<p>In many areas of technology where steel is used it is important to know how much hydrogen is in the steel. In the complete Specification of our British Patent No: 2,312,279 (P1448) there is described and claimed a hydrogen detection system including a collection enclosure to be placed against the steel surface to be tested and for gathering into a carrier gas passed therethrough hydrogen emanating from that surface. The system is satisfactory for use in connection with flat surfaces, but less so for surfaces that are not flat. The present invention seeks to deal with the conformity problem by making the collector (12) a flexible plate (21) on the receptor face of which are constructed raised grooves or high spots, which may be presented approximately parallel to an approximately flat surface or approximately tangential to a curved surface, and which form guiding channels (201) along which hydrogen emanating from the surface (11) underlying the plate can be drawn and sent to an associated detector system (15). <IMAGE></p> |
