    • A retrofittable filterless drain separator has an outer housing with a spherical section and an inner holding area including an inner spherical segment which is positioned and spaced apart from the spherical section of the outer housing. The separator includes vane in an inlet portion thereof which serves to direct passing liquids against an inner spherical centripetal separator so that the flow path of all liquids together with any entrained solids in the flow path is directed along a curved path which forces separation of particulate material from the liquid. A passage in the centripetal separator section allows liquid to pass through and out of the drain while retaining the solid or particulate matter in the centripetal separator. A component allowing access disposed in the spherical section of the outer housing permits easy access to the internal surface of the centripetal separator to facilitate the removal of any entrapped solid or particulate matter. The difference in the diameters between the outer spherical section and the inner centripetal section provides an emergency flow path for any liquid should the outlet aperture of the centripetal separator become clogged.
    • 可变形的无滤芯排水分离器具有外壳体,其具有球形部分和内部保持区域,该内部保持区域包括与外壳体的球形部分定位和间隔开的内部球形部分。 分离器包括在其入口部分中的叶片,其用于将通过的液体引导到内部球形向心分离器上,使得所有液体的流动路径与流动路径中的任何夹带的固体一起被引导沿着弯曲的路径,其强制颗粒材料的分离 从液体。 向心分离器部分中的通道允许液体通过并排出排水管,同时将固体或颗粒物质保持在向心分离器中。 允许通过设置在外壳的球形部分中的部件允许容易地进入向心分离器的内表面,以便于去除任何夹带的固体或颗粒物质。 如果向心分离器的出口孔堵塞,则外球面部分和内向心部分之间的直径差异为任何液体提供了紧急流路。

    • A toy train box car includes an electrically operated miniature motor and gear drive which initially actuates a shuttle mechanism to open a sliding door and cause cargo items to be moved from a storage bin for loading onto a hand cart. As the door opens, a cold mist generator is energized to simulate cargo being unloaded from a refrigerated box car. The shuttle mechanism includes a rack and pinion which moves a figure pushing the hand cart out of the fully open door and an ejector arm offloads the cargo items onto an external loading ramp. The operating cycle then returns the hand cart into the car to receive another cargo item when the door is fully closed. The cycle is then completed and the motor inactivated until a new cycle is initiated.
    • 玩具火车箱车包括电动微型电动机和齿轮传动装置,其最初致动穿梭机构以打开滑动门,并使货物从用于装载到手推车上的存放箱移动。 当门打开时,冷雾发生器通电,以模拟从冷藏车厢卸载的货物。 梭子机构包括齿条和小齿轮,齿条和小齿轮使将手推车从完全打开的门推出的图形移动,并且弹射臂将货物卸载到外部装载斜坡上。 当门完全关闭时,操作周期然后将手推车放回车中以接收另一货物。 然后,循环完成,马达停用,直到开始新的循环。
