The mounting plate is mounted to an internal surface of an air hose. Assay apparatus comprises a solid phase on which is immobilised the analyte or an antibody specific for the analyte, a reporter composition comprising a thermostable adenylate kinase coupled to an antibody specific for the analyte, and ADP plus associated reagents for conversion of ADP into ATP by thermostable adenylate kinase. The adhesive layer is adjacent to the absorptive layer. Also, a method of production of a high strength \u03b1+\u03b2 titanium alloy pipe comprising cold forming a high strength \u03b1+\u03b2 titanium alloy plate of a wall thickness of at least 6 mm into a tubular shape by the U-O method or press-bending method and welding together the abutted plate edges.
