Abstract:
A safety cabinet for storing flammable liquids is provided with a flame arresting vent. The flame arresting vent or “flame arrestor” allows flammable vapors inside the cabinet to leave the cabinet's interior but prevents flame from flowing into the cabinet's interior from outside the cabinet.

Claim (Index 6):
The flame arrestor for a safety cabinet of  claim 2 , wherein each wire mesh layer comprises:\n a first set of substantially evenly-spaced-apart, substantially parallel metal wires coupled to a second set of substantially evenly-spaced-apart, substantially parallel metal wires, the wires of the first set of wires crossing the wires of the second set of wires at a first predetermined angle, the crossed first and second sets of wires defining a set of wire parallelograms each wire parallelogram of the set of wire parallelograms having substantially congruent opposite sides defining a substantially parallelogram-shaped opening having an open area, which is sufficient to allow gaseous molecules to pass there through, the metal wires being corrosion resistant; wherein a predetermined side of the wire parallelograms comprising the first wire mesh layer are oriented at a first predetermined angle relative to horizontal; wherein the same predetermined side of the wire parallelograms comprising the second wire mesh layer are oriented at a second predetermined angle relative to horizontal such that wires of the second wire mesh layer at least partially occlude the parallelogram-shaped openings of the first wire mesh layer; wherein the same predetermined side of wire parallelograms comprising the intermediate wire mesh layer are oriented at a third predetermined angle relative to horizontal such that wires of the intermediate wire mesh layer at least partially occlude the parallelogram-shaped openings of the first and second wire mesh layers; and wherein the first, second and third predetermined angles are selected such that, at least some molecules of a gas passing through the plurality of wire mesh layers, will follow a path through the plurality of wire mesh layers, which is at least partially boustrophedonic.
