Abstract: An exemplary seal arrangement includes a labyrinth seal (1). The seal is in operative engagement with a shaft (2) that extends in an opening (3) in a wall (4) bounding a riddlings hopper (13). The exemplary shaft moves along at least one radial direction on an orbital or eccentric path within the wall opening so as to suitably cause movement of at least one grate step of a firing grate. First seal discs (5) extend radially relative to the shaft axis and are in fixed operative connection with the shaft. Second seal discs (6) also extend radially and are in fixed operative connection with a seal housing (8) that is attached to the wall. Throughout shaft movement within the opening, first seal discs continuously extend intermediate and in radially overlapping relation with second seal discs, and second seal discs continuously extend intermediate and in radially overlapping relation with first seal discs.

Abstract: Exemplary arrangements relate to a method for incinerating waste on a combustion grate of a furnace and an apparatus for carrying out such a method. Oxygen mixed with carrier gas is supplied to the combustion for incineration as an oxygen and carrier gas mixture. The carrier gas comprises recirculated combustion gas from the furnace and may have a CO2 concentration of from 10% to 99%.

Abstract: A nozzle (1) is configured to deliver gas into an incinerator such as a waste incinerator (3). The nozzle includes a nozzle pipe (20) and a swirl generator (21). The swirl generator includes a plurality of angularly spaced vanes (24) that are attached to an inner surface (19) of the pipe. The vanes terminate radially inwardly at respective vane inner surfaces (36). A continuous central passage (25) extends axially between the vane inner surfaces. Utilization of the swirl nozzles in connection with an incinerator provide improved gas mixing and avoid having regions with insufficient air to achieve complete combustion.

Abstract: A laser cutting system has a specially designed frame that allows the laser cutting head to be mounted to the underside of a cross beam for a more efficient movement. The frame is further designed so as to allow the accessing of the work area of the laser cutting system along three different directions. The movement of the laser cutting head for fabricating a sheet placed in the work area of the laser cutting system is effected by a process that takes into consideration a number of parameters and determined data all of which are interpolated for generating optimal movements to further enhance the operating efficiency of the laser cutting system. The laser resonator of the laser cutting system of the instant invention is configured to have a telescopic system that maintains the density and power of the laser beam by auto focusing the same so that optimum cuts can be effected irrespective of whichever area of the worksheet is to be fabricated.

Abstract: In order to create a process for producing muffler inserts as well as novel muffler inserts, which are most optimally adaptable in size and shape to the interior space of the muffler housing to be filled, by simple means, and which also can be produced economically and have improved effect, a process is proposed for producing muffler inserts which operate entirely or partially according to the absorption principle, whereby a predetermined amount of a loose bundle of individual elements of a suitable sound-absorbing material is formed, the loose bundle is shaped roughly in an assembly shaping unit corresponding to the intended shape of the muffler insert, and whereby the loose bundle is fixed into a shaped composite in the shape corresponding to the assembly shaping unit, in such a way that the fixed shape can be handled without individual elements loosening until assembly for the specified uses of the muffler insert; however during the specific use as a muffler insert the fixing is at least partially released

Abstract: A combination punch press and laser machine has its punch press system and worktable mounted to one frame while its laser system mounted to another frame. The two frames are not in contact with each other, but are positioned such that a cantilever member of the frame whereon the laser system is mounted extends over the worktable so that the laser cutting head which is mounted to the end of the cantilever member superposes over a particular location of the worktable whereat the cutting of the worksheet by the laser beam is to be effected. This particular laser cutting location is positioned relative to the location of the worktable whereat the punching of the worksheet is to be effected by the pair of coacting upper tool and lower die of the punch press system.
