Abstract

562,488. Testing roughness of surfaces. BROWN & SONS (HUDDERSFIELD), Ltd., D., and STRINGER, J. E. C. Jan. 12, 1943, No. 537. [Class 106 (ii)] To enable curved surfaces to be tested for roughness without producing a hump-backed curve, the rider e of a stylustracer gauge supports the tracer head c through corresponding spherical surfaces el, c<1>, the centre of curvature of the surfaces being coincident with the mean position of the stylus point a<1>.
