Abstract: The invention relates to an anchoring kit for a drilling machine provided with a frame, the anchoring kit including at least a first anchoring module having: a first part including an anchoring device for immobilizing the first part in the soil; a second part including a device for fixing to the frame; and a displacement device for moving the second part relative to the first part along a first direction.

Abstract: The invention provides a boring machine (10) for making a trench (T) in soil (S), the machine comprising a frame (12) that extends along a longitudinal direction (A), said frame (12) carrying a boring device (20) provided with four rotary boring members driven by four motors about axes of rotation that are stationary relative to one another.

Abstract: A connection clip electrically connects one of the contact terminal strips of a circuit breaker to a terminal strip for connection to a busbar. At least one opposed pair of independent contact fingers in the form of a bridge is made of conducting material and each opposed pair of contact fingers has two end contacts. The two independent contact fingers press via their end contacts respectively on the two opposite faces of either a terminal strip or busbar, and are urged elastically towards one another by the action of springs compression fitted between a connection frame and a bearing surface of the independent pairs of contact fingers. The independent pairs of contact fingers are covered by a coating containing carbon which provides lubrication to facilitate draw-in of the clip, while reducing the risks of welding at the level of the contact points.
