Abstract: A process is provided for the production of metalorganic compounds by reacting a Grignard reagent with a Group II, Group III or Group V metal halide in a tertiary alkyl amine solvent to form a metalorganic adduct, isolating the adduct and dissociating the adduct to leave the metalorganic compound.

Abstract: A circuit board locating assembly for locating a circuit board during a manufacturing operation such as a solder paste printing operation performed on the board, the locating assembly comprising a tooling platen for supporting during the operation a plurality of individual board support means, a magazine for storing the board support means when the board support means are removed from the area in which the board is supported during the operation, and conveying means adapted to convey the board support means from the magazine and to position the board support means in selected positions on the tooling platen.

Abstract: A tool for aligning the leads or pins of a connector while they are inserted in the holes of the electronic package to which the connector will be attached is described. Guide rails, which are attached to a fixed-block on one end and a removable slidable block at the other end, are placed between the leads to align them in one direction. A comb having protruding teeth is positioned so that the teeth are placed between the leads in a direction perpendicular to the guide rails. The guide rails and teeth align and constrain the leads in the same pattern as the holes of the package and a clamp holds the guide rails and teeth in place. After the leads have been started to be inserted in the holes of the electronic package the comb is removed. The slidable block is removed from one end of the guide rails, and the guide rails are pulled out of their position between the leads. The connector leads are then fully inserted into the holes.
