Patent CA-2182516-A1 (CA)
Title: Probes labelled with energy transfer coupled dyes
Inventor: MATHIES RICHARD A
IPC: C12Q1/68
Filed: 1995-01-30
Abstract: Compositions are provided comprising sets of fluorescent labels carrying pairs of donor and acceptor dye molecules, designed for efficient excitation of the donors at a single wavelength and emission from the acceptor in each of the pairs at different wavelengths. The different molecules having different donor-acceptor pairs can be modified to have substantially the same mobility under separation conditions, by varying the distance between the donor and acceptor in a given pair. Particularly, the fluorescent compositions find use as labels in sequencing nucleic acids.

Patent CA-2186719-A1 (CA)
Inventor: ROSS DENWOOD F III
IPC: G01B11/255
Filed: 1996-09-27
Abstract: An arrangement for measuring desired parameters of a contact lens by optical sectioning which comprises a support fixture on which a contact lens is positioned. The support fixture includes a container in which a pedestal is positioned, and the container is filled with a saline solution. The contact lens is placed on the pedestal completely immersed in the saline solution. A line of light is generated and directed by imaging and shaping optical elements over the edge of the container and through a selected diameter of the contact lens. An imaging camera detects and image of the light scattered at the surfaces of the contact lens at the selected diameter, which is captured by a frame grabber and is digitally stored for subsequent image processing and determination of the desired parameters of the contact lens. The analysis provides at least four basic parameters of the contact lens including the diameter (D), front radius of curvature (FC), back radius of curvature (BC), and center thickness (CT), and can also provide the lenticular curve radius, the peripheral curve radius, the sagittal height, aspherical forms and deviations of the several measured curvatures, and the power of the lens.

Patent CA-2198660-A1 (CA)
Inventor: PUTT SALLY A
IPC: G01R31/50
Filed: 1997-02-27
Abstract: A monitor/analyzer for an ac electrical system can be programmed through a display on the front panel to respond to selected events by generating triggers signals when selected monitored electrical parameters including neutral current exceed programmed thresholds. The trigger signals initiate simultaneous waveform capture of multiple waveform in the ac system. Multiple trigger signals result in sequential waveform capture so that if a plurality of triggers are programmed for the same event, extended waveform data is captured for the event. Alarm screens are generated inresponse to the events, as well as for hardware failure, an excessive neutral-to-ground voltage or reverse sequence.

Abstract: A process for color overprinting onto a thermally printable receiving surface (20) includes using a thermal printer (10) and transfer foils (24) to print a first layer of color printing medium (42) onto a portion of the receiving surface, and then using the thermal printer to print at least a second layer of translucent colored printing medium (44) onto the receiving surface on top of the first layer.  An index of overprint colors (46) can be created by the process for use in matching colors printable by the overprinting process to the colors on an original graphic.  The index may be used manually or in a computerized printing process to determine the number of transfer foils required to reproduce an original graphic, and their order of use.
Patent CA-2219575-A1 (CA)
Title: Filter device
Inventor: KUBO HIROYUKI
IPC: H01P5/08
Filed: 1997-10-29
Abstract: In a filter device, an electrically conductive leaf member is mounted on a coupling loop by soldering or the like.  By bending the conductive leaf member and adjusting the bending angle, the number of magnetic lines of force to be blocked, that is, the degree of magnetic coupling is controlled.  Therefore, when the mounting position of the leaf member is predetermined, the parameter of adjustment can be limited to the bending angle, and the adjustment is thereby facilitated.

The circuits can be designed for bidirectional operation (Figure 1) and for cascadable modules for multiplexers/demultiplexers with an add-drop function (5) and enable transmission and reception to be carried out simultaneously.

Patent CA-2234890-A1 (CA)
Inventor: PRIDE RUSSELL DESMOND
IPC: G01M3/28
Filed: 1996-10-17
Abstract: Cette invention concerne un appareil (20) raccordé par exemple à une section isolée d'un réseau  domestique de gaz soupçonné de fuir. Cet appareil détermine, sur une période de temps préétablie, la chute de pression résultant d'une fuite de gaz et, ensuite, la chute de pression résultant non seulement de la fuite mais aussi d'un soutirage par un orifice calibré de l'appareil. Ces données sont utilisées par un calculateur intégré à l'appareil pour déterminer le débit réel de fuite dans le réseau. La méthode appliquée rend inutile la repressurisation du réseau entre lectures de la chute de pression, et il n'est pas nécessaire non plus de connaître ou d'estimer le volume du réseau testé.

IPC: E06B3/99
Filed: 1998-05-19
Abstract: A window with an outer frame for mounting in a window opening in a structure, this outer frame having on the sides thereof sash tracks or channels facing one another across the window space. Window sashes containing a single window pane are positioned between and securable in such channels in a manner allowing them to be slid therealong for opening and closing the window.  Protuberances extending from the window frame secure the window sashes in the channels so as to allow sliding therealong, and removing such window sashes from those channels is accomplished by removing the protuberances therefrom. A  blocking panel is positionable in the outer frame in the absence of such window sashes, and can be removed therefrom in the absence of such sashes but not when the sashes are present. A relatively rigid tube structure that can be formed in a coarse mesh is provided for affixing to the panel frame in the blocking panel asis a finer mesh screen structure to thereby provide security against entrance through the window space.
