A wafer processing apparatus includes a rotating chuck which is rotatably installed inside a cup housing and on which a substrate is mounted, a nozzle table rotatably installed inside the rotating chuck, a guide installed inside the nozzle table, a moving module movably installed on the guide, a guide arm configured to support a fluid supply line part, a lower nozzle part coupled to the guide arm to move together with the moving module and connected to the fluid supply line part, a driving shaft part connected to the rotating chuck and the nozzle table to rotate the rotating chuck and the nozzle table, a moving shaft rotatably installed inside the driving shaft part and connected to the moving module to move the moving module, and a driver connected to the driving shaft part and the moving shaft.

A mattress cleaning system receives a mattress in a tank of wash liquid so that the mattress is fully submerged. A pressure applicator, for example a mechanical structure or a jetted flow of wash fluid, applies a cyclical compressive force to the sleeping surface of the mattress while the mattress is fully submerged so as to cause flushing of the wash liquid outwardly of the mattress through at least the sleeping surface of the mattress. When using a barrier to isolate one of the surfaces of the mattress on a first side of the barrier from remaining surfaces of the mattress on a second side of the barrier, use of a blower to create an air pressure differential between opposing sides of the barrier causes migration of the wash liquid through the mattress from the isolated surface of the mattress to the remaining surfaces for drying the mattress.

A sash system includes a sash, a counter-weight coupled to the sash by a coupling member, a locking mechanism coupled to at least one of the sash and the coupling member, and a controller coupled to the locking mechanism. The locking mechanism is transitionable between an open configuration where the locking mechanism does not inhibit movement of at least one of the sash and the coupling member, and a locked configuration where the locking mechanism inhibits movement of the at least one of the sash and the coupling member. The controller is configured to control operation of the locking mechanism to selectively transition between the open configuration and the locked configuration based on a condition of the sash. The sash and the counter-weight are configured such that when the locking mechanism is in the open configuration, the sash lowers due to gravity.

The present disclosure relates generally to protective devices and cover members. In some embodiments, cover members are provided that are operable to protect covered components and to allow heat dissipation from the components. Cover members of the present disclosure are suitable for use with heat exchangers including, for example, those provided with hot water pressure washers.

An apparatus includes a top cover having a first side and a second side, the second side opposite the first side, the top cover tapered and comprising an opening at a top of the tapered portion to accept a paint brush handle within and two flexible tabs on a lower portion of the first side, and a bottom cover having a first side and a second side, the second side opposite the first side, the first side of the bottom cover comprising two slots positioned on a top portion, the bottom cover configured to accept a paint brush bristle portion within, a lower part of the tapered portion of the top cover configured to releasably lock to the bottom cover when the two flexible tabs are engaged within the two slots.

A docking station for a hand-held filament extension atomizer device includes a receiver to receive the device, station electronics, a recharging point for the device arranged to connect with a power source of the device, a power connection to an alternating current power source, and a cleaning reservoir of cleaning solution. A method of operating hand-held dispenser to dispense fluid as a mist includes receiving a signal at a motor contained in a casing in response to a user triggering an actuator on the casing, activating the motor to provide fluid to a filament extension atomizer contained in the case from a reservoir contained in the casing, the motor to cause the filament extension atomizer to generate a mist, and using an air source contained in the casing arranged adjacent the filament extension atomizer to provide air flow to direct the mist to a nozzle that is arranged to allow the mist to exit the casing.

A wafer processing apparatus includes a rotating chuck which is rotatably installed inside a cup housing and on which a substrate is mounted, a nozzle table rotatably installed inside the rotating chuck, a guide installed inside the nozzle table, a moving module movably installed on the guide, a guide arm configured to support a fluid supply line part, a lower nozzle part coupled to the guide arm to move together with the moving module and connected to the fluid supply line part, a driving shaft part connected to the rotating chuck and the nozzle table to rotate the rotating chuck and the nozzle table, a moving shaft rotatably installed inside the driving shaft part and connected to the moving module to move the moving module, and a driver connected to the driving shaft part and the moving shaft.
