Abstract

1,266,222. Paper-making apparatus. INDUSTRIAL NUCLEONICS CORP. 17 Feb., 1969 [16 Feb., 1968 (2)], No. 38414/71. Divided out of 1,266,221. Heading D2A. [Also in Division G3] This specification is identical with that of Specification 1,266,221 but the claims are directed to a system in which measurements of a property made on the same longitudinal portions of a travelling sheet of material before and after treatment are utilised to determine the proportion of the measurement before treatment which can respond to treatment, a signal corresponding to this proportion being stored periodically and a function of each stored signal and the next measurement before treatment is derived and utilised for control. purposes.
