    Abstract: A tensioning system for a tracked vehicle. The present invention provides for adjusting tension of a track by moving the sprocket relative to the rollers in a substantially vertical direction. The system comprises a sprocket assembly, a roller assembly, a track, and a tension adjustment assembly. The tension adjustment assembly includes a tension bolt threaded through a tension nut that is secured to the sprocket assembly. The bolt threads through the nut and contacts the roller assembly. As the bolt is threaded or unthreaded, the sprocket assembly is moved relative to the roller assembly in a substantially vertical direction. As the assemblies move relative to each other, tension in the track is resultantly adjusted.

    Abstract translation: 跟踪车辆的张紧系统。 本发明通过在大致垂直的方向上相对于滚子移动链轮来提供轨道的张力。 该系统包括链轮组件，辊组件，轨道和张力调节组件。 张力调节组件包括螺纹穿过紧固螺母的张紧螺栓，该张紧螺母固定到链轮组件。 螺栓穿过螺母并与滚子组件接触。 当螺栓是螺纹或无螺纹时，链轮组件相对于辊组件在基本垂直的方向上移动。 当组件相对于彼此移动时，轨道中的张力被调整。

    Abstract: A plant for continuous production of cellulose triacetate in a heterogeneous phase, comprising consecutively arranged apparatus for activating, acetylation and benzene washings, benzene stripping, partial saponification, water washings and final product drying. The apparatus for activating, the apparatus for acetylation and benzene washings, the apparatus for benzene stripping and the partial saponification apparatus are interconnected by connecting adaptors for conveying the fibrous reaction mass from one apparatus to another and provided with means for creating therein a sealing plug from the conveyed reaction mass. Said means for the creation of the sealing plug is in the form of a screw conveyer with a valve arranged at its discharge orifice and spring-loaded in the direction opposite to the direction of the fibrous reaction mass conveying.
