Abstract:
The invention relates to a rubber tire composed of carbon black reinforced rubber carcass and having a rubber tread which is composed of a unitary, co-extrusion of tread cap, base and miniwings and, wherein a portion of the miniwings extend as a thin layer over a portion of the tread cap's outer surface to create a path of reduced electrical resistivity.
Abstract:
The device assures an electrical and mechanical connection between two bare sections of electric cables by clamping these sections together. The device comprises two distinct elements that can be assembled together to form a ring surrounding the two bare cable sections, and means for clamping together the sections disposed at the interior of this ring. The two elements comprise relatively thick plates curved in the form of U''s of the same width, and the ends of the wings of these U''s are cut out with complementary tenons and mortises such that these wings can be fitted together two by two to close the ring, only in a direction perpendicular to their middle planes.
