  • Patent number: 6322008
    Abstract: The nozzle (10) has at least one pair of openings (18, 20) located on its front face (28) along a common axis (32). Each opening (18, 20) is spaced apart (26) from and angled towards its pair mate. A non-atomized solid liquid stream (14, 16) is directed through each circular opening (18, 20) by a pressurized source. The two streams (14, 16) from each pair of openings (18, 20) meet at a spaced apart point in front of the nozzle face (28) to create a flat triangular pattern of liquid (24).

  • Patent number: 4854504
    Abstract: A fiberglass spray nozzle arrangement is described for controlling the spray flow configuration of a resin-catalyst mixture which is atomized exteriorly of the nozzle. Resin nozzle, catalyst nozzle and control air nozzle devices are included in spaced apart relation in this nozzle arrangement. The resin nozzle sprays resin in a spray stream which is intersected by control air jets from the flow control nozzle and catalyst spray from the catalyst nozzle in series. The resulting spray mixture forms a continuous flat fan having no splits or tails at the work.
