Abstract: 398,260. Rangefinders. VICKERSARMSTRONGS, Ltd. and WATSON, J. P., Vickers House, Broadway, Westminster. March 14, 1932, No. 7568. [Class 97 (i).] In an instrument for ascertaining the range of a rapidly moving object such as an aeroplane, means are provided whereby the measuring screw &c., the adjusted position of which determines the range, is placed under the control of a member moving in accordance with the ascertained change of range, as well as being under the control of the usual working head adjusted by the operator. In the form shown, a constant speed motor A operates a disc C driving a roller C<1> through balls mounted in a carrier C<2> displaceable across the disc by a knob D1, the distance of the carrier from the centre of the disc being adjusted so as to be proportional to the rate of change of range. The roller C<1> drives a shaft B operating one element of a differential E another element of which is rotated by the working head F. The third element of the differential receives the algebraic sum of these two rotations, and drives a shaft G having a cam-groove G<1> by which the deflecting prism H is displaced, the shape of the groove being such that when the shaft G is rotated proportionally to the range R, the displacement of the prism is proportional to 1/R. Alternatively, instead of the cam G<1> rotating with the shaft G, a helical screw may be used this screw being driven from the shaft by a conversion gear of such character that when the shaft rotates proportionally to R the screw rotates proportionately to 1/R. In Another form the member moving in accordance with the ascertained change of range is operated automatically for the changing range determined by a control apparatus the range-keeping element of which operates a transmitter controlling a motor which operates the said member. The control apparatus comprises a part operated by a motor in accordance with the displacement of a member of the range-finding device moving proportionately to the algebraic sum of the initial range and the change of range.
