Description

In the main patent 1218 186 is a method for encryption and storage of topological representable structures, in particular of chemical structural formulas, circuit diagrams and schemes for documentation and research using data processing systems, in which the individual points (building blocks) of the structure picture at least with regard to their connection to other points of the same image as well as the peculiarities of this binding through identifying data in memories recorded and for this on a rasterized sheet as mechanical, optical, magnetic and / or electrical evaluable linear markings are transmitted, which then by relative movements of the as far as prepared rasterized sheet opposite tactile organs, which correspond to the markings are sensitive, converted into preferably electrical impulses, the structural image to be encrypted from exclusively horizontal, vertical or diagonally marked connections of the Grid points is deposited on the sheet and aligned progressive oscillating relative movements the tactile organs are queried against the sheet.

According to the additional patent 1 276 378 that is with the

ίο grid and the one to be scanned in it Structural image covered sheet additionally with one or more marked clock tracks known per se Art prepared for synchronization by coordinate area, the marks of which correspond to the oscillating form of movement of the sheet opposite the tactile organs are arranged and through their marked extension determine the gate times for the tactile organs querying the structure image. as Memory for the converted impulses are perforated

ao cards and one or more card punchers used as pulse conversion means, their timing by the tactile organs moving over the thus marked clock tracks of the sheet. The latter patent also teaches

»5 two swinging movements of the prepared one Of the sheet opposite the tactile organs, which are out of phase with each other (see Fig. 1).

Two factors have a great influence on the manual workload of the encryption process. The scanning takes place safely and correctly when the structure to be scanned exactly on the grid sheet is drawn, d. H. the marked horizontal, vertical and diagonal lines from point to point Point are not crooked. Furthermore, the sheet must be precisely adjusted and placed in the scanning device. the possible errors in these two operations add up. The level of care that goes into doing this has to be determined the speed of operation of the coding. By the invention Design of the clock track attached to the edge of the sheet, the permissible tolerances are essential elevated.

The use of clock tracks in any type of scanning process is known. You always own a finite width and its surface elements, or the gaps between the elements, are parallel or aligned perpendicular to the general direction of movement. Even when vibrations are superimposed So far, the general scanning movement has the vertical and parallel alignment of the Retain clock track fields (see FIGS. 1 and 2) because the straight line for the time rhythm of the scanning Basic speed decisive and the superimposed oscillation on this rhythm without Influence is.

A necessary increase in the tolerances was previously in certain of the required gap certain limits by enlarging

öo of the areas of the clock track fields.

It has now been found that the tolerances for the position of the marked lines and for the insertion of the grid sheet in the encryption device can be significantly increased, if according to the invention; äß the individual areas and gaps of the clock track fields compared to the general Direction of movement obliquely extending lines are limited.
