Title: Furnace heat exchanger tube cleaning system
Inventor: WALDNER CLARENCE
IPC: F28G1/08
Filed: 1997-06-27
Abstract: A furnace heat exchanger tube cleaning apparatus is described. The furnace comprises a combustion chamber for generating heated gases including combustion products, a water jacket containing a liquid to be heated and including heat exchanger tubes passing therethrough and a flue for discharge of the combustion products. In operation, the heated gases including combustion products flow from the combustion chamber along the heat exchanger tubes to the flue.  As the heated gases pass along the heat exchanger tubes, heat from the heated gases is transferred to the liquid in the container, thereby heating the liquid. The efficiency of heat transfer is increased by helical flights arranged to depend downward into the respective heat exchanger tubes from a support structure. Specifically, the flights create turbulence in the flow of the heated gases, thereby improving heat transfer.    However, over time, soot and other combustion products deposit along the heat exchanger tubes, which will decrease heat transfer efficiency. In this arrangement, the heat exchanger tubes can be cleaned by raising and lowering the support structure such that the flights scrape and clean the heat exchanger tubes.

Patent CA-2214414-A1 (CA)
Inventor: GIAMMARUTI ROBERT J
IPC: F28D15/06
Filed: 1997-09-03
Abstract: A heat pipe heat exchanger for regulating the temperature of a wellstream fluid conveyed in a subsea pipeline from a wellhead has an annular reservoir surrounding a section of pipeline adjacent the wellhead. One or more heat pipes extend from the annular reservoir into the seawater. In a heat removal configuration, a working fluid is contained within the annular reservoir. The working fluid boils and is evaporated by heat from the wellstream fluid and forms a vapor, which rises upwardly into and is condensed within the heat pipes, releasing heat into the surrounding seawater. The recondensed working fluid flows back down into the reservoir to repeat the cycle. In a heat providing configuration, the working fluid is contained in the heat pipes, where it is boiled by heat transferred from the surrounding seawater. The resulting vapor rises upwardly into the annular reservoir and the heat is transferred to the cooler wellstream fluids. Other embodiments involve having the one or more heat pipes inserted through the pipeline wall.

Abstract: An apparatus for carrying out a homogeneous nucleic acid amplification and nucleic acid assay on a liquid biological sample comprises a sample well andan optical window element which is received in the sample well. Opposed, spaced-apart surfaces of the optical window element and sample well define a capillary chamber into which a liquid biological sample is drawn by capillary force. By spreading the liquid biological sample into a thin film within the capillary chamber, head space is eliminated, heat transfer to the sample is maximized, and a large optical target is achieved to facilitate the detection step of the assay. The disclosed apparatus is particularly suited for use with homogeneous nucleic acid amplification and fluorescence polarization assays, butcan also be used in connection with other types of biological and chemical processes.
Patent CA-2216046-A1 (CA)
Title: In-line sensor for colloidal and dissolved substances
Inventor: GARVER THEODORE M
IPC: G01N21/53
Filed: 1997-09-18
Abstract: The invention provides a relative measure of the following characters of processwaters or effluents: total dissolved solids, inorganic dissolved solids, organic dissolved solids, colloidal pitch and inorganic colloids. Total dissolved solids (TDS) may be estimated by an empirical mathematical relationship using a combination of UV absorbance and conductivity measurements of microfiltered (filtration <1 micron) water. The relative inorganic and organic portions of the TDS are determined as a mathematical relationship with conductivity and UV. The total amount of colloidal material isdetermined by the absorbance in the visible region in a sample filtered in the 5-100 region. The relative amount of colloidal pitch is determined by measurement of the UV-visible absorbance at two or more temperatures with the pitch concentration being linear with the temperature dependence of the turbidity, absorbance or transmission. A mathematical relationship between the UV measurements at different wavelengths provides an additional measure of the relative portion of pitch colloids. The measurement provides a means for controlling colloidal and dissolved solids in water.

Patent CA-2222556-A1 (CA)
Title: Adduct protection assay
Inventor: NELSON NORMAN C
IPC: G01N33/58
Filed: 1996-05-23
Abstract: The present invention features an adduct protection assay involving the use of a labelled binding partner and a signal altering ligand. The signal altering ligand can preferentially alter the ability of label which is not part of a binding partner, analyte complex to produce a detectable signal, compared to is ability to alter signal produced from label which is part of a binding partner, analyze complex. The presence or amount of analyze can be determined by detecting the signal produced from unaltered label. The adduct protection assay is very versatile. For example, alteration of signal can be carried out under a wide range of conditions (e.g., pH, temperature, and ionic strength), and both label alteration and signal triggering can be carried out at essentially constant temperature to achieve a high degree of sensitivity.

Title: Blasting machine and method
Inventor: LIU LIQING
IPC: F42D1/045
Filed: 1997-12-16
Abstract: Detonator Apparatus, such as a blasting machine detonator, is provided with a miniature transformer having multi-turn primary and secondary coils. The transformer feeds a bridge wire detonator element, and has sufficient impedance to permit impedance matching with a carrier that may be as long as 7500 m. The impedance of the detonator is such that the detonator resists firing when subject to stray currents or commonly present power or communications signals. A blasting machine is provided that is specifically designed to provide a signal having a frequency in the range in which the detonator is sensitive. The blasting machine relies upon semi-conductor switching and timing circuits to control the discharge from a pair of capacitors, rather than upon an output transformer.

Title: Movable manufacturing facility for production of standard size dwellings
Inventor: COHEN ROGER BLAIR
IPC: B28B15/00
Filed: 1996-07-01
Abstract: The movable manufacturing facility (100) brings standard size home building comprehensively within a controlled factory environment. The main structure of the movable manufacturing facility is sufficiently tall to allow assembly and movement of standard size homes within. Multiple independent production lines (P1-P5) are established to each produce portions of the dwelling in the form of subassemblies. Finishes, cabinets, appliances, roofs, paint, etc., are installed in the partially completed dwellings prior to houses leaving the production floor. The movable manufacturing facility allows a standard size home under construction to be advanced via a transport element (T) from one production line to the next until complete. The completed homes are subsequently transported on the transport element over a controlled access roadway to individual sites with pre-constructed foundations specifically designed to accept these standard size dwellings. The standard size house can be relocated from the transport element and placed directly onto the foundation. High capacity hoisting, such as clear span bridge cranes (H1-H3), are the key to material handling and transportation on the production lines in the movable manufacturing facility. A drive through alley large enough to accommodate semi-trucks with loaded trailers may be located within the main structure of the movable manufacturing facility.
