Method And Apparatus For Providing And Using Rf Generated Plasma For Particle Charging In Electrostatic Precipitation

View page
US Patent:
44721749, Sep 18, 1984
Filed:
Apr 25, 1983
Appl. No.:
6/488416
Inventors:
Raymond L. Chuan - Huntington Beach CA
International Classification:
B03C 312
US Classification:
55 5
Abstract:
Method and apparatus for employing a plasma produced in a radio-frequency discharge to enhance electrostatic precipitation. The plasma is generated in an auxiliary gaseous stream, and the plasma is introduced into a primary fluid stream flowing toward or in an electrostatic precipitation zone. The plasma causes ionization of the auxiliary gaseous stream, and the ionized gaseous stream charges the particles in the primary fluid stream. The primary fluid stream in which the particles are entrained flows in a primary duct toward an electrostatic precipitator containing the precipitation zone. A plasma generator generates plasma in the auxiliary gaseous stream to cause ionization thereof; and a secondary duct conducts the plasma into the primary stream for charging particles in the primary fluid stream. The charged particles then flow in the primary fluid stream into the precipitator.

Pollution Monitor With Self-Contained Calibration And Cell-Block Therefor

View page
US Patent:
39448347, Mar 16, 1976
Filed:
Oct 4, 1974
Appl. No.:
5/512338
Inventors:
Raymond L. Chuan - Altadena CA
Parameswar Mahadevan - Cerritos CA
Daryl J. Bergquist - Huntington Beach CA
Assignee:
Celesco Industries Inc. - Costa Mesa CA
International Classification:
G01D 1800
G01J 142
G01N 2138
US Classification:
250372
Abstract:
The embodiment of the pollution monitor described in the specification uses the principle of ultraviolet-induced fluorescence to detect and measure gaseous pollution in air, smokestack exhaust and other fluids. Improved calibration or standardization is effected by the use of one or more calibration cells in which a non-gaseous material simulates the fluorescence of the gaseous species under investigation, by scattering the incident ultraviolet light into a spectral region similar to that of the fluorescence of the gaseous species. Examples of suitable materials have been found to be aluminum, gold, platinum and molybdenum, all of which scatter light in the appropriate spectral region at a level which stays substantially constant with time. In the preferred embodiment, the sample cell and the calibration cells are all formed in a single cell block by drilling holes into solid bar material which holes function as the individual cell cavities. The sample cell has ports for the flow of sample gas therethrough, while in each of the calibration cells, the metallic material is mounted to intercept and scatter the incident ultraviolet light energy.

Apparatus And Methods For Detecting An Incipient Fire Condition

View page
US Patent:
42235596, Sep 23, 1980
Filed:
May 9, 1978
Appl. No.:
5/904229
Inventors:
Raymond L. Chuan - Los Angeles CA
Houston D. Chen - Santa Ana CA
Assignee:
Brunswick Corporation - Skokie IL
International Classification:
G01N 1502
US Classification:
73432PS
Abstract:
Apparatus and methods for detecting an incipient fire condition based on a shift in the size distribution of particles generated by a developing incipient fire condition. Particulate mass concentrations of at least two different particulate sizes are monitored and the ratio of the outputs from the sensing devices is processed as an indication of an incipient fire condition. In another form of the invention, the rate of change of the ratio of the outputs from the monitoring devices is processed as an indication of an incipient fire condition.

Gas Detection By Ion Mobility Segregation

View page
US Patent:
47243945, Feb 9, 1988
Filed:
Oct 11, 1985
Appl. No.:
6/786666
Inventors:
Scott R. Langer - Westminster CA
William D. Bowers - Newport Beach CA
Michael F. Steele - Fountain Valley CA
Raymond L. Chuan - Huntington Beach CA
Assignee:
Brunswick Corporation - Skokie IL
International Classification:
G01N 2762
US Classification:
324464
Abstract:
A device for gas detection through ion mobility segregation by mobility ranges includes a flow tube through which a sample of atmospheric air with possible contaminant gases flow. Ions formed of gases in the air and the possible contaminant gases are segregated by ion mobility range in either a first, second or subsequent electric field positioned along the flow tube. The ions are collected on an anode or cathode of each electric field. The ions of the gases striking an anode or cathode by charge transfer induce a detection current, the measure of which indicates the presence of gases of interest. A method for detecting a gas by ion mobility segregation is also described.

