Abstract:
A paint circulation system includes a paint reservoir, a pressure transducer, a servo motor driven pump, an electronic servo drive and controller, one or more paint applicators in a spray booth and an isolation valve. The pressure transducer provides a signal to the controller indicating the current pressure in the system. The servo pump is controlled by the controller and servo drive, draws paint from the reservoir and maintains the desired pressure in the system. The isolation valve is downstream from the applicators and is closed when paint is requested by the applicators. When paint is flowing to the applicators, the servo drive adjusts pump speed to maintain the desired system pressure as sensed by the pressure transducer. When paint is not requested, the isolation valve is open and the servo pump motor operates to provide a minimum flow rate to circulate paint from, and return it to, the reservoir.

Abstract:
A dosage device for extruding a bicomponent or a monocomponent sealant, particularly for an automatic machine for sealing a perimetric edge of an insulating glazing unit constituted by at least two glass sheets and by at least one spacer frame, having a finite width, is arranged proximate to the perimeter at a finite distance from the margin of the glass sheets, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the sealant, which can be activated alternately, in a first feeding step and in a third feeding step, so that one of them provides flow continuity to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activatable, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.
Abstract:
An apparatus includes a spray module with at least one column of spray nozzles. Each spray nozzle is configured to deliver a processing substance on a semiconductor substrate during a process for semiconductor manufacturing as the semiconductor substrate moves past the spray module. The at least one column of spray nozzles is arranged with respect to a direction of travel of the semiconductor substrate so the semiconductor substrate passes the spray nozzles. A location module identifies a location of the semiconductor substrate with respect to the spray module. A spray pattern module determines a spray pattern of where a processing substance is to be delivered to the semiconductor substrate and a nozzle control module actuates each spray nozzle independently based on the spray pattern and a location of the semiconductor identified by the location module.

Abstract:
An electro-mechanical system for the collection and recovery of materials inside thin-film deposition facilities, comprising multiple elements able to intercept the wasted particles of material during a coating process. These elements are disposed in individual modules (1, 5), possibly combined in multiple configurations according to the shape of the deposition chamber; swivel, depending on the material to be recovered, thanks to a power unit (4), a transmission system (6, 10, 15a, 15b), an electronic interface (9) to automate the rotation of the elements. These elements can be palettes (3) placed vertically in each of the modules (1, 5), made of a composite material, characterized by a core of metallic material or alumina and by two surface polymeric layers with low adhesion to the selected core and therefore easily removable, but at the same time resistant to the temperature and pressure conditions inside the deposition chamber.
