Abstract: A frusto-conical strainer is mounted on the lower end of a pop-up riser for filtering out debris from water entering the lower inlet end of a surrounding outer housing to prevent clogging of the nozzle orifice or damage to mechanical components within a sprinkler. A cylindrical scrubber including a circumferential array of resilient arms is anchored at the lower inlet end of the outer housing. Wiper blades on the upper ends of the arms press against the outer surface of the strainer to scrape debris and algae therefrom as the riser extends and retracts. The strainer may have finer and coarser mesh sections for different levels of filtering in a sprinkler having multiple internal water flow paths. A plurality of circumferentially spaced projections on the strainer deflect past a plurality of circumferentially spaced ribs formed on the interior wall of the outer housing to provide a riser ratchet mechanism.

Abstract: A mold spraying system for emitting one or more sprayable materials onto portions of a mold, such as a die-cast mold, while the mold is located in a molding machine. The spraying system has an emitter, such as a spray head, for directing the one or more materials onto portions of each half of the mold when the mold is in an opened position between molding cycles of the molding machine. The spray head is connected to a manipulator for positioning the spray head between the mold halves. A pressure boosting unit is employed to ensure that the sprayable materials are supplied to the spray head at a sufficient pressure, notwithstanding any system pressure losses and/or the high frequency of spraying operations required to be performed as a result of a short molding machine cycle.

Abstract: The invention relates among others to a method for producing outlet openings (32) in a valve, in particular a fuel injection valve. The injection valve has a fuel inlet (2), an excitable actuating device (1, 2, 19) by which a valve closing member (28) is movable, a fixed valve seat (27) embodied on a valve seat element (26), with which seat the valve closing member (28) cooperates to open and close the valve, and at least one outlet opening (32), as a fuel outlet, provided downstream of the valve seat (27). The at least one outlet opening 32 is produced in such a way that in a first method step, a through hole is created in the valve seat element (26), and in a second method step, from the ejection end of the through hole, an outlet region is created that is altered in shape and/or size and/or contour compared to the through hole.
