    • An exhaust muffler comprising an outer cylindrical body, front and rear end plates mounted on each end of the outer cylindrical body, porous plates fitted on the insides of the outer cylindrical body and each of the end plates, and partition plates for dividing the internal space of the outer cylindrical body into several chambers, wherein when joining the component parts with each other, three or four component parts are superposed via their joint portions each on the other and integrally joined by laser beam welding so as to obtain a reduction of welding steps and minimize the thermal influence in the manufacturing process while ensuring an air-tight condition of the partitioned chambers. When an exhaust pipe and tail pipe are connected to the end plates, respectively, they are laser beam welded to the end plates in a superposed fashion. Alternatively, the outer cylindrical body is formed in a multiple-layered construction with inner and outer panels which are so formed integral with each other as to squeeze or press inwardly, when assembling, an internally installed unit over its fill periphery, thereby not requiring particular measures for fixedly securing the internally installed unit to the outer cylindrical body. Preferably the outer cylindrical body and end plates are formed on an aluminum-plated or a stainless steel plate, thereby dispensing with a coating after welding.
    • 一种排气消音器,包括外筒体,安装在外圆柱体的每一端上的前端板和后端板,安装在外筒体和每个端板的内侧的多孔板,以及用于分隔内部空间的隔板 的外筒体,其中当将部件彼此接合时,通过它们的接合部分将三个或四个部件彼此重叠并且通过激光束焊接一体地接合,以获得焊接步骤的减少 并且在确保分隔室的气密状态的同时最小化制造过程中的热影响。 当排气管和尾管分别连接到端板时,它们以重叠的方式被激光束焊接到端板上。 或者,外圆柱体形成为多层结构,其中内板和外板彼此一体地形成为一体,以便在组装时挤压或向内挤压内部安装的单元在其填充周边上,从而不需要特别的 用于将内部安装的单元固定地固定到外部圆柱体的措施。 优选地,外圆筒体和端板形成在镀铝或不锈钢板上,从而在焊接之后分配涂层。

    • An edge protector for an electrolysis electrode onto which a thick-electrodeposited copper product is deposited for producing an electrolytic copper product, has an outer surface shape in the central portion thereof which reduces the thickness in that portion to improve uniformity of cooling, and thereby reduce stress cracking as a result of the reduced buildup of thermal stresses. The outer surfaces may be inclined planes or suitable curved shapes that converge from an outer jaw toward an inner jaw. In one embodiment an edge protector is taught such that its top end is angled downward from its center outward at an angle of less than twenty degrees to prevent creation of sharp edges and difficulty in removal. A spreader bar has a shape which enables clamping of the edge protector onto an electrolysis electrode without excessive expansion of the outer jaw, thereby lengthening service life, and easing installation. Both a hollowed and a tapered spreader bar are taught for end insertion.
    • 用于生产电解铜产品的用于沉积厚电沉积铜产品的电解电极的边缘保护器在其中心部分具有外表面形状,其减小了该部分中的厚度,以改善冷却的均匀性,从而减少 由于热应力累积减少,应力开裂。 外表面可以是倾斜平面或适合的弯曲形状,其从外部钳口朝向内部颚部会聚。 在一个实施例中,教导边缘保护器使得其顶端以小于二十度的角度从其中心向外成角度向下倾斜以防止产生尖锐边缘并且难以移除。 扩张杆具有能够将边缘保护器夹持在电解电极上而不会使外侧钳口过度膨胀的形状,从而延长使用寿命,并且使安装变得简单。 一个中空的和一个锥形的吊具杆被教导用于端部插入。
