We'll have them in three days, and it ought to be fairly simple to dope out the opposite of a tractor, too—a pusher or presser [sic] beam.

The careful positioning of the stations that held the warp of the collapsed fore element was lost as the tractor-pressor beam system took the unleashed overload current.

By the way they're braced, there are tractor beams and pressor beams and—there are vacuum tubes that have grids but apparently work with cold cathodes.

A pressor beam lashed out, an invisible hammerblow of repulsion, five times the strength of the enemy tractor.

My men say the pressor beam mounts were not designed to stand this sort of thing. Insufficiently braced. The hull plating has sprung in eight places.

Sections which should have fitted together very often had to be modified to make them join properly, and this necessitated moving the sections together and apart several times with massed tractor and pressor beams.

The rising crescendo of the pressor beam projectors began to vibrate the whole fabric of the ship.

A pressor beam speared out from the top of Matt’s helmet, pushing the alien against the back wall.

Lift towers locked down and threw up barrier panels of their own, and immensely powerful presser beams snarled to life. No one could have built an effective wall of pressers all around the resort, but the designers had stationed the generators at strategic points.

Sensors detected our hurtling bodies and a pressor field kicked in and caught us like a puffy pillow the size of an elephant. We landed gently and rolled to a halt. The pressor beams disengaged and we settled lightly on the floor.
