摘要： The present invention provides an improved method of manufacturing a rupture disk and specifically of forming a score on a rupture disk. The method of the present invention includes the rotating of a rupture disk blank relative to an electrical discharge machining or "EDM" cutting wire and the simultaneous moving of the EDM cutting wire toward the axis of the disk while maintaining the wire in a selected position such as generally parallel to the disk peripheral skirt or flange. The rotation of the disk and the movement of the EDM wire can be precisely controlled with the motion system of a commercially available EDM machine. With the present invention, a precise score is cut a partial distance through the disk thickness and preferably on the convex side of the dome, near the transition from the dome to the flange and in a generally "c" shaped pattern. The formed score creates a pattern of weakness so that the disk will open in either of the forward or reverse buckling direction. Score patterns other than the "c" shaped pattern could be cut.

摘要： A rupture disk is provided for relieving pressure between the interior of a battery box and the exterior of the battery box, the box having an outlet opening. The apparatus includes a first layer that provides a gasket which abuts the battery box, the gasket having a central opening which aligns with the battery box opening. A second layer is in the form of a reverse buckling disk having a disk flange, a domed portion and a weakened portion on the dome that defines a disk burst pressure, the second layer having concave and convex sides. A third layer that is an outlet ring that sandwiches the second layer in between the first and the third layer layers, the outlet ring having a central opening surrounded by an edge. A plurality of teeth on the third layer extend from said edge inwardly a distance. A plurality of tabs are provided on the first and third layers, said tabs including circumferentially spaced apart tabs on each of said first and third layers, each tab having a tab opening, said tabs generally aligning so that a fastener can be passed through the tab openings of the first layer and the third layer. The third layer is attached to the second layer which is a metal disk by means of spot weld around the disk flange and the first layer attached to the metal disk by means of an adhesive thus forming a rupture disk assembly. The fasteners affix this rupture disk assembly to the box. The second layer is generally circular and surrounded by the fasteners. The teeth are positioned on the concave side of the second layer. In a preferred embodiment, the teeth do not extend so far inwardly that they extend inwardly beyond the weakened portion or score. From any radial line extending from the center of the layers, the weakened portion is reached before any tooth, the teeth thus being spaced radially a distance equal to or greater than the weakened portion or score.
