Abstract

525,761. Alloys. WATSON, F. (Aktiebolaget Milo). Feb. 28, 1939, No. 6562. [Class 82 (i)] [Also in Group XXVI] A rotary compressor has parts made of a metallic material having a co-efficient of thermal expansion considerably lower than that of iron in the range 50‹-300‹C. The material may be a nickel-iron alloy, 32-40 per cent. nickel. Specifications 464,475 and 523,741, [both in Group XXVI], are referred to.
