Abstract: A metal finishing barrel side opening has a cover secured by a series of cover and barrel tabs, the cover slid into a secured position with the cover tabs partially overlain by the barrel tabs. A locking handle assembly includes a graspable portion supported on a deflectable spring blade attached to the cover at one end which allows the handle assembly to move away from an aligned locator feature on the barrel as the cover is pushed into position. When the cover is shifted lengthwise, the handle assembly moves past the locking feature, and the locking blade pushes the handle assembly back down alongside the locking feature which then prevents reverse sliding of the cover back from under the barrel tabs. When the handle is pulled to initiate removal of the cover, the handle assembly is then moved out above the locking feature to enable the cover to be slid to the released position. An automation apparatus interacts with one form of the locking assembly to automatically install and remove the cover.

Abstract: A sheathed receptacle device for securing objects within an associated enclosure includes an object receptacle having outwardly-extending tabs which engage with respective slots in the enclosure to secure the receptacle within the enclosure. In a particular embodiment, the receptacle includes gripping portions integrally formed with the outwardly-extending tabs in a cantilevered body having a spring action such that manual depression of the gripping portions directly actuates the tabs into and out of respective slots in the associated enclosure.

Abstract: A housing and a housing assembly method of a heating or air-conditioning system of a motor vehicle has at least two housing parts that can be sealingly connected to one another along their separating plane. The peripheries of each housing part has a tongue and groove connecting members. The two housing parts are held together with the tongue and groove connecting members by displacing the two housing parts linearly relative to one another along the separating plane so that the tongue and groove formed around the peripheries of the two housing parts sealingly connect together. Locks or latches are provided in the tongue and groove connection to prevent the housing parts from inadvertently displacing along the separating plane.

Abstract: The invention concerns a stackable container consisting of a base box (1) and a lid (18) capable of being transported open in freight traffic and also filled and emptied once it has been stacked, and also of being closed and re-opened. For this purpose, the lid (18) consists of a cover plate (21) and a front wall (19) placed at right angles, said cover plate (21) is inserted, from the base box (1) open front face, into a peripheral groove (31) of the top edge, the base plate (4), has on its front ridge a supporting rim (10) provided with a ribbing (34) oriented upwards, just before reaching its closing position, the lid (18) being located inside the groove (31) widened in the side walls (2) rises slightly and when it drops after reaching its closing position, a projecting part (33) arranged on the inner front wall (19) lower edge (29) is engaged in the supporting rim (10) ribbing (34).
