Figure 2.
The image depicts an interior view of a cylindrical structure, illustrating several components. The Upper flange is located at the top, while a Rubber membrane is positioned below it. The Base plate is at the bottom and shows a circular shape with a central hole. An L-shaped steel ring is visible along the inner walls, and a ring-sandwich component is located along the lower edge. The components are clearly marked with labels to indicate their specific functions within the structure. The layout allows clear observation of how these parts fit together.Photo of the membrane package under vacuum pressure
