Patent CA-2153811-A1 (CA)
Title: Door scriber
Inventor: SIINO ROBERT
IPC: B23B49/04
Filed: 1995-07-13
Abstract: This invention is a tool which is used for marking a line on an object that has to perfectly line up to an adjacent object.  In this case this tool is being used in the security alarm installation trade and is being used to perfectly line up a recessed door contact and magnet.  For example when a recessed door contact is installed, a 3/8" hole is drilled into the door frame for the contact to seat in, a 3/8" hole also has to be drilled into the door so that the magnet can be installed, this is a very hard task to accomplish since you cannot see where you have to mark and drill the hole because to line them up you would have to close the door.  What this invention does is that it allows you to scribe the door even when it is closed and much more accureatly since it marks the line directly in front of the 3/8" hole that was drilled into the door frame.  This is how the invention works: Once the 3/8" hole is drilled into the door frame, insert the barrel of the tool which is labelled D in figure 1.          The barrel of the tool must be inserted all the way in until the base of the tool which is labelled C in figure 1 lays perfectly flat with the door frame.  Then the door must be closed, and the shaft of the tool which is labelled B in figure 1 must be rotated one half of a turn (180 degrees).     Once this step has been completed, the door will have a vertical line scribed on it by the tool.  The line on the door was scribed by the scriber which is labelled A in figure 1.          The scriber which is labelled as A in figure 1 is an extension of the shaft which is labelled as B in figure 1, it is just bent at a 90 degree angle, hardened and sharpened.  This method of marking the door is much more accurate then other methods.          It is also less time consuming, other methods of installing these recessed door contacts was just to "eyeball" the area that had to be drilled.

Patent CA-2166220-A1 (CA)
Inventor: BATES DARREN
IPC: B29C63/36
Filed: 1994-07-05
Abstract: L'invention concerne des garnitures souples destinées à être utilisées dans des canalisations et passages souterrains. Les garnitures comprennent un matériau absorbant qui est impregné de résine synthétique durcissable pouvant durcir lorsque la garniture est positionnée sur la surface de la canalisation ou du passage de façon à former un tuyau rigide à l'intérieur de la canalisation. Le durcissement de la résine est réglé par remplissage de micropores ou de particules microporeuses dispersées dans la résine, avec un agent de durcissement. L'agent de durcissement est libéré uniquement lorsque la résine est soumise à l'application d'énergie telle que de l'énergie acoustique et/ou de la chaleur. Un procédé préféré consiste à inclure des particules magnétiques à température de Curie dans la résine et à les exciter (et donc les chauffer) par application d'un champ magnétique alternatif haute fréquence. La chaleur dégagée par les particules magnétiques provoque l'ouverture des particules microporeuses et la libération de l'agent de durcissement, et donc le durcissement de la résine. L'invention permet également d'assurer l'absorption de l'agent de durcissement par la couche absorbante en premier lieu à l'aide d'énergie acoustique.

Patent CA-2182809-A1 (CA)
Title: Communication method and apparatus
Inventor: SMITH RICHARD DOUGLAS LANE
IPC: H04N1/32
Filed: 1994-07-27
Abstract: A facsimile interface apparatus is connected between facsimile terminals communicating via a satellite. The interface apparatus converts a conventional facsimile signal to a signal suitable for transmission to the satellite. However, the interface apparatus and the satellite may incur a long delay such that the calling facsimile terminal repeats a transmitted signal while the response to that signal is being received over the satellite. To overcome this problem, the facsimile interface apparatus connected to the calling terminal sends, after a period t1, a holding signal to the calling terminal, to prevent the calling terminal from repeating the transmitted signal. After a further period t2, the interface apparatus sends a command repeat signal to the calling terminal, so that the transmitted signal is repeated if the called terminal has not transmitted a response.
