Patent CA-2061904-A1 (CA)
Title: Phase modulated fiber optic gyro accommodating angular rate reversals
Inventor: ISHIGAMI MOTOHIRO
IPC: G01C19/72
Filed: 1992-02-26
Abstract: The present invention relates to a phase modulated fiber optic gyro that accommodates angular rate reversal.  The gyro is a linear phase ramp type in which clockwise and counterclockwise light beams propagate through a looped optical transmission line.  A ramp signal is produced that provides each of the light beams with a ramp phase of a slope which cancels their phase difference corresponding to an input angular rate to the optical transmission line and a biasing signal which causes the phase difference between the both light beams emitted from the optical transmission line to alternate between +.pi./2 rad and -.pi./2 rad.  The input angular rate is obtained on the basis of the frequency of the ramp signal.

Title: Improved through-the-wall vented water heater
Inventor: DOSS GARRETT L
IPC: F24H1/20
Filed: 1993-03-22
Abstract: The present invention provides a water heater capable of exhausting flue gases from an interior space of a building to an exterior space and is adapted far installation through an upstanding wall. The water heater has an insulated tank with a water inlet and a water outlet together with a flue pipe opening at one end thereof beneath the tank upon a combustion chamber containing a fuel burner. The other end of the flue pipe opens at the top of the tank upon a flue gas collector and has a flue gas restricter for restricting the outward flow of flue gases from the flue pipe. The collector includes a collector box connected to the top of the water heater above and in alignment with the flue pipe, a blower and a low temperature flue gas exhaust line. The collector box has at least one air inlet for mixing air from the interior space of the building with flue gases exiting the flue pipe to inhibit condensation and reduce the temperature of the flue gases flowing through the exhaust line.      The water heater has a control for sensing the temperature of water in the tank and regulating the amount of fuel supplied to the burner. The water heater also includes a device for activating and deactivating the blower in response to controlling the fuel. The water heater further includes a sensor for sensing the temperature of the mixture of flue gases and air from the interior space and for interrupting the fuel supply to the burner in response thereto.      A further sensor senses the temperature of the mixture of flue gases and air from the interior space to continue blower operation for a desired period of time after the fuel burner stops operating.      There is further provided a valve for preventing flow of fuel to the fuel burner when the power supply to the water heater has been interrupted.
