Abstract: An irrigation device having a plurality of spans emanating from a common vertically oriented source of supply.

Abstract: An improved spill-resistant liquid bottle having a curved passageway and a vent passageway on the side in a curved neck having the shape of the number “7”, the letter “Z” or the letter “S” incorporated into the design of its mouth opening. This improved spill-resistant design allows a full bottle of liquid to be partially turned over with liquid level inside the bottle higher than the liquid level at the mouth opening, yet allowing no liquid to flow out from the bottle. Liquid will start to flow out only after the, bottle is turned further and the tilting angle reaches the predetermined start-to-pour angle. The start-to-pour angle is the tilting angle of the bottle when outside air starts to enter the bottle and liquid inside the bottle starts to flow out. This design makes pouring liquid from a full bottle much less likely to spill. The curved passageway creates additional flow restriction in comparison to ordinary bottles without such design.

Abstract: A vehicular fire extinguishing or suppressing device that includes a pressurized vessel that houses a flexible bladder and contains a fire extinguishing composition. A disk assembly blocks an axial bore between the vessel and its exit in order to retain the fire extinguishing composition in the vessel. If a fire is detected in the vehicle, the disc assembly is perforated by the discharge of an explosive charge. The perforation of the disk assembly allows the escape of the fire extinguishing composition.
