摘要:
An air intake filter for internal combustion engines designed to prevent the escape of fuel fumes to the atmosphere, the filter cartridge including a rectangular block-shaped filter body folded of filter paper with horizontal top and bottom fold edges, the fold cavities on the downstream side of the cartridge being filled with activated carbon which is retained by a cover layer of fiber fleece. The outer edges of the filter body and of the cover layer are embedded in a resilient sealing collar. The longitudinal extremities of the fold cavities are closed by fold pockets.
摘要:
A method of removing soot from the exhaust gases of internal combustion engines, especially of the diesel-type, using an exhaust filter which collects the soot and a dosing device which, when triggered by a pressure switch and a series-connected temperature switch, injects a dose of a combustion-inducing substance onto the soot layer with the aid of compressed air. The combustion-inducing substance consists of CuCl and NH.sub.4 NO.sub.3 which are stored as a mixture in a single container or as separate ingredients in two containers.
摘要:
A method and device for removing soot from the exhaust gases of a diesel-type internal combustion engine, using a soot filter in the exhaust line and a dosing device which injects a dose of a combustion-inducing substance, for example CuCl, into the soot filter by means of compressed air. The soot-combusting process is initiated automatically, in response to a critical exhaust pressure level and the simultaneous presence of a suitable temperature in the soot filter, using a pressure switch and a series-connected thermal switch. Compressed air, flowing through a bypass line, scavenges the supply line of the combustion-inducing substance, while supplying additional oxygen for the soot combustion process.

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. Said sensor comprises a capacitor and an evaluation electronic system. The variation of the capacity of the capacitor, which is caused by the medium, can be measured. Said 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.

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. In order to prevent or reduce soot and graphite deposits in the step without increasing the nitrogen oxide content in the furnace waste gases, a secondary oxidation gas is blown into step during the firing phase of each port neck in addition to the primary oxidation gas preheated in the regenerators that flows over the step. If significant deposits of carbon material and/or temperature problems occur, then in a similar way an oxidation gas can be blown in during the exhaust phase for the furnace waste gases of each port neck when the secondary burner is switched off.

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. To enable this procedure, the empty can to be delivered to the filling station is temporarily moved with increased speed, and the spatial interval between the empty can to be delivered to the filling station and the full can which is leaving the filling station is reduced.
摘要:
A hollow floor composed of a profiled false floor (1) which is arranged between a top floor (2) and a sub floor (3) and is designed to be plate-shaped, the false floor (1) having cup-shaped depressions (4) that are joined together by essentially flat edge areas (5). The depressions (4) are filled in with a sound-deadening filler material (6).
摘要:
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.
摘要:
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.
摘要:
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.
