摘要

1352778 Measuring thickness of layers electrically B ZUMBACH [trading as ZUMBACH ELECTRONIC-AUTOMATIC 19 April 1971 [11 March 1970] 32829/73 Divided out of 1352777 Heading G1N The description is as described in Specification 1352777 but the claims are directed to the construction of the measuring head which enables measurements of the thickness of dielectric layers on elongate metallic objects to be made independant of the precise positioning of the object with respect to the measuring head.
