    • The present invention is an apparatus and process for cooling and de-steaming hot calcined stucco used in the production of gypsum boards or bagged plaster. The apparatus is a fluid bed stucco cooler and comprises a cooler housing having a plenum having a stucco inlet and stucco outlet. The stucco cooler includes a rotating disk in the plenum. The rotating disk includes nozzle for spraying fluid, and is attached to a rotable shaft extending from the side of the cooler also includes a fluidization pad and agitator to help to mix the air and the stucco powder to insure fluidization, prevent channeling, and prevent the stucco powder from building up on the various components. The air also forces steam from the hot calcined stucco out through an air outlet located at the top of the stucco cooler, thereby de-steaming the stucco. The stucco flows through the plenum and passes over the cooling coils, thereby cooling the stucco as it reaches the stucco outlet.
    • 本发明是用于生产石膏板或袋装石膏中的用于冷却和蒸发热煅烧灰泥的装置和方法。 该设备是流化床灰泥冷却器,并且包括具有灰泥入口和灰泥出口的增压室的冷却器壳体。 灰泥冷却器包括在气室中的旋转盘。 旋转盘包括用于喷射流体的喷嘴,并且附接到从冷却器侧延伸的可旋转轴还包括流化垫和搅拌器,以帮助混合空气和灰泥粉末,以确保流化,防止流动,并防止 灰泥粉从各种组成部分组成。 空气还强制来自热煅烧灰泥的蒸汽通过位于灰泥冷却器顶部的空气出口,从而使灰泥脱蒸。 灰泥流经通风室并通过冷却盘管,从而当灰泥到达灰泥出口时冷却灰泥。

    • A coupling for joining pipe elements in end to end relation is disclosed. The coupling includes interconnectable coupling segments having connection members at opposite ends. The connection members are tightenable for drawing the segments toward one another and into engagement with the pipe elements. Each segment has a concavity positioned between inwardly projecting arcuate surfaces that engage grooves in the pipe elements. The concavities house a sealing member that extends circumferentially around the pipe elements. Angularly oriented surfaces are positioned adjacent to the connection members. The surfaces on facing segments engage one another and cause the segments to rotate in opposite directions about an axis perpendicular to the pipe elements. The concavities are angularly oriented with respect to the axis so that when the segments rotate, the cavities receive the sealing member without distorting it. A method of joining pipe elements end to end is also disclosed.
    • 公开了一种用于以端对端关系连接管元件的联接器。 联接器包括在相对端具有连接构件的可互连联接段。 连接构件是可收紧的,用于将段拉向彼此并与管道元件接合。 每个段具有定位在接合管元件中的槽的向内突出的弧形表面之间的凹陷。 凹部容纳围绕管元件周向延伸的密封构件。 角度方向的表面邻近连接构件定位。 相对的区段上的表面彼此接合并且使得区段围绕垂直于管道元件的轴在相反的方向上旋转。 凹部相对于轴线成角度地定向,使得当片段旋转时,空腔容纳密封构件而不使其变形。 还公开了一种将管元件端对端连接的方法。
