Abstract: The invention refers to a process of treatment and environment-friendly utilization of asbestos-cement products including a thermal process to transform the asbestos component. Inventively, this is achieved by a coarse reduction of the asbestos-cement products under black side conditions with maintained vacuum. Then, the material is ground to asbestos-cement meal and fed to the flame zone of the rotary kiln of a cement clinker production line. Depending on the fuel type used, the portion of fed asbestos-cement meal varies between 2 and 5%, related to the amount of cement raw meal, substituting 2 to 5% of the cement raw meal mix at a time. The thermal transformation of the asbestos component takes place with temperatures of approximately 1800.degree. C. in the burner zone. The modified residual substance becomes a constituent of the cement clinker due to assimilation in the kiln charge.

Abstract translation: 本发明涉及石棉 - 水泥制品的处理和环境友好利用的方法，包括转化石棉成分的热处理。 本发明的这是通过在黑色条件下在保持真空的情况下大大减少石棉 - 水泥制品而实现的。 然后将该材料研磨成石棉 - 水泥粉，并送入水泥熟料生产线回转窑的火焰区。 根据所使用的燃料类型，进料石棉 - 水泥粉的部分与水泥生料的量相关，为2至5％，代替水泥生料混合物的2至5％。 在燃烧器区域中，石棉组分的热转化发生在约1800℃的温度下。 由于窑炉装料中的同化，修饰后的残留物质成为水泥熟料的成分。

Abstract: AN APPARATUS FOR MEASURING TEMPERATURES IN PREFERABLY HIGHLY VISCOUS MEDIA, SUCH AS IN A THERMOLPLASTIC SYNTHETIC MELT. THE TEMPERATURE MEASURING APPARATUS DETERMINES A RADIAL TEMPERATURE PROFILE OF A FLUID FLOWING THROUGH A CONDUIT USING ONLY ONE MEASURING POINT, BY AXIAL ADJUSTMENT OF A TEMPERATURE SENSOR. ADVANTAGEOUSLY, A THERMOCOUPLE OR A SEMICONDUCTOR RESISTANCE THERMOMETER CAN BE USED AS THE TEMPERATURE MEASURING DEVICE.

Abstract: A process for extruding a film having small variations in thickness by regulating the quantities fed to a worm press and by regulating the extrusion process. Marginal strips and waste products of extruded film are re-processed by returning these materials, slicing them and directly weighing them before being fed to the filling bin of the screw press. In order to regulate the quantities fed to the screw press, the weighed material per unit of time is continually subtracted from a nominal value set by a volume regulator associated with the raw material seeder devices. The filling degree of the screw press is measured as the mass pressure between the screw press and a constant volume pump such that the filling degree is maintained constant during the extrusion process.
