    Abstract: An apparatus for applying a coating of flowable material to articles, comprises a support for the articles, a metering feed roller having a number of uniformly distributed isolated pockets of predetermined capacity in its surface, and arranged with its axis of rotation parallel to the surface of the support, means for rotating the roller and for effecting relative movement between the roller and support along the support and in a direction substantially at right angles to the said axis of rotation, a horizontal feed hopper of which the roller forms a wall and which has an extension of its underside disposed close to the surface of the roller so as to confine the flowable substance to the pockets therein, while leaving the surface between the pockets free of the said substance, and means beyond the said extension for removing the substance from the pockets and projecting it on to the articles on the support. As shown, sheets 51 are conveyed through the apparatus by a belt 12, which, in part of its return course, dips into cleaning liquid in a tank 16, and is wiped by a rotary brush 17 and squeeze roller 22. The sheets 51 pass beneath a coating-apparatus comprising a metering roller 34 having longitudinal peripheral grooves 37 and rotating in coating liquid held between a thin steel sheet lining a housing 43, and pressed against the roller 34 by an inflatable bag 40, and two side-plates 31. The roller 34 is driven from a motor 50 through a variable gear-box 4, and its speed is indicated by a tachometer 91. The liquid is wiped from the roller 34 by a rotary brush 47, and projected towards the sheets 51 as the bristles pass over a blade 52. A brush 72 is secured under the blade 52 to prevent drips falling therefrom. Any coating remaining on the roller 34 is removed by an air blast issuing from an adjustable nozzle 57. The coating liquid is circulated to the coating device from a tank 24, provided with a stirrer 27, through pipes 69, 29 and 71, by a pump 28. The globules of coating material, after deposition, may be subjected to a smoothing action by a brush 63 mounted to move bodily in a circle about an upright axis.

    Abstract: The invention provides a combination of a nozzle and a vacuum hood. The vacuum hood has a chamber that surrounds the tip of the nozzle and removes residue from the tip by a vacuum which flows in the chamber past the nozzle tip. This vacuum catches and removes residue from the nozzle tip and prevents the reside from interfering with the spraying action or dripping down. The method of the instant invention provides for dispensing a fluid from a nozzle without dripping fluid from the nozzle having a vacuum hood. The method comprises: (a) dispensing a fluid on a rotating semiconductor wafer through a nozzle over the wafer; (b) terminating the fluid flow through the nozzle; (c) creating an upward flow of gas about the dispensing nozzle when the flow of fluid through the nozzle is terminated; (d) capturing any fluid residue from the nozzle in the upward flow of gas; (e) removing the wafer and positioning another wafer; and (f) terminating the upward flow of gas; and repeating the process of steps (a) through (f).

    Abstract translation: 本发明提供喷嘴和真空罩的组合。 真空罩具有围绕喷嘴尖端的腔室，并且通过在腔室中流过喷嘴头的真空去除尖端的残留物。 该真空捕捉并从喷嘴尖端去除残留物并防止驻留物干扰喷雾作用或滴落。 本发明的方法提供了从喷嘴分配流体而不从具有真空罩的喷嘴滴下流体。 该方法包括：（a）通过晶片上的喷嘴在旋转的半导体晶片上分配流体; （b）终止通过喷嘴的流体流动; （c）当终止通过喷嘴的流体流动时，在分配喷嘴周围产生向上的气流; （d）在向上的气体流中捕获来自喷嘴的任何流体残留物; （e）移除晶片并定位另一个晶片; 和（f）终止气体的向上流动; 并重复步骤（a）至（f）的处理。

    Abstract: A spray mist collector for use with a spray gun, such collector connected to a vacuum source to draw the spray mist surrounding the spray of paint or other sprayable material emitted from the nozzle of the spray gun to the intake apertures of the collector where the particles suspended in the spray mist are trapped by a filter. The spray mist collector has a connection mechanism for connection to the spray gun whereby its expanded intake apertures are automatically pointed at the spray mist surrounding the spray of paint as the painter directs it on to the work object. The filters are replaceable when they become filled, and an adjustable signal mechanism may also be included to indicate when the filters should be changed. The rearward duct portion of the spray mist collector is connected to an elongated flexible air hose or air conduit which leads to a vacuum source. The spray mist collector may be large for use with large spraying equipment or small for use with small spraying appliances such as aerosol paint spray cans. The duct assembly of the spray mist collector may even be formed integrally with certain types of spray guns or spray equipment. Whether integrally formed or removably connectable, the spray mist collector is made of light weight materials which add very little weight to the spray equipment to which it is attached.

    Abstract: A variable form spray system includes a robot manipulator, a masking tool assembly integrated with the manipulator, sealer supply hardware which supplies spray material to the manipulator and sealer recovery hardware which recovers material sprayed and skived by the masking tool assembly. Spray pattern form is controlled by collecting overspray using adjustable skive manifolds of the assembly on each side of the spray pattern which function to vacuum off the edges of the airless spray pattern. The positions of the skive manifolds are programmable.
