A cleaning apparatus includes a connection part rotatably mounted to a rotatable member. The connection part is in the form of a disc 36 of plastics material, with a central cavity with four radial passages extending therefrom leading to nozzles for steam to pass therethrough for cleaning purposes. In use the disc is rotated at a required speed to, for instance, clean a conveyor.

Cleaning articles including a heat engine incorporated therein. The cleaning article may include a substrate (e.g., a non-woven wipe) including one or more layers. The heat engine may be in the wipe or pad, and includes a reactive metal composition which upon contact with a salt water (e.g., saline) composition, reacts to produce heat. The cleaning article may thus produce water vapor and/or steam upon activation of the heat engine. A venting structure may be provided adjacent to or surrounding the heat engine that includes an impermeable material (e.g., impermeable to water and/or air or other gas), which includes one or more vents through the impermeable material. The venting structure directs water vapor and/or steam to a desired face of the cleaning article, away from the user. A heat barrier layer may insulate a user's hand from the generated heat, and/or a handle may be attachable to the pad.

A vapor-based system and method for treating one or more components of a gas turbine engine. The system includes a treatment compound contained in a storage vessel. The storage vessel being operably coupled to a delivery module. The delivery module delivering the treatment compound at one or more locations of the gas turbine engine such that the treatment compound is a vapor when exposed to an engine air-path.

Cleaning articles including a heat engine incorporated therein. The cleaning article may include a substrate (e.g., a non-woven wipe) including one or more layers. The heat engine may be in the wipe or pad, and includes a reactive metal oxide which upon contact with water, reacts to produce heat. The cleaning article may thus produce water vapor and/or steam upon activation of the heat engine. A venting structure may be provided adjacent to or surrounding the heat engine that includes an impermeable material (e.g., impermeable to water and/or air or other gas), which includes one or more vents through the impermeable material. The venting structure directs water vapor and/or steam to a desired face of the cleaning article, away from the user. A heat barrier layer may insulate a user's hand from the generated heat, and/or a handle may be attachable to the pad.

A method for cleaning components of a gas turbine engine is presented. The method includes introducing a working fluid into a gas flow path or a cooling circuit defined by the one or more components of the gas turbine engine such that the working fluid impinges upon a surface of the one or more components of the gas turbine engine, wherein the working fluid includes a plurality of detergent droplets entrained in a flow of steam. A system for cleaning components of a gas turbine engine are also presented.

The present invention concerns a method for cleaning a reactor (4) for treating a lignocellulosic biomass (P), said method comprising the following steps: a) draining the reactor of the reaction mixture containing the biomass, b) filling the reactor with a basic aqueous solution (EB), c) draining the reactor, d) injecting steam (V) into the reactor, e) filling the reactor with an aqueous solution (E), f) draining the reactor.

A process for cleaning an object, such as for instance an outdoor playground structure or other communal object, includes applying a degreaser solution to a surface of the object. The surface is also power washed using water at or above ambient temperature, and additionally steam is applied to the surface. A disinfectant solution is applied to the surface, and if a final contaminant level of the surface is below a predetermined threshold value then finally an antimicrobial product is applied. The process removes contaminants including microorganisms and organic residues and provides a surface that remains resistant to recontamination for an extended period of time.

A method of cleaning plugged or dirty porous metallic filter elements to regain filter activity, comprising the steps of: steaming a filter element for a first period of time; submerging the filter element in a first solution; and exposing the first solution to ultrasound waves for a second period of time.

To simplify management of a process of sterilization of a filling nozzle.

In a method for sterilizing a filling nozzle, hot water or a liquid chemical agent is fed to drink supply piping (7) that feeds a drink to a plurality of filling nozzles (2a) at the same time, the hot water or liquid chemical agent is discharged from all the filling nozzles (2a), a flow rate of the hot water or liquid chemical agent is detected at all the filling nozzles (2a), a representative temperature of the hot water or liquid chemical agent upstream or downstream of at least one filling nozzle is measured, and a sterilization process is ended when both the flow rate at each filling nozzle and the representative temperature reach respective target values.

A dynamic, reconfigurable, and modular cleaning device utilizes software, sensors, and modular components to provide a one-size-fits-all approach to cleaning conveyor belts. The cleaning device secures to a body or frame associated with a conveyor belt, in which an associated cleaning head cleans the conveyor belt's surface. The cleaning head has an arm that extends from its body and inserts into a corresponding opening on a connecting frame associated with the cleaning device. The cleaning head is then secured in place via a cylindrical pin that extends through aligned holes on the arm and the connecting plate. Insertion of the pin connects the components together, and removal of the pin enables a user to disconnect the cleaning head and swap a new one in its place, such as to provide a different cleaning action.
