A respirator apparatus comprising: a respirator body; a filter cartridge receiver integral with and extending from the respirator body; and a filter cartridge comprising a nozzle element integral with the filter cartridge. The respirator body and the filter cartridge are configured to be fluidically coupled through sleeve-fit engagement between the filter cartridge receiver and the nozzle element, in which one of the filter cartridge receiver and the nozzle element slides into a channel defined by the other, the filter cartridge receiver and the nozzle element defining an airflow channel. The apparatus further comprising a cantilever latch configured to secure the filter cartridge nozzle element to the filter cartridge receiver, the cantilever latch being integral with the filter cartridge receiver or with the respirator body, and the cantilever latch comprising a push button protrusion configured to detach the filter cartridge from a respirator apparatus.

Nozzle assembly (20) for a spray gun comprising:a) a tubular nozzle tube (66) having:i) a nozzle tube passage (58) extending between a nozzle tube inlet (57) and a plurality of nozzle tube outlets (52), through which, a liquid (9) exits the nozzle tube passage (58), andii) a nozzle tube wall (71) extending up to a downstream end (72) and having an outer surface (75), andb) an air cap (40) comprising a nozzle aperture (70) delimited by a nozzle aperture edge (64), the nozzle aperture edge (64) being arranged radially outward the downstream end (72).Between the nozzle aperture edge (64) and the outer surface (75), an atomizing gas outlet (54) is formed circumferentially around the nozzle tube outlets (52), such that, in use, a pressurized atomizing gas (110) exits through the atomizing gas outlet (54) and atomizes the liquid (9) exiting the nozzle tube outlets (52).

A computer-implemented method for management of a technical system, comprising the steps of: injecting randomized controlled signals in control decisions; ensuring that the injected randomized controlled signals occur within normal operational ranges and constraints; receiving sensor data from a plurality of sensors associated with the technical system in response to the injected randomized controlled signals; receiving electronic control unit data from a plurality of electronic control units in response to the injected randomized controlled signals; and parsing the sensor data and the electronic control unit data into system responses associated with the injected randomized controlled signals; computing confidence intervals relating to a causal relationship between system signals and a measured utility based on the injected randomized signals, the sensor data and the electronic control unit data; and selecting optimal signals for the control decisions based on the computed confidence intervals.

The present disclosure provides bonded abrasive articles including abrasive particles retained in a binder. The abrasive particles are oriented at a predetermined angle greater than 0 degrees and less than 90 degrees with respect to a longitudinal axis of the bonded abrasive article. Fifty percent or more of the abrasive particles are oriented within 15 degrees above or below the angle, as measured using microscopy image analysis under magnification.

The disclosure relates to a sensored insulation plug (2) for insertion into the rear cavity of a medium or high-voltage separable connector in a national grid power distribution network. It insulates a connection element on elevated voltage and senses the elevated voltage. The insulation plug features a rotationally symmetric body (140) made of electrically insulating material (610). It includes an integrated sensing capacitor (150) functioning as a high-voltage capacitor in a sensing voltage divider, with a high-voltage electrode (160), in use connected to the connection element, and a sensing electrode (170) embedded in the insulating material (610). The dielectric of the sensing capacitor is formed by a portion (180) of the insulating material (610). The insulation plug also has a circuit board (206) with a signal contact (360) connected to the sensing electrode (170).The sensored insulation plug (2) includes a temperature sensor (500) on the circuit board, with a sensor probe (510) that senses the temperature in its vicinity, either in surface contact with or thermally coupled to the insulating material (610), to measure its temperature.

A precursor abrasive structure for use in forming a bonded abrasive article, the precursor abrasive structure including: abrasive particles; a binder medium; and a pore inducing material, wherein the pore inducing material is not flammable and is substantially insoluble in water.
