Publication number: 20130240220Abstract: A low profile explosion proof by containment enclosure includes a base wall having first and second edge sections that are joined with third and fourth edge sections to define a substantially planar surface. First and second side walls extend from the first and second edge sections, and third and fourth side walls extending from the third and fourth edge sections and are joined with the first and second side walls. The base wall, first and second, and third and fourth side walls define an interior zone. A cover is coupled to the first and second, and third and fourth side walls to enclose the interior zone and provide containment to any flammable events. At least one of the first and second side walls, third and fourth side walls, base wall, and cover includes one or more unobstructed openings that provide fluid drainage while also providing containment to any flammable events.Type: ApplicationFiled: March 16, 2012Publication date: September 19, 2013Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: Melissa Loureiro, Thomas E. Powell

Publication number: 20130228346Abstract: A tank assembly for containing liquid with increased heat resistance includes a lightweight container for liquid having an inlet and an outlet, and a spray assembly. The spray assembly includes means for spraying a liquid, also called a spray device, inside the container that is fluidly connected to the inlet. The spray device has an orifice located so as to direct liquid received from the inlet against an inside surface of the container walls. The liquid forms a sheet that flows down the walls of the container to a pool of liquid to reduce the temperature of the walls of the container above the pool.Type: ApplicationFiled: March 1, 2013Publication date: September 5, 2013Applicant: Parker-Hannifin CorporationInventor: Richard E. Scott

Patent number: 8524105Abstract: Compositions are described which are useful in many applications such as fire extinguishing or refrigeration. The compositions may include a hydrochlorofluorocarbon such as 2,2-dichloro-1,1,1-trifluoroethane, a dispersant such as CF3I, and an inert gas such as argon, and may in some embodiments be held under pressure. For example, some fire extinguishing compositions may be composed of 2,2-dichloro-1,1,1-trifluoroethane, CF3I, and argon.Type: GrantFiled: January 13, 2012Date of Patent: September 3, 2013Assignee: American Pacific CorporationInventors: Jeff Gibson, Bradford Colton

Patent number: 8517116Abstract: An inertization method for preventing fire or explosion in a first enclosed protected area by lowering the oxygen content in the protected area to a base inertization level relative-to the ambient air. With the objective of eliminating any danger to people or processes within the protected area, the method according to the invention provides for measuring the oxygen content in the protected area, comparing it to a threshold (maximum inertization level), and in the event it falls below the threshold (maximum inertization level), introducing fresh air into the protected area(s).Type: GrantFiled: November 3, 2005Date of Patent: August 27, 2013Assignee: Amrona AGInventor: Ernst Werner Wagner
