Abstract: A tip attachment is disclosed. The tip attachment may an attachment body including a recess to fit on or in a tip of a device during programming of a robotic device. The attachment body may be structured such that the attachment body defines a set of angles of the tip during the programming of the robotic device. The recess may be sized such that the recess defines a distance between the tip and a workpiece during the programming of the robotic device.

Abstract: A fuel injector may include a nozzle assembly and a body. The body may have a fuel inlet, a nozzle supply passage fluidly coupled to the nozzle assembly, and an internal surface defining a chamber within the body. The fuel inlet may be fluidly coupled to the nozzle supply passage via the chamber. The fuel inlet defines an inlet dimension and the chamber defines a chamber dimension, the chamber dimension being larger than the inlet dimension.

Abstract: A filter internal flaw test apparatus includes a frame with a filter support and at least one pair of transducer supports. A filter is positioned in the test apparatus, and an ultrasound through transmission test and at least one ultrasound pulse echo test are performed on the filter. Data reliability is increased by positioning the pair of transducers in alignment with one another and pushing them toward one another using a force generator with a predetermined uniform force, such as via a regulated pneumatic actuator. A signal generating/receiving device is in communication with the transducers and provides the ability for analyzing the test results to determine whether the filter has an internal flaw, such as a crack or void that would render it unsatisfactory for use as a particulate filter.

Abstract: A particulate filter and a method for reducing pollutants are provided. The particulate filter comprises at least one first piece, said first piece comprising non-linear channels, and at least one second piece adjacent to the at least one first piece. The particulate filter is configured such that either the at least one first piece or the at least one second piece comprise either sintered metal fibers or porous metallic foam. The method comprises the steps of providing a particulate filter, said filter comprising, at least one first piece, said first piece comprising non-linear channels and at least one second piece adjacent to the at least one first piece, catalyzing the particulate filter with a catalyst, passing exhaust stream through the filter, filtering at least some soot from the exhaust stream, and chemically converting at least some NOx from the exhaust stream with the catalyst.

Abstract: A catalytic converter, an exhaust system comprising a catalytic converter, and a method of manufacturing a catalytic converter are provided. The catalytic converter comprises at least one channel configured to receive gas flow and a catalyst coated on the at least one channel. In one of the disclosed embodiments, at least one channel is partially non-linear along its length.

Abstract: A chemical sensor is provided that includes a semiconductor layer, an organic chemical layer disposed on a surface of the semiconductor layer, and a heating element configured to heat the semiconductor layer.

Abstract: According to an exemplary embodiment of the present disclosure, a system for removing matter from a filtering device includes a gas pressurization assembly. An element of the assembly is removably attachable to a first orifice of the filtering device. The system also includes a vacuum source fluidly connected to a second orifice of the filtering device.
