used for data service charging. In the method of the present invention, by means of the interaction among a Packet Data Service Note (PDSN), a Home Authentication Authorization and Accounting (HAAA) server, the PPS/CP GW, the DACP and the SCP, the SCP deducts the fees from the prepaid account, and the PDSN controls the subscriber to utilize data service according to the fees deducted by the SCP.Type: ApplicationFiled: July 1, 2004Publication date: September 20, 2007Inventors: Guojun Dai, Stefano Solinas, Franco Veronelli, Marco Arimondi

Patent number: 7212716Abstract: An intermediate polymer preform of elongated shape for manufacturing a microstructured optical fibre is made from a mould with a tubular par containing a pattern of hole generating elements (wires, rods or tubes) extending along it. The hole generating elements are releasably attached to an upper and to a lower base of the mould. The mould is cleaned by circulating a filtered solvent in it. The mould is filled with a fluid polymer optical material or polymer precursor. The polymer material or precursor is consolidated so that it cannot change its shape under operating stress conditions at ambient temperature. The hole generating elements are released from the upper and lower base. The consolidated core preform is extracted from the mould. The process can further include calibrating the intermediate preform.Type: GrantFiled: April 16, 2002Date of Patent: May 1, 2007Assignee: Prysmian Cavi E Sistemi Energia S.R.L.Inventors: Marco Arimondi, Andrea Macchetta, Daniela Asnaghi, Anna Castaldo

Publication number: 20070062337Abstract: A method of producing a preform for a holey optical fiber having at least one hole longitudinally extending therethrough. A porous preform, such as a glass soot preform, is formed by means of flame hydrolysis, or a gel preform; at least one hole is then formed by drilling the porous preform, the hole extending through the porous preform along the longitudinal direction thereof. A holey fiber can be produced by drawing the holey porous preform, after having submitted it to a consolidation process.Type: ApplicationFiled: June 30, 2003Publication date: March 22, 2007Inventors: Guojun Dai, Stefano Solinas, Franco Veronelli, Marco Arimondi

Patent number: 6672110Abstract: A method for manufacturing a glass preform includes supplying a first gaseous or vapor phase composition to a reaction chamber; supplying water as a second gaseous or vapor phase composition to the reaction chamber; reacting the water and the first gaseous or vapor phase composition to form an aerosol of glass particles; directing the aerosol along the reaction chamber, out of the reaction chamber, and toward a target; and depositing glass particles of the aerosol onto the target. The first gaseous or vapor phase composition is disposed to provide a hydrolyzable glass precursor. Walls of the reaction chamber have a temperature gradient in which a temperature of the walls increases in a direction of flow of the aerosol along the reaction chamber. Alternatively, a flow of the aerosol along the reaction chamber has a temperature gradient in which a temperature of the aerosol increases in the direction of flow.Type: GrantFiled: December 16, 1999Date of Patent: January 6, 2004Assignee: Pirelli Cavi E Sistemi S.p.A.Inventors: Giacomo Stefano Roba, Marco Arimondi, Donata Piccolo, Sabrina Fogliani
