Abstract: A device for reducing the rotational speed of an ammunition unit, for instance a submunition unit, and at the same time imparting to the ammunition unit a lateral speed includes a body arranged to be swung out from the ammunition unit and be released in a specific outswung position. The body preferably consists of a band which is wrapped about the outer peripheral surface of the ammunition unit. One end of the band is fixed to the ammunition unit in such a way that the band is released in a specific outswung position.

Abstract: The reactance of series capacitor equipment connected to an electrical transmission power line can be changed during operation with the aid of a transformer on-load tap-changer which switches in or out a variable number of capacitor modules. The tap-changer comprises a tap selector, the contacts of which in currentless state can be moved between the capacitor steps, and a diverter switch with a plurality of sequentially operating contact members and with resistors arranged to prevent direct short-circuiting of the capacitor steps. The tap-changer can be at line potential and operated remotely by contact-moving means at ground potential.
