Patent CA-2196153-A1 (CA)
Inventor: FYLES KENNETH MELVIN
IPC: C03C4/02
Filed: 1997-01-28
Abstract: A method of making glass in which a first glass composition is fed to a furnace and the densities of such glass is determined. The composition is then changed to produce a second glass which has substantially different properties from the first glass, the change to the composition being such that the desired properties are produced in the second glass whilst simultaneously maintaining the densities of the second glass substantially equal to that of the second glass. The first glass may be a clear glass whilst the second glass may be a tinted glass. In such a case, the tinted glass may contain iron and the densities are maintained substantially equal by utilising the iron to replace calcium oxide in the clear glass composition.

IPC: B60R16/02
Filed: 1997-02-13
Abstract: An electronic coupling control system for a vehicle trailer hitch assembly having a hitch plate in which a throat is defined for receiving a trailer kingpin and having a locking mechanism for locking the kingpin in the hitch throat. The electronic coupling control system includes a trailer proximity sensor for sensing when a trailer is in proximity to the hitch assembly, a kingpin sensor for sensing the presence of the kingpin in the hitch throat, a lock sensor for sensing when said locking mechanism is in a locked and secured position, and indicator means located in the vehicle for providing hitch coupling status information to an operator of the vehicle. The indicator means is coupled to the trailer proximity, kingpin, and lock sensors for informing the operator when a trailer is in proximity to the hitch assembly, when the kingpin is positioned in the hitch throat, and when the locking mechanism is in a locked position. The indicator means may include an indicator light and control circuit. The electronic coupling control system may further include an interface for coupling to a control input of an electrical control system of the vehicle, wherein the control circuit is coupled to the interface for generating and providing a control signal to the vehicle electrical control system when the locking mechanism is not in a locked position such that a vehicle function, such as the vehicle's brakes are operated. The electronic coupling control system may also perform a self-diagnostic routine to insure proper operation of its components when the vehicle ignition is turned ON.

Patent CA-2207871-A1 (CA)
Title: Breathable liquid elimination analysis
Inventor: WOLFSON MARLA R
IPC: A61B5/083
Filed: 1995-12-28
Abstract: The amount of breathable liquid eliminated from a mammal through volatilization in the lungs and/or through skin transpiration, is detected by measuring the amount of saturation of the expiratory gas by vapors of the breathable liquid. Instantaneous saturation values are employed to gauge the amount of interaction in the lungs between the breathable liquid and respiratory gas flowing therein, and to control selected feedback operations to maintain the maximum possible amount of interaction therebetween. The saturation level of expiratory gas is also employed to optimize operating parameters of a system for recovering the breathable liquid from the expiratory gas, directly from the patient (24), or from gas of liquid ventilator (26). The saturation level of expiratory gas is also employed to perform functional residual capacity studies and to correct to errors in conventional functional residual capacity measurements performed while a patient undergoes partial liquid ventilation. When breathable liquid is employed as a blood substitute, the quantification of the loss of the breathable liquid from volatilazition and transpiration helps to determine when to replenish the breathable liquid in the bloodstream. Vapors of one form of breathable liquid, perfluorocarbon, are employed to determine the functional residual capacity of a mammal's lung.
