Abstract: A payload is housed in a deliverable body of a device, such as in a projectile, and this device is delivered as close as possible to a target. At the landing point, a drive system of the body is activated to take the payload directly to the target. The target is described by target coordinates, for example, which are programmed into the device before it is launched. The device itself can be steered or unsteered. The drive system installed on the body or formed by the body is variable and should occupy a minimum of space.

Abstract: A method of rolling rod-shaped rolling stock, particularly rod steel or wire, in a roll stand having two work rolls which are adjustable relative to each other in an adjusting direction and which together form a roll groove with an actual roll gap, so that the rolling stock exits the roll stand with an actual height and an actual width at a rolling speed, wherein the rolling stock is rolled with an actual rolling force. The method includes the steps of adjusting the work rolls through a hydraulic cylinder unit; measuring the actual rolling force; measuring with the aid of the actual rolling force a roll gap spring-back resulting from the rolling force; determining with the aid of the roll gap spring-back and a desired roll gap a roll adjustment correction value such that the actual roll gap approaches the desired roll gap; and changing a roll adjustment within a stand control time by the roll adjustment correction value.
