A carton pulling assembly pulls a partially formed carton from a mandrel on a form, fill and seal packaging machine. The machine has a vacuum source for providing a vacuum and includes a machine controller. The partially formed carton has a sealed bottom wall. The carton pulling assembly includes a carton puller element movable in a reciprocating manner toward and away from the mandrel. A vacuum head assembly is mounted to the carton puller element for reciprocating movement therewith. The vacuum head assembly includes a cylinder and a finger configured for reciprocating movement within the cylinder having a suction element mounted thereto. The finger has a vacuum channel for communicating vacuum from the cylinder to the suction element. The finger is movable between an extended position in which the suction element contacts and engages the partially formed carton sealed bottom wall and a retracted position in which the reciprocating finger pulls the carton from the mandrel. The reciprocating finger moves toward the extended position by application of the vacuum to the vacuum head assembly while communicating vacuum to the suction element. A method for pulling a partially formed carton from a mandrel is also disclosed.

In a motorcycle in which a main seat, a fuel tank, and an engine are supported by a vehicle body frame, a center cover is disposed so as to be laid across a pair of left and right pipe support members. A fuel pump and an ignition coil are supported by and positioned on the center cover. The aforementioned arrangement provides support for auxiliary equipment for the engine without the necessity of using a special supporting member and without impairing the layout of members, such as a battery case in the vicinity of the engine.

A pulverized coal burner includes a venturi for contracting a flow of a mixture of pulverized coal and primary air toward a central axis of a fuel nozzle 2. A spindle having a cone is provided coaxially with the central axis and gradually expands from an upstream side to a downstream side to cause the mixture to impinge thereon and diffuse. A column extends from the cone and is parallel to the central axis of the fuel nozzle, and a cone extends from the column and gradually narrows from an upstream side to a downstream side. A flow path divider, having a cone gradually narrowing coaxially with the central axis on the downstream side of the spindle, and a cylinder extending from the cone and being coaxial and parallel with the central axis of the fuel nozzle 2, coaxially divides the flow path.

A pulverized coal combustion burner includes a pulverized coal nozzle, and secondary and tertiary air nozzles provided in concentric relation to the pulverized coal nozzle. A flame stabilizing ring is provided at an outlet end of the pulverized coal nozzle. A separation wall is provided within the pulverized coal nozzle to divide a passage in this nozzle into two passages. A pulverized coal/air mixture flows straight through the two passages, so that recirculation flows of the pulverized coal/air mixture are formed in proximity to the outlet end of the pulverized coal nozzle. As a result, the ignitability of the pulverized coal, as well as a combustion rate, is enhanced, thereby reducing the amount of discharge of NOx.

A gas turbine combustor is capable of reducing NOx over a whole load range of a gas turbine. The combustor comprises two burner systems. It is possible to independently control a flow rate of combustion air supplied to a burner of the respective systems and a flow rate of bypass air jetted from through a bypass air port. The air supplied to the burners is mixed with fuel in a mixing chamber and then ejected into a combustion chamber so as to form a flame. The amount of bypass air is controlled in accordance with an operation load, a humidity of air and a heating value of fuel. It is therefore possible to prevent any blow off and reduce NOx over the whole load range of the gas turbine.

A low-NOx boiler comprises a burner for burning gaseous fuel, heat transfer pipes heating water by combustion heat of the burner to generate steam and having a passage through which water flows, a steam drum communicating with the heat transfer pipe and accumulating the steam from the heat transfer pipe, and an exhaust gas duct located in the furnace to exhaust combustion gas generated by combustion of gaseous fuel outside of the boiler. The boiler further comprises unburnt gas burner in the exhaust gas duct for burning unburnt content in the combustion gas flowing in the duct. The unburnt gas burner includes a nozzle for injecting premixture flow of fuel and combustion air and flame holding plate located near the downstream side of the outlet of the nozzle to interrupt the premixture flow to form a circulating flow on downstream side of the flame holding plate. As gaseous fuel and air are mixed in advance and a flame is formed, the flame length can be shortened. Furthermore, the flame holding plate enables to reduce NOx generated. Unburnt gas burner provided in the exhaust gas duct makes it possible to notably reduce the concentration of NOx discharged to the outside of the system.

An optical disc (10) includes a substrate (11), which is formed from either a resin-impregnated paper produced by impregnating a paper with a resin, or a resin-coated paper produced by coating a surface of a paper with a resin, and a recording layer (13), wherein the resin contains at least one resin selected from the group consisting of polycarbonates, bisphenol A epoxy resins, copolymers of methyl methacrylate and styrene, and copolymers of acrylonitrile and styrene. Furthermore, a method of manufacturing an optical disc (20) includes: providing a recording layer sheet by forming tracks on a recording base material; and bonding the recording layer sheet to a resin-impregnated paper or a resin-coated paper, thereby providing a recording layer (13) formed from the recording layer sheet on the substrate (11).
摘要:
The invention provides a combustion apparatus which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a combustion apparatus provided with a burner burning a fuel within a furnace in a theoretical air ratio or less, and an air port supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region. Further, the invention provides a wind box which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a wind box having an air port arranged in a back flow side of the burner and supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region.
