Abstract: A secondary containment in which gasoline passes from a storage tank through an underground pipeline past an impact valve to an inlet of a gasoline dispenser includes inner and outer pipelines. The inner pipeline includes a rigid segment connected to the storage tank at one end and a flexible pipe segment at its other end. The flexible segment further connects to an additional pipe segment which passes through the bottom of a gasoline containment box to an impact valve housed therein. The impact valve, in turn, leads to the dispenser inlet. The box is installed below the dispenser, and the flexible segment connects to the additional pipe segment at a point below the box. The flexible segment is removed from the outer pipeline by disconnecting it from the rigid pipe segment, then disconnecting the impact valve from the dispenser inlet and box, and removing the impact valve from the box. The additional pipe segment and the flexible pipe segment are thus pulled through the bottom of the containment box.

Abstract: An apparatus and a method for collecting in seal containers the gasoline that leaks or spills from service station dispensers or submersible pumps help to reduce the pollution associated with such equipment. The apparatus and the method also provide for returning the collected gasoline to the storage tanks via existing vapor recovery systems.

Abstract: A tool for installing an object for example a flammable fluids containment box in a form for a concrete structure has an elongated bar oriented horizontally, and four slidable assemblies mounted on it. Two outer assemblies each have a horizontal rod section around the bar and a T-screw or allen head bolt for fastening the rod section in place on the bar. The outer assemblies have a mechanism to engage a lip of the form, and a mechanism to support the assembly on the ground outside the form if the form is lipless. The inner assemblies each have a horizontal rod section that fastens in place on the horizontal rod, and has a vertical rod attached to its underside. At the bottom of the vertical rod is an assembly for fastening the containment box such that the tool thus suspends the containment box in position in the form, so that the box will set in place in the concrete.

Abstract: A gasoline pump computer reset lock apparatus has a mounting bracket for being attached inside a gasoline pump housing. A bolt or plunger is moveably positioned in a plunger housing attached to the mounting bracket. The plunger is in a locked position when one of its ends is closed against a stop and is in an unlocked position when that one end is spaced back from the stop. A control apparatus is coupled to move the plunger to the locked or unlocked positions. One end of a link is attached to a rotatable crank member. The crank is coupled to a reset lever so that the link moves into the space between the plunger and the stop when the reset lever is rotated. The link is moveably attached to the mounting bracket so that when the plunger is in the locked position against the stop, the forward end of the link encounters the plunger and is prevented from moving into the space.
