Abstract
Abstract Pile structure for use in batteries, particularly seawater batteries. The pile structure comprises one or more plates (2) which are separated by separator plugs (3) which extend via through-holes (5) from surface to surface of each plate. The separator plugs (3) are formed to integral spacer heads (33) beyond one surface of each plate. A continuous or intermittent band (30) is formed around the edge of each plate, and is provided with projections (36) which extend beyond that one surface of each plate, coextensively with the spacer heads. The separator plugs (33) and bands (30) may be formed by injection moulding process. The openings between the projections (36) permit passage of seawater. Another application for the pile structure is as a heat exchanger.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
99 words
A pile structure comprising one or more plates (2) characterized by separator plugs (3) extending through each said plate (2) from surface to surface, said plugs continuing beyond one surface of each plate to terminate in uniform integral spacer heads (3), and a continuous or intermittent band (30) enclosing the edge of each said plate said band (30) and having projections (36) extending beyond the said one surface of the plate, coextensively with said spacer heads (33), whereby said spacer heads (33) and said projections (36) would determine the spacing between each said plate (2) and another contiguous object.
Claim 2
Dependent Claim
99 words
A pile structure comprising one or more plates (2) characterized by separator plugs (3) extending through each said plate (2) from surface to surface, said plugs continuing beyond one surface of each plate to terminate in uniform integral spacer heads (3), and a continuous or intermittent band (30) enclosing the edge of each said plate said band (30) and having projections (36) extending beyond the said one surface of the plate, coextensively with said spacer heads (33), whereby said spacer heads (33) and said projections (36) would determine the spacing between each said plate (2) and another contiguous object.
Claim 3
Dependent Claim
66 words
A pile structure according to Claim 1 wherein: each said plate (2) is formed with discrete and separated holes (5) extending through said plate from surface to surface thereof, said separator plugs (3) are made of a plastic substance that is molded into said holes (5), and said band (30) is made of plastic substance which is molded onto the edge of each said plate (2).
Claim 4
Dependent Claim
19 words
A pile structure according to Claim 1 or 2 wherein said separator plugs have spacer heads on both ends.
Claim 5
Dependent Claim
104 words
A pile structure according to Claim 2 wherein: said separator plugs (3) each have a retainer head (31) on the end remote from said spacer head (33), said retainer heads being countersunk into said plate, with all spacer heads in each plate extending from the same surface of that plate; said one or more plates (2) have perimeter areas of reduced thickness on to which said bands (30) are molded; and each said band at such plate areas of reduced thickness has an exterior surface flush with the surface of the plate on the side of the plate having the said plug retainer heads.
Claim 6
Dependent Claim
31 words
A pile structure according to Claim 4 wherein said one or more plates are made of a substance having low thermal resistivity whereby said structure has utility as a heat exchanger.
Claim 7
Dependent Claim
37 words
A pile structure according to Claim 4 wherein: said one or more plates are made of a voltaic substance; and said plugs and band are made of a dielectric which is resistant to ionization and galvanic action.
Claim 8
Dependent Claim
74 words
A pile structure according to Claim 4 wherein: said one ore more plates each include two or more laminae (22,23,24) of different voltaic substances which cooperate in the presence of an electrolyte to create a voltaic cell; and said plugs (3) with said retainer heads (31) and said spacer heads (33) at least in part secure said two or more laminae of each said one or more plates together to form each said plate.
Claim 9
Dependent Claim
71 words
A pile structure according to Claim 7 wherein: there are a plurality of uniformly spaced plates; and said plurality of plates (2) are stacked parallel to one another in surface of surface relationship and oriented with said spacer heads (33) of said plugs (3) in a common direction so that each interval between plates is determined by a single set of spacer heads and said projections (36) on said bands (30).
Claim 10
Dependent Claim
28 words
A pile structure according to Claim 8 wherein said plurality of plates are joined together into a pile by adhesion between said bands to form a primary battery.
Claim 11
Independent Claim
77 words
A method of producing a pile structure having a series of uniformly spaced plates comprising the steps of preparing a number of individual plates, characterized by placing a number of holes (15) through each of said plates from surface to surface according to a predetermined pattern; and injection molding plastic separator plugs (3) into said holes in each plate, said plugs having spacer heads (33) of predetermined size and shape protruding from one face of each plate.
Claim 12
Independent Claim
77 words
A method of producing a pile structure having a series of uniformly spaced plates comprising the steps of preparing a number of individual plates, characterized by placing a number of holes (15) through each of said plates from surface to surface according to a predetermined pattern; and injection molding plastic separator plugs (3) into said holes in each plate, said plugs having spacer heads (33) of predetermined size and shape protruding from one face of each plate.
Claim 13
Dependent Claim
40 words
A method according to Claim 10 further comprising the additional steps of: stacking said number of plates in surface to surface relationship separated by said spacer heads to form a pile; and securing said plates together in their stacked relationship.
Claim 14
Dependent Claim
31 words
A method according to Claim 11 further comprising the additional step of injection molding a plastic band (30) around at least a substantial part of the peripheral edge of each plate.
Claim 15
Dependent Claim
46 words
A method according to Claim 11 wherein the step of injection molding plastic separator plugs in the holes in each plate, also includes the simultaneous injection molding of a plastic band (30) around at least a substantial part of the peripheral edge of each said plate.
Claim 16
Dependent Claim
60 words
A method according to Claim 13 wherein the step of placing a number of holes includes the shaping of said holes (5) to enlarge the holes at the face of each plate remote from said one face to cause said plugs to be molded with countersunk retainer heads (31) on the end of said plugs opposite said spacer heads (33).
