Claims
- 1. A liquid atomizing device comprising, in combination, a disk having a flat circular face mounted for rotation, means for rotatably driving said disk, a fluid conveying capillary tube mounted for delivering fluid to said face at a low but constant flow rate, a reservoir for supplying fluid to be atomized to said tube, the fluid delivering end of said tube being spaced from said face so that a liquid drop formed at the tube end is just contacted by the face and the face rotation rotates the drop while pulling a thin, uniform, continuous fluid film on the face from the drop, wherein the liquid is a monomeric liquid resin, the disk is formed of glass and has a one-inch diameter, the means for rotatably driving said disk rotates it about its center at a rate within the range of about 3000 to about 5000 revolutions per minute, and the capillary tube is a 20 mil capillary tube and is mounted to deliver fluid to said face at a point radially spaced about 3/8 inch from the center of the disk, whereupon said film is thrown in atomized droplets from the periphery of the disk.
- 2. A liquid vaporizing apparatus for vacuum vapor deposition of a material from liquid monomer form comprising, in combination, a vaporization chamber having a nozzle opening for discharging vapor, a one-inch diameter, glass disk having a flat circular face mounted for rotation in said chamber, means for rotatably driving said disk about its center at a rate within the range of about 3000 to about 5000 revolutions per minute, a 20 mil, fluid conveying capillary tube mounted in said chamber for delivering fluid to said face at a low but constant flow rate and at a point radially spaced about 3/8 inch from the center of the disk, a reservoir for supplying fluid to be atomized to said tube, the fluid delivering end of said tube being spaced from said face so that a liquid drop formed at the tube end is just contacted by the face and the face rotation rotates the drop while pulling a thin, uniform, continuous fluid film having a thickness of about one micron or less on the face from the drop, a band heater in said chamber defining a heating surface surrounding the periphery of said disk, whereby said film is thrown in atomized droplets from the periphery of said disk and said droplets are flash vaporized on said surface.
