Patent CA-2245433-A1 (CA)
Inventor: KIMURA YUJI
IPC: G06F21/10
Filed: 1998-08-24
Abstract: An additional information signal is superimposed on a video signal at a very low level so that it does not stand out on the reproduced image.  Spectral spreading code sequences are generated corresponding to different predetermined parts of the video signal.  Bit information signals of the additional information signal comprising plural bits are spectrally spread by the spreading codes to generate spectrally spread bit information signals corresponding to the plural bits.  The  spectrally spread bit information signals are superimposed on corresponding different predetermined parts of the video signal.  As high priority bit information signals of the spectrally spread additional information signal are superimposed on high priority parts of the video signal,  high priority information in the additional information can be protected even if the video signal is modified.

Title: Computer control of railroad train brake system operation
Inventor: COLBERT MICHAEL A
IPC: B60T13/66
Filed: 1998-09-28
Abstract: Radio-based control of railroad train brakes is effected in which brake systems are computer controlled. An End of Train (EOT) system is used in which microprocessor circuits of a Locomotive Control Unit (LCU) and an EOT unit are programmed to perform these and other functions. The computer system has several states. On power on, the system enters the Setup state during which the system stores about one minutes worth of both brake pipe and equalizing reservoir pressure data. This data is later used to determine the rate of change of these pressures to determine stability. Once setup is complete, the system enters the Stability state during which operating pressures are determined. When the equalizing reservoir pressure, the brake pipe pressure and the brake pipe pressure at the end of the train are stable, the EOT unit is commanded to update operating pressures stored in its microprocessor control circuit. Once the several pressures have been found to be stable, the system goes to the Release state. The system makes transitions between the Release state and the Stability state until a predetermined decrease in brake pipe pressure is detected.      At this point, the system makes a transition to the Application state. In this state, determinations are made as to whether to transmit brake commands to the EOT unit from the LCU or to return to one of the Stability or Release states. In any of these states, the system can immediately enter the Emergency state to the Setup state, if setup has not been completed, or to the Release state if setup has been completed.

Abstract: The invention relates to a plug-in circuit breaker and has the object of preventing no-load discharges of the closing mechanism when extraction of the circuit breaker is performed. The drive mechanism (40) of the loading and closing mechanism (30) of the circuit breaker (1) comprises a trip mechanism (60) which is able to move from a closed state wherein actuation of an oscillating lever (45) is designed to move the closing spring (34) to its loaded state, to a tripped state wherein actuation of the oscillating lever is designed not to move the closing spring (34) to its loaded state. This trip mechanism causes either disengagement of the oscillating lever or neutralization of a free-wheel coupling of the drive mechanism. The circuit breaker is moreover equipped with opening and closing controls causing an opening, closing, opening (OCO) cycle when extraction is performed.

Abstract: It is an object of the present invention to prevent forced oxidation of dust in copper flash-smelting works, reduce the adhesion of dust to boiler the water tube, and improve the on-line ratio and productivity index.      The temperature at the WHB radiation section outlet is greatly reduced and the atmosphere within the WHB radiation section is controlled by blowing a mixed gas of nitrogen gas and air from the feed aperture 6 established in the wall into the boiler radiation section 2 of the waste heat boiler of the flash-smelting furnace in a copper flash-smelting works. As a result, a reduced amount of dust is generated. Moreover, the dust removed from the off-gas has reduced adhesion, the exhaust gas having been generated within the flash-smelting furnace 1 and sent to the sulfuric acid works via the boiler radiation section 2, boiler furnace outlet 8, boiler convection section 3, cyclone 4, and electrostatic precipitator.
