Inventor: LEE MARTIN ALAN
IPC: C12Q1/68
Filed: 2001-03-06
Abstract: A method of analysing the length of a particular region within a nucleic acid, said method comprising a) subjecting a sample of said nucleic acid to a plurality of amplification reactions in which said region is amplified, wherein the time of the extension phase in each of said reactions is varied;  b) monitoring the progress of said amplification reactions; c) determining the minimum time during which extension phase of the amplification is completed within each reaction mixture and relating that to the length of the sequence undergoing extension. The method, combined with melting point analysis will allow percentage GC content of a sequence to be determined. Length analysis of this type can be used in diagnosis or analysis as well as in recombinant DNA  technology to check for the presence of concatamers, and in taxonomic classification or forensics. Apparatus for use in the method is also described and claimed.

Prior to stretch aperturing, the web has a peak elongation of at least 100 percent and is characterized by having a plurality of discrete, spaced-apart, frangible bond sites of polymer bonding the fibers to form a coherent extensible nonwoven web. The frangible bond sites are structured and arranged to readily rupture when subjected to tensile stress to form discrete, spaced-apart apertures in the nonwoven fabric. Aperturing the web tends to produce remnants of the bond site polymer at the edges of the apertures. The web has a total energy absorption in at least one of the machine direction or the cross-machine direction of at least 50 gcm/cm2.

Title: Pentagonal helical antenna array
Inventor: STRICKLAND PETER C
IPC: H01Q21/06
Filed: 2002-10-17
Abstract: A pentagonal antenna array having a high aperture efficiency and a suitably high overall gain and low antenna noise temperature. The high aperture efficiency of this antenna system provides an overall system capacity suitable for broadband communication services. The antenna array consists of five antenna elements each located at a separate vertex of a pentagon.      The antenna elements are helical antennas to provide a narrow antenna beam width. The antenna array itself is supported on a base platter which may be steered to point at a satellite using conventional gimbal ring apparatus.      The base platter is a planar reflector to reflect the antenna element radiation in the rear direction and thereby reduce the antenna backlobe levels. The input power and the signal. transmitted are fed through a phasing/combining network. The phasing/combining network appropriately divides the signal and the input power and phases the signal, prior to feeding the signal to each of the five antenna elements.

Title: A method and an apparatus for producing a gaseous medium
Inventor: HALLSTADIUS HANS
IPC: G01N21/33
Filed: 2001-04-20
Abstract: The invention relates to a method and a system for producing a gaseous medium containing a sterilisation agent and for monitoring and regulating the concentration and quality of the gaseous medium. The method preferably includes concentration determination of a substance or agent in a sample of the gaseous medium in the presence of disruptive matter by means of light absorption, as well as an apparatus therefor. By measuring the light absorbency at two different wavelengths, it is possible to detect and compensate for the effect of disruptive matter such as dust particles, dirt and bubbles (aerosols). By also measuring the intensity of light emitted from the light source which has not yet passed through the measurement sample, simultaneously with the measurements of the absorbency of light allowed through the sample, at each measured wavelength, the actual concentration can be determined with improved accuracy. The method and the system are applied for the sterilisation of packaging materials, packaging containers and packing or filling machines within the food packing industry.

Patent CA-2420212-A1 (CA)
Title: Light-distribution control device
Inventor: OYAMA NOBUO
IPC: F21V11/02
Filed: 2001-09-07
Abstract: A light distribution control device comprising a generally plane- or film- shaped optical diffusion structure having an optical transmittance or reflectivity and including a multiplicity of ridges arrayed in parallel with  each other on its one face. Each ridge forms a part of a circle generally in  a section normal to the longitudinal direction thereof, and is made so smooth on its surface as not to cause a drastic irregular diffusion of light. In the diffraction grating effect to be caused by the parallel array of the multipl e ridges, the ratio of the amount of diffractive light to the amount of incide nt light is adjusted by selecting the angle of circumference and the maximum diameter of the section of each ridge. Where an optical beam is introduced t o the face of the optical diffusion structure, the projection of the diffusion  distribution on the plane normal to both the longitudinal direction of the ridges and the face of the structure is generally symmetric with respect to the axis of the normal line at the incident point irrespective of the incidence angle of the optical beam.

Title: Urocortine iii et certaines de ses utilisations
Inventor: PERRIN MARILYN H
IPC: C07K14/00
Filed: 2002-03-15
Abstract: La présente invention découle d'une recherche dans la base de données publique du génome humain, laquelle recherche a permis d'identifier une étiquette de séquence exprimée ou "EST" (Expressed Sequence Tag) humaine correspondant au numéro d'accession GenBank AW293249, et présentant une homologie élevée avec des séquences connues d'urocortine du poisson globe. La séquence a été amplifiée dans toute sa longueur à partir de l'ADN génomique humain et séquencée. Les comparaisons d'homologie de séquences de la séquence de l'invention avec les urocortines I et II humaines a révélé que la séquence a codé une urocortine humaine nouvelle, qui a été appelée urocortine III (UcnIII). Alors que l'urocortine III n'a pas d'affinité élevée pour le CRF-R1 ni pour le CRF-R2, l'affinité pour le CRF-R2 est supérieure que l'affinité pour le CRF-R1. L'urocortine III est capable de stimuler la production d'AMP cyclique dans des cellules exprimant le CRF-R2.alpha. ou .beta.. Ainsi, l'affinité est suffisamment élevée pour que l'urocortine III puisse éventuellement agir comme un agoniste indigène du CRF-R2. Toutefois, il est également probable que l'urocortine III soit un agoniste plus puissant d'un récepteur restant à identifier.
