Abstract: A drawer partition includes a molded, one-piece, plastic tray with a base wall and upstanding side walls. The side walls have laterally aligned and longitudinally spaced-apart dovetail-shaped grooves in the inner surfaces thereof slidably mateable with dovetail-shaped tongues at the ends of divider panels for dividing the tray into compartments. Pairs of ribs define slots on the side walls to receive end edges of the divider panels. Pairs of flexible legs on the bottom edge of the divider panel are snap-fitted into apertures in the base wall to lock the divider panels in place. The bottom outside edges of the side walls have longitudinal grooves mateable respectively with the upper edges of the side walls of another partition to facilitate guided longitudinal relative sliding movement of stacked partitions. Each tray has front and rear end portions which respectively have recessed outer and inner surfaces to permit overlapping nesting of the ends of longitudinally aligned partitions.

Abstract: A tool cabinet has rollers depending from a bottom wall for rolling engagement with an underlying floor. A retractable step has depending legs and spring-loaded casters which support the step so that it can freely roll except when weight is placed on the step driving the legs into engagement with the floor. The step has a vertical slot in which is received a depending arm of an angle bracket which is fixed to a roller slide assembly mounted on the underside of the cabinet so that the step can be horizontally rolled between a stowed position beneath the cabinet and an extended position extending from beneath the cabinet and can move between raised and lowered positions when extended.

Abstract: The modular electronic device includes a main unit and at least one plug-in module adapted to be removably slid on to and mounted on the main unit. There are first and second interfitting connectors respectively on the main unit and the module which automatically interfit when the module is mounted. First and second interfitting track structure are respectively on the module and main unit to facilitate sliding the module onto the main unit. Finally, there is first and second interfitting latching elements respectively on the main unit and the module to hold the module latched in place.

Abstract: A clamp-type ammeter probe includes two opposed jaws interconnected for pivotal movement between open and closed conditions and biased to the closed condition, with each of the jaws being of unitary one-piece molded construction. Each jaw includes a magnetic core unit comprising a core segment molded to a spacer segment and fitted within a channel-shaped shield segment to form a unit which is then molded between an outer shell and an inner segment of the jaw for encompassing the core unit except for exposed end portions thereof. These exposed portions on one jaw mate with those on the other jaw when the jaws are closed so that the core segments form a magnetic loop to encircle an associated conductor while the shield segments form a shield path encompassing the core loop. Stop surfaces on the inner segments provide a gap in the core loop in which a magnetic sensor is disposed.

Abstract: The wrench holder comprises a pair of elongated, plastic members that slide or telescope together. Each of the members includes a body and a pair of bifurcated legs extending therefrom. The members pass through openings in a set of wrenches and telescope or slide together. Heads respectively at the ends of the elongated members retain the wrenches therebetween. A latching element at the distal ends of the legs and another latching element on the body in the region of the head enable the two members to be releasably interconnected.
