Abstract
Abstract An electrochemical stem drilling apparatus hollow-tube electrode mounting system includes a pair of clamp members (52,54), each positionable adjoining a feed head (12) on either side of the plurality of hollow-tube electrodes (14) and each having a plurality of elongated grooves to more securely hold the hollow-tube electrodes in a predetermined orientation and to provide an increased area of electrical contact with the electrodes. A sealing layer (32) of silicon or other comparable material extends around each of the electrodes where they pass from a feed head of the apparatus preventing electrolyte leakage.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
127 words
An electrode mounting system for use with the electrochemical stem drilling apparatus employing a plurality of hollow-tube electrodes, an electrolyte feed head (12) with one or more openings for receiving an end of each of the plurality of hollow-tube electrodes (14) and feeding a fluid electrolyte (24) into each of the hollow-tube electrolyte ends (14a), comprising: a first clamp member (52) adapted for positioning adjoining the one or more feed head openings and against a first side of each of said plurality of hollow-tube electrodes; and a second clamp member (54) adapted for positioning also adjoining the one or more feed head opening and against an opposing side of each of said plurality of hollow-tube electrodes fixing said plurality of hollow-tube electrodes against said first clamp member.
Claim 2
Dependent Claim
127 words
An electrode mounting system for use with the electrochemical stem drilling apparatus employing a plurality of hollow-tube electrodes, an electrolyte feed head (12) with one or more openings for receiving an end of each of the plurality of hollow-tube electrodes (14) and feeding a fluid electrolyte (24) into each of the hollow-tube electrolyte ends (14a), comprising: a first clamp member (52) adapted for positioning adjoining the one or more feed head openings and against a first side of each of said plurality of hollow-tube electrodes; and a second clamp member (54) adapted for positioning also adjoining the one or more feed head opening and against an opposing side of each of said plurality of hollow-tube electrodes fixing said plurality of hollow-tube electrodes against said first clamp member.
Claim 3
Dependent Claim
42 words
An electrode mounting system according to claim 1 wherein each of said first and second clamp members (52,54) contacts each of said plurality of hollow-tube electrodes (14) over a length at least greater than 13 mm, or preferably greater than 25 mm.
Claim 4
Dependent Claim
37 words
An electrode mounting system according to claim 1 or 2 further comprising: an electrode coupling between at least one of said first and second clamp members and one side of an electric power source of the apparatus.
Claim 5
Dependent Claim
40 words
An electrode mounting system according to any preceding claim further comprising: a plurality of grooves (58) spaced along a surface of the first clamp member (52), each groove sized to receive and contact the first side of a hollow-tube electrode.
Claim 6
Dependent Claim
51 words
An electrode mounting system according to claim 4 further comprising: a like plurality of grooves along a surface of a second clamp member (54), each sized and positioned along said surface to receive and contact the opposing side of a hollow-tube electrode received in a groove of the first clamp member.
Claim 7
Dependent Claim
27 words
An electrode mounting system according to claim 4 or 5 further comprising: holder means (40) for holding said first and second clamp members against said hollow-tube electrodes.
Claim 8
Dependent Claim
29 words
An electrode mounting system according to any one of claim 4 to 6 wherein at least one of the clamp members is fixedly attached to said feed head means.
Claim 9
Dependent Claim
24 words
An electrode mounting system according to any one of claims 4 to 7 wherein said grooves are at least about 25 mm in length.
Claim 10
Dependent Claim
55 words
An electrode mounting system according to any preceding claim further comprising: a layer of sealing material forming seals (32) completely surrounding each of said plurality of hollow-tube electrodes (14) and extending between each of said plurality of electrodes and each of said one or more feed head means openings (16) completely covering any gap therebetween.
Claim 11
Dependent Claim
69 words
An electrode mounting system according to claim 9, wherein said layer of sealing material forms an electrolyte leak proof seal between said one or more openings of the feed head means and each of said plurality of hollow-tube electrodes and completely around each of said hollow-tube electrodes, the layer being formed from a material castable and curable at room temperature essentially without contraction from said openings and said electrodes.
