Abstract: A tool for extracting a microelectronic chip carrier from a receptacle to which it is connected. It includes left and right arms, each having coextensive members in the form of a substantially rigid tong and a flexible leg. Both arms are pivotally mounted at a common axis for relative movement. A distant end of each tong terminates at a chip carrier engaging hook and is slidably received in a channel formed in a tong support at a far end of the leg. Each leg has a bearing surface at its extreme end and a hinge member intermediate its ends and is bowed outwardly of its associated tong. With the bearing surface engaged on the receptacle, the arms are opened sufficiently wide that the hooks which are extended from the bearing surface when the tool assumes its relaxed condition, straddle the chip carrier.

Abstract: Apparatus and method for feeding a single electrical wire or a plurality of electrical wires including a feed roller means and a pressure roller means. A length of wire placed between the feed roller means and the pressure roller means is driven by the feed roller means while the pressure roller means is biased toward the material keeping the material in driving contact with the feed roller means. The pressure roller means includes means for adjusting its position automatically as the material varies in size. In the case where a plurality of lengths of wire is fed by the feed roll means, each length of wire has its own pressure roller means which independently adjusts itself to the varying size of the material being fed thereby.
