Re chenschieberSlide rule
Gegenstand des vorliegenden fflusterschutzes ist ein Rechenschieber·The subject of the present fflusterschutz is a Slide rule
Dieser besteht, gemäss der anliegenden schaubildlichen Darstellung aus einem Stab dessen Querschnitt das Profil eines rechteckigen Trapezes aufweist, mit einer längs der geneigten Seite geführten schwalbenschwanzformigen Nut, in welcher eine verschiebbare Zunge gleitet die eine in Flucht mit der oberen kleineren Seite des Stabes liegende Seite aufweist, wobei auf diesen beiden Seiten in entgegengesetzter Richtung verlaufende lQgarithmische Skalen aufgezeichnet sind wahrend die spitz auslaufende Kante des Stabes als Masstab ausgebildet ist*This exists according to the attached diagram Representation of a rod whose cross section has the profile of a rectangular trapezoid, with one along the inclined side guided dovetail groove, in which one sliding tongue slides one in flight side lying with the upper smaller side of the stick with IQgarithmic scales running in opposite directions recorded on these two sides are while the tapering edge of the rod as Scale is formed *
Die Zeichnung lasst zudem erkennen* wie man mit Vorzug die Zunge mit einer Riffelung versieht, die die Handhabung des Rechenschiebers erheblich erleichtert.·The drawing also shows * how to do it with preference the tongue is provided with a corrugation that makes it easy to handle the slide rule is made much easier.
Der Rechenschieber kann aus beliebigem Material herge-The slide rule can be made of any material
stellt sein, vorzugsweise jedoch aus einem gepressten Kunststoff· be made, but preferably made of a molded plastic
Mit diesem Rechenschieber findet die Multiplikation nach Art einer üblichen Division statt. So z.B. steht gemäss der Abbildung die Zahl $0 der Zunge gegenüber 26 des Stabes, was am hinteren Ende der Zunge das Resultat $0x26 « 13OO auf dem Stab ergibt, wahrend umgekehrt 1300*50 wie eine Multiplikation gesetzt auf dem Stab das Resultat 26 ergibt.With this slide rule, the multiplication takes place in the manner of a usual division. For example, according to the figure, the number $ 0 of the tongue is opposite 26 of the stick, which at the rear end of the tongue gives the result $ 0x26 «13OO on the stick, while conversely 1300 * 50, like a multiplication set on the stick, gives the result 26.
Bin derartiger Rechenschieber eignet sich besonders für junge Schüler, als üebungs- und Rechnengerät bevor sie zu den grossen Schiebern greifen, z.B. gemass der Patentanmeldung ρ 4005 IXb/42 mB derselben Anmelderin.Such a slide rule is particularly suitable for young students, as a practice and arithmetic device before they go to grab the large slide, e.g. according to the patent application ρ 4005 IXb / 42 mB by the same applicant.
