Systems and methods for applying a liquid coating to a substrate are disclosed herein. One exemplary method includes calibrating flow rate of a material through a coating system. A target flow rate for the material through a spray nozzle is received, a first operating pressure of the coating system based upon the target flow rate is calculated, and the material is ejected onto a least part of a surface with the material flowing through the spray nozzle at the first operating pressure of the coating system. Subsequent to a comparison between an operating flow rate and the target flow rate, the operating pressure is adjusted to a second operating pressure and at least part of the substrate is sprayed with the material flowing through the spray nozzle at the second operating pressure of the coating system.

An ozone disinfecting system includes a water holding tank configured to hold water for use by the ozone disinfecting system. An ozone generator machine is configured to convert the water into an ozone cleaner agent. An ozone holding tank is configured to hold the ozone cleaner agent created by the ozone generator machine. A drain is configured to drain fluid from the ozone holding tank to the water holding tank. A pump is configured to cycle the fluid from the water holding tank to the ozone generator machine and into the ozone holding tank. A controller is configured to control the pump, the ozone generator machine, and the drain. Wherein, the controller controls the pump, the ozone generator machine and the drain to create the ozone cleaner agent from the water and cycle it between the water holding tank and the ozone holding tank at a specified cycle time.

An adjustable temperature treatment assembly includes a top seat and a bottom seat respectively connected to the wall in a shower stall. Two guided rods are connected between the top seat and the bottom seat. An up-and-down unit includes a threaded rod connected between the top seat and the bottom seat, a movable seat connected to the threaded rod, a rotary member, a holding member and a first driving member. The holding member is connected to the rotary member. A warm-hot water unit includes a heating box, and a shower head which is connected to a holding member. A control unit is electrically connected to the first driving member to spin the threaded rod to move the movable seat up and down. A driving member is controlled by the control unit to swing the rotary member together with the shower head left and right.

A high-pressure cleaning device has a conveying pump and a conveying conduit with a spray opening. The conveying conduit conveys cleaning liquid, conveyed by the conveying pump, in a conveying direction from the conveying pump to the spray opening of the conveying conduit. A switch element is provided that has at least a first switched state and a second switched state. An actuator is provided that adjusts the switch element between the first switched state and the second switched state. The high-pressure cleaning device is provided such that the actuator adjusts the switch element between the first switched state and the second switched state by an adjusting force effected by the cleaning liquid on the actuator.

A work machine in which an engine and a reserving unit configured to reserve lubricating oil to be supplied to the engine are connected by a lubricating oil channel, and the lubricating oil is circulated, wherein at least a part of the lubricating oil channel and at least a part of a working fluid channel for a working fluid to be supplied to a work unit of the work machine are arranged such that heat can be exchanged between the lubricating oil and the working fluid.

A portable fluid tank apparatus for removably mounting on supports for a bulk seed container of a seed cart may include a pedestal configured for resting on the container supports of a seed cart in a seed box support position, a tank housing located on a portion of the pedestal and defining a tank chamber configured to hold a liquid, and an accessory housing located on another portion of the pedestal and defining an accessory compartment configured to hold at least one accessory. The accessory housing may include a base portion mounted on the pedestal and defining an opening for accessing the accessory compartment, and a lid portion mounted on the base portion and being movable with respect to the base portion between a closed position restricting access to the accessory compartment through the opening and an open position permitting access to the accessory compartment through the opening.

Exemplary embodiments wet-on-demand dispensers are disclosed herein. An exemplary dispenser for dispensing wet-on-demand substrates includes a housing, a container for holding a fluid, one or more wetting tips in fluid communication with the container. Each of the one or more wetting tips has a movable valve member. The exemplary dispenser further includes a holder for holding a roll of substrate and the movable valve members are moved as a function of contact with the substrate.

A solenoid valve in a manifold is commanded to move to a closed position. Upon activating a pump to supply fluid to the manifold via a supply line, a first pressure is determined in the supply line after commanding the solenoid valve to move to the closed position. Upon deactivating the pump to stop supplying fluid to the manifold, a second pressure is determined in the supply line. Based on a difference between the first pressure and the second pressure, the solenoid valve is determined to be one of (a) at least partially open or (b) in the closed position.

An aerial operations system for performing various tasks such as painting is provided. The modular aerial operations system includes an aerial vehicle capable of vertically taking off and landing, hovering and precisely maneuvering near walls and other structures. The aerial vehicle may be a rotorcraft such as a multicopter. In an aspect, as aerial vehicle paints one or more designated surfaces using detachable arms and equipment. The system may paint the designated surface in one of several available techniques using paint provided in a container such as an attached reservoir, a base station, a paint can, or the like. The aerial operations system provided may also be configured to perform a variety of other tasks.

A dispenser of liquid products for sanitization, such as bactericides, germicides, disinfectants, alcohol gel, moisturizers, among others, featuring innovative construction characteristics which distribute the product onto the user's hands or onto surfaces of various objects, via spraying in micro droplets, enabling a uniform distribution, suitable to be installed in public environments such as restrooms, restaurants, malls, offices and commercial facilities.
