11. Steam acts upon these blades, producing rotary motion . 12. The rotary motion as well as the laying movement is achieved by using computer controlled motors. 13. The unconventional rotary motion steam-cylinder engine and pump were Holly's invention ( US39259A and US12350A ). 14. The "'Geneva drive "'is a gear mechanism that translates a continuous rotation into an intermittent rotary motion . 15. These beat in a rotary motion , pulling the food forward in a steady stream from the mouth. 16. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion . 17. Where the motor is adapted to produce rotary motion , the return mechanism consists of a crankshaft and flywheel. 18. Wobbler technology uses an off-center rotary motion and groove configurations on the sprinkler deflector pad to increase uniformity. 19. For mechanical power to be applied to a stocking frame, it had to be adapted for rotary motion . 20. This device operates with a staged rotary action such that the actual cutting is part of the rotary motion .
