Onward and upward flashed the gigantic duplex cone, its entire whirling mass laced and latticed together—into one mammoth unit by green tractor beams and red pressors.

‘Tractors and pressors as assigned—tip him over.’ The intensity of the bombardment did not slacken, but from the maulers to the north there reached out pressors, from those upon the south came tractors; each a beam of terrific power, each backed by all the mass and all the driving force of a veritable flying fortress.

A half-dozen rays, tractors and pressors both, stopped his protests, tore at him, pushed him, whirled him, until great foaming puffs of brilliance were erupted from his over-size body. In a fury, he lashed out with his own rays, but they were clumsily, ineffectively guided.

Place your arms through the stasis loops and your feet in the security platens. When you have done this the pressor fields will automatically be activated and you will be fully insulated against injury during the coming period of turbulence.

The two shuttles slowed and maneuvered from side to side; a little lower and they were positioned directly over the shaft. A lift pressor at the bottom of the shaft gently locked in and the two shuttles released their hold. A tricky operation.

Unless timing and power were precisely matched, a catastrophic misalignment of forces could occur.

A powerful pressor field kept out large predators and such insect life as was not necessary for the health of the plants inside.

We both began swimming for an hour or so every clear day, in the calm, pressor-guarded water off the beach.

The drivership lifted from Earth on pressor thrust.

Now formal sessions of both Senate and Praetorate were being held elsewhere while workmen labored among the ugly pillars and struts of emergency scaffolding inside the building; and outside, tractor beams and pressors were supplementing the normal stresses which had formerly held the dome unsupported over the chamber. The architects had planned superbly, but they had not anticipated that the Chamber would ever have a starship sitting on its roof.

Jadak’s improvisation had borne results Han was unprepared for. The faulty pressors and jets came back online with enough vigor to seesaw the Falcon’s starboard side down against the turbolift deck. The deck dropped, as well, so far and so forcefully that it tipped past level, nearly launching Jadak from the maintenance nacelle.
