    • Devices and methods for removing snow are disclosed. A snow removal device in accordance with the present invention includes an elongate handle having a distal end and a proximal end, and a flexible sheet having a leading edge and a leading portion proximate the leading edge. The leading portion of the flexible sheet is fixed to the elongate handle proximate the distal end thereof. The flexible sheet has a first position defining a gliding surface, and a second position wherein the flexible sheet is substantially flat. The flexible sheet is, preferably, biased to assume the first position.

    • A method for installing a hanger in gypsum board wherein the hanger comprises a steel strip bent into a Vee to provide two legs, the first leg being arcuate with a pointed end and functioning as an anchor when installed in the board, and the second leg being straight and having a u-bend formed at its terminus to function as a hook, the method comprising: providing a tool comprising a first leaf and a second leaf formed from flexible strips, the leaves being secured to each other at their distal ends so that the faces of the leaves are urged against each other along their lengths, with the first leaf having a slot formed therein adjacent its proximal end sized to receive therethrough the u-bend at the terminus of the second leg of the hanger; inserting the u-bend of the hanger through the slot so that the u-bend is captured between the leaves; placing the tool against the wall of the board with the outer face of the second leaf in contact with the wall and with the pointed end of the first leg of the hanger in contact with the wall; and progressively driving the pointed end of the first leg of the hanger into the board until the hanger is seated.
    • 一种用于在石膏板中安装衣架的方法,其中所述衣架包括弯曲成V形的钢带以提供两个腿,所述第一腿具有尖端弓形并且当安装在所述板中时用作锚固件,并且所述第二腿部 在其末端具有形成在其端部的u形弯曲以起到钩的作用,所述方法包括:提供包括由柔性条形成的第一叶片和第二叶片的工具,所述叶片在其远端彼此固定,使得 叶片的表面沿着它们的长度彼此抵靠,其中第一叶片具有形成在其中的狭槽,邻近其近端的尺寸设置成在衣架的第二腿的终点处穿过其中的U形弯曲部; 通过插槽插入衣架的U形弯头,使得U形弯曲部分被收纳在叶片之间; 将所述工具放置在所述板的壁上,使所述第二叶片的外表面与所述壁接触并且所述衣架的所述第一腿的尖端与所述壁接触; 并逐渐地将衣架的第一腿的尖端推入板中,直到衣架就座。

    • An apparatus for generating a beam of light with a perceived beam having constant brightness comprising a flashlight apparatus having a parabolically shaped reflector, and the flashlight apparatus also having a equal-sided rotating hexagon present along the axis of the reflector. The outside surfaces of the hexagon are covered with a mirror-like surface for deflecting the light rays emanating from a light source located at the focus of a reflector in a changing pattern as the hexagon rotates about its axis, which is perpendicular to the reflector axis. The changing light pattern eliminates a dark area of the beam from the flashlight as the changing pattern directs light rays across the dark area as the hexagon rotates.
    • 一种用于产生具有恒定亮度的感知光束的光束的装置,其包括具有抛物线形反射器的手电筒装置,并且手电筒装置还具有沿着反射器的轴线存在的相等的旋转六边形。 六角形的外表面被镜状表面覆盖,用于当六边形围绕其垂直于反射器轴线的轴线旋转时,偏转位于反射器焦点处的变化图案中的光源发出的光线 。 当六边形旋转时,变化的图案消除了来自手电筒的光束的暗区域,因为改变的图案将光线引导到黑暗区域。

    • A method of coating a pre-formed trainable material, such as nitinol wire, with a heat resistant substance, heat treating, and cooling to form a desired shape. The substance can be removed by various methods after heat treatment, depending upon the composition of the substance. The method includes forming a trainable material around a mold that dissolves, vaporizes, or can otherwise be removed. The method is useful for forming complicated shapes that would be expensive or impossible to form by conventional methods.
    • 用耐热物质涂覆预先形成的可训练材料如镍钛诺丝的方法,热处理和冷却以形成所需的形状。 根据物质的组成,可以通过热处理后的各种方法除去物质。 该方法包括在模具周围形成可溶解,蒸发或以其它方式除去的可训练材料。 该方法对于形成复杂的形状是有用的,其通过常规方法成本昂贵或不可能形成。
