Abstract:
An impingement plate atomizer apparatus includes an electrostatically charged longitudinal member having an upper surface sized and shaped to receive a liquid cryogen thereon, a lower surface opposite to the upper surface, and at least one hole extending through the longitudinal member; an ultrasonic transducer in contact with the longitudinal member for providing ultrasonic energy thereto for atomizing the liquid cryogen into an electrostatically charged cryogen fog. A method is also provided for providing an eiectrostaticaily charged cryogen fog.
Abstract:
The invention relates to a process and an apparatus for coating glass (2) by means of a method using at least one or more liquid raw materials which react essentially on at least a portion of the glass substrate forming a coating on it. At least part of the liquid raw materials is atomized to droplets (17) with one or more two-fluid atomizer and at least a fraction of the gas used in the one or more two-fluid atomizers is electrically charged such that at least a fraction of the droplets (17) become electrically charged during or after the atomization. According to the invention the droplets (17) are formed into a separately created electric field.
Abstract:
A fluxer (10) applies powdered flux (11) to an object (12). The fluxer (10) includes an enclosure (14) that defines a chamber (28) where the object (12) is fluxed. The enclosure (14) includes an inlet (24) for receiving the object (12) into the chamber (28) prior to application of the flux (11) and an outlet (26) for discharging the object (12) from the chamber (28) after the flux (11) has been applied. A conveyor (16) extends through the enclosure (14) for traversing the object (12) into and out of the chamber (28). The fluxer (10) also includes a hopper (18) for storing the flux (11) and an applicator (20) in fluid communication with the hopper (18) for applying the flux (11) to the object (12). A flux recovery system (22) is in fluid communication with the chamber (28) to introduce and maintain a negative pressure within the chamber (28). As a result, excess flux (11) is retained within the enclosure (14). This excess flux (11) can then be recovered and recycled to the hopper (18).
Abstract:
Provided herein is a coating system using a spray nozzle, the coating system comprising: a support where a substrate is disposed; a spray nozzle configured to inject towards the substrate liquid that has gone through a primary atomization by collision with gas; a voltage applier configured to apply voltage to the spray nozzle so that the liquid injected from the spray nozzle includes electric charge, and to generate an electric field between the support and the spray nozzle by the voltage applied to the spray nozzle and perform a secondary atomization of the liquid injected from the spray nozzle; and a transferrer configured to transfer at least one of the support and the spray nozzle.
Abstract:
A method and apparatus for adjusting the relative movement between flocked fibers and an object to be flocked is disclosed. Fibers move along a curved or arcuate path which includes both vertical and horizontal movement of the fibers from a flocking machine to the object to be flocked. The method improves the flocking process quality and increases production speed and output.
Abstract:
Workpieces, which are conveyed by a conveying device along a conveying path, are heated by a heating and degreasing coil. Then, resin powder is downwardly sprayed from a nozzle of a coating device to each corresponding one of the workpieces, which are conveyed by the conveying device. The workpieces are thereafter heated by a heating and curing coil. At each of the heating coils, a dummy member, which is made of an electrically conductive material, is displaced from a retracted position to a forward position, which is located between the corresponding heating coil and a corresponding adjacent part of the conveying path of the conveying device, when an empty one of mount locations of the conveying device reaches the forward position of the dummy member.

Abstract:
Apparatus and method for electrostatic charging of a container for an electrostatic coating operation includes a support member for supporting a container during an electrostatic coating operation with the support member comprising a non-metallic conductive material or electrically semiconductive portion that directly contacts a surface of the container. The electrically semiconductive portion comprises non-metallic, resistive or low conductivity material and is coupled to a source of electrical energy such that the container is electrostatically charged to an opposite polarity to offset or reduce electrostatic charge build up produced by the electrostatic coating operation.
