摘要： A protective shield for machines having an operator station protects an operator located on the operator station during operation of the machine. The protective shield defines a flexible curtain of elongated members which covers an exposed side of the operator station, but yet is also of a construction that allows the operator to reach and see through the curtain when desired. The protective shield has an adjustable height to accommodate a variety of machines and to adjust to underground mines having different sizes and shapes. The protective shield is easily removable from and reattachable to machines without the use of additional tools, thereby enhancing its versatility and usefulness. In a preferred embodiment, the protective shield comprises a somewhat stretchable chain mesh, which hangs from a roof canopy extending along side the operator station.

摘要： A mining machine that has a chassis that defines an operator area thereon and has a mining assembly attached thereto. A vertically extending shield assembly is supported on the chassis to prevent material that is dislodged during the mining process from inadvertently entering the operator area. The shield assembly may be selectively vertically extendable and may be equipped with a ventilation duct assembly to withdraw dust and gases away from the operator area. The mining machine may be equipped with a mining assembly that extends the entire width of the chassis and that can be advanced forwardly of the chassis and swung down across the seam face during mining. The present invention may also be equipped with a quick disconnect assembly for detachably mounting the mining assembly or other mining implement to the mining machine.
摘要翻译：一种采矿机，其具有在其上限定操作者区域并具有附接到其上的采矿组件的底盘。垂直延伸的屏蔽组件支撑在底盘上，以防止在采矿过程中被移除的材料不经意地进入操作者区域。屏蔽组件可以选择性地垂直延伸，并且可以配备有通风管道组件，以将灰尘和气体从操作者区域排出。采矿机可以配备有采矿组件，其延伸底盘的整个宽度，并且可以在底盘向前推进并且在采矿期间向下摆动穿过接缝面。本发明还可以配备有用于将采矿组件或其他采矿工具可拆卸地安装到采矿机的快速断开组件。

摘要： A yieldable confined core mine roof support including a container and a filler placed within the container. The container is yieldable and the filler is compressible. The combination of a filler within a container produces a mine roof support which is yieldable under a substantially axial load and which increases in load carrying ability as it yields, impeding any decrease in the distance between a mine roof and a mine floor, minimizing or preventing mine roof collapse and mine floor heave, buckling or punching.
摘要翻译：可收缩的有限核心矿顶屋顶支架，包括置于容器内的容器和填料。容器是可屈服的并且填料是可压缩的。容器内的填料的组合产生了一个在大体上轴向载荷下可屈服的矿顶支撑件，并且在承载能力增加的同时增加了承载能力，阻碍了矿顶和矿井之间距离的任何减小，从而最小化或防止了我的屋顶倒塌和我的地板起伏，弯曲或打孔。

摘要： After compressive shrinking, moist (15% to 25% moisture by weight of fabric), preshrunk fabric is directed into a drum-type drier in which it is restrained while being dried to a moisture content of say 5% to 14%. Thereafter, the fabric is completely dried in a loop-type drier and additionally preshrunk while the fabric is in a relaxed state.
