A system and method for cleaning the fire detection sensor of a fire detection device, such as a smoke detector, includes flowing halocarbon liquid over the fire detection sensor. A pump continuously recirculates the halocarbon liquid between a sensor holder and a reservoir, while a cleaning action is applied by an agitator to the fire detection sensor while it is under a stream of the liquid or in a bath of the liquid. The halocarbon liquid is typically an industrial electronics cleaner such as Novec™, which removes dirt, dust, grease and oil from the fire detection sensor without harming electronic components.

A diatomaceous earth filter cleaner for cleaning flex tubes attached to a tube sheet of a diatomaceous earth filter. The diatomaceous earth filter cleaner has a hollow tube, a blast jet housing, an inner diameter scrub brush, and a fitting at an end of the hollow tube for coupling a hose connected to a water supply. The hollow tube of the diatomaceous earth filter cleaner has a length with a first end and a second end for receiving a flex tube. The blast jet housing is attached to the first end of the hollow tube and comprises an angled lip and a restricted orifice formed by an inner circumference of the blast jet housing for receiving a flex tube. The inner diameter scrub brush is received within the inner circumference of the blast jet housing and has an orifice for cleaning an outer circumference of the flex tube.

Embodiments of the present disclosure generally relate to methods for detecting end-points of cleaning processes for aerospace components containing corrosion. The method includes exposing the aerospace component to a first solvent, exposing the aerospace component to a first water rinse, and analyzing a first aliquot of the first water rinse by absorbance spectroscopy to determine an intermediate solute concentration in the first aliquot, where the intermediate solute concentration is greater than a reference solute concentration. The method further includes exposing the aerospace component to an aqueous cleaning solution to remove corrosion from the aluminum oxide layer, exposing the aerospace component to a second solvent, and exposing the aerospace component to a second water rinse, and analyzing a second aliquot of the second water rinse by absorbance spectroscopy to determine a post-clean solute concentration in the second aliquot, where the post-clean solute concentration is less than the intermediate solute concentration.

An electrode, a preparation method therefor, and uses thereof. Titanium or titanium alloy is used as a base material of the electrode, the outer surface of the base material is coated with a composite material coating, and the composite material coating is prepared by coating a composite material solution and carrying out drying and sintering. The composite material solution is a nanoscale solution formed by dissolving transition metal elements in ethanol. The nanoscale solution is an ethanol solution of the nanoscale transition metal with particles of the transition metal as solutes thereof. The transition metal elements are platinum, iridium, ruthenium, gold, cerium, rhodium, tantalum, manganese, nickel, palladium, yttrium, gadolinium, cobalt, europium, lanthanum, neodymium, zirconium and titanium, and the molar ratio of the transition metal elements platinum, iridium, ruthenium, gold, cerium, rhodium, tantalum, manganese, nickel, palladium, yttrium, gadolinium, cobalt, europium, lanthanum, neodymium, zirconium and titanium in the composite material solution is 5-15:23-34:14-21:1-7:9-17:3-12:15-27:3-6:2-9:10-23:15-27:2-8:15-30:3-12:4-14:1-10:6-15:20-50.

A substrate cleaning apparatus includes a porous suction part having a polygonal pillar shape with a plurality of cleaning surfaces, a transfer unit to transfer a substrate with a plurality of semiconductor devices toward the porous suction part, and to contact the semiconductor devices with one of the plurality of cleaning surfaces, and a rotation driving part to rotate the porous suction part.

The present disclosure provides a cleaning machine, including: a cleaning chamber; a turn table having a plurality of areas arranged around a rotary axis, configured to turn one area of the plurality of areas to the cleaning station and another area to the transport station, each of the plurality of areas having: a cleaning tank including a closable opening, a rotating device arranged at the cleaning tank, and a cleaning table on which the object is placed, and which is arranged on the rotating device and rotatably arranged in the cleaning tank; a nozzle moving device arranged in the cleaning station; a cleaning nozzle arranged on the nozzle moving device; a shutter arranged in the cleaning station and closing the closable opening; and a shutter moving device configured to move the shutter toward the closable opening.

A mop washing bucket has a container with an interior volume defined by a bottom and a wall extending upwardly from the bottom, a fluid inlet affixed adjacent to the bottom of the container, and a fluid outlet formed on the container in a location above the fluid inlet. The fluid inlet is adapted to be connected to a water hose. The fluid inlet extends through the wall of the container so as to have one end in the interior volume of the container and another end exterior of the wall of the container. The fluid outlet is adapted to allow water from the interior volume of the container to flow outwardly of the container.

A system and method for deglazing or defrosting items, for cleaning wares, and/or for thermalizing/rethermalizing food items. The system includes a tank for holding fluid and a wash pump for creating a rolling washing action within the wash tank. The method includes placing items into the fluid so that as the fluid rolls within the wash tank, the items become deglazed or defrosted. The system further includes a discharge manifold with a plurality of discharge jets, a flow balancer for equalizing flow to multiple sections of the tank, and a diffuser plate for equalizing flow within a section of the tank. The various components of the system can be removed for cleaning, inspection, and/or replacement. The discharge manifold is accessible for removal and is configured to be easily cleaned.

A sensor assembly includes a sensor including a sensor lens, a casing mounted to the sensor, and a fluid nozzle mounted to the casing. The casing at least partially defines a duct positioned to outlet airflow across the sensor lens, and the duct defines a direction of airflow. The fluid nozzle is aimed through the duct in the direction of airflow.

An improved game washer is compatible with a variety of receptacles and includes one or more cradles for receiving and holding various types of game. Agitation for washing game is provided via one or more water flows at one or more outlets of an agitator. An outlet engages a bottom of a cradle to provide water flow at the cradle. The agitator extends out of an opening of a receptacle at a central portion thereof to receive a water supply, while forming a gap at the opening to permit a flow of water and waste material out of the receptacle.
