Stanford, Conn. Ultrasonic- sound waves pitched so high they cannot be heard are now being used for what is believed to be the first time in industrial cleaning on a production line basis. A ultra sonic cleaning machine, developed by engineers of the General Electric Company's General Engineering Laboratory, Schenectady NY, directs sound waves through a cleaning solvent to remove oil, grease, lapping compound, and metal particles from tiny openings and corners of electric shaver heads. Officials of Schick Incorporated, manufactures of electric shavers here, report that the new machine does a more thorough cleaning than any method yet devised. Action of the sound wave is said to increase greatly the effects of the cleaning solvent, resulting in greater penetration into corners and crevices where cleaning solvent alone would be ineffective. George Kalenich, Schick maintenance superintendent has removed front of the machine to watch shaver heads get their Ultrasonic Bath
