Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 88 words
A storage battery plate comprising: a grid formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass; a grid of lead bars recessed within said channels; active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed; and electrolyte permeable fibrous mats covering said grid on both sides said mats being firmly attached to said exposed edges of plastic strips and plastic cross-connections.
Claim 2
Dependent Claim 88 words
A storage battery plate comprising: a grid formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass; a grid of lead bars recessed within said channels; active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed; and electrolyte permeable fibrous mats covering said grid on both sides said mats being firmly attached to said exposed edges of plastic strips and plastic cross-connections.
Claim 3
Dependent Claim 35 words
The plate of claim 1, wherein the lengths of the plastic cross-connections are related to the lengths of the plastic strips in the ratio of from about 1 : 4 to about 1 : 25.
Claim 4
Dependent Claim 21 words
The plate of claim 1, wherein the plastic strips and cross-connections are thickened at their edges atttached to the fibrous mats.
Claim 5
Dependent Claim 12 words
The plate of claim 1, wherein the fibrous mats consist of batting.
Claim 6
Dependent Claim 14 words
The plate of claim 1, wherein the fibrous mats are welded to said edges.
Claim 7
Dependent Claim 18 words
The plate of claim 1, wherein the plastic strips and cross-connections consist of a coarse pored foam material.
Claim 8
Dependent Claim 25 words
The plate of claim 1, wherein the plastic strips are formed of interdigitated segments extending into the mass alternately from opposite surfaces of said mass.
Claim 9
Dependent Claim 24 words
The plate of claim 1, wherein the lead bars are substantially centered within said channels and surrounded on all sides by said active mass.
Claim 10
Dependent Claim 123 words
A storage battery plate assembly comprising: a plurality of grids formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass; a plurality of grids of lead bars, each said grid being recessed within the channels defined by one of said plastic grids; active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed; and electrolyte permeable fibrous mats covering each said grid on both sides and firmly attached to said exposed edges of plastic strips and plastic cross-connections, different ones of said grids being placed adjacent each other to form the plates of said assembly, without intervening separator.
Claim 11
Dependent Claim 123 words
A storage battery plate assembly comprising: a plurality of grids formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass; a plurality of grids of lead bars, each said grid being recessed within the channels defined by one of said plastic grids; active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed; and electrolyte permeable fibrous mats covering each said grid on both sides and firmly attached to said exposed edges of plastic strips and plastic cross-connections, different ones of said grids being placed adjacent each other to form the plates of said assembly, without intervening separator.
Claim 12
Dependent Claim 17 words
The assembly of claim 9, wherein said mats form the separators between adjacent plates of said assembly.
Claim 13
Dependent Claim 15 words
The assembly of claim 10, wherein adjacent ones of said plates are of different polarity.
Claim 14
Dependent Claim 92 words
A storage battery plate comprising: a grid formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass; a grid of lead bars recessed within said channels; active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed; and electrolyte permeable mats formed of porous separator material covering said grid on both sides said mats being firmly attached to said exposed edges of platic strips and plastic cross-connections.
Claim 15
Dependent Claim 92 words
A storage battery plate comprising: a grid formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass; a grid of lead bars recessed within said channels; active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed; and electrolyte permeable mats formed of porous separator material covering said grid on both sides said mats being firmly attached to said exposed edges of platic strips and plastic cross-connections.
