Abstract
Abstract A porous dielectric oxide film-forming metal anode capacitor is provided with an anode riser means that is able to absorb energy by deforming or flexing when subjected to compressive forces such as the forces resulting from a crimping operation in the construction of the capacitor. The anode riser means comprises one or more continuous lengths of metal with at least a portion of one of the lengths in the shape of a bight.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
A capcitor comprising a housing having an open end, a sintered dielectric oxide film-forming metal anode means having a myriad of intercommunicating voids, a liquid type electrolyte contacting the anode means, rigid means closing the open end of the housing and edges of the housing compressively acting on the rigid means and thereby on the anode means, resilient means interposed between the anode means and the rigid means, surfaces of the resilient means contacting the anode means and the rigid means to help maintain the anode means in the fixed spatial relationship relative to the housing, and anode riser means capable of absorbing compressive forces projecting through the resilient means, the anode riser means having two distal ends and comprising at least one continuous length of metal and at least a portion of at least one length in the shape of a bight, the first distal end of the anode riser means in electrical contact with the anode means and the second distal end providing means for external termination of the anode means.
Claim 2
Dependent Claim
173 words

Claim 3
Dependent Claim
15 words
The capacitor of claim 1, wherein the anode riser means has a substantially C-shaped portion.
Claim 4
Dependent Claim
15 words

Claim 5
Dependent Claim
25 words
The capacitor of claim 1, wherein the anode riser means contains two lengths of metal connected together and forming at least two substantially right angles.
Claim 6
Dependent Claim
