1. They accomplish this secondly by inspecting guns to ensure safe mechanical operation . 2. Logic systems are used to sequence mechanical operations in many applications. 3. This is because of the increasing use of computerized devices to control mechanical operations . 4. The carrier blamed all but one on its mechanical operations . 5. Also, there is considerably reduced energy consumption for the mechanical operation of many NSP systems. 6. Although the Rhodes has the same mechanical operation as a piano, its sound is very different. 7. There is also a full basement with additional research facilities, and a penthouse for mechanical operations . 8. The condensed aerosol agent can be delivered by means of mechanical operation, electric operation, or combined electro-mechanical operation . 9. After 1900 factories were electrified, and electric motors and controls were used to perform more complicated mechanical operations . 10. The switching is done by applying a voltage to the material, or by performing some simple mechanical operation .
