A high-voltage cable includes a composite core surrounded by an electrical conductor, wherein it is limited to 95° C.±5%, and the electrical conductor is made of hard aluminum with an aluminum ratio Ra of between 6 and 19, wherein Ra is calculated according to the following rule: Ra=Sc/Sa×100, where Sc is the cross-section of the composite core of the cable and Sa is the cross-section of the conductive aluminum of the cable. This makes it possible to obtain a cable with the same mass as current low-temperature cables, the same external diameter, at least the same mechanical strength and equivalent thermal expansion. This results in a cable in which the aluminum cross-section is increased by between 20% and 40% with the same mass.

A length-adjustable connecting rod is disclosed having a longitudinal axis comprising a connecting-rod shank provided with at least one internal thread, at least one connecting element comprising an external thread cooperating with the internal thread of the connecting-rod shank, the screwing or unscrewing of the connecting-rod shank with respect to the connecting element allowing the length of the connecting rod to be adjusted, and at least one resisting torque device between the connecting-rod shank and the connecting element, the resisting torque device comprising at least one pressing element and a bearing element, the pressing element exerting a force on the bearing element that opposes a resistance to the rotational movement of the connecting-rod shank with respect to said connecting element. The bearing element is integral with the connecting element and the pressing element is integral with the connecting-rod shank.

摘要:
A profiled member having two faces and having at least one tear strip with two edges arranged on and adhered to one face of said profiled member, the tear strip having at least one non-adhered edge. The non-adhered edge makes it possible not only to more easily take hold of and remove the tear strip, but also prevents a piece of the tear strip from remaining on the profile member and hindering the adhering of the profiled members to each other. The two edges of the tear strip may be non-adhered, and, when the profile member is covered by a tear strip on each face, the two tear strips are each non-adhered on at least one side. The profile member can be either flat or circular.
摘要:
The present invention relates to a nonwoven that includes superposed plies of fibers, such that a binder web is positioned between two plies and heat sealed to the at least two plies, and that it is not stitched. The heat sealing of the plies makes the nonwoven extremely solid and sets the orientation of the fibers, which can no longer move during the processing of the nonwoven. The fibers are, in fact, held by weld points that are non-continuous and are distributed over the entire surface, unlike stitching.
摘要:
A process for producing a bonded connection between a first and a second part, with a length of superposition around a longitudinal axis, these parts being subjected to forces in at least one longitudinal direction, includes producing a bonded connection having at least one interior and/or exterior adhesive joint, over a portion of the length between the parts, the joint having a closed or semi-closed cross-section around the longitudinal axis, the thickness of the joint varying from a free edge on the end-fitting side, to the other free edge on the tube side, and following the direction of forces to which the parts are subjected so as to better distribute the overstresses over at least one part of the length. At least one adhesive joint is produced, having in the longitudinal direction a large thickness facing each of its two free edges relative to the thickness in its median part.
摘要:
A main body of doctor blade chambers including a first portion configured to hold a first doctor blade, a second portion configured to hold a second doctor blade, a third portion connecting the first portion and the second portion, a cavity intended to receive ink and defined at least by the first portion, the second portion and the third portion, characterized in that the main body is a single closed hollow profile extending along a longitudinal main axis X-X, the main body being made of pultruded composite material.
