Patent CA-2229653-A1 (CA)
Title: Machine for synthesizing oligonucleotides
Inventor: HOLMBERG LARS
IPC: C12N15/09
Filed: 1996-08-16
Abstract: A machine (8) for synthesizing oligonucleotides has individual pumping modules for connection to each of a number of different monomers and to other fluids used in the synthesizing process. Each pumping module includes a pump (50-59) and a three-port/three-way valve (30-39) with the first inlet port connected to receive the fluid, and the second port connected to receiving a flushing agent, such as acetonitrile. A valving arrangement (98, 102) downstream from the pumping modules selects a monomer. The selected monomer and other fluids pass through flow sensors (110, 112, 114) which provide signals to a controller, which uses these signals to regulate the pumping of the pumps (50-59). At least some of the valves allow multiple inlet ports to be kept open at the same time, thus allowing certain of the liquids to be mixed within the valves. The various pumps, valves and sensors are mounted to the exterior of a cabinet (170) and arranged such that the liquid handling portions are exterior to the cabinet (170), while electrical portions are within the cabinet (170). Air is continuously purged within the cabinet (170) in order to prevent the introduction of solvent fumes near electrical components. The machine (8) can produce up to 100 millimoles of oligonucleotides, and the arrangement provides for the efficient use of materials.

Patent CA-2231521-A1 (CA)
Inventor: VANHECKE FRANCK
IPC: C09K23/00
Filed: 1996-10-15
Abstract: A release agent for rolls, particularly rolls in paper making such as press rolls is described which comprises one or more release active components and optionally conventional additives and which is in the form of a microemulsion. Suitable compositions include those which are essentially free from water and to which water is only added before actual application. The microemulsion or the microemulsion, which upon water dilution is at least intermediately formed, is unstable upon dilution with water to the application concentration which results in a good and homogeneous application of the active ingredients to the press surface. In this way the efficiency of the release agent and the release properties of the rolls are improved. Further, less deposits are formed on the roll surface.

Patent CA-2235900-A1 (CA)
Inventor: KATUSZONEK MARK A
IPC: H04L69/40
Filed: 1998-04-24
Abstract: A test of digital communications facilities identifies facilities that have AMI/B8ZS line coding mismatches. A test apparatus and method transmits a test tone signal simultaneously on contiguous channels over a trunk to produce a series of consecutive zeros which span the two channels to invoke the B8ZS code. The test apparatus method then compares the sent signal to the received signal to determine whether the received signal deviates from predetermined thresholds. If so, then the currently analyzed channel suffers an AMI/B8ZS mismatch.

Patent CA-2237346-A1 (CA)
Inventor: LOOMIS ROBERT MARK
IPC: B23P6/00
Filed: 1998-05-11
Abstract: This invention provides a method for restoring at least one means defining a railroad spike hole located in a used railroad tie.  In this way, the restored railroad tie can be reused in subsequent rail replacement operations.  The restored railroad tie is capable of having a railroad spike penetrate and be retained within the confines of the restored railroad spike hole without substantial bending problems.  The used railroad tie provided has at least one spike hole located therein.  In each the means defining a railroad spike hole is formed a polymeric plug.  The polymeric plug comprises a substantially non-foaming, non-cellular polymeric material.  The polymeric material preferably comprises a polyurethane.  The polymeric plug infiltrates and tightly bonds with the railroad spike hole to prevent moisture infiltration. Thus, substantial tie rot due to moisture is impeded, and the leaky railroad spike hole is effectively and efficiently dammed to enable complete filling thereof. The polymeric plug is capable of penetration by and retention of the railroad spike therewithin.

Title: Recliner apparatus
Inventor: HOWARD TIMOTHY L
IPC: B60N2/427
Filed: 1998-05-26
Abstract: Apparatus for adjusting the spatial relationship between the bottom and the back of a chair which may be subjected to severe mechanical stress, as in the case of a vehicle crash, the seat and the back being operatively connected respectively to two oppositely threaded portions of a rotatable shaft which is adapted to be rotated in one direction or the other to produce the desired change in spatial relationship, the arrangement providing the combination of exceptional strength in the event of a crash and reduced cost.          The operative connection between the chair parts and the shaft includes two non-rotatable parts engaged respectively with the oppositely threaded shaft portions SG as to move in and out with respect to the shaft as the latter is rotated, and a housing which permits those parts to thus move while preventing their rotation.
Patent CA-2241407-A1 (CA)
Title: Apparatus for connecting advertising substrate to trucks
Inventor: HICKS CHARLES H
IPC: G09F21/04
Filed: 1998-06-24
Abstract: A substrate upon which an advertising message may be imprinted is secured in overlying relation to an overhead-opening type of truck or trailer rear door by an assembly that includes an elongate coil spring positioned on an interior side of the overhead door. The lowermost end of the spring is secured to the interior side of the door and the uppermost end of the coil spring is connected to a lower end of a winch by a nonstretchable strap. The upper end of the winch is connected by a nonstretchable strap to a rigid rod to which the upper end of the substrate is attached. Tightening the winch increases the tautness of the substrate and loosening the winch decreases the tautness. When properly adjusted, the substrate is taut throughout the entire door-raising and lowering procedure, even though the substrate is substantially nonstretchable and even though the opening of the door requires the substrate to extend a greater distance than when the door is closed. The difference in length is compensated for by the coil spring when its resistance is properly adjusted by the winch. An apparatus including opposed, "L"-shaped brackets that are interconnected and drawn toward one another by an elongate bolt tightens the forward ends of side-covering substrates when clearance space is limited between a cab and the cargo-receiving part of a truck or trailer.

Patent CA-2244809-A1 (CA)
Title: Facsimile-based video compression method and system
Inventor: BERGER TOBY
IPC: H04N7/32
Filed: 1997-02-13
Abstract: A method and system (10) for compressing and decompressing video image data in real time employs thresholding and facsimile-based encoding to eliminate the need for computationally intense two-dimensional transform-based compression techniques. The method operates first by forming a difference frame which contains only information pertaining to the difference between a current video image frame and a computed approximation of the video image frame. The difference frame is fed to a thresholder (32) which categorizes each pixel in the frame as being either in a first set having intensities above or at a preset threshold, or a second set having intensities below a preset threshold. A facsimile-based compression algorithm in an encoder (44) is then employed to encode the first set of above or at threshold pixel locations. To compress the intensity data for each above or at threshold pixel, a quantizer (40) and a lossless encoder (50) are preferably employed.

Abstract: Ce système et ce procédé de radiocommunications fait appel à un préréglage du niveau de puissance pour atténuer l'augmentation du brouillage causée par la transmission discontinue par les postes mobiles. Dans la liaison descendante, le préréglage de la puissance est effectué par la détection de l'entrée de postes mobiles dans une cellule (ou de leur sortie de la cellule), et, en réponse à cette détection, par le calcul d'une pluralité de valeurs d'ajustement de puissance pour chaque poste mobile dans la cellule. Dans la liaison ascendante, le préréglage de la puissance est effectué par l'estimation d'une augmentation du brouillage causée par l'entrée de postes mobiles dans une cellule (ou leur sortie de la cellule), et par l'utilisation de cette estimation pour calculer une puissance cible mise à jour pour chaque poste mobile dans la cellule. Le préréglage de la puissance est également amorcé en réponse au passage d'au moins un poste mobile d'un mode à débit de données élevé à un mode à débit de données bas, ou inversement.
