An electron beam irradiation system for shooting an electron beam at a master disk to make recordings. The plant light ends, which are normally utilized as fuel gas streams are the primary feeds to the SMR Unit along with the tail gas purge from a gasification complex within the facility. The evaluation unit has three input terminals, and each of these input terminals is connected to one of the phase windings. Therefore, local-area wireless communication can be carried out between the air conditioner and the monitoring terminal, thereby making it possible to significantly save trouble for installation of monitoring instruments, such as cables and a converter, and to significantly curtail costs and manpower for monitoring work. In the case where the reference input signal has a 50% duty cycle, the output signals will also have a 50% duty cycle. The invention also relates to the use of these polyurethanes as thickeners or gelling agents in cosmetic compositions for topical application.
