Abstract
1295342 Measuring boom bending moments electrically WARNER & SWASEY CO 4 Feb 1970 [14 Feb 1969] 22366/72 Divided out of 1295341 Heading G1N A boom assembly as disclosed in parent Specification 1295341 (Division G1) is described but the claims are directed to a boom having a plurality of telescoping sections 16-20; means for moving the telescoping sections relative to each other to vary the length of the boom, means for varying the angle of the boom and circuits producing a signal representative of a bending moment in the boom the circuits including means for varying the signal in response to changes in boom length and boom angle.
