    Abstract: An assembly for induction heating an exhaust gas flow includes a substrate and linear cells for the flow of the gas through the substrate from a front end of the substrate body to a back end. Metal members such as pins or wires have linear supporting parts projecting from a front end of the substrate into front-end parts of the cells. The metal members have turbulence-inducing part to generate turbulence in the exhaust gas flowing into the cells and through the substrate. The turbulence-inducing parts are integral with respective linear supporting parts and extend away from the substrate. Configurations of an induction heating coil and a magnetic flux concentrator are adapted for the particular location and form of the pins.

    Abstract: A gaseous emissions treatment component has a honeycomb substrate along and through which extend elongate cells for the passage of gaseous emissions through the substrate. The cells are bounded by walls dividing adjacent cells from one another. Metal elements occupy and extend along some of the cells. A metal element has an outer surface shape matching the inner surface of an immediately adjacent part of the cell within which the metal element is located.

    Abstract: As wire is wound around and onto the surface of a former to form a coil, perturbations such as waves are introduced into turns of the coil, each perturbation being formed in a length of the wire less than the full length of a respective turn and projecting along the former surface, the perturbation having an initial shape and size. The coil is taken from the former and fixed in form. A surrounding jacket is radially collapsed onto the wire coil to uniformly press the coil against an internal compressible body in the course of which the overall diameter of the coil is reduced. Resulting stresses in the wire generated during the collapse are relieved by alteration of the perturbations from their initial shape and size to a subsequent shape and size.

    Abstract: A method is disclosed for loading elongate wire lengths into elongate cells of a honeycomb ceramic substrate unit for a gaseous emissions treatment assembly, the cells each having a small cross-sectional area, the area shape matching the cross-sectional shape of the loaded wire lengths and marginally greater in area size than the wire lengths. A wire length is formed with a generally pointed end tip by pulling adjacent parts of a wire along the wire axis respectively in opposite directions from a desired wire breakage site. The tension and timing of the pulling operation are selected so that a desired tip profile is achieved. Initial alignment is done using machine vision. Subsequent adjustment is effected in dependence on feedback from sensors mounted close to the end of a wire insertion arm. Breakage and push insertion of wires is done using alternating gripping and moving of chucks or collets which have aperture shapes close in profile to the outer profile of the wire lengths.

    Abstract: An assembly for treating gaseous emissions has a substrate along which extend cells for the passage of emissions gas. Lengths of conducting wire are located in a set of the cells and an induction heating coil is used to generate a varying electromagnetic field, so as to inductively heat the lengths of conducting wire. The substrate body has a front for entry of flowing emissions gas to be treated into the substrate body and a back for exit of treated gaseous emissions gas. The lengths of conducting wire have projections extending from the front and/or back of the substrate body so that when inductively heated, the wire parts in the substrate body heat the surrounding substrate and the wire projections heat the flowing emissions gas directly.
