  • Publication number: 20220276116
    Abstract: The present disclosure integrates several methodologies for the detection and location of leaks in pipelines that transport hydrocarbons in liquid or gaseous phase. Detection is achieved through the management and processing of the data obtained by various measuring devices installed at strategic points on the pipeline infrastructure, this system does not alter neither structure nor mechanics of pipe and in case of a leak or flow caused by unauthorized actions, sensor system collect information on the physical variables of the fluid. This system may be made up of acoustic monitoring techniques, detection of negative pressure waves, as well as methods of mass and energy balance, integrated by multiple sensors, which are managed and controlled by electronic systems that process the information to determine the point of occurrence of a leak in digital maps.

  • Publication number: 20190136104
    Abstract: Two-part (2K) polyurethane (PU) adhesives are disclosed based on methylene diphenyl diisocyanate. Also disclosed are methods of manufacture and use. Compared to 2K PUs based on toluene diisocyanate, the disclosed adhesives have lower viscosity and an improved worker safety profile.

  • Patent number: 8420939
    Abstract: Flame retardant, low smoke emission and halogen free energy cable with silane cross-linked polyolefin insulation and polyamide jacket for electrical installations up to 600 V, based on: a) an electric conductor core made of copper or aluminum; b) an insulating layer made of silane cross-linked polyethylene; and c) a flame retardant nylon-6 jacket with low smoke emission; characterized in that said core a) is based on a plurality of soft copper wires with electrical resistivity no greater than 17,241 nOhm.m (0.15328 Ohm.g/m2) equivalent to a IACS 100% conductivity or aluminum with electrical resistivity not greater than 28,264 nOhm.m (0.07639 Ohm.g/m2) equivalent to a IACS 61% conductivity and having reduced insulating thicknesses.

  • Publication number: 20060119573
    Abstract: Systems and methods for controlling a resonant device are described. One described method for braking an actuator includes generating a first actuator signal configured to drive the actuator, the first actuator signal having a first frequency approximately resonant to the actuator, and transmitting the first actuator signal to the actuator. The method also includes generating a second actuator signal, having a second frequency approximately 180 degrees out of phase to the first frequency, the second actuator signal configured to cause a braking force on the actuator, and transmitting the second actuator signal to the actuator.
