Title: Method and apparatus for synchronizing, displaying and manipulating text and image documents
Inventor: RIVETTE KEVIN G
IPC: G06F3/048
Filed: 1994-11-18
Abstract: The present invention provides a method and apparatus for extracting, syn-chronizing, displaying, and manipulating text and image documents in electronic form for display. In the preferred embodi-ment of the present invention, text and im-age files for documents, such as for exam-ple patent documents, are initially stored on separate magnetic tape media. These data files are extracted from the respec-tive tapes and placed onto a faster medium, such as a hard disk drive. The text and image files are synchronized to produce Equivalent Files using heuristic algorithms to create an approximate equivalence re-lationship between the text and the image files. The Equivalent Files and image files residing on, for example, a hard disk drive or compact disk (CD), are coupled as a ne-source to a computer display system. The graphic user interface of the present inven-tion permits the user to display, manipu-late, and edit the Equivalent File created using the process of the present invention and to simultaneously view the image file on the display. Using the graphic user interface of the present invention, a user may create libraries of patent Equivalent Files and image files or documents of another type, as well as open cases to include a plurality of different patents or other documents. The Equivalent File may be selectively viewed on the display in an equivalent window. Simultaneous with the viewing of the Equivalent File within the equivalent window, the user may view any portion of an image file within one or more image windows on the display. A variety of other features and functions are provided by the present invention for the manipulation and display of patent documents and other documents on the user interface.

Patent CA-2179804-A1 (CA)
Inventor: GRIME THOMAS E
IPC: B05B15/12
Filed: 1996-06-24
Abstract: A VOC (volatile organic compounds) adsorbent material such as an alumino-silicate gel desiccant is treated with a masking agent to reduce its affinity for VOC's to a level that the material can be regenerated at a predetermined low temperature which will not desorb the masking agent. The treated adsorbent material is used to adsorb VOC's and is periodically regenerated with heated air. The treated adsorbent material may be used to adsorb VOC's from recirculated spray booth air while spraying a coating on a workpiece. Subsequent to spraying, the spray booth air is heated to above the VOC regeneration temperature to regenerate the adsorbent material and optionally to cure the applied coating. As the heated spray booth air is circulated through the adsorbent material, the previously adsorbed VOC's are desorbed. The desorbed VOC's may be destroyed by oxidizing, for example, with a catalyst.

Inventor: SEYNISCH ULRICH
IPC: F24F11/76
Filed: 1996-11-20
Abstract: The invention relates to an actuator device for displacing a vent damper of a ventilation apparatus between open and closed positions with respect to a vent opening defined by the ventilation apparatus. The device includes a piston/cylinder mechanism including a cylinder within which a paste-like substance having a highcoefficient of expansion is contained, this substance acting on the piston, through its expansion due to temperature increases, for displacing the piston, which in turn can provide for displacement of the vent damper of an associated ventilation apparatus. Reverse displacement of the vent damper will be induced by a spring acting directly or indirectly on the piston, contraction of the substance in thecylinder due to temperature decreases being required to permit such reverse displacement.
Patent CA-2191291-A1 (CA)
Title: Furnace
Inventor: SAXENA NEERAJ
IPC: F27B5/16
Filed: 1996-11-26
Abstract: A furnace, for instance a reflow soldering oven, in which oxygen concentration is either directly or inferentially sensed within central processing and either one or both of the inlet and outlet sections of the furnace. Signals generated by these sensors are processed in a PID controller to generate a control signal to control the flow rate of inerting gas into the central processing section, thereby to at least inhibit ingress of air into the central processing section. The PID controller is programmed such that its integral error term is set equal to a time average of the oxygen concentrations of the central processing section less an oxygen concentration set point desired for the central processing section. The proportional and differential error terms are set equal to a time average of the concentrations of the central processing section and one or both of the inlet and outlet sections of the furnace less the oxygen concentration set point.

Title: Mapping r- f ablating liquid injecting screw- in catheter mounted electrode
Inventor: MULIER PETER M J
IPC: A61B18/12
Filed: 1995-07-28
Abstract: A method and apparatus for ablation of body tissue. A catheter provided with a hollow needle is employed both for mapping the location to be ablated by injection of an excitability reducing agent and for ablating tissue, employing RF energy in conjunction with an injected, conductive fluid. The hollow needle can be shaped in the form of a spring like helix intended to pierce the surface of the organ and then to penetrate into the tissue under the action of a rotation imposed upon the catheter by the operator. The penetration of the electrode into the tissue guarantees efficiency of ablation and prevents dispersion of energy on not targeted locations. A second ablation electrode may be present in a recessed cavity at the catheter distal end. The injection of cool or warm liquids through the helix like needle requires the liquid to be kept at the wished-for temperature along the length of the catheter. To this objective the catheter main lumen is made into three coaxial channels, the innermost of which carries the injection liquid, and the two others create a two way circuit where another heated or cooled liquid is forced to circulate to maintain the temperature of the injection liquid in the innermost tube at the distored level.

Patent CA-2211187-A1 (CA)
Title: Water-based marker material and a method of manufacturing said material
Inventor: BOLDT PETER-CHRISTIAN
IPC: C09D7/62
Filed: 1996-02-05
Abstract: The proposed marker material is intended for use in laying down thick layers of between 1 and 3 mm in thickness and has a low-viscosity colouring substance content of 40-60 wt %. The colouring substance consists of a quick-drying binding agent based on an anion-stabilised emulsion polymer, pigments, powder fillers and standard additives. The remaining weight percentage is accounted for by coarse fillers with a particle diameter of 0.1 mm. The total solids content is approximately 87-93 wt %. The extremely low proportion of volatile substances and the presence of the quick-drying binding agent reduce the drying times of the markings once applied to a fraction of the time required for conventional formulations and prevent cracks from forming.
