Abstract
Abstract Device for loading and unloading cargo vessels conveying gaseous, liquid or solid materials, comprising a system of hinged on-shore conduits, selective means for connecting said conduits to stationary conduits of on-shore plants and to conduits of vessel tanks, means for cleaning said hinged on-shore conduits, the number of which is smaller than that of said stationary conduits of on-shore plants and that of conduits of vessel tanks.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
A device for loading gaseous, liquid and fluidized solid materials from on-shore plants into tanks of board vessels and inversely, comprising a system of loading lines intended to connect some of said tanks to some of said on-shore plants, the number of loading lines being smaller than the number of on-shore plants and the number of different materials to be loaded, said on-shore plants comprising a plurality of stationary conduits open at one end and connected at another end to said on-shore plants, said stationary conduits being arranged radially along an arc of circle having a central point, said loading lines comprising each a movable duct pivotably mounted at one end about a vertical axis at the said central point and provided at another end with means for connecting it to one of said stationary conduits, said loading lines further comprising each of a conduit formed by hingedly interconnected duct means movable in vertical and horizontal planes respectively, this latter conduit being connected at one end to the said movable duct at said vertical axis and being provided at an other end with means for connecting it to one of said tanks.
Claim 2
Independent Claim
192 words
A device for loading gaseous, liquid and fluidized solid materials from on-shore plants into tanks of board vessels and inversely, comprising a system of loading lines intended to connect some of said tanks to some of said on-shore plants, the number of loading lines being smaller than the number of on-shore plants and the number of different materials to be loaded, said on-shore plants comprising a plurality of stationary conduits open at one end and connected at another end to said on-shore plants, said stationary conduits being arranged radially along an arc of circle having a central point, said loading lines comprising each a movable duct pivotably mounted at one end about a vertical axis at the said central point and provided at another end with means for connecting it to one of said stationary conduits, said loading lines further comprising each of a conduit formed by hingedly interconnected duct means movable in vertical and horizontal planes respectively, this latter conduit being connected at one end to the said movable duct at said vertical axis and being provided at an other end with means for connecting it to one of said tanks.
Claim 3
Dependent Claim
66 words
A device according to claim 1, wherein each said stationary conduit of on-shore plants comprises a piston movable within the stationary conduit between two positions, one of which allows communication between the stationary conduit and the loading line whereas the other closes the said communication, each loading line comprising means for moving a said piston within a stationary conduit onto which said loading line is connected.
Claim 4
Dependent Claim
49 words
A device according to claim 2, wherein said piston terminates on the side of the open end of the stationary conduit with means for receiving an element intended for cleaning the loading line, and said stationary conduit further comprises means for propelling the said element throughout the loading line.
Claim 5
Dependent Claim
25 words
A device according to claim 3, further comprising means for returning the cleaning element throughout the loading line toward said piston of the stationary conduit.
Claim 6
Dependent Claim
41 words
A device according to claim 1 wherein at least one said movable duct of a loading lines comprises a first duct part pivotable about said vertical axis and a second part pivotably mounted on the first part about a horizontal axis.
