Patent CA-2011011-A1 (CA)
Title: Apparatus and method for changing coolant in vehicle cooling system
Inventor: ANDERSEN ROBERT A
IPC: F01P11/06
Filed: 1990-02-27
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus and method for changing the antifreeze in a vehicle requires only a garden hose and opening of the radiator cap.  Water from the hose is utilized to prime a conduit for siphoning used coolant from a side tank radiator and for refilling the radiator.  By operating the vehicle with fresh water in the radiator, coolant remaining in the system is mixed with the water, and repeated drainings decrease the remaining used antifreeze by about one-half each time.  After removal of the desired amount of antifreeze, new antifreeze may be placed in the radiator.

Title: Optical waveguide and method for its manufacture
Inventor: KALNITSKY ALEXANDER
IPC: G02B6/122
Filed: 1990-04-04
Abstract: An optical waveguide is made by forming a layer of SiO2 on a substrate and implanting a region of the SiO2 layer with Si ions to define a region containing a stoichiometric excess of Si which defines a region having an elevated refractive index surrounded by a region having a lower refractive index.  The resulting optical waveguide is stable at the high temperatures required for many semiconductor processing methods, and is useful for optical interconnection in integrated optical and optoelectronic devices.

Title: Eavestrough hook and leaf guard
Inventor: BRANT ANTHONY W
IPC: E04D13/04
Filed: 1990-04-30
Abstract: ABSTRACT OF THE DISCLOSURE        The eavestroughing system uses hidden hooks in combination with a particular eavestrough which allows the effective placement of a leaf screen within the eavestroughing system.  The leaf screen is engaged either side thereof in a simple manner, allowing convenient ease of insertion of the screen within the eavestroughing system and in a predetermined orientation.  The eavestrough section cooperates with the hanger to provide support for the screen adjacent a forward edge of the screen and also serves to hide the forward edge of the screen within the eavestrough section.  The preferred orientation of the screen advantageously is disposed at a downwardly extending angle to the forward edge of the eavestrough to encourage the movement of debris across the screen towards the forward edge where it can easily be removed by the end user and/or removed by natural causes.  This natural tendency to move the debris across the screen reduces accumulation of debris on the screen. Furthermore, the particular support arrangement has higher support adjacent the forward edge and therefore, if there is any accumulation, there is better support for the screen at this position.  The present system provides a simple and convenient arrangement for a fully integrated plastic eavestroughing system.

Title: Preparation of a catalyst useful in the dimerization of butadiene
Inventor: HEATON DUANE E
IPC: B01J31/18
Filed: 1990-05-07
Abstract: Abstract Catalysts suitable for the dimerization of a diolefin, e.g. butadiene to 4-vinylcyclohexene, are prepared by reacting (1) iron chloride and sodium nitrite or alternatively (2) iron nitrosyl chloride with (3) carbon monoxide in an organic solvent in the presence of a readily oxidizable metal, e.g. tin.  The catalyst solution is filtered prior to use to remove particulate matter such as unreacted tin.       While the reaction employing iron chloride and sodium nitrite is preferred, the catalyst produced by either method contains a minimum of reducing agent and by-products.  It can be isolated and stored in the absence of the butadiene monomer while retaining its stability and activity.     37,439-F

IPC: B24B3/36
Filed: 1991-02-13
Abstract: Automatic Knife Sharpening System For Forage Harvesters Abstract of the Disclosure In a forage harvester having a motor driven sharpening stone driven back and forth along a path parallel to the axis of a rotating cutterhead to sharpen the knives of the cutterhead, and a door which normally prevents access to the knives, a control circuit is provided for controlling the opening of the door, the movement of the sharpening stone to sharpen the knives, and the closing of the door after the knives have been sharpened.  The circuit is controlled by switches located at an operator's control panel and accessible to the operator while he is in the driver's seat of the harvester so that the operator does not have to leave his driving position to accomplish the knife sharpening operation.  The circuit includes visual indicators located on the control panel for indicating the status of the circuit during the entire operation.  The circuit includes a sensor circuit for sensing the rate of rotation of the cutterhead, the sensor circuit preventing knife sharpening from taking place unless the cutterhead is rotating at a rate greater than the rate required for proper sharpening of the knives.

Title: Actuation cell response and mapping determinations for web forming machines
Inventor: CHEN SHIH-CHIN
IPC: G01N33/34
Filed: 1991-02-21
Abstract: A standard control signal for a web forming machine is temporarily interrupted and replaced by a perturbing signal or signals which are applied to one, a grouping, or all of a series of actuation cells of the web forming machine.  One or more actuation cells are driven with an alternating perturbing signal(s) which generate a corresponding action in the actuation cell(s).  The perturbing signal(s) alternates from a neutral position of the cell and is selected to minimize mean effects over any given period of time.  The effects of the alternating signal(s) on the web appear within the area of the web which is affected by the actuation cell(s) such that the mapping and the response of the actuation cell(s) can be determined by monitoring that portion of the web which is formed while the alternating signal(s) is applied to the actuation cell(s).  The mapping(s) and/or response(s) of the actuation cell(s) are obtained by correlating the perturbing signal(s) and a web property signal or profile signal obtained by monitoring the web formed by the machine.  The perturbing signal(s) is defined by a pseudo-random binary sequence with multiple signals being selected to be statistically independent of one another. To ensure that the web is not perturbed beyond defined specifications, the perturbing signal preferably is gradually increased in amplitude and is terminated individually for each actuation cell upon reaching a usable amplitude.
