Granted: 2008-09-09
Abstract: A burner apparatus and method for the combustion of a fuel and an oxidizer includes a burner block (7) having a fuel line (1) for feeding fuel to a fuel port opening (12) into a combustion chamber and a plurality of oxidizer lines (32, 33, 34) positioned around the fuel line (1) for feeding an oxidizer to oxidizer ports (17, 18, 19, 20) to the combustion chamber for combustion with the fuel from the fuel port (12). The oxidizer lines and ports (13, 14, 15, 16 and 17, 18, 19, 20) are spaced around the fuel port (12) so that controlling the oxidizer is used to change the position and shape of the flame in the combustion chamber. Oxidizer control valves (36, 37, 38, 39) vary the amount of oxidizer fed through the oxidizer line so that the oxidizer control valves (36, 37, 38, 39) for each set of oxidizer lines are spaced around the fuel port (12) to allow both the position and shape of the burner flame to be controlled.

Abstract: A module for a modular conveyor mat. Viewed in a conveying direction, the module comprises a front side and a rear side having hinge loops extending outwards relative to the module. The hinge loops are such that in two modules succeeding each other in the conveying direction, the hinge loops on the front side of one module can cooperate with the hinge loops on the rear side of the other module and that the hinge loops can be coupled by means of hinge pins extending transversely to the conveying direction. The module further comprises a top side, a bottom side and two lateral sides located opposite each other transversely to the conveying direction. The module comprises a recess accommodating a retaining member, and a closing part of the retaining member is rotatable between a first position in which the closing part can retain a hinge pin received by the hinge loops transversely to the conveying direction and a second position in which the closing part can release a hinge pin received by the hinge loops transversely to the conveying direction. Both in said first and second position of the closing part and in intermediate positions of the closing part, the retaining member is located within boundary faces formed by the top side and the bottom side of the module. The retaining member is connected to the module such that loss of the retaining member is prevented.

Abstract: In an arrangement for the controlled cooling of hot-briquetted direct-reduced sponge iron in the form of an apron conveyor consisting of individual plates and located in a tank, the individual plate is designed as a conveyer trough, wherein at least one sliding plate each is located on the two opposed longitudinal outsides and the conveyor troughs are movably supported by means of the sliding plates on slideways and connected by means of at least one chain. The invention allows to separate the drive and the bearing as the conveyor troughs are supported by means of sliding plates and the drive acts directly on the conveyor trough by means of at least one chain. As the translation elements are designed as sliding plates and slideways, the surface pressure is reduced to less than a hundredth compared to wheels running on rails and the wear of the translation elements is thus reduced.

Title: Carbon monoxide reducing device and carbon monoxide reducing method
Inventor: ARAKI YASUSHI
IPC: C01B3/58
Filed: 1999-09-16
Granted: 2003-03-25
Abstract: A carbon monoxide reducing device supplies oxygen to a reformate gas obtained through a reforming reaction so as to oxidize carbon monoxide contained in the reformate gas by means of the oxygen and thereby reduces a concentration of carbon monoxide contained in the reformate gas. This carbon monoxide reducing device is equipped with an oxygen supply amount controller designed to oxidize CO. The oxygen supply amount controller controls an amount of oxygen supplied to oxidize carbon monoxide contained in the reformate gas based on an amount of supply of fuel contributing to the reforming reaction. Thereby, the amount of oxygen for oxidizing carbon monoxide contained in the reformate gas is adjusted appropriately, and a high-quality reformate gas can be obtained.

Title: Turbine engine with a thermal valve
Inventor: PATEL KIRITKUMAR
IPC: F01D3/04
Filed: 1998-12-04
Granted: 2008-01-15
Abstract: A turbine engine having interior cavity (73) sealed by a thermally controlled valve (80) is disclosed. The cavity (73) is defined by at least one cylindrical wall portion (74). The valve comprises an opening (82) in the cylindrical wall portion and a cylindrical band (83), coaxial and interior to the wall portion. The cylindrical (83) band is made of material having a higher thermal coefficient of expansion than the wall portion. As the temperature of the engine increases, the band (83) expands at a higher rate than the wall (74), thereby sealing the valve. As the temperature decreases, the band contracts thereby opening the valve. The valve may be used to permit a cavity to be pressurized at low temperatures. The pressure in the cavity may exert a forward load on a thrust bearing, suspending the engine shaft.
