A device for releasing volatile substances comprising a container containing the volatile substances located in a fixed position, and means for generating an air flow in order to release the volatile substances, the means for generating an air flow comprising a movable body, the movement of which generates the air flow; at least one magnet arranged on said movable body; and means for generating magnetic flux, the actuation of which causes the displacement of the movable body by means of the repulsion force between said at least one magnet in the movable body and the magnetic flux. The device enables energy consumption to be improved by using magnetically assisted periodic low-consumption actuation.

An embodiment of the present invention provides an air injection valve-integrated spray for spraying and applying polyurethane foam to a desired portion of a tire. The spray includes a polyurethane foam chamber disposed at an end of a coupling portion and keeping polyurethane foam under pressure and an air delivery chamber delivering air injected from an air injection valve to a breaking portion of the polyurethane foam chamber, in which the breaking portion of the polyurethane foam chamber is broken by air coming out of the air delivery chamber, so the polyurethane foam is sprayed.

A leakage prevention system for a downward spraying-type nebulizer for stacking a biomaterial of a bio-3D printer according to the present disclosure is provided, wherein the system constituting an output unit of the bio-3D printer includes: a nebulizer that downwardly sprays a biomaterial into a form of mist toward a substrate; a vacuum cap that is detachably installed on a upper portion of the nebulizer; a distributor that is connected to the vacuum cap with a hose; a vacuum generating module that is connected to the distributor with a hose; a compressor that generates an air pressure in the vacuum generating module; and a controller that is electrically connected to the vacuum generating module and the nebulizer, controlling an output pressure of the vacuum generating module and an action of the nebulizer.

First and second fluid components are individually pumped to a device from first and second pumps. A first volumetric flow rate of the first fluid component discharged from the first fluid component is measured. A second volumetric flow rate of the second fluid component discharged from the second pump is measured. Operation of at least one of the first and second pumps is controlled based on the measured first volumetric flow rate and the measured second volumetric flow rate to produce a target ratio of the first fluid component and the second fluid component at the device.

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 foam discharge container, including a container main body for accommodating a liquid composition and a foam discharge device which mixes the liquid composition with air and discharges it in a foam form. The foam discharge device has a plurality of porous bodies through which the liquid composition passes when the liquid composition is discharged, the plurality of porous bodies include a tip side porous body arranged in a vicinity of a discharge port of the foam discharge device, and the tip side porous body is composed of polyethylene terephthalate.

A water dispersing system (WDS) that allows a selectable quantity of water to be dispersed into an environment. The WDS utilizes a fan and a water supply assembly. The fan has a frame inside of which are two rotating blades, and preferably a stand. The water supply assembly includes a reservoir, a water tube, and a water dispersing head. Water is gravity fed from the reservoir, through the water tube and out of the head. Water from the head is directed into the first fan's rotating blades. Once the water hits the blades, the water is re-directed back out through a front grill on the fan. The second fan blades project air outward. The amount of water that comes from the WDS can be selectably chosen, from a light mist to a heavier spray, and the temperature of the water can be lowered by placing ice into the reservoir with the water. An excess water basin catches any water that drips downward from the blades.

A treatment system for spraying treatment fluid onto plants in a field is described. The treatment system includes a highly configurable treatment mechanism including an array of nozzles and valve assemblies coupled into manifolds, and manifold assemblies. The manifolds of the manifold assemblies can be oriented in an open state or a nested state, the open state with no overlap between nozzles of adjacent manifolds and the nested state with overlap between nozzles of adjacent manifolds. The manifolds can have multiple configurations, examples of which include a tube manifold and an offset manifold. The nozzles of the system can have multiple configurations, examples of which include a tri-spray nozzle, a bar nozzle, a fan nozzle, and a deflected fan nozzle. The system can be controlled by a system controller which detects plant material and instructs a nozzle or combination of nozzles to spray treatment fluid.

A vehicle wash component for a vehicle wash system, including a frame portion and an air delivery portion disposed on the air delivery portion. The air delivery portion is configured to emit high velocity air onto a vehicle exterior. A fluid delivery portion is disposed on the frame portion. The fluid delivery portion is configured to emit high pressure fluid onto the vehicle exterior. The fluid delivery portion is disposed rearward from the air delivery portion with respect to a direction of travel of a vehicle. The air delivery portion and the fluid delivery portion are configured to emit the high velocity air and the high pressure fluid onto the vehicle exterior simultaneously.
