  • Patent number: 8819615
    Abstract: A first assembly of critical cells is to be monitored. An equivalent capacitance of output cells coupled to the critical path is determined. Logic level inputs of the critical cells for signal propagation are also determined. A second assembly of control logic cells is provided which copies the first assembly in terms of number of cells, type of cells and cell connection such that each of the control cells is a homolog of a corresponding critical cell. Charge cells are provided at the outputs of the control cells having an equivalent capacitance in accordance with the determined capacitance of the output cells. For each control cell, logic levels are asserted in accordance with the determined configuration of the critical path. A signal generator applies a signal the input of the second assembly and a signal receiver is coupled to the output of the second assembly.

  • Publication number: 20070026157
    Abstract: The method for covering an object to be coated (40) with a meltable covering comprises the following steps: establishment of a flame (44), the direction of the flame (F) thereof being oriented towards the object to be coated and introduction of an amount of meltable covering material into the flame. The temperature of the flame is sufficiently high in order to result in the at least partial melting of the meltable material. The speed of the flame is chosen in such a way that the meltable covering material thus melted is projected onto the object to be coated. At least one part of the amount of meltable coating material is in a melted stated when it impacts upon the object to be coated. The amount of meltable covering material includes powder. The invention can be used for coating cast iron pipes.

  • Patent number: 6656318
    Abstract: The invention concerns a method of joining two reinforced thermoplastic material tubes having the same diameter. Ends of the two tubes are first butt welded along a peripheral weld. After forming the weld, a reinforced thermoplastic material outer jacket is fitted over most of the length of the peripheral weld, extending on either side of the weld over end sections of the two tubes. The outer jacket is heated and pressed radially until the outer jacket and the end sections of the two tubes interpenetrate.
