Patent CA-2171096-A1 (CA)
Inventor: WALLACE ROBERT BRUCE
IPC: C12N15/09
Filed: 1994-09-01
Abstract: L'invention concerne un procédé de clonage d'ADN produit par extension d'amorce comprenant un ADN synthétique amplifié par PCR, généré par transcriptase inverse ou obtenu par extension d'amorce. Plus particulièrement, elle concerne un procédé dans lequel les restes d'alcane diol contenant des amorces oligonucléotidiques sont incorporés dans l'ADN par extension d'amorce suivie par le clonage direct de l'ADN cible. Après la transformation, l'hôte coupe le reste au moyen de son système endogène de réparation d'ADN. Ce procédé de clonage représente une amélioration par rapport à l'état actuel de la technique nécessitant soit une digestion enzymatique de restriction du produit d'ADN synthétique amplifié par PCR, généré par RT ou obtenu par extension d'amorce, un clonage à extrémité franche, soit l'utilisation de sites de restriction dans le vecteur de clonage pouvant accepter des produits de PCR par l'intermédiaire de l'activité de transférase terminale fortuite de l'ADN polymérase I de T. aquaticus. La possibilité de cloner facilement tout produit de PCR ou de RT dans tout site de restriction avec un dépassement en 5' représente un progrès important par rapport à l'état actuel de la technique.

Title: Process for removing by-products from diurethanes
Inventor: DEIBELE LUDWIG
IPC: C07C269/08
Filed: 1996-06-19
Abstract: Low-boiling by-products are removed from diurethanes prepared by a phosgene-free process by carrier vapor distillation using alcohol vapor, preferably the vapor of the basic alcohol found in the diurethane, as the carrier vapor. The diurethanes freed of low-boiling by-products in this manner may be thermally decomposed to produce diisocyanates.

Title: Extended life brake cylinder holder
Inventor: KARCSEWSKI PATRICIA T
IPC: F16D65/28
Filed: 1996-09-13
Abstract: A push rod holder for use with a brake cylinder of a railroad vehicle is disclosed.  The push rod holder includes an annular outer metal member and an annular inner elastomeric member.          The annular inner elastomeric member is molded to an interior surface of the annular outer metal member.  The push rod holder defines at least one set screw throughhole and a pair of aligned holder pin throughholes.  Each of the throughholes is oriented perpendicularly to a longitudinal axis of the push rod holder.  The brake cylinder includes a hollow piston rod and a push rod assembly inserted therein.   The push rod holder concentrically fits onto the hollow piston rod.  The annular inner elastomeric member assures that the push rod holder fits snugly about the hollow piston rod.  At least one set screw is used to attach the push rod holder to the hollow piston rod via the at least one set screw throughhole.  A holder pin device is used to lock the push rod holder to the hollow piston rod and the push rod assembly contained therein.   The annular inner elastomeric  member  dampens  vibrations  encountered  at  the junction of the push rod holder, hollow piston rod and push rod assembly.  The push rod holder thus reduces the likelihood of damage  occurring  to  these  components  and  prolongs  the operational life of the brake cylinder.

Title: Transmission control method in network system for signal transmission by plural channels and network system therefor
Inventor: HOUJOU KAZUHIKO
IPC: H04B10/291
Filed: 1997-01-31
Abstract: In a network system for effecting signal transmission by plural channels, there are provided plural channel alteration units each of which is adapted to receive signals through plural channels and to output each of the signals entered by said plural channels in any of plural channels . Transmission control is executed in such a manner that mutually proximate plural signals, which have to be outputted by a designated same channel among the plural channels from a first one of the plural channel alteration units, are entered through respectively different channels into the first channel alteration unit. As the first channel alteration unit receives the plural signals by different channels, there can be resolved the drawback of a long waiting time for the output of the signals by a desired channel, encountered in case the signals are entered by a signal channel.

Abstract: Lors de l'identification d'un objet dans une image, des identifications redondantes de l'objet peuvent se produire très fréquemment. L'invention a trait à des procédés d'analyse d'images destinés à résoudre ces identifications redondantes d'un objet. Plus spécifiquement, l'invention concerne des méthodes d'identification d'objets obtenant des représentations multiples du même objet. De plus, lesdites méthodes d'identification peuvent identifier des objets vides ou en forme d'anneau lorsqu'une seule recherche ou des recherches multiples de l'image sont effectuées. De plus, l'invention est utile pour résoudre divers objets distincts dans les cas où d'autres méthodes d'identification utilisant une recherche soit unique soit multiple ont identifié ces objets distincts comme étant un seul objet en forme de masse. L'invention peut être utilisée, par exemple, pour déterminer si un objet plus petit est contenu à l'intérieur d'un objet plus grand.

Title: System and method for wireless transmission of digital data using differentially encoded pilot words
Inventor: WRIGHT ANDREW S
IPC: H04B7/005
Filed: 1995-11-22
Abstract: A system and method for transmitting digital data over a wireless channel uses periodically-transmitted, differentially encoded pilot words to allow a receiver to rapidly synchronize with a transmitter. Each differentially encoded pilot word comprises at least two pilot symbols that are separated by a fixed difference. The receiver monitors differences between symbols to locate the differentially encoded pilot words, and to thereby become synchronized with the transmitter. Once the receiver becomes synchronized with the transmitter, the receiver uses the pilot symbols of the differentially encoded pilot words to perform channel estimation and compensation.

Patent CA-2208711-A1 (CA)
Inventor: ZELITT SHELDON S
IPC: G02B27/22
Filed: 1995-12-28
Abstract: A 3-dimensional image is obtained from a 2-dimensional display by varying the apparent distance of the image from the viewer on a pixel by pixel basis. This is done by positioning an array of pixel-level optical elements in alignment with the pixels in the image. In a preferred format, each of the optical elements is generally elongate and has a focal length which varies along its length with the result that the point along its length at which light enters the optical element determines the apparent visual distance of the associated pixel from the viewer. In the case of a cathode-ray tube application, controlling the position of entry of the light is done by controlling the electron beam to move a minute distance vertically as it scans horizontally. In a television application, the vertical distance may be determined by a depth component incorporated in the broadcast signal received by a television set. Applications and embodiments relating to computer monitors, film and still printed imagery are also described.
