    • Site-won spoil from an excavation which is a predominantly non-granular cohesive material can be converted into a material suitable for immediate use as a backfill material by a process of mechanically mixing the spoil with between 0 and 30% by weight or volume of added granular material and between 1 and 10% by weight or volume of a powder material comprising 1–5% lime or with the addition of 1–5% cement and/or 1–5% pulverized fly ash. The process works well with clay soils and the range of suitable spoil can be extended by adding cement to the powder material. The proportions in the mixture are chosen in dependence on the clay and moisture content of the spoil. A machine which can be set to mix the ingredients and water in the correct proportions on site is also described.
    • 从主要是非颗粒状粘结材料的挖掘中获得的现场获得的废弃物可以通过机械混合弃土的方法转化为适合立即用作回填材料的材料,其中添加0至30重量%或体积的添加物 1至10重量%或体积的包含1-5%石灰或加入1-5%水泥和/或1-5%粉碎飞灰的粉末材料。 该工艺适用于粘土,通过向粉末材料中加入水泥可以延伸适当的弃土范围。 混合物中的比例取决于废弃物的粘土和水分含量。 还描述了可以设置在现场混合配料和水以正确比例的机器。

    • An improved braking roller apparatus for preventing unintended movement of cargo containers within cargo compartments of the character found in cargo transport vehicles such as cargo aircraft. The improved braking roller apparatus includes highly novel, internal friction producing elements that smoothly and effectively resist rotation of a pair of cooperating rotors which are driven by a uniquely configured ULD engaging outer housing. The rotors and the cooperating friction elements in turn cooperate with a one way roller clutch assembly in a manner to positively impede rotation of the cargo container engaging outer housing in a first direction which allowing its free, unrestricted rotation in an opposite direction.
    • 一种改进的制动辊装置,用于防止货物集装箱在诸如货机的货物运输车辆中发现的货物的货物舱内的意外移动。 改进的制动辊装置包括高度新颖的内摩擦产生元件,其平滑有效地抵抗由独特构造的ULD接合外壳驱动的一对协作转子的旋转。 转子和配合的摩擦元件依次与单向滚柱离合器组件配合,以便在第一方向上积极阻止货物集装箱接合外部壳体的旋转,这允许其在相反方向上的自由的不受限制的旋转。
