    • A method is provided for cooling prior to decoking a petroleum coke drum having a substantially solidified mass of petroleum coke by initiating the injection of water into the coke drum while the average temperature of the coke within the coke drum is greater than about 500.degree. F., wherein the average flow rate of water injected into the coke drum over the initial 10 minute period of water injection is from about 0.0033 to about 0.01 gpm per cubic foot of coke in the coke drum; and thereafter continuing the injection of water into the drum for a total injection time of at least about 60 minutes, at a flow rate during the 50 minute period immediately following the initial 10 minute period less than about 0.0036 to about 0.011 gpm per cubic foot of coke in the coke drum.
    • 提供了一种方法,用于在通过开始向焦炭鼓内注入水之前对具有基本上固化的石油焦炭的石油焦炭转鼓进行冷却,而焦炭鼓内焦炭的平均温度大于约500°F。 其中在注射初始10分钟时间内注入焦炭转鼓的水的平均流量在焦炭鼓中每立方英尺焦炭为约0.0033至约0.01gpm; 然后在初始10分钟之后的50分钟期间内持续将水注入滚筒中达到至少约60分钟的总喷射时间,小于约0.0036至约0.011gpm /立方英尺 焦炭在焦炭桶中。

    • A modular prosthetic ligament is disclosed for replacing a natural ligament which joins and allows articulation between adjacent ends of two bones. The prosthetic ligament includes a first anchor element, for disposition in the adjacent end of one of the bones, a second anchor element for disposition in the adjacent end of the other bone, and a cable assembly for interconnecting the first and second anchor elements. The cable assembly includes a hollow housing, one side of which is detachably joinable to the first anchor element, and the other side of which includes a slot through which one end of a cable is threaded to extend into the housing hollow. A ball or cylinder is disposed in the hollow of the housing and is coupled to the cable so that when the cable moves in the slot, the ball rolls or moves in the hollow of the housing. The other end of the cable is coupled to the second anchor element.
    • 公开了一种用于替换连接并允许在两个骨的相邻端之间的铰接的天然韧带的组合式假体韧带。 假肢韧带包括第一锚定元件,用于配置在一个骨头的相邻端部,用于配置在另一个骨骼的相邻端部中的第二锚定元件,以及用于互连第一和第二锚定元件的电缆组件。 电缆组件包括中空壳体,其一侧可拆卸地连接到第一锚固元件,并且其另一侧包括狭槽,电缆的一端穿过该狭槽以延伸进入壳体中空部。 球或圆柱体设置在壳体的中空部分中并且联接到电缆,使得当电缆在槽中移动时,球滚动或移动到壳体的中空部中。 电缆的另一端连接到第二锚定元件。
