Abstract: A device is described which, when inserted under the rim of a toilet bowl in contact with the side wall thereof, uniformly distributes water over the surface of the bowl walls. This aids flushing material from the toilet. In many types of toilets, this also reduces the quantity of water required for each flushing operation. The device is flexible whereby installation and removal are facilitated in any shape of conventional toilet bowl.

Abstract: A low volume spray device for irrigation systems has a lower tubular end portion that is beveled to facilitate its insertion into a plastic conduit. Its upper end forms a nozzle portion with a small orifice and a deflector that controls the spray pattern. The device is preferably molded from plastic material so as to be inexpensive yet long lasting.

Abstract: A stream director is disclosed adapted for mounting on a rotary sprinkler head to redirect the water stream during a segment of the rotation of the sprinkler from its intended portion of the irrigation area to another portion. A plurality of closed adjacent smoothly curved channels are employed to confine and redirect the stream emanating from the nozzle prior to its break-up whereby the spray pattern from the sprinkler is substantially as if the sprinkler were rotating through only a portion of a circular area.

Abstract: A plurality of circumferentially spaced teeth are positioned in a predetermined manner on the end of a pattern-forming sleeve for a liquid discharge nozzle. Each of the teeth is provided with a stream-deflecting surface which is disposed to deflect portions of the discharge stream angularly into intercepting relationship with each other to increase the liquid particle breakup in the stream and improve the uniformity and homogeneity of the stream pattern.

Abstract: A sprinkler head for water spray cooling installations, attachable to a bottom wall of a hot water distribution conduit or distribution channel, the sprinkler head having a spray pipe reaching through an aperture of said bottom wall and a carrier shell or an open carrier cage surrounding the spray pipe and supporting one or several superposed cone-shaped spray plates at a short distance from the mouth of the spray pipe. Each spray plate has a pattern of spray distributor slots extending through its wall, so that a portion of the water passes through these slots and covers the central area underneath the sprinkler head, for an optimal distribution of the water.

Abstract: In a fluidized catalytic cracking unit a riser discharge head for discharging catalyst and hydrocarbon vapor from a riser conduit substantially vertically downward into a vertical reaction vessel such that erosion of the discharge head and the reaction walls is avoided.

Abstract: A system for spray cooling large quantities of heated water has a plurality of spray forming means each consisting of a plurality of associated nozzles connected by piping to pumps, each of the associated nozzles having an outlet constructed and arranged to discharge the water in a coherent stream which impinges upon the stream ejected by each other associated nozzle in a common zone beyond the nozzle with a force which breaks the streams into a spray of drops having a resultant trajectory away from the nozzles into a receiver. The water may be aerated before discharge from the nozzles, this being effectively accomplished by means of air inlets to a venturi passage in each nozzle.

Abstract: A free-jet-nozzle, particularly for the piston cooling system in reciprocating piston internal combustion engines, which is intended to forcibly bring about a vortex-free flow in the cooling medium flowing through the nozzle; the flow channel for the cooling medium is provided at least over a part of its length with radially inwardly extending, axially parallel ribs which leave open in the center of the flow channel a free cylindrical passage.

Abstract: A scraper nozzle which provides a high pressure, uniform sheet of water. The nozzle is preferably used in the upstream portion of the prewash zone of a warewasher. Wares, such as dishes, are contacted by the sheet of water and the materials on the dishes are scraped off. The nozzle comprises a planar surface and an arcuate surface. The arcuate surface terminates in a discharge edge which is characterized by a plurality of protuberances. The water flows across the discharge edge and forms the uniform sheet of water.

Abstract: A combination fuel introduction, distribution and air shaping device is provided for a fuel carburetion system of an internal combustion engine. The distributor is elongated and of generally inverted tear-drop cross-section. Fuel discharge openings are spaced longitudinally near or at the bottom of the distributor. Spaced-apart teeth aligned with the fuel openings or other means to prevent liquid bridging and depend from the bottom or discharge side of the distributor. The distributor extends across the intake air duct of an air-fuel mixing and modulating device that is adapted to deliver a mixture of finely divided fuel droplets in air to the intake manifold of an internal combustion engine. The body of the distributor divides the intake air flow into two converging air streams which entrain the fuel as liquid droplets sweeping it from the downstream side of the distributor and uniformly distributing the droplets in the air streams.

Abstract: A nozzle is disclosed in which streams of fluid are discharged from an apertured chamber into a skirt. The skirt has vanes to facilitate stream-like non-turbulent flow of the fluid. The skirt walls are divergent to allow for expansion of the fluid.
