Instrument for measuring acceleration, gradients, and other physical aspects of a potentially moving vessel, using two magnetic discs on a spring, within an encompassing magnetic field. Patent text includes equations. If the accelerometer registers n feet per section when going uphill and the speed remains constant, then the gradient will be sin(-n/g) or approximately 1 in g/n. (Not sure what that means exactly; the units of g are acceleration units, so the sine is apparently to be taken of a quantity with units.
