Abstract: A mechanism for closing in sequence a first door (D1) and then a second door (D2) has pivot pins (40) mounted to the door frame. Each pin engages a cam plate (30), so that the plate can rotate. Linkages, such as doors arms (20) hinged from each door to the corresponding cam plate, cause the doors to close when the cam plates rotate. A pair of crossed shuttle arms (50, 60) are rotatably coupled to the cam plates. On the first cam plate the shuttle arms are fastened at a radial distance (d/2) from the pivot pin, and on the second the shuttle the shuttle arms are fastened at a greater radial distance (D/2). The two different distances cause the cam plates, as linked by the shuttle arms, to rotate at different angular rates. The door linked to the cam plate with the smaller distance closes first. The mechanism is asymmetrical with the distances from the pivots to the door arms, the lengths of the door arms, and the attachment points of the hasps on the two sides being in general unequal.

Abstract: A transportable safety gasoline container suitable for use in the workplace. The gasoline container has safety features that include, an automatically venting pour spout, a protective skirt on top of the gasoline container to prevent damage to valves and fittings, and a pressure relief cap which satisfies the various regulations associated with using gasoline containers in the workplace as well as for the transportation of such gasoline containers.

Abstract: A safety storage enclosure for housing containers of hazardous material is formed using wall components that have complementary edge formations that extend vertically and connect with elongate framing members to provide post-like supports. The wall components connect at their lower end regions with a welded, generally rectangular base assembly, and at their upper end regions with a correspondingly configured roof assembly, with the post-like supports strengthening the enclosure by providing rigid, columnar structures that extend from the base to the roof assembly. Front, back and opposed end walls of a variety of lengths can be formed using selected sets of "standard" wall panels and wall-corner panels, and "door panels" can be substituted for selected wall panels.

Abstract: A safety can for flammable liquid having a pressure relief cap which can lift slighly from the spout to form an escape orifice in response to internal pressure has its fire combatant properties enhanced by providing a skirt surrounding the location of the escape orifice. The skirt is located at such a level that it interrupts the radial spray pattern of flammable material spraying from the orifice and redirects this material in such a way that it tends to collect in the vicinity of the can.
