Abstract

1,003,766. Valves. ROTORK ENGINEER ING CO. Ltd. May 22, 1962 [May 23, 1961] No. 49398/64. Divided out of 1,003,761 Heading F2V. [Also in Division H2] The subject-matter is substantially the same as that of Specification 1,003,761 but the claims are concerned with the friction drive between the shaft 17 and the hollow threaded spindle 25. Specifications 842,581, 865,565, 939, 353, 1,003,764 and 1,003,765 also are referred to.
