Abstract: The invention relates to a method for shaping wire-shaped and rod-shaped starting materials by rolling, especially for rolling flat profiled elements consisting of a wire rod. The starting material is heated in a heating station at a desired temperature, shaped during at least one rolling process, and then cooled. According to the invention, once the starting material has been heated in the heating station, it is cooled in a cooling station to a pre-determinable rolling temperature; it is then shaped into a flat profiled element by rolling close to the gauge block, and then cooled and/or subjected to a subsequent treatment according to joining properties to be correspondingly adjusted. In this way, a series of different methods can be carried out by means of an installation for rolling starting materials with a patented structure, an austenite structure, a bainite structure or an undercooled austenite structure.

Abstract: The invention relates to a ski edge profile made from steel. To further improve the sliding properties compared to the ski edge profiles which are known from the prior art, according to the invention it is proposed for the ski edge profile to consist of a steel alloy with a relatively low thermal conductivity.

Abstract: A diagram analyzing device is provided which is particularly useful in simultaneous interpretation of a plurality curves representing economic data. The curves are drawn to a common scale and provided on transparent sheets so that they can be superimposed one on the other, two or more at a time. A transparent calculating ruler used in association with the curves enables a user to analyze the data presented in the curves, i.e., to make calculations using the data, and to determine the inter-relationships between different sets of data, as well to discern trends and rates of growth. A table of events used in conjunction with the curves enables the data to be interpreted in light of events taking place in the economic world which are thought to influence this data. The calculating ruler contains two different logarithmic scales along the longitudinal edges thereof, with the number "1" providing a baseline for each scale, together with a plurality of time scales across the width thereof.
