Abstract

1327827 Vertical air speed instrument SMITHS INDUSTRIES Ltd 28 April 1972 [30 April 1971] 12303/71 Heading G1L The subject matter of this Specification is substantially the same as that of Specification 1327828 but the claims concern the provision in the vertical speed instrument of a pressure responsive device for varying the degree of retardation provided by the air-flow restrictor assembly, independence upon altitude.
