Patent CA-2190072-A1 (CA)
Title: Fluorescence Polarization Detection of Nucleic Acid Amplification
Inventor: LINN CARL PRESTON
IPC: C12Q1/68
Filed: 1996-11-12
Abstract: Fluorescence polarization methods for detection of nucleic acid amplification atthermophilic temperatures employ a fluorescently labeled oligonucleotide signal primer which is converted from single- to double-stranded form in a target amplification-dependent manner. This conformational change is accompanied by an increase in fluorescence polarization values. The decrease in FP typically observed for the duplex at elevated temperatures is overcome by double-stranded DNA binding proteins which are believed to stabilize the double-stranded structure by reducing the single-strandedness normally associated with higher temperatures. The inventive methods provide a closed, homogeneous system for amplification and detection of amplification in real-time or at an endpoint.

Patent CA-2191926-A1 (CA)
Inventor: KORINEK CHRIS W
IPC: B25B23/14
Filed: 1996-12-03
Abstract: Ends of several electrical wires are joined by a connector (10) which is twisted onto the wire to a predefined torque level by using a unique tool socket (32).  The connector (10) has a body (12) with closed end (15) and an open end (14) for receiving the electrical wires.  At least a portion of the hollow body (12) has an equilateral polygonal cross section shape formed by side surfaces (16) which meet at corner sections (38).  The tool socket (32) includes a coupling (34) through which torque is applied and has an aperture (36) for receiving the connector (10).  The aperture (36) has a cross sectional shape such that the tool socket (32) engages only the connector corner sections (38) and a space exists between the connector side surfaces (16) and the socket (32).  That engagement concentrates torque applied by the tool socket (32) to the connector (10) which causes the corner sections (38) to round upon application of more than the predefined torque level, thus preventing excessive torque from being applied to the connector and the wires.

Title: Method and apparatus for delivering a cased glass stream
Inventor: SCOTT GARRETT L
IPC: C03B7/088
Filed: 1997-09-08
Abstract: Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a spout for receiving core glass from a first source and delivering such glass through a first orifice. A second orifice is vertically spaced beneath and aligned with the first orifice, and is surrounded by an annular chamber that communicates with the second orifice through the gap between the first and second orifices. A tube delivers casing glass from a second source to the annular chamber in such a way that glass flows by gravity from the first and second sources through the orifices to form the cased glass stream. The core glass delivery spout includes a reservoir for receiving and holding the core glass, and having at least one lower opening of a first diameter. An orifice ring is positioned beneath the reservoir, and has at least one opening of second diameter less than the first diameter aligned with the first opening and forming the first orifice. A  collar of uniform inside diameter equal to the first diameter extends from the first opening to the orifice ring, and thereby spaces the reservoir from the orifice ring so as to increase hydrostatic head pressure on glass flowing from the reservoir through the first orifice. The core glass reservoir is surrounded by a metal casing, and the casing glass delivery tube extends through a notch in the sidewall of the core glass casing. An air-cooled liner controls heat transfer from the casing glass delivery tube to the core glass reservoir.
Patent CA-2215421-A1 (CA)
Inventor: MYERS RONALD DAMIAN
IPC: C10G45/02
Filed: 1997-09-26
Abstract: The invention relates to an integrated, continuous process for the removal of organically bound sulfur (e.g., mercaptans, sulfides and thiophenes) comprising the steps of contacting a heavy oil, sodium hydroxide, hydrogen and water at a temperature of from about 380°C to 450°C to partially desulfurize the heavy oil and to form sodium sulfide, contacting said sodium sulfide via steam stripping to convert the sodium sulfide to sodium hydroxide and the sulfur recovered as hydrogen sulfide. The sodium hydroxide is recirculated for reuse. The partially desulfurized, dewatered heavy oil is treated with sodium metal under desulfurizing conditions, typically at a temperature of from about 340°C to about 450°C, under a hydrogen pressure of at least about 50 psi to essentially desulfurize the oil, and form sodium sulfide. Optionally, the sodium salt generated can be regenerated to sodium metal using regeneration technology. The process advantageously produces essentially sulfur-free product oils having reduced nitrogen, oxygen and metals contents and reduced viscosity, density, molecular weight and heavy ends.

Title: Method for fracturing a formation to control sand production
Inventor: MONTGOMERY CARL THOMAS
IPC: E21B49/00
Filed: 1995-04-13
Abstract: A method for determining the minimum length for a fracture in a fluid-producing formation to control the production of sand therefrom wherein a plurality of critical drawdown pressures are calculated from known formation data which correspond to a plurality of different, estimated respective fracture lengths. Once the critical drawdown pressures for the reservoir are correlated with their corresponding fracture lengths, a critical drawdown curve for that particular reservoir is established. Additional sets of curves are generated from known data which when overlaid with the critical drawdown pressure curve allows a minimum length of fracture to be selected which will produce the formation at a given rate at a prescribed drawdown pressure without producing any substantial amounts of sand from the formation.
Patent CA-2218965-A1 (CA)
Inventor: WEBER WILLIAM C
IPC: B65H35/02
Filed: 1997-10-17
Abstract: A method and apparatus is disclosed for producing high page count signatures for printed publications. Signatures with a 96 page count and 128 page count areillustrated and described herein. In either case, the signature is constructed of four sheets of printed sheet materials which are preferably continuous webs of sheet material that are fed to a folding and cutting apparatus. The four sheets or webs are folded in half along a main longitudinal fold line extending in the direction in which the web travels. Preferably, the webs are perforated along the main longitudinal fold line prior to being folded. The webs, after being folded in half, are perforated to create a longitudinally extending hinge. Also, the webs are preferably perforated to create cross fold lines. In the case of the 96 page count signature, the folded webs are divided into thirds by the cross fold lines. The folded webs of the 128 page count signature are divided into fourths by the cross fold lines. The webs are then cut into sections which are folded along the fold lines to form the individual signatures.
