Abstract: The audible alarm device comprises a coupling assembly, a chamber assembly and an air horn assembly, releasably separable from each other. The coupling assembly and the chamber assembly are movable by squeezing action so that in one relative position pressurized air from an air inlet in the coupling assembly is allowed through a valve assembly into an interior chamber in the chamber assembly, the air driving a bi-stable piston into repeated contact with a percussion diaphragm, producing a below surface audible sound. An exhaust passage permits air to pass from the interior chamber to the surrounding environment. When the coupling assembly and the chamber assembly are moved by diver action to a second relative position, the exhaust passage is blocked, forcing air in the interior chamber to exhaust to the air horn assembly, which produces an audible sound above the water surface.

Abstract: A fuel vapor leak detecting device includes a pump, a housing having a pump passage connected to the pump, a switching valve, a pressure detector, and a control device detecting a shutoff pressure that corresponds to an interior pressure of the pump passage detected by the pressure detector when the pump is actuated while the switching valve is closed. The control device controls the switching valve to be opened at least once and to be closed at least once when the shutoff pressure is out of a specified range. The control device detects a fuel vapor leak when the shutoff pressure is in the specified range.

Abstract: Volatile liquid vapors formed during the pour of the volatile liquid from a volumetric test measure apparatus are contained in a pour vapor-containment apparatus that enhances the rate of vapor formation inside the pour vapor-containment apparatus. The interface between a flow control component on the test measure apparatus and a pour inlet on the pour vapor-containment apparatus creates a positive pressure, vapor-saturated environment so that a sufficient positive vapor pressure is maintained between the interior of the test measure apparatus and the pour vapor-containment apparatus when the flow control component is inserted in the pour inlet and the test measure apparatus is rotated about vertical during the pour and drain processes so that the vapor-saturated air formed in the pour vapor-containment vessel transfers during the pour into the interior of the test measure apparatus to replace the liquid that is poured out of the test measure apparatus.

Abstract: A test pressurization device (100) for hose (1) includes a first pair of press/driving rolls (10, 12) between which the hose can be inserted, and a second pair of press/driving rolls (20, 22) between which the hose can be inserted. The first pair of press/driving rolls (10, 12) is arranged on a distance from the second pair of press/driving rolls (20, 22). Further each pair of press/driving rolls is arranged for pressing the hose together between the rolls in conjunction with pressurization with a medium such as water so that a limited part of the hose, which is located between the first and the second pair of press/driving rolls, can be held pressurized and control of the hoses or its couplings tightness is admitted. Furthermore, while sections of the hose are held pressurized between the pairs of press/driving rolls, the same pairs of press/driving rolls are feeding the hose forward, thus checking the hoses tightness in a continuously moving section approach.
