Patent CA-2117559-C (CA)
Title: Low nox combustion system for fuel-fired heating appliances
Inventor: MULLENS LARRY R
IPC: F23D14/70
Filed: 1994-08-24
Granted: 1997-10-21
Abstract: A fuel-fired, forced air, draft induced heating furnace is provided with NOx reduction apparatus associated with a plurality of combustor tubes forming a portion of its heat exchanger structure.  In-shot type fuel burners are spaced apart from and face the open inlet ends of horizontal combustion sections of the combustor tubes.  The NOx reduction apparatus includes a plurality of metal mesh tubes having diameters substantially less than the internal diameters of the combustion tubes.  The mesh tubes are coaxially supported within the combustor tubes, adjacent their inlet ends, by elongated support members longitudinally passing through the mesh tubes and having first ends anchored to the combustor tube inlet ends, and second ends slidably resting on internal side surface portions of the combustor tubes.  During burner operation the burner flames injected into the combustor tubes are forced through the mesh tubes which operate to laterally reduce the cross-sections of the flames, increase their axial velocity through the combustor tubes, and substantially diminish the intimate contact of secondary combustion with the maximum temperature zones of the flames within the combustor tubes.

Abstract: A method and circuit for providing stability during dimming of an electrodeless high intensity metal halide discharge lamp driven by a microwave source. Light from the lamp is rapidly dimmed to a low level in a stable manner while preventing the possibility of lamp extinction. Remote optical sensing of lamp light output is coupled with power control circuitry which modifies power delivered to the lamp based on the light response to wall defined pulses of power in the output of the microwave source.      Power delivered to the lamp is increased when the rate of light drop exceeds a predetermined rate and also, is controlled based on the overall light emission intensity. As a result, stable dimming is achieved regardless of the initial conditions of the discharge.      The dimming method disclosed is more forgiving of light-source-system manufacturing tolerances than is presently available using absolute light intensity control alone when source output power is limited.

Title: Decontamination of nucleic acid amplification reactions
Inventor: FRAISER MELINDA S
IPC: C12Q1/6844
Filed: 1994-04-26
Granted: 2001-12-18
Abstract: Methods for inactivating contaminating amplicons in isothermal nucleic acid amplification reactions such as SDA, Q.beta. and 3SR. dU is incorporated into the amplicons produced by amplification in the place of thymine (T). If these amplicons contaminate a subsequent amplification reaction, they may be inactivated as templates (i.e., rendered unamplifiable) by treatment with UDG. As isothermal amplification does not involve elevated temperatures, the UDG may be inactivated during the subsequent amplification of specific target sequences by inclusion of the UDG inhibitor protein Ugi. Incorporation of dU has unexpectedly been found to enhance the amplification power of SDA as compared to conventional SDA  reactions. The methods may also be used to detect UDG activity in reagents or samples.

Abstract: The binder composition for agglomerating ore fines of the invention is a mixture of (1) a reactive calcareous component, (2) a reactive siliceous and aluminous component, and (3) a sulfate compound.  Preferably, the binder composition is comprised of 10 to 80 % by weight lime as the calcareous component, 5 to 50 % by weight fly ash as the siliceous-aluminous component and to 80 % by weight sulfate compound such as gypsum. Most preferably, the siliceous-aluminous component is a low carbon content fly having less than about 0.5 % by weight carbon content. The preferred lime component of the binder composition is either a high calcium line with greater than about 90 % by weight CaO content ora dolomitic lime. In the process for recovery of metals from ores having ore fines of the metals, the ore fines are first agglomerated by adding thereto a binder composition, the binder composition comprising about 10 to 80 % by weight lime; 10 to 80 % by weight sulfate compound and 5 to 50 % by weight siliceous-aluminous material. A leach bed is formed of the agglomerated ore and the bed is leached with a leaching agent to there-by form a leach liquor. The metal values are recovered from the leach liquor.

Inventor: NILSSON-ALMQVIST BO
IPC: F42C13/02
Filed: 1994-09-21
Granted: 2004-06-22
Abstract: The invention relates to a sensor system with a number of sensor stations for surveillance of an area intended to include an object to be protected. The sensor stations (1-4) are essentially distributed along the periphery of a circle (5). Each sensor station comprises a detector unit (11) arranged to scan the arc in an azimuth sector allocated to it in two detection fields (9,10). The time of passage T of a target which passes the two detection fields is measured and the target position is calculated on the basis of the measured time T, the target speed V missile, the angle between the detection fields .alpha. and the angle to the target .beta.. In the sensor system, the scanning is carried out from below and up towards the background of the sky. This implies that the scanning is not interfered with by the surrounding terrain and that a large IR area is obtained. The sensor system according to the invention increases the possibilities of detecting low-flying missiles and similar targets in comparison with conventional technology

Abstract: A method and apparatus for automatically and accurately monitoring the wear of a continuous conveyor chain without having to stop the chain.  The present invention provides first and second sensors fixedly spaced along the conveyor chain at a predetermined distance.  The first and second sensors generate signals corresponding to the presence and absence of successive links provided in the conveyor chain.  The generated signals are received and processed and the necessary time intervals are calculated for providing an output indicative of chain wear of any portion of the chain. Several parameters of chain wear may be calculated, including chain stretch and instantaneous chain speed. The calculated chain wear values may be compared to predetermined values previously input and stored, and if the calculated values exceed the predetermined values, an indicator means indicates that the conveyor chain should be serviced.

Title: Signal-analysis device with at least one tensioned string and a receiver
Inventor: SZALAY ANDREAS
IPC: G10H3/12
Filed: 1994-11-26
Granted: 2000-08-22
Abstract: Described is a signal-analysis device (1) with at least one tensioned string (E1, H2, G3, D4, A5, E6) whose oscillating length can be varied by pressing the string against at least one tie-bar, the device also having a receiver (2) and an evaluation unit (3 to 9) connected to the receiver. The aim of the invention is to provide a guitar synthesizer which provides the desired note data relatively rapidly after stimulation of the string. This is achieved by vertue of the fact that the evaluation unit (3 to 9) detects pulses or pulse groups which, following stimulation of the string (E1, H2, G3, D4, A5, E6), pass along the string past the receiver (2), the evaluation unit generating from the sequence of pulses or pulse groups a signal which represents a note.
