    • A penetrant composition for applying to and penetrating into weather exposed surface materials to prevent moss growth thereon is described. The composition is an aqueous solution containing Na.sub.2 O, SiO.sub.2 and a surfactant for increasing the permeability of the composition into the surface material. A method of protecting weather exposed surface material from moss growth thereon is also described. The method involves the steps of providing a composition including water, Na.sub.2 O, SiO.sub.2 and a surfactant. Approximately 1 gallon of the composition is applied per 100 square feet of surface to be protected. The composition is allowed to dry on and in the surface material at ambient temperatures.
    • 描述了一种渗透组合物,用于施加和渗透到暴露于天气的表面材料中以防止苔藓生长在其上。 该组合物是含有Na 2 O,SiO 2和表面活性剂的水溶液,用于增加组合物渗透到表面材料中。 还描述了一种保护暴露于天气的表面材料免受苔藓生长的方法。 该方法包括提供包含水,Na 2 O,SiO 2和表面活性剂的组合物的步骤。 每100平方英尺的待保护表面施用约1加仑的组合物。 使组合物在环境温度下在表面材料上和表面材料上干燥。

    • A cylindrical member maintenance device is comprised of a housing comprised of two hinged halves for being closed around a cylindrical member, such as a stranded steel cable. A rotary helical brush assembly and a rotary longitudinal brush assembly are positioned in the housing and rotatable about an axis of the housing. Each rotary brush assembly is comprised of coaxial split rings with rotary cylindrical wire brushes connected in between and which are independently rotatable about their own axes. Nozzles are positioned on the inside of the housing for applying a cleaning fluid or paint to the cylindrical member. Apertures in the housing are for connecting to a suction device for removing debris, cleaning fluid, and paint to avoid contaminating the environment. Loops on the housing are for attaching to cables for moving the housing along the cylindrical member.
    • 圆柱形部件维护装置包括由两个铰接的半部构成的壳体,用于围绕诸如绞合钢缆的圆柱形构件封闭。 旋转螺旋刷组件和旋转纵向刷组件定位在壳体中并且可围绕壳体的轴线旋转。 每个旋转刷组件包括具有连接在其间并且可围绕其自身的轴独立地旋转的旋转圆柱形丝刷的同轴开口环。 喷嘴位于壳体的内侧,用于将清洁流体或涂料施加到圆柱形构件上。 壳体中的孔口用于连接到抽吸装置,用于清除碎屑,清洁液体和油漆,以避免污染环境。 壳体上的环绕用于连接到沿着圆柱形构件移动壳体的电缆。

    • In one implementation, a computer-implemented method for graphical subselection is provided. The method includes presenting an image to a user. The image includes an original graphic selection set of graphical elements. The method also includes receiving a first user input identifying a first subselection of elements in the original graphic selection set. Additionally, the method includes visually differentiating the first subselection of elements in the image presented to the user. A second user input is received identifying a second subselection of elements in the original graphic selection set. The second subselection of elements is different from the first subselection of elements. Further, the method includes visually differentiating the second subselection of elements in the image presented to the user.
    • 在一个实现中,提供了用于图形子选择的计算机实现的方法。 该方法包括向用户呈现图像。 图像包括图形元素的原始图形选择集。 该方法还包括接收标识原始图形选择集中元素的第一子选择的第一用户输入。 另外,该方法包括在视觉上区分呈现给用户的图像中的元素的第一子选择。 接收识别原始图形选择集中的元素的第二子选择的第二用户输入。 元素的第二子选择与元素的第一子选择不同。 此外,该方法包括视觉区分呈现给用户的图像中的元素的第二子选择。

    • A ladder leveling accessory which may be attached to the legs of a ladder has a configuration which forms an apex remote from leg attachment arms positioned and carries an elongated peg which extends downwardly away from the arms at an angle to the plane in which the arms and thus the legs of the ladder are disposed. The peg may be in the configuration of a spike and, for use in loose or sandy substrates, there may be triangular shaped flanges. A flexible mat is secured above the spike to the apex and conforms to the configuration of the ground to provide further stabilization to the system.
    • 可以附接到梯子的腿部的梯子调平附件具有形成远离腿部附接臂的顶点的构造,该腿部附接臂定位并且承载细长栓钉,该细长栓钉以与手臂的平面成角度的方式从臂向下延伸远离臂 从而设置梯子的腿部。 钉可以是尖钉的构造,并且为了在松散或砂质的基底中使用,可以具有三角形的凸缘。 将柔性垫固定在尖端上方至顶点,并符合地面的结构,以便为系统提供进一步的稳定。
