20090239182 | COMBUSTION METHOD WITH CYCLIC SUPPLY OF OXIDANT - The invention concerns a combustion method for industrial furnace comprising an arrangement of two substantially parallel and symmetrical burner assemblies (G, D). Each burner assembly comprises a fuel injector (10G, 10D) and three oxidant injectors (1G, 2G, 3G, 1D, 2D, 3D) arranged at increasing distances from the fuel injector. An oxidant supply system cyclically distributes a specific flow of oxidant among some at least of the second and third injectors of the burner assemblies (2G, 3G, 2D, 3D). The amount of nitrogen monoxide produced upon combustion is thus reduced, while ensuring a good distribution of the heating power in the furnace. | 09-24-2009 |

20120009531 | DISTRIBUTED COMBUSTION PROCESS AND BURNER - During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved. | 01-12-2012 |

20100252290 | ADJUSTABLE AMPLITUDE HAMMER DRILL MECHANISM - An adjustable amplitude hammer drill mechanism comprises a main shaft having a forward drill chuck end portion and a rearward shank portion, and defining a longitudinal axis. An impact receiving member is mounted in fixed relation on the main shaft for rotation therewith. A selectively operable longitudinal-hammer member is mounted on the main shaft for free rotation of the main shaft with respect to the longitudinal-hammer member and for operative engagement with the impact receiving member. Rotation of the main shaft and impact receiving member about the longitudinal axis when the longitudinal-hammer member is in force transmitting engagement with the impact receiving member, causes the longitudinal-hammer member to move in a reciprocating motion between the forwardly displaced position and the rearwardly displaced position, and transmits impact forces forwardly along the longitudinal axis to the main shaft. There is also an amplitude adjustment assembly for mounting the selectively operable longitudinal-hammer member in the operative engagement with the impact receiving member. | 10-07-2010 |
20100276169 | IMPACT MECHANISM - An impact mechanism for use with a drive motor comprises a drive engaging member and a tool bit retaining member operatively inter-connected with the drive engaging member. The tool bit retaining member has a main body portion, and an anvil portion and a tool bit retaining portion each securely attached thereto for co-rotation therewith. A hammer is mounted on one of the drive engaging member for guided movement between an anvil contact position whereat force is transmitted from the hammer to the anvil portion so as to create a moment about the longitudinal axis, and a release position whereat the hammer is temporarily removed from the anvil portion. A spring biases the hammer to the anvil contact position. A selectively adjustable spring compression mechanism permits selective compression of the spring. In use, rotation of the drive engaging member about its longitudinal axis causes the hammer to move from its anvil contact position towards its release position, thereby storing potential energy in the spring. When the hammer reaches the release position, the hammer is forcefully propelled by the spring and the rotation of the drive engaging member to impact on the anvil portion, thus urging the tool bit retaining member to forcefully rotate about the longitudinal axis. | 11-04-2010 |
