Abstract: An electrical property sensor is presented that includes a printed circuit board with a first face separated from a second face by a thickness, the first face having a length and a width. The sensor also includes an aperture extending from a first face of the printed circuit board to a second face of the printed circuit board. The aperture includes a receiving electrode and a transmitting electrode. When a fluid flows through the aperture and a voltage is provided at the transmitting electrode, a cunent flow is measured at the receiving electrode.

Abstract: Mat (1) for mounting a pollution control element in a housing, comprising inorganic fibre material. At an edge surface (20) of the mat a plurality of fibres (30) are heat fused to form fusion volumes (90). The average number of fusion volumes per square millimetre of the edge surface is at least 100, and at least 80% of the fusion volumes have a projected size of between 10 μm and 100 μm.

Abstract: Sensored mixer, comprising a mixing device for mixing two or more components to produce a mixed liquid at a mixer output, and a property sensor for determining a property of a liquid, the property sensor comprising a) a channel comprising a sensing zone through which the liquid flows; b) two electrodes for generating an electric field of one or more sensing frequencies in the sensing zone; c) a data storage device comprising a pre-stored set of calibration data representing calibration impedance responses measured previously at the one or more sensing frequencies and at different property values of the property of an identical liquid; and d) a device to repeatedly i) generate between the electrodes an electric field of in the sensing zone; ii) sense between the electrodes, a response impedance; iii) derive from the response impedance a property value of the property of the liquid, using the pre-stored set of calibration data representing calibration impedance responses, wherein the property sensor is in fluid communication with the mixer output such that the mixed liquid can flow from the mixer output through the sensing zone. A method for sensing a property of the liquid and a data set of calibration data representing calibration impedance responses usable with the sensor and the method are also disclosed.

Abstract: A system for forming an abrasive article is presented. The system includes a workspace and an abrasive material dispenser that deposits a layer of abrasive material onto the workspace. The system also includes a leveler that levels a surface of abrasive material on the workspace. The system also includes a binder jet printer that dispenses a liquid binder onto the layer of abrasive material. The workspace is on a moving surface that moves the workspace between a dispensing position under the dispenser, a leveling position under the leveler, and a printing position, under the printer.
