Title: Procede de determination quantitative d'un acide nucleique en solution par mesure de sa conductivite electrique, et appareil pour sa mise en oeuvre
Inventor: CLARKSON JOHN MICHAEL
IPC: C12Q1/6825
Filed: 1997-02-18
Abstract: Procédé pour l'évaluation d'une propriété ou d'un paramètre d'une matière à base d'acides nucléiques, la conductivité électrique de ladite matière étant associée cette propriété ou ce paramètre. Le procédé consiste à mesurer la conductivité électrique de la matière à base d'acides nucléiques, et à évaluer, à partir de la mesure obtenue, la propriété ou le paramètre de la matière avec référence à une relation déterminée entre la conductivité électrique et ladite propriété ou ledit paramètre. Ce procédé se fonde sur la découverte que l'on peut évaluer certaines propriétés importantes des acides nucléiques, dont la détermination quantitative est fréquemment souhaitable, en mesurant la conductivité d'une solution d'un ou plusieurs acides nucléiques. Les variations de ces propriétés peuvent se traduire par des variations correspondantes de la conductivité électrique. A titre d'exemple, les propriétés importantes que l'on peut déterminer sont la concentration d'acides nucléiques dans une solution et le poids moléculaire d'une espèce d'acide nucléique.

Patent CA-2257711-A1 (CA)
Inventor: KETTLE PAUL J JR
IPC: B60T17/04
Filed: 1999-01-04
Abstract: An adapter is designed to interconnect the two glad hands that extend from the adjacently disposed ends of a pair of rail vehicles in a train. The housing of the adapter includes first and second connector bodies and an intermediate portion situated between the two connector bodies. The adapter housing encloses a flow chamber that runs from the first connector body through the intermediate portion to the second connector body. The intermediate portion defines a vertically disposed access port in communication with the flow chamber of the adapter housing.      The connector bodies are formed on opposite, vertically oriented sides of the adapter housing. Each connector body features a mating surface from which a flow port in communication with the flow chamber emerges. Each connector body also includes a mechanism that allows the connector body to mechanically couple to one of the glad hands. When so coupled, the mating surface of the connector body is aligned with the mating surface of its corresponding glad hand with a sealing member of the glad hand held in compression therebetween. By coupling the glad hands to connector bodies of the adapter, a leak proof passage is provided from one glad hand through the flow chamber and the flow ports of the adapter housing to the other glad hand. It is directly to the access port or indirectly via a fitting that an external device can connect for the purpose of affecting the pressure contained by the brake pipe of the train.

Title: Segmented roll product for enhanced cohesive
Inventor: PETERSON WAYNE C
IPC: B65D65/28
Filed: 1999-03-22
Abstract: A Z-fold mailer type business form intermediate using patterns of pressure activated cohesive has the cohesive in patterns for both sealing along the end and side edges of the final form in the form of discrete elements spaced from each other in such a way that when the business form is in either roll or stack format the individual cohesive elements substantially do not overlap each other. The cohesive elements typically are in the form of rectangles for example those along the end edges and the fold lines having a length of about .9 cm with space in between them of about 1.3 cm. The cohesive patterns along the side edges may be spaced from each other not only in a dimension parallel to the end edges, but also where cohesive patterns are provided on opposite faces of the second panel of the intermediate, they may be positioned so as not to overlap in a dimension parallel to the side edges
Patent CA-2267268-A1 (CA)
Inventor: ROY FERNAND
IPC: E06B9/264
Filed: 1996-11-12
Abstract: The window unit of the invention comprises four peripheral channel members linked with comer members to form a window frame. Two glass panels are spaced by this frame to form an inner chamber, the venetian blind structure of the invention being located completely therein. The venetian blind structure comprises a plurality of horizontal slats pivotally supported at both their extremities and each having an integral toothed wheel engaging a complementary rack on an actuator bar, the latter positioned adjacent to a side peripheral channel member and being free to move upwards or downwards along it. This upward or downward movement imparts a pivoting movement to the slats. The venetian blind structure further comprises a support channel member supporting a reversible electrical motor having a driving shaft. This shaft is aligned to engage properly the actuator bar.      When the driving shaft rotates, it imparts a linear upward or downward movement to the actuator bar, thus pivoting the slats consequently. The alignment of the shaftis done by means of an L-shaped plate bored and threadingly engaged by an alignement sleeve, the latter being coaxially engaged by the driving shaft. This alignment of the shaft prevents the parts of the venetian blind structure from moving in undesired directions, relative to one another, and therefore reduces the chances of breaking these parts.
