An ultraviolet razor blade treatment system for providing a cleaning treatment to a shaving razor is disclosed. The ultraviolet razor blade treatment system can include a shaving razor cleaning unit that has at least one ultraviolet radiation source and sensor to clean surfaces of the shaving razor for purposes of disinfection, sterilization, and/or sanitization.

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.

A method and system for removing hydrocarbon deposits from a heat exchanger tube bundle using an organic solvent. After contact with a heat exchanger tube bundle, the contaminated organic solvent may be treated to remove solids, base waters, and/or suspended hydrocarbons, and then again contacted with a heat exchanger tube bundle for the removal of hydrocarbon deposits. This allows for the removal of hydrocarbon deposits from a heat exchanger tube bundle in an efficient and environmentally friendly manner. The treatment of the heat exchanger tube bundle is also preferably performed using a method and system by which, through contact of the heat exchanger tube bundle with an organic solvent, a large percentage of hydrocarbon deposits are removed from the heat exchanger tube bundle in a short period of time.

A collection apparatus for collecting waste from cleaning operations performed on an aircraft turbine engine includes a frame structure, a support arm having a first end movably attached to the frame structure and an opposite second end, an actuator device adapted to enable raising and lowering the support arm, a waste storage tank, a duct having an inlet end and an opposite outlet end adapted to be removably connected to the waste storage tank, and a flexible duct portion having a flexible portion inlet end and a flexible portion outlet end. The inlet end of the duct is adjustably supported by the second end of the support arm. The flexible portion outlet end engages the inlet end of the duct in fluid communication, and is bendable both up/down and sideways and is expandable in length between the flexible portion inlet end and the flexible portion outlet end.

A washing container for washing or maintaining various objects includes opposite side portions, end portions, and a bottom portion. Embodiments include at least one lower support having an engagement gap extending between lower support arms and configured to releasably secure the objects. Some embodiments include opposing lower supports that secure opposite ends of the objects. An upper support arm may be used independently or together with one or more lower supports to secure one or more objects, in various positions, within the washing container. A perforated support platform support the objects above the bottom portion of the washing container and allows fluids and debris to pass to the bottom portion and into a drain trough. A debris basket within the trough limits the passage of debris into a drain.

A blend of aliphatic hydrocarbons and polyglycol ether(s) is used in a process for cleaning railroad tank cars that have been gravity drained of hydrocarbon fluids but may be left with a residuum containing heavy hydrocarbons, paraffin and noxious gas. A simple recirculation system is established between the chemical source, the contaminated railcar, canister filters and back to the chemical source. Contaminates are removed from the cleaning chemical by the filters and there is no water or steam used which might otherwise damage the railcar.
