A machine for processing printing material includes the backing plate formed of aluminum sheet metal. A method for punching and scoring a printing material includes forming a punching and scoring backing plate of aluminum sheet metal, and punching and scoring the printing material with the backing plate.

Abstract: A method and an apparatus is provided for the determination of the content of organic carbon (TOC) of liquids, in particular ultra-pure water, wherein a liquid sample under investigation is located in a reaction chamber and carbon present in the liquid is statically oxidized to mainly carbon dioxide. After oxidation of the carbon, the sample quantity is transferred to a measuring cell, connected to the reaction chamber by liquid entering the reaction chamber from the outside the reaction chamber, where (i.e. in the measuring cell) the carbon concentration of the sample, which is proportional to the carbon content, is dynamically registered as the sample flows through the measuring cell.

Abstract: A cylindrically shaped coil of resistance wire constitutes a source of infrared radiation which is located within a reflector comprised of a curved reflector section having a reflecting surface shaped to resemble an axially bisected rotationally symmetrical paraboloid, and a cylindrical reflector section which extends from an open side of the curved reflector section. The focal points of the reflecting surface are located on a circle which coincides with the outer circumference of the cylindrically shaped coil.
