The fin and condenser coil cleaning device for air conditioner units is a cleaning device for cleaning the fins and condenser coils of window-mounted air conditioner units. A horizontal support is driven to selectively raise and lower with respect to the fins on the exterior portion of an air conditioner unit. The horizontal support carries nozzles for spraying water on the fins at sufficient pressure that the water passes through the fins and cleans the condenser coils contained within the housing of the air conditioner unit. A plurality of brushes are mounted on the horizontal support for brushing the fins as the horizontal support moves vertically with respect thereto. Sensors may be provided for controlling the direction of vertical movement of the horizontal support and for selectively actuating a motor and a pump for driving movement of the horizontal support and spraying the water through the nozzles.

A collapsible containment berm having a floor and a peripheral sidewall, a plurality of brace assemblies integrally carried on an external surface of the sidewall and on an adjacent underside surface of the floor, each brace assembly comprising a rigid sidewall support member connected to the external surface of the sidewall and oriented upright when deployed, a rigid buttress member having a first end and an opposite second end, and hingedly connected to an upper end of the sidewall support member that allows the buttress member to arc toward or away from the sidewall, a rigid floor member hingedly connected at the third end to the other end of the buttress member, and a sleeve connected to the underside of the floor and adapted to receive the floor member. The floor member slides in and out of the sleeve and moves the buttress member in and out of a bracing position with respect to the sidewall.

A substrate processing apparatus includes a substrate holding unit having a spin base; a blocking member having a substrate facing surface facing an upper surface of the substrate held by the substrate holding unit and having a diameter larger than the spin base; a blocking member lifting unit raising and lowering the blocking member between a blocking position where a space between the substrate facing surface and the upper surface is blocked from lateral side on the upper surface and a retreat position where the space is not blocked from the lateral side on the upper surface; guards including an inner side and an outer side guards respectively surrounding periphery of the substrate holding unit and surrounding periphery of the inner side guard. An inner circumferential end of the outer side guard is positioned on radial outer side of an inner circumferential end of the inner side guard.

A grease and food particle trap for use with an oven shooter tube cleaning system that provides improved resistance to clogging and improved maintenance better matching the ability of the shooter tube cleaning system to provide complete cleaning and removal of grease and food particles is provided. An auxiliary heating system may provide improved energy efficiency and temperature control for cleaning operation by separately heating the cleaning solution upstream from the shooter tube prior to delivering a cleaning spray to the cooking volume.

Systems and methods for improved removal and disposal of concrete waste by using a washout container on a roll-off truck, whereby the washout container may include a cradle and liner that are both durable and easy to maintain.

Retrofit box systems to maximize operational capacity of inaccessible floors are described. The retrofit box system includes a gate complex that provides fluid communication between an inaccessible floor and a box, and a box to deliver a cleaner to the inaccessible floor and adapted for equalizing pressure when the inaccessible floor is under water while minimizing waste seepage from the retrofit box system. The retrofit box system further includes a power system and a control system to deliver the cleaner to the inaccessible floor and remove waste from the inaccessible floor and the box.

A system for and method of removing residues, deposits, and debris from a substrate that has been marked by a chemical etching process is disclosed. The system includes one or more upper sprayers that deposit a cleaning solution to a top surface of the product as it passes beneath the one or more upper sprayers. The system further includes at least one upper brush that operates to scrub the top surface of the product after the cleaning solution has been applied thereto. The system optionally includes one or more lower sprayers and lower brushes to clean a bottom surface of the product as it is conveyed through the system. The system further includes an air knife system that assists with drying the product prior to exiting the system. The system further includes a controller that is operable to adjust various system parameters.

The disclosure belongs to the technical field of die cleaning, and particularly relates to an automatic die cleaning device with reusable cleaning fluid. The automatic die cleaning device with reusable cleaning fluid comprises a robot, a cleaning fluid cyclic-spraying system and a die overturning mechanism. The automatic die cleaning device can spray the cleaning fluid to a die to clean oil stains off the surface of the wheel die, thus realizing the function of automatically cleaning the oil stains off the surface of the die; and the automatic die cleaning device also has the function of reusing the cleaning fluid, thereby saving the cleaning fluid and reducing the influence on the environment. The cleaned die surface is smooth, and the effect is ideal. The automatic die cleaning device reduces the labor intensity, meets the requirement of high-efficiency production, and improves the production efficiency.

The substrate processing apparatus includes common piping which guides a processing liquid to a branching portion, supply piping which guides the processing liquid from the branching portion to a chemical liquid nozzle, return piping which guides the processing liquid from the branching portion, and a discharge valve which changes a flow rate of the processing liquid supplied from the common piping to the branching portion. The discharge valve makes a valve element stationary at a plurality of positions including a discharge execution position at which the processing liquid is supplied from the common piping to the branching portion at a flow rate larger than a maximum value of a suction flow rate and a discharge stop position at which the processing liquid is supplied from the common piping to the branching portion at a flow rate smaller than the maximum value of the suction flow rate.

In an aspect, there is disclosed an example of apparatus (10) for cleaning a wheelbarrow (12) with a fluid. The apparatus (10) includes a receptacle (16), a filter (18) fittable to the receptacle (16) in a fitted condition and a support arrangement (19) adapted to hold the wheelbarrow (12) in a tipped orientation relative to the receptacle (16) such that matter within a tray of the wheelbarrow is moveable at least partially via gravity into the receptible (16). Various examples of the apparatus, a system, a kit and associated methods of use are also disclosed.
