| 11. | High-precision sextants have an invar ( a special low-expansion steel ) frame and arc.
|
| 12. | Invar and Elinvar are able to resist magnetic fields, allowing the watch to continue to keep accurate time.
|
| 13. | In those used in IMAX projectors, the electrode bodies are made from solid Invar and tipped with thoriated tungsten.
|
| 14. | A seismograph is also sensitive to changes in temperature so many instruments are constructed from low expansion materials such as nonmagnetic invar.
|
| 15. | The Type 99 can fire tandem shaped charged ATGMs similar to the Russian Invar with a range of up to 5 kilometres.
|
| 16. | For use as the compensation balance he developed a slight variation of the invar alloy which had a negative quadratic coefficient of expansion.
|
| 17. | The bimetallic temperature-compensated balance wheel was made obsolete by the discovery of low-thermal-coefficient alloys invar and elinvar.
|
| 18. | Scale materials include chrome on glass, metal ( stainless steel, gold plated steel, Invar ), ceramics ( Zerodur ) and plastics.
|
| 19. | Where can I find data on the thermal conductivity of Invar over a range of temperatures, say from 300 K to the melting point?
|
| 20. | A solid Invar balance with a spring of Elinvar was largely unaffected by temperature, so it replaced the difficult-to-adjust bimetallic balance.
