31. To prevent this, scramjet engines tend to have an isolator section ( see image ) immediately ahead of the combustion zone. 32. Openings are engineered ( i . e ., using continuous overpressure ) to exclude external contamination from entering the isolator chamber. 33. A rear-mounted Boeing 707 spike-styled HF antenna isolator , and antenna were also added to the tail section. 34. On April 7, 2009, the band's second album, " Oscillation Isolator " was released independently. 35. On the isolator structures the various concrete members are bolted together using high tensile steel bolts to a pre-determined torque. 36. Because the power is absorbed in an external load, cooling is less of a problem than with a resonance absorption isolator . 37. This bearing support may be adapted, with certain precautions, as a seismic isolator to skyscrapers and buildings on soft ground. 38. The isolator provides a low insertion loss from the SLED to the fiber and a high insertion loss in the back direction. 39. The use of rubber isolator engine mounts was introduced in 1973 to help reduce vibration from the one lung Kohler K engines. 40. This metallic bearing support may be adapted, with certain precautions, as a seismic isolator to skyscrapers and buildings on soft ground.
