Abstract: The invention relates to a device for reducing the corona effect, which is applicable in particular to connection nodes between conductor tubes of a power substation, which includes an electrically conductive primary filamentous element wound onto itself forming an enveloping figure.

Abstract: The invention addresses an electric connector for the assembly of at least one branch neutral cable (24) into a main neutral cable (26) of the type including a lower body (10) and an upper body (12) both having contact blades, members (20, 22) for accommodating these cables between the two bodies, as well as clamping feature (28), characterized in that it comprises grounding feature (112) in contact with at least one of the blades.

Abstract: A wedge connector provided with an insulating covering, comprising: an external C-shaped member (2), having two first curved wings (10), the respective bottoms (12) of which are mutually inclined; a wedge member (6) having two mutually inclined concave active edges (14); and at least one intermediate member (4) which [i] comprises electrically conducting material; [ii] is adapted to be located between the external member (2) and said wedge member (6); [iii] is provided with a plurality of perforating teeth (22); and [iv] surrounds in part at least one portion of a conductor (20) disposed between the wedge member (6) and the intermediate member (4).

Abstract: The invention addresses an electric connector for the assembly of at least one branch cable (24) into a main cable (26) of the type comprising a lower body (10) and an upper body (12) both having contact blades (18), means (20, 22) for accommodating these cables between the two bodies, as well as clamping means, characterized in that the means (20) for accommodating the branch cable/s (24) comprise a tube having apertures for the passage of the ends of the contact blades (18).

Abstract: A device for molding plastics material ferrules for optical fiber connectors comprises a molding cavity defined by an accurately sized cylindrical bush defining the outside diameter of the ferrule. A cover closes the molding cavity. A peg joined to the cover extends axially into the molding cavity and is extended at its free end by an accurately sized needle defining the inside diameter of the ferrule. A backing member extending axially into the molding cavity from the opposite end as compared with the peg comprises a bore for guiding the needle adapted to receive the end thereof when the backing member moves towards the peg so as to render the needle and the bush concentric. A venting system allows gases to escape from the molding cavity to the exterior when plastics material is injected into the mold. The backing member is a substantially cylindrical body of revolution which fits directly into the bush with no clearance and minimal force.

Abstract: This invention relates to a process for measurement of the relative positions of the center-lines of an aperture and of a cylindrical outline of a sample.The process includes the following steps:introducing a calibrated rod into said aperture;performing measurements to define at least a pair of segments representative of the mid-points of the cylindrical outline and of a calibrated rod respectively.The measurements are performed utilizing a light beam which is scanned parallel to the beam in a direction perpendicular to the center-line of the cylindrical outline. This enables measurement of the coaxiality and/or of the concentricity of the center-line of the outline and of the aperture.

Abstract: A device for measuring the thermal expansion of a sample comprises a measurement radiation generator, a base member incorporating a reference groove and a furnace. The furnace has an external reference contour adapted to cooperate with the reference groove, an internal reference contour adapted to cooperate with a sample and an aperture through which the measurement radiation passes.
