To perform a method for identifying color measuring strips having measuring areas on printed products, the color measuring strips are scanned with a color measuring instrument. The measured color values acquired by the color measuring instrument are stored in a computer and that the measured color values acquired are each assigned to a printing ink. A sequence formed in this way of printing inks is stored in the computer and then compared with color measuring strip types stored in the computer. The stored color measuring strip type having the greatest probability is then selected.

摘要:
An electric circuit operating on a single-phase power supply system for controlling the heat output of at least two heating resistances which are electrically connected in parallel and are installed in electric household appliances, particularly toasters, wherein the control is being effected in compliance with flicker standards and without feeding interference back into the power supply system. A switch is connected in series with each heating resistance, wherein the switches are activated by an electronic energizing arrangement. During a heating phase, the switches of the circuit are repetitively asymmetrically cycled in such a way that always only one switch is closed and all other switches are open, wherein the switch which is closed at a given time exclusively permits the through-passage of full waves from the power supply system.
