    摘要： A non-thermal plasma reactor and method provides individually retained reactor plates. The method comprises stacking an alternating sequence of positive and negative reactor plates to form a reactor stack, placing temporary spacers between the positive and negative reactor plates. In one embodiment, individually retained reactor plates are secured by folds of a ceramic insulating layer extending between plate pairs, with reactor plates secured by the stack retention material and the folds of the ceramic insulting layer. In a second embodiment, individually retained reactor plates are secured with a permanent pleated insulting mica separator disposed on each side of the reactor. In a third embodiment, a retention material extends slightly into the exhaust gas passage at each side of the stack supplying permanent support for the stacked plates.

    摘要： A low profile catalytic converter for use with an internal combustion engine that has a canister provided with a plurality of smooth foil sections arranged in substantially perpendicular relationship with the top and bottom walls of the canister. The smooth foil sections are spaced from each other so as to form a plurality of substantially rectangular passages providing axially extending flow paths for the exhaust gas emanating from the engine. At least one corrugated foil strip is located in each of the passages and an arm is formed with each of the smooth foil sections that is secured together with a portion of the corrugated foil strip by separate welds to the top and bottom walls of the canister.

    摘要： A method of manufacturing an exhaust control valve includes casting first and second subhousings as separate pieces and machining smooth the inner faces of both. Each subhousing has a stem portion and a flow portion. Each flow portion defines a cylindrical bore from which a seat arc extends radially inward and approximately 180° along. The seat arc of the first subhousing lies below, and the seat arc of the second subhousing lies above, a horizontal plane that bisects the subhousings. Each seat arc has a semicircular inner sidewall that serves as a valve seat. Their inner faces facing each other, the two subhousings are mated so that their two stem portions form a stem housing and their two flow portions form a flow housing. During the mating step, the cylindrical bores are aligned to form a flow passage through the flow housing, with the two valve seats spaced equidistantly from a vertical plane defined by the inner faces along which the subhousings mate. In further steps, the method involves boring at least one bore into the stem housing. A rotatable shaft is sealingly enclosed within the bore(s) and it protrudes into the flow passage. Another step entails affixing the valve plate to the shaft so that it will pivot between the opened and closed positions as the shaft is being rotated accordingly.

    摘要翻译： 制造排气控制阀的方法包括将第一和第二子房作为分开的件铸造并使两者的内表面平滑。 每个子座具有茎部和流动部分。 每个流动部分限定圆柱形孔，座弧从该圆柱孔径向向内延伸并且沿着大约180°延伸。 第一座位的座弧位于下方，第二座位的座弧位于上方，将水平平面分为二等分。 每个座弧都有一个半圆形的内侧壁，用作阀座。 它们的内表面彼此面对，两个子座配合，使得其两个杆部分形成杆壳体，并且它们的两个流动部分形成流动壳体。 在配合步骤期间，圆柱形孔对齐以形成通过流动壳体的流动通道，其中两个阀座与由子座配合的内表面限定的垂直平面等距离地间隔开。 在另外的步骤中，该方法包括将至少一个孔钻入杆壳体中。 旋转轴被密封地封闭在孔内并且突出到流动通道中。 另一步骤是将阀板固定到轴上，使得当轴正在相应地旋转时，它将在打开和关闭位置之间枢转。

    摘要： A catalytic converter mat having a high density in areas which coincide with the ends of a substrate to be wrapped thereby and low density between the ends is disclosed which reduces cost of the mat component of a catalytic converter while retaining the benefits of proper mat pressure at the inlet and outlet ends of the substrate to retain and support the substrate without mat erosion and insulation of the substrate from the canister.
