Abstract
421,315. Direction-finding apparatus. AKT.-GES. C. P. GOERZ OPTISCHE ANSTALT, Pressburg, Bratislava, Czecho-Slovakia, and PETSCHENIG, K., 5, Sonnleithnergasse, Vienna. April 20, 1934, No. 11992. [Class 97 (i)] Apparatus for determining the direction of a target measured from an observation station and converting it into the direction measured from a distant working station such as a gun position, comprises at the observation station a gimbal mounted telescope for measuring the angular elevation of the target in two planes at right-angles to each other, these angles being transmitted to the working station and there corrected for the difference between the coordinates of the two stations by means of a linkage adjusted in accordance with these coordinate differences and with the ascertained altitude of the target. The observation apparatus comprises a pair of telescopes 12, 13, Fig. 4, having parallel axes and rotatable about a common axis 6. The telescopes are connected by cranks 7 and a rod 8 to which is secured an arm 9 having an extension 9<a> parallel to the axes of the telescopes. The extension 9<a> passes through slots in circular members 3, 4 which are rotatably mounted about axes 2<a>, 2<b>, at right angles to each other, in a bearing member 2 rotatable in azimuth about a pivot 1<b>. The members 3, 4 thus receive rotations equal to the projections alpha, #, on planes at right angles to each other, of the angular elevation of the target, these angles being conveyed to the working station by transmitters 10, 11, and read on indicators Ealpha E#, Fig. 3. The apparatus at the working station comprises two telescopes F<1>, F<2>, Fig. 3, having parallel axes and mounted on gimbals K, K<1> and C, C<1>. A threaded spindle S<1> extending at right-angles to the axis K<1> carries a non-rotatable nut Y<1> which can be traversed along the spindle by a handle H. A threaded spindle V<1> mounted in the nut Y<1> carries a nut Z<1>1 which can be adjusted along the spindle so that its distance z<1> from the nut Y' represents the ascertained altitude of the target. The nut Z<1>1 carries a pin engaging a lever h<1>1 rotatable with the telescope F<1> about the axis K<1>. Also extending from the nut Z <1>1 is a threaded spindle s<1> carrying a nut Z<1>, the distance #<x> of which from the nut Z<1>1 is adjusted to represent the difference between the abscissµ of the two stations, the nut Z<1> being connected to a rod h<1> secured to a shaft X<1>, which is parallel to the axis K<1> and is displaced vertically therefrom by a distance #<z> representing the difference between the heights of the two stations. In operation the wheel H is turned so that an indicator on the shaft X<1> is in alignment with the indicator Ealpha. The rod h<1> is then inclined at the angle alpha to the horizontal and the telescope F<1> is turned about its axis K<1> through the corresponding angle alpha<1>. A similar arrangement is provided for rotating the telescope F<2> about its axis C<1> through the angle #<1>. The axes K<1>, C and K, C are geared together so as to rotate in unison, so that both telescopes receive the resultant of the two component elevations alpha<1>, #<1> and are therefore maintained on the target. The spindles S<1>, S<2> are provided with extensions S<1>1, S<1>2 carrying markers M', M<2> co-operating with uniformly-rotated drums T<1>, T<2> to produce records from which the component velocities of the target in directions at right-angles to each other can be determined.
