Patent CA-2637306-A1 (CA)
Title: Gas detector
Inventor: TULIP JOHN
IPC: G01J3/42
Filed: 1996-08-16
Abstract: A gas detector of gas in a target zone has a transmitter of frequency modulated light and a receiver. In the receiver, a homodyne detection circuit mixes a detected signal with a reference signal at one of the modulation frequencies, where the reference signal has been derived from light that has passed through the target zone. The homodyne detection circuit includes a bandpass filter, amplifier, phase lock loop and phase shifter. Etalon fringes are reduced by moving them to high frequencies and filtering them out. Gas density is measured by comparison of the detected signal from the target zone with a signal from a gas reference cell. A method of detecting gas includes transmitting frequency modulated light through a target zone, receiving the light, and homodyne detection of the detected signal by mixing the detected signal with a reference signal at one of the modulation frequencies, where the reference signal has been derived from light that has passed through the target zone. Light from a laser transmitter propagates along several optical light guides from a laser transmitter to a laser receiver. The optical light guides form a guided light path traversing each of several target zones where unwanted gas may be present. An optical switch permits selection of one of the paths and hence one of the target zones for the detection of gas. A preferred light guide uses optical fibers with optical switches, or a combination of a splitter and a switch. A lens system provides for the collection of light from a transmitting fiber optic and receiving fiber optic. The gas detector is provided with means to eliminate phase sensitivity of the detector. Also, a gas detector for detecting a target gas in multiple target zones. A light collector receives light from the first scanning optical element that has returned from the multiple target zones and directs the light towards the receiver. A controller controls the position of the first scanning optical element and thereby controls which of the target zones is traversed by light from the laser transmitter.

Inventor: WOJAK BOGDAN
IPC: C01B32/40
Filed: 2008-09-24
Abstract: A gas turbine topping device, which is disposed upstream of a steam-raising section, is used for generating power in the manufacture of sulphuric acid. A sulfur-burning combustor generates hot sulfur dioxide while a pressure-exchanging ejector mixes the hot combustion gases with a cooler gas (e.g. pressurized air, pressurized N2 or recycled sulfur dioxide (SO2) to form a mixed working gas having a temperature below the maximum allowable temperature (metallurgical limit) of the blades of the turbine. The turbine drives an oxygen compressor which supplies oxygen to a bubbling chamber which also receives S8 to produce sulfur vapor for combustion. By using stoichiometric quantities, sulfur dioxide is delivered in requisite quantities to a sulfuric acid plant without any harmful emissions.  Useful amounts of electrical power can thus be generated by the gas turbine topping device as well as the downstream steam turbine by harnessing the enormous amount of waste heat involved in the manufacture of sulfuric acid.

Abstract: A retractable covering for an architectural opening is reversibly driven through an input assembly, a transmission and an output assembly by a reciprocal operating cord that can be pulled down by an operator and will automatically retract while the covering is held in a predetermined position. While the input assembly is always driven in a first direction, a transmission is shifted between two operative positions through movement of a shift arm depending upon the positioning of the shift arm by the operating cord. The shift arm is pivotal about an axis parallel with a roller for the covering and when the operating cord is pulled straight downwardly, the covering is moved in an upwardly or retracting direction while if the operating cord is pulled downwardly and toward the operator, i.e. away from the architectural opening, the covering is driven in a downwardly or extending direction.

Title: Three phase and polarity encoded serial interface
Inventor: WILEY GEORGE A
IPC: H04L5/20
Filed: 2008-02-29
Abstract: A high speed serial interface is provided. In one aspect, the high speed serial interface uses three phase modulation for jointly encoding data and clock information. Accordingly, the need for de-skewing circuitry at the receiving end of the interface is eliminated, resulting in reduced link start-up time and improved link efficiency and power consumption. In one embodiment, the high speed serial interface uses fewer signal conductors than conventional systems having separate conductors for data and clock information. In another embodiment, the serial interface allows for data to be transmitted at any speed without the receiving end having prior knowledge of the transmission data rate. In another aspect, the high speed serial interface uses polarity encoded three phase modulation for jointly encoding data and clock information. This further increases the link capacity of the serial interface by allowing for more than one bit to be transmitted in any single baud interval.
