1.   Knocked from its invisible supporting cradle of needle-thin tractor beams, the effigy swayed.

2.   And NASA is building an antimatter engine and tinkering with a tractor beam.

3.   I spend one night with a person, the tractor beam locks in, this is my mate for life.

4.   Some ships need to be disabled, others locked with a tractor beam and others destroyed.

5.   You could almost feel him activating the corporate tractor beam at the Microsoft Death Star in Redmond, Wash.
