Abstract: An impact activated automotive safety system relying upon relative movement between a drive unit and a chassis of an automobile and comprising a plurality of cables attached, at one of their ends, to the chassis on opposite sides, and slung around a rear portion, of the drive unit and respectively attached by their other ends to a plurality of safety features such as, for instance, a collapsible steering column, seatbelt coiling devices, and seat-lifting mechanisms, all of which would be activated substantially simultaneously in case of a frontal collision by forces transmitted to them by the cables.

Abstract: Method and apparatus for secondary cooling of a metal strand particularly of steel by the quantity-controlled spraying of a coolant in individual cooling areas by means of nozzles on areal portions of the strand surface, which as a consequence of the strand advance are intermittently cooled in the sprayed areal portions and reheated in the unsprayed portions by the continuing heat flow from the inside of the strand, whereby the coolant quantities which are fed to the nozzles of the individual cooling areas are controlled according to predetermined values. The coolant quantity per unit time Q.sub.t (l/min) fed to each nozzle proportionally to the strand advance speed is controlled according to predetermined values of the coolant quantity Q.sub.S (l/m.sup.2) which is fed to each strand surface unit by a nozzle. The coolant quantity Q.sub.
