    • A method for forming a hardened coating on a workpiece, such as a corrugating roll, having an undulated surface. A high velocity oxygen fueled gun is aligned with the undulated surface and a coating material is sprayed onto the surface from the gun to form a hardened coating having substantially uniform surface characteristics. The coating material is a tungsten carbide-cobalt material, or other hard carbide or oxide materials, which is sprayed onto the surface in a direction which is parallel to and offset from a plane passing through the longitudinal center of the roll. During the spraying operation, the gun is traversed along the length of the roll while the roll is rotated.
    • 在诸如瓦楞辊的工件上形成具有波状表面的硬化涂层的方法。 高速氧气喷枪与波纹表面对准,并且涂层材料从喷枪喷射到表面上以形成具有基本均匀表面特性的硬化涂层。 涂层材料是碳化钨 - 钴材料或其它硬质碳化物或氧化物材料,其在与通过辊的纵向中心的平面平行并偏移的方向上喷涂到表面上。 在喷涂操作期间,当辊旋转时,喷枪沿辊的长度移动。

    • A kit or device which can be used by children to create artistic forms from sheets of paper. The kit includes a cutting portion which can be manually operated to cut strips from a sheet of paper and also a portion for creating corrugations and/or curls in paper, such as the cut strips. The cutting portion generally includes a plurality of cutting wheels mounted on separate horizontal parallel shafts for rotation therewith such that the side edges of the cutting wheels on the separate shafts are in cutting proximity with regard to each other. The cutting wheels are contained within an upstanding frame portion secured to a base. The spaced shafts are geared to each other so that manual rotation of one shaft is sufficient to rotate all cutting wheels. The frame portion has a side opening or slot at the cutting level so that a sheet of paper of any width can be accommodated during the cutting operation. A horizontally slidable or adjustable upstanding guide plate is provided to adjust the width of at least one strip of paper cut from the sheet or to eliminate the cutting of at least one strip.
    • 儿童使用的工具包或设备可以从纸张中创建艺术形式。 套件包括切割部分,其可以手动操作以从一张纸切割条带,以及用于在纸中产生波纹和/或卷曲的部分,例如切割条。 切割部分通常包括安装在分开的水平平行轴上的多个切割轮,以便与其一起旋转,使得分离轴上的切割轮的侧边缘彼此相邻地切割。 切割轮被包含在固定到基座的直立框架部分内。 间隔开的轴彼此啮合,使得一个轴的手动旋转足以旋转所有切割轮。 框架部分在切割水平处具有侧开口或槽,使得在切割操作期间可以容纳任何宽度的纸张。 提供水平可滑动或可调节的直立引导板以调节从片材切割的至少一条纸的宽度,或者消除至少一个条带的切割。
