20080236118 | Exhaust particulate filter for a machine engine system and assembly method therefor - An exhaust particulate filter for an engine system includes a housing having an inlet, an outlet and a shell shaped to fit the particulate filter within a predefined spatial envelope. Filter elements arranged in a bundle and having a packing arrangement are positioned within the housing. Each of the filter elements includes a perforated tube wrapped with fibrous metallic filter media. The bundle defines a perimetric line at least partially matched to the shape of the shell. An assembly method for a particulate filter includes arranging filter elements in a packing structure within a bundle, the bundle having peripherally located filter elements and internally located filter elements. The filter elements each include a perforated tube wrapped with fibrous metallic filter media. The assembly method further includes positioning the bundle of filter elements within a housing having a shape at least partially matched to a shape of the bundle. A unique method of joining various of the components via swagging is also disclosed. Clamping of the filter media, and joints between filter element and support plates, may be achieved via swagging, for example. | 10-02-2008 |
20080236119 | Exhaust gas particulate filter for a machine and filter cartridge therefor - An exhaust particulate filter for an engine system includes a housing having an inlet, an outlet and a shell shaped to fit the particulate filter within a predefined spatial envelope. Filter elements are arranged in a composite filter assembly and are packed within a housing. Each of the filter elements includes a cartridge having a frame wrapped with fibrous metallic filter media. The composite filter assembly has a shape corresponding to the shape of the shell. Each cartridge of the composite filter assembly is reversibly coupled with a frame internal of the shell via trapping elements having a release state and a trapping state. | 10-02-2008 |
20090079256 | ROTARY CUTTER FOR TUNNEL BORING MACHINE - A rotary cutter for a tunnel boring machine or similar machine has a cutter ring mounted to a hub. The hub is mounted on a shaft. A sleeve bearing system is positioned between the hub and the shaft for supporting the hub on the shaft and allowing relative rotation. A duo-cone seal assembly is positioned between the hub and the shaft to seal out contaminants from the sleeve bearing system. An oil gallery with lubricating oil for lubricating the sleeve bearing system is provided in the shaft. | 03-26-2009 |
20090133382 | Electrically regenerated exhaust particulate filter for an engine system and operating strategy therefor - An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases are distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements. | 05-28-2009 |
20090272263 | ELECTRICALLY REGENERATED EXHAUST PARTICULATE FILTER HAVING NON-AXIAL REGENERATION FLAME PROPAGATION - An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases may be distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. The filter cartridges may be cylindrical or wedge-shaped, or of a variety of other configurations. Regeneration may take place according to a non-axial regeneration propagation profile. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements. | 11-05-2009 |
20130082846 | SENSOR SYSTEM AND METHOD - A method is disclosed for collecting information related to a machine component of a mobile machine that is configured to perform work on a worksite. The sensor system may be installed on or within the machine component, and the machine component may be installed with the sensor system on the mobile machine. The information may be collected with the sensor system while the machine is performing work on the worksite, the information relating to a characteristic experienced by the machine component. The information may be transmitted with the sensor system. The sensor system may collect information related to a tracked undercarriage of the mobile machine, or the cutting head of a tunnel boring machine. | 04-04-2013 |
