    • In one aspect, there is disclosed a drawn arc fastener welding process that includes the steps of providing a fastener positioned in a welding tool, providing a weld control, providing a work piece, contacting the fastener against the work piece, energizing a pilot current, lifting the fastener from the work piece and drawing a pilot arc, energizing a main arc for a predetermined duration, short circuiting the fastener relative to the work piece, cyclically redrawing an arc and short circuiting the fastener relative to the work piece at least one additional cycle, dynamically sensing an arc voltage and calculating a derivative signal of the voltage over time for each drawn arc and short circuit of the cycle wherein a position and motion of the fastener relative to the work piece is controlled and the energizing of the arc is controlled, and plunging the fastener into the work piece forming a weld.
    • 一方面,公开了一种拉制弧形紧固件焊接工艺,其包括以下步骤:提供定位在焊接工具中的紧固件,提供焊接控制,提供工件,使紧固件抵靠工件接触,激励引导电流, 将紧固件从工件上提起并拉制一个导向弧,给主弧施加预定的持续时间,使紧固件相对于工件短路,循环地重绘弧并使紧固件相对于工件短路至少一个附加 循环,动态地感测电弧电压并计算每个拉伸弧的电压随时间的导数信号和循环的短路,其中紧固件相对于工件的位置和运动被控制并且电弧的激励被控制 ,并将紧固件插入工件中,形成焊缝。

    • A rotary intake and exhaust system for an internal combustion piston engine that includes an engine having at least one cylinder and piston that define a combustion chamber. A crankshaft is coupled to the piston for moving the piston within the cylinder. A cylinder head is positioned to interface with the combustion chamber and includes a combustion chamber transfer port, and bifurcated intake and exhaust passages, called ports or tracts, formed therein. A driven rotatable shaft is positioned in the cylinder head to interact with the combustion chamber transfer port. The shaft includes intake and exhaust ports wherein rotation of the shaft transfers fluids and gases in and out of the combustion chamber.
    • 一种用于内燃活塞发动机的旋转进气和排气系统,其包括具有限定燃烧室的至少一个气缸和活塞的发动机。 曲轴联接到活塞上,用于使活塞在气缸内移动。 气缸盖定位成与燃烧室接合并且包括燃烧室传送口,并且形成在其中形成的称为端口或管道的分叉进气和排气通道。 驱动旋转轴定位在气缸盖中以与燃烧室传送口相互作用。 轴包括进出口,其中轴的旋转将流体和气体传入和排出燃烧室。
