Description

Have rulers with values for technical nuts and bolts proven * Such rulers are increasingly not only used in construction nails and on alternative objects, rather at assembly points for Großmaeohiae », BrUoken.» Ships and other large metal structures, This use during assembly Requires the smallest possible rulers with the largest possible indication of technical values. The solution this task is achieved through the use of a reflective baster ruler

As such, leohnik knows a number of gridded surfaces and of rasterized prints, di © when covering with a

reflective layer to reveal two images that are arbitrarily different from each other »τοη which one light on dark Ground and the other appears dark on a light ground · The new pattern does not look at itself in any way, such a baster reflex to evoke »rather, according to the utility model all optical means are used which produce such an Easter reflex. While so far this Basterreflect has mainly used for advertising purposes »according to the utility model it serves as a smock for a uniform» which Comparative values for technical screw types are displayed at as possible small dimensions with as much data as possible

Further valuable advantages of the new mneal are "that its printing for optical reasons under all circumstances" namely foolproof "only allows one single value group to be read." The other printed value group is then certainly invisible. It is known from such deflexed prints "that" one tries "to recognize both images" one recognizes none. This property of the Eeflexdruck has for the practical use "especially on construction sites the meaning" that any confusion of the numbers is definitely excluded * Έ ^ ηη one wishes to read, for example, the Jiaacimal load at the minimum yield point, which is summarized in a table "becomes the picture Every other fafel is erased "because only as a result of this erasure of every other imprint" the table about the maximum load becomes clearly legible.

Another use of the new ruler is that the

reflective ¹ BTUQk also clearly appears in dark areas. ! This effect can be increased close to the desire »if one uses the" well-known, self-reflecting biminescent colors. An increase in the practical value cannot be overlooked misplaced or lost have rappelled * i Röh be soharfes Eeflexleuchten deutlioh sa * Fk $ T8i $ & is if nvae its surface is exposed · 3> as new pattern is shown in the drawing in a beispieisweisen Ausftihrungsform.

fig «1 is the partial bottom picture of such an eeflex ruler» in a sehaabildliohem scheme.

fig, 2 is a plan of numbers on it.

Fig. 3 is an example of a second board »which can be attached to the ruler according to the utility model»

The ruler 1 is relief-like with an Easter 2 This toothed grid has two flanks 3 and 4 A 2-centimeter stick may be printed on the flanks 3 , as well as a table with depth values for Angiehdrehaoaent This tooth grid is shown as an example in fig * 2 shown · It may appear light on dark £ in the Eeflex. The other edges 4 of the gahnraeter may be printed according to ä & T Fig. 3 with a table for the maximum load at the minimum yield point.

lets »35 arrow XII in fig. 1 indicates the flashing » in which the falbeil "becomes visible near Fig. 3"

In all cases the brilliance of the lesson ensures a very detailed legibility of all numbers with very small ruler dimensions . The content of the print a mx ^ means for generating the double reflex can be chosen at will, as required by the conditions of use.
