Abstract: The invention is for a method for firefighting in which a directed jet of extinguisher foam is applied so as to cover the source of the fire, and to a device suitable for implementing this method. The method and device make it possible to extinguish fires which are spreading in area, while at the same time reducing the risk of uncontrolled spread of the fire. According to the invention, this is achieved in that as a supplement to the jet of extinguisher foam, the apparatus discharges individual jets of a mist of firefighting liquid which cools down the space surrounding the source of the fire.

Abstract: A retaining supporter of a rotary sprinkler is disclosed. The retaining supporter has a cruciform cylindrical base at the lower half of the rotary sprinkler. Two plates with equal length are crossed with each other so as to form a cylindrical member with a cruciform cross section. The width of one plate is thicker than the other one, and the vertical surface of the wider plate is a curved surface and has a shape like an inverted triangle. When the lower half section of the fixing supporting element in inserted into the soil, it can be inserted easily. When the top section of the rotary sprinkler is connected with water pipe for water flow, the water flows through the interior of the fixing supporting element of the rotary sprinkler, so that water can be sprayed from the water outlet of the rotary sprinkler and moves the rotary sprinkler.

Abstract: A lawn irrigation sprinkler head that internally incorporates an alert and retrieval device which indicates the position of the head if damaged, and facilitates in-situ repair of the damaged head. The sprinkler head has a hollow body containing a pop-up riser connected to a nozzle. The alert and retrieval device is positioned between the base of the riser and the nozzle. Should the nozzle become damaged or dislodged, the alert device telescopically extends from the riser and signals the location of the damaged sprinkler head. The device facilitates the repair of the head by lifting the riser from within the sprinkler head so that a replacement nozzle can be attached. In an alternative embodiment the alert device has an integral shut-off valve which prevents the discharge of water in the event that a subsequent irrigation cycle occurs before the damaged head is repaired.

Abstract: A watering nozzle (16) for underground pop-up sprinkler (1) comprises a bottom part (17) and a top part (37) comprising a distribution cylinder (40). The bottom part (17) is provided with an annular opening (100) that receives the flow of water coming from the base of the sprinkler (1) and generates a jet in the form of a spray having pre-established angular extension that flows into a distribution cylinder (40) provided with radial slots (41) arranged as an arc of circumference that proceed from its bottom to its side wall so as to subdivide the single spray jet into single jets. The distribution cylinder (40) has on top a fan wheel (70) having a diameter greater than the cylinder and provided with external fins (71) that extend downward.

Abstract: A fountain includes a container having a top with an opening therein, a bottom, and an interior for holding a liquid, such as water. An elongated, hollow support member is positioned within the interior and extending from the opening in the top. This support member has a first end mounted at or near the bottom of the container, a second end terminating a predetermined distance above the opening in the top, and an exterior surface over which liquid flows. A pump positioned within the interior and operably connected to the first end of the support member pumps liquid in the interior into and through the hollow support member to flow out its second end and then along the exterior surface of the support member to return to the interior of the container. A faucet is attached to the second end of the support member in a manner which allows the liquid to flow from the second end.

Abstract: A dishwasher spray arm hub assembly includes a hub having a first central bore extending therethrough and a conduit feed extending therefrom. The conduit feed is in flow communication with the central bore and a venturi insert is disposed in the hub central bore. The venturi insert also includes a second central bore extending therethrough. The first bore and the second bore together form a fluid bypass channel in flow communication with the conduit feed. Therefore, a lower spray arm assembly and a spray arm conduit for upper spray arm assemblies may be simultaneously fed through the hub assembly.

Abstract: A shower head having a plurality of nozzles capable of attachment to a flexible shower arm. The shower head has a unique nozzle construction that allows for the manipulation of an external flexible nozzle to remove mineral deposits and has an internal, rigid nozzle structure for efficiently forming an aesthetically pleasing water stream. The shower head may have two available flow configurations which are selectable by a valve.

Abstract: An aerosol device for dispensing texture material for matching existing acoustical ceiling texture. The device comprises a container, a valve assembly, a dispensing nozzle, a hardenable material, and pressurized inert gas as a propelling mechanism. The hardenable material and pressurized inert gas are placed into the container. When the valve assembly is opened, the inert gas forces the hardenable material out of the container through the dispensing nozzle. The dispensing nozzle diverts at least a portion of the hardenable material exiting the container to develop a spray suitable for the application of the hardenable material onto the ceiling surface being textured. The hardenable material preferably comprises at least water, filler, binder, and polystyrene particles. The inert gas is preferably nitrogen.

Abstract: Disclosed is a crop spraying system. The system includes an articulated spraying assembly that is secured to a tractor and/or a pull behind crop sprayer. The articulated assembly permits a fluid, such as an insecticide, to be effectively delivered to a commercial crop, such a citrus tree. Specifically, the fluid can be delivered upwardly from a pivotal boom that is preferably horizontally positioned at a location adjacent the ground. In this manner, the fluid is released upwardly from a position beneath crop canopies. The result is a more effective penetration of the crop by the dispensed fluid.

Thus, the user can operate the push button by his one hand only, so as to switch and adjust the water flow, thereby facilitating the user switching and adjusting the water flow of the shower head. In addition, the user can press the push button to switch and adjust the water flow through the first water outlet panel, the second water outlet panel and the third water outlet panel, thereby enhancing the versatility of the shower head.

Abstract: Within an injector housing, a nozzle needle comprising a nozzle needle shaft is accommodated in a first guide boring in a longitudinally displaceable manner. A nozzle prechamber which is arranged in front of the nozzle needle shaft and which is situated on the fore-part of the first guide boring is supplied with fuel via a high pressure channel. A control valve permits a control chamber, which is coupled to the nozzle needle and which is subjected to the action of highly pressurized fuel, to be relieved from pressure by opening the nozzle needle. According to a second embodiment, a spring chamber is configured as a high-pressure chamber on the rear side of the first guide boring that guides the nozzle needle shaft. The spring chamber is separate from the control chamber and contains a readjusting spring that impinges upon the nozzle needle in a direction of closure. This configuration prevents fuel exiting the nozzle prechamber from overflowing over the guide boring which guides the nozzle needle.
