    • An electronic quick change cartridge (10) for a welding helmet. The cartridge base (26) is formed of an optically dense polycarbonate or like material that acts as a passive filter to provide eye protection during the welding process. A port (30) in the base receives a variable density LCD cell (35) and a cavity (27) formed in the base (26) receives the electronics for driving the cell. Optical masks (11, 50) prevent light leakage through any interfaces of the structure. When low light levels are present, the welder views a work piece through an essentially transparent or slightly opaque LCD cell. When an arc is struck, the LCD cell (35) darkens to a shade corresponding to the shade of the surrounding polycarbonate material. The welder then can view the work piece through the LCD cell and all the optically unobstructed portions of the polycarbonate base (26) surrounding the LCD cell (35) thereby to have an expanded viewing area during the actual welding operation.
    • 一种用于焊接头盔的电子快速更换盒(10)。 盒基座(26)由光密度聚碳酸酯或类似材料形成,其作为无源滤光器,以在焊接过程中提供眼睛保护。 基座中的端口(30)接收可变密度LCD单元(35),并且形成在基座(26)中的空腔(27)接收用于驱动单元的电子元件。 光学掩模(11,50)通过结构的任何接口防止光泄漏。 当存在低光级时,焊工通过基本上透明或稍微不透明的LCD电池观察工件。 当电弧被击打时,LCD单元(35)变暗到对应于周围聚碳酸酯材料的阴影的阴影。 焊机然后可以通过LCD单元观察工件,并且围绕LCD单元(35)的聚碳酸酯基座(26)的所有光学无阻碍部分,从而在实际焊接操作期间具有扩大的观察面积。

    • It includes a frame (50) and further includes a tray (53) to hold paint containers, such as a paint pan (61), as well as tools, accessories and the painter's personal items. The tray (53) may be segmented or divided into compartments for the paint pan (61) and various articles. Legs (54) are pivotally mounted on the frame (50) for ease of storage and transport, and the legs (54) have stored and depending positions, respectively. A removable cover (56) is provided for the tray (53); and the cover (56) may be disposed between the legs (54) to further support the legs (54) and to serve as as shelf during use of the mobile work station (10).
    • 它包括框架(50),并且还包括用于容纳诸如油漆盘(61)的油漆容器的托盘(53),以及工具,附件和画家的个人物品。 托盘(53)可以被分段或分成用于油漆盘(61)和各种物品的隔间。 腿部(54)枢转地安装在框架(50)上以便于存储和运输,并且腿部(54)分别具有存储和依赖的位置。 为托盘(53)提供可移除的盖(56); 并且所述盖(56)可以设置在所述腿部(54)之间,以进一步支撑腿部(54)并且在使用移动工作站(10)期间用作搁板。
