    • A 2-roll piercing mill for producing hollow blocks from a rolled material comprising high alloy steels has guide tools for the rolled material. The guide tools are arranged for closing a reforming zone of the piercing mill transversely with respect to the rolling axis as the hollow block is pierced. In this arrangement, each of the guide tools includes a base body made of a carrier material and a working face made of a material that has antiadhesive properties with respect to high alloy steels and high hot strength. Prior to the piercing operation, the temperature of either the working face or the entire guide tool is raised above room temperature to avoid high thermal stresses.
    • 用于由包括高合金钢的轧制材料生产空心块的双辊穿孔机具有用于轧制材料的引导工具。 引导工具布置成当中空块被刺穿时相对于滚动轴线横向地关闭穿孔机的重整区域。 在这种布置中,每个导向工具包括由载体材料制成的基体和由相对于高合金钢具有高的耐粘附性和高热强度的材料制成的工作面。 在穿孔操作之前,工作面或整个引导工具的温度升高到室温以上,以避免高的热应力。

    • In a demodulator for radio data signals the transmission of which is made by phase-keying of a suppressed subcarrier the occurence of transient times is avoided in that the received signal of subcarrier frequency is transformed into a first square wave signal (A) and that a second square wave signal of subcarrier of frequency is formed which is brought into such a time relationship to the first square wave signal that by means of a comparison of both square wave signals a phase information for the first square wave signal (A) is obtained. Demodulator can be implemented by means of only digital components.
