Abstract: A storage system for liquid is disclosed which includes an external containment vessel which is open on top and an internal storage tank mounted within the external containment vessel so as to extend above it. The internal tank and the containment vessel are constructed and arranged so as to have a substantial outer storage space formed between them. This storage space is covered by a roof structure which extends from a point below the top of the internal storage tank to cover the containment vesel. A venting structure is provided at a location on the internal tank above the roof structure, where it is exposed to the atmosphere, and a drainage structure provides liquid coupling from the venting structure to the outer storage space.

Abstract: A wall bracket for mounting an electrical connector for data or communications in an aperture in a wall panel has a box-like body of sheet metal with a base and opposed end walls extending forwardly therefrom. Each end wall has a front mounting flange extending substantially perpendicularly from a front end thereof in an outward direction, and the base having an opening and a pair of mounting tabs extending in opposite directions in the opening from opposite ends of the opening. Each mounting tab has a length sufficient to enable the tab to be bent rearwardly through substantially 180.degree., after the bracket has been positioned in a wall panel aperture to position the front mounting flanges against a front face of the panel, to cause the tabs to engage a rear face of the panel as rear mounting flanges and enable securing devices to be passed through the front mounting flanges, the wall panel and the rear mounting flanges.

Abstract: A padlock cover with storage compartment, having a first portion which covers the case of a conventional padlock, this first portion having a pair of openings for passing the legs of the padlock shackle. The cover has a second portion having spaced apart walls that define a storage compartment, with an access opening in one wall. A flexible, resilient, elongated lid member is mounted in guide means such that it has a closed position in which one end portion covers the storage compartment opening and the other end abuts the releasably locked leg of the shackle to hold the lid closed; and the lid member being slidable to an open position in which the compartment opening is uncovered when the shackle leg is released from the padlock case thereby unobstructing further guided movement of the lid.

Abstract: A food container comprises top and bottom members, with the bottom member including a lower base wall and an upwardly extending side wall. Spaced apart downwardly extending depressions are formed in the lower base wall, and each of these depressions has an inside wall surface spaced inwardly from the surrounding side wall. The inside wall surfaces of the depressions collectively define an outline, and the top member has a raised central portion the outline of which is substantially identical to but slightly smaller than the outline defined by the depressions. This relationship enables the raised central portion of the top lid member to interlockingly fit between the depressions when assembled food containers are stacked one above the other. The raised central portion of the top lid member has less height than the depressions which spaces the lower base wall from the raised central portion when assembled containers are stacked.
