• The countertorque increases in proportion to the excursion of the coil from its zero position.

• Large departures of the equipotential surface from sphericity will not affect the result.

• When there is a departure of the controlled pressure from the set value, the out-of-balance force moves a multiplying valve.

• The constant reported in this work may have a deviation of 1.1% from the absolute valve.

• These errors account for the deviation of the measurements from theory.

• Variations from this composition are found in commercial steels.

• h is the variation of the strip thickness from the required value.

• It appears that building such a large device is feasible and would require no major departures from present practice.

• Always use the plotting board with North away from you.

• The concentration of a highly reactive intermediate has been followed from start to finish.
