Claims22
A force balance transmitter comprising a base plate means having a substantially flat upper surface, a primary unit detachably secured to said surface of said base plate means and having a primary pivot arm, a secondary unit detachably secured to said surface of said base plate means and having a secondary pivot arm, and means operatively interconnecting said primary arm and said secondary arm together, said means operatively interconnecting said primary arm and said secondary arm together comprising a bell crank flexure pivot means.
A force balance transmitter as set forth in claim 2 and including a pair of flexure arms disposed at substantially a right angle relative to each other and respectively being interconnected to said primary arm and said secondary arm, said bell crank flexure pivot means interconnecting said flexure arms together.
A force balance transmitter as set forth in claim 3 wherein the flexure arm interconnected to said primary arm forms part of a bias adjusting means.
A force balance transmitter comprising a base means, a primary unit carried by said base means and having a primary pivot arm, a secondary unit carried by said base means and having a secondary pivot arm, and a bell crank flexure pivot means operatively interconnecting said primary arm and said secondary arm together.
A method of making a force balance transmitter comprising the steps of forming a base plate means with a substantially flat upper surface, detachably securing a primary unit to said surface of said base plate means, detachably securing a secondary unit to said surface of said base plate means, and operatively interconnecting a primary arm of said primary unit to a secondary arm of said secondary unit with a bell crank flexure pivot means.
A method of making a force balance transmitter comprising the steps of forming a base means, securing a primary unit to said base means, securing a secondary unit to said base means, and operatively interconnecting a primary arm of said primary unit to a secondary arm of said secondary unit with a bell crank flexure pivot means.
