Abstract: 751,874. Targets. FLORY, L. J. T. Feb. 10, 1954 (Feb. 23, 1953], No. 3905/54. Class 20(1). A movable target comprises two guides 2, e.g. cables, inclined to the ground, a movable unit 6 supporting a target 7 and mounted athwart the cables 2, a first cable actuated by a motor to move the unit 6 along the cables 2, the target 7 being movable transversely of the cables 2 along the unit 6, by a second cable 23 actuated by a motor 21, and means on the unit 6 for reversing the direction of the target 7. The cables 2 are parallel and are each tensioned between the ground and the top of a post, pulleys 12 allowing side parts 11 of the unit 6 to move on the cables 2. Each part 11 includes a spring-pressed arm 14 pivotable at 15 to tilt a mercury switch 25 or 26 when the target 7 approaches one or other end of steel wires 17, 18 which interconnect the parts 11 and complete the unit 6. One part 11 has a reversible electric motor 21 which drives the cable 23 to move the target 7, the direction of the motor 21 being controlled by the switches 25, 26. In addition to actuation of the switches 25, 26 by the approach of the target 7, the following circuit controls the direction of the motor 21 to ensure an erratic course for the target 7. A motor 48 drives a wheel 46 having teeth of three different radii. The teeth engage an arm 62 and according to the height of the tooth, so is the arm 62 tilted to move a mercury switch 34 right or left or maintain it in the neutral position shown. When neutral, the motor 21 is not energised, contacts 33, 51 not being interconnected, and the target 7 has no transverse motion, moving only with the unit 6 along the cables 2. When tilted, e.g. to the right in Fig. 3, the switch 34 closes a circuit to energise in this case the right hand side of the motor 21, the circuit being from battery 36, contacts 51, 41, lead 40, contacts 39, 42, lead 43 and motor 21 to earth. The target, which starts from ground level, is shielded from the marksman initially, and the circuits for the motors 21, 48 are closed before that of the motor responsible for moving the unit 6, whereby the target 7 is given a transverse movement before appearing above the shield. Specification 690,154 is referred to.

Title: Improvements in or relating to optical instruments for measuring distances
IPC: G01C3/12
Filed: 1926-02-15
Abstract: 247,606. Elek, S. Feb. 14, 1925, [Convention date]. Tacheometers.-In order to utilize the telescope of a surveying instrument for distance measuring, two prisms lenses or mirrors are arranged in front of the eye-piece and at an angle to one another so as to divide the field of vision into right and left hand portions, having optical axes with a given difference of level. By this means the distance of the stadia rod from the instrument can be read directly by observing the apparent position of the vernier in one half of the field with reference to the zero position of stadia rod in the other half of the field. In the example utilizing reflecting prisms a, b the rays o from the object glass are reflected from the relatively inclined surfaces, T1, T2, t1, t2 so that they emerge from the two prisms with a difference of level amounting, e.g. to one-hundredth of the focal length of the objective g. In this case, the distance is one hundred times the apparent difference of position of the vernier and zero of the rod. An initial adjustment of the vernier enables the distance to be calculated to the centre of the observing instrument. In other examples, refracting prisms and portions of concave lenses are used to produce the same result.
