Abstract: An apparatus for inserting IC packages into sockets on a burn-in board and for extracting IC packages therefrom includes a plurality of loader/unloader mechanisms affixed to a rotatable platform, the platform being adapted to support one or more burn-in boards and to position sockets mounted on the burn-in boards beneath the loader/unloader mechanisms one row at a time. The loader/unloader mechanisms include a vacuum means for lifting IC packages and pneumatic cylinders for transporting the packages to and from the burn-in boards. IC packages are gravity fed along a delivery channel both to and from the loader/unloader mechanisms by rotation of the platform.

Abstract: A head assembly for a burn-in board loader and unloader comprises a mounting block having a generally vertical track. A main body is mounted on the mounting block and afforded vertical movement along the track. The main body has a vertical bore through which a vertically movable plunger extends. The main body also comprises at least three vertical mounting wire holes spaced-apart around the bore. A floating crown having a vertical bore through which the plunger extends is mounted on the upper end of the main body by mounting wires which are fixedly attached at their upper ends to the crown and extend downwardly into the mounting wire holes. The mounting wires are fixedly attached at their lower ends to the main body at the lower ends of the mounting wire holes. The crown is preferably mounted to provide a gap between the crown and main body of about 0.005 inch.

Abstract: A device for preventing liquids or liquid-like substances splashed out of a bowl or basin from falling onto a background surface includes a base for supporting the device around a portion of the bowl or basin. A shield portion is attached to and extends upwardly from the base between the bowl or basin and the background surface. The base may include legs on opposite sides of a cutout in the shield portion for allowing access to a faucet or other fixture. The shield portion may be provided with an overhang folding back over the bowl or basin from the top of the shield portion, such overhang having a lip disposed vertically over the bowl or basin. The shield portion may include a rear shield and two side shields attached substantially perpendicularly to the base and to one another, and the base may include a lip for extending over an edge of the basin. The device preferably is made of a transparent or translucent material, such as acrylic plastic, safety glass, or the like.
