Abstract
783,104. Electric measuring systems. MINISTER OF SUPPLY. Jan. 12, 1956 [Jan. 13, 1955], No. 1065/55. Class 40 (1). A linear accelerometer of the kind in which a mass 11 is constrained to move in an arcuate path when subjected to acceleration in the active direction, i.e. the direction tangential to the arc when the mass is in its zero position has in addition to the compliance in the active direction, elastic compliance substantially in the direction of the cross acceleration, whereby the path of the effective centre of mass under the influence of acceleration in the active direction is changed and errors are reduced. In the construction shown, the mass 11 is an arm which is mounted by means of a spring pivot 12 comprising four crossed leaf-springs. The arm carries the moving elements of a direct current operated force motor 13 and of an alternating current operated pick-off 14, these operate in conjunction with amplifier means, not shown, whereby there is imparted to the arm 11 by the motor 13 a restraining force proportional to the deflection of the arm 11 about its pivot under the influence of acceleration. To provide the elastic compliance substantially in the direction of the cross acceleration two equal masses 15 are secured to the ends of a single flat spring leaf 16 which is secured mid-way of its length to the free end of the arm 11. The effective mass of the accelerometer is arranged to have the same effective elastic compliance in the direction of the length of the arm 11 when in its zero position as it has in the direction in which the leaf-spring 16 extends when the arm 11 is in its zero position.
