Abstract

1353979 Wire fabrics UGINE KUHLMANN 3 Sept 1971 [4 Sept 1970] 41220/71 Heading D1K [Also in Division B1] Permeable sheet material is supported on an "articulated cloth" comprising a plurality of parallel helices 1, the helices being formed of a refractory metal alloy and adjacent helices being 'screwed' through one another so that each helix is interlocked with the adjacent helix. The helices are stretched within a frame with an extension of aprox 2% in length in all directions in the plane of the array.
