Blackstone-Ney Ultrasonics

the name blackstone has been associated with cleaning since the year 1857 when william a. blackstone built the first mechanized, hand-powered clothes washing device consisting of a wooden tub with a washboard interior and a milking stool agitator. in 1958, the blackstone corporation purchased murdock laboratories, a small company researching ultrasonic cleaning, and attempted to use ultrasonic technology to enhance the already high quality blackstone line of home and commercial laundry equipment. although ultrasonic technology did not revolutionize the laundry industry, blackstone continued development of ultrasonic equipment and techniques for use in industrial, medical and other applications. blackstone’s credits include the development and patenting of the first rugged, highly efficient piezoelectric transducers; ultrasonic devices for use in urology and cardiology; the first large scale ultrasonic solder pot; and auto-tuned, solid state ultrasonic generators. blackstone ultrasonic
