The invention relates to a method for cleaning a phosgene-conducting apparatus by pressurization with ammonia gas to constant pressure. In this way, phosgene residues in the apparatus to be cleaned are decomposed effectively.

A system and method for cleaning, protecting and lubricating hyperbolic rollers and bearings for bending, using air and oil, placed in a rotating rotor (1) that contains rollers (32) placed on bearings (34) and shafts (33) inside roller housings (30), where rollers (32) are positioned at an angle with respect to the bending axis and, as bending occurs they cause bending and also as rotor (1) rotates around the item being bent it straightens and feeds the item. Rollers (32) are placed on bearings (34) and are protected through rotational seals (35). The bearings' (34) area of rollers (32) inside the rotational seal (35) is supplied with air at pressure higher than the atmospheric, so that inflow of contaminants are inhibited, or is supplied with air enriched with oil so that bearings (34) are lubricated, and rotational seals (35) located next to bearings (34) of the rollers (32) allow the air flow from the area between the bearings towards the surrounding area.

A cleaning fluid includes a static liquid (13) at a first temperature, a dynamic liquid (16) that flows toward an object held in the static liquid (13), and a fine gas bubble group (22) formed from a gas at a second temperature that is different from the first temperature, the gas being entrapped by a flow of the dynamic liquid (16) and flowing toward the object. This can provide a cleaning fluid that exhibits a remarkably better cleaning effect than ever before.

The present invention provides a method for cleaning a component for use in an ultra-high vacuum. The method may comprise the steps of placing the component to be cleaned in a vacuum furnace chamber; plasma cleaning the component at a temperature of greater than about 80 C.; and evacuating the chamber to a pressure of less than about 10E-5 mbar. Apparatus for performing such methods and kits comprising said components are also provided.

A waterblasting system includes a fluid supply device, an air supply device, and a waterblasting tool. The air supply device contains a battery and an alternator in a single unit. The alternator is operated by compressed air from a separate air compressor and generates electric power, at least some of which is used to charge the battery.

The disclosure discloses a convenient cleaning apparatus and cleaning method for an industrial control computer, including an industrial control computer body (1), and a heat dissipation hole is formed in a front side wall of the industrial control computer body (1), and a heat dissipation net (2) is arranged in the heat dissipation hole; a first cleaning device is arranged inside the industrial control computer body (1), and the first cleaning device is configured to clean the heat dissipation net (2); a plurality of heat dissipation fins (3) are arranged on an outer wall of an upper end of the industrial control computer body (1); and a second cleaning device is arranged outside the industrial control computer body (1), and the second cleaning device is configured to clean the heat dissipation fins (3). In the disclosure, by providing the first cleaning device and second cleaning device, cleaning of the heat dissipation net and the heat dissipation fins can be completed, which reduces the dust attached to the surfaces of the heat dissipation net and the heat dissipation fins to achieve high efficient heat dissipation. In addition, there is no need for a worker to clean, which reduces labor intensity of the worker, and also improves safety of cleaning for the industrial control computer body.

The present disclosure generally relates to an electronic device peripheral cleaning cabinet and a method for cleaning such peripherals. In an example, a peripheral cleaning cabinet includes a cabinet body, a door, a cabinet gas line, and a support shelf. The cabinet body includes an exhaust port. The door is mechanically coupled to the cabinet body. The cabinet gas line includes a gas valve and a nozzle. The gas valve is fluidly coupled to the nozzle. The nozzle is disposed in the cabinet body. The cabinet gas line is configured to supply a gas to flow into the cabinet body. The support shelf is disposed in the cabinet body and is configured to support a peripheral. The support shelf is configured to allow the gas to flow from the nozzle, through the support shelf, and to the exhaust port.

The invention solves the problem of the construction of a lance of a cleaning kit for medium-voltage power devices. The lance is equipped with an external assembly (A) and an internal assembly (B) placed therein, wherein the external assembly (A) constitutes a head (1) with clamps (2) and (3) of connections, mounted in it from the front, and connected to a body (4). The body (4) is detachably connected to an extension (5), which at the opposite end is detachably connected to a dispensing nozzle (6).

A robotic device for working on a surface includes a body including: a tool for working on the surface; a controller moving the body along the surface; a first set of at least two rotors mounted to the body and generating thrust in a first direction towards the surface; and a second set of at least two rotors mounted to the body and generating thrust in a second direction away from the surface. A sensor measures a distance between the body and the surface, and a computer adjusts the first set of rotors and the second set of rotors in response to the sensor to place the body in position to work on the surface. In particular, the first set of rotors and the second set of rotors generate a net force on the body to it in non-contact position to work on the surface.

A drying fluid can be uniformly supplied to a substrate. A substrate drying apparatus includes a processing chamber and a cover unit. The processing chamber is provided with an opening through which the substrate is carried in and out. The cover unit is configured to open or close the opening. Further, the cover unit includes a diffusion space and a rectifying member. The diffusion space is configured to diffuse a drying fluid therein. The rectifying member is configured to rectify a flow of the drying fluid diffused in the diffusion space and allow the rectified drying fluid to be flown out into the processing chamber from the diffusion space.
