摘要： Sprinkler head mounting system for connecting a sprinkler head to a horizontal water supply pipe in an irrigation system (e.g., an agricultural irrigation system). In one embodiment the mounting system includes (a) a U-shaped tubular member connected to the water supply pipe, (b) a flexible tubular member coupled to the U-shaped member, (c) a conduit having inlet and outlet portions, (d) a riser connected to the outlet portion of the conduit, and (e) a counter-weight carried by the conduit for balancing the weight of the riser and sprinkler head. The mounting system prevents vibration from the sprinkler head from being transmitted to the water supply pipe.

摘要： A filtering system for filtering particles from a flow of fluid is disclosed, and includes a filter device for removably positioning in a lumen of a pipe carrying the flow of fluid. The filter device has an upstream side for positioning in an upstream direction of fluid flow and a downstream side for positioning in a downstream direction of fluid flow. The filter device comprises a perimeter rim extending along the perimeter edge of the filter device and defining an opening, and a plurality of filter bars extending across the opening to form a plurality of slots therebetween. Each of the filter bars of the plurality of filter bars has a transverse cross sectional shape. The transverse cross sectional shape has a transverse width toward the upstream side of the filter device that is relatively wider than the transverse width toward the downstream side of the filter device.
