Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
122 words
A container and means for oscillating said container, said container being provided with walls having openings for receiving articles to be treated in electroplating baths and being positioned parallel to the plane containing the axis of oscillatory movements, said walls being further provided with at least one saw-toothed projection which projects forward toward one of the circulating directions of the articles, the container walls being asymmetrically shaped relative to the plane containing the axis of movement of the container, oppositely positioned sections of the container walls being positioned parallel to the plane containing the axis of oscillatory movement, said axis being located in the center position of the container, and wherein one section of the walls is higher than the opposite section.
Claim 2
Dependent Claim
122 words
A container and means for oscillating said container, said container being provided with walls having openings for receiving articles to be treated in electroplating baths and being positioned parallel to the plane containing the axis of oscillatory movements, said walls being further provided with at least one saw-toothed projection which projects forward toward one of the circulating directions of the articles, the container walls being asymmetrically shaped relative to the plane containing the axis of movement of the container, oppositely positioned sections of the container walls being positioned parallel to the plane containing the axis of oscillatory movement, said axis being located in the center position of the container, and wherein one section of the walls is higher than the opposite section.
Claim 3
Dependent Claim
129 words
A container and means for oscillating said container, said container being provided with walls having openings for receiving articles to be treated in electroplating baths and being positioned parallel to the plane containing the axis of oscillatory movements, said walls being further provided with at least one saw-toothed projection which projects forward toward one of the circulating directions of the articles, oppositely positioned sections of the container walls being positioned parallel to the plane containing the axis of oscillatory movement, one section of the walls being higher than the opposite section, said axis being disposed along said higher section of the walls, and wherein said higher section of the walls is shaped as a sloping plane, over which the articles can be tilted to pass into the adjacent container.
Claim 4
Dependent Claim
129 words
