A catalyst is presented for use in the production of linear alkylbenzenes. In the method glass gobs are continuously separated from a glass melt flow continuously flowing out of a nozzle and the separated glass gobs are formed with glass forming members that are intermittently or continuously moving. A front portion contains capacitor assemblies, power DC Link, power electronic components, and a control panel. A rib is formed between these two trenches. The selector generates a processor clock from the standby clock during the frequency transition from the normal operation mode according to a selector control signal.
