The aging and properties of greases have been studied, and ultra- 
sonic techniques were used to increase the thermal stability of 
commercial greases. Lithium greases were investigated for use in 
continuous manufacturing techniques. MoSo has been investigated as a high- 
temperature, high-vacuum grease. 
Relative to the use of sulfurous fuels and oils in diesel engines, 
the chlorine content of such fuels has been studied and investigations 
have been made of corrosive action in diesel engines, the mechanism of 
corrosion by additives in oil, and anticorrosion methods. The use of 
radioactive isotopes in the corrosion studies is being considered; other 
analytical tools utilized involve gas-chromatographic, polarographic, and 
mass=-spectra techniques. 
In the area of catalysis, studies have been made of the size and 
shape of catalyst particles in an effort to maximize production. Alumino- 
silicates have been studied relative to their catalytic properties and 
their use in silica gels. 
Fh 
A method has been developed for determining the effectiveness o 
an engine oil based on its filterability index, and the sensitivity of 
high-octane (over 100) fuels to detonation also is being investigated. 
An analog computer is available for use in handling problems 
of hydraulics associated with the development of large-scale underground 
petroleum resources. 
The Institute publishes a Trudy. 
The Institute maintains a branch at Leningrad, which studies similar 
problems of catalysts and also the synthesis of high polymers. The Deputy 
Director of the Leningrad Branch in 1958 was A. Vvedenskiy.
