Abstract
Abstract An end connector for a filter press cell disassociates the mechanical sealing function from the primary electrical connection. The connector includes a boss extension having an aperture formed therein for tightening the connector between the boss and boss extension. The present invention is adaptable for use as an end connector for either the anode or the cathode.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
In a bipolar electrolytic filter press cell of the type having an anode and a cathode, each electrode having a boss member associated therewith and a central web interposed between the anode and cathode, an improved end connector therefor, comprising: a. a boss extension member which matingly engages the surface of the boss member remote from an associated electrode, b. a pressure collar mounted on the boss extension member, and c. means interconnecting the boss member and the boss extension member, such that the connector defines a liquid-gas seal independent of an electrical connection.
Claim 2
Dependent Claim
94 words
In a bipolar electrolytic filter press cell of the type having an anode and a cathode, each electrode having a boss member associated therewith and a central web interposed between the anode and cathode, an improved end connector therefor, comprising: a. a boss extension member which matingly engages the surface of the boss member remote from an associated electrode, b. a pressure collar mounted on the boss extension member, and c. means interconnecting the boss member and the boss extension member, such that the connector defines a liquid-gas seal independent of an electrical connection.
Claim 3
Dependent Claim
48 words
The end connector of claim 1 wherein the boss extension member includes a partial bore having an internal thread, the boss includes a partial bore having an internal thread, the partial bores being in registry, and the interconnecting means comprises a threaded fastener disposed in the partial bores.
Claim 4
Dependent Claim
14 words
The end connector of claim 2 wherein the boss is associated with the anode.
Claim 5
Dependent Claim
34 words
The end connector of claim 1 wherein the boss extension member includes means for electrically connecting the electrode thereto, the means being provided at the end of the boss opposite the boss engaging end.
Claim 6
Dependent Claim
52 words
The end connector of claim 1 wherein the boss extension member has an internally threaded partial bore formed therein, the boss has an internal throughbore formed therethrough and being in registry with the partial bore and the interconnecting means comprises a threaded fastener extending through the throughbore and into the partial bore.
Claim 7
Dependent Claim
26 words
The end connector of claim 5 wherein the boss member is associated with the cathode, the threaded fastener extending through an opening provided in the cathode.
Claim 8
Dependent Claim
18 words
The end connector of claim 1 wherein the pressure collar is threadably mounted on the boss extension member.
Claim 9
Dependent Claim
30 words
The end connector of claim 1 wherein the boss extension member extends at least partially through an aperture formed in the web associated with the last cell of the module.
