20100214957Method for network design to maximize difference of revenue and network cost - A method determines an optimal or near-optimal conveyance network layout in which revenue from serviced customer locations is maximized while the cost of installing and/or maintaining the conveyance is minimized. The conveyance may, for example, be a fiber optic telecommunications cable or a power or utility distribution system. Algorithms in the method generate primal and dual bounds in a Prize-Collecting Steiner Tree Problem in Graphs (PCSPG). Those algorithms originate from a Lagrangian Non-Delayed Relax-and-Cut (NDRC) based approach and incorporate ingredients such as a new PCSPG reduction test, an effective Local Search procedure and a modification in the NDRC framework that allows additional reductions in duality gaps to be attained.08-26-2010

20090277908CLOSURE ARRANGEMENT FOR A CONTAINER - The closure arrangement is applied to a metallic container comprising a peripheral side wall which presents an upper edge surrounding an opening, in which is fitted a lid having a peripheral upper wall externally provided with a circumferential rib to be fitted in an inner circumferential recess of the peripheral side wall; and a circumferential groove located inferiorly to the circumferential rib and housing a sealing ring to be internally seated against the peripheral side wall upon the fitting and axial retention of the circumferential rib in the circumferential recess.11-12-2009
20100127003SUSPENSION DEVICE FOR CONTAINERS - A suspension device is applied to containers comprising a tubular body (05-27-2010
20100300916CONTAINER FOR PRESSURIZED FLUIDS - A container having a tubular body including a side wall, a bottom wall in the form of a spherical dome projecting to the interior of the container, and an upper wall in the form of an annular spherical dome, inferiorly attached to the side wall by an upper double seam. The bottom wall includes at least one seating region having a predetermined circumferential extension along a plane extending transversely with respect to an axis of the container and being axially spaced inwardly within the side wall of the container, the seating region being configured to be fitted around a respective circumferential extension a upper double seam of an identical and adjacent container inferiorly disposed in a vertical stack, and axially seated on said upper double seam, so as to define a single contact region between two vertically stacked containers.12-02-2010
20110210129CONTAINER IN METAL SHEET - The container includes a peripheral side wall, whose upper peripheral edge defines a retention hook with a profile in the form of an inverted U, having an inner side leg, an arched base leg (lib) and an outer lateral leg (lie). An upper end wall of the container includes a median panel and a peripheral upper skirt having an end edge defining a closure hook with a profile in the form of an inverted U, having an inner side portion, an arched base portion, and an outer side portion which incorporates an upwardly projecting end flange. The closure hook is fitted onto the retention hook and radially inwardly deformed, compressing an elastic sealing element between the two hooks and maintaining the end flange projecting upwardly to the interior of the retention hook.09-01-2011
20110299959PROCESS FOR CLOSING A CONTAINER IN METAL SHEET - The container has a tubular body having a peripheral lateral wall provided with an upper end portion and a lower end portion defining an upper retention hook and a lower retention hook to which is double-seamed a lower end wall. An upper end wall is conformed to incorporate a peripheral upper skirt presenting an end edge defining an inverted U shaped upper closure hook to be seated onto the upper retention hook sandwiching an elastic sealing element therebetween. The upper closure hook and the upper retention hook and also a portion of the peripheral upper skirt and a confronting region of the upper end portion are deformed for seaming the upper closure hook onto the upper retention hook and to form, respectively, a retention rib and a retention groove which tightly fits the retention rib.12-08-2011
