Abstract: A container inspection apparatus and method measures both warp and off-level of an annular sealing surface of a container. The apparatus preferably has a warp gauge device and an off-level gauge device suspended over a container support and base by at least one column for the warp gauge device and a pillar for the off-level gauge device. When measuring for warp, the off-level gauge device is constructed and arranged to pivot clear of the warp gauge device, and vice-versa when measuring for off-level. The container preferably is held laterally or radially in place by two V-bracket assemblies, and vertically in place by a container support. The V-bracket assemblies are adjustable vertically to accommodate containers of differing diameters and heights.

Abstract: A goniometric sensor (1) for measuring the relative rotation of two objects (20,25) comprising a flexible elongated element (2) whose respective ends are connected to the two objects (20, 25) and during whose bending the length variation ?L is determined of one of the lines (15) not located at the neutral axis (10). This length variation ?L is directly proportional to the relative rotation (?) between the two bodies (20, 25) multiplied for the eccentricity (e) of the line (15) with respect to the neutral axis (10). Therefore, it is possible to determine easily the relative rotation (?) by knowing the length L and the eccentricity (e) with respect to the neutral axis 10, and measuring the length variation ?L of the line, for example by measuring the movement of the end of a cable located in a hole that contains the line.
