Description

Rechenschieber, Maßstäbe und ähnliche Geräte. Rechenschieber bestehen gewöhnlich aus Holz. Rechenschieber aus Papier sind zwar auch bekannt, aber sie werden wegen ihrer geringen Genauigkeit und kurzen Lebensdauer nur wenig gebraucht.Slide rules, rules and similar devices. Slide rules exist usually made of wood. Paper slide rules are also known, but they are are rarely used because of their low accuracy and short service life.

Nur besondere Hölzer, wie z. B. Buchsbaum oder Mahagoni in ausgewählten Stücken sind für Rechenschieber gut geeignet. Diese Hölzer sind aber teuer, zumal in gegenwärtiger Zeit, da sie aus dem Ausland bezogen werden müssen.Only special woods such as B. boxwood or mahogany in selected Pieces are well suited for slide rules. These woods are expensive, especially since at the present time, as they have to be obtained from abroad.

Um diesen Nachteil zu vermeiden, soll nach vorliegender Erfindung ein mit synthetischem Harz (Kunstharz) getränkter Faserstoff zum Bau der Rechenschieber (und verwandter Geräte) verwendet werden. Im besonderen soll Papier verwendet werden, das mit dem »Bakelit« genannten Kunstharz getränkt ist, also Papier von der Art des als »Pertinax« bekannten, in der Elektrotechnik viel benutzten Isolierstoffes.In order to avoid this disadvantage, according to the present invention A fiber material soaked with synthetic resin (synthetic resin) for the construction of the slide rule (and related devices). In particular, paper should be used which is impregnated with the synthetic resin called "Bakelite", that is, paper of the type the insulating material known as »Pertinax«, which is widely used in electrical engineering.

Aus solchem Stoff kann sowohl der als :>Stab« bezeichnete Hauptteil des Gerätes mit den Führungen für den eigentlichen »Schieber«, wie auch dieser Schieber und sogar der »Läufer«, gegebenenfalls der die Glasscheibe haltende Läuferrahmen hergestellt werden. Stab und Schieber können je aus einem Stück gearbeitet sein oder, wie bei Herstellung aus Holz, aus mehreren miteinander vereinigten Schichten bestehen.The main part called "stick" can be made of such material of the device with the guides for the actual "slide" as well as this slide and even the "runner", possibly the runner frame holding the glass pane getting produced. The rod and slide can each be made from one piece or, as in the case of production from wood, from several layers united with one another exist.

Die Skalen können auf Zellhornauflagen des Pertinax oder auf dem Pertinax selbst angebracht werden. Im letzteren Falle muß man wegen der dunklen Farbe des Pertinax eine lichte Farbe für die Skalen verwenden.The scales can be placed on the cell horn pads of the Pertinax or on the Pertinax be attached by yourself. In the latter case, because of the dark color of the Pertinax use a light color for the scales.

Außer dem Vorzug, daß der hier vorgeschlagene Baustoff billig ist und im Inland selbst erzeugt wird, können noch als Vorteile geltend gemacht werden, daß der Stoff mechanisch fest, leicht zu bearbeiten, gegen Temperaturschwankungen und Feuchtigkeit unempfindlich, in allen Stücken also gerade für den vorliegenden Zweck besonders geeignet ist.Except for the advantage that the building material proposed here is cheap and is produced domestically, can still be claimed as advantages, that the material is mechanically strong, easy to work with, against temperature fluctuations and moisture insensitive, so in all pieces especially for the present one Purpose is particularly suitable.

Diese Vorzüge machen den mit Kunstharz getränkten Faserstoff auch geeignet für Geräte, die mit dem Rechenschiefer in gewisser Hinsicht verwandt sind, wie Maßstäbe, Reißschienen, Dreiecke (Winkel), Lineale, auch Kurvenlineale, Gradbögen (Transporteure) u. dgl. Aus Pertinax hergestellt sind solche Geräte den bekannten Ausführungen in Zelthorn oder Hartgummi erheblich überlegen.These advantages also make the fiber material soaked with synthetic resin suitable for devices that are related to the calculation slate in certain respects, such as rules, tear bars, triangles (angles), rulers, also curve rulers, degree arcs (Transporters) and the like. Manufactured from Pertinax, such devices are the known ones Considerably superior to designs in tent horn or hard rubber.
