Appeal No. 1996-3675
Application No. 08/259,933
Claims 1 and 16 are illustrative of the claims on appeal
and are reproduced below:
1. A reference electrode construction for an
electrically powered marine propulsion unit
corrosion protection system, said reference
electrode comprising an electrode wire having an
outer surface formed of material which is soluble in
a body of water in which said reference electrode is
immersed, an elongated surrounding protective
covering having a V-shaped portion at least
partially enclosing a V-shaped section of said
electrode wire and defining a small volume
therebetween, said outer surface material of said
electrode wire being sufficiently dissolvable in the
volume of water between said protective covering and
said electrode wire to produce a saturated solution
of said outer surface material when said reference
electrode is placed in the body of water, and a
plurality of fluidic openings which open into said
small volume defined between said electrode wire and
said covering.
16. A reference electrode construction for an
electrical corrosion protection system adapted for
use with a marine propulsion unit, said reference
electrode comprising an electrode wire having an
outer surface of material that is soluble in a body
of water in which said reference electrode is
immersed, an elongated surrounding protective
covering which encloses at least a portion of the
electrode wire and defines a small space
therebetween, said outer surface material of said
electrode wire being sufficiently dissolvable in the
volume of water between said protective covering and
said electrode wire to produce a saturated solution
of said outer surface material when said reference
electrode is placed in the body of water, and a
plurality of fluidic openings which open into the
