Patent CA-2170067-A1 (CA)
Title: Solventless resin composition having minimal reactivity at room temperature
Inventor: MARKOVITZ MARK
IPC: H01B3/40
Filed: 1996-02-22
Abstract: A resin composition is provided that is suitable for impregnating sheet material, including fabrics, films, paper and tapes of the type employed to form prepregs, such as tapes used to form electrical insulation layers on electrical components. The resin composition includes a solid or semi-solid epoxy resin having an epoxide functionality of at least 2.5, a metal acetylacetonate for catalyzing the epoxy resin, and an accelerator of bisphenol A-formaldehyde novolac catalyzed by an acidic catalyst and having a hydroxyl equivalent weight of 120. The resin composition is essentially unreactive at room temperature and at elevated temperatures sufficient to enable permeation of the sheet material by the resin in its manufacture, is essentially unreactive at temperatures required to remove moisture and volatiles during processing of articles wrapped or taped with the sheet material, and cures at a higher temperature without adversely affecting the cure characteristics of the resin composition. The resin composition of this invention achieves the desirable reactivity characteristics noted above, while exhibiting enhanced mechanical, thermal and electrical properties necessary for its use within an electrical insulation composite.

Title: Improvements relating to electrical heating elements and controls therefor
Inventor: O'NEILL ROBERT ANDREW
IPC: H05B1/02
Filed: 1994-10-21
Abstract: A planar heating element for an electrically-heated water boiling vessel comprises a stainless steel plate having a printed heating element formed on one side thereof, the printcd heating element being sandwiched between electrically-insulating layers of glass. A control for switching off the element in an overtemperature situation has a primary actuator in the form of a bimetal which directly accesses the printing element through a window formed in the outermost glass insulating layer, and the bimetal is held in a secondary actuator in the form of a thermally-collapsible carrier for the bimetal which contacts the glass insulation around the window. By virtue of this arrangement the primary and secondary actuators are subjected to different temperatures which ensures that the secondary actuator is not susceptible to nuisance operation.

Title: A distributed lightning detection system
Inventor: HEROLD DAVID GEORGE
IPC: G01W1/16
Filed: 1996-09-04
Abstract: A distributed lightning detection system comprises a plurality of lightning detection stations located at different positions with respect to a common frame of reference with the position of at least one detection station being mobile with respect to the common frame of reference.  Each station includes a lightning strike detector, first and second receivers, a processor, and a transmitter.  The first receiver receives signals from at least one common transmitting system, preferably the GPS system, for establishing a common lightning position and occurrence time frame of references for all of the stations.  The processor is governed by a strike indication signal generated by the detector and determines the time of occurrence of the detected lightning strike and the station's own position corresponding thereto.  The processor is further operative to generate a report for each detected strike including data of time of occurrence, station's own position and a bearing signal from the detector corresponding to each strike.  The bearing signal of the mobile stations being compensated for the station's mobility.  The transmitter transmits the strike reports over a data link to other lightning detection stations. The second receiver receives the strike reports from other lightning detection stations over the data link and provides same to the processor.  The processor correlates received strike reports with detected strike reports to determine reports generated from common lightning strikes and computes a range from the station to each of the common lightning strikes based on the data of the correlated strike reports corresponding thereto.

Title: Coating of wax-like materials onto moving strip articles
Inventor: INNES ROBERT ARTHUR
IPC: B05D7/14
Filed: 1995-11-23
Abstract: A process of coating a heat-conductive strip article, e.g. aluminum or aluminum alloy strip (14) used in the automotive industry, with a solid wax-like coating material, preferably a wax-type lubricant. The process involves heating a solid wax-like coating material that melts in a temperature range of about 30 to 100 ~C to form a melt having a viscosity in a range of about 50 centipoise or less and flowing the melt onto a moving surface of the strip article through an elongated slot (15) in a movable coating head having an extended surface adjacent to the slot to form a coating layer on the article.  The coating head is pushed towards the surface of the strip article as the melt is flowed as a coating onto the surface from the slot (15) to reduce a coating thickness by pressing the extended surface of the coating head onto the coating as the coating is formed. The process allows a coating of a wax-like material to be formed to a desired thickness and yet allows the wax-like material to solidify shortly after application to the strip article (14) so that the strip can be coiled without providing a cooling run of undue length or special cooling devices.

Title: A noninvasive method for identifying coronary dysfunction utilizing electrocardiography derived data
Inventor: SEEGOBIN RONALD
IPC: A61B5/0452
Filed: 1997-08-07
Abstract: A method of analyzing experimentally derived electrocardiograph (ECG) data, and system for practicing said method, which allow tracking of subject cardiac status change and which allow surprisingly accurate catagorization of subjects into various abnormal and normal classifications is disclosed.  The presently preferred embodiment of the present invention applies an algorithm which compares representative parameter, (eg.  root-mean-square (RMS) mean), values derived from analysis of a representative composite of selected portions of a number of ECG PQRST waveforms obtained from (ECG3) investigation of a subject, to similarly derived representative parameter, (eg. RMS mean and RMS standard deviation), values present in a compiled data bank derived from (ECG) investigation of numerous normals, in each of a plurality of frequency range bands.   A highly diagnostic numerical "Score" is calculated by addition of "Score" components found to be acceptable under certain mathematical criteria, and provided by the algorithm.   Visually interpretable time domain and power spectral density plots enhance the method.  In addition, comparison of the calculated "Score" to subject cardiac ejection fraction provides indication of risk for sudden death as does the presence of "rhomboids" following a QRS complex in frequency domain plots.   The present invention is directly adapted to tracking subject cardiac status change by substituting a baseline subject data set for the normal population data set.
