Abstract: A form system is provided for forming a structural column assembly of the type used for erecting building structures and the like, such as a concrete column or footing formed in situ in an earthen hole. The system includes a support system, including a wire support member and an associated base foam ring having an offset center hole corresponding to the centerline of the concrete footing, which is placed at the bottom of the earthen hole. A lower vertical form system, including multiple interlocking pieces, is assembled and joined at one end to an offset disk member. The disk member of the lower vertical form system is then placed onto the base foam ring in abutting engagement. The form system is then plumbed and positioned, e.g., in relation to one or more layout strings. Once the form system is in the correct position, the earthen hole is backfilled, e.g., with dirt or other material, thus holding the properly positioned form system in place. The lower vertical form system is then cut to grade.

Abstract: A tool system is provided for aligning and plumbing a poured concrete form (e.g., a lower vertical form portion) for forming a structural column assembly of the type used for erecting building structures and the like, such as a concrete column or footing formed in situ in an earthen hole. The system includes a center line running vertical to the length of the tool and a two-way level system incorporated therein. The tool can be used to line up the lower vertical form portion with a layout string and plumb the lower vertical form portion square. A metering pole that can be locked in place is used to lower and raise the tool into and out of the lower vertical form portion, wherein the tool is completely rotatable about the metering pole. Once the lower vertical form portion is aligned with the tool, the earthen hole is back filled, thus holding the lower vertical form portion in place in the correct position.

Abstract: To provide linearity correction to horizontal scanning current, a linearity coil is coupled to the horizontal deflection winding of a horizontal deflection circuit. The magnetic structure of the linearity coil includes a magnetizable material with generally rectangularly cross-sectioned center and end sections. The faces of the end sections are oriented generally perpendicular to an axis of the center section thereby forming an H-bar core. The H-bar core is located inside a plastic coilform cup, with the sides of the cup generally conforming to the shape of the core. Permanent magnets for biasing the H-bar core are located at opposite ends of the coilform cup adjacent the end sections of the core. The linearity coil conductor turns are wound around the coilform cup over the center section of the H-bar core.
