Abstract: A suspension ceiling grid system is disclosed which provides intersections including through-runners and oppositely extending runner ends. The through-runner is provided with a connector opening and the runner ends are provided with identical end connectors. The end connectors are engaged and disengaged by lateral movement and provide spring means which resiliently urge the end connectors toward the locked position.

The end connectors provide a second separate locking system which directly connects between the two end connectors. In one embodiment, a connector system is disclosed which allows easy removal of a runner within an assembled grid.

Abstract: A molecular model building set for the formation of models of molecules and compounds primarily in the field of organic chemistry is disclosed. The set includes dimensionally accurate model building members (10, 60) that are rotatable about their axes, and can be interconnected and/or interlocked to form specific molecular models.

Abstract: A support for an electrical busbar, made of plastic material, has a recess for holding a busbar. The lower surface of the recess is a resiliently flexible plate supported in the middle by a rib and provided with projections at opposite sides. Adjacent to the mouth of the recess is a resilient detent arm. When a busbar is inserted, it depresses the arm and at least one of the projections by flexing of the plate. The stress in the plate clamps the busbar in the recess, and the arm snaps into place behind the inserted busbar. One of the projections may serve as an end stop for the busbar, if the support is placed at the busbar end. This form of support is easy to manufacture and to use, and provides very reliable clamping and location of the busbar.

Abstract: An improved metal pallet is shown having elongate deck members defining a load bearing surface and transverse stringer members to support the deck members. The stringer members are generally U-shaped having generally upright laterally resilient sides defining longitudinally spaced-apart, transverse openings located adjacent to the upper marginal edges of the sides. The ends of the deck members pass through the stringer member openings. The deck members have longitudinal downwardly and outwardly disposed laterally resilient sides defining opposed pairs of parallel slot openings. The longitudinal spacing between these slot openings is different than the normal transverse spacing between the stringer sides, so that upon assembly of the pallet the stringer and deck member sides are laterally deflected; the peripheral edges of the stringer openings are located in the slot openings, and the deck members and stringer member are biased into mutual engagement by the lateral deflections of the respective sides.
