Abstract

670,484. Variable-pitch propellers. UNITED AIRCRAFT CORPORATION. Aug. 1, 1946 [Aug. 9, 1945], No. 20119/50. Divided out of 670,412. Drawings to Specification. Class 114. [Also in Group XXIX] The subject-matter of this Specification is identical with that described in Specification 670,412 but the claims are directed to the mechanism whereby, when both propellers are stationary, one propeller is unfeathered as a result of the unfeathering of the other propeller by auxiliary power means. Specifications 560,522 and 752/44 (as open to inspection under Sect. 91) also are referred to.
