Patent CA-2130038-A1 (CA)
Title: Multi-purpose dome structure and the construction thereof
Inventor: DYKMANS MAXIMILLIAAN J
IPC: E04B1/32
Filed: 1994-08-12
Abstract: An improved dome structure on a base is disclosed comprising,  in the preferred embodiment,  of a membrane sandwiched between layers of rigidifying material such as shotcrete or reinforced composite which also serve to embed  radial   wires   and  circumferential   tensioned prestressing.  Various types of circumferential tensioned prestressing can be applied to minimize bursting stresses and can consist of steel wire as well as fiber or steel-reinforced tape.  Further layers of rigidifying material can then be applied over the circumferential prestressing as a final protection and cover.   The radial wires can contain spacers or hooks to preclude the circumferential prestressing from riding up on the structure.  The lower portion of the dome can include a reverse curvature to minimize  stresses  and  stabilize  the  structure.    The rigidifying  material  may  be  composite  which  can  be hardened by light curing.   A second outer membrane can also be used for weather protection.

Title: Inspection of translucent containers
Inventor: NICKS TIMOTHY J
IPC: G01P15/08
Filed: 1994-09-15
Abstract: Apparatus for detecting checks in the sidewall of a translucent container (22) that includes a light source (24) for illuminating an elongated strip of the container sidewall parallel to the central axis of the container in such a way that illumination rays are incident at any point of the strip from multiple differing angles. A camera (50) is positioned externally of the container for receiving light reflected by checks in the illuminated strip, and electronic circuitry (52) is coupled to the camera for detecting checks in the container as a function of such reflected light. Since the light rays at any point in the elongated illuminated strip on the container sidewall are incident from multiple differing angles, planar checks and split seams in the container sidewall that are not precisely vertical in orientation will have a greater chance of reflecting light energy from the source onto the camera.
