A method and device for coating projecting surfaces of discrete projections of a product substrate that has functional units arranged at least partially in recesses. The method includes the steps of: bringing the projecting surfaces into contact with a coating material that is applied on a carrier substrate, and separating the carrier substrate from the projecting surfaces in such a way that the coating material remains partially on the product substrate. In addition, this invention relates to a corresponding device.

An electrostatic spray chilling system is configured to rapidly cool foodstuffs. A conveyor traverses foodstuffs through a chilling tunnel. A chilled primary airflow is provided to the chilling tunnel to cool the foodstuffs. As the foodstuff is traversed through the chilling tunnel, spray modules generate and apply sprays of electrostatically charged fluid onto the foodstuff. The charged fluid droplets are attracted to the grounded foodstuff. The charged fluid droplets can be guided onto the foodstuff by secondary fans, configured to generate subflows of the chilled primary air, and by air guiding baffles.

A painting device is provided with: a bell-shaped cup for discharging paint; a housing for holding the cup so as to be freely rotatable; and first tip openings disposed on the outside in the radial direction on the base end side of the tip side outer peripheral edge of the cup and throwing paint onto a workpiece by spraying shaping air in the direction of the tip. When a tangent line that is tangent to the tip side outer peripheral edge of the cup from a first tip opening is drawn in a front view of the painting device, the first tip opening sprays shaping air at an inclination more to the inside in the radial direction of the cup than the tangent line.

A non-drip hygiene dispenser for dispensing a wipe paper-towel while keeping a clean and sterile working area comprises (a) a wipe paper-towel, (b) at least one reservoir containing liquid, (c) a first stream of compressed air, (d) a second stream of compressed air, an anti-dripping nozzle, (e) rolling means, and (f) cutting means. The anti-dripping nozzle further comprises activating means and a dispensing tip. The activating means comprises a retractable anti-drip needle backed by a spring. The spring retracts backwards when compressed air of the first stream of compressed air presses the spring, thus retracts the anti-drip needle, and thus, unblocks the dispensing tip to allow liquid from the at least one reservoir to flow through the dispensing tip. When the compressed air pressing the spring is released, the retractable anti-drip needle returns to its original place, blocking the dispensing tip to block the passage of liquid remained in the dispenser immediately upon shut off of the dispenser, thus, to avoid undesired dripping. The second stream of compressed air entering the anti-dripping nozzle mixes with the sprayed liquid in order to form a foggy environment around the wipe paper-towel.

The present invention relates to a system, and the method of application thereof, for washing and decontamination comprising nebulizing means (8) of a mixture of at least one first gas and at least one first liquid, and pressurizing means (1) of said first gas, wherein said pressurizing means (1) are in fluid communication with a first pressure-regulating valve (3) and with a second pressure-regulating valve (4),

the first pressure-regulating valve (3) being in fluid communication with a first pressurized tank (5) through first inlet means (31) of said first gas, the first pressurized tank (5) being configured to contain the first liquid, and comprising first outlet means (30) of said first liquid to the nebulizing means (8) through a first valve (6), at a first pressure that is greater than atmospheric pressure,

and wherein the second pressure-regulating valve (4) is in fluid communication with said nebulizing means (8), and is configured to pressurize the gas at a second pressure that is greater than atmospheric pressure.

A nebulizer comprises a housing, a closed pressure system, at least one pressure relief mechanism and a nebulization mechanism. The housing comprises a nozzle, and the nozzle comprises an outlet portion and an inlet portion communicated with a pressurized gas source. The closed pressure system comprises at least one gas inlet and a gas outlet. The at least one pressure relief mechanism is disposed on the at least one gas inlet. The nebulization mechanism is capable of moving to a nebulization position. An interior pressure in the closed pressure system is changed by the at least one pressure relief mechanism to control the nebulization mechanism for nebulization.

Various examples are provided related to low pressure delivery, e.g., less than 250 psi at the point of application, of plural component system from unpressurized parts A and B material supplies. In one example, a system includes a polyurethane spray foam (SPF) raw material supply including parts A and B and a fluid handling system that can deliver the SPF raw material at low pressure to a metal spray gun in metered amounts through separate material fluid paths/conduits via a heated hose length and a whip hose. The fluid handling system can also deliver air at low pressure to the spray gun through separate air stream paths so that the air is communicated to the part A and B material conduits forward of the part A and B material input locations, where they are supplied separately to a mixing nozzle that is engaged at an end of the spray gun.

A painting device is provided with: a bell-shaped cup for discharging paint; a housing for holding the cup so as to be freely rotatable; and first tip openings disposed on the outside in the radial direction on the base end side of the tip side outer peripheral edge of the cup and throwing paint onto a workpiece by spraying shaping air in the direction of the tip. When a tangent line that is tangent to the tip side outer peripheral edge of the cup from a first tip opening is drawn in a front view of the painting device, the first tip opening sprays shaping air at an inclination more to the inside in the radial direction of the cup than the tangent line.

A device for disinfecting, sterilizing and/or maintaining medical, especially dental, instruments comprises a maintenance and cleaning chamber for accommodating instruments to be conditioned and means for supplying different cleaning or maintenance media for cleaning, disinfecting or sterilizing and/or maintaining the instruments in subsequent steps. The start times of the conditioning cycles for the different instruments are staggered.

The invention relates to a device for rotating a fluid inside a spray nozzle, this device comprising a body defining at least one helical slot and/or a helical hole for the passage of all or part of the fluid. This device can be secured to a spray nozzle or a needle valve closing the spray nozzle. The invention also relates to an applicable device comprising such a device.
