    • A forwardly opening cylindrical housing is mounted on the forward end of a wheeled frame coupled to the front of self-propelled prime mover and the rear of the housing includes a forwardly facing axial inlet and radial discharge rotor assembly mounted therein. The housing includes a tangential outlet for the rear end thereof aligned with the rotor assembly and the outlet has the inlet end of conduit means connected thereto for conveying large volumes of air having forage entrained therein to a remote bin into which the discharge end of the conduit opens. The forward end of the housing includes generally diametric stationary bar structure and a forward extension of the rotor shaft includes radial cutting blades spaced slightly axially from the stationary bar.
    • 向前开口的圆柱形壳体安装在联接到自推进原动机前部的轮式框架的前端上,并且壳体的后部包括安装在其中的向前面向的轴向入口和径向排出转子组件。 壳体包括用于其后端与转子组件对准的切向出口,并且出口具有连接到其上的导管装置的入口端,用于将其中夹带有草料的大量空气输送到远程仓,导管的排出端 打开 壳体的前端包括大致直径的固定杆结构,并且转子轴的向前延伸部包括与固定杆稍微轴向间隔开的径向切割刀片。

    • A tinted color value is produced for a surface of an object in a computer generated scene. The surface is illuminated by a light source having a lighting color value associated with the light source. A first reflected color value is calculated for the surface. The first reflected color value is calculated based on an assumption that the surface is illuminated by white light rather than the lighting color value associated with the light source. A desaturated color value is computed using the first reflected color value. A tinted color value is computed by combining the desaturated color value with the lighting color value associated with the light source. The tinted color value is stored.
    • 为计算机生成的场景中的对象的表面产生着色的颜色值。 表面由具有与光源相关联的发光颜色值的光源照射。 为表面计算第一个反射色值。 基于由白光照亮表面而不是与光源相关联的照明颜色值的假设来计算第一反射色值。 使用第一反射颜色值计算去饱和色值。 通过将去饱和颜色值与与光源相关联的照明颜色值组合来计算有色颜色值。 有色颜色值被存储。
