Abstract: A liquid to gas converter to convert liquids (1) to gas (2) that can include a liquid pressurization element (3), a liquid preheating element (5), and a nozzle (10) to disperse liquids into energy (7) generated by an energy source (8). The gas to liquid converter can be located inside an enclosure (17) and substances dissolved in the liquid can accumulate as solids (13) on deposition surface (12) of the enclosure as the liquid (1) converts to gas Cis (2). Condensation of a portion of the gas (2) generated can be combined with the solids (13) for continuous removal of such solids (13) from the enclosure (17). A gas expansion compensator can generate a pressure gradient (24) to move the volume of gas generated from the liquid from the enclosure (17).

Abstract: An improved system of igniting a plasma using a rapid voltage rise and thus causing ions that may be pre-existing to create secondary electron emission or the like is provided. In one embodiment, the voltage rise can be timed to be comparable to the transit time of the electrons across the plasma. It can also be arranged to achieve a voltage rise in less than 1000 microseconds, to result in a transition time that is less than one hundred times the transit time, to maximize the emission of secondary electrons, or even to merely result in collision energies ranging from 5 to 500 electron volts. The transition time can be controlled through an ignition control that may be programmable, may involve charging output storage devices, or may involve delayed switching to supply the increased voltage to the plasma after the storage elements have been more fully charged.

Abstract: Enclosures having adjustable clean gas flow environments and methods of enclosed pressure differential distribution technology. Specifically, clean gas flow enclosures, which provide for the isolation of materials from airborne micro-particulate contamination. An embodiment of the invention utilizes a small footprint, modular, selectable, clean-gas flow environment for handling and isolating materials. The environment can be a clean room class environment by providing filtered gas from a gas flow generator (12) through a gas filter (13) to a filtered gas flow space (20). An embodiment of the invention provides a first plenum (23) and a second plenum (26) so that both a horizontal filtered gas flow and vertical filtered gas flow may be used separately or in combination within the same filtered gas flow space (20).

Abstract: A resilient retention method which retains two assemblies axially through the use of a flange and lip arrangement and simultaneously retains those assemblies rotationally through either a radial detent or a snap spring are shown in variations. The designs are especially configured for molding so that each might utilize the material properties available and yet be economically manufactured. Further, user features including both visual and potentially audible indications of full assembly are incorporated into the designs and automatically achieved. Shut-off valve designs are shown which are automatically delayed in opening until some axial retention occurs to minimize any blow-off or other undesirable operational events. Swivel features may be incorporated when the application requires.

Abstract: This invention is a specific set of oligonucleotide Polymerase chain reaction (PCR) primers [5′-GTGATCCGGCATATAGCTGAGA-3′ (SEQ ID No. 1) and 5′-TGGTCGCTGATCAGGATGGAA-3′ (SEQ ID No. 2)] for specific polymerase chain reaction (PCR) amplification of a region of the bovine male-specific chromosome sequence.

Abstract: An improved nozzle system for a flow cytometer and accompanying methods have been invented for a high efficiency orientation and sorting process of a flat sample and dedicates items such as equine or bovine sperm cells. This improved nozzle system comprises a nozzle with a novel interior surface geometry that can both gently accelerate the cells and can include an elliptical-like, single torsional interior surface element within the nozzle, i.e., a single torsional orientation nozzle. The elliptical-like, single torsional interior surface element may have a laminar flow surface and may produce the simplest flow path for applying minimal forces which act in either an accelerative nature or orienting hydrodynamic forces, namely, the single torsional orientation forces, to orient a flat sample such as animal sperm cells into a proper direction for an analyzing and efficiently sorting process in clinical use, for research and for the animal insemination industry.

Abstract: A flow cytometer (20) capable of utilizing an imaging system including a sensor (88) to determine various properties of the flow cytometer (20). Importantly, the imaging allows for determination of a drop delay time (154). Other characteristics that can be determined include at least the width of the stream, pressure of the stream, effect of charged droplets on other droplets (44), trajectory of the stream, resonant frequency, wavelengths, change in position of droplet break-off point (150), and others. An automatic warning system (180) can be used to alert an operator of an anomaly during setup or during normal operation. Furthermore, a mechanical interrupter can be used to shield a sort result from contamination by an incorrectly functioning stream. The cytometer (20) also allows for the disablement of the sort, particularly the charging and deflection systems. In addition, a more accurate system for detecting the speed of the stream can be used.

Abstract: Method and apparatus are disclosed for providing a constant voltage, high frequency sinusoidal output across a varying load, using either a single or multiple switch topology operating at constant frequency while maintaining high efficiency over the entire load range. This embodiment is especially suited to applications which require the sinusoidal voltage be held very close to a desired value in the presence of rapid changes in the conductance of the load, even in the sub-microsecond time domain as is common in computer applications and the like and in powering electronics equipment, especially a distributed system and especially a system wherein low voltage at high current is required.

Abstract: The biosensor involves a specially designed surface which can be optically coupled to a Surface Plasmon Resonance spectrometer. The key components of the biosensor are a bimetallic layer, a self assembled monolayer of chemicals and a layer of biomolecules such as special antibodies. The innovative bimetallic layer combines the sensitivity of silver metal and durability of gold and thus make it an ideal biosensor layer not only for a low volatility gas phase detection but also for a liquid phase detection. The successful application of the biosensor in high explosive substance detection proves that the biosensor is a sensitive and highly specific device for security and anti-terrorism applications, when it is combined with a Surface Plasmon Resonance Spectroscope.

Abstract: An axially-rotated valve permitting increased flow rates and lower pressure drop is disclosed using an axial eccentric split venturi with two portions where at least one portion is rotatable with respect to the other portion. A cross section of the eccentric split venturi may be non-axisymmetric such as a semicircular cross section which may assist in both throttling capabilities and in maximum flow capacity. Applications are disclosed for freeze resistant axially-rotated valves which may be fully-opened and fully-closed in one-half of a complete rotation. An internal wide radius elbow connected to a rotatable portion of the eccentric venturi may assist in directing flow with lower friction losses. A valve actuator may actuate in an axial manner located outside of the axial flow path. A seat may be used between the two portions that may include a peripheral and diametrical seal in the same plane.

Abstract: Techniques and devices for detecting and analyzing controlled substances and the like are discussed including highly reactive sensor molecules which are coated on a spectroscopic sample surface (4) and which may chemically react with a given analyte to form a covalently bonded adduct with spectral characteristics unique to the new adduct. The techniques provide the basis of a detection system with high sensitivity and high specificity in which the surface can even be washed to remove interfering or nonreactive compounds. The sensor molecules which comprise the coating (8) may have three major components: a central molecular scaffold (“CMS”), a “tether” terminated by a surface attachment group “SAG,” and a reactive functional group “RFG” which may be highly reactive towards certain classes of molecules.

Abstract: An enhanced DC plasma processing system which acts to immediately stop current from flowing through the plasma allows a variety of alternative embodiments for varying applications. In one embodiment, a tapped inductor is switched to ground to achieve substantial voltage reversal of about 10% upon detection of an arc condition through voltage and/or rate of voltage change techniques. This reversal of voltage is maintained long enough to allow restoration of uniform charge density within the plasma prior to restoration of the initial driving condition. A technique for preventing arc discharges involving periodically applying a reverse voltage is effected through a timer system in the power supply.
