摘要:
A hose-fed lateral move irrigation system and method that utilizes a pipe with a plurality of sprinklers attached to a wheeled cart that pulls a flexible-hose assembly therebehind using at least one onboard winch and travels laterally with the pipe and sprinklers relative to a field so that a sufficient amount of hose may be used to enable total automation of the system.

A riding lawn mower mounted drop spreader apparatus is used for spreading a granular material while mowing. The spreader includes a hopper for holding a quantity of a granular material to be dispensed with a control gate which controls the amount of material distributed while mowing. An auger located in the hopper has a drive motor which can also be controlled by an operator of the mower. The hopper has a mounting frame for mounting the hopper and agitator mechanism on a rear chassis region of the lawn mower. An operator can visually observe the amount of material distributed by observing the mowed path behind the mower during use.

The aircraft emergency oxygen supply system includes one or more sources of supplemental breathable oxygen, one or more inlet valves for one or more breathing devices, connected to the inlet valves, and one or more cabin air pressure transducers. A pressure controller controls the inlet valves in response to the one or more cabin air pressure transducers. One or more second pressure transducers may connected to conduits downstream of inlet valves to be monitored, and the pressure controller may also control operation of the inlet valves in response to the one or more second pressure transducers.

A portable pressure washer that includes a base and a tank assembly formed as a one-piece structure and for engagement with the base. The tank assembly has a pair of water tanks that are disposed separately from each other and a solution tank that is disposed between the pair of water tanks. Each of the tanks is provided with a filler cap. A latch mechanism is disposed at opposite ends of the base for releasably securing the tank assembly with the base. The base houses a liquid pump and air compressor. A manual selector is mounted at the base and has separately selectable positions for coupling either with the water tanks or the solution tank. A spray hose is coupled from the pump for directing either of the water or solution when the pump is activated.

A dry mixture for use with water has been developed to be used as an erosion control spray matrix for reducing erosion of sandy soils while awaiting development of a root system of plants to hold the soil in place. The dry erosion control mixture includes alpha-calcined calcium sulfate hemihydrate, a non-gypsum binder polymer; biodegradable fibers; and wood fiber mulch. An erosion control slurry is applied to an area of soil in need of erosion-control. After obtaining the dry erosion control mixture, it is mixed with water to form erosion control slurry. The ratio of the composition to the water is preferably from about 1:8 to about 1:12. Seed is distributed over the soil and the erosion control slurry is applied over the distributed seed.
摘要:
To mix immiscible materials at low pressure, the materials are applied from separate inputs of a fixture to separate channels where they are permitted to flow to and spread over surfaces or edges at selected thicknesses. On the surfaces or edges the materials are each subject to flowing air that forms small particles or drops even though the materials may be viscous. The particles or drops are mixed together and may be applied to a combustion device or spray device or any other device utilizing the mixture.

A novel groundcover seed mixture and method of application comprising mixing visual powdered indicator with small groundcover plant seeds thus allowing a more even and visible application of the groundcover plant seeds over the desired ground surface area.
摘要:
A includes a main body portion defining a waste holding chamber, a vent path extending from the waste holding chamber to atmosphere, and a float member. The float member is coupled to the tank for movement between a first position and a second position. The float member is movable from the first position to the second position in response to an increase in fluid level within the storage chamber. The vent passage remains open for venting the storage chamber when the float member is in the first position and is blocks the vent passage in the second position.
