Abstract: A burner holder for a burner lance in a glass melting plant. To easily and quickly change the burner lance angle to influence the process conditions in the glass melting plant, the burner holder has a retaining unit for securing the burner lance and a sealing plate with a passage. The sealing plate is configured to secure to the glass melting plant and is provided with a recess for receiving a burner lance head. The recess forms at least one part of a passage through the sealing plate. The retaining unit is connected to the sealing plate via at least one first pivot bearing, such that the retaining unit can be pivoted or swiveled about a first axis of rotation. The pivot bearing is attached or embedded directly on the sealing plate or is connected to the sealing plate via a support arm arranged on the sealing plate.

Abstract: A glass melting installation and a method of operation of this with a melting tank, with burners for fossil fuels and with at least one regenerator for preheating oxidation gases, whereby between the at least one regenerator and the melting tank at least two step-free port necks are provided for the alternating supply of oxidation gases and the removal of combustion gases, and whereby the port necks are provided with lateral supply openings for the supply of secondary oxidation gases. In order to achieve injection into the waste gas flow without directional influence, with a simple construction and good energy usage, the supply openings for the supply of secondary oxidation gases are perpendicular to the free cross-section of the port necks above the step-free bottom surfaces.

Abstract: The invention relates to a sensor which uses the capacitive measuring principle which is used to detect the proximity of a dielectric medium, preferably for detecting a human body part, which is used in an anti-pinching system. The sensor includes a capacitor and an evaluation electronic system. The variation of the capacity of the capacitor, which is caused by the medium, can be measured. The capacitor, which can establish a distinction between a human body part or a solid and water and/or humidity, is characterized in that the capacitor can be operated in a successive manner by at least two different frequencies and/or at least two different pulse duty factors by using the different ratio of said elements in a variable electric field. The invention also relates to a corresponding method.

Abstract: During the heating of glass melting furnaces having a combustion chamber with regenerators for preheating oxidation gases, with port necks that open into the combustion chamber, with primary burners and with secondary burners that are installed in a cascade arrangement relative to the primary burners, the secondary burners are operated as cascade burners with a relatively low proportion of the fuel, the secondary fuel. Flames are thereby created in over- and sub-stoichiometric conditions and the flame gases formed are mixed with one another so that the complete combustion process in the combustion chamber is more or less stoichiometric. The secondary fuel is supplied by the secondary burners to a step, installed in the port neck.

Abstract: A stretched fiber band is deposited in a can, located in the filling station of a can exchanger of a draw frame, by means of a turntable. The rotational axis of the turntable exhibits an equal to or less than distance from the rotational axis of the can exchanger than the distance from the center point of the can found in the filling station to the rotational axis of the exchanger. Upon the substitution of the filled can by an empty can held in a ready-state position, the operation of the can exchanger on the rotation of the turntable is designed in such a manner, that the fiber band is deposited into the full can exiting the filling station, until this can leaves the zone of the turntable. The fiber band is then deposited into the empty can which has been brought into the filling station II, as soon as this empty can reaches the zone of the turntable.

Abstract: A spinning machine for the doubling or stretching of fiber bands with a rolling section having lower rolls which are secured in journal blocks, and wherein the upper rolls may be also secured on said journal blocks with pressure means for the loading of said upper rolls, it is proposed that the pivoting axis of the pressure arm for the placement of the pressure means to the upper rolls be arranged in such a way that, when observed in the running direction of the fiber band, said axis lies behind the rolling section. Advantageously, what is achieved thereby, is that the spinning machine can be maintained in a considerably simpler and quicker manner. Following the upward pivoting of the pressure arm, the entire area of the rolling section becomes freely accessible. The pivoting geometry of the pressure arm can be so varied, that the upper rolls can be easily restored into the guides on the journal blocks of the lower rolls.

Abstract: A method of operating a regenerative glass melting furnace with end-firing or cross-firing utilizes burners to provide sub-stoichiometric combustion and super-stoichiometric combustion along the sidewalls or transverse walls of the furnace and equipment associated with the method. Fuel supply is controlled so that overall combustion is stoichiometric.

Abstract: A filter device with a preferably hollow-cylindrical, pleated filter element which is arranged concentrically around a cylinder axis and through which a medium to be filtered passes. Seals are necessary on the filter device so that the medium to be filtered will not be able to leak out and so that the filter element, which typically is constructed of filter paper, must be fixed in place together with its pleats. Advantageously, an elastic composition can be disposed as a seal on at least one of the ends of the filter element, and after curing the elastic composition will fix the pleats of the filter element and will have sufficient residual elasticity to seal the filter element with respect to a central mounting tube on which it is to be mounted.

Abstract: A filter having a filter element disposed in a filter housing; the filter element being formed of a pleated filter paper or a nonwoven filter material and being of substantially planar or flat configuration. Sealing elements in the form of a rolled seal are provided on at least two lateral surfaces of the filter in order to seal the filter element in the filter housing.

The perforated mixer is situated inside the mixing tube at the end of the inspiration tube.

Abstract: The invention relates to a process for the discontinuous burning off of carbon deposited on the heat-resistant exhaust gas filter of an internal combustion engine, particularly a diesel internal combustion engine. At least one metal must be present during this process. The problem of ensuring the combustion of the carbon at the minimum temperature and of achieving a long filter life, is solved in a particularly advantageous manner through the use of an organic complexing agent able to form a complex with the metal and/or an organo-metallic complex compound of the metal with the organic complexing agent.The invention also relates to an apparatus for performing the inventive process. For this purpose, the exhaust gas filter preferably has at least two, at least temporarily separately operable filter units.