Projector Slide Orientation Rectification System

View page
US Patent:
52144607, May 25, 1993
Filed:
Nov 4, 1991
Appl. No.:
7/787653
Inventors:
Raymond L. Chuan - Hanalei HI
International Classification:
G03B 2308
US Classification:
353122
Abstract:
A projector slide has eight possible orientations, only one of which is the correct one to project a properly oriented image. For an automatic orientator to work there must be a simple way to recognize any one of the eight orientations and decide how to place the slide in the correct orientation. A method and device is described here which accomplishes this task.

Underwater Sound Attenuator

View page
US Patent:
51385880, Aug 11, 1992
Filed:
Apr 15, 1991
Appl. No.:
7/684512
Inventors:
Raymond L. Chuan - Huntington Beach CA
Houston Chen - Santa Ana CA
Assignee:
Brunswick Corporation - Skokie IL
International Classification:
H04R 1700
US Classification:
367176
Abstract:
An apparatus for preventing the transmission of sound in an underwater medium. A resilient housing encloses at least two voids. A first void contains a compliant tube consisting of two T-shaped support structures, each T-shaped support structure supporting a free-bending span designed to resonate at a predetermined frequency. A second void contains a viscous liquid in which metal fibers are suspended. The resilient housing may be surrounded by a rigid cover material which may include means for fastening the apparatus to a surface. The viscous liquid dissipates sound. The compliant tube attenuates the sound waves and decreases the velocity of the sound waves, consequently decreasing the wavelength of the waves.

High Sensitivity Real-Time Nvr Monitor

View page
US Patent:
56612265, Aug 26, 1997
Filed:
Nov 9, 1995
Appl. No.:
8/554893
Inventors:
William D. Bowers - Newport Beach CA
Raymond L. Chuan - Hanalei HI
Assignee:
Femtometrics - Irvine CA
International Classification:
G01N 2902
US Classification:
73 2401
Abstract:
A real time non-volatile residue (NVR) monitor, which utilizes surface acoustic wave (SAW) resonators to detect molecular contamination in a given environment. The SAW resonators operate at a resonant frequency of approximately 200 MHz-2,000 MHz which enables the NVR monitor to detect molecular contamination on the order of 10. sup. -11 g-cm. sup. -2 to 10. sup. -13 g-cm. sup. 2. The NVR monitor utilizes active temperature control of (SAW) resonators to achieve a stable resonant frequency. The temperature control system of the NVR monitor is able to directly heat and cool the SAW resonators utilizing a thermoelectric element to maintain the resonators at a present temperature independent of the environmental conditions. In order to enable the direct heating and cooling of the SAW resonators, the SAW resonators are operatively mounted to a heat sink. In one embodiment, the heat sink is located in between the SAW resonators and an electronic circuit board which contains at least a portion of the SAW control electronics.

Incipient Fire Detector

View page
US Patent:
39538443, Apr 27, 1976
Filed:
Apr 11, 1973
Appl. No.:
5/350091
Inventors:
Laurence Gibson Barr - Mission Viejo CA
Raymond Lu-po Chuan - Altadena CA
James Fredrick Harkee - Glendora CA
Assignee:
Celesco Industries Inc. - Costa Mesa CA
International Classification:
G08B 1710
US Classification:
340237S
Abstract:
The incipient fire detector employs a particulate monitor for detecting particulates in the atmosphere. During an incipient fire condition, prior to ignition, a large mass of particulates less than 5 microns in size is generated by the combustible material which increases the concentration of such particulates in the atmosphere. The detector samples and responds to the rate of increase of such particulates to provide an alarm when such rate exceeds a predetermined rate indicative of a hazardous condition. The particle collector employed in the incipient fire detector is specially designed to collect particulates less than five microns in size and reject those above this size.
