20090239182COMBUSTION 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
20100257899Oven and Oxy-Combustible Method for Melting Vitrifiable Materials - The invention relates to a method for melting vitrifiable materials in a low-capacity oven, wherein at least part of the melting energy is supplied by two oxy-burners projecting into the melting chamber through the upstream wall and arranged on opposite sides of a vertical plane in which a longitudinal axis of the melting chamber is situated, in such a way as to create two flames, the respective injection axes thereof crossing at a distance from the upstream wall, between ⅓ and ¾ of the length L of the melting chamber.10-14-2010
20110195367Burner Assembly with Enhanced Flexibility - The invention relates to a burner assembly with enhanced flexibility, comprising a plurality of fuel rods that can be mounted in and removed from a fuel rod passage and that are connected to a fuel supply device by a flexible line, wherein each flexible line can be individually opened and closed.08-11-2011
20120009531DISTRIBUTED 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

20110214539MULTI-BIT TOOL HAVING SPRING LOADED ACTUATION MECHANISMS AND A RIGID STRUCTURAL FRAME - A multi-bit tool comprises a housing having a bit chuck with a bit-receiving opening. A substantially rigid main frame member defines a plurality of longitudinal channels and is disposed within the housing such that each of the plurality of longitudinal channels is generally aligned along the longitudinal axis of the multi-bit tool. A plurality of spring loaded actuator mechanisms are mounted in rigidly retained relation within one channel of the frame member. Each spring loaded actuator mechanism has a carriage member movable between a rearward position and a forward position, and a trigger member movable between a rest position, a forward triggering position and a rearward triggering position. The carriage member is moved to its rearward position by movement of the trigger member to its rearward triggering position and the carriage member is moved to its forward position by movement of the trigger member to its forward triggering position. Bit assemblies having a tool bit are operatively mounted within the housing for movement by the actuator mechanism between a retracted configuration and a forwardly extended in-use configuration corresponding. Each bit assembly is operatively connected to the carriage member on a corresponding spring loaded mechanism for co-operative movement therewith.09-08-2011

A capped aperture permits the ingress of water into and the egress of water from the substantially hollow interior. A handle connector is for connecting the collapsible exercise weight to a handle. The peripheral outer wall comprises a plurality of wide diameter bellows folds and a plurality of narrow diameter bellows folds disposed alternatingly one with the other. The wide diameter bellows folds and the narrow diameter bellows folds are each movable between an expanded configuration and a collapsed configuration. The narrow diameter bellows folds at least partially fit within adjacent ones of the wide diameter bellows folds when the narrow diameter bellows folds are in the collapsed configuration.09-02-2010

20090056966IMPACT MECHANISM - “An impact mechanism comprises a drive motor engaging member and a tool bit retaining member rotatably inter-connected therewith. The tool bit retaining member has a main body portion, an anvil portion securely attached thereto for co-rotation therewith, and a tool bit retaining portion securely attached thereto for co-rotation with the main body portion. A hammer member is mounted on the drive engaging member for movement between an anvil contact position whereat force is transmitted from the hammer member to the anvil portion, and a release position whereat the hammer member is temporarily removed from the anvil portion. A spring biases the hammer member to the anvil contact position. In use, the hammer member to move from its anvil contact position towards its release position, whereat the hammer member is propelled by the spring and the rotation of the drive engaging member to impact on the anvil portion.”03-05-2009
20100252290ADJUSTABLE 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
20100276169IMPACT 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
