Title: Reagent and method for detecting a cryptosporidium parvum sporozoite antigen
Inventor: CALL JEFFREY L
IPC: C07K16/20
Filed: 1999-12-07
Abstract: A reagent and method for the specific and highly sensitive detection of C.  parvum in which the reagent is an antibody for a soluble C. parvum sporozoite antigen and the method is an immunoassay in which the antibody is used to detect or quantify C. parvum sporozoite antigen in a sample. The sample is treated to cause excystation of C. parvum oocysts, thereby releasing a C.  parvum sporozoite antigen, and combined with antibodies specific for the sporozoite antigen under conditions to form an antibody-antigen complex.  Detection of the complex indicates the presence of C. parvum in the sample.  The assay allows recognition and detection of C. parvum in turbid samples, and due to a lack of crossreactivity with other Cryptosporidium species, is specific for C. parvum contamination or infection. The assay is highly sensitive, allowing for the detection of less than 100 oocysts per milliliter of sample.

Title: Integrally asymmetrical polyolefin membrane
Inventor: WECHS FRIEDBERT
IPC: B01D69/08
Filed: 2000-01-19
Abstract: Process for producing integrally asymmetrical hydrophobic polyolefinic membranes with a separation layer, in particular for gas exchange, via thermally induced liquid-liquid phase separation. A solution of at least one polyolefin in a solvent system con-sisting of a compound A and a compound B is extruded to form a shaped object. Compound A is a strong solvent and compound B a weak non-solvent for the poly-mer. After leaving the die, the shaped object is cooled using a solid or liquid cooling medium, which does not dissolve the polymer and does not react chemically with it, until the phase separation and solidification of the high-polymer-content phase take place. The integrally asymmetrical membrane producible in this manner has a poros-ity of greater than 30% to 75% by volume, a sponge-like, open-pored, microporous support layer without macrovoids and on average isotropic pores, a separation layer on at least one of its surfaces with pores <100 nm, if any, and a gas separation fac-tor a(CO2/N2) of at least 1. The membrane is preferably used for blood oxygenation.

Patent CA-2369227-A1 (CA)
Title: Digital transmitter system and method
Inventor: GARCERAN JULIO ANTONIO
IPC: H03C1/00
Filed: 2002-01-23
Abstract: A digital transmitter converts a digital signal into analog form with a digital to analog converter (DAC) and uses an analog signal image produced from the DAC  to provide an analog signal at a transmission frequency and/or uses a projected analog signal image to produce analog signals for transmission. Rather than removing analog signal images with a low pass filter at the output of the DAC and/or using analog signal images and analog mixers for frequency conversion, the digital transmitter uses the analog signal images from the DAC to produce the analog signals at the desired frequency/frequencies. By setting and/or adjusting the conversion rate for the DAC and/or the digital signal frequency/frequencies; the analog signal images produced from the DAC can be positioned in the desired frequency band(s). For example, the digital transmitter can position the digital signals within non-overlapping portions of a conversion bandwidth defined as one-half the conversion rate for the DAC. When the digital signals are converted into analog form, the DAC produces analog signal images periodically repeated at multiples of one-half the conversion rate such that analog signal images are produced at the appropriate frequency band(s) for amplification and transmission.

Inventor: HARGREAVES THOMAS E
IPC: B29C53/08
Filed: 2002-02-08
Abstract: A machine and method for forming a spring coil (12) in a length of hollow, cylindrical thermoplastic tubing(10) comprises clamping the ends of a predetermined length of cylindrical thermoplastic tubing between first (90) and second (54) opposing spaced clamping members. In the machine, these clamping members include aligned first and second sections of a mandrel (28 and 30). These first and second clamping members then are rotated relative to one another (via 76, 78) by a predetermined amount selected to be slightly in excess of 360°, while the mandrels are simultaneously moved toward one another (via 24 and 26), to shorten the distance between the ends of the length of tubing, while the coil is formed. At the end of this relative rotation, the mandrel sections engage one another (at 29, 31). The clamped tube (l0), with the coil (12) now formed around the mandrels, is rotated (via 94, 96) and simultaneously heated (via 110) to the thermosetting temperature of the tubing. After a sufficient time to establish thermosetting of the coil, the heat is removed.        Rotation continues while the tube is cooled. Following the cooling cycle, the apparatus operates to release the tubing, with the formed coil in it, from the machine.

Title: Methods for monitoring eukaryotic cell integrity, growth and/or division
Inventor: PRICE RACHEL LOUISE
IPC: G01N33/15
Filed: 2000-05-09
Abstract: A method for detecting the presence of a lysed eukaryotic cell in a sample, said method comprising: (i) adding adenosine diphosphate (ADP) to said sample under conditions which allows the conversion of ADP to adenosine triphosphate (ATP) by cellular adenylate kinase, (ii) detecting ATP in said sample and relating that to the presence of adenylate kinase and thus to the presence of lysed cells. The method is useful in detecting the cell lysis, for example when screening for drugs which are required to cause lysis, for example for use in tumour therapy. However, in addition, cells may, in a preliminary step, be lysed and the contents quantitated in order to establish for example the health of condition of the cells or to detect the presence of cells in sample such as milk or urine, for diagnostic purposes.

Title: Systeme a bride et bague coniques de serrage et de desserrage d'outils de forage
Inventor: DOANE JAMES CHRISTOPHER
IPC: E21B33/129
Filed: 2002-03-01
Abstract: Un ancrage d'outil de puits à desserrage de manière sélective comporte une cage tubulaire englobant les sabots porte-dents et un manchon de positionnement tubulaire assemblé de manière coulissante sur un mandrin tubulaire. La cage englobant les sabots porte-dents confine une pluralité de sabots porte-dents indépendants. Le manchon de positionnement tubulaire présente une surface de glissement conique qui est mise en prise de manière lâche avec la cage englobant les sabots porte-dents par une pluralité de doigts de bride s'étendant à partir de la surface de glissement conique dans une mise en prise avec les ergots dans la cage englobant les sabots porte-dents. Les doigts de bride sont fixés aux ergots au cours du positionnement dans le puits par des attaches de cisaillement étalonnées. Les surfaces de glissement sur la pluralité de sabots porte-dents sont alignées avec la surface de glissement conique pour effectuer un déplacement radial des sabots porte-dents par une translation axiale du manchon de positionnement par rapport à la cage englobant les sabots porte-dents. Toutefois, aucune translation axiale ne peut se produire avant qu'une force de compression axiale suffisante entre la cage englobant les sabots porte-dents et le manchon de positionnement ne soit exercée pour couper les attaches étalonnées. Pour procéder à la libération sélective à partir du puits de forage, le manchon de positionnement présente une bague de verrouillage de corps assemblé sur l'alésage interne du manchon de positionnement. La bague de verrouillage présente un filet en dents de scie qui se met en prise avec le filet externe sur le mandrin à une position sélectionnée le long du mandrin. Le déplacement du mandrin pour mettre en prise le filet de ce dernier avec le filet de la bague de verrouillage tire la surface de glissement conique hors de la surface de glissement du sabot porte-dents, ce qui permet de libérer les dents d'une mise en prise profonde dans le mur du puits.
