Abstract: A strainer assembly for straining a liquid, such as paint, to be poured into a container includes a tubular strainer support having a continuous imperforate side wall structure with an open top, an open bottom, and an annular exterior flange for removably resting on the open top of the container for holding the strainer support in an upright position above the container. A filter medium, such as a mesh filtering cloth, is secured to the top of the support for holding it in the interior of the support above the container. Paint is poured through the filtering cloth to filter the paint before it passes into the container. In one embodiment, the strainer support includes an annular ridge recessed in the exterior side wall of the support adjacent the open top of the support to provide a second means for mounting the strainer support in an inverted position over a smaller-sized container. A further embodiment comprises a molded plastic support with integrally molded clips that can be broken off and used to hold the filter cloth in place. In a further embodiment, the strainer support is of stackable configuration in which an annular shoulder projecting into the upper interior portion of the support is adapted to engage the top lip of an identical tubular support when the two supports are stacked to provide an interference fit that avoids the tubular supports sticking together when positioned in a tall stack.

Abstract translation: 用于使诸如油漆的液体变形的过滤器组件被倒入容器中包括具有连续无孔壁侧结构的管状过滤器支撑件，其具有敞开的顶部，敞开的底部和用于可拆卸地搁置在开口上的环形外部凸缘 用于将过滤器支撑件保持在容器上方的直立位置的容器的顶部。 诸如网状过滤布的过滤介质固定到支撑件的顶部，以将其保持在容器上方的支撑件的内部。 油漆通过过滤布倒入，以便在油漆进入容器之前对其进行过滤。 在一个实施例中，过滤器支撑件包括凹入到支撑件的外侧壁中的环形凸起，其邻近支撑件的开口顶部，以提供用于将过滤器支撑件以倒置的位置安装在较小尺寸的容器上的第二装置。 另一实施例包括具有整体模制的夹子的模制塑料支架，其可以被分解并用于将滤布保持在适当的位置。 在进一步的实施例中，过滤器支撑件是可堆叠构造的，其中当两个支撑件堆叠时，突出到支撑件的上部内部的环形肩部适于与相同的管状支撑件的顶部唇缘接合以提供过盈配合， 避免在定位在高堆叠中时将管状支撑件粘在一起。

Abstract: A variable electric resistor device comprises a block of electrical insulating material. An elongated member of current resistive metal is removably positioned in the insulating material. A pair of electrically conductive terminal leads are each electrically connected to a corresponding end of the current resistive member. An elongated ancillary member of electrically conductive material is embedded in the insulating material in spaced parallel relation with the current resistive member. A plurality of spaced transverse internally threaded bores are formed through the ancillary member. A plurality of spaced bores are formed through the block extending from both sides of the internally threaded bores from the current resistive member to a surface of the block. A plurality of electrically conductive screws are each threadedly coupled to a corresponding one of the threaded bores and extend in the corresponding bore thereof in a manner whereby selected screws are movable into electrical contact with the current resistive member.
