Patent CA-2214488-A1 (CA)
Title: Determination of cpsa
Inventor: ZHOU ZEGI
IPC: G01N33/577
Filed: 1997-09-03
Abstract: A method for determining the complexed forms of immunologically determinable prostate specific antigen (cPSA) in a blood sample, e.g., by two- site immunometric assays, in which the blood sample is treated to render free PSA (fPSA) immunologically nondetectable. A particularly preferred immunometric assay method employs three anti-PSA antibodies: an antibody that binds to both cPSA and fPSA (anti-tPSA), a second anti-tPSA antibody which is characterized by the unique property that binding to fPSA is blocked by binding of fPSA-specific antibodies, and a third antibody which is a fPSA-specific antibody. Thus, binding of the fPSA-specific antibody to PSA in the sample allows only cPSA to be measured in the immunometric assay. Measurement of cPSA blood levels has been found to provide a method for aiding in the diagnosis and monitoring of prostate cancer that is highly sensitive and specific, and eliminates the need for a significant number of patients to undergo unnecessary prostate biopsy.

Title: Reduction of solid defects in glass due to refractory corrosion in a float glass operation
Inventor: TSAI YIH-WAN
IPC: C03B5/167
Filed: 1997-10-24
Abstract: The present invention provides an apparatus and method for reducing the occurrences of solid defects in float glass due to corrosion of refractory in a glass melting and refining furnace. In making flat glass by the float process, batch materials are fed into a melting and refining furnace and heated to form molten glass. The molten glass passes through the melting section and into a refining section of the furnace where the glass is gradually cooled and conditioned prior to delivering the glass to a forming chamber where the molten glass is floated upon molten metal and formed into a continuous sheet of glass. During the melting operation, alkali vapors from the molten glass accumulate within a downstream portion of the melting section. These vapors attack and corrode those portions of the melting section of the furnace which are constructed from silica refractory. The products of the corrosion are deposited in the molten glass resulting in solid defects. In the present invention, a nonreactive gas is directed into the downstream portion of the melting section at a temperature no greater than that of the molten glass within the melting section and at a gas volume sufficient to reduce the amount of alkali vapors in the downstream portion of the melting section. As a result, the corrosion of the silica refractory is reduced and the total occurrences of solid defects in the glass due to refractory corrosion is reduced. In on embodiment of the invention, the gas is the combustion products from burners that are positioned in the downstream portion of the melting section of the furnace.

Inventor: SALKOWSKI THEODORE J
IPC: A23G9/22
Filed: 1997-10-27
Abstract: An air/liquid mix regulator is disclosed for use in a frozen confectionary dessert dispensing machine. The mix regulator regulates the amount of liquid and air entering the freezing chamber of the frozen dessert machine. The regulator has a single aerator tube having both an air inlet passage and a liquid inlet passage which are least partially divided. The aerator tube has different liquid inlet openings at each end so that it is invertible and usable with differing liquid viscosities. The aerator tube is engageable with a base section of the regulator and has a check valve therein to prevent the backflow of aerated mix into the storage chamber to prevent frothing and foaming in the storage hopper. The single check valve is located in an area of the base section that takes advantage of the relatively warmer liquid in the storage hopper to prevent freezing and sticking of the check valve. The regulator has a twist-lock feature to prevent self-ejection when the check valve is closed and a pressure differential occurs between the freezing chamber and the storage hopper. The regulator provides self priming, prevents freeze-ups, disassembles easily for cleaning, is able to feed a wide viscosity range of mix, and maintains a stable desired overrun for producing a dispensed product with consistent, desired serveability, while increasing profits of the vendor.
