Publication number: 20240052511Abstract: A device for producing a pure metal or an alloy of the pure metal via electrolytic reduction of an ore of the pure metal or of a substance containing an oxidized form of the pure metal includes: a cell equipped with an anode, a cathode, an electrolytic area comprising an electrolyte, and a removable cell closing system, the cathode having a coating non-adherent for an electrolytically deposited metal; and an electrically conductive metal sheet for extraction of a plate of the electrolytically deposited metal on the cathode, the metal sheet being arranged in the cell in a continuation of the cathode or partially overlapping the cathode, with mechanical and electrical contact at one end with the cathode and extending at least partly beyond the electrolytic area of the cell so as to allow simultaneous depositing of the pure metal on the cathode and on a portion of the metal sheet.Type: ApplicationFiled: August 4, 2023Publication date: February 15, 2024Inventors: Andrea BALDINI, Cedric FLANDRE, Luc VANHEE

Patent number: 10171328Abstract: The present invention provides improved methods and devices for managing network congestion. Preferred implementations of the invention allow congestion to be pushed from congestion points in the core of a network to reaction points, which may be edge devices, host devices or components thereof. Preferably, rate limiters shape individual flows of the reaction points that are causing congestion. Parameters of these rate limiters are preferably tuned based on feedback from congestion points, e.g., in the form of backward congestion notification (“BCN”) messages. In some implementations, such BCN messages include congestion change information and at least one instantaneous measure of congestion. The instantaneous measure(s) of congestion may be relative to a threshold of a particular queue and/or relative to a threshold of a buffer that includes a plurality of queues.Type: GrantFiled: June 13, 2014Date of Patent: January 1, 2019Assignee: Cisco Technologies, Inc.Inventors: Davide Bergamasco, Andrea Baldini, Valentina Alaria, Flavio Bonomi, Rong Pan

Patent number: 8238347Abstract: A Data Center Ethernet (“DCE”) network and related methods and device are provided. A DCE network simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet, storage and other traffic. A Fiber Channel (“FC”) frame, including FC addressing information, is encapsulated in an Ethernet frame for transmission on a Data Center Ethernet (“DCE”) network. The Ethernet address fields may indicate that the frame includes an FC frame, e.g., by the use of a predetermined Organization Unique Identifier (“OUI”) code in the D_MAC field, but also include Ethernet addressing information. Accordingly, the encapsulated frames can be forwarded properly by switches in the DCE network whether or not these switches are configured for operation according to the FC protocol. Accordingly, only a subset of Ethernet switches in the DCE network needs to be FC-enabled. Only switches so configured will require an FC Domain_ID.Type: GrantFiled: April 6, 2006Date of Patent: August 7, 2012Assignee: Cisco Technology, Inc.Inventors: Claudio DeSanti, Silvano Gai, Andrea Baldini

Patent number: 7602720Abstract: Novel methods and devices are provided for AQM of input-buffered network devices. Preferred implementations of the invention control overall buffer occupancy while protecting uncongested individual VOQs. The probability of setting a “global drop flag” (which is not necessarily used to trigger packet drops, but may also be used to trigger other AQM responses) may depend, at least in part, on the lesser of a running average of buffer occupancy and instantaneous buffer occupancy. In some preferred embodiments, this probability also depends on the number of active VOQs. Moreover, a global drop flag is set in conjunction with a drop threshold M associated with the VOQs. Whether an AQM response is made may depend on whether a global drop flag has been set and whether a destination VOQ contains M or more packets. Different M values may be established for different classes of traffic, e.g., with higher M values for higher-priority traffic. AQM responses (e.g.Type: GrantFiled: June 16, 2005Date of Patent: October 13, 2009Assignee: Cisco Technology, Inc.Inventors: Davide Bergamasco, Flavio Bonomi, Valentina Alaria, Andrea Baldini
