Abstract: An electronic device includes a body having a threaded portion configured to co-operate with a threaded portion of a duct in a sleeve in order to move the device into a final position when the device is turned. The electronic device also includes a hole punch configured to form a through orifice in a pipe while the device is being turned and to enable the device to be inserted into the final position. The electronic device further includes an electronic module configured to be in contact with a fluid passing through the pipe when the device is in the final position. In addition, the electronic device includes at least one electrical connection connected to the electronic module and passing through the body leading to a top face of the body. The body and the at least one electrical connection form a plug of the duct in the sleeve.

Abstract: The invention relates to a tube scraping device including a body having means for scraping the tube, and driving means for driving said body in rotation about the tube. The body is equipped with pivoting jaws. A part of the driving means is borne by a driving structure independent from the body.

Abstract: Method in which the following operations are carried out: a) digging an exploration hole (8) in order to open up a main pipeline (2) which has an upper edge (10) which extends at an upper level (12) which is substantially constant relative to the ground (6), b) using a branch connection (14) which has a support surface (16) and a shaft (18) to which the branch pipe is connected, c) positioning the support surface (16) of the branch connection (14) against the main pipeline (2) so that the shaft (18) is below the upper level (12) of the main pipeline (2), d) fixing the branch connection (14) to the main pipeline (2), e) placing the branch pipe and the main pipeline (2) in communication, f) refilling the exploration hole (8), whilst keeping the branch pipe below the upper level (12) of the main pipeline (2).

Abstract: The following operations are carried out: a) digging an exploration hole (8), b) using a branch connection (10) which includes a main plate (12) and a fixing plate (22) which are held together, c) using a device (1) which has: a support (36) retaining elements, (38) which are connected to the support (36), a foot (40) which is articulated so as to rotate relative to the support (36), actuation elements (44) for displacing the foot (40) between an introduction position and a pressing position, d) placing the foot (40) in an introduction position, e) retaining the main plate (12) on the device (1), f) positioning the support surface (14) of the main plate (12) against the pipeline (2), g) bringing the foot (40) into a pressing position, h) fixing the main plate (12) and the fixing plate (22) together around the pipeline (2).
