Abstract: A measurement system includes an atomizer, an impactor, a particle counter, and a discharge reservoir. The atomizer has a liquid intake port and a gas intake port configured to aerosolize a liquid received at the liquid intake port. The impactor has an inlet coupled to the atomizer and has a first output port and a second output port. The impactor is configured to separate droplets wherein those droplets smaller than a selected cut point are directed to the first output port and those droplets larger than the selected cut point are directed to the second output port. The particle counter is coupled to the first output port and is configured to count particles larger than at least one particle size cut point. The discharge reservoir is coupled to the second output port.

Abstract: The present invention is directed to a method for additively fabricating a solid object from a series of components. The method utilizes additive fabrication with a programmed computer operating a machine to produce a solid object based on a three dimensional, computerized rendering of the solid object. Each component is produced from one or more molds which are filled with a fluid material that solidifies into a component that attaches to a previously manufactured component by way of the same process.

Abstract: An impact sprinkler has a nozzle connected to a housing and a discharge deflector member connected to a rotatable shaft assembly. The sprinkler has different replaceable nozzles and discharge deflectors for providing desired discharge characteristics. The shaft assembly and housing have contacting braking surfaces outside of the water flow providing a frictional braking force dependent on both water flow rate and pressure. The sprinkler has a deflection member for rotating an impact assembly relative to the shaft assembly while a pin supports the impact assembly at a position above the deflection member. A lower portion of the shaft assembly may be positioned in a recess in the housing such that a surface on the shaft assembly contacts a surface in the recess, and a highly wear-resistant material may be disposed on a surface of either the shaft assembly or the recess for providing improved wear characteristics.

Abstract: A rotary impact sprinkler is disclosed having a nozzle connected to a housing and a discharge deflector member connected to a rotatable shaft assembly without a dynamic seal between the nozzle and the deflector. The sprinkler may be provided with different nozzles and discharge deflectors that are easily removed and replaced for providing desired water flow and discharge characteristics. The shaft assembly and housing may have contacting braking surfaces outside of the water flow. The braking surfaces may provide a frictional braking force dependent on both water flow rate and water flow pressure. The sprinkler has a rotatable impact assembly supported by the shaft assembly and including a deflection member for rotating the impact assembly relative to the shaft assembly. The shaft assembly may have a pin for supporting the impact assembly at a position above the deflection member.

Abstract: An impact sprinkler drive is provided by an impact arm or spoon that rotates out of and counter-rotates into a water stream to impact and forward re-align a water emission portion from which the water stream emits. The impact arm is designed to, upon sufficient rotation, interfere with the water stream to reduce back-impact and reverse re-alignment of the water stream. The impact arm may be an impact spoon formed on an impact disc. The impact spoon is configured to increase the energy for forward re-alignment of the water emission portion including an increased length to permit a time delay before water flowing through the spoon applies force away from the water stream. The water acts upon spoon portions positioned at increased radial distances so that the water acts with a greater torque arm to impart rotational energy.

Abstract: Apparatus and method for collecting magnetometer data at the earth's surface in order to detect anomalies in the earth's magnetic field caused by buried ferromagnetic objects. A plurality of magnetometers are provided in a predetermined array on a mobile platform. A fixed station is also provided on the earth's surface, and navigational data from a global positioning system (GPS) is collected on the locations of the fixed station and mobile platform in synchronization with a sync signal received from the GPS. While the mobile platform traverses an area on the earth's surface, magnetometer data is collected in synchronization with the sync signal. The apparatus and method provide a significant improvement in the amount of area which can be surveyed in a given time period and in the precision of the location and magnetic field intensity data collected.
