Rockwell International Corp’s second-quarter figures were strained slightly because profits at its semiconductor systems business were down 13% from a year earlier as a result of the transition to making new K56flex modem chip sets. It expects shipments of the chip sets to reach one million a month by the end of the current quarter. However, second quarter revenue growth was led by the industrial automation unit, where earnings were up 21% from last year; automation sales rose 10%, and avionics and communications earnings were more than double the year-earlier results, it said. Second-quarter net income from continuing operations – Rockwell recently announced the spinoff of its automotive business (CI No 3,122) and last August sold its aerospace and defense business (CI No 2,969) – was up 28% at $155m on revenue up 6% at $1.9bn.
