Abstract:
A method of applying liquid in a finely divided form onto a moving surface and an apparatus for carrying out that method. A flow of air containing suspended liquid particles is passed substantially parallel to the moving surface and across its direction of movement within a container which extends across the width of the moving surface. The container has a slit or a series of openings facing the moving surface, through which slit or openings at least a part of the liquid particles entrained in the air flow are deflected and passed substantially normal to the surface to be deposited thereon.
Abstract:
An apparatus for coating a recorded disc with a thin layer of a lubricant includes a chamber which is divided into two sections by a baffle extending across the chamber and vertically downwardly from the top of the chamber to a point spaced from the bottom of the chamber. An atomizer is mounted at the top of one section of the chamber and is connected to a source of air under pressure and a supply of lubricant. The atomizer is adapted to generate droplets of lubricant in the one section. An air inlet port in the side of the chamber opens into the one section and is connected to a source of air under pressure. An outlet opening is at the top of the other section of the chamber. The flow of air into the one section is controlled to carry the smaller droplets of the lubricant around the bottom of the baffle and up the other section to flow out of the chamber through the outlet port. The larger droplets fall to the bottom of the chamber and are carried away through a drain outlet in the bottom of the chamber.
Abstract:
A spraying arrangement having particular adaptability for use in combination with a conveyor installation characterized by conventional sprayer equipment for painting or coating production parts, where excess paint or coating material is deposited on a back up shield, the latter serving to overcome, or at least minimize, overspray.Particular importance of the arrangement lies in the fact that the load capabilities of the conveyor can be more fully utilized, i.e. the parts under process can be sprayed from opposite sides of the aforesaid shield, being mounted on the same conveyor hanger.The shield may be in the form of selectively movable porous material and, in the instance of electrostatic paint spraying, a grid, charged with the same electrical potential as the part, is disposed within passes of the shield for even more effective excess material collecting purposes.
Abstract:
This is an improved type of painting or misting shield which contains an upright, preferably concave curved member (which is made of hard-baked enamel when the shield is used as a painting shield) to serve as a backstop or shield while either misting plants with a water mist spray or spraypainting with a paint spray. The shield also comprises a trough located at the bottom thereof to serve as a means for trapping the unused water or paint that has been stopped by the shield.
Abstract:
A vegetation spraying assembly including a support framework mounted on the front of a tractor and movable vertically by hydraulic cylinders. A plurality of arms extend forwardly from the framework to distal ends supporting wedge-shaped guards with spraying nozzles supported rearwardly of the guards and aimed to spray rearwardly in a horizontal pattern. A plurality of collector trays are supported on the framework rearwardly of the spray nozzles. Each collector tray is an integral plastic member having end walls and a vertical back wall extending between the end walls. Each collector tray has a forwardly facing spray-receiving opening and a catch basin below the opening. A projection extends along and below the opening and is defined by first and second walls extending rearwardly from an apex for engaging and preventing vegetation from engaging the opening. A lip wall extends upwardly and forwardly from one of the walls defining the projection and defines the lower periphery of the opening. A short top wall extends forwardly from the top of the back wall for defining the top periphery of the opening. The end walls define the end peripheries of the opening and slant downwardly and forwardly from the top wall to the lip wall so that the periphery of the opening is disposed in a plane which is at an acute angle relative to the back wall. A fibrous pad or screen is supported in the opening at an angle for receiving the liquid spray which does not engage vegetation which spray passes therethrough and collects in the catch basin of each collector tray.
Abstract:
Apparatus and a method for the selective conditioning, wetting and coating of particles with a selective wetting agent. The apparatus includes a horizontally extending surface capable of vibration which vibration induces uniform translatory movement along the surface to particles upon the surface. A vertically extending barrier is on the surface and extends across the surface and at right angle to the direction of movement of particles upon the surface. A means for spraying the selective wetting agent onto the particles as they move along the surface and before they reach the barrier is provided. Means for removing excess wetting agent are provided on the surface along the direction of movement of the particles after the barrier. A pool of the selective wetting agent forms behind the barrier upon the surface.
Abstract:
An improved hot end glass container coating system comprises a conveyor for transporting hot glass containers, first and second pairs of spray coating units and exhaust units reversely opposed adjacent the sides of the conveyor, an air flow control unit and a coating liquid measuring and flow control unit.
Abstract:
Process for the continuous production of irregular, optionally multicolor, design effects on flat structures, preferably on the basis of textile materials, especially of carpet material, by spreading a liquid dyestuff composition onto a substrate web to be dyed or colored, and then fixing the dyestuff applied according to usual methods, which comprises applying the dye liquor by means of flat or curved rotating disks arranged in horizontal position, which divide the dye liquor supplied continuously or in drops to their surfaces, owing to the centrifugal force imparted to it by the rotation of the disks, into individual drops of different size, which are then centrifuged from there owing to their weight under the influence of gravity and at a determined angle of spread, over the full width of the material web to be dyed or colored, which is horizontally passed beneath the disks, and device for carrying out this process.
Abstract:
Flow-coating apparatus comprising an open conveyor means for conveying an article to be coated over a gravity-fed spray nozzle positioned below the conveyor and above a sump for collecting the coating material issuing from the nozzle. The nozzle is designed to provide a continuous spray pattern of an elevation such that it extends upwardly through the conveyor means for contacting the article. A deflector is provided for intercepting the sprayed material before it passes through the conveyor and directing it into the sump except during those periods when the article to be coated is within the spray pattern.
Abstract:
An open framework is pivotally supported on a tractor or the like, and power operated means is connected therewith for adjusting the position of the framework. A supply tank is connected with a plurality of nozzles adjustably mounted on the framework. The framework defines a plurality of plant gathering spaces, said spray nozzles being adapted to spray plants disposed within such gathering spaces. A plurality of spray receiving means are mounted on the framework and positioned to receive spray from the various spray nozzles. These spray receiving means are connected with storage tank means supported by the framework.
