Automation has developed digital program-control devices for the electro- 
spark equipment. Electrospark methods have been introduced in various 
industries. They have been used to harden forging dies, locomotive wheels, 
and rock drills, recondition bearings, grind flour-mill rolls, polish 
electronic vacuum instruments, and machine precision tools and complicated 
parts. 
The Laboratory has investigated power-source problems in welding 
and has designed and built a series of welding rectifiers. 
Some limited research in chemistry is also being conducted at the 
Laboratory, including the construction of an experimental installation for 
the production of acetylene by the action of an electric discharge on 
liquid petroleum products. 
The laboratory periodically publishes a Trudy.
