  • Patent number: 10155236
    Abstract: A Cold spray nozzle assembly for depositing powder material onto a component surface includes a primary spray nozzle, two or more secondary spray nozzles, and a support mechanism supporting each spray nozzle. Each spray nozzle deposits powder material on a single target point on the surface, a reference plane being defined normal to a surface plane at the target point. The primary nozzle is in a primary plane that is normal to the surface plane, and that defines a primary dihedral angle with the reference plane. An axis of the primary nozzle defines a primary nozzle angle with the surface plane. Each of the secondary spray nozzles is in a corresponding secondary plane, with each being normal to the surface plane and defining a respective secondary dihedral-angle with the reference plane. An axis of each secondary spray nozzle defines a respective secondary nozzle angle with the surface plane.

  • Patent number: 10047657
    Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine comprises a mixer housing including a wall defining an exhaust passageway having a longitudinal axis. A tubular swirling device housing extends along a first axis substantially transverse to the longitudinal axis. The tubular swirling device includes a plurality of openings through which exhaust gas enters. The exhaust gas within the tubular swirling device swirls about the first axis and exits at an outlet end of the tubular swirling device. A mixing plate is positioned immediately downstream of the tubular swirling device and includes apertures through which the exhaust gas exiting the outlet end of the tubular swirling device flows. The mixing plate swirls the exhaust about a second axis extending parallel to the longitudinal axis.

  • Patent number: 10016908
    Abstract: The present disclosure relates to processing a substrate including at least one sheet of paper, cardboard or carton by directing a jet stream of liquid nitrogen to a surface of the substrate via a jet nozzle; and by moving the jet nozzle at a distance from the surface. The jet stream can be unmodulated or modulated. For example, the jet stream can be modulated by a modulation unit such as to reduce the impact of the jet stream on the surface. In this way, the jet stream can be applied to score folding lines into the substrate. An unmodulated or on/off modulated jet stream can be applied to cut lines into the substrate. Thus, by applying an appropriate modulation to the jet stream, the processing can switch between cutting the substrate and scoring folding lines into the substrate.

The jet fountain also includes a surface disruptor that includes a body, a water inlet, a valve, a fluid outlet, and a trajectory adjuster emanating a second stream of fluid from the fluid outlet. The second stream of fluid may be positioned to intersect the first stream of fluid and perturb its laminarity. By adjusting a valve controlling the force and volume of flow of the second stream and/or by adjusting the trajectory adjuster, the intersection of the first and second streams may be modified and, therefore, the laminarity of the first stream may be modified. By disrupting the laminar surface of the first stream, light introduced into the first stream may be caused to refract outward from the first stream and thus enhance illumination of the first stream.

  • Patent number: 8393555
    Abstract: A moistening nozzle of a paper web comprises a frame into which air and water are fed. Inside the frame there is arranged a water nozzle wherewith water is conducted to an outlet of the moistening nozzle and an air nozzle wherewith air is correspondingly conducted to the outlet. The air nozzle and the water nozzle are arranged one within the other such that the air and the water form water mist that is sprayed out from the moistening nozzle. The air nozzle is provided with a thread that brings the air in swirling motion. The air nozzle comprises a sleeve part with an opening through which air is discharged and in said opening there is arranged a piece that is an integral part of the frame of the moistening nozzle, whereby a part of the moistening nozzle frame forms an inner edge of the air gap provided by said piece and the sleeve part.

  • Patent number: 8360340
    Abstract: The invention relates to methods and devices for spraying liquid during production processes requiring a uniform dispersion mixture, in particular in internal combustion engines requiring a fine fuel-air mixture, in the chemical industry for apparatuses for rinsing gas with liquid, which require a uniform coarse-dispersion mixture for reducing the drop entrainment of a rinsing liquid. The inventive method consists in collecting, during the liquid spraying, which is carried out by injecting a liquid at an angle to a gas flow, particles in those sectors of the spray cone that are appropriate to particles of specified sizes. The liquid spraying and collecting processes are carried out at one section of a laminar unidirectional gas flow. The collected particles form, when accumulated, a liquid that is returned for re-spraying.

  • Patent number: 8297529
    Abstract: A device is disclosed that uses a flow-control methodology to control sprays at very high precision and frequency. The device is based on an enhanced Coanda effect. The control flow is selectively applied to the region in which we desire the jet to vector and control the profile (width) of the jet. The control flow is introduced through multiple control flow ports surrounding the primary nozzle and adjacent to the Coanda surface. By selectively opening and closing different control flow ports the motion and profile of the jet can be controlled.

  • Patent number: 8282019
    Abstract: A cold spray nozzle assembly includes a venturi having converging and diverging portions interconnected at a throat. An air supply conduit is in communication with the venturi for supplying a carrier gas to the converging portion. A powder feed tube is in communication with the venturi for supplying a powder material. An adjustment member is arranged within the venturi and is axially moveable relative thereto between multiple positions. The multiple positions respectively provide multiple different areas or throat clearances including a desired area between the adjustment member and the venturi or throat clearance. As a result, the adjustment member can be axially positioned to achieve desired gas pressures, deposition rates, and accommodate machining tolerances and component wear based upon the selected area. A retention member maintains the adjustment member in the desired position during operation of the cold spray nozzle assembly.
