Patent CA-2073648-A1 (CA)
Inventor: LUBINSKI RONALD
IPC: E04G7/26
Filed: 1992-07-10
Abstract: ABSTRACT OF THE DISCLOSURE            A scaffold comprises uprights and transverse tubular braces formed of aluminum. Each upright includes a tubular post extruded with external alignment grooves. Identical aluminum flange assemblies are spaced apart along the post. Each flange assembly includes an extruded sleeve with internal aligning ribs that interlock with the external grooves of the post, and a flange cast with internal ribs that interlock with external alignment grooves extruded with the sleeve. Flange decreases continuously from a central part to its periphery. A set of wedge-receiving openings is formed between the central part and periphery. A brace carries an aluminum connector having upper and lower sections that define a mouth for receiving the flange. An outer part of the mouth mates with inclined upper and lower surfaces of the central part of the flange. An inner part of the mouth remains clear of the flange so that shear forces and bending moments are applied by the brace to the thicker central part of the flange. The connector sections have aligned openings that register with an opening in the flange, and a wedge is inserted that secures the joint.

Title: Rapid amplification and detection of nucleic acids
Inventor: TAVERNARAKIS NECTARIOS
IPC: C12N15/10
Filed: 1992-07-31
Abstract: ABSTRACT         Disclosed herein are methods, primers, probes, and kits for the rapid amplification and detection of nucleic acids.  In a preferred embodiment, a target nucleic acid sequence in a sample is amplified by:  1) adding nucleoside triphosphates, primer pairs comprising two oligonucleotide primers, and a nucleic acid polymerase to the sample; 2) denaturing the target nucleic acid sequence to form separate strands; and 3) maintaining a reaction temperature in a range from 68°C to 80°C and appropriate reaction conditions wherein the following cycle occurs:  the primers hybridize to the target strands, primer extension products are formed, the extension products separate to become templates for the primers, and new extension products are formed.  In an alternative embodiment, the amplification occurs at two different temperature ranges.  Primer extension products are formed in a temperature range from 68°C to 82°C, and the products are separated by raising the temperature to range of 88°C to 96°C. Detection of the amplified sequences occurs by using some biotin-labeled nucleoside triphosphates, which produces nucleotide sequences that are copies of the target sequence and that contain one or more biotin-labeled nucleotides.  The amplified sequences are detected by contacting the sample with immobilized probes and then detecting the presence of the biotin.  A two-stage amplification process is also provided wherein: 1) the probe-target sequence complexes are contacted with a first moiety that binds to biotin; 2) a second moiety, comprising biotin bound to a detectable moiety is added, wherein the biotin in the second moiety binds to the first moiety; and 3) detecting or measuring the detectable moiety.  In a particularly preferred embodiment, primer pairs and a probe are disclosed for use when the target nucleic acid is HIV-1 DNA.

Abstract: : Il sagit de systèmes complets ou "kits" de réparation de fissures de béton et de magonnerie dont toutes les composantes sont inclues dans une (1) boite munie d'une poignée sur le dessus. Ces systèmes complets ou "kits", constituant la présente invention, permettent de réparer par injection les fissures de béton et/ou de maçonnerie avec des résines monocomposantes uniques, soit liquides ou en pâte, qui ne nécessitent pas de catalyseur pour la réaction et/ou le durcissement. Ces résines sont emballées dans des cartouches en plastique simples d'une capacité de 100, 250 ou 300 ml et d'une longueur de 210 mm ou 150 mm. La polymérisation ou le durcissement se fait au contact de l'air ou de l'eau dans un délai de 30 minutes en milieu humide ou en 1 heure en milieu sec. Ces systèmes viennent remplacer l'utilisation de résines bi-composantes actuellement utilisées pour de telles réparations afin de permettre à tout propriétaire de maison, de building ou de tout autre structure de réaliser lui-même les dites réparations sans avoir à faire appel à un professionnel de la construction. Ces systèmes réunissent quatre (4) items différents servant à la préparation et à l'injection de fissures fines ou larges. L'utilisateur doit simplement utiliser un "fusil" à calfeutrage "standard" qui dans la plupart des cas, se retrouve dans son coffre à outil. Ces systèmes sont conçus pour une fissure d'une certaine longueur par une certaine largeur. En cas de besoin d'un des items en plus grande quantité, il est possible d'acheter chaque composante à l'unité dans des emballages de type "blister pak" sans être obligé de reprendre un système ou "kit" complet.

Abstract: A self-packaging safety syringe set (2) uses a unitary molded set of enclo-sure units (8, 104) sized for housing conventional cartridge-needle units (12) there-in. The set of enclosure units are connected to one another by frangible connec-tions (64, 66, 130, 138). The cartridge-needle unit has a hollow barrel (14) with a needle assembly (24) mounted to one end and a piston (16) mounted therein.  Each enclosure unit includes a body section (38, 106), a stem section (44, 108) frangibly connected to one end of the body section, and an end cap (52, 110) connected to the other end of the body section. The frangible connection (48, I 18) is broken to remove the stem section to expose the needle (26) for use. The removed stem sec-tion is used to drive the piston within the barrel. After use, the barrel is pulled back through the body section so that the needle is completely housed within the body section.
