Open the CIPO recordAbstract From the Canadian patent
The invention teaches a method of spacing the elements of a flame arrestor and securing that spacing in a simple and economical manner. A shim is used to space the elements, the elements are welded together And the shim is removed. This leaves a controlled flow path between the elements but the spacing is such to prevent the propagation of a flame through the arrestor.
