Abstract: This invention relates to an air missile comprising at least one temporary, releasable power unit, connected to the rest of said missile by a fit capable of allowing said power unit to slide parallel to its axis in the direction opposite said rest of the missile, wherein a communication is established between, on the one hand, the space inside said fit and disposed between the front of said power unit and said rest of the missile, and, on the other hand, the aerodynamic flow around said missile. The invention is more particularly applicable to the natural separation of said power unit from the rest of said missile.

Abstract: Apparatus for loading contact pins into a loading fixture, the pins in two or more rows, has a magazine for holding pins in a plurality of vertically stacked rows. Automatic insertion members push pins from the magazine into the loading fixture. The number of pins, and disposition of the pins, in a row can be predetermined by a template. The pins are swaged at a position intermediate the ends and thus do not stack level in the magazine. The magazine is provided with a stepped formation so as to offset the effect of the swage and provide for pins to be horizontal at the levels at which they are to be inserted into the loading fixture. Small rings of solder can be positioned on the pins prior to insertion in the board.

Abstract: Contact pins, of square cross-section and having a swaged portion nearer one end, are oriented so as to be fed to a magazine or other device with the ends nearer the swage portion all in the same direction. The pins move along channel-shaped grooves, over slots in the grooves. The slots have parts of different widths such that, the longer end of a pin falls down first, followed by the swaged portion end. In one orientation, with the swaged portion leading, the swaged portion holds the pin up over the slot until the longer end can fall down, while in an alternative orientation, with the swaged portion lagging, the longer end falls through as the pin moves over the slot.
