Abstract
Abstract An explosive-suppressive mass comprises layers of expanded metal of which each layer is arranged in a selected orientation so that its mesh strands are inclined with respect to the mesh strands of the layers adjacent thereto. This gives economic and other advantages in the manufacture of the anti-explosive materials.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
63 words
A method of forming an explosion-suppressive mass comprising providing a lamina of expanded metal consisting of flat mesh strands defining diamond-shape mesh openings, the strands each being inclined at the same angle to the general plane of the lamina, and layering the lamina to form a multiple-layer mass, the strands of each layer being inclined oppositely to the strands in each adjacent layer.
Claim 2
Independent Claim
63 words
A method of forming an explosion-suppressive mass comprising providing a lamina of expanded metal consisting of flat mesh strands defining diamond-shape mesh openings, the strands each being inclined at the same angle to the general plane of the lamina, and layering the lamina to form a multiple-layer mass, the strands of each layer being inclined oppositely to the strands in each adjacent layer.
Claim 3
Dependent Claim
45 words
A method as claimed in claim 1 wherein said layering comprises coiling the lamina into a cylindrical bale and including interleaving an auxiliary lamina with the first-mentioned lamina, the auxiliary lamina consisting of mesh strands inclining oppositely to the mesh strands of the first-mentioned lamina.
Claim 4
Dependent Claim
46 words
A method as claimed in claim 1 wherein the lamina is a continuous length of rotary slit expanded metal consisting of mesh strands inclined at the same angle with respect to the transverse direction, and wherein said layering comprises fan-folding the metal about transverse fold lines.
Claim 5
Dependent Claim
63 words
A method as claimed in claim 1 wherein the lamina is a continuous length of rotary slit expanded metal consisting of mesh strands inclined at the same angle with respect to the transverse direction and including the steps of severing said length transversely into sections and rotating each alternate severed section about its transverse axis prior to stacking the sections one on another.
Claim 6
Dependent Claim
87 words
A method as claimed in claim 1 wherein the lamina is a continuous length of an expanded metal material selected from rotary slit expanded metal consisting of mesh strands inclined at the same angle to the transverse direction and reciprocating-cut expanded metal consisting of mesh strands inclined at the same angle to the longitudinal direction and including the steps of severing the length transversely into sections and rotating each alternate section through 180° in its own plane prior to stacking the sections one on top of another.
Claim 7
Dependent Claim
53 words
An explosion-suppressive mass comprising multiple layers of expanded metal, said expanded metal consisting of flat mesh strands defining diamond-shaped mesh openings, the strands each being inclined at the same angle to the general plane of the expanded metal, the strands in each layer being inclined oppositely to the strands in each adjacent layer.
Claim 8
Dependent Claim
53 words
An explosion-suppressive mass comprising multiple layers of expanded metal, said expanded metal consisting of flat mesh strands defining diamond-shaped mesh openings, the strands each being inclined at the same angle to the general plane of the expanded metal, the strands in each layer being inclined oppositely to the strands in each adjacent layer.
Claim 9
Dependent Claim
21 words
A mass as claimed in claim 6 constituted by at least two interleaved expanded metal layers coiled into a cylindrical bale.
Claim 10
Dependent Claim
21 words
A mass as claimed in claim 6 comprising discrete expanded metal pieces of similar shape stacked one on top of another.
Claim 11
Dependent Claim
59 words
A container for explosive fluids equipped internally with an expanded metal mass consisting substantially wholly of layers of expanded metal consisting of flat mesh strands defining diamond-shaped openings, each strand being inclined at the same angle to the general plane of the metal, and the strands of each layer being inclined oppositely to the strands in each adjacent layer.
Claim 12
Dependent Claim
59 words
A container for explosive fluids equipped internally with an expanded metal mass consisting substantially wholly of layers of expanded metal consisting of flat mesh strands defining diamond-shaped openings, each strand being inclined at the same angle to the general plane of the metal, and the strands of each layer being inclined oppositely to the strands in each adjacent layer.
Claim 13
Dependent Claim
79 words
A cylindrical container for explosive fluids equipped internally with a cylindrical bale comprising a cylindrically-coiled winding having a plurality of turns of two superimposed laminae of expanded metal, each lamina being constituted by flat mesh strands defining diamond-shaped mesh openings and each strand being inclined at the same angle to the general plane of the lamina, and wherein the strands in each turn of one lamina incline oppositely to the strands of each adjacent turn of the other lamina.
Claim 14
Dependent Claim
79 words
A cylindrical container for explosive fluids equipped internally with a cylindrical bale comprising a cylindrically-coiled winding having a plurality of turns of two superimposed laminae of expanded metal, each lamina being constituted by flat mesh strands defining diamond-shaped mesh openings and each strand being inclined at the same angle to the general plane of the lamina, and wherein the strands in each turn of one lamina incline oppositely to the strands of each adjacent turn of the other lamina.
