Abstract:
The invention relates to a method and to an apparatus for applying a UV print varnish onto a moving web- or sheet-shaped print substrate freshly printed in a flatbed rotary printing press (offset). A plurality of spray nozzles continuously spray a spray mist comprising UV print varnish onto the printed first form and/or second form print. In order to guide the spray jet, guide plates are provided over the entire width of the print substrate. Larger UV print varnish droplets (interfering droplets) that accumulated on the insides of the two guide plates are picked up from there by a UV print varnish droplet collection device and transferred to a UV print varnish droplet removal device. Said device then removes the collected UV print varnish droplets (interfering droplets).
Abstract:
During blasting work, large quantities of blasting material (granules, glass beads, slag and sand) together with residues of blasted colour coating are projected over a large area after impact with the surface being blasted. This results in the pollution of large areas of the surrounding environment. The large quantities of dust produced cause problems for the population over a much wider area. The inventive suction device prevents blasting material, dust and liquids from escaping from the blasting site and the area immediately surrounding the blast nozzle into the environment during blasting work. A second suction system which functions separately allows the device, with its integrated blast pressure nozzle, to hold itself steady automatically, even in extreme working positions, e.g., overhead, hereby relieving the operator of this task, and can still be moved laterally in any direction. The high suction capacity of the device ensures that the blasting material or liquids which rebound or are projected off of the surface during blasting work are extracted without leaving a residue and collected in containers. The inventive suction device can also be used for drying the expansion joints of concrete slabs etc. and prevents the pollution of the environment with residues of dust, joint material and chemical material.
Abstract:
A controlled droplet application (CDA) nozzle including a cone having plural ridges disposed longitudinally on an interior surface of the cone; and a fin assembly connected to the interior surface, the fin assembly comprising a plurality of fins extending between a central portion of the cone and the interior surface, wherein adjacent pairs of the plurality of fins and the interior surface at least partially define a respective compartment for the collection of a defined volume of fluid.

Abstract:
A line-marking apparatus, comprises a pair of primary wheels 58, 60; a pair of stabilizer wheels 106 each attached to and separately moveable with respect to the apparatus between laterally extended and closed positions; a mask 10 comprising an edge 22, 24 for defining the shape of marking fluid when sprayed on a surface; a threaded shaft 64 by which the mask is adjustably mounted in the apparatus; ducting 72 and battery-powered air impellers 74 mounted at a hub region of the primary wheel to provide an air flow at said shape-defining edge, which air-flow is arranged to direct sprayed marking fluid material from the shape- defining edge and within the marking fluid sprayed on the surface; a holder 41 in which an aerosol canister 108 is movably mountable, spring means 123 operative between the aerosol canister and the holder, the spring means being biased to complement the action of the aerosol outlet valve spring; and an outlet valve opening mechanism 120, 124 acting with mechanical advantage on the aerosol canister in opposition to the spring means. The holder 41 may be set at different heights by a button 52 selectively engageable in one of a series of vertically spaced apertures.
Abstract:
A controlled droplet application (CDA) nozzle has a cone having plural ridges disposed longitudinally on an interior surface of the cone. The cone has a circumferential lip having grooves defined by the plural ridges, and a directional shroud having one or more arcs disposed on the surface of the shroud that cover all but a portion of the lip.
Abstract:
The present disclosure relates to a system and method for spraying a target object. A recapture shell may partially contain the target object and mitigate dispersal of overspray. A leading front of higher-than ambient air pressure and a trailing front of lower-than ambient air pressure are created to partially isolate recirculating air within a target space in the recapture shell to enhance spray coverage and mitigate spray loss. Embodiments of the present disclosure may be used for agricultural, automotive, aerospace, and other applications to emit, contain, and/or recapture a spray.
Abstract:
A process kit for a semiconductor processing chamber is provided. In one embodiment, a process kit includes an annular deposition ring body comprising a trough recessed into an upper surface of the body wherein a lowest point of the trough extends to at least half of the thickness of the ring body as defined by a top wall and a bottom wall. In another embodiment, a process kit includes an annular deposition ring body comprising a sloped upper wall defining at least a portion of an upper surface of the body, wherein a peak of the sloped upper wall extends from an inner wall of the body to at least half of a distance between the inner wall and an outer wall of the body.
