Abstract: For testing electronic chips, an integral plastic test clip comprises a pair of opposed jaws that are pivotal relative to each other about a junction and that are provided with (1) inner elongated grooves radiating from the junction for the snug reception of the similarly located terminals of the chip, (2) openings through which the clip communicates with the grooves to guide probes into direct contact with selected terminals, and (3) indicia at the openings for facilitating accurate terminal selection while precluding inadvertent probe and terminal contacts.

Abstract: An apparatus for gluing a stack of aligned sheets into a pad or book with a molten adhesive, comprising means for clamping said sheets with the aligned edges to be glued facing downwardly, a crucible for adhesive, means for melting said adhesive in said crucible, a glue applicator roll dipping into the molten adhesive in said crucible and extending above said adhesive, and means for effecting relative movement between said clamping means and said crucible with said applicator roll, whereby said applicator roll applies adhesive to the aligned edges of said sheets. The crucible and applicator roll, preferably with an upstream air blower, are desirably positioned between a pair of parallel endless chains which are moved below the stationary sheets.
