Description

Uzywane dotychczas suwaki rachunkowe ma¬ ja te wade, ze przesuwna linijka, sluzaca do otrzymywania wyników' dzialan matematycz¬ nych, wskutek czestego i dlugotrwalego uzywa¬ nia wyciera sie. Pociaga to za soba czesto' bar¬ dzo niedokladne wyniki rachunkowe.Tej wady nie posiada suwak rachunkowy, be¬ dacy przedmiotem wynalazku.Suwak ten uwidoczniony na rysunku sklada sie z czesci 1 i 2, zaopatrzonych^ w wyzlobienia, w które wsuwa sie listewke A,, laczaca wspom¬ niane dwie czesci. Oprócz tego czesci 1 i 2 sa polaczone srubami 5. W razie wytarcia sie prze¬ suwnej linijki 3 mozna w kazdej chwili zblizyc do siebie czesci 1 i 2 przez przykrecenie srub 5 tak, aby linijka 3 poruszala sie bez luzu. PL PLThe slide rules used to date have the disadvantage that the sliding ruler used to obtain the results of mathematical operations wears out due to frequent and prolonged use. This often results in very inaccurate calculation results. The slide rule, which is the subject of the invention, does not have this disadvantage. The slide rule shown in the drawing consists of parts 1 and 2, each provided with grooves into which a strip A, connecting the two parts, is inserted. In addition, parts 1 and 2 are connected by screws 5. If the sliding ruler 3 becomes worn, parts 1 and 2 can be brought closer together at any time by tightening the screws 5 so that the ruler 3 moves without play.
