Patentansprüche:Patent claims: i. Waagebalken, dadurch gekennzeichnet, daß er aus Metall gepreßt ist oder aus einer kera-' Fig. 2 ein Schnitt nach Linie./-./ in Fig. 1.i. Balance beam, characterized in that it is pressed from metal or from a kera- 'Fig. 2 a section along the line./-./ in Fig. 1. Der in der Zeichnung dargestellte Waagebalken ist aus Metall oder einer keramischen Masse gepreßt. Im letzteren Falle muß der den Balken bildende Preßkörper natürlich noch gebrannt werden. Als besonders geeignete keramische Masse kommt Hartporzellan o. dgl. in Betracht.The balance beam shown in the drawing is pressed from metal or a ceramic mass. In the latter case, the pressed body forming the beam must of course still be fired. A particularly suitable ceramic mass is hard porcelain or the like. Zur Erzielung eines günstigen Trägheitsmomentes des Balkens ist dieser gemäß der Zeichnung vollwandträgerartig mit Versteifungsrippen 1 ausgebildet. Diese Form des Balkens läßt sich auch aus Metall gut pressen. Ein derartiger aus Metall gepreßter Balken hat neben der geringen Zerspannungsarbeit bei der Herstellung den Vorzug, daß er immer gleichmäßig verdichtetes Material besitzt. Durch dieses Verdichten wird die Elastizität herabgesetzt, so daß auf diese Weise hergestellte Waagebalken aus Metall sich weniger durchbiegen.To achieve a favorable moment of inertia for the beam, this is as shown in the drawing Solid wall girder-like with stiffening ribs 1. This shape of the beam can also be pressed easily from metal. One made of metal In addition to the low machining work during manufacture, pressed beams have the advantage that he always has evenly compacted material. This compression reduces the elasticity, so that metal balance beams made in this way sag less. Der Vorteil von Waagebalken aus keramischen 65 _ Massen liegt darin, daß diese Balken nicht nur praktisch keine Elastizität zeigen, sondern auch eine kleine Wärmedehnungszahl haben. Letzterer Vorteil wird übrigens wenigstens teilweise auch dann erreicht, wenn der Balken aus der keramischen Masse auf andere Weise als durch Pressen hergestellt ist.The advantage of balance beams made of ceramic 65 _ masses is that these beams are not only show practically no elasticity, but also have a small coefficient of thermal expansion. The latter Incidentally, the advantage is at least partially achieved if the beam is made of ceramic Mass is produced in a way other than pressing. Vergleicht man in nachstehender Tabelle Aluminium und eine keramische Masse, wie Hartporzellan o. dgl., so sieht man, daß die Wärmedehnungszahl der keramischen Masse bei demselben Raumgewicht wie Aluminium sehr gering ist.If one compares aluminum and a ceramic mass such as hard porcelain in the table below o. The like. So you can see that the coefficient of thermal expansion of the ceramic mass with the same density how aluminum is very low.
