Abstract

Amplitudes of drive pulses received by a horizontally-placed dropper determine the horizontal displacements of droplets relative to an ejection aperture of the dropper. The drive pulses are varied such that the dropper generates a two-dimensional array of vertically-falling droplets. Vertical and horizontal interdroplet spacings may be varied in real time. Applications include droplet analysis experiments such as Millikan fractional charge searches and aerosol characterization, as well as material deposition applications.

Apparatus and method for heterodyne-generated two-dimensional detector array using a single element detector

Patent Strauss, Charlie E [Santa Fe, NM]

Apparatus and method for heterodyne-generated, two-dimensional detector array using a single detector. Synthetic-array heterodyne detection, permits a single-element optical detector to behave as though it were divided into an array of separate heterodyne detector elements. A fifteen-element synthetic array has successfully been experimentally realized on a single-element detector, permitting all of the array elements to be read out continuously and in parallel from one electrical connection. A CO.sub.2 laser and a single-element HgCdTe photodiode are employed. A different heterodyne local oscillator frequency is incident upon the spatially resolvable regions of the detector surface. Thus, different regions are mapped to differentmore »« less

Fuel nozzle having respective arrays of pre-mixing conduits with respective vortex generators

Patent Meadows, Joseph; Beck, Christian

A fuel nozzle including vortex generating features for use in a combustion turbine engine is provided. An array of inner pre-mixing conduits (20) extends between an inlet end (14) and an outlet end (16) of the nozzle. An array of outer pre-mixing conduits (22) may be disposed radially outwardly relative to the inner pre-mixing conduits (20). A fuel-directing tube (24) includes fuel-directing arms (26) structured to direct fuel flow into the outer pre-mixing conduits (22) to be mixed with a flow of air. The fuel-directing arms include a bluff structural arrangement (30) that may be disposed upstream of fuel injectionmore »« less

System for generating two-dimensional masks from a three-dimensional model using topological analysis

Patent Schiek, Richard [Albuquerque, NM]

A method of generating two-dimensional masks from a three-dimensional model comprises providing a three-dimensional model representing a micro-electro-mechanical structure for manufacture and a description of process mask requirements, reducing the three-dimensional model to a topological description of unique cross sections, and selecting candidate masks from the unique cross sections and the cross section topology. The method further can comprise reconciling the candidate masks based on the process mask requirements description to produce two-dimensional process masks.

Swirling structure for mixing two concentric fluid flows at nozzle outlet

Patent Mensink, Daniel L [3578 Gregory La., Lynchburg, VA 24503]

A nozzle device for causing two fluids to mix together. In particular, a spray nozzle comprise two hollow, concentric housings, an inner housing and an outer housing. The inner housing has a channel formed therethrough for a first fluid. Its outer surface cooperates with the interior surface of the outer housing to define the second channel for a second fluid. The outer surface of the inner housing and the inner surface of the outer housing each carry a plurality of vanes that interleave but do not touch, each vane of one housing being between two vanes of the other housing.more »« less
