    • Process for pneumatic classification of mixture of granular particulates by providing an apparatus, entraining mixture, reducing velocity of entraining airstream, and airwashing falling particulates of low aerodynamic support. Specific applications include a method separating mixed granular material based upon dissimilar specific gravities, useful in cleaning firearm ranges by separating lead from backstop material. Falling granular lead particulates can also be airwashed and negative pressure facilitates control of lead dust. Also disclosed are applications that pick up and clean or enrich precious metal bearing ore, and a broad range of applications from heavy mixtures, such as landscape rock, to light mixtures such as grain.
    • 通过提供装置,夹带混合物,减少夹带气流的速度和低空气动力学支持的空气洗涤落下的颗粒来气动分级粒状颗粒的混合物的方法。 具体应用包括基于不同的比重分离混合颗粒材料的方法,其用于通过将反萃材料分离出来来清洁火器范围。 落下的颗粒状铅颗粒也可以是空气清洗的,负压有助于控制铅尘。 还公开了拾取和清洁或富集贵金属轴承矿石的应用,以及从重质混合物(例如风景岩)到轻质混合物如谷物的广泛应用。

    • A concrete lid for an in-ground utilities box includes a reinforcement structure filled with concrete. The reinforcement structure includes a plastic frame and one or more reinforcing trusses that extend between opposing sidewalls of the plastic frame. The reinforcing trusses also extend substantially between the upper and lower edges of the opposing sidewalls. For example, a reinforcing truss may include a flat truss member that is substantially coplanar with the lower edges of the sidewalls, and an arched truss member that extends towards (but does not reach) a plane defined by the upper edges of the sidewalls. The reinforcing trusses include openings that allow wet concrete to pass through. The sidewalls of the plastic frame protect the edges of the lid from damage. The reinforcing trusses reinforce the concrete lid, eliminating the need for separate reinforcement material.
    • 用于地下电力箱的混凝土盖包括一个充满混凝土的钢筋结构。 加强结构包括塑料框架和在塑料框架的相对侧壁之间延伸的一个或多个加强桁架。 加强桁架基本上在相对侧壁的上边缘和下边缘之间延伸。 例如,加强桁架可以包括与侧壁的下边缘基本上共面的平坦桁架构件和朝向(但不到达)由侧壁的上边缘限定的平面延伸的拱形桁架构件。 加强桁架包括允许湿混凝土穿过的开口。 塑料框架的侧壁保护盖子的边缘免受损坏。 加强桁架加固混凝土盖,不需要单独的加固材料。
