This institute has developed instruments such as a radio inter- 
ferometer for measuring large lengths, a microcalorimeter for SHF power 
measurements, a prototype electromagnetic flow meter, a molecular frequency 
generator, an electromagnetic flow meter with square channel, device for 
measuring flame temperature, a spark chronoscope, an electronic optical 
pyrometer, a millivoltmeter, and an astronomic pendulum clock. The enthalpy 
and specific heats of silicon, beryllium, molybdenum, and boron oxide have 
been determined. The Institute also has studied the frequency deviation of 
frequency-modulated oscillations, the thermal-electromotive-force effects of 
temperature on telescopes, the instability of quartz-generator frequencies, 
the coupling of rectangular waveguides, measurement of tooth profile of reduc- 
tion gears and of elements of worm gears, the frequency of a maser (using a 
quartz standard), the movement of quartz clocks, and microwave power measure- 
ment with a microcalorimeter.
