The present invention relates to an apparatus (20) for clearing a plugged control line (12), in particular for clearing a plugged surface controlled sub-surface safety valve (11) control line (12), the apparatus (20) comprising a connecting means (27) configured to connect the apparatus (20) to an upstream end of the plugged control line (12); and a pumping means (21, 22) configured to pump a dissolvent (30) through the connecting means (27) into the control line (12) to build up dissolvent pressure in the control line (12). The invention further comprises a bore system and a method for clearing a plugged control line (12).

Valve and related assemblies, systems, and methods may include a self-cleaning feature that may be configured to at least partially displace material from a portion of the valve. Such valves may be utilized in a pressure exchanger.

An apparatus and process to clean medical devices, such as endoscopes, that includes an automatic endoscope reprocessor system equipped with a peracetic acid/hydrogen peroxide sensor are described.

A cleaning system comprise: a first pipe 20 connected to a reactor 10 used for producing polysilicon by using chlorosilane as a raw material; a heat exchanger 30 connected to the first pipe 20; a second pipe 60 provided between the heat exchanger 30 and the first pipe 20; and a driving unit 50 provided at the first pipe 20 or the second pipe 60. A cleaning liquid circulates through the first pipe 20, the heat exchanger 30 and the second pipe 60 by the driving unit 50.

A hand-held drain cleaning apparatus which includes a control housing comprising an upper body portion and a lower body portion, a release valve member being movable between at least a first position wherein the release valve member prevents fluid from flowing into a first fluid passageway from a second fluid passageway, and a second position wherein fluid can flow from the second fluid passageway and into the first fluid passageway. The hand-held drain cleaning apparatus further includes a flexible, tubular member having first and second end portions, and a terminal discharge member in fluid communication with the second end portion of the tubular member.

A method for cleaning a paint spray gun, which comprises a rotating atomization head to apply a coating material while rotating and an outer circumferential tube to cover the exterior of the rotating atomization head, has a cleaning solution application step for applying a cleaning solution to the external face of the outer circumferential tube, and a rotating atomization head rotation step for generating a rotational flow between the rotating atomization head and the outer circumferential tube by rotating the rotating atomization head. The cleaning solution flowing down the external face of the outer circumferential tube applied in the cleaning solution application step penetrates between the rotating atomization head and the outer circumferential tube by way of the rotational flow. Such method uses a small amount of cleaning solution for cleaning external and internal faces of the outer circumferential tube and the external face of a rotating atomization head.

A high temperature food treatment method is disclosed wherein by alternatingly operating between a first final heater (13) and second final heater (23) arranged in parallel on a food processing line (30, 40, 50), it is possible to operate a continuous process, yet significantly reducing the overall downtime of the processing line (30, 40, 50), by performing a cleaning in place process on the final heater (13, 23), not currently being used in the high temperature food treatment process, thereby eliminating or significantly reducing the influence on the processing line (30, 40, 50) downtime by the process elements and/or processing equipment most easily contaminated.

A method for identifying a connection between a first channel and at least one second channel located in a rinsing device. The method including: applying a first testing pressure to the first channel; reading in a first pressure signal representing a first pressure in the at least one second channel; and detecting the connection between the first channel and the at least second channel when the first pressure is one or more of at a predetermined first ratio to the testing pressure and above a predetermined first threshold.

A gas turbine engine system includes a compressor, gas turbine, and combustor including a plurality of late lean fuel injectors supplied with secondary fuel to its interior. The gas turbine engine system includes a wash system in communication with the late lean fuel injectors. The wash system includes a water source; water pump; anti-corrosion agent fluid source with an anti-corrosion agent including a polyamine corrosion inhibitor; anti-corrosion agent supply piping in fluid communication with the anti-corrosion agent fluid source; mixing chamber receiving water and anti-corrosion agent to produce an anti-corrosion mixture in fluid communication with the mixing chamber and the plurality of late lean fuel injectors. Fluid from the mixing chamber including the water, the anti-corrosion agent fluid source, or a mixture thereof is injected, while the gas turbine engine is off-line, into the combustor at at least one of the plurality of late lean fuel injectors.
