    • A liquid filter apparatus particularly useful in removing particulates from parts washing solvent. A filter assembly includes an exterior, fluid-impermeable container, preferably in the form of a flexible sidewall bag, and an interior filter element with permeable sidewalls and inlet and outlet ends, preferably in the form of a sleeve. In use, liquid entering the sleeve may pass unfiltered entirely through the sleeve and exit through a sidewall of the exterior container, or all or any part of such liquid may pass through the filter sleeve and into a portion of the apparatus outside the sleeve but inside the exterior container. From this portion, the liquid emerges in a filtered condition. Consequently, the filter continually operates in both filtration and bypass modes. Preferably the flexible sidewall container is received within a rigid support housing, two filter units are provided, and their inlets and outlets are removably secured to a manifold controlling passage of fluid to be cleaned from a liquid pump assembly and to another part of a parts washer associated with the filter.
    • 一种液体过滤装置,特别用于从洗涤溶剂的部件中除去微粒。 过滤器组件包括优选为柔性侧壁袋形式的外部流体不可渗透容器,以及具有可渗透侧壁和入口端和出口端的内部过滤器元件,优选地为套筒形式。 在使用中,进入套筒的液体可能未经过过滤,通过套管穿过外部容器的侧壁,或者这些液体的全部或任何部分可能通过过滤器套筒并进入套筒外部的一部分,但内部 外部容器。 从该部分,液体以过滤状态出现。 因此,过滤器连续运行在过滤和旁路模式。 优选地,柔性侧壁容器被容纳在刚性支撑壳体内,设置两个过滤器单元,并且它们的入口和出口可移除地固定到液体泵组件的待清洁流体的歧管控制通道和部件垫圈的另一部分 与过滤器相关联。

    • A safety cover assembly for use with an associated storage drum. The assembly includes a drum insert with a collar having a two-part cover assembly disposed atop the collar. The moveable part of the cover assembly is actuated by one portion of a crank mechanism, the other portion of which includes a pair of ends secured to a treadle and riser assembly. In use, pushing down on the treadle lowers the one portion of the crank mechanism, and raising the other portion and the associated cover. The treadle and riser assembly is open at the rear to facilitate removal and replacement of the drum. The moveable cover part may be secured to the crank by a fusible link for fire protection.
    • 一种与相关存储鼓一起使用的安全盖组件。 组件包括具有套环的鼓式插入件,其具有设置在套环顶部的两部分盖组件。 盖组件的可移动部分由曲柄机构的一部分致动,曲柄机构的另一部分包括固定到踏板和立管组件的一对端部。 在使用中,向下推动踏板降低曲柄机构的一部分,并提升另一部分和相关联的盖。 踏板和提升板组件在后部是开放的,以便拆卸和更换滚筒。 可移动盖部件可以通过用于防火的可熔接头固定到曲柄上。

    • A spray-entrapped product such as dispensed by an MDI device includes an elongated passageway having a mouthpiece portion and a main chamber portion. The MDI device is mounted to direct a medication spray into the main chamber. A first air inlet allows a low-level inspiratory breath to be developed through the unit prior to operation of the MDI device. When the MDI device is operated a second, air inlet is opened, allowing a higher-level breath to be developed, which causes a high level of mixing with the MDI spray for efficient draws into the lungs. The second air inlet remains open after MDI operation ceases, insuring that a complete, high flow rate breath can be made to fully sweep the medication out of the chamber.
    • 通过MDI装置分配的喷雾捕获的产品包括具有接口部分和主室部分的细长通道。 MDI装置被安装成将药物喷雾引导到主室中。 在MDI装置的操作之前,第一进气口允许通过该单元开发低水平的吸气呼吸。 当MDI装置操作第二个时,空气入口打开,允许高级呼吸发展,这导致与MDI喷雾的高水平混合以有效地吸入肺部。 MDI操作停止后,第二个进气口保持打开状态,确保可以进行完整的高流速呼吸,以将药物全部从腔室中扫出。
