in the case of a previously unassigned start time is over device, it is not necessary to make any statement about the adaptation to the short term. Here lies the pre-measuring problem necessary to receive one impulse or several part of the recognition of several movement or movement impulses at previously determined times from the z-change positions on a screen, just as the gauges themselves do. The solution of this device according to the invention makes it possible. If the 5 chen task is carried out according to the invention by eieicin-start at an assigned time, for example in the case of dei see contactors, the pointer position "zero" of the timer controlled by the switching disk, so will be that which together with the clock hands ^{a ^^ l} ~ time acquisition an intermediate position possible. run around the knife. Contact-free, more precise If the start takes place at some point while the time measurement is running, this has proven to be the case.

This means that both the time of the start-up and the time of the position of the target appear on the picture when it is made recognizable by a flash of lightning near the kagangs. This is the only way in which there is lighting in mera and gray-tinted and given such a situation a statement from an image, if with structures, if the flash is possible for exposure. The advantage mentioned cannot only be obtained from a different direction. Using corresponding target photography, but with many photographic adaptations through different looks, use time measurement projects to locate the flashes of light to expose one of them it will be solved. It is first necessary by the selection according to the invention that with successive erder the suitable rotation speed of the clock hands 20 following flash exposures of the same image from the arrangement of the respective Kurzzeitmeß-Problem- different directions on the image to adapt the pointer position. As with every photographic, as a result of the different exposure moments or cinematographic recording, the conditions appear several times, but due to the correct setting in terms of the scope of the correct distinctive white and gray tones, the illumination, the sharpness of movement and the depth of the a _{5 can} be assigned to the moments that solve the problem So -will meet the sharpness. Each image is exposed twice behind the determination of the time between the flashes of light by means of brief flashes of light. As I. . the pointer appears in two positions on each image. With the device according to the invention, a different arrangement is required. The same pointer appears on the picture in the 30 bar. The clock hands of the meter eater are white and one position is white and in the other one is running on a black background. The gray tone, which is clearly distinguishable from each other, in the given photographic recording is done with additional visible structures, or several different colored flashes of light appear one after the other in the pointer positions on the image at predetermined moments. The locations of the JJUU-different colors. 35 devices have no influence on this: the process. Basically, it is possible to use the timepiece with color-sensitive recording material, only one clock hand and one dial, and get it in the evaluation of the images of the recording. However, it is more universally applicable to arrange the clock hands of the timepiece multiple times, with several clock hands and dials in one picture, but in different colors and one next to the other. Large areas of the short-term measurement 40 possible so the determination of the time between the can be recorded with such a timepiece, flashes of light.

in which a clock hand in V.00 seconds, in V »The advantage achieved with the invention consists of seconds, rotates in 1 second and in 10 seconds. speaking of the task on the one hand then that With a 10-part division of the dial, with the aid of the front notation according to the invention so short-term measurement results from '/ iod · seconds to 45 simple photographic and cinematographic 10 seconds can be used correctly on the pictures or FiI recording devices without them evaluate the men and are documented. Device for short-term measurements only with special continuation it is possible for the timers to give evaluable results with the slopes. Farther The device according to the invention can be combined with high-speed photography; with benieren and there improved evaluation and documentation devices and methods of short-term mentation options that are already known to accomplish. Measurement and high-speed photography are suitable for this especially the arrangement of a clock hand on the kidneys and simplifies the evaluation of the brdem there Timepiece that runs in Vim · seconds. results. In addition, the timepiece also turns on the combination with the normal time clock is possible with the help of an electric synchronous motor, in order to realize long-lasting processes with a total of 55 drives in a particularly economical way praise times to capture. lets the use of other more precise running

Other possible uses of the invented drives, such as electronically controlled motors as according to the device are that the Zeitmesserantneb is possible. Clock hands of the timepiece other time units than in the drawings are exemplary embodiments

Use of the device for short-term pulses generated and photographed in a known time sequence, measuring arrangement according to patent claims 1, 2 and 3, the light pulse source is directly connected to the bewed thereby marked that connected at any genden object. By this condition Position of the timer the change in position (object with light pulse source) becomes a general one of the object to be moved (1 «i) is very difficult to apply this arrangement. Bedem Contact associated with a timer, on the other hand, uses flashes of light in a known time sequence (10-11-12) is introduced (A b b. 3). for exposure of the object in photography, so received photographic recordings like those from medical or sporting movement studies 45 are known. The evaluation of such recordings Time-related values are often very difficult or impossible. The invention relates to a device for short The invention is based on the object by means of Timing arrangements in which at least two movements of a device short-term measurements without large movement positions one after the other together with a 50 workload in evaluating the measurement result timers be photographed. Da- da in the pictures and without the involvement of Wirtbei one can use elaborate photographic or childlike complexes on every image created in this way to enable two positions of the change to be measured by special matographic devices, or movement in the respective time allocation. Furthermore, this device should be used in combination recognize. The use of the 55 according to the invention with already known methods of the short-term measuring device is said to be the solution and high-speed photography there compared to known processes Ease the evaluation of the measurement results and also facilitate the evaluation of the measurement results Use of simple photographic and children. nematographic devices allow that without It is a major advantage to have two on one picture this device for short-term measurements not to 60 or more positions in the respective temporal would use. The photography has srh. to be able to recognize in the assignment. This should be done on the case of documentation of time determinations have been explained since the game of target photography. In the matter of proven. The photograph of a stopwatch as a known simple form is usually the Timepiece together with a moving start, the pointer position "zero" of the timepiece to the object is known (example: FUm photo of a 65 ordered. The image of the target photograph shows the mofall end Water droplets together with a stoppage of the finish line and that from the start on). The timepiece to be photographed can use the elapsed time. It is not possible to have a predetermined one also recognizable with several intermediate Zif positions arranged next to each other on this picture, and
