Abstract
Abstract A porous metal panel for use in distributing deicing fluid onto the leading edge of a surface, such as the wings and tail of an airplane or other vehicle, that requires protection against ice. The porous metal panel includes a porous outer metal plate, a nonporous inner metal plate, a porous metal membrane having a porosity finer than the porosity of said porous outer plate disposed on the inner surface of said porous outer plate, a separator member comprising a sheet of metal wire mesh disposed between said metal membrane and said inner nonporous metal plate, said separator member having a porosity coarser than the porosity of said porous metal membrane, the peripheral edges of said inner plate and membrane being bonded in a fluidtight condition to the outer plate to enclose said separator member and form a fluid chamber, and means for connecting said fluid chamber to a source of pressurized deicing fluid for admission of said fluid into said chamber for distribution through said membrane and outer porous plate onto said surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A porous metal panel, for attachment to a surface to form part of said surface, for distributing deicing fluid onto said surface comprising: a. a porous outer metal plate; b. a nonporous inner metal plate; c. a porous metal membrane, having a porosity finer than the porosity of said porous outer plate, disposed on the inner surface of said porous outer plate; d. a separator member comprising a sheet of metal wire mesh disposed between said metal membrane and said nonporous metal plate, and said separator member having a porosity coarser than the porosity of said porous metal membrane; e. the entire peripheral edges of said inner plate and membrane being bonded in a fluidtight condition to the outer plate to enclose said separator member and form a fluid chamber; and, f. means for connecting said fluid chamber to a source of pressuriZed deicing fluid for admission of said fluid into said chamber for distribution through said membrane and outer porous plate onto said surface.
Claim 2
Dependent Claim
165 words
A porous metal panel, for attachment to a surface to form part of said surface, for distributing deicing fluid onto said surface comprising: a. a porous outer metal plate; b. a nonporous inner metal plate; c. a porous metal membrane, having a porosity finer than the porosity of said porous outer plate, disposed on the inner surface of said porous outer plate; d. a separator member comprising a sheet of metal wire mesh disposed between said metal membrane and said nonporous metal plate, and said separator member having a porosity coarser than the porosity of said porous metal membrane; e. the entire peripheral edges of said inner plate and membrane being bonded in a fluidtight condition to the outer plate to enclose said separator member and form a fluid chamber; and, f. means for connecting said fluid chamber to a source of pressuriZed deicing fluid for admission of said fluid into said chamber for distribution through said membrane and outer porous plate onto said surface.
Claim 3
Dependent Claim
45 words
A porous metal panel as defined in claim 1, wherein: a. the porosity of said membrane is of such a micron rating relative to said fluid so as to block flow of said fluid through said membrane when pressure on said fluid is cut off.
Claim 4
Dependent Claim
34 words
A porous metal panel as defined in claim 1, wherein: a. said metal outer plate, said metal membrane, said metal wire mesh separator and said metal inner plate are each made from stainless steel.
Claim 5
Dependent Claim
30 words
A porous metal panel as defined in claim 1, wherein: a. said peripheral edges of said inner plate and membrane are bonded to said outer plate by heat and pressure.
Claim 6
Dependent Claim
41 words
A porous metal panel as defined in claim 4, wherein: a. said metal outer plate, said metal membrane, said metal wire mesh separator and said metal inner plate are bonded together by heat and pressure to form a solid pack construction.
Claim 7
Dependent Claim
32 words
A porous metal panel as defined in claim 1, wherein: a. said peripheral edges of said inner plate and membrane are bonded to said outer plate by being electron beam welded together.
Claim 8
Dependent Claim
41 words
A porous metal panel as defined in claim 6, wherein: a. said metal outer plate, said metal membrane, said metal wire mesh separator and said metal inner plate are bonded together by heat and pressure to form a solid pack construction.
