published work has reflected a preponderant interest in plastics. Research 
has been performed on polydine-based synthetic binders for oil-free core 
reinforcements used in casting processes, polyamide resins as casting materi- 
als, and the use of nylon as a lining for metallic parts of sliding bearings 
and as components for food machinery. Interesting raw materials studied here 
are powdered wastes from feathers and down and from horn and hoof residues. 
Plastic articles have been produced by both injection molding and pressure 
casting. Of interest, also, is a process for drying varnish coatings on metal 
surfaces by infrared radiation. Thermodynamic and combustion properties of 
lignite fuels have been studied to exploit the region's peat deposits. Weld- 
ing, foundry, and metal-deposition processes have been investigated. A Trudy 
appears periodically.

Selected Staff Members: G. P. Klekovkin, Head of Laboratory for Build-Up 
Welding 
Description: 
The Institute was organized around 1960 and is primarily concerned 
with welding technology, particularly automatic processes. Recently, respon- 
sibility for standardization and normalization of machine construction was 
transferred to the Institute.
