Abstract: A combustor for a small gas turbine engine in which a compressor discharges a swirling air flow into the combustor, and a fuel impeller is rotatably connected to the compressor and slings atomized fuel into the combustor in a direction to produce a stagnation zone within the combustor. A plurality of fuel injectors delivers fuel to the inlet end of the fuel impeller.

The fuel impeller produces a very fine mist of fuel and the stagnation zone produced results in easy starting of the engine and stable combustor burning.

The first electrode ink composition contains at least one electrode active material and the second electrode ink composition contains at least one binder material. The two ink compositions are deposited in combination to form one of a positive electrode and a negative electrode layer. The resulting electrode is suitable for use in a battery.

Abstract: A liquid manure applicator comprises a tank for holding a supply of liquid manure that is distributed onto a farm field through a distributor having a plurality of distribution ports and hoses. The hoses lead to individual distribution tools that include a pair or rotary coulters and a bellows for applying downforce to the coulters. The distributor includes a ring that restricts the size of the solids entering the distribution ports and hoses to something substantially equal to or less than 50% of the cross-sectional area of the hoses. This prevents the hoses from plugging even when small diameter hoses are used to lower the application rates to values more consistent with the needs of a zone tilled field. A rotary chopper in the distributor reduces the size of larger solids until they have been broken up into pieces small enough to pass the restriction provided by the ring.

Abstract: An impeller system is provided for the delivery of a fluid, such as liquid manure, through a manifold system to a plurality of hoses. The impeller includes multiple blades for driving the fluid toward the manifold outlets. The impeller also includes a plurality of shut-off gates to close off multiple outlets and, therefore, increase the pressure to the remaining outlets. As the impeller rotates, openings to various outlets are opened and closed, thereby increasing the pressure of the fluid delivered to each of the outlets.

At least a subset of the plurality of tubes are operatively-coupled to the integrating member for coordinated movement of the coupled tubes in the respective plurality of fluid outlets.

The second fluid is sprayed from the rotating arm into the stream of first fluid that flows across the lands, and is thereby atomized. In another embodiment, the arm comprises a land stepped into the trailing edge thereof, and a port for injecting the second fluid is located on the land. In another embodiment, the land comprises a groove located between the port and an associated riser surface stepped into the trailing edge. In another embodiment, the arm comprises a port in the trailing edge thereof from which the second fluid is injected, and a groove is located on the trailing edge in a radially increasing direction from the port.

Abstract: A fluid delivery device providing a pulsating discharge. The device comprises a housing having an elongated chamber, a fluid inlet passage to the chamber, and a cylindrical rotor mounted in the chamber and comprising a plurality of grooves. The inlet passage comprises a first fluid injection channel through which the fluid enters the chamber and impinges upon the grooves in the rotor. The fluid thereby rotates the rotor and exits as a fluid pulse through a linear fluid discharge. The grooves in the rotor may be helical such that the pulse of fluid traverses the linear fluid discharge from one portion to another or sequences through a linearly aligned plurality of fluid exits. The device may further comprise a second fluid inlet passage adapted to inject a second fluid into the grooves. One fluid may be compressible and one non-compressible. A method for cleaning an object, such as a circuit board, using the fluid delivery device of the present invention is also disclosed.

Abstract: The present invention provides a spray head assembly with a moving spray nozzle that delivers fluid in a substantially uniform spray distribution. The movement of the spray nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the spray housing and nozzle to wobble. The spray pattern produced by the wobbling spray housing changes more or less rapidly so that fluid droplets or streams are directed along arcuate paths rather than at a single point. This type of spray distribution pattern is gentler than many stationary patterns and the unique design of the wobble inducing member does not include complex mechanical parts or significant flow restrictions.

Abstract: An apparatus is used for distributing a slurry flow to plural feed conduits. It has particular application in the injection of swine manure into the soil as fertilizer. The apparatus includes a circular manifold with a central inlet for delivering slurry to the manifold and outlet ports spaced around the outer wall of the manifold for connection to the respective feed conduits. An impeller in the manifold has back swept impeller blades mounted for rotation so that the impeller blades sweep in sequence past the outlet ports. The impeller blades produce pressurized zones in front of them as they sweep in sequence past the outlet ports. This produces a pulsating flow in the feed conduits, ameliorating blockage problems with the conduits. The impeller also includes knives that rotate around the inside of the outer wall and anvils mounted on the outer wall so the knives will act with the anvils to sever trash in the slurry flow. The knives and the anvils are oppositely inclined to produce a shearing action.
