Patent CA-2261454-C (CA)
Inventor: JOSHI MAHENDRA L
IPC: F23M5/02
Filed: 1999-02-11
Granted: 2008-10-07
Abstract: Burner firing method and device are presented where an oxidizing oxygen--fuel burner is fired at an angle to the reducing air-fuel burner flame to reduce overall NOx emissions from high temperature furnaces. The oxidizing oxy-fuel burner stoichiometric equivalence ratio (oxygen/fuel) is maintained in the range of about 1.5 to about 12.5. The reducing air-fuel burner is fired at an equivalence ratio of 0.6 to 1.00 to reduce the availability of oxygen in the flame and reducing NOx emissions.  The oxidizing flame from the oxy-fuel burner is oriented such that the oxidizing flame gas stream intersects the reducing air-fuel flame gas stream at or near the tail section of the air-fuel flame. The inventive methods improve furnace temperature control and thermal efficiency by eliminating some nitrogen and provide an effective burnout of CO and other hydrocarbons using the higher mixing ability of the oxidizing flame combustion products. The simultaneous air-fuel and oxy-fuel burner firing can reduce NOx emissions anywhere from 30% to 70% depending on the air-fuel burner stoichiometric ratio.

Granted: 2004-08-10
Abstract: A method for determining whether a subject has had a stroke and, if so, the type of stroke which includes analyzing the subject's body fluid for at least four selected markers of stroke, namely, myelin basic protein, S100 protein, neuronal specific enolase and a brain endothelial membrane protein such as thrombomodulin or a similar molecule. The data obtained from the analyses provide information as to the type of stroke, the onset of occurrence and the extent of brain damage and allow a physician to determine quickly the type of treatment required by the subject.

Title: A device for control of discharge and disengagement of an energy storage device when extraction of a plug-in circuit breaker is performed
Inventor: PINERO ERIC
IPC: H02B11/133
Filed: 1999-04-12
Granted: 2008-06-17
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: A method is provided for operating a quarry area having a layer of rock covered by a layer of overburden. The area is first divided into a plurality of strips with overburden from a selected first strip being stripped by depositing the overburden adjacent respective sides of the strip. The layer of rock from the first strip is stripped, blasted and excavated in sections for minimising the collection of water within a given work area. When stripping sections of adjacent strips, the overburden is deposited in the previously excavated strip or previously excavated section of the strip in a manner so as to cover an open rock face of the stripped section before blasting. Covering the rock face contains the rock to be blasted within a given section of the quarry area. Excavating equipment is supported above the rock layer for working below the water table if required. Depositing overburden in previously excavated strips and sections minimises displacement of overburden about the quarry area while maximising the accessible rock of the quarry area.
