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.

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.
