    • A wear-resistant surface structure having a high resistance to impact and thermal shock, suitable for a wide variety of tools and implements, is prepared by bonding carbide particles together with a substantially pure copper matrix in the absence of oxygen. The carbide-copper surface structure can be bonded to the working surface of a ferrous tool simultaneously with the aforementioned bonding process, or at a later time. Although attachment of the surface structure to a ferrous tool normally requires heating of the tool to a softening temperature, such softening may be corrected by subsequently quenching the combined ferrous tool and carbide-copper surface structure from an austenitizing temperature without cracking the copper matrix. Refractory sheet materials are used to contain the carbide and matrix material during liquefaction of the matrix material during the formation of the surface structure.
    • 通过在不存在氧的情况下将碳化物颗粒与基本上纯的铜基质结合在一起,制备适用于各种工具和工具的耐冲击和热冲击的耐磨表面结构。 碳化物 - 铜表面结构可以在上述接合工艺的同时或随后的时间结合到铁工具的工作表面上。 尽管将表面结构附着到铁质工具上通常需要将工具加热至软化温度,但是可以通过随后从奥氏体化温度淬灭组合的亚铁工具和碳化物 - 铜表面结构而不破坏铜基体来校正这种软化。 在形成表面结构期间,在基体材料的液化期间,使用难熔片材来容纳碳化物和基体材料。

    • A shear for cutting sheet material which functions by pivoting a specially constructed pointed blade about an axis by means of an arm so that the blade pierces into and then cuts the sheet is described as well as the method for its use. The blade is constructed such that it has double cutting edges forming a point wherein the cutting edge towards the pivot axis for the arm is concave and forms the point with the other cutting edge in a shape which approximates a shark's tooth. The blade pierces the sheet when the arm is pivoted towards the sheet and then cuts outward along a square edged surface on a frame supporting the arm away from the place where the sheet was pierced by the point. The shear is particularly adapted for the hand cutting of U shaped building channel to a predetermined length.
    • 用于切割片材的剪切装置,其功能是通过使用特殊构造的尖锐的刀片围绕轴线枢转,从而使得刀片刺入并切割片材,并描述其使用方法。 刀片被构造成使得其具有形成点的双切削刃,其中朝向臂的枢转轴线的切削刃是凹入的,并且与另一个切削刃形成接近鲨鱼齿的形状的点。 当手臂朝向纸张枢转时,刀片刺穿纸张,然后沿支撑手臂的框架上的正方形边缘表面向外切割,远离纸张被刺穿的位置。 剪切特别适用于将U形建筑物通道手工切割成预定长度。
