  • Patent number: 8507832
    Abstract: A method of repairing in situ a pipe or tank of thermo-fusible material, with a step for installing an electric heating element, the heating element including electrical conductors, and with a step for supplying said conductors with appropriate electric energy. The electrical conductors are supplied by a control panel set up prior to the repair and matching, for different thermo-fusible materials and different types of damage of the pipe or tank to be repaired, at least one technical characteristic of the pipe or tank, one characteristic of the electric energy to be applied and a profile of the application time of the electric energy.
    Type: Grant
    Filed: August 16, 2005
    Date of Patent: August 13, 2013
    Assignee: Gaz de France

  • Patent number: 8049146
    Abstract: The invention relates to a device and a method for welding two polymer parts via fusion using a heater mat knitted from a resistive wire coated with an insulating varnish, the heater mat being given a final shape. The heater mat is resistive wire having a diameter ranging from 0.2 mm to 0.3 mm, and has approximately parallelepiped meshes, the dimensions of which range from 1.5×3 mm2 to 2.5×4.5 mm2.

  • Patent number: 7325559
    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).

  • Patent number: 7200456
    Abstract: The invention concerns an identification process that makes it possible to confer traceability to manufactured products (PROD), from data of origin (C, D) initially brought together at a source point (P_SOURCE) and including a control identification number (C) and manufacturing data (D) common to these products (PROD). The process of the invention provides for the formation of two parallel information flows, (?1 and ?2), each of which ensures a propagation of the data of origin (C, D) in time and space from the source point (P_SOURCE), and includes three tests (COMPAR—1, COMPAR—2, COMPAR—3) that makes it possible to verify the internal consistency and integrity of these data of origin in the form in which they are propagated.
